Description

一种LED灯具A kind of LED lamp

技术领域technical field

本发明属于照明装置的技术领域，具体地说是涉及一种LED灯具。The invention belongs to the technical field of lighting devices, and in particular relates to an LED lamp.

背景技术Background technique

LED灯具因具有安装、维修方便，省电、高亮度及体积小的特性，被广泛运用于各种场所，其核心部件发光二极管（Lighting-Emitting Diode, LED）作为新一代固态能源，具有寿命长、高效节能、绿色环保等优点。LED lamps are widely used in various places because of their convenient installation and maintenance, power saving, high brightness and small size. As a new generation of solid-state energy, the core component of LED lamps, Light-Emitting Diode (LED), has the advantages of long life, high efficiency, energy saving, and environmental protection.

但现有技术的LED灯具，存在以下问题：
1、现有技术的LED灯具，其中间部位需设置引挂器，而灯珠仅能设置在引挂器的径向的外侧，从而造成LED灯具的中间部形成暗区的问题，使得出光不均匀
2、LED灯具中光源模组一般朝一个方向发光，LED灯点亮时，在LED灯具的光源模组的发光方向外易出现发光暗区。 However, the LED lamps of the prior art have the following problems:
1. In the LED lamps of the prior art, a hanger needs to be installed in the middle part, and the lamp beads can only be set on the radially outer side of the hanger, which causes the problem that a dark area is formed in the middle part of the LED lamp, making the light output uneven
2. The light source module in the LED lamp generally emits light in one direction. When the LED lamp is lit, a dark area of light is likely to appear outside the light emitting direction of the light source module of the LED lamp.

3、LED灯具中一般将电源模组和光源模组分开放置，因电源模组需要额外的空间放置，一方面会影响LED灯的高度，致使产品的体积增大，进而提高了包装及库存成本；另一方面若电源模组离光源模组较远，电源模组与光源模组之间的电连接不稳定。3. In LED lamps, the power module and the light source module are generally placed separately. Because the power module requires additional space to be placed, on the one hand, it will affect the height of the LED lamp, resulting in an increase in the volume of the product, which in turn increases the cost of packaging and inventory; on the other hand, if the power module is far away from the light source module, the electrical connection between the power module and the light source module is unstable.

4、光源向下的设置，会使天花板面有冷感，不适用于卧室等居家环境。4. The downward setting of the light source will make the ceiling feel cold, so it is not suitable for home environments such as bedrooms.

5、现有LED灯具存在整灯厚度过厚，导致不美观的问题。5. Existing LED lamps have the problem that the thickness of the entire lamp is too thick, resulting in unsightly appearance.

综上所述，鉴于现有技术的LED灯具存在的不足和缺陷，如何设计LED灯具，以解决上述LED灯具中间存在暗区问题、单一出光问题等，是亟待本领域技术人员解决的技术问题。To sum up, in view of the deficiencies and defects of the existing LED lamps, how to design LED lamps to solve the problem of dark areas and single light output in the above-mentioned LED lamps is a technical problem that urgently needs to be solved by those skilled in the art.

具体实施方式Detailed ways

为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是，本发明可以通过许多不同的形式来实现，并不限于下面所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容理解的更加透彻全面。下文中关于方向如“轴向方向”、“上方”、“下方”等均是为了更清楚的表明结构位置关系，并非对本发明的限制。在本发明中，所述“垂直”、“水平”、“平行”定义为：包括在标准定义的基础上±10%的情形。例如，垂直通常指相对基准线夹角为90度，但在本发明中，垂直指的是包括80度至100度以内的情形。In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. The directions such as "axial direction", "above" and "below" in the following text are all for the purpose of more clearly indicating the structural positional relationship, and are not intended to limit the present invention. In the present invention, the definitions of "vertical", "horizontal" and "parallel" include the situation of ±10% based on the standard definition. For example, vertical usually means that the included angle with respect to the reference line is 90 degrees, but in the present invention, vertical refers to the situation including 80 degrees to 100 degrees.

如图1~2所示，本发明在一实施例中提供一种LED灯具，该LED灯具包括：底座1、设置于底座1上的光源部2、与光源部2电性连接的电源部3、罩设于光源部2和电源部3外的灯罩4以及用于与外部进行电性连接的引挂器5。As shown in FIGS. 1-2 , the present invention provides an LED lamp in an embodiment. The LED lamp includes: a base 1 , a light source part 2 disposed on the base 1 , a power supply part 3 electrically connected to the light source part 2 , a lampshade 4 covering the light source part 2 and the power supply part 3 , and a hanger 5 for electrically connecting with the outside.

如图1、2、7所示，光源部2可包括带有光源的第一光源组件21。第一光源组件21朝向LED灯具的中心发光。第一光源组件21包括第一灯板210，第一灯板210上包括用于发光的灯珠200。第一光源组件21的第一灯板210上的灯珠200可均匀设置，即每个第一灯板210上的相邻的两个灯珠200的间隔距离相同或大致相同，从而保证出光的均匀。灯珠200可采用相同或不同的色温，从而可以调节整灯出光的色温。第一灯板210可为FR4材质，能起到环保、耐高温等效果。As shown in FIGS. 1 , 2 and 7 , the light source part 2 may include a first light source assembly 21 with a light source. The first light source assembly 21 emits light toward the center of the LED lamp. The first light source assembly 21 includes a first lamp board 210, and the first lamp board 210 includes lamp beads 200 for emitting light. The lamp beads 200 on the first lamp board 210 of the first light source assembly 21 can be evenly arranged, that is, the distance between two adjacent lamp beads 200 on each first lamp board 210 is the same or approximately the same, so as to ensure uniform light output. The lamp beads 200 can adopt the same or different color temperatures, so that the color temperature of the light emitted by the entire lamp can be adjusted. The first light board 210 can be made of FR4 material, which can have the effects of environmental protection and high temperature resistance.

光源部2还可包括一第二光源组件22，朝向LED灯具的外侧发光。第二光源组件22包括第二灯板220，第二灯板220上包括用于发光的灯珠200。灯珠200可采用相同或不同的色温，从而可以调节整灯出光的色温。因相邻的两个第二光源组件22连接部存在距离，所以为保证第二光源组件22的出光均匀，第二灯板220上的灯珠200可采用两端密的排布方式。即第二灯板220上靠近两端的两个相邻的灯珠200之间的距离L1小于第二灯板220中间位置的两个相邻灯珠200之间的距离L2。通过相邻两个灯珠200之间的距离设置，能减弱相邻的两个第二光源组件22连接部方向的暗区，使LED整灯出光均匀。具体的，两端的两个相邻的灯珠200之间的距离L1与最中间两个相邻灯珠200之间的距离L2的关系为，1:2≤L1:L2＜1；优选的，两端的两个相邻的灯珠200间的距离L1与最中间两个相邻灯珠200之间的距离L2的关系为，1:2≤L1:L2≤4:5；更优的，两端的两个相邻的灯珠200之间的距离L1与最中间两个相邻灯珠200之间的距离L2的关系为，1:2≤L1:L2≤2:3。第二灯板220可为FR4材质，能起到环保、耐高温等效果。本实施例中，每块第二灯板220上设置6颗灯珠200。The light source part 2 may further include a second light source assembly 22, which emits light toward the outside of the LED lamp. The second light source assembly 22 includes a second lamp board 220 , and the second lamp board 220 includes lamp beads 200 for emitting light. The lamp beads 200 can adopt the same or different color temperatures, so that the color temperature of the light emitted by the entire lamp can be adjusted. Due to the distance between the connecting parts of two adjacent second light source assemblies 22 , in order to ensure uniform light emission from the second light source assemblies 22 , the lamp beads 200 on the second lamp board 220 can be arranged closely at both ends. That is, the distance L1 between two adjacent lamp beads 200 near the two ends on the second lamp board 220 is smaller than the distance L2 between two adjacent lamp beads 200 in the middle of the second lamp board 220 . By setting the distance between two adjacent lamp beads 200, the dark area in the direction of the connecting portion of two adjacent second light source assemblies 22 can be weakened, so that the entire LED lamp emits light evenly. Specifically, the relationship between the distance L1 between the two adjacent lamp beads 200 at the two ends and the distance L2 between the two most adjacent lamp beads 200 in the middle is 1:2≤L1:L2<1; preferably, the relationship between the distance L1 between the two adjacent lamp beads 200 at both ends and the distance L2 between the two adjacent lamp beads 200 in the middle is 1:2≤L1:L2≤4:5; more preferably, the distance L1 between the two adjacent lamp beads 200 at both ends and the middlemost The relationship of the distance L2 between two adjacent lamp beads 200 is 1:2≤L1:L2≤2:3. The second light board 220 can be made of FR4 material, which can achieve effects such as environmental protection and high temperature resistance. In this embodiment, six lamp beads 200 are arranged on each second lamp board 220 .

如图7~8、10~12所示，底座1包括多个光源支撑部11，光源支撑部11可用于架设光源部2。多个光源支撑部11首尾相互连接，形成一个整体。多个光源支撑部11形成的整体，环绕电源罩32设置。本实施例中，底座1包括9个光源支撑部11，从而在节约成本的同时，有效的减少了各光源支撑部11连接处的暗区。于其他实施例中，光源支撑部11亦可采用3个、6个、12个、18个等其他设计。光源支撑部11可为朝向灯罩4方向的凸台或凸面，亦或其他能够支撑光源部2的结构。本实施例中，光源支撑部11呈凸台结构。从LED灯具的高度方向上看，单个光源支撑部11的截面呈一等边三角形或大致等边的三角形。为使光源部2的灯珠200发出的光不被阻挡，且均匀的照亮LED灯具的中间区域，在LED灯具高度的方向上，灯珠200可设置在光源支撑部11的靠上部位，且光源支撑部11的高度H1大于电源罩12露出于底座1的高度H2。即，光源支撑部11的高度H1与电源罩12露出于底座1的高度H2的比为，H1:H2≥1；优选的，光源支撑部11的高度H1与电源罩12露出于底座1的高度H2的比为，H1:H2≥1.3；更优的，光源支撑部11的高度H1与电源罩12露出于底座1的高度H2的比为，H1:H2≥1.5。As shown in FIGS. 7 to 8 and 10 to 12 , the base 1 includes a plurality of light source supporting parts 11 , and the light source supporting parts 11 can be used for erecting the light source part 2 . A plurality of light source supporting parts 11 are connected end to end to form a whole. The whole formed by the plurality of light source supporting parts 11 is arranged around the power cover 32 . In this embodiment, the base 1 includes nine light source supporting parts 11 , thereby effectively reducing the dark area at the connection of each light source supporting part 11 while saving costs. In other embodiments, other designs such as 3, 6, 12, and 18 light source support parts 11 may also be used. The light source supporting portion 11 can be a boss or a convex surface facing the lampshade 4 , or other structures capable of supporting the light source portion 2 . In this embodiment, the light source supporting portion 11 is in a boss structure. Seen from the height direction of the LED lamp, the cross-section of the single light source support part 11 is an equilateral triangle or a roughly equilateral triangle. In order to prevent the light emitted by the lamp bead 200 of the light source part 2 from being blocked and uniformly illuminate the middle area of the LED lamp, the lamp bead 200 can be arranged on the upper part of the light source support part 11 in the direction of the height of the LED lamp, and the height H1 of the light source support part 11 is greater than the height H2 of the power cover 12 exposed from the base 1.

底座1对朝向LED灯具中心发光的第一光源组件21发出的光，具有反射作用。第一光源组件21发出的光至少部分直射至底座1上，后经底座1的反射作用，从灯罩4射出。底座1可包括一反射层，反射层可以是白漆涂层，或覆膜，亦或是底座1本身具有反射功能的材质层。The base 1 has a reflective effect on the light emitted by the first light source assembly 21 that emits light toward the center of the LED lamp. The light emitted by the first light source assembly 21 is at least partly directed onto the base 1 , and then emitted from the lampshade 4 after being reflected by the base 1 . The base 1 may include a reflective layer, and the reflective layer may be a white paint coating, or a coating, or a material layer of the base 1 itself that has a reflective function.

如图1~2、10~11所示，底座1包括一个凹部12，用于容置引挂器5。电源部3可部分容置于凹部12中。电源部3可包括一电源板31，电源板31容置于凹部12中，并通过导线/端子分别与光源部2以及引挂器5进行电性连接。电源部3还可包括一电源罩32，电源罩32罩设于电源板31之上，并部分容置于凹部12中。电源罩32可采用PC材质，以起到防止电源板31其他部件发生不必要的电性连接，产生漏电/触电的风险。电源罩32也可采用金属材质，从而使电源板31在工作时产生的热量能通过热辐射传递至电源罩32后，通过电源罩32的散热效果，将热量散发出去，起到更好的散热效果。并且通过金属材质的电源板32的隔绝作用，能防止燃烧着火，同时能起到更美观的作用。电源罩32还可采用金属材质与PC材质结合的方式，即靠近电源板31的一侧为PC材质，用于起到绝缘作用；在LED灯具的高度方向上，远离电源板31的一侧为金属材质，用于提高散热效果，防止着火燃烧，起到美观作用。As shown in FIGS. 1-2 and 10-11 , the base 1 includes a concave portion 12 for accommodating the hanger 5 . The power supply unit 3 can be partially accommodated in the concave portion 12 . The power supply unit 3 may include a power supply board 31 , which is accommodated in the concave portion 12 and is electrically connected to the light source unit 2 and the hanger 5 through wires/terminals. The power supply part 3 may further include a power supply cover 32 , the power supply cover 32 is disposed on the power supply board 31 and partially accommodated in the recess 12 . The power cover 32 can be made of PC material to prevent unnecessary electrical connection of other components of the power board 31 and the risk of electric leakage/electric shock. The power supply cover 32 can also be made of metal, so that the heat generated by the power supply board 31 during operation can be transferred to the power supply cover 32 through thermal radiation, and then the heat can be dissipated through the heat dissipation effect of the power supply cover 32, so as to play a better heat dissipation effect. In addition, through the insulating effect of the power supply board 32 made of metal, it can prevent burning and igniting, and at the same time, it can play a more beautiful role. The power supply cover 32 can also adopt the combination of metal material and PC material, that is, the side close to the power supply board 31 is made of PC material, which is used for insulation; in the height direction of the LED lamp, the side away from the power supply board 31 is made of metal material, which is used to improve heat dissipation, prevent fire and burn, and play an aesthetic role.

从LED灯具的高度方向的截面看，电源罩32的一部分位于底座1的凹部12之上，一部分位于底座1的凹部12之中。电源罩32可包括用于支撑的支撑部321。支撑部321部分设置于凹部12之中，用于支撑电源罩32的中心部位。支撑部321可呈一朝向凹部12的凸起。支撑部321围绕着引挂器5设置。进一步，支撑部321可包括一个或者多个支撑加强构件3211。支撑加强构件3211位于支撑部321的周侧，对支撑部321起到加强其支撑强度的作用。支撑部321还可包括一个或者多个加强筋3212。加强筋3212从支撑部321处朝向电源罩32的边缘延伸，并具有一定的厚度，从而对电源罩32起到支撑作用。在LED灯具高度方向上，加强筋3212的高度不高于电源罩32的高度。从LED灯具高度方向的截面上看，加强筋3212设置于电源罩32内部，且无露出于电源罩32的部分，从而在高度上，不增加电源罩32相对底座1的高度。Seen from the cross-section of the LED lamp in the height direction, a part of the power cover 32 is located above the recess 12 of the base 1 , and a part is located in the recess 12 of the base 1 . The power supply cover 32 may include a support part 321 for support. The supporting portion 321 is partially disposed in the concave portion 12 for supporting the center of the power supply cover 32 .

Further, the support part 321 may include one or more support reinforcement members 3211 . The support reinforcement member 3211 is located on the peripheral side of the support portion 321 and plays a role in strengthening the support strength of the support portion 321 . The supporting part 321 may further include one or more reinforcing ribs 3212 . The reinforcing rib 3212 extends from the support portion 321 toward the edge of the power supply cover 32 and has a certain thickness, so as to support the power supply cover 32 . In the height direction of the LED lamp, the height of the reinforcing rib 3212 is not higher than the height of the power cover 32 . Seen from the cross-section of the LED lamp in the height direction, the ribs 3212 are disposed inside the power supply cover 32 , and no part is exposed from the power supply cover 32 , so that the height of the power supply cover 32 relative to the base 1 is not increased in height.

如图18、19所示，电源罩32的中心用于容置引挂器5的周侧，可以包括一个或多个安装部329。安装部329在LED灯具的高度方向上，朝向安装面方向凸起。安装部329朝向安装面方向凸起的面与底座1可接触或不接触。安装部329朝向安装面方向凸起的面与底座1接触时，电源罩32与底座1的连接，可提高其连接的稳定性。安装部329朝向安装面方向凸起的面可不与底座1接触，从而减少电源罩32的材料，进而降低成本。本实施例中采用安装部329朝向安装面方向凸起的面与底座1部分接触的形式。本实施例中，包括两个安装部329，两个安装部329对向设置。两个安装部329分别包括一用于螺丝穿过的孔洞，从而使电源罩32与底座1可通过螺丝固定连接。安装部329的边缘部可采用倒角和/或斜面设置，在安装过程中，使安装者不易被安装部329边缘划伤，从而能提高在安装过程中的安全性。As shown in FIGS. 18 and 19 , the center of the power supply cover 32 is used to accommodate the peripheral side of the hanger 5 , and may include one or more installation parts 329 . The installation portion 329 protrudes toward the installation surface in the height direction of the LED lamp. The protruding surface of the mounting portion 329 toward the mounting surface may or may not be in contact with the base 1 . When the protruding surface of the mounting portion 329 toward the mounting surface contacts the base 1 , the connection between the power cover 32 and the base 1 can improve the stability of the connection. The protruding surface of the mounting portion 329 toward the mounting surface may not be in contact with the base 1 , thereby reducing the material of the power supply cover 32 and further reducing the cost. In this embodiment, a form is adopted in which the surface of the mounting portion 329 protruding toward the mounting surface is in contact with part of the base 1 . In this embodiment, it includes two installation parts 329, and the two installation parts 329 are oppositely arranged. The two mounting parts 329 each include a hole for a screw to pass through, so that the power supply cover 32 and the base 1 can be fixedly connected by screws. The edge of the installation part 329 can be chamfered and/or beveled, so that the installer is not easily scratched by the edge of the installation part 329 during the installation process, thereby improving the safety during the installation process.

电源罩32露出于底座1的凹部12的部分对光源部2射出的光具有反射作用。电源罩32的可采用反射性能较好的材质，如金属材质、塑料材质等。另外，为提高电源罩32的反射，电源罩32可采用白色的材质，以提高反射效果。电源罩32对朝向LED灯具中心发光的第一光源组件21所发出的光，具有反射作用。第一光源组件21发出的光，至少部分直接照射至电源罩32上，之后通过电源罩32的反射作用，从灯罩4射出。The portion of the power supply cover 32 exposed from the concave portion 12 of the base 1 has a reflective effect on the light emitted from the light source unit 2 . The power supply cover 32 can be made of a material with better reflection performance, such as metal material, plastic material and the like. In addition, in order to improve the reflection of the power supply cover 32, the power supply cover 32 can be made of white material to improve the reflection effect. The power cover 32 has a reflective effect on the light emitted by the first light source assembly 21 that emits light toward the center of the LED lamp. The light emitted by the first light source assembly 21 is at least partially irradiated onto the power supply cover 32 , and then emitted from the lamp cover 4 through the reflection of the power supply cover 32 .

电源罩32露出于底座1的凹部12的部分可为环形或大致环形。为减少因电源罩32遮当而导致光经电源罩32反射后射出的光，电源罩32亦可呈两侧为弧边斜面、两侧为直边斜面的形状。同理，电源罩32亦可呈四边为直边斜面/多边为直边斜面形状。The portion of the power supply cover 32 exposed from the concave portion 12 of the base 1 may be annular or substantially annular. In order to reduce the light reflected by the power cover 32 due to the cover of the power supply cover 32, the power supply cover 32 can also be in the shape of arc-edged slopes on both sides and straight-sided slopes on both sides. In the same way, the power supply cover 32 can also be in the shape of four sides being straight-sided slopes/multiple sides being straight-side slopes.

如图7~8、10~11所示，光源支撑部11还可包括一个或多个灯板限位单元113，第一灯板210和第二灯板220可分别包括一个或多个灯板限位槽201，通过灯板限位单元113和灯板限位槽201的相互作用，分别使第一灯板210和第二灯板220不易发生移位，从而使第一灯板210和第二灯板220与底座1的连接更加稳定。在LED灯具的高度方向上，灯板限位单元113位于光源支撑部11的下部，呈一突起；灯板限位槽201可位于第一灯板210和/或第二灯板220的下部。灯板限位单元113与灯板限位槽201对应设置。在固定灯板时，将第一灯板210置于第一面111上，灯板限位单元113设置于灯板限位槽201内；第二灯板220置于第二面112上时，灯板限位单元113亦设置于灯板限位槽201内。本实施例中，每个光源支撑部11的第一面111上包括2个灯板限位单元113，且第二面112上包括2个灯板限位单元113，每个第一灯板210和第二灯板220包括2个与之对应的灯板限位槽201。As shown in Figures 7~8, 10~11, the light source support part 11 may further include one or more lamp panel limiting units 113, the first lamp panel 210 and the second lamp panel 220 may respectively include one or more lamp panel limiting grooves 201, through the interaction between the lamp panel limiting units 113 and the lamp panel limiting grooves 201, the first lamp panel 210 and the second lamp panel 220 are not easy to be displaced respectively, so that the connection between the first lamp panel 210 and the second lamp panel 220 and the base 1 is more stable . In the height direction of the LED lamp, the lamp panel limiting unit 113 is located at the lower part of the light source support part 11 and is a protrusion; the lamp panel limiting groove 201 can be located at the lower part of the first lamp panel 210 and/or the second lamp panel 220 .

The light source cover 24 can be made of transparent PC material to reduce light loss; it can also add light diffusing powder and other materials that can play a light diffusing effect, so that the light output is softer. The shape of the light source cover 24 can be an integrated structure matching the whole of the light source support part 11 . And because the light source cover 24 is a whole, the assembly is more convenient. In other embodiments (not shown in the figure), the LED lamp may include a plurality of light source covers 24 , and the plurality of light source covers 24 may be respectively provided on the first light source assembly 21 and the second light source assembly 22 . The light source cover 24 may include a base fixing member 241 . Specifically, the base fixing member 241 is disposed at a position relative to the joint of the first lamp board 210 , that is, at a turning point corresponding to the light source cover 24 and the light source support portion 11 . The base fixing member 241 is used to connect and fix the base 1 . The base fixing member 241 can be directly connected with the base 1 , so as to connect and fix the light source cover 32 with the base 1 . Specifically, the base fixing member 241 and the base 1 can be connected by bolt locking, buckle connection, snap connection and other connection methods. The base fixing member 241 may be located on the outer peripheral side of the light source cover 24 and/or on the inner peripheral side of the light source cover 24 . The base fixing member 241 can be attached to the base 1 to increase the contact area, thereby making the fixing more stable. The base fixing member 241 may not be in direct contact with the base 1 , that is, other intermediate members may be arranged between the base fixing member 241 and the base 1 .

如图1~2、10~11所示，底座1可包括用于与灯罩4连接的灯罩连接部15。底座固定构件241可与灯罩连接部15连接，且不直接与底座1接触。灯罩连接部15被固定在底座固定构件241与底座1之间。底座固定构件241、灯罩连接部15以及底座1可通过螺栓锁紧、卡扣连接、卡合连接等连接方式进行连接。于其他实施例中（图未示），底座固定构件241可设置在底座1与灯罩连接部15之间，底座固定构件241可分别与底座1以及灯罩连接部15相接触。As shown in FIGS. 1-2 and 10-11 , the base 1 may include a lampshade connecting portion 15 for connecting with the lampshade 4 . The base fixing member 241 can be connected with the lampshade connecting portion 15 and not directly contact with the base 1 .

如图5~6、10~11所示，为了固定第一灯板210/第二灯板220，光源罩24可包括一固定筋构件242。固定筋构件242设置于光源罩24朝向第一灯板210/第二灯板220的一侧。在将光源罩24通过光源固定构件241与底座1连接固定后，固定筋构件242压设于第一灯板210/第二灯板220之上，对第一灯板210/第二灯板220产生一定的压力，从而固定第一灯板210/第二灯板220。同时因为光源支撑部11的灯板限位单元113与第一灯板210/第二灯板220的灯板限位槽的限位作用，使第一灯板210/第二灯板220被限制在光源支撑部11与光源罩24之间。具体的，第一灯板210/第二灯板220设置于灯板限位单元113与固定筋构件242之间，第一灯板210/第二灯板220受到灯板限位单元113的支撑作用的同时，受到来自固定筋构件242的压力，从而使得第一灯板210/第二灯板220得以固定。固定筋构件242可设置在两个相邻的灯珠200之间，从而减少其对第一光源组件21和第二光源组件22的出光影响。进一步，从LED灯具的高度方向看，固定筋构件242不延伸至光源罩24的下部。即，光源罩24的下部不设置固定筋构件242。通过此设计，可以使固定筋构件242不会对第一灯板210/第二灯板220造成过度挤压。于其他实施例中（图未示），固定筋构件242亦可延伸至光源罩24的下部，即光源罩24至下部为止，都包含固定筋构件242。As shown in FIGS. 5-6 and 10-11 , in order to fix the first lamp panel 210 /the second lamp panel 220 , the light source cover 24 may include a fixing rib member 242 . The fixing rib member 242 is disposed on a side of the light source cover 24 facing the first lamp board 210 /the second lamp board 220 . After the light source cover 24 is connected and fixed to the base 1 through the light source fixing member 241, the fixing rib member 242 is pressed on the first lamp board 210/the second lamp board 220 to generate a certain pressure on the first lamp board 210/the second lamp board 220, thereby fixing the first lamp board 210/the second lamp board 220. At the same time, due to the limiting effect of the lamp panel limiting unit 113 of the light source supporting part 11 and the lamp panel limiting grooves of the first lamp panel 210 / the second lamp panel 220 , the first lamp panel 210 / the second lamp panel 220 is limited between the light source supporting part 11 and the light source cover 24 . Specifically, the first lamp panel 210/the second lamp panel 220 is arranged between the lamp panel limiting unit 113 and the fixing rib member 242, the first lamp panel 210/the second lamp panel 220 is supported by the lamp panel limiting unit 113, and at the same time receives the pressure from the fixing rib member 242, so that the first lamp panel 210/the second lamp panel 220 can be fixed. The fixing rib member 242 can be arranged between two adjacent lamp beads 200 , so as to reduce its influence on the light output of the first light source assembly 21 and the second light source assembly 22 . Further, viewed from the height direction of the LED lamp, the fixing rib member 242 does not extend to the lower part of the light source cover 24 . That is, the lower part of the light source cover 24 is not provided with the fixing rib member 242 . Through this design, the fixing rib member 242 will not cause excessive extrusion to the first lamp panel 210 /the second lamp panel 220 . In other embodiments (not shown), the fixing rib member 242 may also extend to the lower part of the light source cover 24 , that is, the light source cover 24 includes the fixing rib member 242 up to the lower part.

光源罩24还可进一步包括透镜结构（图未示），通过透镜的作用，调节第一光源组件21和第二光源组件22的出光角度。The light source cover 24 may further include a lens structure (not shown in the figure), through which the light output angles of the first light source assembly 21 and the second light source assembly 22 can be adjusted.

The power supply cover fixing part 322 can be connected with the base fixing member 241 and the base 1 through bolt locking, buckle connection, snap connection and other connection methods.

电源罩固定部322的设置位置可与加强筋3212相对应，即在每根加强筋3212的延伸处设置一个与之对应的电源罩固定部322，从而使电源罩32与底座1的连接更加稳定。The setting position of the power supply cover fixing part 322 can correspond to the reinforcing rib 3212, that is, a corresponding power supply cover fixing part 322 is provided at the extension of each reinforcing rib 3212, so that the connection between the power supply cover 32 and the base 1 is more stable.

为减少对第一光源组件21的出光的遮挡作用，电源罩固定部322可朝向第一灯板210的连接处设置，即朝向两个相邻光源支撑部11的连接部设置。从而减少电源罩固定部322的阻挡对第一光源组件21的出光造成的光损。In order to reduce the blocking effect on the output light of the first light source assembly 21 , the power supply cover fixing portion 322 can be arranged toward the connection of the first lamp board 210 , that is, toward the connection of two adjacent light source support portions 11 . In this way, the light loss caused by the blocking of the power cover fixing portion 322 to the output light of the first light source assembly 21 is reduced.

如图1~3、9~11所示，光源部2可进一步包括一作为辅助发光的辅助发光单元23。因电源板31设置在LED灯具整体相对中心的位置，为使得达到较好的出光效果，辅助发光单元23可设置于电源板31上，从而使光源设置在较为中心位置。并且因为辅助发光单元23设置在电源板31上，而非其他单独的灯板或者电路板，从而能简化电路排布。辅助发光单元23包括一个或多个用于发光的灯珠200。辅助发光单元23的灯珠200可采用与第一光源组件21和/或第二光源组件22的灯珠200相同或不同的色温，从而可以改变LED灯具的色温。本实施例中，辅助发光单元23发出的为暖光光源，从而使得在夜间，用户开启辅助发光单元23时，能减弱LED灯具对人眼造成的刺激作用。辅助发光单元23还可包括一信号接收器（图未示）。通过信号接收器，辅助发光单元23能接收到外部的无线信号。As shown in FIGS. 1 to 3 and 9 to 11 , the light source unit 2 may further include an auxiliary lighting unit 23 as an auxiliary lighting. Since the power board 31 is arranged at the relative center of the LED lamp, in order to achieve a better light output effect, the auxiliary light emitting unit 23 can be arranged on the power board 31 so that the light source is arranged at a relatively central position. And because the auxiliary lighting unit 23 is arranged on the power supply board 31 instead of other separate lamp boards or circuit boards, the circuit arrangement can be simplified. The auxiliary lighting unit 23 includes one or more lamp beads 200 for lighting. The lamp bead 200 of the auxiliary lighting unit 23 can adopt the same or different color temperature as the lamp bead 200 of the first light source assembly 21 and/or the second light source assembly 22, so that the color temperature of the LED lamp can be changed. In this embodiment, the auxiliary light-emitting unit 23 emits a warm light source, so that at night, when the user turns on the auxiliary light-emitting unit 23, the stimulating effect of the LED lamp on human eyes can be weakened. The auxiliary lighting unit 23 may also include a signal receiver (not shown). Through the signal receiver, the auxiliary lighting unit 23 can receive external wireless signals.

The light source cover 24 is arranged in conjunction with the light emitting unit 21 . The light source cover 24 can include a wiring portion 243 . The light emitting unit 21 is electrically connected to the power supply unit 3 through the wires of the connection unit 243 . The light source cover 24 can be transparent to reduce its absorption of light and reduce light loss; it is also possible to add diffusion powder to the material of the light source cover 24, or to arrange materials such as a diffusion coating on the light source cover 24 to adjust the light output and make the light output more uniform and soft.

于其他实施例中，发光单元21外侧可不设置光源罩或其他罩设物，从而减少因设置光源罩等而造成的光损。In other embodiments, no light source cover or other cover objects may be provided outside the light emitting unit 21 , so as to reduce the light loss caused by the installation of the light source cover and the like.

如图30、31、37、38所示，电源罩32上设置反射面，以反射发光单元21的至少一部分出光。电源罩32露出于底座1的凹部12外的部分形成所述反射面，以反射光源部2射出的光。电源罩32的可采用反射性能较好的材质，如金属材质、塑料材质等。另外，为提高电源罩32的反射，电源罩32可采用白色的材质，以提高反射效果。具体的，电源罩32对朝向LED灯具中心发光的发光单元21所发出的光，具有反射作用。第一光源组件21发出的光，至少部分直接照射至电源罩32上，之后通过电源罩32的反射作用，从灯罩4射出。As shown in FIGS. 30 , 31 , 37 , and 38 , a reflective surface is provided on the power cover 32 to reflect at least a part of the light emitting unit 21 to emit light. The portion of the power supply cover 32 exposed outside the concave portion 12 of the base 1 forms the reflective surface for reflecting the light emitted by the light source unit 2 . The power supply cover 32 can be made of a material with better reflection performance, such as metal material, plastic material and the like. In addition, in order to improve the reflection of the power supply cover 32, the power supply cover 32 can be made of white material to improve the reflection effect. Specifically, the power cover 32 has a reflective effect on the light emitted by the light emitting unit 21 that emits light toward the center of the LED lamp. The light emitted by the first light source assembly 21 is at least partially irradiated onto the power supply cover 32 , and then emitted from the lamp cover 4 through the reflection of the power supply cover 32 .

电源罩32露出于底座1的凹部12的部分可为环形或大致环形。为减少因电源罩32遮当而导致光经电源罩32反射后射出的光，电源罩32亦可呈两侧为弧边斜面、两侧为直边斜面形状。同理，电源罩32亦可呈四边为直边/多边为直边的斜面形状。本实施例中，电源罩露出于底座1的凹部12的部分可呈两侧为弧边斜面、两侧为直边斜面形状，从而能在确保电源板31容置在电源罩32内的同时，电源罩32露出于底座1的凹部12的部分的反射效果更好。The portion of the power supply cover 32 exposed from the concave portion 12 of the base 1 may be annular or substantially annular. In order to reduce light reflected by the power supply cover 32 due to the cover of the power supply cover 32 , the power supply cover 32 can also be in the shape of arc-edge slopes on both sides and straight-edge slopes on both sides. Similarly, the power supply cover 32 can also be in the shape of an inclined plane with four straight sides/multiple straight sides. In this embodiment, the portion of the power supply cover exposed to the concave portion 12 of the base 1 can be in the shape of arc-edge slopes on both sides and straight-edge slopes on both sides, so as to ensure that the power supply board 31 is accommodated in the power supply cover 32. At the same time, the reflection effect of the portion of the power supply cover 32 exposed to the concave portion 12 of the base 1 is better.

The light source module 11' is electrically connected to the power module 12'. The light source module 11' includes a first light source board 111'. The first light source board 111' emits light toward the mounting surface away from the LED lamp. The first light source board 111' may include a first light emitting unit 1111'. The first light emitting unit 1111' includes a lamp bead 100'. The lamp beads 100' are arranged on the first light source board 111', and the lamp beads 100' can be arranged in a ring shape. The first light emitting unit 1111' may include one or more rings of lamp beads 100' arranged in a ring. The distances between two adjacent lamp beads 100' on the same circle are the same or approximately the same. In this embodiment, three rings of lamp beads 100' are arranged in a ring shape.

第一发光单元1111’可包括半径不相同的多个虚拟的圆，灯珠100’分别排布在多个虚拟的圆的圆周上。多个虚拟的圆可具有共同的圆心，即，多个虚拟的圆为半径不相同的同心圆。位于同一个虚拟的圆上的相邻的两个灯珠100的距离可相同或大致相同，从而使得第一发光单元1111’发出的光均匀射出。本实施例中，包括3个虚拟圆。第一虚拟圆L1的半径为r1，第二虚拟圆L2的半径为r2，第三虚拟圆L3的半径为r3。第一虚拟圆L1和第二虚拟圆L2的半径差r1-r2与第二虚拟圆L2和第三虚拟圆L3半径差r2-r3，相同或大致相同，从而使得第一发光单元发出的光均匀射出。The first light emitting unit 1111' may include multiple virtual circles with different radii, and the lamp beads 100' are respectively arranged on the circumferences of the multiple virtual circles. Multiple virtual circles may have a common center, that is, multiple virtual circles are concentric circles with different radii. The distances between two adjacent lamp beads 100 located on the same virtual circle can be the same or approximately the same, so that the light emitted by the first light emitting unit 1111' can be evenly emitted. In this embodiment, three virtual circles are included. The radius of the first virtual circle L1 is r1, the radius of the second virtual circle L2 is r2, and the radius of the third virtual circle L3 is r3. The radius difference r1-r2 between the first virtual circle L1 and the second virtual circle L2 is the same or substantially the same as the radius difference r2-r3 between the second virtual circle L2 and the third virtual circle L3, so that the light emitted by the first light emitting unit is uniformly emitted.

于其他实施例中（图未示），灯珠100’可呈四边形或多个四边形的形式排布。In other embodiments (not shown in the figure), the lamp beads 100' can be arranged in the form of a quadrangle or a plurality of quadrangles.

The auxiliary light-emitting unit 1112' includes a lamp bead 101', and the lamp bead 101' can emit the same color temperature as the lamp bead 100', or can be a lamp bead that emits a different color temperature from the lamp bead 100'. The auxiliary light-emitting unit 1112' can be turned on independently when the first light-emitting unit 1111' is not turned on; it can also be turned on simultaneously with the first light-emitting unit 1111'.

第一光源板111’可固定于底座4’上。具体的，第一光源板111’可通过现有技术中的螺丝锁紧、胶粘、卡扣等方式进行连接固定。The first light source board 111' can be fixed on the base 4'. Specifically, the first light source board 111' can be connected and fixed by means of screw locking, gluing, buckling, etc. in the prior art.

光源模组11’可包括一第二光源板112’。第二光源板112’朝向背离LED灯具的安装面发光。第二光源板112’可设置于第一光源板111’的外侧。第二光源板112’包括第二发光单元1121’。第二发光单元1121’位于第一发光单元1111’的外侧，第二发光单元1121’相对第一发光单元1111’，位于更远离LED灯具的轴心的位置。因第二发光单元1121’位于相对远离LED灯具轴心的位置，可以照亮第一发光单元1111’外侧，使得LED灯具的照射范围更广。第二发光单元1121’包括灯珠102’，灯珠102’可为与灯珠100’发出同样色温的灯珠，亦可为与灯珠100’发出不同色温的灯珠。两个相邻的灯珠102’之间的距离可相同或大致相同，从而使得第二发光单元1121’发出的光均匀射出。The light source module 11' may include a second light source board 112'. The second light source board 112' emits light toward the mounting surface away from the LED lamp. The second light source board 112' can be disposed outside the first light source board 111'. The second light source board 112' includes a second light emitting unit 1121'. The second light emitting unit 1121' is located outside the first light emitting unit 1111', and the second light emitting unit 1121' is located farther from the axis of the LED lamp than the first light emitting unit 1111'. Since the second light emitting unit 1121' is located relatively away from the axis of the LED lamp, it can illuminate the outside of the first light emitting unit 1111', so that the LED lamp can illuminate a wider range. The second light emitting unit 1121' includes a lamp bead 102', and the lamp bead 102' can be a lamp bead emitting the same color temperature as the lamp bead 100', or can be a lamp bead emitting a different color temperature from the lamp bead 100'. The distance between two adjacent lamp beads 102' can be the same or approximately the same, so that the light emitted by the second light emitting unit 1121' can be evenly emitted.

第二光源板112’可固定于底座4’上。具体的，第二光源板112’可通过螺丝锁紧、胶粘等方式进行连接固定。The second light source board 112' can be fixed on the base 4'. Specifically, the second light source board 112' can be connected and fixed by means of screw locking, gluing and the like.

如图40、41、59所示，光源模组11’可包括一第三光源板113’。第三光源板113’朝向LED灯具的安装面的方向发光，从而可使安装面不产生暗区，进而使得空间的照明效果更佳。第三光源板113’可设置于底座4’上，进一步，第三光源板113’可设置于底座4’上与第一光源板111和第二光源板112相反的一侧。第三光源板113’可通过螺丝锁紧、胶粘等方式进行连接固定。As shown in Figures 40, 41 and 59, the light source module 11' may include a third light source board 113'. The third light source plate 113' emits light toward the installation surface of the LED lamp, so that no dark areas are generated on the installation surface, and the lighting effect of the space is improved. The third light source board 113' can be arranged on the base 4', further, the third light source board 113' can be arranged on the opposite side of the first light source board 111 and the second light source board 112 on the base 4'. The third light source board 113' can be connected and fixed by means of screw locking, gluing and the like.

第三发光板113’包括第三发光单元1131’。具体的，第三发光单元1131’朝向一反射面31’发光。第三发光单元1131’发出的光经过反射面31’的反射后，射出。反射面31’可为一平面，亦可为一曲面。当反射面31’为曲面时，能扩大第三发光单元1131’发出的光的角度。The third light emitting panel 113' includes a third light emitting unit 1131'. Specifically, the third light emitting unit 1131' emits light toward a reflective surface 31'. The light emitted by the third light emitting unit 1131' is reflected by the reflective surface 31' and then emitted. The reflective surface 31' can be a plane or a curved surface. When the reflective surface 31' is a curved surface, the angle of light emitted by the third light emitting unit 1131' can be enlarged.

反射面31’可位于灯体3’上。具体的，反射面31’可为灯体3’背离LED安装面的一侧的面。为使反射面31’的反射效果更好，第三光源板113’可设置在底座4’上相对较外侧的位置，且灯体3’的直径可大于底座4’的直径，即灯体3’的截面面积大于底座4的截面面积，从而增加反射面面积。The reflective surface 31' can be located on the lamp body 3'. Specifically, the reflective surface 31' may be the surface of the lamp body 3' on the side away from the LED mounting surface. In order to make the reflection effect of the reflective surface 31' better, the third light source plate 113' can be arranged at a relatively outer position on the base 4', and the diameter of the lamp body 3' can be larger than the diameter of the base 4', that is, the cross-sectional area of the lamp body 3' is larger than the cross-sectional area of the base 4, thereby increasing the reflective surface area.

第三发光单元1131’上包括灯珠103’，灯珠103’可为与灯珠100’发出同样色温的灯珠，亦可为与灯珠100’发出不同色温的灯珠。两个相邻的灯珠103’之间的距离可相同或大致相同，从而使得第三发光单元1131’发出的光均匀射出。The third light-emitting unit 1131' includes a lamp bead 103', and the lamp bead 103' can emit the same color temperature as the lamp bead 100', or can be a lamp bead that emits a different color temperature from the lamp bead 100'. The distance between two adjacent lamp beads 103' can be the same or approximately the same, so that the light emitted by the third light emitting unit 1131' can be evenly emitted.

如图40~42、45所示，光电模组1’包括一电源模组12’。电源模组12’可与光源模组11’为分体的结构，从而能起到更好的散热效果，不易让光源模组11’的散发的热量对电源模组12’产生影响，从而影响电源模组12’上元件的寿命。电源模组12’亦可与光源模组11’为一体的结构，从而能节约材料成本、简化组装工序。电源模组12’可包括电源板121。电源板121’可与光源板一体或分体设置。本实施例中，电源板121’与第一光源板111’为一体式结构。电源板121’的电源元件1211’可安装在与灯珠100’相同的一侧，从而减少LED灯具的内部空间，进一步减少LED灯具的整灯高度。电源板121’的电源元件1211亦可安装在与灯珠100’的相反侧，从而能减弱灯珠100’散发的热对电源元件产生的影响。电源板121’的电源元件1211’亦可部分安装在与灯珠100’相同的一侧，部分安装在与灯珠100’相反的一侧，从而可以在控制电源元件1211’排布的同时，有效的控制灯珠100’散发的热对电源元件产生的影响。As shown in Figures 40-42 and 45, the photoelectric module 1' includes a power module 12'. The power supply module 12' can be separated from the light source module 11', so as to achieve a better heat dissipation effect, and it is difficult for the heat emitted by the light source module 11' to affect the power supply module 12', thereby affecting the life of the components on the power supply module 12'. The power supply module 12' can also be integrated with the light source module 11', thereby saving material costs and simplifying the assembly process. The power module 12' can include a power board 121. The power supply board 121' can be integrated or separated from the light source board. In this embodiment, the power supply board 121' is integrated with the first light source board 111'. The power element 1211' of the power board 121' can be installed on the same side as the lamp bead 100', thereby reducing the internal space of the LED lamp and further reducing the overall lamp height of the LED lamp. The power element 1211 of the power board 121' can also be installed on the opposite side of the lamp bead 100', so as to reduce the influence of the heat emitted by the lamp bead 100' on the power element. The power supply element 1211' of the power supply board 121' can also be partially installed on the same side as the lamp bead 100', and partially installed on the opposite side to the lamp bead 100', so that while controlling the arrangement of the power supply element 1211', it can effectively control the influence of the heat emitted by the lamp bead 100' on the power supply element.

如图40、41所示，光源罩2可包括第一光源罩21’。第一光源罩21’罩设在第一光源板111’以及第二光源板112’的出光侧，第一发光单元1111’以及第二发光单元1121’发出的光，经过第一光源罩21’射出。第一光源罩21’可包含扩散粉等能使光扩散的材质构成，从而能使LED灯具的出光更加均匀。第一光源罩21’可包括第一防脱落构件（图未示），通过第一防脱落构件的作用，使第一光源罩21’与底座连接固定。As shown in Figures 40 and 41, the light source cover 2 may include a first light source cover 21'. The first light source cover 21' is located on the light emitting side of the first light source board 111' and the second light source board 112', and the light emitted by the first light emitting unit 1111' and the second light emitting unit 1121' is emitted through the first light source cover 21'. The first light source cover 21' can be made of a material capable of diffusing light, such as diffusing powder, so as to make the light output of the LED lamp more uniform. The first light source cover 21' may include a first fall-off preventing member (not shown in the figure), through the function of the first fall-off preventing member, the first light source cover 21' is connected and fixed to the base.

如图40、41、46、47、53、54所示，光源罩2’还可包括一第二光源罩22’。第二光源罩22’罩设在第三光源板113’的出光侧，第三发光单元1131’射出的光经过第二光源罩22’后，射出。通过设置第二光源罩22’，能防止第三光源板113’直接裸露在外，从而能提高LED灯具的安全性。As shown in Figures 40, 41, 46, 47, 53, and 54, the light source cover 2' may further include a second light source cover 22'. The second light source cover 22' is disposed on the light emitting side of the third light source board 113', and the light emitted by the third light emitting unit 1131' passes through the second light source cover 22' before being emitted. By providing the second light source cover 22', the third light source plate 113' can be prevented from being directly exposed, thereby improving the safety of the LED lamp.

第二光源罩22’可包括一灯体固定结构221，通过固定构件221’的连接固定作用，使第二光源罩22’与底座4’连接固定。具体的，固定构件221’可为一孔洞，并在底座4’上设置想对应的孔洞，通过螺丝/螺栓等连接构件的连接，将第二光源罩22’与底座4’进行连接固定。The second light source cover 22' may include a lamp body fixing structure 221, and the second light source cover 22' is connected and fixed to the base 4' through the connecting and fixing function of the fixing member 221'. Specifically, the fixing member 221' can be a hole, and a corresponding hole is provided on the base 4', and the second light source cover 22' is connected and fixed to the base 4' through the connection of connecting members such as screws/bolts.

第二光源罩22’可包括灯体限位构件222’。通过灯体限位构件222’的作用，第二光源罩22’与底座4’在安装时，更为简便的确定相对位置，从而进行连接固定。进一步，底座4’可包括一用于与灯体限位构件222’配合作用的第二防脱落构件33’。具体的，灯体限位构件222’可为一朝向第二防脱落构件33’的延伸部，第二防脱落构件33’可为一容置槽，灯体限位构件222’卡入第二防脱落构件33’内，使灯体3’与第二光源罩22’确定相对位置。第二防脱落构件33’还可包括一限位构件331’，通过限位构件331’的限位作用，限制第二光学罩22’的位置。具体的，限位构件331’可朝向第二光源罩22’凸起。The second light source cover 22' may include a lamp body limiting member 222'. Through the function of the lamp body limiting member 222', the relative position of the second light source cover 22' and the base 4' can be more easily determined during installation, so as to be connected and fixed. Further, the base 4' may include a second fall-off preventing member 33' for cooperating with the lamp body limiting member 222'. Specifically, the lamp body limiting member 222' can be an extension toward the second anti-falling member 33', the second anti-falling member 33' can be a receiving groove, and the lamp body limiting member 222' snaps into the second anti-falling member 33', so that the relative position of the lamp body 3' and the second light source cover 22' is determined. The second anti-dropping member 33' can also include a limiting member 331', and the position of the second optical cover 22' is limited by the limiting function of the limiting member 331'. Specifically, the limiting member 331' can protrude toward the second light source cover 22'.

于其他实施例中，第二光源罩22’还可包括透镜结构，以改变从第三光源部113’发出的光的出射角度，从而调节从经过反射面31’发射出的光的出光角度。具体的，透镜结构可以在靠近LED灯具外侧的部分的壁厚大于靠近LED灯具轴心的部分壁厚的状态，从而使光更多的出射至反光面31’上，经过反光面的反射后，射出。In other embodiments, the second light source cover 22' may further include a lens structure to change the exit angle of the light emitted from the third light source part 113', thereby adjusting the exit angle of the light emitted through the reflective surface 31'. Specifically, the lens structure can be in a state where the wall thickness of the part near the outer side of the LED lamp is greater than the wall thickness of the part near the axis of the LED lamp, so that more light is emitted to the reflective surface 31', and then emitted after being reflected by the reflective surface.

第一发光单元1111’、辅助发光单元1112’、第二发光单元1121’、第三发光单元1131’可同时点亮或者分别点亮，即可以以组合的形式点亮。包括但不限于，例如，第一发光单元1111’可与辅助发光单元1112’同时点亮，而第二发光单元1121’、第三发光单元1131’不发生点亮；辅助发光单元1112’可与第二发光单元1121’同时点亮，而第一发光单元1111’、第三发光单元1131’不发生点亮；亦或其他任意组合形式点亮。使用者可根据需求，通过多种出光点亮方式，调节出光亮度，改变LED灯具出光照射范围。The first light-emitting unit 1111', the auxiliary light-emitting unit 1112', the second light-emitting unit 1121', and the third light-emitting unit 1131' can be turned on simultaneously or separately, that is, they can be turned on in combination. Including but not limited to, for example, the first light-emitting unit 1111' and the auxiliary light-emitting unit 1112' can be turned on at the same time, while the second light-emitting unit 1121' and the third light-emitting unit 1131' are not turned on; Users can adjust the light brightness and change the light irradiation range of LED lamps through a variety of light lighting methods according to needs.

位于第二基板220上的第二发光单元224包括多个LED灯珠202，第二光源组件22的LED灯珠202的数量大于第一光源组件21的LED灯珠202的数量，因为第二光源组件22是贴覆在底座1的承载部13（如下所述）上，第二光源组件22产生的热量可传递至承载部13，而第一光源组件21没有可直接接触的热传导介质，通过此种设置不易使第一光源组件21上的热量在第一基板212处集聚。The second light-emitting unit 224 on the second substrate 220 includes a plurality of LED lamp beads 202. The number of LED lamp beads 202 of the second light source assembly 22 is greater than the number of LED lamp beads 202 of the first light source assembly 21, because the second light source assembly 22 is attached to the bearing portion 13 (described below) of the base 1, the heat generated by the second light source assembly 22 can be transferred to the bearing portion 13, and the first light source assembly 21 has no heat transfer medium that can be directly contacted.
