Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

The embodiment of the application discloses a lamp, which is shown in figures 1 to 10, and comprises a center pillar 1, a plurality of connecting pieces 2 and a lamp cap 3. The center column 1 is a central structure of the lamp, and the center column 1 extends along the vertical direction, so that the whole lamp has a larger depth dimension in the vertical direction, and the whole shape is more three-dimensional. On the center pillar 1 there is a first light emitting part 10 and a first connecting part 12, and in some embodiments there may also be a second light emitting part 11, the first light emitting part 10 extending in a vertical direction for enabling a majority of the lateral area of the center pillar 1 to emit illumination light, the second light emitting part 11 being located at the bottom of the center pillar 1 for enabling the bottom of the center pillar 1 to emit illumination light.

Specifically, the first light emitting portion 10 includes a first light source module 100 and a first light guide member 101, and light emitted by the first light source module 100 is dispersed and emitted by the first light guide member 101, so that a user can observe that the whole first light guide member 101 uniformly emits light without obvious light emitting points when observing the first light guide member 101 from the outside. When the lamp further has the second light emitting portion 11, the second light emitting portion 11 includes the second light source module 110 and the second light guide 111, and the light emitted by the second light source module 110 is dispersed and emitted by the second light guide 111, so that the second light guide 111 uniformly emits light as a whole. The provision of the first light-emitting portion 10 and the second light-emitting portion 11 enables the center pillar 1 as a whole to form a three-dimensional light-emitting region.

The lamp cap 3 is connected with the first connecting part 12 of the center pillar 1 through the connecting piece 2, so that the lamp cap 3 and the center pillar 1 form a whole, and the lamp can integrally form various shapes through changing the shapes and arrangement of the center pillar 1, the connecting piece 2 and the lamp cap 3. The third light source module 30 and the third light guide member 31 are included in the lamp cap 3, and the light emitted by the third light source module 30 is dispersed and emitted by the third light guide member 31, so that the lamp cap also forms a uniform light emitting area.

The lamp disclosed by the embodiment of the application can present a three-dimensional appearance similar to a pendant lamp through the cooperation of the center post 1, the connecting piece 2 and the lamp cap 3. Meanwhile, the lamp of the embodiment does not utilize a common bulb for illumination, but is provided with different illumination structures on the center pillar 1 and the lamp cap 3 respectively. The lighting structures are not of a dead plate single shape of the lamp, but can be designed into a more attractive shape according to the needs, so that the lamp provided by the embodiment effectively avoids negative influence on the overall attractive performance of the lamp caused by adopting the lamp, and the attractive performance of the lamp is greatly improved.

In order to form a uniform light emitting effect, the lamp caps 3 may be arranged around the central column 1 at intervals in general, and in order to increase the light emitting area, the third light guide member 31 may be a light guide plate, where the light guide plate has two main light emitting surfaces (i.e., the surface with the largest area on the light guide plate is not numbered in the drawing) that are away from each other, one of the main light emitting surfaces faces the central column 1, and the other main light emitting surface can be away from the central column 1, so as to emit light in a direction away from the central column 1.

In the embodiment of the present application, the first light source module 100, the second light source module 110 and the third light source module 30 may all use small light sources such as LED light emitting units as light emitting elements, and the small light sources are easy to be arranged, so as to adapt to more complex lamp structures.

The center pillar 1 in this embodiment will be described in detail.

As shown in fig. 2 to 5, the center pillar 1 in this embodiment includes, in addition to the first light emitting portion 10, the second light emitting portion 11, and the first connecting portion 12, an upper seat 13, a middle seat 14, and a base 15, where the upper seat 13, the middle seat 14, and the base 15 are sequentially arranged from top to bottom, and the first light emitting portion 10 is fixed by the upper seat 13 and the middle seat 14.

Specifically, a middle rod 16 may be disposed in the middle column 1, and the upper seat 13 and the middle seat 14 may be positioned by the middle rod 16. The middle rod 16 is connected to the middle seat 14 by the upper seat 13, and in this embodiment, the middle rod 16 passes through the upper seat 13 and the middle seat 14, and the middle seat 14 is supported from below by a clamping member 160 provided on the middle rod 16. The first light emitting part 10 is disposed around the middle rod 16 between the upper seat 13 and the middle seat 14 to hide the middle rod 16, and the upper seat 13 is lifted by the first light emitting part 10 to prevent the upper seat 13 from falling down. In addition to this, the intermediate lever 16 and the upper and middle seats 13, 14 may be directly fastened by screw connection or other means.

The top end of the middle rod 16 can also directly pass through the upper seat 13 from below, and a hanging chain nut 18 can be arranged above the upper seat 13 to be connected with the middle rod 16. The lamp can be suspended in the room by arranging the chassis 4 on the ceiling and hanging the hanging chain 5 to hang the hanging chain nut 18 during installation. The chassis 4 can be internally provided with a driving module of the lamp, and can be additionally provided with a color temperature control or intelligent control module which can be controlled by consumers in a wired or wireless mode, so that the lamp has a richer lighting effect.

The middle rod 16 and the connecting piece 2 can be designed into hollow tubular structures, the power line falls down from the chassis 4 along the hanging chain 5 and enters the middle rod 16, and the power line can be divided into a plurality of strands to be respectively connected with the first light source module 100 and the second light source module 110 after extending into the middle seat 15 along the middle rod 16 or penetrating through the connecting piece 2 and being connected with the lamp cap 3.

An independent wire can be arranged inside the connecting piece 2, plug connectors are respectively arranged at two ends of the wire, and the wire can be electrically connected with a circuit arranged in the middle seat 15 and the lamp cap 3 through the plug connectors. Alternatively, the present embodiment may also consider an integrated structure of the structural connection and the electrical connection.

In the present embodiment, the first light source module 100 may be disposed on the middle base 14, and the first light guide 101 is opposite to the first light source module 100 and extends from the middle base 14 to the upper base 13. Thus, the first light source module 100 can emit light upwards, so that the user can be prevented from directly observing the first light source module 100, and the glare is avoided.

A mounting groove 140 may be provided on the center base 14, the first light source module 100 may be provided in the mounting groove 140, and a pressing cover 17 may be provided in the center pillar 1 to close the mounting groove 140 in order to prevent intrusion of external moisture.

The first light emitting portion 10 may include a plurality of sets of first light source modules 100 and first light guide members 101, where the plurality of sets of first light source modules 100 may be uniformly distributed around the middle rod 16 along the circumferential direction and radially extend with the middle rod 16 as a center, that is, the LED light emitting units on the first light source modules 100 are sequentially far from the middle rod 16 along the radial direction. Meanwhile, the first light guide members 101 are also uniformly distributed around the middle rod 16 along the circumferential direction, and each first light source module 100 is correspondingly matched with one first light guide member 101. In general, the first light guide 101 employs a light guide plate having a uniform thickness, and if the first light guide 101 employs a cylindrical structure surrounding the center pole 16, the shape that can be exhibited is very limited due to the thickness limitation. However, since the outer contour of the first light emitting portion 10 can be defined by the main planar shape of the first light guide 101 in the above-described manner, the outer contour of the first light emitting portion 10 can be adjusted by changing the main planar shape while maintaining the thickness of the light guide plate, so that a more complicated outer structure can be formed, and the appearance performance can be improved. For example, the main plane shown in fig. 4 has a gradual shape with a size in the radial direction that is smaller and larger, so that the overall outer contour of the first light emitting portion 10 is shaped like a jade bottle.

The number of the first light source modules 100 and the first light guide members 101 in the first light emitting portion 10 may be designed according to needs, and a typical lamp may employ three, four or five sets of the first light source modules 100 and the first light guide members 101. The arrangement of the plurality of first light source modules 100 and the first light guide members 101 may be freely selected, for example, may be equally spaced around the middle rod 16, or may be arranged in groups of two or more complex arrangements.

In the first light emitting portion 10 provided in this embodiment, a binding 102 may be wrapped on a side of each first light guiding member 101 facing away from the middle rod 16, and two ends of the binding 102 are respectively connected with the upper seat 13 and the middle seat 14. The first light guide 101 can be effectively protected by the edge covering, and foreign objects are prevented from being knocked. In addition, the edge cover made of the non-transparent material has a shading effect, so that the outer contour of the first light-emitting part 10 is clearer.

As shown in fig. 2 to 4, the first connecting portion 12 in the present embodiment is fixed by the middle seat 14 and the base 15 in cooperation. Specifically, the middle seat 14 and the base 15 may together form a circle of mounting openings 150, and each mounting opening 150 has a first connecting portion 12 embedded therein. In other embodiments, the middle seat 14 and the base 15 may also form other structures capable of cooperatively fixing the first connecting portion 12. These first connecting portions 12 may be provided independently of each other or may be integrated. In order to facilitate the connection of the connection member 2, the first connection portion 12 may employ a flexible bush on which a connection hole 120 is provided to be matched with the connection member 2, and one end of the connection member 2 may be inserted into the connection hole 120 to achieve the connection with the center pillar 1 (see fig. 6). In this embodiment, the first connection portion 12 inside the center pillar 1 can be matched and replaced according to the shape of the connection member 2, so that the center pillar 1 can be matched with various connection members 2 and the lamp cap 3, and the universality is good.

The connection of the connecting piece 2 to the first connecting portion 12 by means of plugging is very quick but not reliable enough. In order to prevent the connection member 2 from coming out of the first connection portion 12, a first perforation 121 may be provided on each flexible sleeve, a second perforation 141 may be provided on the intermediate seat 14 in correspondence of the first perforation 121, and a third perforation 20 (see fig. 7) may be provided on the connection member 2. When the connector 2 is inserted into the connecting hole 120, the first through hole 121, the second through hole 141, and the third through hole 20 are aligned. The center pillar 1 may further include a first mounting member 19 therein, the first mounting member 19 passing through the first through hole 121, the second through hole 141 and the third through hole 20 and restricting movement of the connecting member 2 with respect to the center pillar 1. The third through hole 20 may be a screw hole, and the first attachment 19 made of a screw can have a more excellent limiting effect.

As shown in fig. 4 and 5, the second light emitting portion 11 in the present embodiment is fixed below the base 15. Specifically, the second light source module 110 includes a plurality of second light emitting units 110a, the second light emitting units 110a are arranged in an annular shape, and the second light guide 111 is located inside an area surrounded by the annular shape. The light emitted by the second light emitting unit 110a transversely enters the second light guide 111, and is uniformly dispersed by the second light guide 111. The design mode can enable the bottom of the center column 1 to form an integrated light-emitting structure, and is beneficial to improving the light uniformity.

In general, the second light emitting unit 110a should be disposed opposite to the second light guide 111, i.e., toward the inside of the ring shape. However, such an arrangement requires that the second light emitting unit 110a be disposed on the annular substrate surrounding the second light guide 111, which is difficult to manufacture and assemble. In order to simplify the assembly difficulty, the second light emitting units 110a are disposed downward in the present embodiment, rather than toward the inner side of the ring shape, so that all the second light emitting units 110a may be uniformly disposed on the lower surface of one circular light source substrate 110 b.

At this time, since the light emitting direction of the second light emitting unit 110a is substantially downward, most of the light cannot be directly irradiated into the second light guide 111. For this reason, the second light emitting portion 11 of the present embodiment may further include a reflecting portion 112, where the reflecting portion 112 surrounds the periphery of the second light emitting unit 110a and is connected to the base 15, and the reflecting portion 112 can reflect the light emitted by the second light emitting unit 110a toward the second light guide 111, so as to increase the light energy entering the second light guide 111.

In this embodiment, in order to make the bottom of the center pillar 1 more attractive and softer, the lamp shade 113 can be further disposed in the second light emitting portion 11, the lamp shade 113 covers the second light guiding member 111 from below the second light guiding member 111, and the edge of the lamp shade 113 abuts against the second light guiding member 111 from below, so that the light emitted by the second light guiding member 111 needs to pass through the lamp shade 113 to be irradiated to the outside, and the lamp shade 113 can distribute light on one hand and also has a good decorative effect on the other hand. Meanwhile, the reflecting portion 112 is sleeved on the periphery of the lamp housing 113, and lifts the edge of the lamp housing 113 from below to fix the lamp housing 113. When the lampshade 113 is required to be disassembled, the reflecting part 112 is only required to be disassembled, and the operation is very simple and convenient.

Further, a hanging buckle drop 114 may be further disposed in the second light emitting portion 11, the hanging buckle drop 114 may pass through the middle portion of the lampshade 113 and be fixedly connected with the base 15, the hanging buckle drop 114 may play a role in decoration, and on the other hand, the lampshade 113 may be lifted from the lower portion, so as to further improve the firmness of the lampshade 113.

As shown in fig. 7 to 10, the lamp cap 3 in this embodiment may include a housing 32 and a cover plate 33, where the housing 32 and the cover plate 33 together define a mounting cavity 34, and the housing 32 forms a main structure of the mounting cavity 34, and the cover plate 33 is mainly used to close an opening of the mounting cavity 34. The third light source module 30 is disposed in the mounting cavity 34, and for example, a clamping groove 320 may be formed in the mounting cavity 34 by the housing 32 to fix the third light source module 30.

A portion of the third light guide 31 is fixed in the mounting cavity 34 and is opposite to the third light source module 30, and the rest of the third light guide 31 protrudes from the mounting cavity 34 as an illumination area of the lamp cap 3. In the present embodiment, a fixing hole 310 may be provided at a portion of the third light guide 31 fixed in the mounting cavity 34, and a fixing post 321 may be provided at the housing 32 corresponding to the fixing hole 310, the fixing post 321 passing through the fixing hole 310, thereby restricting radial movement of the third light guide 31 with respect to the fixing post 321. The cover plate 33 is fixedly connected with the housing 32 through the fixing post 321, and seals the free end of the fixing post 321, so that the third light guide 31 cannot axially separate from the fixing post 321. The cover plate 33 and the fixing post 321 may be directly connected by a fastening means, or the fixing post 321 may be provided with a mounting hole 321a such as a fastening hole or a threaded hole, and then connected and fixed by a third mounting member 38 such as a fastener or a screw.

The overall appearance of the lamp cap 3 is basically determined by the housing 32 and the third light guide member 31, so that the overall appearance of the lamp cap 3 can be made to have different appearance configurations by adjusting the appearance of the housing 32 and the third light guide member 31 according to the overall style requirement of the lamp, for example, the third light guide member 31 in the embodiment can adopt an arc-shaped light guide plate, so that the lamp cap 3 is in a circular sector shape as a whole.

In addition, a decorative sheet 39 may be provided in the base 3, and the decorative sheet 39 at least partially covers the housing 32, thereby beautifying the housing 32. And the decorative sheet 39 forms a detachable connection structure with the housing 32 and/or the third light guide 31, so that the replacement is convenient, and the universality of the product is improved. The decorative sheet 39 and the housing 32 or the third light guide 31 may be detachably connected by a snap connection or the like.

In this embodiment, the connector 2 is connected to the housing 32. For firm connection with the connector 2, the interior of the lamp cap 3 may include a second connection portion 35, where the second connection portion 35 is in a fixed connection with the housing 32, and the two may be integrally provided or may be assembled later.
