具体实施方式detailed description
参阅图1至图6所示，本发明的一种I形LED灯，包括长条形的散热底板1，其采用铝合金材质制成，在散热底板1背面沿长度方向间隔设有若干用于增加散热面积的散热肋条。在散热底板1正面设有铝基板2，所述铝基板2通过导热胶水贴设在散热底板1上，这样具有结构简洁、导热效果好且组装方便的优点，当然其也可以采用常规的螺丝连接安装的方式，这均属于本领域的常规技术。在铝基板2上分布有若干LED灯芯3，在铝基板2沿长度方向的端部设有USB型低压接口4，USB型低压接口4输出端与各LED灯芯3连接，USB型低压接口4输入端通过USB型低压接头与外部驱动电源连接。参阅图9所示，所述USB型低压接口4内间隔设有两片平行的动导电触片4a，两片动导电触片4a之间为绝缘区；动导电触片4a通过引脚与各LED灯芯3连接；所述USB型低压接头内设有两片与动导电触片4a一一对应的静导电触片，静导电触片之间为绝缘区。采用这种结构，取消原USB型低压接口和USB接头中位于导电触片之间的数据触片，可以使导电触片之间的间隔增大，从而提高通过电压的强度。Referring to FIG. 1 to FIG. 6 , an I-shaped LED lamp of the present invention comprises an elongated heat-dissipating bottom plate 1 made of an aluminum alloy material, and a plurality of holes are arranged at intervals along the length of the rear surface of the heat-dissipating base plate 1 for A heat dissipation rib that increases the heat dissipation area. An aluminum substrate 2 is disposed on the front surface of the heat dissipation substrate 1 , and the aluminum substrate 2 is attached to the heat dissipation substrate 1 through the heat conductive glue, so that the structure has the advantages of simple structure, good heat conduction effect and convenient assembly, and of course, the conventional screw connection can also be adopted. The manner of installation is a matter of routine skill in the art. A plurality of LED wicks 3 are arranged on the aluminum substrate 2, and a USB type low voltage interface 4 is arranged at the end of the aluminum substrate 2 in the longitudinal direction. The output end of the USB type low voltage interface 4 is connected to each LED wick 3, and the USB type low voltage interface 4 is input. The terminal is connected to an external drive power source through a USB type low voltage connector. Referring to FIG. 9, the USB-type low-voltage interface 4 is provided with two parallel movable conductive contacts 4a, and two movable conductive contacts 4a are insulated regions; the movable conductive contacts 4a are connected by pins and The LED wick 3 is connected; the USB type low voltage connector is provided with two static conductive contacts corresponding to the movable conductive contacts 4a, and the static conductive contacts are insulated regions. With this structure, the data contacts between the conductive contacts of the original USB type low voltage interface and the USB connector can be eliminated, and the interval between the conductive contacts can be increased, thereby increasing the strength of the pass voltage.
上述所述的相互配合插接的USB型低压接口和USB型低压接头，与目前市场上销售的USB接口和USB接头结构基本一样，唯一不同的是：USB型低压接口内仅有两片动导电触片相与动导电触片相连接的引脚；将常规四触片结构中，位于中间的两个用于传输数据的触片取消，同时取消与相应触片连接的引脚。USB型低压接头的改进与USB型低压接口相适应，同样是取消位于中间的两个用于传输数据的触片于及与对应触片连接的引脚。The above-mentioned USB-type low-voltage interface and USB-type low-voltage connector that are mutually mated and inserted are basically the same as the USB interface and USB connector structure currently on the market, and the only difference is that there are only two pieces of dynamic conduction in the USB-type low-voltage interface. The pin is connected to the movable conductive contact; in the conventional four-contact structure, the two contacts in the middle for transmitting data are canceled, and the pin connected to the corresponding contact is cancelled. The improvement of the USB type low voltage connector is compatible with the USB type low voltage interface, and the same is used to cancel the two contacts for transferring data in the middle and the pins connected to the corresponding contacts.
在本实施例中，USB型低压接口4仅设置在铝基板2沿长度方向的其中一端，当然，为方便将灯具沿长度方向进行串联，也可以在铝基板2沿长度方向的两端设置USB型低压接口4。In the present embodiment, the USB type low voltage interface 4 is disposed only at one end of the aluminum substrate 2 in the longitudinal direction. Of course, in order to facilitate the series connection of the lamps in the longitudinal direction, the USB substrate 2 may be provided with USB at both ends in the longitudinal direction. Type low pressure interface 4.
在铝基板2***的散热底板1上设有灯罩5；所述灯罩5厚度为0.8～1.5mm，宽度W1为 25～45mm，高度H为8～13mm。灯罩5沿宽度方向的截面由中部的光扩散平面5a及一体成型在光扩散平面5a两端的弧形支承面5b组成；所述光扩散平面5a的宽度W2为15～25mm，弧形支承面5b的圆弧半径为5～12mm；采用这种结构的灯罩，不仅可以使灯具的体积缩小，而且具有很好的强度，可以避免灯罩受挤压后凹陷变形；光扩散平面5a与弧形支承面5b圆滑过渡连接。在散热底板1沿长度方向的两端设有端盖6，在与USB型低压接口4相对的端盖6上设有插孔6a，端盖6、散热底板1和灯罩5配合形成密封腔体。A heat shield 5 is disposed on the heat dissipation substrate 1 on the periphery of the aluminum substrate 2; the lamp cover 5 has a thickness of 0.8 to 1.5 mm, and the width W1 is 25 to 45 mm, height H is 8 to 13 mm. The cross section of the lampshade 5 in the width direction is composed of a light diffusion plane 5a at the center and an arcuate support surface 5b integrally formed at both ends of the light diffusion plane 5a; the width W2 of the light diffusion plane 5a is 15 to 25 mm, and the arcuate support surface 5b The radius of the arc is 5 to 12 mm; the lampshade with this structure can not only reduce the volume of the lamp, but also has good strength, and can avoid the deformation of the lamp cover after being pressed; the light diffusion plane 5a and the curved bearing surface 5b smooth transition connection. An end cover 6 is disposed at both ends of the heat dissipation base plate 1 in the longitudinal direction, and an end hole 6 is formed on the end cover 6 opposite to the USB type low voltage interface 4, and the end cover 6, the heat dissipation base plate 1 and the lamp cover 5 cooperate to form a sealed cavity. .

The 5c and the curved support surface 5b are integrally formed as a unitary structure. The use of such an outer opening structure makes the installation of the lamp cover simple. During installation, the positioning bar at one end of the lamp cover is first buckled into the positioning groove on the corresponding side, and then the positioning bar at the other end is buckled into the corresponding positioning groove. This operation can avoid the problem of inconvenience in installation due to the deformation of the lampshade. If the inner opening is used, the lamp cover can only be installed by inserting, which is not only inconvenient to install, but may not be inserted due to deformation of the lamp cover or the like, or the problem of excessively squeezing the lamp cover due to excessive force.

In this embodiment, the end cover 6 is sleeved on the outer wall of the lamp cover 5 and the heat dissipation base plate 1; the positioning hole 1b is respectively disposed at the proximal end portions of the heat dissipation base plate 1, and the inner wall of the end cover 6 is provided with the positioning hole 1b.

Preferably, two end limiting protrusions 6c are disposed in each end cover 6, and the two limiting pieces 6c respectively correspond to the curved supporting surface 5b. After the end faces are inserted into the heat dissipation base plate 1, the end cover is firstly engaged with the positioning protrusions 6b through the positioning holes 1b, and then passes through the limit of the limiting protrusions 6c, that is, the door cannot be freely withdrawn, and the structure is simple. ,stable.
进一步地，在端盖6外端面上设有挂板7，在挂板7上设有连接孔7a。这种结构，使得灯具既可以通过连接孔7a固定安装，也可以通过连接孔7a挂装，成为便携光源。Further, a hanging plate 7 is provided on the outer end surface of the end cover 6, and a connecting hole 7a is provided on the hanging plate 7.
