Description

Technical Field

[0002] LED lights refer to lamps that use light-emitting diodes as light sources. Generally, silver glue or white glue is used to solidify the semiconductor LED onto the bracket, and then silver wire or gold wire is used to connect the chip and circuit board. The surrounding area is sealed with epoxy resin to protect the internal core wire. Finally, the outer shell is installed. LED lights have the advantages of energy saving, long life, environmental protection, and shock resistance. They can directly emit seven colors of light and are usually used in traffic lights, display screens, car signal lights and other fields.

[0003] Among them, LED light strips are mostly used as lighting decorations on the facades of buildings. The LED light strips are usually stuck inside the mounting base. Since the LED light strips are prone to heat up during long-term use, and the mounting base will cause the heat dissipation effect of the LED light strips to be reduced, it is easy to cause the LED light strips to be damaged, and the light strips are less safe to use.

[0004] Therefore, it is necessary to invent a heat dissipation structure for LED lamps to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides Figures 1 to 4The heat dissipation structure of an LED lamp shown in the figure includes a mounting bracket 1, and mounting plates 11 are fixedly connected to the left and right surfaces of the mounting bracket 1. A connecting hole 12 is provided on the surface of the mounting plate 11, and an expansion screw 13 is inserted into the inside of the connecting hole 12. Two groups of protective shells 2 are provided on the surface of the mounting bracket 1, the right protective shell 2 is fixedly connected to the surface of the mounting bracket 1, and the left protective shell 2 is slidably connected to the surface of the mounting bracket 1, and a lamp strip body 3 is provided between the two groups of protective shells 2. A heat conducting plate 21 is fixedly connected to the inside of the protective shell 2, and a plurality of groups of heat dissipating fins 22 are fixedly connected to the outer surface of the heat conducting plate 21, and the inner surface of the heat conducting plate 21 abuts against the side of the lamp strip body 3, and the heat dissipating fins 22 are inclined. The surface of the mounting bracket 1 is provided with a plurality of groups of heat dissipating grooves 14, and the front end of the protective shell 2 is fixedly connected to a plurality of groups of transparent cards 24, which are stuck on the front surface of the lamp strip body 3.

[0032] Among them, in the process of installing the mounting bracket 1, first drill a hole on the building surface, fill the hole with the embedded expansion screw 13, then pass the expansion screw 13 through the connecting hole 12 to connect with the embedded part, fix the mounting bracket 1 on the building surface, then clamp the light strip body 3 between the two sets of protective shells 2, and install and fix the light strip body 3. At the same time, in the early stage of construction, the mounting bracket 1 can be embedded in the building surface, and the light strip body 3 can be directly installed during the subsequent construction process, which can effectively improve the installation efficiency.

[0033] Specifically, during the use of the light strip body 3, the heat generated by the light strip body 3 is conducted to the surface of the heat dissipation fins 22 through the heat conducting plates 21 on both sides, and the heat is dissipated under the action of the external natural wind, thereby effectively reducing the heat generated by the light strip body 3. At the same time, the heat dissipation groove 14 makes the bottom of the light strip body 3 in an overhead state, and the natural wind passes through the inside of the heat dissipation groove 14, taking away part of the heat of the light strip body 3 to assist in the heat dissipation of the light strip body 3, thereby further improving the heat dissipation effect of the light strip body 3.

[0034] In addition, since the mounting bracket 1, the protective shell 2 and the light strip body 3 are installed outdoors, dust will accumulate on the surface of the heat dissipating fins 22 during long-term use. Excessive dust accumulation will affect the heat dissipation effect of the heat dissipating fins 22. The heat dissipating fins 22 are set to an inclined shape. On rainy days, rainwater can directly wash the surface of the heat dissipating fins 22, clean the surface of the heat dissipating fins 22, and effectively improve the heat dissipation effect of the heat dissipating fins 22.

[0035] See Figures 2 to 5The front surface of the mounting bracket 1 is provided with three groups of positioning grooves 15, and the rear end of the left protective shell 2 is fixedly connected with three groups of positioning blocks 23. The positioning blocks 23 are slidably connected to the positioning grooves 15. The left end position of the front surface of the mounting bracket 1 is fixedly connected with two groups of positioning plates 16. The surface of the positioning plate 16 is provided with a threaded hole 17. The side of the left protective shell 2 is fixedly connected with a support block 25, and the surface of the support block 25 is fixedly connected with a connecting block 26. The internal rotation of the connecting block 26 is connected with a clamping block 28. The side of the clamping block 28 is fixedly connected with a fixing screw 27. The fixing screw 27 is threadedly connected to the threaded hole 17, and the outer end of the fixing screw 27 is fixedly connected with an adjusting knob 29.

[0036] At the same time, during the installation of the light strip body 3, first rotate the fixing screw 27 counterclockwise and rotate the fixing screw 27 outward. At this time, the clamping block 28 rotates inside the connecting block 26, and pulls the protective shell 2 on the left to the left to increase the distance between the two groups of protective shells 2. Then, the light strip body 3 is clamped between the two groups of protective shells 2. Next, rotate the fixing screw 27 clockwise, and push the protective shell 2 on the left to the right during the process. Cooperate with the protective shell 2 on the right to clamp and fix the light strip body 3, and clamp the light strip body 3 on the back side of the transparent card 24, and use the transparent card 24 to further fix the light strip body 3.

[0037] The working principle of the present invention is as follows: part of the heat generated by the light strip body 3 is dissipated outwards through the heat dissipation groove 14, and part of the heat is conducted to the surface of the heat dissipation fins 22 through the heat conducting sheet 21. The heat is dissipated under the action of the natural wind from the outside, thereby reducing the heat generated by the light strip body 3 and effectively improving the safety of the use of the light strip body 3. Moreover, since the distance between the two sets of protective shells 2 is adjustable, light strip bodies 3 of different widths can be fixed, thereby improving adaptability.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
