Description

Technical Field

[0001] The invention relates to the field of LED lamps, and in particular to a quick-detachable LED lamp belt capable of dissipating heat and an LED lamp cover thereof. Background Art

[0002] LED, light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. Generally, when the ambient temperature of LED is around 20 degrees, the normal working temperature is around 40 degrees. The life span is reduced by half for every 5 degrees increase in temperature, and the light decay speed is faster. It is best not to exceed 70 degrees. For this reason, a heat dissipation structure is needed to dissipate the heat of LED.

[0003] In the prior art, CN113236989B discloses a flexible SMD light strip that can improve the heat dissipation effect, including a flexible SMD light strip main body, an LED patch and a flexible PCB board are fixedly connected on the front side of the flexible SMD light strip main body, an attachment tape is arranged on the back side of the flexible SMD light strip main body, an anti-bending lampshade is fixedly connected on the front side of the flexible SMD light strip main body, and a heat dissipation mechanism is fixedly connected on the outer surface of the flexible SMD light strip main body.

[0004] The heat dissipation mechanism comprises a heat conductive sheet, the outer surface of which is fixedly connected to the outer surface of the flexible patch light strip body, and one side of the heat conductive sheet is fixedly connected to a heat collecting bin.

[0005] A soft anti-bending plate is fixedly connected to the inner wall of the anti-bending lampshade, and a non-glue base material arc plate is arranged inside the soft anti-bending plate.

[0006] Although the flexible structure can ensure the multi-directional adjustment of the LED and the heat dissipation of the LED lamp at the same time, the LED lamp fixing structure adopts an adhesive method to fix the LED lamp, and it is inconvenient to disassemble the LED lamp after fixation. Secondly, it is inconvenient to adjust the LED lamp after fixation. Secondly, the heat dissipation structure of the equipment uses heat to drive the gas to expand, and then dissipates heat through expansion and extrusion connection. However, if the temperature of the LED lamp reaches the case where the gas expansion is large, the temperature of the LED lamp itself is already too high. At this time, if heat is dissipated, the LED itself has been damaged, so it cannot increase the service life of the LED lamp. Summary of the invention

DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The following describes an embodiment of the present invention based on its overall structure.

[0044] A quick-detachable LED light strip capable of dissipating heat, such as Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, it includes a flexible circuit board 4, a plurality of groups of LED lamp beads 401 are installed on the top of the flexible circuit board 4, a connector 402 is connected to one end of the flexible circuit board 4, and a thermal conductive strip 5 is installed on the outside of each group of LED lamp beads 401 of the flexible circuit board 4. The thermal conductive strip 5 is a Z-folding type, and the top of the thermal conductive strip 5 is bonded to the outside of the LED lamp bead 401. The thermal conductive strip 5 is a thermal conductive plate 501, and the outside of the thermal conductive plate 501 is bonded to the outer wall of the LED lamp bead 401. Both ends of the thermal conductive plate 501 are provided with inclined grooves 502, which can facilitate the adjustment of the flexible circuit board 4.

[0045] See also Figures 1 to 7 , an LED lampshade, the LED lampshade comprises a base plate 1, a lampshade 2 and the LED light strip of claim 1, both sides of the top of the base plate 1 are provided with snap-fit ​​grooves 101, the inner wall of the base plate 1 is provided with a heat-conducting cavity 102, the heat-conducting cavity 102 is aligned with the bottom end of the flexible circuit board 4, the base plate 1 is located on both sides of the heat-conducting cavity 102 and has multiple groups of heat dissipation holes 103, each group of heat dissipation holes 103 is aligned with the heat-conducting strip 5, the outer wall of the base plate 1 is located on the outside of the heat-conducting cavity 102 and has heat dissipation grooves 104, the heat dissipation grooves 104 are connected with the heat dissipation holes 103, both ends of the base plate 1 and the lampshade 2 are installed with heads 3, the heat-conducting strip 5 is fitted with the inner wall of the base plate 1, and the heat-conducting strip 5 seals the heat dissipation holes 103, the edge of the lampshade 2 is provided with a snap-fit ​​strip 201, the lampshade 2 The snap-fitting strip 201 is snap-fitted with the snap-fitting groove 101, and the outer end of the heat-conducting strip 5 is located between the snap-fitting strip 201 and the base plate 1. The snap-fitting strip 201 is used to limit the heat-conducting strip 5, so that the base plate 1 and the lampshade 2 can be conveniently assembled. During the assembly process, the flexible circuit board 4 is first placed in the base plate 1, and the heat-conducting strip 5 is fixed by the lampshade 2, thereby fixing the flexible circuit board 4. There is no need to fix the flexible circuit board 4 with glue, screws, etc., thereby improving the installation efficiency. When heat dissipation is performed, the heat dissipation hole 103 dissipates the heat into the heat dissipation groove 104. The heat dissipation groove 104 is at a certain distance from the wall, so that the dissipated heat can contact with the outside air through the heat dissipation groove 104, thereby improving the heat dissipation and thus improving the heat dissipation efficiency.

[0046] See also Figure 4 A plurality of fixing screw holes 105 are installed inside the heat conduction cavity 102 , and the bottom plate 1 is fixed to the external wall through the fixing screw holes 105 , so that the bottom plate 1 can be conveniently fixed.

[0047] See also Figure 3 The outer wall of the lampshade 2 is provided with heat dissipation strips 202, and a plurality of heat dissipation strips 202 are used to exchange the heat inside the lampshade 2 with the outside air, so as to facilitate the heat dissipation of the lampshade 2 in one step.

[0048] See also Figures 7 to 9, which is the second embodiment of the present application. The difference from the first embodiment is that the structure of the thermally conductive strip 5 is different, thereby performing different heat dissipation. The specific difference is that the thermally conductive strip 5 is a hollow strip 504, the hollow strip 504 is hollow inside, and a sealing plate 503 is installed on the outer wall of the hollow strip 504. The hollow strip 504 matches the heat dissipation hole 103. During the installation process, the hollow strip 504 can pass through the heat dissipation hole 103 and extend to the outside of the bottom plate 1, thereby improving the heat dissipation effect, and fits with the inner wall of the bottom plate 1 through the sealing plate 503, and seals the heat dissipation hole 103.

[0049] See also Figures 10 to 12 , which is the third embodiment of the present application. The difference from the first embodiment is that the structure of the thermally conductive bar 5 is different. The flexible circuit board 4 is limited while dissipating heat. The thermally conductive bar 5 is a support bar 505. The support bar 505 extends to the bottom of the flexible circuit board 4, and the flexible circuit board 4 is supported by the support bar 505 to improve the strength of the flexible circuit board 4.

Heat dissipation cover plates 506 are provided on both sides of the support bar 505, and the heat dissipation holes 103 are sealed by the heat dissipation cover plates 506.

[0050] During the use of the lamp, the base plate 1 needs to be installed on the wall (or the top of the wall) first, and the base plate 1 needs to be fixed by screws passing through the fixing screw holes 105, and then the flexible circuit board 4 is inserted into the base plate 1, and the heat-conducting strips 5 are inserted into the snap-fit ​​grooves 101. When the flexible circuit board 4 is fully inserted into the base plate 1, each group of heat-conducting strips 5 is aligned with the heat dissipation holes 103, and then the lampshade 2 is also installed in the base plate 1. At this time, the flexible circuit board 4 is pushed to fit the inside of the base plate 1, so that the heat-conducting strips 5 fit the inside of the base plate 1, and the lampshade 2 is fixed to the inside of the base plate 1 through the snap-fit ​​strips 201. At this time, the snap-fit The strip 201 is inserted into the snap-fit ​​groove 101 to fix the lampshade 2. The snap-fit ​​strip 201 also squeezes the heat-conducting strip 5 to fit tightly inside the bottom plate 1, thereby fixing and limiting the position of the flexible circuit board 4. There is no need to use glue or bolts or other structures for fixing, which can improve the fixing efficiency. After fixing, the two groups of end caps 3 are fixed to the outside of the bottom plate 1 and the lampshade 2 to limit the position of the bottom plate 1 and the lampshade 2, and the wires of the connector 402 are extended from one group of end caps 3 to the outside to complete the assembly of the lamp. After that, the flexible circuit board 4 is connected to the external power supply through the connector 402, so that the lamp can be used normally.

[0051] When the lamp is in use, the heat generated by each group of LED lamp beads 401 will be dissipated to the heat dissipation holes 103 of the bottom plate 1 through each group of thermal conductive strips 5, and the heat will be dissipated into the heat dissipation groove 104 through the heat dissipation holes 103. The heat dissipation groove 104 is at a certain distance from the wall, so that the dissipated heat can contact with the outside air through the heat dissipation groove 104, thereby improving the heat dissipation, thereby improving the heat dissipation efficiency, and through the heat conduction cavity 102, the flexible circuit board 4 can also be transferred to the outside of the thermal conductive strip 5, thereby further improving the heat dissipation effect.

[0052] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
