LED light-emitting board without dark side

Abstract

The invention discloses an LED light-emitting board without a dark side. The LED light-emitting board without the dark side comprises a light-emitting board body and an LED light bar; a notch is formed in one side of the light-emitting board body and arranged on the shady face; a boss is arranged on the light-emitting face; the LED light bar is installed at the notch of the light-emitting board body; an L-type aluminum connection board is installed on the side face of the box and fixed to the side face of the boss through heat conduction double-faced adhesive tape; and the back face of the L-type aluminum connection board is fixed to the shady face of the light-emitting board body. According to the LED light-emitting board without the dark side, the whole light-emitting face can emit light, the overall product is more attractive, the use effect is good, and the defect that a power line is prone to being pulled and broken can be overcome.

Description

technical field [0001] The invention relates to the field of LED light-emitting panels, in particular to an LED light-emitting panel without dark edges. Background technique [0002] LED light-emitting board is a common lighting device, which is widely used in various fields such as advertising, decoration, equipment lighting, and living lighting, especially high-end shop decoration or product shelf lighting such as cosmetics, clothing, and jewelry. With the continuous development of the industry, many high-end users have higher and higher requirements for LED light-emitting panels. The existing LED light-emitting panels can no longer meet the requirements of many high-quality customers, and further improvement is urgently needed.

Problems solved by technology

With the continuous development of the industry, many high-end users have higher and higher requirements for LED light-emitting panels. The existing LED light-emitting panels can no longer meet the requirements of many high-quality customers, and further improvement is urgently needed.

[0003] The existing LED light-emitting panels mainly have two structures, the traditional method A: refer to figure 1 As shown, the LED light bar 3 is installed on one side of the acrylic light-emitting board body 1, and the LED light bar 3 is fixed with an aluminum alloy fixing frame 8 with a groove. The aluminum alloy fixing frame 8 is 5-10mm wide. Therefore, the entire The 5-10mm of the edge of the light-emitting board will be affected by the aluminum alloy fixed frame, which cannot be illuminated and forms a dark frame. When installing, it is necessary to increase the installation space by 5-10mm

[0004] Traditional way B: such as figure 2 As shown in -4, set a light groove on one side of the acrylic light-emitting board body 1, fix the LED light bar 3 in the light groove, and then install an L-shaped aluminum connecting plate 4 between the LED light bar and the edge of the acrylic light-emitting board body , due to the need to set the light groove, the edge of the acrylic light-emitting board body will have a thickness of several millimeters, plus the width of the light groove itself, so the distance between the light-emitting point of the LED light-emitting board and the edge of the LED light-emitting board is 5-10mm. distance, the 5-10mm cannot be illuminated, making the edge of the entire LED light-emitting panel dark

[0005] Therefore, the user has to consider the special treatment of the 5-10mm edge when installing and using, and the final product cannot meet the requirement that the entire product is a light-emitting surface.

[0006] In addition, the connection between the existing LED light-emitting board power cord and the LED light bar is only connected by tin welding without any protective measures. Due to the length and weight of the power cord, the user will accidentally pull it off during use or installation. The connection between the LED light bar and the power cord makes the light-emitting board power off and cannot be used normally
