Description

Technical Field

[0001] The utility model relates to the technical field of light belts, in particular to a reflection structure and a flexible light belt. Background Art

[0002] LED light belts are generally divided into two types: flexible LED light belts and LED rigid light bars. However, they generally also include old-fashioned light belts that connect LEDs with wires, such as flat three-wire 4.3W / m, flat four-wire 6.48W / m, flat five-wire 8.64W / m light belts, etc.; COB packaging, the full name of which is Chip on Board (COB), is a technology to solve the LED heat dissipation problem. It is to adhere bare chips to an interconnection substrate with conductive or non-conductive glue, and then perform wire bonding to achieve its electrical connection. Some chips are directly exposed to the air, which is vulnerable to pollution or human damage, affecting or destroying the chip function. Therefore, the chips and bonding leads are encapsulated with glue. People also call this packaging form soft encapsulation.

[0003] Existing flexible COBs usually use transparent silica gel or phosphor-containing glue. The light color of the lamp beads can emit light 360 degrees. For example, Chinese Patent Publication No. CN114877270A discloses "a flexible light belt", which has a covering on the surface of the flexible circuit board and the lamp beads. The covering is transparent silica gel or phosphor-containing glue. The light color of the lamp beads can emit light 360 degrees. After using a conventional pick-and-place machine for chip placement, a layer of transparent silica gel can be covered on the FPC board. Moreover, the color of the lamp beads can be controlled to ensure high color consistency of the light belt. If the color needs to be changed, it is also possible to choose to coat a covering with phosphor and use a conventional circuit board for production.

[0004] However, during the installation of the light belt, it is usually fixed to a bracket or a wall. Due to the flexible light belt covering materials such as transparent silica gel, the light color of the lamp beads is scattered and emits light 360 degrees, resulting in low light efficiency and brightness on the side where actual lighting is required, reducing the practical experience. It is necessary to select a higher-power light belt for lighting to meet the requirements, increasing the electricity cost during use. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art that the light color of the lamp beads is scattered and emits light 360 degrees, resulting in low light efficiency and brightness on the side where actual lighting is required and being difficult to meet the requirements, etc., and to propose a reflection structure and a flexible light belt.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A reflective structure is designed and set on a flexible light strip. It is characterized in that it includes a reflective plate. The reflective plate is set at the bottom of the transparent adhesive layer of the flexible light strip. Connecting plates are arranged on both sides of the reflective plate. Connection grooves are formed on the transparent adhesive layer and are matched with the reflective plate and the two connecting plates. Mirrors for reflecting light are arranged on the inner walls of the reflective plate and the connecting plates.

[0008] Furthermore, elastic structures are arranged at the joints of the connecting plates and the reflective plate. The reflective plate cooperates with the two elastic structures so that the two connecting plates clamp the connection groove.

[0009] Furthermore, a positioning structure is arranged on the reflective plate. Limiting grooves corresponding to the lamp beads are formed on the connection groove. The positioning structure and the limiting grooves cooperate with each other to limit the reflective plate.

[0010] Furthermore, the positioning structure includes a through groove formed on the reflective plate. An elastic sheet is fixedly connected in the through groove. A limiting protrusion matched with the limiting groove is fixedly arranged on the elastic sheet.

[0011] Furthermore, two snap grooves are arranged on the connection groove. Snap portions matched with the snap grooves are fixedly arranged on the inner walls of the connecting plates.

[0012] Furthermore, a plurality of reinforcing portions are formed on the outer wall of the connecting plate to increase the anti-bending property of the connecting plate.

[0013] The present utility model also proposes a flexible light strip, which includes the above-mentioned reflective structure, and also includes a circuit structure and lamp beads. It is characterized in that a plurality of the lamp beads are arranged at intervals on the circuit structure, and the outside of the circuit structure is wrapped with a transparent adhesive layer.

[0014] A reflective structure and a flexible light strip proposed by the present utility model have the following beneficial effects:

[0015] In the present utility model, by setting the reflective structure, the light at the rear side and both sides of the light strip is concentrated and reflected along the side that needs to be irradiated, so that while ensuring that the lamp core is not contaminated and damaged, the light efficiency of the light strip will not be reduced, thereby avoiding purchasing a light strip with a higher power and saving the electricity cost.

[0016] Secondly, in the present utility model, by setting the connection groove to connect the reflective plate and the connecting plate, and by setting the limiting groove to cooperate with the positioning structure, each reflective plate is matched with the lamp core, thereby avoiding the cost and weight increase caused by installing the reflective plate as a whole, and at the same time not affecting the flexibility of the light strip.

[0024] In the present utility model, by providing the reflector 4 and the connecting plates 5, the light at the rear side and both sides of the light strip is concentrated and reflected along the side that needs to be irradiated, so that while ensuring that the lamp core is not contaminated and damaged, the light efficiency of the light strip will not be reduced, thereby avoiding purchasing a light strip with a higher power and saving the electricity cost.

[0025] Further, in this embodiment, elastic structures 7 are arranged at the joints of the connecting plates 5 and the reflector 4, and the reflector 4 cooperates with the two elastic structures 7 to clamp the connecting groove 6 with the two connecting plates 5. In some embodiments, columnar protrusions matching the elastic structures 7 are provided at the bottom of the transparent adhesive layer 3.

[0026] Furthermore, in this embodiment, a positioning structure 8 is arranged on the reflector 4, a limiting groove corresponding to the lamp beads 2 is opened on the connecting groove 6, and the positioning structure 8 and the limiting groove cooperate with each other to limit the reflector 4. Through the cooperation of the limiting groove and the positioning structure 8, each reflector 4 is matched with the lamp beads 2 one by one, thereby avoiding the cost and weight increase caused by installing the reflector 4 as a whole, and at the same time not affecting the flexibility of the light strip.

[0027] It should be noted that in this embodiment, the positioning structure 8 includes a through groove formed in the reflector 4. An elastic sheet 81 is fixedly connected in the through groove, and a limiting protrusion matched with the limiting groove is fixedly arranged on the elastic sheet 81.

[0028] In addition, in this embodiment, two snap grooves are provided on the connecting groove 6, and snap portions 51 matched with the snap grooves are fixedly arranged on the inner walls of the connecting plate 5. The cooperation of the snap portions 51 and the connecting groove 6 prevents the installed reflector 4 and the connecting plate 5 from falling off.

[0029] More specifically, in some embodiments, a plurality of strengthening portions are formed on the outer wall of the connecting plate 5 to increase the anti-bending property of the connecting plate 5.

[0030] The present utility model also provides a flexible light strip, which includes the above-mentioned reflection structure, and further includes a circuit structure 1 and lamp beads 2. A plurality of lamp beads 2 are arranged at intervals on the circuit structure 1, and the outside of the circuit structure 1 is wrapped with a transparent glue layer 3.

[0031] Working mode: During operation, by arranging the reflector 4 and the connecting plate 5, the light at the rear side and both sides of the light strip is concentrated and reflected along the side where illumination is required. Thus, while ensuring that the lamp core is not contaminated and damaged, the light efficiency of the light strip is not reduced. The cooperation of the snap portions 51 and the connecting groove 6 prevents the installed reflector 4 and the connecting plate 5 from falling off. The positions of the reflector 4 and the connecting plate 5 are restricted by the cooperation of the limiting protrusion on the elastic sheet 81 and the limiting groove, avoiding the cost and weight increase caused by the overall installation of the reflector 4, and at the same time not affecting the flexibility of the light strip.
