Description

Technical Field

[0001] The utility model relates to the technical field of light belts, in particular to a reflective light belt 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 is Chip on Board, 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, vulnerable to contamination or human damage, affecting or destroying the chip function. So, the chips and bonding leads are encapsulated with glue. People also call this packaging form soft encapsulation.

[0003] Existing flexible COBs usually use transparent silicone 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 silicone or phosphor-containing glue. The light color of the lamp beads can emit light 360 degrees. After using a conventional chip mounter for chip placement, a layer of transparent silicone can be covered on the FPC board. And the color of the lamp beads can be controlled, ensuring high color consistency of the light belt. If the color needs to be changed, it is also possible to choose to apply 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 being covered with materials such as transparent silicone, the light color of the lamp beads is scattered and emits light 360 degrees, resulting in low light efficiency and brightness on the side for actual lighting. If a reflective frame such as an aluminum alloy frame is set on the light belt, it will not only reduce the flexibility of the flexible light belt but also greatly increase the weight of the flexible light belt, making it inconvenient for transportation and installation. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art that the light color of the lamp beads is scattered and emits light 360 degrees, setting a reflective frame on the flexible light belt will reduce the flexibility of the flexible light belt and greatly increase the weight of the flexible light belt, making it inconvenient for transportation and installation, etc., and to propose a reflective light belt and a flexible light belt.

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

[0007] Design a reflective strip, which includes a base layer disposed in the transparent adhesive layer of a flexible light strip. Extension parts are arranged on both sides of the base layer. Reflective coatings are provided on the inner walls of the base layer and the extension parts. A transparent wear-resistant layer is arranged on the other side of the reflective coating;

[0008] A bracket is arranged on the base layer. Two sides of the bracket are respectively connected to the two extension parts. The base layers are connected by a connecting piece;

[0009] The connecting piece includes an elastic part and joints on both sides. The two joints are respectively connected to the two base layers.

[0010] Further, the joint includes a flexible part connected to the elastic part. A connecting groove matching with the flexible part is formed on the base layer. The flexible part is fixedly connected to the connecting groove.

[0011] Further, limiting plates are fixedly arranged at one ends of the flexible parts far away from the elastic part. Limiting grooves corresponding to the limiting plates are formed on the connecting groove. The limiting plates are fixedly connected to the limiting grooves.

[0012] Further, the bracket is embedded in the base layer. The bracket includes a bottom plate and support plates on both sides. The two support plates are respectively embedded in the two extension parts.

[0013] Further, an obtuse angle is formed between the support plate and the bottom plate, preferably an obtuse angle of degrees.

[0014] Further, positioning holes are formed on the base layers. A plurality of grooves for increasing friction are arranged on the outer wall of the base layer.

[0017] In the present utility model, by arranging the reflective coating, the base layer has a reflective effect. The light emitted by the flexible light strip in all directions is reflected to the side where lighting is required, avoiding the reduction of brightness caused by light dispersion, thereby improving the utilization rate of light;

[0018] Secondly, in the present utility model, reflecting light by arranging the reflective strip will not affect the flexibility of the flexible light strip compared with arranging a reflective frame, and at the same time avoid increasing the weight of the flexible light strip, which is more convenient for installing the flexible light strip.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

Extension parts 2 are provided on both sides of the base layer 1. Reflective coatings 3 are provided on the inner walls of the base layer 1 and the extension parts 2. On the other side of the reflective coating 3, a transparent wear-resistant layer is provided, and the wear-resistant layer is a transparent organic silicone resin layer;

[0026] A bracket 4 is provided on the base layer 1. The two sides of the bracket 4 are respectively connected to the two extension parts 2. The base layers 1 are connected by a connecting piece 5;

[0027] The connecting piece 5 includes an elastic part 51 and joints 52 on both sides. The two joints 52 are respectively connected to the two base layers 1.

[0028] In the present utility model, multiple base layers 1 are connected to each other through the elastic part 51 to form a reflective tape. By providing the elastic part 51, the reflective tape has elasticity and will not break due to the bending of the flexible light strip. Moreover, the position of the base layer 1 corresponds to the lamp beads of the flexible light strip. By providing the reflective coating 3, the base layer 1 has a reflective effect, and the light emitted 360 degrees by the flexible light strip is reflected to the side that needs illumination, avoiding the dispersion of light and resulting in low brightness, thereby improving the utilization rate of light.

[0029] Further, in this embodiment, the joint 52 includes a flexible portion 521 connected to the elastic portion 51. A connection groove matching with the flexible portion 521 is formed on the base layer 1. The flexible portion 521 and the connection groove are adhesively connected by glue to form a fixed connection. By providing the flexible portion 521, the connection is made smoother, and at the same time, the flexibility of the flexible light strip is prevented from being reduced due to the connection of the base layer 1.

[0032] In addition, in this embodiment, an obtuse angle, preferably 135 degrees, is formed between the support plate 42 and the bottom plate 41. The light reflected by the extension portion 2 is reflected obliquely upward, which not only increases the light efficiency utilization rate of the light strip, reflects the light effects on both sides to the side that needs illumination, but also the reflected light effect is emitted obliquely, which can increase the illumination range of the flexible light strip.

[0033] More specifically, in this embodiment, positioning holes 11 are formed on the base layer 1. A plurality of grooves for increasing friction are provided on the outer wall of the base layer 1. The positioning holes 11 are provided so that the base layer 1 corresponds to the lamp beads of the flexible light strip, thereby reflecting the light emitted by each lamp bead and improving the utilization rate of the light effect.
