Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a polarized COB light strip. Background Technology

[0002] COB LED strips are LED strips manufactured using COB (Chip on Board) technology. By integrating and packaging multiple LED chips onto the same substrate, they achieve high brightness, high uniformity, and high energy efficiency. Their light is soft, uniform, and spotless, making them widely used in home, commercial, and outdoor applications.

[0003] However, in actual installation and use, the light emitted by the internal light-emitting components of COB light strips is relatively large and diffuse, resulting in limited light projection effect. There is no means to control and focus the light direction of the light strip.

[0004] Now, a new type of polarized COB lamp is proposed to address the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a polarized COB light strip to solve the problem mentioned in the background art of inconvenience in controlling and focusing the light direction of the light strip.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polarized COB light strip, comprising a PCB flexible board, a housing is provided on the outer side of the PCB flexible board, and an opening is provided inside the bottom end of the housing. Several LED chips are installed on the front end of the PCB flexible board. An insert plate is provided at the front end inside the housing, and several lenses are fixed at the front end of the insert plate. Three sets of internal holes are respectively provided at the top and bottom of the front end of the housing, and connecting screws are provided inside the internal holes.

[0009] As a further technical solution of this utility model, a thermal pad is attached and fixed to the rear end of the PCB flexible board, and the rear end of the thermal pad is attached and fixed to the rear end inside the shell. Two sets of heat sinks are horizontally fixed to the top and bottom ends of the shell, and several heat sinks are horizontally fixed to the rear end of the shell.

[0010] As a further technical solution of this utility model, the heat sinks are distributed at equal intervals.

[0011] As a further technical solution of this utility model, the top and bottom ends of the housing are respectively provided with three sets of mounting feet, and the mounting feet are symmetrically arranged about the horizontal center line of the housing. The mounting feet are provided with reserved holes inside, and fixing screws are respectively provided on both sides of the bottom end of the mounting feet.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides an embodiment: a polarized COB light strip, including a PCB flexible board 3, a housing 2 is provided on the outer side of the PCB flexible board 3, and an opening 1 is provided inside the bottom end of the housing 2. Several LED chips 4 are installed on the front end of the PCB flexible board 3. An insert plate 12 is provided inside the front end of the housing 2, and several lenses 11 are fixed on the front end of the insert plate 12. Three sets of inner holes 5 are respectively opened at the top and bottom of the front end of the housing 2. Connecting screws 10 are provided inside the inner holes 5. Connecting holes 13 are respectively opened at the top and bottom of the front end of the insert plate 12.

[0025] The front end of the lens 11 penetrates the interior of the opening 1, and the rear end of the lens 11 penetrates the interior of the rear end of the insert plate 12. Several lenses 11 are distributed at equal intervals on the insert plate 12. The rear end of the connecting screw 10 penetrates the interior of the inner hole 5 and is threadedly connected to the connecting hole 13.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, several lenses 11 are fixed to the front end of the insert plate 12 installed inside the housing 2. The lenses 11 can be used to control the light emitted by the LED chip 4, so that the light can be projected forward at a specific angle and polarized for directional light emission.

[0027] A thermal pad 15 is attached to the rear end of the PCB flexible board 3, and the rear end of the thermal pad 15 is attached to the rear end inside the housing 2. Two sets of heat sinks 9 are horizontally fixed at the top and bottom of the housing 2, and several heat sinks 8 are horizontally fixed at the rear end of the housing 2. The heat sinks 8 are distributed at equal intervals.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the heat-conducting pad 15 set at the rear end of the PCB flexible board 3 can conduct some of the heat generated by the main body of the PCB flexible board 3 during operation to the outer shell 2. By using the aluminum shell 2 and several aluminum heat sinks 8 and 9 on the outside of the shell 2, the heat dissipation area is increased, and the heat can be dissipated in the air to reduce the working temperature of the light strip.

[0029] The top and bottom of the housing 2 are respectively provided with three sets of mounting feet 6, and the mounting feet 6 are symmetrically arranged about the horizontal center line of the housing 2. The mounting feet 6 have reserved holes 7 inside. The two sides of the bottom of the mounting feet 6 are respectively provided with fixing screws 16. The rear ends of the top and bottom of the housing 2 are respectively provided with several screw holes 17. The fixing screws 16 pass through the interior of the mounting feet 6 and are rotatably connected in the screw holes 17. The reserved holes 7 pass through the interior of the mounting feet 6.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, after the mounting feet 6 are installed and fixed at the top and bottom of the housing 2 using fixing screws 16, the light strip can be conveniently installed and used using the mounting feet 6. It is a detachable mounting component.

[0031] Several LED chips 4 are evenly spaced on the front end of the PCB flexible board 3, and the front end of the PCB flexible board 3 is encapsulated with an adhesive layer 14.

[0032] Working Principle: In use, this invention utilizes lenses 11 fixed to the front end of the insert plate 12 inside the housing 2. These lenses 11 control the light emitted by the LED chip 4, allowing the light to be projected forward at a specific angle, thus achieving polarization. Simultaneously, when the light strip is installed inside the housing 2, the heat-conducting pad 15 at the rear end of the PCB flexible board 3 transfers some of the heat generated during operation to the outer housing 2. The aluminum housing 2, along with several aluminum heat sinks 8 and 9 on its outer side, increases the heat dissipation area, aiding in heat dissipation and reducing the operating temperature of the light strip. During installation, the mounting feet 6 are secured to the top and bottom of the housing 2 using screws 16, allowing for convenient installation and use of the light strip.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
