Description

Technical Field

[0001] The utility model relates to the technical field of light strips, in particular to a surface luminous COB atmosphere light strip for automobiles. Background Art

[0002] Currently, automotive ambient lighting is installed on the car's roof and sheet metal. For example, the Chinese utility model patent application number 202222640648.8 discloses an "Automotive Ambient Light and Automobile," which includes an ambient light base, an ambient light frame, an ambient light LED, and an ambient light PCBA. The ambient light base is connected to the ambient light frame, and the ambient light LED and ambient light PCBA are mounted on the ambient light frame. Existing ambient light LEDs emit light with no directionality, resulting in insufficient light concentration. If the workmanship of the ambient light base and the ambient light frame is poor, resulting in light leakage, the ambient light illumination effect will be poor after the ambient light is installed in the car. Utility Model Content

[0003] In order to overcome the defects of the prior art, the present invention provides a surface luminous COB ambient light strip for automobiles to solve the above-mentioned problems.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a surface-emitting COB atmosphere light strip for automobiles, comprising a mask, a COB light source board, a light guide strip and bright silver dragon adhesive tape, the COB light source board is arranged in the light guide strip, an installation cavity is formed in the mask, the light guide strip is arranged in the installation cavity, and the bright silver dragon adhesive tape wraps a part of the light guide strip so that the light guide strip forms a light-emitting surface at a position facing the top surface of the mask.

[0005] It is worth noting that the light guide bar is provided with a light source board mounting groove, and the COB light source board is arranged in the light source board mounting groove; a support plate is provided on the lower side of the light source board mounting groove to support the COB light source board.

[0006] Preferably, a gap is formed between the support plate and the wall of the light source board mounting groove to lead the wires of the COB light source board out of the light guide bar.

[0007] Optionally, the mask also includes side walls and bottom side clips, the top surface is connected to the bottom side clips through the side walls, and after the light guide bar is set in the mounting cavity, the lower side of the light guide bar is connected to the upper surface of the bottom side clips to support the light guide bar.

[0008] Specifically, covers are provided on both sides of the mask.

[0009] Preferably, an adhesive member is provided on the lower side of the light guide strip.

[0010] The beneficial effect of the present invention is that: in the surface-emitting COB atmosphere light strip for automobiles, the opacity of the bright silver dragon tape is utilized to cover a portion of the light guide strip, leaving only the position of the light guide strip facing the top surface of the mask uncovered, thereby forming a light-emitting surface; when the COB light source board is working and emitting light, the light can only be emitted through the light-emitting surface, thereby playing a guiding role; after the light is emitted from the light-emitting surface, it can be irradiated outward through the mask, so that the light is concentrated, thereby ensuring the effect of the atmosphere light illumination.

DETAILED DESCRIPTION

[0017] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0018] like Figures 1-5 As shown, a surface-emitting COB atmosphere light strip for automobiles includes a mask 1, a COB light source board 2, a light guide bar 3 and a bright silver dragon adhesive tape 4. The COB light source board 2 is arranged in the light guide bar 3. An installation cavity is formed in the mask 1. The light guide bar 3 is arranged in the installation cavity. Figure 1 and 2 As shown, the bright silver dragon tape 4 wraps a portion of the light guide strip 3 so that the light guide strip 3 forms a light emitting surface 31 at a position facing the top surface 11 of the mask 1 .

[0019] In the surface-emitting COB atmosphere light strip for automobiles, the opacity of the bright silver dragon tape 4 is used to cover a portion of the light guide strip 3, leaving only the position of the light guide strip 3 facing the top surface 11 of the mask 1 uncovered, thereby forming a light-emitting surface 31; when the COB light source board 2 is working and emitting light, the light can only be emitted through the light-emitting surface 31, thereby playing a guiding role; after the light is emitted from the light-emitting surface 31, it can be irradiated outward through the mask 1, so that the light is concentrated, ensuring the effect of the atmosphere light illumination.

[0020] In this embodiment, the COB light source board 2 is a metal-based printed circuit board encapsulating a plurality of LED chips.

[0021] Preferably, Figures 2-4 As shown, the light guide strip 3 is provided with a light source board mounting slot 32, and the COB light source board 2 is disposed within the slot. A support plate 33 is provided below the slot to support the COB light source board 2. Once the COB light source board 2 is inserted into the slot, the support plate 33 prevents it from falling out, thereby ensuring stable operation of the ambient light strip.

[0022] It is worth noting that if Figure 3 As shown, a gap 34 is formed between the support plate 33 and the wall of the light source board mounting slot 32 to lead the wires of the COB light source board 2 out of the light guide bar 3. The wires of the COB light source board 2 are led out of the gap 34 and pass through the bright silver dragon adhesive tape 4 to be electrically connected to the controller located outside the ambient light strip.

[0023] Specifically, if Figure 2 and 5 As shown, the face mask 1 also includes side walls 12 and bottom side clips 13, and the top surface 11 is connected to the bottom side clips 13 through the side walls 12. After the light guide bar 3 is set in the installation cavity, the lower side of the light guide bar 3 is connected to the upper surface of the bottom side clips 13 to support the light guide bar 3. In this embodiment, side walls 12 are provided on both sides of the top surface 11, the upper side surfaces of the side walls 12 are connected to the top surface 11, and the lower side surfaces of the side walls 12 are connected to the bottom side clips 13. Therefore, the face mask 1 includes two bottom side clips 13, and the light guide bar 3 can be supported by the cooperation of the two bottom side clips 13. In this embodiment, the top surface 11 can be set to be transparent, and the side walls 12 and the bottom side clips 13 can be set to be black, so that after the light passes through the light exit surface 31, it can only pass through the transparent top surface 11.

[0024] Optional, such as Figure 1As shown, both sides of the mask 1 are provided with covers 5. After the cover 5 is provided, dust can be prevented from entering the installation cavity, thus having a dust-proof effect.

[0025] It is worth noting that if Figure 1 and 2 As shown, an adhesive member 6 is provided on the lower side of the light guide bar 3. Specifically, the adhesive member 6 is connected to the bright silver dragon adhesive tape 4 located on the lower side of the light guide bar 3. Through the adhesive member 6, the entire automotive surface emitting COB ambient light strip can be adhered to the roof or sheet metal of the car.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
