[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 8 As shown, the present invention provides a car grille light strip, including an extruded thin-walled plastic shell 1, the plastic shell 1 including a light-shielding portion 11 located in the middle and lower part and a light-transmitting portion 12 located at the top, the light-shielding portion 11 and the light-transmitting portion 12 are extruded simultaneously by co-extrusion, a light-transmitting seat 2 is provided in the plastic shell 1 and the two are clearance-matched, specifically, the light-transmitting seat 2 is directly inserted into the plastic shell 1, a mounting cavity 21 is provided at the bottom of the light-transmitting seat 2, a strip-shaped lamp holder 3 is pasted in the mounting cavity 21, a plurality of lamp beads 4 are provided on the surface of the lamp holder 3 along the length direction, an arc-shaped ball head is provided on the top of the light-transmitting seat 2, and a light diffusing agent is added to the light-transmitting seat 2 so that the whole presents an atomized light-transmitting effect.

[0028] In the above solution, the light-transmitting seat 2 is grooved and extended upward on the bottom surface to form the installation cavity 21 , or the light-transmitting seat 2 is grooved and extended inward on the lower side surface to form the installation cavity 21 .

[0029] Specifically, the thickness of the light-transmitting portion 12 on the top of the plastic housing 1 gradually decreases from the middle to both sides to form a convex lens structure to improve light-gathering power.

[0030] In addition, the top cross-section of the plastic housing 1 is an arc-shaped structure, and the light-transmitting portion 12 occupies the entire arc-shaped area or a portion of the arc-shaped area.

[0031] In addition, the cross section of the plastic housing 1 presents shape.

[0032] Specifically, the material of the light-shielding portion 11 contains black light-shielding particles in addition to the material of the light-transmitting portion 12 .

[0033] Specifically, the light-transmitting portion 12 of the plastic housing 1 is made of transparent PA, PU, ​​or PE, and the light-shielding portion 11 of the plastic housing 1 is made of transparent PA, PU, ​​or PE with black light-shielding particles added thereto. The addition of UV-resistant materials to the plastic housing 1 provides UV protection for the entire plastic housing 1, slowing down yellowing and aging.

[0034] Specifically, the material of the light-transmitting seat 2 is PP or PC.

[0035] Specifically, the lamp beads 4 are LED lamp beads or RGB color lamp beads.

[0036] Furthermore, the light-transmitting seat 2 is inserted into the plastic housing 1 with a clearance fit between the two.

[0037] Furthermore, positioning blocks 13 are integrally formed on the bottom of the plastic housing 1 and are spaced apart along the length of the plastic housing 1. When the plastic housing 1 is inserted into the annular groove of the car grille, the positioning blocks 13 are directly locked in place to prevent it from falling out. Of course, the positioning blocks 13 can also be attached to the annular groove of the car grille by adhesive.

[0038] The present invention can install lamp beads 4 on the lamp holder 3 at intervals, and adjacent lamp beads 4 can maintain a large distance between them. The light source generated by the lamp beads 4 will become uniform and soft after being atomized by the light-transmitting holder 2, and then be irradiated out through the light-transmitting portion 12. The light-transmitting portion 12 is set to a convex lens structure to improve the focusing effect, so that the light finally emitted by the lamp strip is soft, uniform and bright, with good consistency, and has a better decorative effect.

[0039] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the invention. Any simple modification, equivalent change or modification made to the above embodiment based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
