[0002] LED car lights refer to the use of LED technology for both interior and exterior lighting. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloading load tests. LED car lights can be widely used to create an in-car environment with a service life of 50,000 hours. The structure of LED is sturdy and not easily affected by vibration, and the brightness of light output will not drop significantly during use. LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and indicator lights, etc.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] The dual-color light-guiding lens structure comprises a lens body 1 for light transmission of the LED light module and a shielding strip 3 for shielding stray light scattered from the LED on the LED module to the light-emitting side of the light-guiding lens;

[0020] The lens body 1 is arranged in an arc shape, a plurality of light guides 2 are arranged on the concave side of the lens body 1, and a particle surface 5 for displaying light is arranged on the convex side of the lens body 1. The light guides 2 are arranged in an equidistant array on one side of the concave surface of the lens body 1, and the end of the light guide surface of the light guide 2 is arranged in a hemispherical shape. The particle surface 5 is composed of fine particles, and the fine particles on the particle surface 5 are arranged in a rhombus shape.

[0021] The lens body 1 is made of acrylic light-transmitting material with good light transmittance. The special hemispherical light-guiding surface of the light guide 2 aggregates the light emitted by the LED on the original LED light-emitting module, and changes the angle of the light by 90 degrees. After the light path is changed, it fills the entire light-guiding lens, and then through the countless tiny granular diamonds on the side particle surface 5 of the light-guiding lens, the original individual light is transformed into an overall surface light that is as uniform and dazzling as a galaxy.

[0022] See also Figure 2-3 :

[0023] The shielding strip 3 is set on one side of the lens body 1 by welding. The shielding strip 3 is set to black. A stepped arc-shaped fitting surface 4 is set on the lens body 1. The shielding strip 3 is set on the fitting surface 4 by welding. The lens body 1 and the shielding strip 3 are both made of acrylic material.

[0024] By welding a carefully designed black shielding strip 3 on the lens body 1, the black shielding strip 3 uses a two-color welding technology to firmly bond the transparent light-guiding lens body 1 and the black shielding strip 3 together. The main function of the black shielding strip 3 is to block the stray light scattered by the LED on the LED module to the light-emitting side of the light-guiding lens, thereby ensuring the complete light distribution of this design.

[0025] The dual-color light-guiding lens structure combines the original light-guiding lens and the black shielding strip 3 into one. In addition to reducing the number of lamp components, the independent and unified light lens structure design also enhances the overall appearance of the car. The ingenious structural design greatly reduces the space for the headlights, reduces the production process in the lamps, saves costs, and enhances product competitiveness.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
