AI Technical Summary
Existing driving lights have low efficiency, and their brightness and color temperature are insufficient to meet the lighting needs under complex road conditions. In particular, they have insufficient light penetration in rain, fog, at night, or in low visibility environments. Furthermore, high-power LED beads suffer from poor heat dissipation during long-term operation, leading to accelerated light decay, color temperature drift, and shortened lifespan.
An irregular prismatic lens is used in conjunction with a reflector array to form a dual-zone composite optical architecture, which achieves a more uniform light distribution and heat dissipation. The stepped structure of the position lamp lens forms a gradual brightness transition, increases the heat dissipation area and provides thermal isolation, and avoids material aging and light decay caused by heat concentration.
It improves luminous efficacy, enhances light uniformity and penetration, extends service life, reduces glare, and improves the visibility of road surface details. The system luminous efficacy reaches over 90 lm/W, the effective lighting luminous flux is increased by 35%, and the service life is extended by over 30%.

Description
Technical Field
[0001] This utility model relates to the field of driving light technology, specifically a driving light with a dual-zone composite optical architecture. Background Technology
[0002] Driving lights (such as headlights, daytime running lights, and fog lights) are critical components for safe vehicle operation, and their performance directly affects driving safety at night, in rainy or foggy weather, or in low-visibility conditions. In existing vehicle lighting systems, driving lights (such as daytime running lights, low beam headlights, or fog lights) generally suffer from insufficient luminous intensity, poor lighting effects, and inadequate heat dissipation, seriously impacting driving safety and user experience.
[0003] Traditional driving lights have low efficiency, and their brightness and color temperature are insufficient to meet the lighting needs of complex road conditions, especially in rain, fog, at night, or in low visibility environments. Insufficient light penetration limits the driver's field of vision, increasing driving risks. Furthermore, high-power LED chips or dense light sources generate a large amount of heat during prolonged operation. Poor heat dissipation can lead to accelerated light decay, color temperature drift, and even burnout of the LED chips, resulting in a shortened lifespan. No solutions have yet been proposed to address these technical problems. Utility Model Content

The two light-diffusing elements 4 are arranged in a symmetrical smiling shape. The outer surface has a stepped layering, textured surface, and a bottom heat-fused light-diffusing sheet, forming a terraced light band effect.

[0035] This invention employs an irregular prismatic lens in conjunction with a reflector array to achieve a more uniform light distribution. The reflector array allows for precise light distribution in different zones, eliminating dark areas and light spots in traditional designs. The irregular surface increases the heat dissipation area, which can reduce the LED junction temperature by 15-20℃. The reflector array is beneficial for thermal isolation design, preventing material aging caused by heat concentration. The irregular optical surface can reduce the yellowing and light decay problems common in traditional lenses.
