Innovation Solution
A primary optical structure for vehicle lamps that includes a reflection unit and a shading structure, allowing for adjustable light and shade cut-off lines to form a dark area, enabling precise control over the high-beam light shape to prevent dazzling, with the shading structure being integral to the reflection unit and using a heat sink for thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If mechanically rotating light-shielding rollers are used to form a dark area, then dazzling is prevented, but the system structure becomes very complicated
Solution Approach 1:
The invention extracts the light-shielding function from the complex mechanical rotating roller system and integrates it directly into the reflection unit's structure. The reflection unit itself forms the dark area through its geometric design, eliminating the need for separate mechanical light-shielding components and their driving mechanisms.
Solution Approach 2:
The invention merges the light-shielding function with the reflection unit structure. The reflection unit is designed to naturally create a dark area in specific directions without requiring additional mechanical components, combining multiple functions into a single integrated structure.
2Device complexity
If fixed widening angles are used for left and right lamps, then the structure is simple, but the illumination range cannot be adjusted to match vehicle camera detection range
Solution Approach 1:
The invention makes the light distribution characteristics adjustable by controlling the illumination intensity of multiple light sources independently. The system can dynamically adjust the illumination range and dark area position to match different driving scenarios and vehicle camera detection ranges, transforming a static structure into a dynamically adaptable system.
Solution Approach 2:
The invention changes the parameters of light sources (illumination intensity, activation state) to achieve different illumination patterns. By adjusting these parameters, the system can adapt the illumination range and dark area formation to various detection ranges and driving conditions without changing the physical structure.
3Area of stationary object
If the illumination range is larger than the vehicle camera detection range, then more area is covered, but dazzling is caused to vehicles outside the detection range
Solution Approach 1:
The invention applies different illumination intensities to different spatial regions by independently controlling multiple light sources. The system creates a localized dark area in directions where vehicles outside the detection range might be located, while maintaining full illumination in other areas, thus preventing dazzling only where necessary.
Solution Approach 2:
The system uses vehicle camera detection range as feedback to determine the appropriate illumination pattern. Based on this feedback, the control system adjusts which light sources are activated and at what intensity, dynamically forming dark areas in directions outside the detection range to prevent dazzling while maintaining illumination within the detection range.
4Object-affected harmful factors
If high-beam lamps are switched to low-beam lamps to prevent dazzling, then other vehicles are not disturbed, but the driver cannot see as far as possible
Solution Approach 1:
The invention segments the high-beam illumination into multiple independently controllable light sources arranged in arrays. This segmentation allows the system to activate only the necessary light sources for current driving conditions, creating a dark area in directions where other vehicles are located while maintaining high-beam illumination in other directions, thus preserving long-distance visibility without causing dazzling.

AI summary
Disclosed are a primary optical structure, a high-beam lighting device, and an anti-glare high-beam light. The primary optical structure comprises a reflection unit and a shading structure located in front for blocking part of the reflected light from the reflection unit. The primary optical structure is configured for use in a left vehicle lamp or a right vehicle lamp, where the shading structure is arranged at a left side portion or a right side portion of the lamp, respectively. The light blocked by the shading structure and the light that is not blocked are bounded by a right side edge or a left side edge respectively, and an upper side edge of the shading structure. In a vehicle lamp, the primary optical structure can form a high-beam profile having a dark area to prevent glare, such that the dark area formed has an adjustable width and position, improving driving safety.
