• Core function: Through the condensation and refraction of the lens, the scattered light emitted by the light source (such as LED or xenon bulb) is concentrated and projected, forming a clear cut-off line between light and dark, greatly improving lighting efficiency and paving effect.
• Structural composition: Typically consisting of an optical lens, a reflective cup (or reflective bowl), a bracket, a dimming mechanism (dual-light lens), and a fixed component, it forms a complete optical system.
• Light pattern standard: It should be able to form clear cut lines between light and shadow, avoid dazzling scattered light, comply with automotive lighting safety standards, and ensure that oncoming drivers are not disturbed when meeting.
• Dual-beam switching: The dual-beam lens kit incorporates an electromagnetic valve that switches between high and low beam modes via a baffle, enabling a single light source to simultaneously provide both high and low beam functions. It responds quickly and has a compact structure.
• Light-concentrating efficiency: Compared to traditional reflectors, the lens kit has a higher light energy utilization rate, effectively projecting most of the light onto the road surface and reducing light loss caused by diffuse reflection.
• Brightness enhancement: When paired with high-power LED or xenon light sources, it can significantly increase road illumination, expand the illumination distance and width, and enhance the safety of nighttime driving.
