The HN series LED headlamps are developed specifically to improve the safety of all-day lighting for heavy trucks. They integrate high-power LED chips, integrate multiple LED light sources in a single lamp, and have a light flux of up to 4,000, significantly exceeding the brightness of traditional halogen lamps, and effectively enhance the clarity of the field of view at night and in rain and fog road conditions. Its color temperature is optimized to 6,500 K natural white light, which combines low glare and rain and fog penetration to reduce driving fatigue.The lamp body is made of aluminum die-casting shell and hardened glass lampshade, supporting IP6K9K level protection, impact resistance, dust and water resistance, and integrated thermal management system and deicing function, which can cope with the harsh environment of -40 °C extreme cold or dust, to ensure the stability of extreme operating conditions.With a voltage of 24 V, power consumption of only 56 W, energy saving and a life of up to 50,000 hours, significantly reducing fleet maintenance costs. The design retains the original vehicle interface, supports lossless installation, and has passed international certifications such as ECE-R10 to ensure compliance and vehicle safety.
