Heshan Jianhao Lighting Industrial Co., Ltd.
Automobile device for giving light, especially one that has a covering or is contained within something. Lighting should be provided with good lighting and should minimize glare. For the headlamp, in order to meet the above two requirements, use the two conditions of distant light and near light. The distant light is a long distance light beam that is used in the front of the car or not following other cars. It is generated by the main filament in the focal point of the reflector and the power is large, and the beam direction is approximately horizontal. In order to ensure the safety of driving, the distance of light distance (detection and identification of obstacles) should be greater than the braking distance to realize the timely parking. The speed limit is applied in most countries, given that the required distance light intensity is proportional to the four times of the speed.
