Automotive LED Headlight Lights

① position light. Installed in the front and rear of the car, indicating the presence and width of the vehicle.

② brake lights. Installed in the rear, indicating that the driving car slows down or stops.

③ turn signal. Installed in front, rear and side, indicating the steering of the car.

④ rear fog lamp. Installed in the rear, in order to improve the fog, snow and other inclement weather conditions, the rear of the car to see the situation.

⑤ outline lamp. Mounted in front and rear, logo car exterior.

⑥ parking lights. Mounted on the side, signs the presence of the parked car.

The signal can be used to clearly identify the light signal by other road users at a certain distance. The parameters associated with this lamp are luminous intensity, luminous area, beam diffusion angle and light color. For easy identification of light signals at night with a dark background, the luminous intensity is usually only between a few-and dozens of-and-a-side lights, such as a position light, an indicator and a parking light. For round-the-clock use of lights such as turn signal, brake lights, and so on, the light intensity of the daytime requirements generally up to hundreds of. In order to make this kind of lamp work at night does not produce glare, in addition to limit the maximum luminous intensity, some also use day, night two working conditions. For most of the car signal lights that are close to the senses, the matching between the luminous area and the prescribed luminous intensity must also be taken into account to prevent the brightness from being too large and blinding. Most of the light beam diffuser angle (the angle between the 10% maximum intensity direction), the vertical direction is not less than 20 °, the horizontal direction is not less than 40 °.
