Car Side Step Light LED Light Running Board Light for Toyota Alphard Vellfire

Product description

The function of the side lights of the body is: mainly to help distinguish whether the distance on both sides of the road is suitable for passing, and to judge the distance on both sides of the car when overtaking and meeting. The side light is a kind of warning light, which is installed on the edge of the top of the car. When it is raining, snowing, foggy or other poor visibility, the side light can remind the passing vehicles.

The direct lighting mode means that the LED light is directly irradiated by the light diffusion plate, and the light source is distributed on the back; while the side lighting means that the LED light source is distributed on the four sides, and the light passes through the light guide plate with high light transmittance to form a uniform plane light emission Effect. The light of the direct-type LED panel light needs to be irradiated directly, and it must be emitted through a diffuser plate with a certain thickness, plus the space required to eliminate bright spots, so the direct-type LED panel light must be high in power and thickness, which is insufficient No wonder.

2 Brightness of side-light panel lights VS brightness of direct-type panel lights Direct-type panel lights have great advantages in brightness and light efficiency, and can easily reach more than 4200Lm. The light of side-emitting LED panel lights is from the side of the light guide plate through the light guide plate Under the action of reflection and refraction such as reflective dots, reflective plates, etc., when the light is emitted from the front, its light output efficiency must be lost to a certain extent in each path of its light transmission, so its brightness is often slightly insufficient. As an indoor lighting fixture, in addition to brightness, light quality is also getting more and more attention. It directly affects comfort and human health, and is a key factor in judging the quality of LED panel lights. The color temperature of LED panel lights on the market is generally bluish, and the color rendering index is about 70.
