Luxury design Car Led Tail Light for Toyota Sienna 2021

Product Description

When driving at night, the tail lights indicate that there is a car in front of the rear car, and show the positional relationship between the two workshops, so they are installed on both sides behind the car. Japan's safety regulations are the same as the European standard ECE7. The luminous intensity near the center is 4~12 cd, and the light color is red.
Design Principles of Automobile Tail Lights
1. It has sufficient luminous intensity so that the taillights of the car can clearly distinguish the signal for drivers of other vehicles or pedestrians even in bright sunlight.
2. When driving at night, the light from the taillights will not cause glare and discomfort to drivers of other vehicles or pedestrians.

The development trend of automobile taillights
An ideal tail light should have the following characteristics:
(1) High luminous intensity and reasonable light intensity distribution;
(2) Fast luminous rising front time;
(3) Long life, maintenance-free, low energy consumption;
(4) The switch has strong durability;
(5) Good resistance to vibration and shock.
At present, the light sources used in automobile tail lights are mainly incandescent lamps, and some new light sources such as light-emitting diodes (LEDs) and neon lights have also appeared.

Classification of car tail light sources
incandescent light source
The incandescent lamp is a thermal radiation light source, the filament is heated to be incandescent by electric energy and emits light, and the light emitted is a continuous spectrum. The traditional car tail light with incandescent lamp as light source is mainly composed of four parts: incandescent light source, single parabolic reflector, filter and light distribution mirror. The incandescent lamp has a simple structure and is easy to use. It is the most commonly used light source, and its output is stable, and the change with the ambient temperature is small.
Light Emitting Diodes (LEDs)
The principle of the light-emitting diode is that the junction diode is in a forward biased state, the electrons in the N region and the holes in the P region pass through the PN junction, and the electrons and holes recombine to emit light.
neon light source
The principle of the neon light source is to apply an electric field at both ends of the discharge tube filled with inert gas to generate continuous discharge. In this process, the excited inert gas atoms release photons to emit light when they return to the ground state. Filling different inert gases can emit light of different colors.
