LED is the abbreviation of Light Emitting Diode. The Chinese translation is light-emitting diode. It is similar to energy-saving lamps at home. It used to be used in taillights, turn signals, and daytime running lights. Due to its outstanding advantages, it is now more and more. In the car models, LEDs will be used as car headlights. Its optical structure is similar to that of xenon lamps. The LED light can be converged into parallel light through reflection and lens.

The advantages of LED headlights are obvious. (1) Energy-saving, its luminous efficiency is high, and its energy consumption is only one twentieth of the traditional halogen lamp; (2) Long service life, LED service life can reach about 50,000 hours. It is almost twice as long as the 30,000 hours of xenon headlights; (3) The application is high, because the electronic components have good shock and shock resistance, and can be used in a variety of environments; (4) Small size, almost smaller LED components It can meet the layout and shape design of various lamp factories; (5) Fast response speed, LED lighting is at the level of microseconds; (6) Brightness attenuation is small, and LED brightness attenuation is much smaller than halogen lamps; (7) and use environment requirements Low, the LED unit can be driven only by low-voltage DC, and the load is small, unlike the xenon lamp, it also needs a boost device. Its disadvantage is that the price is relatively high, and the heat dissipation problem is not easy to control.

Halogen headlights

Halogen headlights are one of the most common car headlights currently used in automobiles. Halogen headlights are actually improved incandescent bulbs. In fact, halogen gas is added to the incandescent bulb. The addition of halogen gas can make the halogen bulb more durable than the incandescent bulb. Because the direction of the halogen bulb is omnidirectional, it belongs to the astigmatic light source. The reflector is used to gather the light, so we usually use the halogen lamp as the light source, and the lamp group that gathers the light through the reflector is called the reflective halogen lamp. The light color of halogen headlights is yellowish, so it is also called candle light.
