With the improvement of living standards, the proportion of China's per capita ownership of cars is also climbing year by year the public's requirements for car is also getting higher and higher. Compared with traditional halogen and xenon lights, projector led lights are gradually appearing in the public eye and are loved by the public for their advantages.

Why choose projector led lights?
In a nutshell, high power projector led lights are brighter than halogen lights and more energy-efficient and environmentally friendly than xenon lights.
Halogen lights are cheap, but the light output efficiency is low, the irradiation distance is short, and the light is yellow. Although the light output rate of xenon car lights and projector led lights are about the same, xenon lights need a few seconds of waiting time to reach full light output when starting, and the life of xenon lights is also shorter than projector led lights.
Projector led light technology has matured and there is already projector led light replacement lights on the market specifically for entry-level car owners, which are almost the same size and usage as halogen lights and can be installed without damage.
How to choose projector led lights?
LED three parameters are mainly brightness (lumens), color temperature, and light type.
Lumen
The lumen value is closely related to the brightness, usually, the greater the lumen value the brighter the projector led light, many bad businessmen will advocate high lumen value has sought to prove that the product is very bright, but in fact, they do not use the correct method to test and calculate the lumen value. Generally, large manufacturers will use the integrating sphere to make a comprehensive calculation of the lumen value. Integrating sphere is a cavity sphere coated with white diffuse reflective material, also known as the luminosity ball, light through the ball, etc., used to be in the ball or placed outside the ball and near a window of the specimen on the scattering or emission of light to collect professional efficiency devices.
Color temperature
Color temperature is not the larger the value, the better. Color temperature is a unit of measurement that indicates the color component contained in the light. 3500K halogen headlamp color temperature is low, the light is yellow, for night driving, not only lighting brightness is not enough, and increase driver fatigue, not conducive to night driving. Projector led lights, positive white light, can reach the irradiation range of night driving, and the human eye looks significantly more comfortable. 7000K xenon headlights, bright white light obviously with blue light, the irradiation range has improved, but the penetration is very poor.
Light type
The car projector led light type refers to the angle and shape of the car projector led light to play out. A good light type has two important positive effects on the lights.
One is a clear light type bright and dark cut-off line, which is necessary to ensure that out of driving, do not do far light dog. If there is no clear light and dark cut-off line, the light type is not only more scattered not concentrated, more serious is, when the meeting of the opposite direction of the driver feels harsh, shaking eyes, affecting driving.
Second, a good light type is more beneficial to the pavement far and near, can illuminate a wider road in front of the car, the driver will have a wider left and right field of vision, the sudden appearance of people or animals from both sides of the vehicle at night can be found in time. Based on meeting the clear bright and dark cut-off line, as far as possible to make the front of the car 50 meters to 75 meters distance bright and clear, can help the driver to find the obstacles earlier, the closer to the front of the car the longer and wider the beam, the wider the irradiation range the better.
