What's the best led headlight bulb?
Automotive luminaires are important components related to vehicle and personal safety. They are “car eyes”. Leishen LED auto bulbs Zero-second lighting, waterproof and shockproof, high temperature resistant,anti-low temperature, and tangential perfection. 8 Testing before packing.
1.High temperature testing.
Leishen best led headlight bulb 2018 was placed in a high temperature test chamber for 72 hours and the temperature was controlled at around 90°. After 72 hours of high-temperature baking, we opened the test chamber and the lights were intact and very bright. Maintain brightness while maintaining high temperatures.
2. Low temperature resistance testing.
Leishen best led headlight bulb 2018 is placed in a container cup filled with water and placed in a low temperature test chamber for 72 hours at a temperature of about -40°. After 72 hours, bulb still can work.
4. Seismic Testing
In the case of poor road conditions, high-quality lights can withstand strong earthquakes and the lamp beads do not fall. The lights are fixed on the seismic tester, energized to make the lights work, and the equipment is turned on. During the test, we saw that the Leishen best led headlight bulb 2018 kept working normally during strong earthquakes, the lights did not fall, and the lights did not flash.
During the driving, the electric charge generated by the mechanical movement of the bumps. If the bulb is not resistant to static electricity, the electrostatic discharge will affect the performance and life of the lamp.
6.Color Temperature testing
The color temperature of the best led headlight bulb 2018 is close to 6000K, and the color temperature is white and yellow, soft and not glare.
7. Light Distribution Performance Testing
"Light distribution performance" is the most important performance indicator of the bulb, which can be understood as the luminous intensity of the lamp in each plane.
During the test, the probe remains stationary and the luminaire rotates about the vertical and horizontal axes to obtain the light intensity distribution throughout the space. Under computer control, the measured best led headlight bulb 2018 has a horizontal rotation range of ±180° and a vertical rotation range of ±90°. The photometric probe measures the luminous intensity of the bulb in all directions on the plane. When a plane is measured, the horizontal axis motor drives the luminaire to rotate through an angle, and then the photometric probe measures the light intensity distribution on the other plane. Through the vertical spindle.
Leishen best led headlight bulb 2018,Plug and play. There is no delay in lighting, the brightness is higher than the original car halogen lamp, and the spot scattering range is relatively large, and there is also a clear spot in the middle. Such a bulb is clearly seen in front of the lamp, and there is also light illumination on both sides of the field of view. The tangent is also more obvious and the light type is good.
