1. Why choose case backhoe lamp?
To put it simply, LED case backhoe lamp is brighter than halogen car lights, and more energy-saving, environmentally friendly and long-lived than xenon car lights.
Although the halogen case backhoe lamp is cheap, the light output efficiency is low, the irradiation distance is short, and the light is yellow. Although the light output rate of the xenon case backhoe lamp is similar to that of the LED, the xenon lamp needs a few seconds of waiting time when it starts to reach the full light output, and the service life of the xenon lamp is shorter than that of the LED car lamp.
At present, the technology of LED case backhoe lamp has matured, and there are already LED replacement lamps on the market specifically for entry-level car owners. It is almost the same size and usage as the halogen case backhoe lamp, and can be installed without damage.
2. How to choose LED case backhoe lamp?
The three parameters of case backhoe lamp are mainly brightness (lumens), color temperature and light type.
1.About lumens
The lumen value of the case backhoe lamp is closely related to the brightness. Generally, the higher the lumen value, the brighter the car lights. Many unscrupulous businesses will preach that the high lumen value has proved that the product is very bright, but in fact they did not use the correct method to test and calculate the lumen value. Generally, large manufacturers will use an integrating sphere to comprehensively calculate the lumen value. Integrating sphere is a cavity sphere coated with white diffuse reflection material on the inner wall, also known as luminosity sphere, luminous sphere, etc., used to scatter light from the sample inside the sphere or outside the sphere and close to a certain window Or launch a professional efficiency device for collection.
2. About color temperature
The color temperature of the case backhoe lamp is not as large as possible. Color temperature is a unit of measurement that expresses the color components contained in light. The color temperature of 3500K halogen headlights is low and the light is yellowish. For night driving, not only the lighting brightness is not enough, but also the fatigue of the driver is increased, which is not conducive to night driving. The LED headlights are white light, which can reach the illumination range of night driving, and the human eye looks more comfortable. 7000K xenon headlights, the bright white light is obviously with blue light, the illumination range has been improved, but the penetration is very poor.
3. About light type
The case backhoe lamp light type refers to the angle and shape of the case backhoe lamp. A good light pattern has two important positive effects on car lights:
The first is a clear cut-off line of light type, which is necessary to ensure driving, not to be a high-beam dog. If there is no clear cut-off line, the light pattern will not only be scattered and not condensed, but more seriously, the driver of the oncoming car will feel dazzling and dazzle the eyes when meeting the car, which will affect driving.
