Features
High-power LED energy-saving lamps are still one of the LED packaging products, which is the most important part of the semiconductor lighting industry.
When using high-power LED energy-saving lamps, you must understand the issues of light intensity distribution, color temperature distribution, thermal resistance and color rendering.
Mastering the light intensity distribution map of W-class high-power LED energy-saving lamps is necessary for the correct use of high-power LED energy-saving lamps. Manufacturers must provide customers with a variety of LED devices
Parameter index
Whether the color temperature distribution of high-power LED energy-saving lamps is uniform will directly affect the lighting effect; and the color temperature and color rendering index are related to each other, and the change of color temperature will cause the change of color rendering index.
The thermal resistance of high-power LED energy-saving lamps directly affects the heat dissipation of LED devices. The thermal resistance is low, the better the heat dissipation; the higher the thermal resistance, the lower the heat dissipation, so that the temperature rise of the device will affect the wavelength drift of the light. According to experience, when the temperature rises by one degree, the wavelength of the light should drift by 0.2~0.3nm, which will directly affect the illuminating quality of the device. Excessive temperature rise also directly affects the service life of W-class high-power LED energy-saving lamps.
Color rendering is an important indicator of white LEDs. The color rendering of white LEDs used for illumination must be above 80.
