What Is the Difference Between LED High -power and Small Power?

The single power of the high -power LED light is higher, the brightness is brighter, and the price is higher. The rated current of small power LED lights is 20mA, and the rated current can be counted as high power with a rated current higher than 20mA. The general power number is: 0.25W, 0.5W, 1W, 3W, 5W, 8W, 10W, etc. The main brightness unit is LM (lumen), and the brightness unit of small power is generally MCD. These two units cannot be converted. At present, as an emerging green, environmental protection, energy -saving light source is widely used in car lights, flashlights, lamps and other places. The reason why high -power LED lights are called this is mainly for small -power LED lights. There are three types of classification standards: the first of which is to be divided into 0.5W, 1W, 3W, 5W, 10W . .100W is different, according to the total power of the molding product after packaging. The second type can be divided into: large -sized epoxy resin packaging, imitating mermaid epoxy resin packaging, aluminum packaging, aluminum, aluminum, and aluminum. The third type of substrate (MCPCB) encapsulation, To packaging, power -type SMD package, MCPCB integrated package, etc. The third type can be divided into low light aging power products and non -low -light aging power products according to its degree of light aging. Of course, because there are many parameters of the high -power LED light itself, there will be different classification standards according to different parameters. High -power LED lights still belong to one of the LED packaging products, which is the most important part of semiconductor lighting towards the field of ordinary lighting. When using high -power LED lights, you must understand the light distribution of light distribution, color temperature distribution, thermal resistance and color rendering to master the light -intensity distribution map of the W -class high -power LED light. It is necessary to correctly use the high -power LED light. Manufacturers must provide customers with various parameter indicators of LED devices whether the color temperature distribution of high -power LED lights is evenly distributed, which will directly affect the lighting effect; and the color temperature and color rendering index are interconnected, and the change of color temperature will cause changes in the color rendering index. The thermal resistance of high -power LED light directly affects the heat dissipation of LED devices. Low thermal resistance, the better the heat dissipation; the heat resistance is poor, so that the temperature of the device will rise, which will affect the wavelength drift of the light. According to the experience, the temperature rises once, and the light wave length should drift by 0.2 0.3nm, which will directly affect the luminous quality of the device. Excessive temperature rise also directly affects the service life of the W -level high -power LED energy -saving lamp. Coloring is an important indicator of white light LED. The color of white light LED for lighting must be above 80 or more.
