High-power LED and the difference between low-power led

led light-emitting diode is a diode, characterized the current time is the wizard of light to emit different colors. Led high power led is a kind, as opposed to low-power led, the power led single higher power, brightness, brighter, higher prices. Low-power led is rated 20mA, 20mA rated current higher than can be counted as high-power basically. There are a few general power: 0.25w, 0.5w, 1w, 3w, 5w, 8w, 10w and so on. Main unit of luminance is lm (lumens), low-power unit of luminance is generally mcd. The two units can not be converted. Now emerging as a green, environmentally friendly, energy-saving light sources are widely used in car lights, flashlights, lamps and other places.
LED high power so called, mainly for low-power LED light, I summarize the current classification criteria, there are three:
The first one is based on the size of the power can be divided into 0.5W, 1W, 3W, 5W, 10W .... 100W range, depending on the package after the molding products in terms of total power varies.
The second process can be divided into its packaging: large epoxy resin, imitation of piranha-type epoxy resin, aluminum plate (MCPCB) type package, TO package, power-type SMD package, MCPCB integrated package, etc.
A third of its lumen can be divided into different levels of high-power low-light decay products and non-high-power low-light decay products.
Of course, since the parameters of high-power LED itself more, according to different parameters have different classification criteria, no class in this state. LED high power LED packages are still in a kind, is to make the semiconductor lighting. Into the general lighting in the most important part.
