LED is short for Light emitting diode that is semiconductor device, when electricity flows through in the forward direction,it emits light of different color. High power LEDs are one type of LED that has higher power and brightness and of course are more costly comparing to the small power LEDs.The regular LED rating current is 20mA,basically LED with rating current higher than 20mA can be called high power LED.Generally rating power has 0.25w,0.5w,1w,3w,5w,8w,10w and so on, the brightness of high power LEDs is measured in lm while for small power LEDs is in mcd,high power LEDs currently are widely applied on automobile lights,flashlights,lighting fixtures etc.
High power LEDs are named corresponds to small power LEDs,the classification standard has three types:
The first type is to classify according to rating power of finish product after packaging,it can be 0.5W,1W,3W,5W,10W….100W.
The second is by package techniques:large dimension epoxy package,simulated superflux epoxy package,MCPCB package,TO package,power SMD package,MCPCB integration package etc.
The third is by luminous decay extent,it can be low and non-low luminous decay high power LEDs.
High power LEDs are energy efficient building block generating
sufficient lumen outputs ideal for popular lighting applications. High power LEDs offer the
best solid-state light source enabling you to figure out the creative ideas about lightings.
The shape of high power leds has available both Star and O'Ring
configurations. Both configurations offer the best possible color rendering
capability and color temperature. With a nominal correlated color
temperature of 3200K, close to traditional indoor light source, it is particularly suited to architects and light designers.
