What is High Power LED

When customers is usually informed by the distributor that their products are high power LED. So, what is high power LED? What is the different between common LED and high power LED? 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. Typical small power LED chips nowadays are SMD5050 and SMD3528. They are widly used in LED fluorescent tubes.

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 led flood light, led downlight, LED 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 superfluxes 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. With a nominal correlated color temperature of 3200K, close to traditional indoor light source, it is particularly suited to architects and light designers.
