COB LED

THE ADVANTAGES OF COB LED

LED chip is fixed on aluminium layer of aluminium base PCB.The heat from chip can be spread out through aluminium layer rapidly.

Low lighting decay,decay less than 3% after 1000 hours.

Equable and soft irradiancy,no glaring and eye Protection,

Good reliability,no dead bulb and no motting.

LED full lighting module can be combined into different LED lights easyly.

Highly Color-rendering index and lighting effect.

Safty,Environment friendly.

Driving Circuit

As high power LED lamp bead complies with the diode VI characteristic curve, if the floating current with the floating voltage could damage the led bead, that suggest customer using constant current power or IC, not using constant voltage power or IC. The LED lamp bead can’t be drove reverse.

Storage Conditon

A. Before open the package, the LED lamp bead could be stored below 30°C/90%RH. After open the package, the LED lamp bead should be used in 30°C/70%RH;

B. Should be used in 168hrs (7days) after open the package;

C. LED lamp bead with lens should be used with dustproof measures;
