Application of led chip high power

1.Roadway lighting: Street light, Garden light, Tunnel light
2.Indoor ligting: Spot light, Ceiling light bulb and so on.
Architectural lighting landscapes, lighting exterior illumination, etc.
Wall lamps, underwater lamps, decorative illumination, and more Underground lamps,reading lamps, emergency lights, and interior illumination Miner's lamps, flashlights, and car lamps.


Cautions 1w high power led chip, 3w high power led chip

1)Soldering Conditions

Number of reflow process shall be less than 2 times and cooling process to normal temperature is required between first and Second soldering process.


2)Static Electricity

It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.All devices, equipment and machinery must be properly grounded.Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower, or the LEDs do not light at the low current. Criteria : (VF > 2.0V at IF=0.5mA)
