DESCRIPTION

High Intensity LED with typical color coordinates
x = 0.33, y = 0.33 (typical color temperature 5500 k).
This LED emits white light with a high color rendering
index.

The emission spectrum is tuned for ideal white, without

APPLICATIONS

• Indicator and backlighting

• Indoor and outdoor message panels

• Alternative to incandescent lamps

• Marker lights

the impression of being blue shaded or "cold". The
package is a standard 3 mm.

The internal reflector is filled with a compound of TAG
phosphor and an elastic resin.

Therefore the chip is better protected against temper­ature cycle stress.

The phosphor converts the blue emission of the InGaN
chip partially to amber, which mixes with the remaining
blue to produce white.
