White LED in 3mm T 1 Waterclear Package

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, with-

out the impression of being blue shaded or "cold". The

package is a standard 3mm.

The internal reflector is filled with a compound of TAG

phosphor and an elastic resin.

Therefore the chip is better protected against temper-

ature cycle stress.

The phosphor converts the blue emission of the

InGaN chip partially to amber, which mixes with the

remaining blue to produce white.
