White LED in 3mm T 1 Waterclear Package
TLHW490.
Vishay Semiconductors
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.
