Agilent HLMP-CW78, HLMP-CW79,
T-1 3/4 Precision Optical
Performance White LED
Data Sheet
Description
This high intensity white LED
lamp is based on InGaN
material technology. A blue LED
die is coated by phosphor to
produce white. The typical
resulting color is described by
the coordinates x = 0.32, y =
0.32 using the 1931 CIE
Chromaticity Diagram.
Package Dimensions
Package Dimension of HLMP-CW78
This T- 1 3/4 lamp is untinted,
diffused, and incorporate
precise optics which produce
well defined spatial radiation
patterns at specific viewing
cone angle.
