Description
These parts are designed for high current operation and high flux output applications. In
order to solve the high temperature produced by the higher current operation, the package’s
design features better thermal management characteristics than other LED solutions coupled
with an efficient optical design.
This package design allows the lighting designer to reduce the number of LEDs required as
well as the overall lighting system cost. The low profile package can be easily coupled to
reflectors or lenses to efficiently distribute light and provide the desired illuminated appearance.
This product family employs the world’s brightest red, red-orange, amber, blue, cyan, green,
and white LED materials etc., which allow designers to match the color of popular lighting
applications, such as automotive lighting and electronic signs.

Note: 1. ØV is the total luminous flux output as measured with an integrating sphere.
2. 1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
3. The dominant wavelength, d is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device.
