LITE-ON TECHNOLOGY CORPORATION
Property of Lite-On Only
1. Description
The LTPL (LiteOn Power LED) is a revolutionary, energy efficient and ultra compact new light source,
combining the lifetime and reliability advantages of Light Emitting Diodes with the brightness of
conventional lighting. It gives you total design freedom and unmatched brightness, creating a new
opportunities for solid state lighting to displace conventional lighting technologies.
Features

Luminous flux is the total luminous flux output as measured with an integrating sphere.
The chromaticity coordinates (x, y) is derived from the CIE 1931 chromaticity diagram.
IS CAS140B is for the luminous flux (lm) and the CIE1931 chromaticity coordinates (x, y) testing.
The chromaticity coordinates (x, y) guarantee should be added ± 0.01 tolerance.
