Radiometrically Tested AlInGaP LED Lamps
for Sensor- Based Applications
Data Sheet
Description
Radiometrically tested Precision Optical Performance
AlInGaP (Aluminium Indium Gallium Phosphide) LEDs
offer increased sensor-based application design flex-
ibility. High-resolution radiometric intensity bins (mW/
sr) enable customers to precisely match LED lamp perfor-
mance with sensor functionality.
Visible LEDs offer new styling alternatives – light can be
leveraged to develop more attractive products. In com-
parison to invisible infrared sources, safety concerns are
significantly improved by the human autonomic pupil
response and reflexive movement away from bright light.
Visible LEDs further indicate system on/off status.
The AlInGaP technology provides extremely stable light
output over very long periods of time, with low power
consumption.

Note:
1. The dominant wavelength,
Od
is derived from the CIE Chromaticity Diagram referenced to Illuminant E.
2. The radiant intensity is measured on the mechanical axis of the lamp package.
3. The optical axis is closed aligned with the package mechanical axis.
4. The luminous intensity, Iv in candelas, maybe found from the equation IV = IexηV where Ie is the radiant intensity in watts per steradian and ηV
is the luminous efficacy in lumens/watt.
