Description
The source color light emitting diode dice of these devices is
made of AlInGaP on a transparent substrate (TS).
The water clear epoxy lens on these devices create viewing
angles of 22 and 30 degrees that match international
specifications for traffic sign utilization.
These LED lamps provide superior endurance against
moisture and high temperatures thus are reliable for outdoor
environment use. With a lower power consumption than
traditional incandescent lamps, these devices yield lower
system cost.
Features
* High luminous intensity output.
* Low power consumption.
* High efficiency.
* Versatile mounting on PCB or panel.
* I.C. Compatible / low current requirements.
3
* Popular T-1
4
diameter (5 mm).
Applications
* Traffic signals.
* Versatile warning signals.
* Outdoor traffic display panels.

NOTE:
1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
eye-response curve.
2.
θ
1/2
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
3. Iv classification code is marked on each packing bag.
4. The dominant wavelength,
λd
is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device.
