Description

These clear, non-diffused lamps

out-perform conventional LED

lamps. By utilizing new higher

intensity material, we achieve

superior product performance.

The HLMP-3750/-3390/-1340

Series Lamps are Gallium

Arsenide Phosphide on

Gallium Phosphide red light

emitting diodes. The HLMP-3850/

-3490/-1440 Series are Gallium

Arsenide Phosphide on Gallium

Phosphide yellow light emitting

diodes. The HLMP-3950/-3590/

-1540/-D640/-K640 Series Lamps

are Gallium Phosphide green light

emitting diodes.

Notes:

1. See Figure 2 to establish pulsed operating conditions.

2. For Red and Green series derate linearly from 50°C at 0.5 mA/°C. For Yellow series derate linearly from 50°C at 0.2 mA/°C.

3. The transient peak current is the maximum non-recurring peak current the devices can withstand without damaging the LED die and

wire bonds. It is not recommended that the device be operated at peak currents beyond the Absolute Maximum Peak Forward Current.

NOTES:

1. ALL DIMENSIONS ARE IN MILLIMETERS (INCHES).

2. AN EPOXY MENISCUS MAY EXTEND ABOUT 1 mm (0.40") DOWN THE LEADS.

Notes:

1. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the

color of the device.

2. The radiant intensity, Ie, in watts per steradian, may be found from the equation Ie = IV/ηV, where IV is the luminous intensity in

candelas and ηV is the luminous efficacy in lumens/watt.
