Description
These 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/-
3960/-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

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. The dominant wavelength,
d
, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the
color of the device.
2. The radiant intensity, I
e
, in watts per steradian, may be found from the equation I
e
= I
V
/
V
, where I
V
is the luminous intensity in
candelas and
V
is the luminous efficacy in lumens/watt.
