Description
The HLMP-T200/-T300/-T400/
-T500 light bars are rectangular
light sources designed for a
variety of applications where this
shape and a high sterance are
desired. These light bars consist
of a rectangular plastic case
around an epoxy encapsulated
LED lamp. The encapsulant is
tinted to match the color of the

emitted light. The flat top surface
is exceptionally uniform in light
emission and the plastic case
eliminates light leakage from the
sides of the device.

is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
2. The dominant wavelength,
λ

, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the
color of the device.
3. Radiant intensity, I

Notes:
1. See Figure 5 to establish pulsed operating conditions.
2. For Red, Orange, and Green derate linearly from 50°C at 0.5 mA/°C. For Yellow derate linearly from 50°C at 0.34 mA/°C.
3. The transient peak current is the maximum non-recurring peak current that can be applied to the device without damaging the LED die
and wirebond. It is not recommended that the device be operated at peak currents beyond the peak forward current listed in the Absolute
Maximum Ratings.

The radiation pattern for these
light bar devices is approximately
Lambertian. The luminous sterance
may be calculated using one of the
