Optical Considerations
The light output of the LEDs is inversely related to the LED diode’s
junction temperature as shown in Figure „Normalized Luminous
Intensity vs. Junction Temperature“. For optimum light output, keep
the thermal resistance of the socket or PC board as low as possi-
ble.
Normalized Luminous Intensity vs.
Junction Temperature
When mounted in a 10°C/W socket and operated at Absolute Max-
imum Electrical conditions, the HDSP200XLP will show an LED
junction rise of 17°C. lf T
Under these conditions the following figure shows that the I
be 75% of its 25°C value.
