Technical Data
P/N BL-42D0-0304
Note 1. Optical and electrical specifications are given for the specified drive current at a 25 C junction temperature.
Note 2. Operating temperature is for LED die junction. Lower temperatures improve lumen maintenance.
Light Output Characteristics
Luminous Flux vs. Current
Luminous Flux vs. Current
When operating at drive currents higher than test currents indicated do not exceed maximum recommended junction temperature.
Higher drive currents will increase luminous flux but also increase thermal load. Without proper heat sinking, lower efficacy (lumens per
watt) and lower lumen maintenance may result. For dimming significantly below test currents indicated, pulse width modulation is
recommended for maximum consistency and stability of light properties.
Luminous Flux vs. Junction Temperature
Light output from LED die will decrease with increasing junction temperature. This effect is particularly acute for die in the 580 to 750
nm range. As a result it is recommended that the LED array heat sink design be optimized to maintain the die junction temperature as
low as possible.
