temperature compensated LED driver
temperature compensated LED driver
(OP)
Hi guys:
I'm developing a colorimeter using a LED as a light source. After building my first prototype and testing I've found that I'm getting slight changes in luminous intensity from the LED with changes in ambient temperature. Before I try to develop a temperature compensated LED driver I was wondering if anyone new of any already on the market. If not does anyone have any suggestions for a circuit.
Thanks,
Pete

A well-designed instrument uses both thermal stabilized LEDs and current source.
