Hi
I have a DLP LightCrafter Evaluation Module (EVM) and I only need output from one of the LEDs. (I am doing Phase Shifting Profilometry.)
I don't have active cooling so I set e.g. the red LED current value to 274 giving an LED current of 633mA. This is however not enough output for my application.
When I never uses more then one LED at a time, can I then using only passive cooling set the output of e.g. the green and blue LED to zero and e.g. the red LED current value to 274*3=822 giving an LED current of 1899mA?
I is important to note that I only flash the LED for a very short time and then have a short pause before showing the next pattern.
The different scenarios are as followes:
- Light on for 18ms, pause 784ms, repeat 12 times, stop for at least six seconds and in most situations several minutes.
- Light on for 18ms, pause 460ms, repeat 30 times, stop for at least six seconds and in most situations several minutes.
- Light on for 150ms, next pattern, light on for 150ms, repeat 12 or 30 times, stop for at least six seconds and in most situations several minutes.
How do I get more light output in the above described situation?
Thansk.
Best Regards
Kristian
