infrared camera ratings
Infrared Flashlight is motorized?
I need help on questions I made a flashlight with infrared LEDs. I saw one somewhere that you can see make sudo night with ILEDs and a digital camera. So I replaced 8 LEDs from a flashlight Walmart $ 4. It works, but only a few inches. The how is it had the whole room. How can I brighten. I removed the resistance of the torch. I also tried a 9V battery. The torch was originally used 3 AAA batteries, which I would how to use ... The tech specs ILEDs Normal: Radiant Power (100mA): 16mW min Forward Voltage: 1.2V forward current: 100mA Absolute Maximum Ratings: Forward Voltage (20 mA) 1.6V Reverse: 5V Forward Current: 1.2A Reverse: 10μA Wavelength: 940 nm, use easily understood language ... if you can ...
I'm guessing the light had two diodes in series x 4 in parallel. I'm not sure whether the AAA battery can continuously supply 400 mA - I know that the 9V battery can not. Are you sure they fit well with your digital IR cameras reaction? Do you have the same equipment that the original system had? It may be that your camera is just not that good in the IR range and one in the demo is good with the wavelength of the IR light from the diodes. To "remove" the resistance. Did you replace it with a short? Do you have a low inductance connection such as braid connection (400 mA is a fair amount the current) or something like 30 Gauge Kynar? You probably do not want to eliminate the resistance, unless you want your ILEDs destroy. You may need to change the value to approximately 2.5 ohms, so 400 mA to fall about 1 V across the resistor.
