In this part finder, we wanted to highlight Infrared (IR) LEDs. We have two we use in the TV-B-Gone kit – one is a narrow beam (20 degree) and one is a wide beam (40 degree). For ‘night vision’ illumination, we think the wide beam may be a little more useful. For IR remotes and such, check out the narrow beam.
One thing about IR LEDs to watch is that they are designed for high power use. Whereas most LEDs dont like more than 20 mA drive current, IR LEDs can often take 100 mA constant current! Not only that but for pulses (such as remote control signals) the max current is a blistering 1000 mA!
NEW PRODUCT – Super-bright 5mm IR LED (25 pack) – 940nm. Infrared LEDs are used for remote controls (they’re the little LED in the part you point at your TV) and ‘night-vision’ cameras, and these little blue guys are high powered ones! They are 940nm wavelength, which is what nearly all devices listen to. They’re 20 degree beamwidth, and work great for any kind of remote control application. This is a pack of 25!
