Joeinamillion 0 Posted June 1, 2015 I would like know if it's possible to buy, or make house numbers out of IR lights. Some IR LED glow bright red and I think would make for a great dual purpose covert IR lamp. Any thoughts? Share this post Link to post Share on other sites
jazzar 0 Posted June 4, 2015 from cctvinfo page:- understanding ir lights_ ------------------------------ Infra-red lamps come in varying wavelengths from approx. 730nm to 950nm. 730nm filters are overt and give a red glow - like a traffic light. 830nm filters are semi-discreet and produce a dull red glow. 950nm filters are effectively totally covert - giving off no visible illumination. Viewing distances are reduced with 830nm and 950nm lamps. A 950nm will require a highly sensitive night time camera. ------------------------------ you could check on ebay for suitable led diodes and get a electronics guy to link them up in the shape of your number throw in a light sensor switch so it only comes on at night- you would need to encapsulate the unit for weatherproofing and supply power to the unit. - Anything can be done - but will it be worth the cost- or does the cost matter if its what you would like - then go for it.

Owain 0 Posted June 8, 2015 you could adapt this PCB http://www.bigclive.com/flud.htm just put in the LEDs you need to make the outline of the digits. Maybe poke them through a layer of black plastic to provide a background to improve the contrast Share this post Link to post Share on other sites
