I’m trying to source some LEDs for a current project - to be mounted on a power kite. LEDs will be controlled using Arduino. The LEDs will need to have a good ratio of luminous intensity to forward voltage to keep the weight of the power supply down. They should also have a wide viewing angle.
I’m new to LEDs so am not sure what is available - so far I’ve been looking at some LEDs at Maplins which are advertised as being 1900-3000mcd, with a forward voltage of 2.3-2.6V. Viewing angle is 15 degrees. Can I improve on this?
I’m also looking at options of mounting LEDs in clusters to improve brightness / angle (if mounted in a circular array). Another possibility is to use a small spherical diffuser - like a ping pong ball, but smaller. Again I don’t know what products are available.
I’d be grateful for any suggestions for products / suppliers (ideally in the UK). Any details/ingenious solutions would also be welcome!
