LEDs for scoreboard.

[eddieg]

Hi. I built a large 12" digit scoreboard 3 years ago and it has worked well. The only problem with it is the LEDs have a 60 degree veiwing angle. I would like to change these to 120 degree so they can be seen better. My problem is I can not find any to buy off the shelf. Can anyone help me locate what I want. The leds I used where 10mm red made by kingbright 577-768.
Thanks Eddie.

It seems to be the 10mm that is the problem. Most have the same lead spacing (2.5mm) so try looking for 120 degrees in another package size.

If you go from 60 to 120 degrees the light will be much dimmer.

If you coat LEDs in a white crystalline substance they will be visible at a wider angle. Just try wetting one with saliva and dipping it in sugar to see how this works. Obviously sugar is not a long term solution but other white crystalline substances may be.

A sanding drum on a dremel gives the same effect, if you have time, spose that'd still be quicket than unsoldering them all.

I have done similar in the past with a dob of clear epoxy resin (double bubble) on top.
