I want to put yellow leds inside the turning-signal cases used in motorcycles.
The problem is: since the case is not deep enough, when I look from far I can only see the focused, pin shaped LED sources (two, in my case).
The leds I am using are like these:
As I see it, the case from the motorcycle turning light is supposed to receive the an incandescent lamp, so the internal diffusions gives its whole area the same brightness as seen from far away.
So my question is: how should I "unfocus" these leds (which I already bought, by the way)?
Possible options would be:
- Cover the led "lens" with some "cap" made of a diffusing material (semi-transparent glue?). Possible problem would be loss of effective luminous power?
- Paint the led lens with some suitable diffusing paint or material?
- Sand the led lens surface, so as to scatter the light?
- Reshape the so that it distributes the light in more directions?
I know I could try every option myself, but I imagine this is not a rare situation, so perhaps someone has already done something about it.
