Question: Are there any collimators for luxeonstars that redirect output 90 degrees?
In other words, something like a narrow angle optic with a prism or mirror @ 45 degree angle, at the end of it.
Or perhaps a very efficient light pipe?
I'm tinkering with some old 1W 'Stars for use as 'city lights' in my car's headlight assemblies. If you're not familiar with the term since we don't have them in USA/Canada market cars, found mainly in cars in Europe... They are low wattage incan bulbs installed in the headlight reflector shells. Turned on with the parking lights. Improves your visibility, plus the added bonus of keeping the headlight shell illuminated in case of a main headlamp failure.
Since the heat from the halogen filament would kill a LED, the standard mounting of a hole close to the main bulb is out of the question. I was thinking of 'piping' the light in from beneath and forward. With the point source shining back at the reflector. Similar to the concept of Pelican's LED flashlight for firefighters.
The LED would be thermally isolated, yet still use the reflector, albeit not efficiently, (or more efficiently, who knows).
