The design of an early foglight LED board has begun. mepstein sent me a couple of foglight fixtures to use to design the board. 2 main issues are fitment and heat dissipation. If things work out ok the design should be able to be re-laid out for the later square foglight.
The board will have 8 Cree XP-G3 high power surface mount LEDs with 350ma current each. These will burn about 1W of power with a total power dissipation expected to be less than 10W. Hopefully these will be almost as bright as a headlight. Each LED will have its own focusing lens. The lenses are Carclo 10192 elliptical 20mm lenses. The light pattern for the 10192 lens is shown below. This is the spectral dispersion for the lens. |

This is great, thanks. I posted some lens pictures at:
http://www.914world.com/bbs2/index.php?sho...=233202&hl= The early and late lenses have different heights, is that what you meant when you said "early?" More importantly, will this affect the LED project?? I LOVE visibility and have ALL of your stuff!! Paul |

More importantly, will this affect the LED project?? I LOVE visibility and have ALL of your stuff!! Paul Thanks for the info. My '71 has the early lens which looks to be a bit deeper. After doing some initial measurements on my early lens, I didn't think I'd need a spacer as needed with the later lens. Either way shouldn't be an issue. |
