who has 5mm Red,Green, Blue leds in 55 degrees and greater?

[**DONOTDELETE**]

anyone know where i can purchase, 5mm LEDS (red, Green and Blue) with a viewing angle range anywhere from 55 to 75 degrees? also i need the brightest(candela) in these specs.
i have tried the nichia Green and Blue in 45 degrees viewing angle. they look very good, but they don't "spread" quite enough for my needs.i have yet to find a Red led with a viewing angle greater than 30 degrees!

If you are not constrained to use 5mm LEDs, then I highly recommend the Lumileds SuperFlux series. See http://www.lumileds.com/products/list/super_flux_index.html

These LEDs are square, 7.5mm on a side, with 4 pins rather than 2. Electrically they are conventional 2 terminal devices, but they have the 4 pins for heat sinking. They tend to be among the most efficient LEDs available, and additionally can take 50-75mA depending upon color. The net result is that they are _very_ bright. If you get the broadest angle variety, the LEDs will be very bright over the entire hemisphere.

Lumileds is the same company that makes the Luxeon light sources.

If you must use the 5mm package, then another suggestion would be to buy a regular 30-45 degree LED, and then grind the plastic case down. This will change the beam angle, tending to make it much broader.

Lee, you can always grind the dome off of a 5mm, and then polish it smooth with toothpaste. The result will be a wide-angle LED. Grind it almost all the way down to the die for the widest angle.

A Q-tip with toothpaste on it chucked in a variable speed drill works well for the polishing step.

no one has any suggestions??

i will be producing thousands of these units, it would be very inefficient to "grind" the casing of each LED. i know some company out there has to make at least 5mm RED Leds with a viewing angle of 45 degrees or greater.

Nichia offers some beautiful wide-angle, colored and white 3mm LEDs that have the smoothest pattern I've ever seen. The white is the 312, but I'd have to do a bit of research to come up with the numbers for the other colors. Wanyne Y and Don M would probably know the numbers off the tops of their pointy little heads.

The up-pointing blue in this shot is one of them (oh, but it was a 5mm in the close-up shot of the bulb - in the shot where the sconce is lit, it is a 3mm blue with 70 degrees):

<font size="2" face="Verdana, Arial">Future-Active is the distributor, their minimum quantity is 60. You need to use part numbers to find anything on their site; keyword searches seem not to work.

Vishay Tefunken sells the 'Telux' LED, which uses the same package, but (at least by the datasheets) is much less efficient. Newark electronics sells these LEDs in quantity 1.

I am selling PCBs for bike lights which are populated with these LEDs, including a 'rainbow' if you want to see all of the colors in action. See Boost Converter Rainbow Array
