Hi EricB,
I'm in the process for starting a new business specialising in RGB lighting, mostly accent or mood lighting.
Just saw your post after finishing the PCB for what you want, thought I'd answer and give myself a bit of a plug at the same time.
It contains 10 100mA 5mm LEDs, 4 red, 3 blue, 3 green. Two PCBs, the LED module 50mm round, controller about 40mm diameter. Currently running at 12V (for fixed spot cans) as LEDs are in series, if it works I'll make another LED head in parrallel for battery (ie torch) operation. Email me if you want to get updates on the prototype progress. First things I have to test is the thermal issues.....these LEDs and dropping resistors do get warm.
Now for the plug....sorry to hijack your post there /ubbthreads/images/graemlins/smile.gif
I've got flouro replacements with 5 seperate banks of 6 RGB (2R, 2G, 2G) 100mA superfluxes (
www.powerleds.com) demonstrated at Brookvale Lighting here in Sydney, Australia (if there are any Northern Beaches types around pop in and say hello to David the store owner, my lights are the pretty things in the back). When I've got business registration all sorted out I'll put up a web site with photos and specs and start supplying to the public. Again depending on market price I'll supply kits or pre-made units. Probably for the torch I'll release the design public domain as a bit of a customer attention grabber (though I'll keep to flourofitting to myself...sorry guys it's my flagship product and I've spent ages doing the PWM control).
For now..some sanity check questions for the forum:
Market prices.....please specify currency....I'll need to convert to Australian dollars.
a) What sort of price would you pay for a model 2 board 400mmx100mm, 5 banks of RGB, 10x100mA superfluxes per bank (4R,3G,3G), 12V AC supply, serial or one button controll? I'm looking at around $AU150 at the moment....is this reasonable?
b) What sort of price would you find reasonable for the RGB spot (or 6V torch)...again in either kit or pre-made form? I haven't even costed this.....another reason to offer it public domain.
User interface:
c) For the torch I'm hoping to get by with a 8pin 12F675 PIC..which is a bit limiting on choices for control pins after the PWM channels are used. I'm hoping to prototype a control system with two potentiometers (or sliders). One to control colour moving through spectrum, one to control intensity. A switch provides a mode control for patterns.....as a potential RGB torch user would you be happy with this instead of seperate RGB sliders? Anyone done this before? Code examples anyone?
Research.
d) has anyone seen any good articles on RGB placement to ensure even mixing? My flouro replacement has less of a problem because it has wide angle LEDs, the spots are more critical....I can never quite get rid of the fringing.
Again, sorry to hijack the post, but.....I just finished designing what you want when I saw it!
I'll get back to the forum with announcements as progress is made.
