Hi all, first post here. Trying to build some rgb lighting fixtures for use at gigs.
Looking for any help and advice about products to use mainly the digital rgb led strip.
Basically it is an upright standing frosted perspex tube that will have digital rgb led strip glued at the back on the inside. I have attached a drawing to give a representation, these need to be super bright as they may be used in daylight occasionally, there will be 2 strips together at the back to add to the brightness. As the tubes are 1.7m tall then the 2 strip adds to 3.4m.
So really, if anyone has suggestions or recommendations for rgb digital strip it would help me out, searching this on the internet is a total minefield of information.
My requirements are that it -
1. Needs to be digital strip so that i can do things like chases
OK. You probably need individually addressable LEDs.
2. Would be great if it could mimic a strobe effect i.e fast response.
3. It is super bright as they may sometimes be used in daylight, minimum of 14w/m
4. Would prefer 60led/m if possible
About the only one I've seen that can do all that is this: http://www.ebay.com/itm/160896346789
I've got one and it's pretty damn bright. I haven't tried it in direct sunlight but I imagine it would be easily visible. Under fluorescent lights I don't put it above quarter power.
Things i've yet to get my head around are what the differences are between the chip types ie ws2801, ws2811, LPD8806/6803, TLS3001, TM1809/1803/1804/1812, HL1606,etc
Do they all do the same thing?
Pretty much. They have different data protocols, different number of control wires, but basically the same thing.
Also is the voltage important to brightness i.e 5v,12v and 24v strip?
The voltage has nothing to do with brightness. Usually it's to do with LED grouping, at 12V the LEDs will probably be in groups of three (i.e. they're not individually addressable...)
One thing to watch out for with 5V strips is they need a beefy power supply. A full 5M strip of LEDs would need 18 amps to drive it (900 LEDs at 20mA each).
Just a note which may alter things, i will be controlling these from a dmx lighting desk so i assume i will need to use a dmx to pwm decoder to control these!
Hope someone can point me in the right direction! Thanks
I wouldn't know about connecting it to a lighting desk but contact the seller, he's really helpful and knows his stuff.
