Multicolored ethernet controlled LED lamp

led lamp

[Laurens Tromp] stumbled upon this LED lamp project while looking for a datasheet. The lamp has two heads with 252 LEDs each. The individual heads have equal number of red, blue, green, yellow and white LEDs. At the base of the lamp is a touch pad that has a virtual slider for each individual color’s intensity. The heads can be controlled separately or together. The lamp can also be operated over ethernet since its controller is a RabbitCore RCM2200. The only answer I can’t seem to find in the extensive documentation is how much this milled aluminum monstrosity weighs: 110 pounds.

  1. this is odd.

    off topic. my blacklight doesnt seem to detect ‘stains’ like they do on CSI, what am i doing wrong?

  2. “my blacklight doesnt seem to detect ‘stains’ like they do on CSI, what am i doing wrong?”

    You’re watching CSI and believing it’s real science, that’s what’s wrong. :)

    Umm.. cleaning your carpet? (sorry, I couldn’t resist) :p

    Seriously, you may not have a bona-fide “blacklight” , or the ‘stains’ you’re testing aren’t phosphorescent. Try testing it out in the bathroom – most soaps and detergents, among other things, show up *real* bright under UV.

  4. I have a high powered blacklight. ment for looking for scratches on contact lenses.

    and yah, mistery stains glow bright.

    even if somone had to fix the paint on a wall or
    remud dry wall, lots of unexpected stuff shows up.

  6. are you using the cool orange glasses like they use on CSI? cuz i think they are req. to see blood or bodily fluid.

  7. Pretty sure those are just to protect their eyes. I’ve had dental work done that required a strong UV light to harden whatever it is they used, and the operator wore the orange glasses.

  8. The orange plastic absorbs the UV light. That’s why most of the work done in Intel and AMD’s fabs is under orange light. Any stray UV would wreak havoc on the photosensitive resists used.

  9. I always figured the cop shows just sorta forgot about the part where they spritz the room with luminol to really make the stains glow bright…

  10. Holy crap! $3800 dollars for parts alone!
    He must have access to all the CNC equipment etc. since there’s no mention of any costs involved with that.

  11. only $3800 shipped not including the assembly of it, more like $3700 when you discount the stuff not used. I’ll take 3 :). Though why the yellow and white leds when just red green and blue should be all thats needed.

  12. rgb + yellow and white due to color blending problems at short distances. from far away, rgb blend nicely to create other colors. up-close, rgb need to be very tightly packed (e.g. in one led) to create yellow and white. moreover, leds do not focus on one spot for ideal color blending. thus for this led lamp, white and yellow were added separately. a more detailed discussion can be found on page 4, next to the first figure on the page.
