This is a small 3d printed led light i made for my vegetables houseplant.
This project is also hosted on hackaday and instructables is available
Designed to be as cheap as possible and let you grow your own food, but to give the maximum efficiency and don´t involve any soldering. It's perfect to raise not very light demanding plants or for early stages, i'm sure it also can be used for photography, hydroponics, aquaponics, any kind of indoor setup and anything else you got in mind!
This light consists of 4x bridgelux BXEB L0280 led bars which are driven by a Meanwell driver in parallel with two options:
APC 35 - 1050: driving each bar at 1.05A/4 = 262,25 mA.Gives us a total power at 20v of around 1.05*20 = 21W
LPC 60 - 1400: driving each bar at 1.4A/4 = 350 mA. Gives us a total power at 20v of around 1.4*20 = 28W
Compared to commercially available solutions, has a lumen output similar to a HLG 65 vegging board, efficiency close to DIY COB leds (Vero, CXB3590, Citizen... ) but with a higher coverage area. Nothing to do with other cheap solutions as 5050 led strips, chinese amazon lights or e27 bulbs.
Max drive current of the boards its 700mA so we are always under half of the current with any of the boards, so heatsink isn't mandatory. At the current used they have a 180 lm/w efficiency, not bad at all for they price.
APC variant has been tested for over two months already and hasn't show any problem, LPC variant has not been tested, because i don't have the driver, but i made the model also because i thought like its so if somebody build it any feedback would be very welcomed! 3d files available at thingiverse and myminifactory
Always wear sunglasses when looking at this leds! never put them in a place where you can have direct vision of them.
This lamp is working for me, but I am not in any way electrician and i can't assure this is complient with all security directives, always double check all connections, think on your own if everything is safe. Design is not fully isolated so use in humid spaces it's not recommended, i am not responsible in any way of material or personal damages caused for misuse, bad mount, or anything else derived from this model.
Size of each piece is 7.2 mm to be printable in any printer and made to fit 200mmx200mm printers, probably could be printed thinner, for that just scale that axis.
All four sides are the same so you need to print:
-For apc driver:
4x side
1x apc
2x Wago_apc
-For LPC driver
4x Side
1x LPC
1x Wago_LPC
LPC version has not been tested so if somebody can test it and offered feedback i can modify the STL, also if somebody wants original files i can provide them.
