A Test Corner Lamp Design for a friend
This is a prototype corner lamp I'm creating for a friend, I'm testing the cooling ability of the design. This light was originally going to be a 5 chip design, but the bottom LED didn't work because the driver was NFG, so I just removed it from the array. I put strips of electrical tape across the back side of the tube and used a dab of clear silicone caulking to mount the drivers.
The lamp is composed of 4 x 8:1 (red:blue) 10W LEDs with matching drivers that I bought on ebay and the blower fan was purchased there too. I'm using a 20" long piece of rectangular aluminum tubing cut from a longer piece that I acquired at the local scrap yard, I think it was once part of a patio door frame, it's about 2" x 1" and has approximately 1/16" thick walls. Around 20 cuft/min of air blows through the tubing from bottom to top and I must say it runs surprisingly cool and quiet. I screwed "L" brackets on the back of the tube and onto a piece of wood strapping, screwed the strapping on the wall then mounted the light on the brackets with screws. This was built from some parts I had laying around and is a test rig, but the final design will look a lot like this and perform about the same. I'm going to build 4 of these with 5 chips and my friend is going to use them in the corners of this grow. I'm impressed by their ability to deliver intense light to almost every inter-node along the length of the plant and think I might build 4 corner lights for myself. Also, you could probably attach the blower to the tube with duct tape if you wanted to go the easy way.
Now for some pictures and in the next post a bit about the electrical end of things, what I'm using in this light and what my friend wanted for his lamps and how I would design my own corner lights. In short, I'll be discussing what would be the most economical and electrically efficient design for a lamp like this.
KEY INFO: You can use aluminum tubing like that found on patio doors to mount 10W led arrays. Just attach a 12 volt blower to one end and blow air through the tube.
