Hello everybody. A 100-watt lamp for growing tomatoes and cucumbers is now not even versed in radio engineering. This lamp is assembled from a needle radiator and two LED matrices of 50 watts each. Since these matrices have a built-in 220 V power supply, they are simply plugged into an outlet. Matrices I acquired a full plant spectrum.
For two matrices, I took a radiator 25 cm by 21, it is ready from the amplifier, which lay idle.
The dies are attached to 4 screws and the dies need to be positioned so that the through holes do not hit the needles or ribs on the other side. Mark holes, drill 0.5 mm smaller than the screw and drill. Put thermal paste so much that when screwing the matrix, it crawls out a little.
Next, solder the power wires to the matrix and connect it to the power cord in parallel.
We plug into the network and after about two hours we measure the temperature - in my case it was 65 degrees and did not increase anymore.
Of course, for better cooling in a room with a high ambient temperature, you need to install a cooler on top for forced cooling, but if you set a timer and turn off the lamp every 15 hours, then the cooler is not needed.
All a good harvest. Any salad under this lamp will grow perfectly all winter without sunlight.
