Hello everybody. Of the radiators from powerful transistors, I built a good 36-watt LED lamp with a full plant spectrum. This lamp can be suspended and put on the windowsill. The size of the radiators is 8 cm by 5 cm and the whole structure is 16 cm by 10 cm.
The LEDs of 3 watts of the full plant spectrum were soldered to this 32 mm socket; it corresponds in size to the diameter of the transistor.
Radiators 4 pieces they are twisted together for rigidity. The bonding area must be wiped with alcohol. Glue already soldered pads with LEDs on hot-melt adhesive.
To increase the area of the radiators, I made the walls of the case made of stainless steel.
That's how it shines.
The design is very simple and reliable. It may fall from the windowsill to the floor and not break. Made for lemons since there are more of them this year.
Thank you all for watching.
