Hello everybody. Parsing electronics I’ve found such a needle radiator for 60 years. Its dimensions are 10 cm by 19 cm.
The full-spectrum matrix was glued to 20 watts by 220 V.
First you need to solder the wires to the matrix, glue this field on the radiator, otherwise all the heat goes into the radiator.
Legs made of 5 mm studs.
As this lamp did for a living room, it was necessary to install a frosted plexiglass screen.
The result was an original design for the windowsill and harmless for the eyes.
Thank you all for your attention.
