Patent attributes
The solution relates to lighting technology, namely to LED lamps powered directly from the AC mains. The technical result is to simplify the design, improve heat dissipation and reduce the labor intensity of manufacturing high-power lamps of general use, resistant to external influences>IP65, and with a minimum cost and labor intensity. In some cases, the LED lamp contains a radiator housing made in the form of a hollow cylindrical body made of an optically transparent material; a flexible aluminum printed circuit board, on a mounting surface of which LEDs and a driver are mounted; end caps, at least one of which is provided with means for connecting to a power supply network, while the flexible printed circuit board is configured in the form of a roll, the mounting surface is disposed outward, and part of the board with the driver is bent inside the roll, while the light-emitting surface of the LEDs is immersed in a transparent material housing, and the mounting surface of the configured printed circuit board has direct thermal contact with the transparent material.
