SIGNALING LIGHTING UNIT Russian patent published in 2006 - IPC F21S2/00 

FIELD: signaling devices, mainly beacon apparatuses and railway traffic lights.

SUBSTANCE: the device has a radiation source isolated from exposure to environment by a transparent shell connected to the body, as well as contacts and a pin with semiconductor crystals positioned on it, which serve as a radiation source. The transparent shell has a cover from above, and the body has openings for input of flexible conductors to the contacts. The pin is made in the form of a printed-circuit board, and the semiconductor crystals are grouped together in light-emitting diode modules located at nine levels. At the first and ninth levels positioned are three light-emitting diode modules at each, at the second level-six light-emitting diode modules, at the third, fourth and sixth levels-eight-emitting diode modules at each, at the fifth level-nine light-emitting diode modules, at the seventh level-seven light-emitting diode modules, at the eight level-six light-emitting diode modules. The modules are installed at proper distances from the transparent shell and at angles to the optical axis providing for production of crossing light flows formed in the preset directions. The transparent shell is made in the form of an arc providing for light transmission within the frequency range 460 to 633 lm.

EFFECT: enhanced intensity of radiation and expanded field of application of the signaling lighting unit.
