LIGHT PULSE LIGHTER (OPTIONS) AND METHODS OF LIGHT PULSE LIGHTING OF PLANTS Russian patent published in 2008 - IPC A01G9/26 

FIELD: lighting technology.

SUBSTANCE: light-emitting diodes (LED) with different radiation spectrum are used as light sources. Control unit input is connected to pulse frequency adjuster, dark pause adjuster and light pulse amplitude adjuster. Pulse shaper is represented as switch in LED circuit between common negative output and control unit. In second option of lighter design, light source housing is represented as strip along surface with plants and light sources having LED with different radiation spectrum separated along the strip. In third option of lighter design, surface with plants is represented with internal surface of cylindrical pipe. Housing with light sources is represented with several strips equally distanced from each other but with some space along forming surfaces. In fourth option of lighter design, surface with plants is represented with interior space of cylindrical pipe and pulse shaper is in the form of correct prism. Lighting method is a scanning of light flow from aligned LEDs with different radiation spectrum with sequential lighting of surface with plants.

EFFECT: possibility of light flow frequency, radiation spectrum, amplitude and beam form adjustment.
