FIELD: lighting engineering.
SUBSTANCE: invention relates to lighting engineering. Illumination device includes a base made with possibility of insertion into the lamp or lighting fixture socket. Lighting device includes one or more light sources for emitting light in at least a first direction and one or more reflecting elements configured to define the boundaries of the opening, through which first spatial part of emitted light propagates in first direction; preventing propagation of the second spatial part of emitted light in a first direction; reflecting at least part of second spatial part of light in second direction, which differs from first direction, stencil mounted on said one or more reflecting elements, to allow passage of a third spatial portion of the emitted light through said one or more reflecting elements. Said one or more reflecting elements comprise a plurality of diaphragm shutter lobes made to slide on top of each other to vary the diameter of the bore.
EFFECT: technical result is possibility of light emission in several different directions.
