UNIVERSAL SOURCE OF POLYCHROMATIC OPTICAL RADIATION Russian patent published in 2006 - IPC F21S2/00 F21Y101/02 

FIELD: optics.

SUBSTANCE: universal source comprises housing, power supply unit, set of light-emitting units provided with a devices for current control, optical elements, and means for positioning. The means for positioning has three degrees of freedom and provide the light-emitting units to be positioned with respect to the diffraction unit according to the formula d(sinα_i + sinβ _i) = λ_i, where d is the pitch of the diffraction unit, α_i is the angle of incidence of the beam, which is the angle between the normal to the diffraction unit and direction of the beam from i-th light emitting unit, β_i is the diffraction angle, m is an integer, and λ_i is the wavelength of the beam from i-th light-emitting element.

EFFECT: expanded functional capabilities.
