FIELD: optics.
SUBSTANCE: semiconductor light-emitting device comprises a white optically transparent body coated with a phosphor on the walls. Inside the housing is a laser diode having an axis of symmetry. Wherein the laser diodes are arranged in series on the axis of symmetry of the light emitting devices so that their axes of symmetry coincide. Ends of laser diodes are connected so that they are in electrical and mechanical contact and form an array of laser diodes, the radiation pattern of which has an axis of symmetry coincident with the axis of symmetry of the light emitting device.
EFFECT: technical result is to provide a semiconductor white light emitting device of high intensity light without increasing the size of light-emitting elements, thus providing uniform illumination of the phosphor.
