FIELD: light sources using light-emitting diodes for local illumination of working surfaces.
SUBSTANCE: proposed light source is made in the form of monolithic hybrid integrated circuit placed in package of standard lamp base and optically transparent light guide accommodating chips of emitting p-n junctions disposed on heat-transfer base; each chip is joined with cylindrical projection of light guide having conical depression on butt-end.
EFFECT: provision for desired light distribution for uniform local illumination of working surfaces.
