FIELD: image projectors.
SUBSTANCE: projector contains light-emitting diode as light source. Projector contains optical mechanism, using light-emitting diode as light source, electronic board module, heat-draining module and bearing frame. Module of electronic board contains first electronic board, second electronic board, interface of input/output for connection of external device, device for reading cards for connection of external memory card and control block. First and second electronic boards are positioned in parallel and with mutual overlapping, to decrease the occupied space. Heat-draining module contains ventilator, input air duct and output air duct, which form a heat-draining channel from input air duct through ventilator to output air duct. Light-emitting diode and control block are positioned in heat-draining channel to increase heat-draining effect.
EFFECT: reduced size of image projector without loss of efficiency and functional capabilities.
