Abstract:
The present invention discloses a projecting apparatus. The apparatus includes light emitting diodes, a light guide plate and a projecting component. The light guide plate is mounted between the light emitting diodes and the projecting component. A switching control valve is mounted between the light guide plate and the projecting component. The switching control valve is switched between an on position and an off position between the light guide plate and the projecting component. In the on position, the switching control valve guides lights of the light guide plate to the projecting component as a light source of the projecting component; in the off position, the switching control valve cuts off the lights guided from the light guide plate to the projecting component to further cut off the light source of the light guide plate. The present invention further discloses a projecting equipment.
