Abstract
An LED light comprising a light-emitting device provided to power supply means, encapsulating means for encapsulating the light-emitting device with a light-transmitting material, a reflective surface for reflecting the light emitted from the light-emitting device to a direction perpendicular to the center axis of the light-emitting device or at a large angle to the center axis, opposed to the light-emitting surface of the light-emitting device, a light-emitting diode having a side directing surface for directing sideways the light reflected from the reflective surface to a direction perpendicular to the center axis of the light-emitting device or at a large angle to the center axis, and a reflecting mirror disposed around the light-emitting diode.
