<P>PROBLEM TO BE SOLVED: To provide a lighting device capable of attaining suitable appearance by reducing luminance unevenness of a light-emitting surface caused by light emitted from a light source of a night light when lighting up the night light. <P>SOLUTION: The lighting device includes a device body having a space S at a central section, primary light source LEDs 4, a first light-emitting surface 2a arranged at an outer periphery of the device body and emitting light by emitting the light from the primary light source LEDs 4, night light LEDs 5, for emitting light from an outer periphery of the space S to a center direction, a second light-emitting surface 3a arranged by being opposite to the space S and emitting light by reflecting light emitted from the night light LEDs 5, and an inner surface 1a having the space S disposed between the second light-emitting surface 3a and the inner surface 1a and emitting light at a second light-emitting surface 3a side by reflecting the light emitted from the night light LEDs 5. A second light-emitting surface 3a resulted from the night light LEDs 5 can be formed on the narrow central section in comparison with the whole surface of the device body at an irradiating surface side, and consequently, the uniform light-emitting surface of the lighting device can be obtained when lighting up the night light. <P>COPYRIGHT: (C)2013,JPO&INPIT |
