Abstract: A self-generated lighting device, including: a frame, light source, solar cell, display panel, light guide plate, light reflecting plate, power control unit, and power storage device, wherein the power control unit controls electric power supplied to the light source and includes at least commercial electric power. The power storage device includes a power storage battery that stores electricity from the control unit, and supplies the electric power stored to the light source. The light source emits light energy toward a confronting side from one end side of an installation area in a frame, and the light guide plate guides the light energy emitted toward the display panel, and the light reflecting plate reflects the light energy toward the display panel, the light energy being guided toward a bottom surface portion of the light guide plate. The solar cell absorbs light energy of both direct and reflected light to generate electricity.

Abstract: A self-generated lighting fixture, including: a light source for illumination that emits light upon receiving supply of electric power; a transparent solar cell that absorbs light energy to generate electricity; and a power control unit that controls the electric power supplied to the light source and includes commercial electric power as one of electric powers to be controlled, wherein the light source has a first light source and a second light source provided independently of each other, the transparent solar cell absorbs a summed light energy from both the first light source and the second light source to generate electricity, and the power control unit supplies the commercial electric power to the first light source and supplies the electric power generated by the transparent solar cell to the second light source.

Abstract: Disclosed is a heat-resistant light-emitting device wherein luminance is increased by increasing the light emission area. A light-emitting device 1 comprises: a plate-like heat dissipation member 2; a light-emitting body 3 emitting linear or surface light, which is mounted on the heat dissipation member 2 and has a substrate 31 and a semiconductor laminate 32 formed on substrate 31; a fluorescent lens 4 covering the light-emitting body 3 on the heat dissipation member 2; and a light-emitting-body-side vacuum heat insulation layer 5 formed between fluorescent lens 4 and the light-emitting body 3. The light-emitting device 1 secures heat dissipation performance, while increasing the light emission area.
