Abstract: A storage device includes a storage body having an opening and a lid for selectively opening and closing the opening of the storage body. The storage body has a light emitter and a power receiving portion connected to the light emitter. The lid has a power supplying portion, which is configured to supply power to the power receiving portion by the direct current resonance method. The light emitter emits light to interior of the storage body at a first luminance when the opening is closed by the lid. When the lid opens the opening so that the distance between the power receiving portion and the power supplying portion is reduced, the light emitter changes the luminance to a second luminance, which is different from the first luminance.

Abstract: An LED illumination device 1 for vehicle use includes an LED lamp 10, a circuit 5 for supplying a current to the LED lamp from a power supply mounted on the vehicle, and a current control unit 7 for controlling the current supplied to the LED lamp 10 so as to be inversely proportional to the environmental temperature of the LED lamp 10. In this manner, in the current supply circuit, an LED chip 11 is coupled to the collector of a common-emitter type transistor 15. The current control unit includes a PTC thermistor 21 and the PTC thermistor 21 is coupled to the base of the transistor 15, whereby a current supplied to the base is made small when the temperature of the PTC thermistor 21 becomes high. The PTC thermistor 21 is placed in a circumstance where the temperature thereof becomes same as the environmental temperature of the LED chip 11 at the time where the LED chip 11 is in an OFF state.
