Illuminating device
First Claim
1. An illuminating device comprising:
- a connecting portion configured to be supplied with power;
a case having a tubular shape;
a support body disposed inside the case and configured to divide the case in a radial direction;
a plurality of light emitting diodes disposed on a first surface of the support body;
a diffuser provided between and in contact with the support body and the plurality of light emitting diodes;
a secondary battery disposed on a second surface of the support body, wherein the second surface is different from the first surface on which the plurality of light emitting diodes are disposed;
a power supply circuitry configured to supply power to the plurality of light emitting diodes and charge the secondary battery,wherein the secondary battery supplies power to the plurality of light emitting diodes in a state in which the power supplied from the power supply circuitry is stopped; and
a timer circuit configured to determine whether or not a pre-determined time has elapsed in the state in which the power supplied from the power supply circuitry is stopped,wherein the secondary battery stops supplying the power to the plurality of light emitting diodes based on the determination that the pre-determined time has elapsed.

Abstract
An illuminating device includes a connecting portion supplied with power, a conversion circuit that converts power supplied from the connecting portion, a case having a tubular shape, a support body that divides the case in the radial direction, and a plurality of light emitting diodes provided on one surface of the support body. The illuminating device further includes a drive circuit that drives the light emitting diodes, a secondary battery provided on the other surface of the support body, a charge/discharge control circuit for the secondary battery, and a control section that lights the light emitting diodes by supplied power and charges the secondary battery. The control section permits lighting of the light emitting diodes by a discharge of the secondary battery in a state in which power supply is stopped.
