<P>PROBLEM TO BE SOLVED: To provide a light fixture capable of using even at the time of power failure or power supply cut-off by a power-saving light source and a charged battery, while suppressing internal heat in the lighting box. <P>SOLUTION: An LED, an RGB composition LED, an EL tube, and a cold cathode tube or the like of power-saving, low heat-generating, and light-weight are used to alleviate constraint. Lighting is made by rectifying the commercial power supply and driving it. Furthermore, the lighting box is charged automatically immediately upon flowing current, and at the time of power failure or the like, it is lighted instantaneously by the charged battery, therefore it can be used widely as a multifunctional light fixture. <P>COPYRIGHT: (C)2007,JPO&INPIT |
