PROBLEM TO BE SOLVED: To extend the range of installation space, eliminate restrictions due to use of a power supply for longer service life, and make a face illumination fixture thinly shaped by providing a solar battery, a control circuit for electric control due to the solar battery and an accumulator storage part, and a double- sided illumination plate. SOLUTION: In an illumination fixture composed of a solar battery 1, a double-sided illumination plate 2, a control circuit, a battery storage part 3, etc., electric power generated by means of the battery 1 is charged by means of an accumulator via a cable built in the transverse part of the plate 2. When the periphery is dark, the plate 2 is light-emitted by actuation of an optical sensor 6 and on-operation of an manual switch 9. When the periphery is bright, the plate 2 is out by actuation of the sensor 6 or off-operation of the switch 9. Then, the battery 1 starts charging, and charging with the accumulator is performed. Thereafter, the similar double-sided illumination is performed according to the peripheral brightness. Since the constitution of the illumination fixture is advanced in combination with the existing technology, the fixture can be easily manufactured, its high quality and low price is accomplished, its application field is widened, and longer service life, etc., is ensured. |
