<P>PROBLEM TO BE SOLVED: To provide an lighting system capable of emitting light in wide-angle, middle-angle and narrow-angle patterns without using two or more reflection panels. <P>SOLUTION: A lamp 8 with a transparent outer bulb 9 is disposed within a reflection shade 6 of the lighting system. The lamp 8 is structured to be movable to positions Pw, Pm and Pn that correspond to the wide-angle, middle-angle and narrow-angle patterns, respectively, within the reflection shade 6. A reflection surface 20 of the reflection shade 6 is shaped such that light can be emitted in the wide-angle, middle-angle and narrow-angle patterns corresponding to the positions Pw, Pm and Pn, respectively, of the lamp 8. <P>COPYRIGHT: (C)2010,JPO&INPIT |
