PURPOSE:To obtain a lighting equipment by allowing a lamp to be located to a reflection shade for variable distribution and also to be arbitrarily located to the reflection shade. CONSTITUTION:A setscrew 29 is loosened and moved up and down along both slits 14 in a mainframe 11 to move up and down a lamp 32 together with a socket board 26 and a lamp socket 31 against the mainframe 11. Next, the screw 29 is fastened to fix the socket board 26 to the mainframe 11 and fix the lamp socket 31 and the lamp 32 to the mainframe 11. In this way, the location of the lamp 32 can be arbitrarily and continuously adjusted to a reflection shade 21 along its center axis. As the lamp 32 is located higher against the reflection shade 21, an illumination angle from the reflection shade 21 is greater. A scale 17 is provided on the mainframe 11 along the slits 14, therefore to ensure easy height adjustment of the lamp 32 with the head of the setscrew 29 matched to the scale 17. |
