A fluorescent lamp reflection housing is provided to adjust indoor illuminance by adjusting brightness of the light which is irradiated indoors without turning on/off a fluorescent lamp. A planar reflection plate is received in a reception groove of a case(10), which is buried in a ceiling. Holders for holding a fluorescent lamp are formed at both ends in a length direction of the case. A block plate(20) is rotatably installed on the case at a lower portion of the fluorescent lamp. A warm wheel is attached to one side of the block plate. A driving shaft(30) includes a warm which is geared with the warm wheel for rotating the block plate. The driving shaft is rotatably installed on the case to be vertical to the block plate. An operation wheel is coupled with one side of the driving shaft. A driving wire(40) rotates the operation wheel, so that the driving shaft is rotated, when the driving wire is contacted with an external surface of the operation wheel. |
