PURPOSE:To facilitate the control of the light distribution of a straight tube type luminaire and to improve the manufacturing processibility so as to reduce the manufacturing cost by composing the reflector of the lighting equipment separately of a central reflecting member and light distribution control side reflecting members arranged respectively on both sides of the central reflecting member. CONSTITUTION:In straight tube type luminaire provided with a straight tube type lamp and a reflector reflecting light emitted from the lamp, the reflector is composed separately of a central reflecting member 2c and side reflecting members 2a, 2b arranged respectively on both sides of the member 2c to control the light distribution of the lighting equipment. At the time, it is preferable that the reflecting surfaces of the side reflecting members 2a, 2b should be finished respectively in specular ones and the reflecting surface of the central reflecting member 2c in non-specular one or in white color when necessary. The members 2a, 2b, 2c are preferably interconnected mechanically via rivets 8 or the like by using one or two pairs of reinforcing member 7. At the time, it is preferable that a bent edge portion 70 overlapping the bent edge portion 10 of the side reflecting member 2b should be formed at one end of each of the reinforcing members 7 and a portion 71 engaging the central reflecting member 2c at the other end. |
