PURPOSE:To improve the reliability in the case where one annular fluorescent lamp is supported by two support members, and prevent the fall of the annular fluorescent lamp. CONSTITUTION:A central base part 435 of slave holders 431, 432 is installed inside of a supporting block so as to be oscillated freely in a certain range along the diameter direction of annular fluorescent lamps 201, 202 and so as not to be oscillated in the bulb axial direction of a bulb part 204 supported by the slave holders 431, 432. One socket block 300 is provided with plural main holders 340 corresponding to the number of the annular fluorescent lamps 201, 202, and a supporting block 400 is provided with plural slave holders 431, 432. Furthermore, the main holder 340 is connected to a socket 350 connected to the annular fluorescent lamps 201, 202, and the other end of a connecting wire 357 extended from the socket 350 is connected to a luminaire main body 100. |
