On the other hand, as described above, the connection member 40, 50 serves to electrically connect the PCB 4 and at the same time to secure the PCB 4 to the frame 10. However, since the PCB 4 is long in the longitudinal direction, a member for fixing the PCB 4 to the frame 10 is separately required in the remaining parts except where the PCB 4 is connected. In addition, as described above, since the upper part (open part) of the frame 10 faces the part to be illuminated, and the lower surface of the frame 10 is connected to a ceiling or a wall, the PCB 4 is separated from the frame 10. It is necessary to fix it.

Conventionally, a heat radiation adhesive or a heat radiation tape (3 in FIG. 1C) was used for the fixing. However, when the heat radiation adhesive and the heat radiation tape 3 are used, the adhesion force (adhesive force) of the heat radiation adhesive and the heat radiation tape 3 is lowered by the heat generated by the LED 1, so that the PCB 4 is separated from the frame 10. I prayed. LED lighting 100 (100a) according to the present invention is provided with a fixing member 30 for fixing the PCB (4) to the frame (10). As shown in FIGS. 2 to 4 and 10 to 12, the fixing member 30 includes a main body 31 and third fixing means 35 formed on the main body 31.
