Here, in one embodiment of the present invention, in order to reduce the weight of the member, the lengths of the second side surface 52a2 and the first side surface 52b1 in the longitudinal direction of the lighting device 1 are predetermined lengths, and the support member 5 is viewed from the side. However, the lengths of the second side surface 52a2 and the first side surface 52b1 in the longitudinal direction can be arbitrarily set. For example, the support member 5 may be overlapped in a side view.

図3および図4に示すように、裏面50aの一端において、第1挟持部52aと第2挟持部52bとは、互いに対向しない位置に形成される。そのため、第1挟持部52aの第2側面52a2に接した電源コードは、第2挟持部52bの第1側面52b1に接する。このように、電源コードは、第1挟持部52aの第2側面52a2と、第2挟持部52bの第1側面52b1とに接することにより、略湾曲する。その結果、電源コードは、第1挟持部52aと第2挟持部52bとで挟持される。   As shown in FIGS. 3 and 4, at one end of the back surface 50a, the first holding part 52a and the second holding part 52b are formed at positions that do not face each other. Therefore, the power cord in contact with the second side surface 52a2 of the first clamping unit 52a contacts the first side surface 52b1 of the second clamping unit 52b. In this way, the power cord is substantially curved by contacting the second side surface 52a2 of the first clamping unit 52a and the first side surface 52b1 of the second clamping unit 52b. As a result, the power cord is clamped between the first clamping unit 52a and the second clamping unit 52b.

また、図3に示すように、第2挟持部52bの第1側面52b1には、凸部52cが形成されている。電源コードは、凸部52cによって、裏面50aの垂直方向に係止される。   Moreover, as shown in FIG. 3, the convex part 52c is formed in the 1st side surface 52b1 of the 2nd clamping part 52b.

また、図3に示すように、支持部材5は、照明装置1の長手方向に伸びる延伸部53を含む。延伸部53は、載置面50の裏面50aの一辺から所定の距離だけ内側に形成される。そのため、延伸部53の側面53aと、第1挟持部52aの第2側面52a2との間には、空間が形成され、該空間に電源コードを配置可能である。   Further, as shown in FIG. 3, the support member 5 includes an extending portion 53 that extends in the longitudinal direction of the lighting device 1. The extending portion 53 is formed on the inner side by a predetermined distance from one side of the back surface 50a of the placement surface 50. Therefore, a space is formed between the side surface 53a of the extending portion 53 and the second side surface 52a2 of the first holding portion 52a, and the power cord can be disposed in the space.

なお、電源コードが配置される空間は、延伸部53の側面53aと、第1挟持部52aの第2側面52a2とをそれぞれ照明装置1の長手方向に延長した場合に、該第2側面52a2と、該第1側面52b1と、載置面50の裏面50aと、ヒートシンク8とで囲まれる空間である。本発明の一実施形態においては、部材の軽量化のため、側面53aおよび第2側面52a2の長手方向の長さは、所定の長さとされる。   The space in which the power cord is arranged is the same as that of the second side surface 52a2 when the side surface 53a of the extending portion 53 and the second side surface 52a2 of the first holding portion 52a are extended in the longitudinal direction of the lighting device 1, respectively. A space surrounded by the first side surface 52 b 1, the back surface 50 a of the mounting surface 50, and the heat sink 8. In one embodiment of the present invention, the length in the longitudinal direction of the side surface 53a and the second side surface 52a2 is set to a predetermined length in order to reduce the weight of the member.
