As a result, there is no need to provide a separate spring mounting bracket, and there is no need for a fastener such as a screw for fixing the separate spring mounting bracket.

<Effects of Modification of Embodiment 2>
As described above, according to the lighting device 1 according to the modification of the second embodiment, there is no need to use supplementary materials such as spring receiving metal fittings and fixing screws for fixing them as in the conventional coupling device. It can be eliminated, and the material cost and processing cost can be reduced. Moreover, since the spring mounting portion 36k is integrally formed with the power supply device 33k mounted on the base main portion 300k of the lamp 3, deterioration of secondary materials or incomplete fixation of the lighting device 1 due to long-term use of the lighting device 1 is prevented. The lamp 3 can be prevented from falling without being affected by the

In the above-described second embodiment and its modification, the spring 26 as the instrument-side connecting portion of the connecting device 4 may be made of a plate-shaped elastic material, or may be made of a wire elastic material that is bent. It may be formed by

In addition, in all the embodiments including the modified examples described above, the lamp-side connecting portion of the connecting device may be made of an elastic material, and the fixture-side connecting portion may be made of a spring mounting portion that engages with the elastic material. good. In this case, the spring mounting portion, which is the fixture-side connecting portion, may also function as a connecting portion by processing the main body portion 20 of the lamp mounting fixture 2 itself.

In addition, in all the embodiments including the modified examples described above, ribs may be provided at the bent portions of the spring mounting portions for the purpose of stabilizing the bending angle of the spring mounting portions or reinforcing the bent portions.
