2. Description of the Related Art A conventional technique will be described with reference to FIG. FIG. 3 is a cross-sectional view of the illumination direction variable illumination device.

Conventionally, this type of illumination direction variable type luminaire has a light-transmitting opening 1a on one side and a luminous axis of the light source 2 on the other side 1b of the luminaire main body 1 installed on the mounting surface T. A lamp body 4 having a reflecting mirror 3 covering the periphery is provided so as to be swingable.

[0004] A support spring 5 having elasticity protruding to the outer surface near the lower end of the side wall 1c of the instrument body 1 is provided.
Thereby, the instrument main body 1 is attached to the embedding hole U, and is formed so as to be rotatable in a horizontal plane direction about an axis perpendicular to the light transmitting opening 1a.

Therefore, the irradiation direction can be changed to a desired direction by changing the swing angle of the lamp unit 4.

[0006]

However, in the illumination direction variable type lighting apparatus shown in FIG. 3 as described above,
