Patent Document 2 discloses a structure in which a luminaire is fixed and installed on a wall surface with a screw through a hole provided in a piece extending to a side end of a housing.

Japanese Patent Laying-Open No. 2006-066213 (FIGS. 3 and 7) Japanese Patent Laying-Open No. 2007-087920 (FIG. 2)

  In recent years, lighting has been increasingly used as decorative lighting so that it is not directly illuminated not only indoors but also outdoors, and indirectly produced by directing illumination. In such a case, there are various methods of illuminating as indirect illumination, and the direction and angle of illumination may be specified in detail. In addition, since the direction of illumination is fixed, it has been desired to provide light efficiently after condensing as much as possible.

Therefore, in these conventional structures, since the lighting fixture is directly fixed to the wall surface, it is impossible to illuminate by changing the direction, and if the direction of irradiation is changed later, the angle is changed. There is also a problem that the work of making the spacers and the like according to the angle becomes complicated.
Further, since the conventional lighting fixture is heavy, it is difficult to make the angle adjustment mechanism compact. In particular, when installed on a wall surface, its own weight is applied to the angle adjusting mechanism, and it is difficult to make it compact.

  Then, an object of this invention is to provide the lighting fixture provided with the angle adjustment mechanism which can change an angle easily and was comprised compactly.

The base (13, 63) that is connected to the base (13, 63) via the support shaft (14, 64), and the pedestal (21, 61) that holds the housing (30) is angled. A fitting hole (20/70) formed by a plurality of holes that can be selected as a plurality, a fitting means (19/67) for fitting into the fitting hole (20/70), and the fitting Biasing means for biasing the fitting means (19, 67) in the direction of fitting the holes (20, 70). 6 and 66) and an operation portion (12 and 62) for releasing the fitting of the fitting means (19 and 67) against the urging of the urging means (16 and 66). By operating the operating portion (12, 62) to release the fitting between the fitting means (19, 67) and the fitting hole (20, 70), the restriction of the rotational movement is released, and the support An angle adjusting mechanism (10/60) for rotating the cradle (21/61) about the shaft (14/64) is provided.

  With the above configuration, since the restriction of the rotational movement is released by a simple operation of pulling or pushing the operation unit, the angle can be easily changed and a compact configuration can be achieved.

  The lighting apparatus (1) according to claim 2, wherein the fitting hole (70) includes a groove-like groove communicating with a part of the hole, and a protruding means protruding in the direction of the groove between the holes. (76), and the fitting means (67) is provided with a concave portion (72) which is concavely cut out larger than the size of the projection means, and the operation portion (62) is operated so that the concave portion (72) When crossing the position of the protrusion means (76), the fitting means (67) and the fitting hole (70) are released from the fitting, and an angle adjusting mechanism (rotating and moving the cradle (62)). 60).

  With the above configuration, the restriction of rotational movement is released by a simple operation by simply pressing the operation unit, so the angle can be easily changed, and the structure can be firmly fitted, making it difficult to come off and compact. Can also

It is fixed so that it cannot be done.

A second embodiment of the present invention will be described below with reference to FIGS.
FIG. 6 is a diagram illustrating a state in which the adjustment mechanism is fixed to the fixed angle 60 of the luminaire 1 according to the second embodiment, and FIG. 7 is a diagram illustrating the state where the adjustment mechanism is released from the fixed angle 60 of the luminaire 1 according to the second embodiment. FIG. 8A is a cross-sectional view of a fixed angle representing a state in which the fixed angle 60 of the lighting fixture 1 in the second embodiment is fixed, and FIG. FIG. 9 is a sectional view of a fixed angle showing a state in which the fixed angle 60 of the luminaire 1 according to the second embodiment is released, and FIG. 9 is a front view of the fixed angle 60 when the luminaire 1 according to the second embodiment is viewed from the side. It is the figure seen from.

  The fixed angle 60 includes a U-shaped pedestal 71 that opens upward to receive the housing 30 of the luminaire 1, and a base 63 that is fixed to a wall surface, a ground surface, or the like with a bolt. ing. The cradle 71 and the base 63 are connected by a support shaft 64 made of bolts, and the cradle 71 can rotate around the support shaft.

  As shown in FIG. 6, the cradle 71 has an upper portion formed in a U shape, and an angle adjusting piece 61 is provided at one end of the lower end of the U shape. As shown in FIG. 8, the angle adjusting piece 61 is provided with a hole, and a cylindrical body 67, which is a part of the operation unit 62, is inserted through the hole to the fitting hole 70 of the base 65. Has been.

  The operation part 62 is provided with a retaining piece 24 constituted by an E ring at one end of a cylindrical body 67, and the retaining piece 24 is formed in a hole provided in the fitting hole 70 of the base 63 or larger. So that they do not come out of these holes. Also, a piece larger than the diameter of the spring 66 inserted between the hole of the bearing 73 and the bearing protrudes at the other end so that the spring 66 does not come out.
