  However, since it was designed to irradiate only the front side of the doors and windows of the building, the movable range of the illuminator was narrow and it was difficult to flexibly use it according to the surrounding environment of the building.

  For example, it is difficult to illuminate two roads along corners such as the outer wall of a building with one lighting device. To illuminate two roads around the corners, two lighting devices are used. It is necessary to install or install a lighting device orthogonal to the center line of the inner corner of the corner. However, in the former case, the burden on the user is large, and in the latter case, the corner portion There is a problem that the lighting device cannot be stably installed unless a special dedicated fixture having a notched portion with a right isosceles triangle shape that fits into the lamp is used.

  Also, in order to further improve crime prevention performance by illuminating people approaching the building doors and windows from a relatively distant position, not only the front side of the building doors and windows, but also roads along the outer walls etc. In order to irradiate the light toward the left and right sides, it is necessary to install two lighting devices, and there is a problem that an economic burden on the user increases.

  Furthermore, the illumination device is basically designed as an illumination device installed outdoors, and when used indoors, it cannot irradiate light in the direction according to the user's preference, For example, it is difficult to irradiate light on the ceiling or wall and use it as indirect illumination.

In addition, when used for indoor use, not only direct illumination but also indirect illumination is possible, so that indoor illumination can be switched according to the user's preference.

  The lighting device 1 described above is a three-lamp type lighting device including left and right side illuminators 6 and a central front illuminator 5. However, like the illuminating device 1A shown in FIG. Instead of the partial illuminator 5, the front lid 60 may be fixed to the front surface of the main body case 2, and the front illuminator 5 may be omitted to constitute a two-lamp illumination device. Further, as in the lighting device 1B shown in FIG. 19, the left and right side illuminators 6 are omitted, and the opening of the main body case 2 formed at the attachment position of the side illuminators 6 is closed by the side lid 61. A one-lamp type lighting device can also be configured. As described above, since most of the three types of lighting devices 1, 1A, and 1B of the three-lamp type, the two-lamp type, and the one-lamp type can be configured by common parts, the type of the lighting device can be reduced while reducing the manufacturing cost. Can be easily increased.
