BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device such as a road light for lighting a road.

[0002]

2. Description of the Related Art In a conventional lighting device, light distribution is set by giving a predetermined inclination to a lamp corresponding to a difference in road width due to the number of lanes or the like. FIG. 4 is a schematic external view showing a conventional lighting device. In FIG. 4, 41a, 41b, 4
6 is a pole, 42a and 42b are arms, 43 is a lamp, 4
4 is a two-lane road and 45 is a three-lane road.

The lighting device shown in FIGS. 4 (a) and 4 (b) is a road light in which a lamp 43 is provided at the tip of the poles 41a, 41b. The ends of the poles 41a and 41b are bent at predetermined angles α and β with respect to the horizontal line, so that the light distribution of the lamp 43 can be dealt with in accordance with the difference in the widths of the roads 44 and 45 due to two lanes and three lanes. 40a and 40b are set. The angle α is smaller than the angle β.

The illumination device shown in FIGS. 4 (c) and 4 (d) is a road light in which arms 42a and 42b to which a lamp 43 is attached are connected to a pole 46. Arms 42a, 42b
Ends of the road are bent at predetermined angles α and β with respect to the horizon, which allows the road 4 with two lanes and three lanes to be formed.
The light distribution 40a of the lamp 43 corresponding to the difference in the widths of 4, 45,
40b is set. The angle α is smaller than the angle β.

As described above, the poles 41a and 41b or the arms 42a and 42b, which are the supporting columns to which the lamp 43 is attached, are provided.
Is bent at a predetermined angle α, β to give a predetermined inclination to the lamp 43, so that the light distribution 40 corresponding to the width of the roads 44, 45 can be obtained.
a and 40b are set.

[0006]

However, in such a conventional lighting device, in order to set the light distributions 40a and 40b of the lamp 43 in accordance with the widths of the roads 44 and 45,
There was a problem that a column with its ends bent at different angles α and β was required. In view of the above problems, an object of the present invention is to provide an illuminating device capable of easily changing the light distribution of a lamp without changing the support.
