Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in the angle setting mechanism of a lighting fixture supported on the inner wall of a tunnel of a motorway.
[0002]
[Prior art]
Traditionally, lighting fixtures used in baseball fields, indoor arenas, auto racing fields, etc. are illuminated with a predetermined brightness value, so it is important for players to play safely without feeling glare, Conventionally, for example, a sighting device with a laser is detachably attached to the front end portion of the luminaire, and the luminaire is set at a predetermined angle by aligning the laser beam with the sighting device with a laser (Japanese Patent Laid-Open No. Hei 10). -106309).
By the way, since the height of a tunnel on a motorway is usually about 7 meters, in order to attach a luminaire to the inner wall surface of the tunnel, a support arm formed by supporting the outer wall of the luminaire body on the inner wall of the tunnel has a height of 5 mm. It is done by fixing it to a place of about a meter. The angle of the luminaire is adjusted by the operator changing the angle of the luminaire with respect to the support arm.
[0003]
[Problems to be solved by the invention]
However, the curved surface of the inner wall surface of the tunnel that supports the lighting fixture is not uniform, and a slight difference occurs in the mounting surface of the lighting fixture. When a lighting fixture is attached to the mounting surface and the light source is turned on, there is a disadvantage that a difference in the irradiation direction occurs between the lighting fixtures, and the designed luminance value cannot be obtained.
[0004]
This invention is invented in view of said point, Comprising: It aims at providing the angle setting mechanism of the lighting fixture which can obtain the luminance value as a whole in a tunnel.
[0005]
[Means for Solving the Problems]
The present invention has the following configuration in order to solve the above problems. According to the first aspect of the present invention, the reflecting mirror is supported inside the lighting fixture body having an open front surface, a light source is mounted at the focal position of the reflecting mirror, and the angle is adjusted to the outer wall of the lighting fixture body. The present invention relates to an angle setting mechanism of a lighting fixture in which a support arm to be obtained is arranged.
Also, the reflecting mirror is angularly adjustably configured so as to vary the irradiation angle from the outside of the luminaire body, also in the front end opening of the reflector, is arranged a laser pointer detachably.
And the most angle of the luminaire is adjusted and supported by the support arm on the outer wall of the luminaire body, and the angle of the reflector can be finely adjusted by the laser pointer at the front end opening of the rear reflector. An angle adjustment mechanism for a lighting fixture.
[0006]
The invention according to claim 2 is configured to be variable within a range of ± 5 degrees by the angle adjuster provided at both ends of the reflecting mirror in the invention according to claim 1.
[0007]
According to the first and second aspects of the present invention, most angles of the luminaire are adjusted and supported by the support arm of the outer wall of the luminaire main body, and the laser pointer of the front end opening of the rear reflector is used. in the angle of the reflecting mirror is finely adjusted, the uniform your Keru irradiation direction to each luminaire in the tunnel, it is possible to obtain a luminance value as designed overall.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to FIGS. In FIG. 1 to FIG. 4, 1 is a luminaire main body having an open front surface, 2 is a front frame that is openably supported by a front opening of the luminaire main body 1, 3 is a front glass that is supported by the front frame, Reference numeral 4 denotes a reflecting mirror that is mounted inside the luminaire main body 1 so that the irradiation angle can be varied. The reflecting mirror 4 has an opening on the front surface and a flange 5 at the front end. Reference numeral 6 denotes a light source mounted at the focal position of the reflecting mirror 4 and is configured using, for example, a 110 watt high pressure sodium lamp.
[0009]
Reference numeral 10 denotes a support arm that is supported on the outer wall of the luminaire main body 1 so that the angle can be adjusted. The fixing arm 11 is fixed to the outer wall of the luminaire main body 1, and the hinge 12 is attached to the fixed arm 11. The length can be adjusted by adjusting the angle via the upper and lower fixed pieces 13 fixed to the wall surface in the tunnel.
Reference numeral 14 denotes a socket arranged inside one end of the luminaire main body 1, and 15 denotes a reflecting plate rotating arm arranged at one end of the reflecting mirror 4. Reference numeral 16 denotes a knob for adjusting the angle of the reflecting mirror 4 arranged at the outer end of the reflecting plate rotating arm 15. Reference numeral 17 denotes a knob for adjusting the angle of the reflecting mirror 4 disposed at the other end of the reflecting mirror 4.
By using the knobs 16 and 17, the reflecting mirror can be varied in a range of ± 5 degrees. If it is configured to be variable within a range of ± 5 degrees, the design value can be easily satisfied from the relationship between the mounting height of the lighting fixture in the tunnel illumination and the optical axis position.
[0010]
Reference numeral 20 denotes a laser pointer which is detachably disposed in the front end opening of the reflecting mirror. Reference numeral 21 denotes a support arm for mounting the laser pointer 20 so that it can be engaged with the flange 5 at the front end of the reflecting mirror 4. It is configured.
[0011]
Next, attachment of the lighting fixture to the inner wall surface of the tunnel, angle adjustment of the lighting fixture, and fine adjustment of the angle of the reflecting mirror will be described.
(1) For example, the inside of the tunnel is 4 lanes, the road width is 9.5 meters, the tunnel inner wall is 6.9 meters high, and the lighting fixtures are 7.3 meters apart at a height of 4.8 meters. Place with.
(2) In this case, most angles of the luminaire are adjusted and supported by the support arm 10 on the outer wall of the luminaire main body 1 described above.
(3) After that, the angle of the reflecting mirror 4 is finely adjusted by the laser light emitted from the laser pointer 20 disposed at the front end opening of the reflecting mirror 4 to set the irradiation direction. In this case, by making the tip irradiation position of the laser beam in the tunnel constant, the irradiation angle of each lighting fixture can be set as designed, and an overall brightness value can be obtained in the tunnel. it can.
(4) After finely adjusting the angle of the reflecting mirror, the laser pointer 20 is detached from the reflecting mirror 4, the front glass 3 is closed, and the operation is completed.
