JP5411220B2 - Inductive reflector - Google Patents

Description

  The present invention relates to a guide reflector installed on the optical axis of a lighting fixture.

  Street lamps that use mercury lamps, sodium lamps, etc. are not only used as lamps that illuminate directly underneath or in the vicinity of the lamps, but also as guide lights that can be guided by drivers to determine the target passing point by viewing them from a distance. There is a role.

  A general street lamp uses a fluorescent light of a bar-shaped omnidirectional light source, a mercury lamp or a sodium lamp of a spherical omnidirectional light source, etc., so a guide reflector is not necessary and is not installed at all.

Japanese Patent Laid-Open No. 10-162626

  The problems to be solved by the present invention are various due to problems such as glare and excessive diffused light since visual observation from a higher place than the installation position of street lamps was also considered due to the importance of vehicle inductivity. It has an influence.

  In the future, lighting will continue to save energy, and there will no doubt be the development of lighting devices with new lighting structures. As the lighting of LEDs, etc. progresses, it is thought that the amount of input energy will be reduced and the light emitting area will be reduced. Further, the irradiation area is reduced, for example, by setting the irradiation angle of the radiated light of the street lamp to a required angle below the horizontal to save power. The road surface directly under the lighting fixture becomes very bright, but the visibility of the light emitting surface from the road surface away from the lighting fixture becomes worse, so the visibility from the road surface away from the lighting fixture is improved and visibility and inductivity are improved. It is to provide a high induction reflector.

  In order to solve the problem, a guide reflector is arranged in the same direction as the lamp axis on the lamp axis extension line of the radiated light of the street lamp, and a part of the irradiation light or reflected light from the light source is used in the same manner as the external lighting sign The light is diffusely reflected on the reflector to prevent glare and excessive diffused light, and as with externally illuminated signs, it is not dazzling, but a street lamp with excellent visibility from a distance is completed.

  If the guide reflector of the present invention is installed in a street lamp, the illumination angle of the street lamp can be narrowed. Therefore, if a high-reflectance reflector or an irradiation light control reflector is arranged inside the street lamp, the conventional three minutes Road surface safety can be ensured with power consumption of 1 or less.

  If the lighting angle of the street light with the above reflectors installed inside the street light fixture is set to a narrow angle (about 60 degrees), a light bulb with the same brightness and about one-sixth the power consumption of the current light bulb is sufficient. If the installation interval is narrow, the radiated light from the street light will not be directly incident on the driver's or pedestrian's field of view, and glare and dazzling will be almost avoided, and the best lighting design will be possible without leaking light to neighboring houses and lower floors .

  As described above, visibility on the road is enhanced by reducing the illumination angle of the street lamp. By installing the guide reflector of the present invention, visibility from a distant place can be improved, and a street light that functions as a guide light can be provided although it is not dazzling as well as an externally illuminated signboard.

  In addition, by writing letters, symbols, numbers, etc. on the surface of the guide reflector of the present invention, it is possible to display place names and town names more detailed than current road signs at night, so that not only drivers but also pedestrians can obtain information. Can do.

  And since the power consumption of street lights can be reduced, solar panels can be installed individually and can be turned on without power, so that each individual can be turned on independently in the event of an earthquake or power outage, thereby protecting the safety of the city.
