Abstract

PURPOSE:To concurrently allow direct illumination and indirect illumination and allow the illumination in a wide range by projecting the direct light via a window section, and performing the necessary indirect illumination with the reflected light via a reflector above a fixture main body. CONSTITUTION:The direct light from a light source in an illuminating fixture main body 1 is projected through a window section 4 provided on the main body 1 and reflected by a reflector 5 above the main body 1 to indirectly illuminate a wide range, and part of it indirectly illuminates the range different from that for the direct light through the window section 4. Direct illumination and indirect illumination can be concurrently performed, and the desired illumination over a wide range can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in direct lighting and indirect lighting/peripheral lighting devices used in parks, station plazas, etc.

[Conventional technology]

Conventionally, lighting devices used in parks, station plazas, etc. generally have a light source attached to a socket provided inside the lighting device body, and a transparent plate is installed below the lighting device body, so that the light projected from the light source can be The illuminated surface is directly illuminated through a transparent plate.

On the other hand, in the case of indirect lighting, for example, a light source is installed inside the lighting fixture, the sides of the light source are surrounded by transparent plates, and a reflective plate whose inner surface is a reflective surface is installed on the ceiling of the lighting fixture. The projected light from the light source is projected onto the reflective surface of a reflective plate provided on the ceiling surface, and is further projected downward from the reflective surface to provide indirect lighting.

[Problem to be solved by the invention]

In the lighting device having the above structure, the lighting fixtures for direct lighting and indirect lighting are configured separately, so both lighting fixtures are required to serve both direct lighting and indirect lighting.

In addition, since both types of lighting equipment are required, if the lighting equipment is mounted on the top of a pole or the like, there is a drawback that it spoils the scenery of parks, etc., station plazas, etc.

Furthermore, if you use direct lighting equipment and indirect lighting equipment,
The disadvantage is that the range of illumination is limited.

[Purpose of the invention]

The present invention was invented in view of the above-mentioned points, and is direct lighting and indirect lighting that can be used as both direct lighting and indirect lighting, illuminate a wide area, and do not spoil the scenery of parks, etc. or station plazas, etc. The purpose of the present invention is to provide a moon-shaped lighting device.

[Means to solve the problem]

The present invention has the following configuration to solve the above problems.

In other words, the lighting fixture body is provided with a socket for mounting the light source inside.

Further, a window portion for projecting direct light from the light source is provided in the lighting device body, and a reflector whose surface is a reflective surface is provided at the top of the lighting device body.

The direct light illuminates the irradiated surface below, and the reflected light projected onto the reflector indirectly illuminates a wide range of space.

Furthermore, the configuration is such that a partially different range from the direct light is indirectly illuminated with reflected light.

[Effect]

According to the direct lighting and indirect lighting/moon-shaped lighting device having the above structure, the direct light projected from the window of the lighting device illuminates the irradiated surface below the lighting device, and further illuminates the illuminated surface at the top of the lighting device. Reflectors placed in the space can indirectly illuminate a wide area of the space. Furthermore, since it is possible to use reflected light to indirectly illuminate a region that is partially different from that of direct light, the range of illumination can be greatly expanded.

〔Example〕

The invention will now be described with reference to FIGS. 1 and 3. 1st
In the figure, 1 is a lighting fixture body, 2 is a socket provided inside the lighting fixture body, and 3 is a light source attached to the sockets 1 and 2, for example, a 150 watt metal halide lamp is used.

Reference numeral 4 denotes a window portion formed in the lighting fixture main body 1, through which direct light from the light source is projected. Reference numeral 5 denotes a reflector provided at the upper part of the lighting fixture main body 1, on which the projection light from the light source is projected, providing indirect illumination. The surface of the reflector 5 is painted white, for example. Further, the shape of the reflector 5 may be any shape depending on the environment of the facility location.

In addition, a partition wall is provided in the lighting fixture body 1, and light sources are provided at the top and bottom of the partition wall, and the light source at the top illuminates the reflector for indirect illumination, and the light source provided at the top of the partition wall provides indirect illumination. The lower part of the instrument body 1 may be directly illuminated.

According to lighting devices with these structures, the area below the lighting fixture is illuminated by direct light from the light source, and a wide range of space is indirectly illuminated by reflected light projected on the reflector, and furthermore, the direct light is not the same as the direct light. Different areas can be indirectly illuminated with reflected light.

〔Effect of the invention〕

As described above, the present invention is configured such that direct light is projected from the window provided in the lighting fixture body, and a reflector is provided which is located at the top of the lighting fixture body and whose surface serves as a reflective surface. It can also serve as indirect lighting, and a single lighting fixture can illuminate a wide area.

Furthermore, since the number of lighting equipment is reduced, the scenery of parks, etc. and the 5-shaku square will not be spoiled.

Furthermore, indirect light has a unique effect of softly illuminating a range that is partially different from that of direct light.
