The present invention relates to a multiple reflector for lighting and a lighting fixture containing the same. More specifically, the present invention relates to a lighting device that prevents light pollution and illuminates the light by guiding the light emitted from the light source of the lighting device to be irradiated diagonally downward on both sides of the lighting device. It relates to a multiple reflector for lighting that focuses light on a lighting area and prevents unnecessary waste of light energy, enabling the construction of an economical lighting fixture, and a lighting fixture including the same.

Pedestrian paths for daily health, such as trails, trails, and trekking courses, are increasing explosively due to citizens' demand for health. As the number of pedestrians increases at dawn and at night on these pedestrian paths, the installation of appropriate lighting is required to ensure the convenience and safety of pedestrians. Here, appropriate lighting can be defined as lighting that provides light of appropriate brightness necessary for pedestrians to walk or move, but has lighting distribution so as not to cause light pollution to surrounding forests or residential areas.

Meanwhile, although the use of appropriate lighting is essential for safe and comfortable use of pedestrian paths, there are many pedestrian paths without lighting at all, and even when lighting is provided, it is the same as street lights installed on general roads. Alternatively, similar types of lighting are installed, providing excessively bright lighting in high places, causing light pollution including dazzling pedestrians and waste of energy.

As such, Republic of Korea Patent Publication No. 10-2023-0104079 (published on July 7, 2023, hereinafter referred to as 'prior art document') has been proposed as a prior art document related to lighting for safe and comfortable use of pedestrian paths.

The external reflector 11 is located on the upper part of the light source 21 and includes a reflective inner surface 111 that is concavely curved upward to form a light reflection passage W surrounding the upper part of the light source 21. In order to prevent the light emitted from the light source 21 from leaking, the inlet end 11a is mounted in close contact with the lighting fixture 20. This external reflector 11 may be formed of a thin metal plate or a plastic sheet, and the reflective inner surface 111 may be formed by attaching a highly reflective film to the inner surface of the external reflector 11, or by attaching a metal or It can be formed by coating metal oxide.

The internal reflector 12 is located below the light source 21 and includes a reflective outer surface 121 that is curved to protrude convexly upward and forms a bottom part of the light reflection passage (W). This internal reflector 12 may be formed of a thin metal plate or a plastic sheet, and the reflective outer surface 121 may be formed by attaching a highly reflective film to the outer surface of the internal reflector 12, or by attaching a metal or It can be formed by coating metal oxide.

In addition, the internal reflector 12 effectively distributes the light emitted from the light source 21 according to the radiation angle, but also irradiates a certain amount of light to the floor of the pedestrian path immediately adjacent to the lighting fixture 20. The inflow end 12a is mounted on the lighting fixture 20 so that the inflow end 12a is spaced at a certain distance from the surface on which the light source 21 is installed, that is, the side of the lighting fixture 20, by a distance calculated based on the angle.

As shown in FIG. 6, a refractive surface 112 may be further formed on the reflective inner surface 111 of the external reflector 11 for effective control of upward light emitted from the light source 21.

The refractive surface 112 has a structure that protrudes from the reflective inner surface 111 to induce diffuse reflection of the upward light emitted from the light source 21 and convert it into horizontal light or downward light, and directs upward light emitted at various angles. In order to stably convert to horizontal or downward light, two slopes inclined in different directions can be formed by continuously and repeatedly connected. The refractive surface includes a straight surface as well as a round surface with a wave-like curvature.

As shown in FIG. 7, the external reflector 11 and the internal reflector 12 may be installed in a structure that can move up and down on the lighting fixture 20 so that their relative positions with the light source 21 can be changed.

More specifically, the side plate 13 on which the external reflector 11 and the internal reflector 12 are mounted is mounted on the lighting fixture 20 in a structure capable of adjusting the up and down position, and the external reflector 13 is moved up and down. Up and down movement of the reflector 11 and the internal reflector 12 can be implemented.

Therefore, by loosening the bolt and moving the side plate 13 up and down to determine the positions of the external reflector 11 and the internal reflector 12, then tightening the bolt again increases the height of the external reflector 11 and the internal reflector 12. It can be adjusted.

As shown in FIG. 8, one or more transmitting portions 113 through which light generated from the light source 21 transmits may be formed in the external reflector 11. At this time, the transmission portion 113 induces an additional lighting effect through the transmission of light and improves the aesthetics of the multiple reflector 10, and may be formed by partially cutting and opening the external reflector 11, A transparent color filter, such as cellophane, which prevents light pollution by weakening the intensity of light coming through the transmitting portion 113 and changes light into various colors, may be provided in the transmitting portion 113.

Even though the spacing between lighting fixtures (L) is relatively wide, (b) when the generation of upward light is not allowed, there are some sections that do not meet the standard value of 2 lux, but overall, an appropriate level of illuminance can be provided. This has been proven. It has been found that the range of horizontal illumination that pedestrians can use safely on actual trails by recognizing obstacles on the road is about 0.5 lux to 3.0 lux. In particular, in places that are not sensitive to upward light, (a) better illuminance can be provided by allowing some of the generation of upward light, and (b) if upward light is not allowed, install it in a place that is sensitive to upward light, but at intervals. You can also adjust to provide appropriate illuminance.

The multiple reflector for lighting according to the present invention described above and the lighting device including the same can be implemented in other specific forms by a person skilled in the art without changing the technical idea or essential features of the present invention.
