Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a direct/indirect combination lighting fixture in which direct lighting and indirect lighting can be freely selected and used.

[Conventional technology]

In the field of indoor lighting, as the uses of living rooms become more diverse, lighting is not only required to be functional, but also to provide quality light and create an atmosphere. For this reason, indirect lighting has come to be used in addition to direct lighting, but on the other hand, there has also been a desire to change the atmosphere of living rooms. Traditionally, indirect lighting has been provided by architectural lighting or by using specialized indirect lighting fixtures.

[Problem to be solved by the invention]

The above conventional technology requires complicated maintenance, it is not easy to replace the lamp, and the lighting equipment installed on the ceiling is
The lighting equipment was dedicated for direct or indirect lighting, and it was not possible to change the lighting method in response to changes in the purpose of the living room.

SUMMARY OF THE INVENTION An object of the present invention is to obtain a direct and indirect lighting fixture that allows free selection and switching between direct lighting and indirect lighting and facilitates lamp replacement of the indirect lighting fixture.

[Means to solve the problem]

The above object is to install a reflector in which lamps are arranged radially at intervals corresponding to the intervals between the light shielding regions, inside a body frame in which light shielding regions and light transmitting regions are arranged alternately in an annular manner. This can be achieved by providing the ring so that its center rotates to coincide with the center of the ring.

[Effect]

On the reflector plate, lamps are arranged radially in correspondence with the intervals between the light-shielding regions and the light-transmitting regions, which are alternately arranged in an annular manner on the main body frame.

If the center of the radial arrangement of the lamps on the reflector plate is aligned with the center of the ring of the main body frame, and the light-shielding area covers the top of the lamp, the direct light from each lamp will be directed to the light-shielding area of the main body frame. It is used as an indirect lighting fixture that emits only indirect light. When the reflector is rotated by a certain angle with the center of the reflector aligned with the center of the ring of the main body frame, the lamp provided on the reflector is displaced and positioned in the light-transmitting area of the main body frame. Therefore, the above-mentioned lighting fixture is used directly as a lighting fixture.

Note that even with the lighting fixture of the present invention being used as an indirect lighting fixture, the lamp can be positioned in the transparent area of the main body frame by slightly rotating the reflector plate on which the lamp is installed as described above. Since the light area is open, the lamp can be easily replaced.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

The figure is a perspective view showing the installation state during indirect lighting, and Fig. 4 is a perspective view showing the installation state (=j state) during direct lighting. In Figs.

is housed inside to form a lighting fixture. In this embodiment, the frame bottom plate 5 may be formed into a box shape with a deep rise, or the main body frame 1 may be formed into a box shape. A plurality of light-transmitting regions 7 and light-blocking regions 8 are alternately located on the surface of the main body frame 1 and are formed in an annular shape. Lamps 2 are arranged on the reflector plate 4 at intervals corresponding to the intervals between the light shielding areas 8 of the main body frame 1.
are arranged radially. In this embodiment, the lamp 2
Although four single-cap fluorescent lamps are used, the type and number of lamps are not limited to this. The reflector plate 4 is rotated by the mounting rotation shaft 6 through at least one light-shielding area interval so that the center of the radially arranged lamps 2 coincides with the center of the ring of the main body frame 1. installed.

Therefore, when the lamp 2 is located so as to cover the light shielding area 8 of the main body frame l as shown in FIG. Can be used as a lighting fixture,
When the reflector plate 4 is rotated so that the lamp 2 is located in the transparent area 7 of the main frame 111 as shown in FIG. 4, the light emitted from the lamp 2 is transmitted through the transparent area 7. Because it is reflective, it can be used directly as a lighting fixture.

According to the above embodiment, switching from indirect illumination light to direct illumination light can be easily performed using the same lighting fixture, and even in the lighting fixture that is in indirect lighting, the light-transmitting area is open. In this case, the lamp can be easily replaced by simply rotating the reflector plate slightly.

〔Effect of the invention〕

As described above, the direct/indirect combination lighting fixture according to the present invention has light-shielding areas and light-transmitting areas arranged alternately in an annular shape inside the main body frame, at intervals corresponding to the intervals between the light-shielding areas.
By providing a reflecting plate with lamps arranged radially such that the center of the radial arrangement rotates to coincide with the center of the ring, indirect light and direct light can be freely and easily selected. Therefore, the lighting can be changed in response to changes in the purpose of the living room. Furthermore, if the light-transmitting area of the main body frame is in an open state, the lamp can be easily replaced by moving the reflector even when the lamp is an indirect lighting fixture.
