Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a retractable lighting device capable of protruding and retracting a lighting device from a ceiling surface, a wall surface, or the like.

(Prior art)

2. Description of the Related Art Conventionally, most lighting fixtures mounted on a ceiling or the like are of a fixed type, and there is no change in the position when lighting is turned on or off. Here, when the lighting equipment is turned off, the lighting equipment is in a state of being protruded from a ceiling or the like, and thus is not flush with the ceiling surface, and may press the room space. For this reason, it has been considered that the lighting fixture is buried in a ceiling or the like in advance and attached.

According to this, the flushness of the ceiling occurs, and the room space can be enlarged.

[Problems to be solved by the invention]

However, in the above structure, the light source of the lighting fixture is disposed above the ceiling surface, and the irradiation range at the time of lighting is reduced, so that the light amount may be insufficient compared to the case where the light source is protruded to the ceiling. In addition, in order to attach hoods and louvers along the ceiling surface to obtain uniformity with the ceiling surface,
This promotes the light quantity shortage. For this reason, it is necessary to increase the number of lighting fixtures, and it is not possible to apply lighting fixtures efficiently. Further, since the hood is formed of a transparent or translucent member, and the louver is formed of a lattice-shaped member, unlike the material of the ceiling surface, there is no sense of unity with the ceiling surface when not in use, and the appearance is poor. .

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a storage luminaire capable of efficiently irradiating a light source and generating a flush and integral feeling with a partition member when not in use.

[Means for solving the problem]

The housing lighting device according to the present invention has a casing attached to a partition member constituting a ceiling surface, a wall surface, and the like, and is attached to the casing, has a substantially L-shaped cross section, holds a light source between the L-shaped portions, and holds the light source inside the casing. It is rotatable from a storage position stored in the partition to a use position protruding from the partition member, and in the storage position, one side of the L-shape is arranged flush with the partition member to shield the light source from the room,
A luminaire main body including a pair of blocking members for arranging the light source on the indoor side with the respective sides abutting each other at the use position, and moving means for rotating the luminaire main body to the storage position and the use position And

[Action]

According to the present invention, when the lighting fixture body is used, the light source is turned on while being protruded from the casing by the moving means. Thereby, the irradiation range is expanded, and the lighting fixture can be used efficiently.

On the other hand, when the lighting fixture body is not used, the light source is turned off and the lighting fixture body is stored in the casing by the moving means. Since the casing is buried in a partition member such as a ceiling, the lighting fixture body does not protrude from the partition member. Also, in this stored state, the shielding member is flush with the partition member and shields the lighting fixture body,
Room space can be expanded. Furthermore, if the shielding member is made of the same material and the same color as the partition member, a sense of unity is created between the partition member and the shield member, and the appearance is good.
