Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a movable lighting cover whose irradiation direction can be controlled.

[Background of the invention]

Recently, the mechanization of office work has progressed, and C
Many RT display devices have been installed, but at the same time, the light source of the lighting fixtures installed on the ceiling in the office often reflects on the display screen of the CRT and becomes a hindrance to work. became. Therefore, we attached lighting covers made of reflective shades and louvers to existing lighting equipment.
The direction of light irradiation is controlled to prevent the light source from being reflected on the CRT display screen. Conventional lighting covers of this type have been mounted by sharing the reflector mounting screws of existing lighting equipment, or by clamping the fluorescent lamps with clips provided near both ends of the lighting cover. The former is fixed to the reflector of the lighting fixture, so the positional relationship between the lighting fixture and the CRT display screen cannot be adjusted by the direction of light irradiation, and the latter is attached to a fluorescent lamp with both ends held by small base pins. Even if it was possible to adjust the direction of light irradiation, it was extremely dangerous to apply a load.

[Purpose of the invention]

An object of the present invention is to obtain a movable lighting cover that supports the load with the lighting fixture itself, allows the louver to be attached and removed, and allows the direction of irradiation to be controlled.

[Summary of the invention]

The movable lighting cover of the present invention is a movable lighting cover that controls the irradiation direction of a lighting device, and includes: an edge of the socket insertion opening of the lighting device reflection plate; an edge of the curved surface forming portion of the reflective shade that constitutes the movable lighting cover; or the edge of the opening provided in the curved surface is rotatably clamped. The weight of the reflective shade and the louver is supported by the lighting fixture reflection plate via the L-arranged locking fittings, so that the direction of irradiation of the lighting fixture can be controlled.
