Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a lighting device installed on the ceiling of conference rooms, classrooms, etc.

Recessed straight tube fluorescent lamp lighting fixtures are common indoor lighting fixtures for conference rooms and classrooms of various vocational schools. There are various types of lighting equipment, including those with louvers that regulate the direction of the fluorescent lamp's light, and those with translucent covers that soften the light of the fluorescent lamp, and are suitable for the indoor environment. is attached to the ceiling.

However, the indoor lighting environment created by such lighting equipment is uniquely determined, and therefore, if the indoor equipment is changed or the purpose of the room is changed, the lighting environment will not match the changed indoor lighting. Sometimes. On the other hand, it is unreasonable and uneconomical to install new lighting equipment on the ceiling that is compatible with changes in indoor equipment or usage.

For this reason, lighting systems have been developed and put into practical use, in which lighting fixtures are mounted on the ceiling, the lighting format of which can be easily changed. The lighting equipment of this lighting system is a box-shaped fixture with an opening at the bottom that is fixed to the ceiling, and lighting units, louvers, and covers for multiple types of lighting fixtures of the same size are prepared to form one common fixture body. One type of lighting unit and louver or cover are installed in a replaceable manner. Incidentally, the lighting unit is equipped with a light source such as a straight tube fluorescent lamp or an incandescent lamp, lighting means thereof, a reflective shade, and the like.

With this lighting system, you can easily change the ceiling lighting fixtures to various lighting types depending on the room environment and purpose by simply selecting the type of lighting unit, louver, and cover that will be attached to the ceiling fixture body. It is also economical because the main body of the instrument is common.

By the way, the lighting fixtures in the above lighting system can be easily changed to various types of lighting, but once the type of lighting unit, louver, or cover to be attached to the fixture body is decided, The lighting form of a lighting fixture is still uniquely determined, just like a general recessed lighting fixture, and therefore, the following problems have arisen, especially in indoor lighting for conference rooms and classrooms that are used for multiple purposes.

With the recent informationization of society, meetings are now being held in conference rooms using various information devices such as PJ screens. If a lighting fixture that brightly illuminates the entire room is used for lighting such a conference room, there will be a problem that the entire room will be bright and the screen will be difficult to see in a conference using a screen such as a PJ screen. Therefore, in conference rooms where meetings using screens are frequently held, in addition to lighting equipment that brightly illuminates the entire room, special lighting equipment that is suitable for screen conferences is installed, and this is used for screen conferences. I try to use it only when I want to use it, but this results in a miscellaneous lighting equipment in the room and it is troublesome to use it properly.

In addition, lighting fixtures are installed on the ceilings of classrooms in vocational schools, etc. to brightly illuminate the entire room, but classrooms are often used for multiple purposes such as studying books, learning OA equipment, and giving lectures. Currently, it is practically impossible to change the lighting equipment in classrooms to suit the purpose of use of the classroom, and depending on the purpose of use of the classroom, there are many inconveniences such as the classroom being too bright. there were.

For this reason, there has been a need for a lighting system that can be easily changed to create an indoor lighting environment suitable for various purposes.

The present invention has been made in view of the above-mentioned needs, and includes a common device body with an open bottom box shape, and a plurality of devices of the same size that are removably attached to the device body with the same mounting structure. An independent lighting unit, a frame-like frame that is removably attached to the opening at the bottom of the fixture body, and a transparent frame that is of a common size and is removably attached between the frame and the lighting unit to close the lower part of the opening of a single lighting unit. It is characterized by being equipped with a light unit. The plurality of lighting units in this invention are of the same type or different types, each equipped with a light source such as a fluorescent lamp or an incandescent lamp, or a lighting means thereof, and the light-transmitting unit is located directly below the lighting unit, It is a louver or translucent cover that changes the direction and brightness of the light from the light source of the lighting unit.

Therefore, by selecting the type of lighting unit and translucent unit, the lighting fixture can be easily changed to various types of lighting. In addition, by selecting whether or not to blink multiple lighting units built into the fixture body, multiple types of lighting formats can be flexibly selected from one lighting fixture, making it an excellent lighting system for rooms used for multiple purposes. can be provided.
