In general, a function of a blind panel, which is a ceiling structure installed on a ceiling of a clean room for semiconductor manufacturing, is performed, and illumination means for illuminating the inside of the room is disposed on the side to facilitate the maintenance and repair work of the lighting facility In particular, a blind panel integrated type lighting apparatus has been proposed and used, which is capable of ensuring the durability of a supporting portion when a worker runs the upper part of the blind panel, thereby performing a safe operation.

With the recent development of the electronics industry and biotechnology, clean room facilities are increasing in precision industries such as semiconductors, computers, optical instruments, genetic engineering, and medicine manufacturing.

Such a clean room refers to a room in which suspended particles in the air in the room are controlled to a predetermined limit value or less. The clean room is generally used in a production facility, a laboratory, a laboratory, a manufacturing facility, It is used in various fields requiring high dust prevention function such as hospital medical facilities.

Generally, in such a clean room, indoor air is circulated by an air conditioner installed outdoors, and indoor air circulated through the air conditioner is passed through a filter to remove fine particles such as dust in the air.

Specifically, in the clean room, the air in the basement layer is sent to the ceiling through the airway by a circulating air-conditioning apparatus, and a certain pressure is formed in the ceiling portion, and the particles are subjected to the influence of the air pressure by the filter of the high- The filtered high-purity clean air is introduced into the room, and the air in the room is cleaned by a series of circulation processes through the tile passing through the tile having fine holes at the bottom due to the suction of the circulating air conditioner. It will be done.

At this time, a system seal for a semiconductor clean room is installed on the ceiling above the clean room.

Such system sealing for a semiconductor clean room is generally known in the art, as disclosed in Patent Registration No. 10-1728097, in which a mold bar made of aluminum material is installed in a lattice structure, and the mold bar is attached to a suspending bolt Hanging on the frame fixed to the ceiling slab.

A fan filter unit for maintaining the cleanliness of the inside of the clean room is installed at a predetermined interval at the upper end of the mold bar and a blind panel is installed in a space between the fan filter units. Lt; / RTI >

In addition, the mold bar or the blind panel is provided with an illuminator for ensuring the illuminance inside the clean room, and the fluorescent lamp, which is one example of the illumination, is exposed on the bottom of the mold bar or the bottom of the blind panel So that the room is illuminated.
