Description

[0001] Lighting Apparatus for GMP [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus for GMP (Good Manufacturing Practice) capable of being embedded in a ceiling, and more particularly, to a lighting apparatus for GMP having a cover detachable from an upper or upper surface.

Generally, even in a manufacturing process of a product requiring advanced quality such as a semiconductor chip, a microelectronic device, and a medicine, even a minute environmental condition greatly affects the quality of a product being manufactured. Therefore, the manufacturing process of such a product is performed in a clean room free from dust and germs, and the entrance and exit of the clean room and the devices and facilities installed therein must satisfy special requirements to prevent foreign contaminants from penetrating. For example, lighting fixtures and switches used in clean rooms for manufacturing pharmaceuticals need to comply with GMP (Good Manufacturing Practice) certification requirements. GMP is a company that manufactures and supplies high-quality pharmaceuticals, including its structure and facilities, in the management and quality control of all processes from the purchase of raw materials and materials of pharmaceuticals to the manufacture, packaging and shipment Which is the standard of practice.

For example, in a clean room for pharmaceutical production, a GMP lighting fixture conforming to Good Manufacturing Practice (GMP) standards is installed for indoor work. In this case, since the GMP lighting device for the room is installed through the ceiling, it is important to maintain the airtightness of the ceiling and the lighting device in order to block pollutants or outside air that may enter the room from the ceiling. In order to maintain such airtightness, the GMP lighting apparatus has a structure in which a plurality of airtight members and / or fastening bolts are tightly fastened.

On the other hand, due to the characteristics of the airtight structure of the GMP luminaire, when maintenance work for replacement and repair of the luminaire, ballast, etc. of the luminaire is performed, the operator must separate the entire upper frame of the luminaire installed in the ceiling from the subframe Therefore, a considerable time is required for maintenance. That is, there is a problem that it takes a long time to work on the GMP lighting fixture, which makes it difficult to work easily.

In addition, since the above-described GMP lighting apparatus generally uses a fluorescent lamp as the light emitting unit, the light emitted from the fluorescent lamp diffuses or disperses in all directions. Therefore, in order to increase the efficiency of the lighting apparatus, A reflective plate for guiding light into the clean room is required.

In addition, since the fluorescent lamps generate a large amount of heat, the lifetime of the fluorescent lamp and the related circuit board may be shortened, and in some cases, a heat radiating device may be further required to emit a large amount of heat generated from the fluorescent lamp. For this reason, manufacturing cost of a lighting fixture for GMP using a fluorescent lamp may increase manufacturing cost and maintenance and maintenance cost.

In the conventional GMP lighting fixture, since the entire upper frame of the lighting apparatus must be separated from the lower frame at the time of maintenance and repair work, there is a problem that the operation time is long and the ease of operation is poor. In addition, when a fluorescent lamp is used for a GMP lighting apparatus, a large amount of heat is generated from the fluorescent lamp, and a reflector for preventing dispersion of light of the fluorescent lamp is required, which increases manufacturing cost and maintenance and maintenance costs.

The present disclosure provides a lighting fixture for GMP capable of solving the problem caused by heat generation of the light emitting portion and reducing the manufacturing cost by using the LED module as the light emitting portion.
