Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a clean room partition panel with a lighting device that provides necessary lighting to a working position.

[Conventional technology]

In general, conventional lighting devices for clean tunnel type vertical laminar flow clean rooms and the like include those shown in FIGS. 4 to 6, for example.

1 is the ceiling of the structure, and 2 is a filter, which is provided below the ceiling 1 to filter air sent from a duct (not shown) to remove dust and the like. 3 is a lighting lamp, and 4 is a floor of the structure.

FIG. 4 shows a case where the illumination lamp 3 is attached to the lower surface of the filter 2 and on the downstream side with respect to the air flow.

FIG. 5 shows a case where the illumination lamp 3 is provided on the same surface as the filter 2.

FIG. 6 shows a case where the illumination lamp 3 is provided on the side surface of the clean tunnel section, which is the space between the filter 2 and the floor 4.

[Problem that the invention attempts to solve]

However, in the case of such a conventional lighting device, in the case of FIG. As a result, the airflow is disturbed, and furthermore, dust and the like tend to adhere to the illumination lamp 3, which affects the cleanliness of the air on the downstream side.

In the case of FIG. 5, if the area of the filter 2 is increased in order to improve the cleanliness of the air, the irradiation area of the illumination device becomes smaller, making it impossible to obtain an appropriate illuminance on the work surface.

In the case of FIG. 6, there is almost no disturbance in the vertical laminar flow, but there is a drawback that the laminar region (clean region) of the air is disturbed when replacing the lighting lamp 2, cleaning, etc.

This invention was made by focusing on the problems in the conventional example as described above, and aims to solve the above problems by providing a lighting device in the partition panel.

[Means for solving problems]

This invention includes a lighting device on a panel that closes off between the clean room and other rooms, the front cover of the lighting device does not protrude much beyond the surface of the panel on the clean room side, and the rear cover of the lighting device This is a partition panel for a clean room equipped with a lighting device, which faces into another room, and whose rear cover can be opened and closed freely.

[Effect]

According to this idea, once the clean room and other rooms are closed off with a panel, the lighting system setup is completed. Furthermore, since the lighting device does not protrude significantly toward the clean room side, it does not disturb the air flow in the clean room, and even when inspecting the lighting device, the rear cover facing other rooms is opened and closed, so the air flow in the clean room is not disturbed.

Furthermore, since the lighting device is installed on the panel, it does not adversely affect the area of the filter on the ceiling or the like, and the area of the lighting device and the area of the filter can be independently and suitably set.

Furthermore, even when there is insufficient illumination from the ceiling or the like or when illumination cannot be obtained from other parts, the working position can be appropriately illuminated.

〔Example〕

This invention will be explained below based on the drawings. 1 and 2 are diagrams showing an embodiment of the present invention.

First, to explain the structure, FIG. 1 is a perspective view showing an example of a clean tunnel type vertical laminar flow clean room, where 1 is the ceiling of the structure and 4 is the floor. 2 is an air filter;
This is a device installed nearby that removes dust and the like from the air supplied from the duct 1a to produce clean air. A partition panel 5 is installed between the ceiling 1 and the floor 4. Reference numeral 6 is a clean room (clean tunnel), which is a space defined by the filter 2, the partition panel 5, and the floor surface 4. Clean air is supplied vertically downward from the filter 2 into the clean room 6 in a laminar flow. Reference numeral 3 denotes a lighting device, which is attached to the partition panel 5. 7 is a utility space in which a partition panel 5 is used for maintenance and adjustment of the lighting device 3, etc.
This is an outdoor space that is cut off from the clean room 6 by.

Reference numeral 11 denotes a front cover of the lighting device 3, which is made of a translucent glass plate or a resin plate, such as transparent or milky white, and is fitted into the window portion 5a of the partition panel 5 via a gasket 12. There is. The gasket 12 is made of rubber or the like and prevents air, paulownia dust, etc. from leaking from the utility space 7 to the clean room 6 side. Reference numeral 13 is an illumination light (in this embodiment, a fluorescent light), 14 is a socket thereof, 15 is a socket base for holding the socket 14, and 16 is a ballast for the fluorescent light. 17 is a reflector, and 18 is a handle, which is provided on the reflector 17 for convenience in removing the reflector 17 when servicing the illuminating light 13.
Reference numeral 19 is a rear lid, which can be opened and closed by a hinge 20.

The lighting device 3 is constituted by the above-mentioned parts 11 to 20. The lighting device 3 is attached to the partition panel 5 by bolts 21.

The front cover 11 of the lighting device 3 does not protrude much beyond the surface of the panel 5.

Here, the phrase "the front cover does not protrude significantly" means excluding cases where the front cover protrudes to the extent that it disturbs the laminar flow of the clean tunnel, etc., to the extent that it causes trouble in the use of the clean tunnel, etc. Therefore, if it does not cause any trouble in use, it does not protrude significantly.

Next, the effect will be explained.

The illumination lamp 13 is installed at a predetermined angle with respect to the front cover 11 so that the illumination angle is such that a predetermined position in the clean room 6 is illuminated intensively.
Because it is installed in
The reflector 17 reinforces the illumination of the illumination lamp 13.
In addition, the front cover 11 is attached to the partition panel 5.
Since it does not protrude from the surface of the clean room 6 side, the vertical laminar flow of clean air blown out from the air filter 2 is not disturbed.

When replacing or cleaning the lighting lamp 13, open the rear cover 19 by rotating it in the direction of the arrow about the hinge 20, and then remove the reflector 17 by holding the handle 18. Maintenance etc. can be done easily.

FIG. 3 shows a second embodiment.

Note that the same parts as in the above embodiment are given the same reference numerals, and redundant explanation will be omitted. This embodiment is different from the front cover 11 of the lighting lamp 13 in the previous embodiment.
By arbitrarily changing the angle of the illumination lamp 13, it is possible to set the irradiation angle of the illumination lamp 13 such that appropriate illuminance can be obtained even at the working position in the clean room 6. The arm 31 fixed to the socket base 15 has one end that moves left and right in a pendulum shape along an arcuate groove 32 provided in the side plate (not shown) of the lighting device 3.
The irradiation angle of the illumination lamp 13 can be changed as appropriate. 33 is a fixing screw, and the arm 31
By fixing the socket base 15, the socket base 15 is fixed at a desired angle. The front of the reflector 17 is moved left and right in a pendulum-like manner along the circular arc groove 34 provided on the side plate according to the rotation angle of the socket base 15, and after the socket base 15 is fixed, it is moved to an appropriate position with the fixing screw 35. Just keep it fixed.

[Effect of idea]

As explained above, according to this invention, by defining the clean room with panels, the installation of the lighting device is completed at the same time, so the construction period for the clean room can be shortened. Further, the lighting device does not disturb the airflow in the clean room, and the clean room side is not opened or closed during inspection or removal of the lighting device, so the airflow is not disturbed.

Furthermore, since the lighting system and the clean room filter are independent, each can be set to the optimum condition individually, and even if there is no or insufficient lighting from other areas, the clean room filter can be It also has the effect of providing appropriate lighting for the working position.
