JPH0294308A - Emergency illumination fixture for system ceiling - Google Patents

Abstract

PURPOSE:To facilitate movement when partitioning is to be changed, by arranging an emergency illuminating fixture in a gap between two ceiling supporting bars, which are arranged at a certain spacing, in such a way as conjugate with a diffuser for airconditioning blowout. CONSTITUTION:A diffuser 10 for airconditioning blowout 10 is installed in a gap 9 between ceiling supporting bars 11, 12 in such a way as conjugate with an emergency illuminating fixture 4 in line therewith. Accordingly it is not particularly prominent even though put off at normal times. As the emergency illuminating fixture 4 is in a single piece placed on the ceiling supporting bars 11, 12, fitting works are easy, and movement or annexation can be made easily when the partitioning is to be changed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an emergency lighting fixture installed on the system ceiling of a building or the like.

[Conventional technology]

As a conventional emergency lighting equipment, for example,
A light bulb that lights up in an emergency as shown in Figures 1 and 4 of Publication No. 492 may be incorporated into a general lighting fixture, or a light bulb that lights only in an emergency as shown in Figure 5 of the present application. There is a special type of emergency lighting equipment equipped with a light bulb. Figure 5 shows an emergency lighting device installed on an equipment panel 8 installed at the end or middle part of a general lighting device.
is an emergency light bulb that only lights up in an emergency.

Fig. 6 is an example of a built-in emergency lighting device incorporating a conventional emergency lamp, where 6 is a fluorescent lamp that is normally lit;
7 is a general lighting fixture mounted on the ceiling support bar 11.12,
1 is an emergency light bulb that turns on only in an emergency.

The conventional system ceiling emergency lighting equipment is configured as described above, and when the normal power supply is cut off, power is started to be supplied to the emergency light bulb 1 from the separately installed emergency power supply, and the emergency light bulb lights up. It is designed to provide the specified illuminance.

(Problems to be Solved by the Invention) As mentioned above, in the conventional system, the emergency light bulbs that are not in use are always turned off in the general lighting equipment, and as shown in Figure 5, There is a problem in that the lamps are exposed in the ceiling or protrude between general lighting fixtures as shown in Fig. 6, significantly detracting from the appearance of the ceiling surface.

In addition, since emergency lighting equipment is attached to general lighting equipment or equipment panels, if the partitions are changed at the tenant's request after completion of construction, the lighting intensity specified in the Building Standards Act must be met. However, there were concerns that it was extremely difficult to relocate or add emergency lighting equipment. In addition, there were cost and process problems, such as the need for processing and installation work on equipment panels or general lighting fixtures.

This invention was made to solve this problem, and is an emergency system ceiling system that can improve the design of the ceiling surface, improve flexibility in changing partitions after completion, and improve workability. The object of the present invention is to provide a lighting equipment device for use in lighting equipment.

[Means for Solving the Problems] In order to achieve the above object, the present invention configures an emergency lighting device for system ceiling as follows.

That is, two ceiling support bars are arranged with a predetermined gap between them, and an emergency lighting fixture is arranged in the gap in series with a diffuser for air conditioning.

[Effect]

Since the structure is as described above, the emergency lighting equipment is not noticeable at all times, is easy to move when changing partitions, and is easy to install.

(Example〕 This invention will be explained below with reference to Examples.

Fig. 1 is an external perspective view of a system ceiling emergency lighting device J which is an embodiment of the present invention, Fig. 2 is a sectional view of the same embodiment, and Fig. 4 is a side sectional view of the same embodiment. , Figure 3 is the 4th
It is a sectional view seen from the direction AA of the figure.

In the figure, 1 is a halogen bulb that lights up during a power outage, 2 is a lamp socket, 3 is a reflector that hides the bottom opening of the emergency lighting device body 4 and reflects light, and 5 is the opposite side of the ceiling support bar 11.12. Ceiling material placed on the outside of the T-shaped portion, reference numeral 9 is a predetermined gap provided between ceiling support bars 11 and 12. Reference numeral 10 denotes a slit-shaped air conditioner blowout diffuser arranged in the gap in line with the emergency lighting equipment 4.

In this way, the emergency lighting equipment is arranged in the gap between the ceiling support bars and in line with the air conditioning diffuser, so it is not noticeable even if it is turned off all the time.

Furthermore, since the emergency lighting equipment is mounted singly on the ceiling support bar, it is easy to install and can be easily relocated or added when changing partitions.

(Effects of the Invention) As explained above, the present invention utilizes the gap between two ceiling support bars on which a ceiling plate or the like is installed in a system ceiling, and installs a slit-shaped air conditioning blowout diffuser therein. By arranging the emergency lighting equipment in a line, it is difficult to see the emergency lighting equipment at all times, creating a clean ceiling.Also, even if you change the partitions after the construction is completed, you can easily install the emergency lighting equipment. It can be relocated or expanded, and since the emergency lighting equipment is configured independently, it is easy to install, and has other effects such as shortening the process and reducing costs.
