Abstract

PURPOSE:To widen the light distribution without sacrificing the appearance of the ceiling surface by making a light source unit not protrude out of a case when an emergency lighting is not required, and making it protrude out of the case when the emergency lighting is required. CONSTITUTION:When a normal power source is turned off, the operation of a solenoid relay 5 stops and a halogen lamp 4 is lit with a storage battery. Here, a member 7 to be attracted of a light source unit 2 comes off the solenoid relay 5 and the light source unit 2 falls off with its with a member 9 to be engaged or the flange 9 of ceiling beams 14, 15 and the light source unit 2 is suspended outside a case 1. When the normal power source is turned on, the light source unit 2 is suspended within the case 1. This makes the light distribution wider without sacrificing the appearance of the ceiling surface and reduces the number of light sources to be installed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an emergency lighting fixture that is used by being embedded in the ceiling of a building or the like.

(Prior Art) As shown in FIG. 5, a conventional emergency lighting device is built into a facility plate 23 of a general lighting device 21, and an emergency light bulb 22 protrudes from the plate surface.

In the figure, 26 is a fluorescent lamp. Further, as shown in Fig. 6, it is incorporated in the back of the general lighting fixture 24, and an emergency light bulb 25 protrudes from between two fluorescent lamps 26 and 26 (see Japanese Utility Model Publication No. 59-4492). .

However, since these emergency light bulbs 22, 25 are always in a protruding state even when not in use, they significantly spoil the appearance of the ceiling surface.

Furthermore, since the above-mentioned emergency lighting equipment is incorporated into general lighting equipment, it is difficult to relocate or add to the equipment. For this reason, the following problems occurred.

For example, when changing partitions, it may not be possible to obtain the illuminance required by the Building Standards Act depending on how the partitions are installed.In such cases, emergency lighting equipment can be easily relocated or added. I couldn't do that. Incidentally, a similar device is shown in Japanese Utility Model Application Publication No. 56-50004.

The emergency lighting equipment shown in FIGS. 7 and 8 solves the above-mentioned drawbacks and is used by being embedded in the ceiling. In addition, a similar device was developed in U.S. Pat. No. 56-50004.
It is shown in the publication No.

This is a socket 28 inside a case 27 with an open bottom.
is fixed, and an emergency light bulb 29 is attached to this socket 28, so that the light bulb 29 does not protrude from the case 27. In addition, 30 ha? fCfX terminal block, 31 is a ceiling board, 32 is a ceiling support beam, 33 is a general lighting fixture, and 34 is a fluorescent lamp.

This emergency lighting equipment can be buried separately from general lighting equipment, so even when changing partitions, it is easy to install.
It can be moved to another location, and it can be expanded if necessary. Furthermore, since the emergency light bulb 29 does not protrude from the case 27, there is no risk of spoiling the appearance of the ceiling surface.

(Problem to be Solved by the Invention) However, in the above emergency lighting equipment, as mentioned above, the emergency light bulb 29 is mounted inside the case 27 so that it does not protrude from the case 27. Therefore, as shown by the symbol B in FIG. 4, the light distribution was extremely narrow and the light distribution efficiency per fixture was poor. As a result, the number of instruments needed to be arranged increased, which resulted in the problem of being economically expensive.

This invention was made in order to solve such conventional problems, and provides an emergency lighting fixture that does not impair the appearance of the ceiling surface, has a wide light distribution, and can therefore be installed in a small number of units. The purpose is

[Means to solve the problem]

A ceiling-embedded emergency lighting device according to the present invention includes a case with an open bottom, a light source unit, and a first hanging F that suspends the light source unit from the case and releases the suspension to allow the unit to fall. and a second hanging device that catches the falling light source unit and hangs it outside the case. The second hanging device consists of an electromagnetic drive unit that performs adsorption and release, and the second hanging device consists of a hooking member provided on the light source lamp and a wave holder provided on the case or ceiling for hooking the hooking member. It is made up of several members.

[Effect]

Now, for example, if the regular power supply is cut off and the emergency power supply is turned on, the electromagnetic drive unit that was operating with the regular power supply stops, and the light source of the light source unit is turned on by the emergency power supply, the member to be attracted will separate from the unit. However, the light source unit falls under its own weight, and the hooking part of the unit is hooked to the hooked part of the case or ceiling. As a result, the light source unit is suspended outside the case. In this state, the light source unit protrudes from the case, so the light distribution of the light source becomes wider.

Also, the regular power source is turned on and the emergency power source is turned off.
When the electromagnetic drive unit is activated by the regular power supply and the light source that was turned on by the emergency power supply goes out, when the member of the light source unit suspended outside the case is pressed against the "triiff drive unit, this unit As a result, the light source unit is suspended within the case. In this state, the light source unit does not protrude outside the case, so the appearance of the ceiling surface is not impaired.
