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 an emergency power source is turned on to light a halogen lamp 4 of a light source unit 2 and to simultaneously actuate a solenoid relay 9, a female member 7 placed on a receiving members 8, 8 and fitted with a male member 5 of the light source unit 2 is attracted to the relay 9. As a result, the male member 5 is removed from the female member 7 by the weight of the light source unit 2 and the light source unit 2 falls off. A detent member 11 of the light source 2 is caught with a catch member 12 or an ornamental rim 12 of a case 1. The light source unit 2 is suspended outside the case 1. When an emergency light source 10 is turned off, the light source unit 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 a partition, depending on how it is installed, it may not be possible to obtain the illuminance required by the Building Standards Act.In such cases, emergency lighting equipment can be easily relocated. It was not possible to add more.

The emergency lighting equipment shown in Figure 7° solves the above-mentioned drawbacks and is used by being embedded in the ceiling.

Incidentally, a similar device is shown in Japanese Utility Model Application No. 5650004.

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 is a power terminal block, 3
1 is a ceiling plate, and 27a is a decorative edge of the case 27.

This emergency lighting equipment can be buried separately from the general lighting equipment, so it can be easily relocated even if the partition is changed, 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 described above, the emergency light bulb 29 is mounted inside the case 27 so that it does not protrude from the case 27, so it is indicated by the symbol B in FIG. As such, the light distribution was extremely narrow and the light distribution efficiency per fixture was poor. For this reason, there is a problem that the number of instruments to be arranged increases and it becomes economically expensive.

This invention was made to solve these conventional problems, and provides an emergency lighting fixture that does not change the appearance of the ceiling surface, has a wide light distribution, and can therefore be installed in a small number of units. [1 point]

(Means for Solving the Problems) A ceiling-embedded emergency lighting device according to the present invention includes a case with an open bottom, a light source unit, and a light source unit suspended in the case, and the suspension is released. It consists of a first hanging device that allows the light source unit to drop, and a second hanging device that catches the falling light source unit and hangs it outside the case.The first hanging device is attached to the top of the light source unit. When the convex member and the convex member are fitted from the bottom, the fitted piece of the left U opens due to the weight of the light source unit as it is, and the concave member is disposed above the concave member,
In addition, an electromagnetic drive unit for attracting and releasing the same member is attached to the case to hook the concave member, and when the concave member fitted with the convex member is placed, the fitted pieces on the left and right of the concave member are attached to the case. The second hanging device includes a pair of left and right receiving members that prevent the light source unit from opening due to its own weight, and the second hanging device includes:
It is composed of a hanging member provided on the light source lamp and a hanging member 1F provided on the case or ceiling for hanging the hanging member 1.

[Effect]

When the emergency power is turned on and the light source of the light source unit is turned on, and the electromagnetic drive unit is activated, the concave member fitted with the convex member of the light source unit is attracted, so that the convex member is not affected by the weight of the light source unit. The unit comes off from the concave member and falls.

Then, the hooking member of the light source unit is hooked to the wave IF member on 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.

After turning off the emergency 7tt source, turning off the light source of the light source unit, and stopping the operation of the electromagnetic drive unit, fit the convex member of the light source unit suspended outside the case into the concave member from below, and leave it as it is. In this state, the left and right fitting pieces of the concave member are placed on the receiving members provided in the case. In this case, the concave member is blocked by the receiving member and does not open to the left or right, so that the convex member does not come off from the concave member. 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 does not look like H1.
