Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a stand-type emergency lighting fixture that is fixedly installed on the floor.

[Conventional technology]

As a conventional emergency lighting equipment, for example,
As shown in Japanese Patent No. 0004, there are some devices in which an emergency lighting bulb and an emergency power supply device are fixed to the ceiling by themselves.

In addition, as shown in FIGS. 7 and 8, there are some that are incorporated into general lighting fixtures that are attached to the ceiling. In both figures, 31 is a fluorescent lamp, 32 is an equipment panel, 33 is an emergency lighting bulb, 34 is a general lighting reflector mounted on a ceiling-mounted T-bar 35, and 36 is a ceiling material.

(Problems to be Solved by the Invention) However, in conventional emergency lighting equipment, the emergency lighting bulb 33, which is not normally used, is always turned off and protrudes downward from the equipment panel 32, as shown in FIG. Furthermore, as shown in FIG. 8, the ceiling was exposed between two fluorescent lamps 31, which significantly impaired the aesthetic appearance of the ceiling.

In addition, since the emergency lighting bulb 33 is attached to a general lighting fixture, if the illuminance specified by the Building Standards Act is exceeded or insufficient due to changes in partitions, the general lighting fixture must be relocated or added. I had to.

However, relocation or expansion is an extremely difficult task, and even if it were possible, there was a problem in that the design of the ceiling would have to be reconfigured each time.

Furthermore, in the case of high ceilings, high-output emergency lighting bulbs were required to provide the specified floor illuminance, and the power supply equipment became expensive accordingly. Additionally, required periodic inspections and maintenance work must be done at heights, which is dangerous, inconvenient, and costly.

This invention was made in order to solve these conventional problems, and there is no danger of the ceiling surface pointing at someone's personal property, and the illuminance of the floor surface in an emergency can be obtained using a low-output light bulb. The object of the present invention is to provide a stand-type emergency lighting device that is easy to inspect and maintain, and easy to design.

(Means for Solving the Problems) A stand-type emergency lighting device according to the present invention includes a light source for general lighting provided at the top of a post fixed to the floor, an emergency power supply device provided at the bottom of the post, and an emergency power supply device provided at the bottom of the post. An emergency illumination light source is provided in the middle of the roof so that the direction of light irradiation is directed downward.

[Effect]

In this invention, the general lighting bulb is normally lit by the regular power supply, but if the regular power supply is cut off, the emergency lighting bulb is automatically turned on by the emergency power supply. , illuminating the surrounding floor.

In this invention, since the emergency lighting light bulb is not installed on the ceiling, the beauty of the ceiling surface is not spoiled, and since the light bulb is located close to the floor surface, even if it is a low output light bulb, it does not disturb the floor surface. It can be illuminated with a specified illuminance. In addition, the emergency lighting bulbs and emergency power supply are located at a low location, making it easy to inspect and maintain the sowara.

Furthermore, since the light source for general illumination and the light source for emergency illumination are separated, the illuminance and orientation performance of each light source can be freely designed independently of the other light sources.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 3.

Figure 1 is a partial cross-sectional view of the front of the stand-type emergency lighting equipment according to the embodiment, Figure 2 is a side view of the equipment, and Figures 3 and 4 are the main parts of Figure 1. This is an expanded version of

In the figure, 1 is a general lighting bulb that is lit during normal times, 2 is a socket for the same bulb with a male screw on the side, 3 is an emergency lighting bulb that is lit during a power outage, and 4 is a socket for the same bulb.

5 is a translucent glove, and the acid screw metal fitting 6 part is socket 2
It is attached to the top of the struts 11a and 11b by screwing into them. 8 is a socket stand of the above-mentioned socket 2, which is attached to the upper case 10, and this -F part case 10
is fixed to the branch offices 11a and jlb. 15 is an intermediate case. Inside this case 15, there are provided a top cover 12, a socket stand 13 for the socket 4, and a reflector plate 14 for an emergency lighting bulb. Reference numeral 16 denotes a diffusion glass, which is attached to the opening of the reflection plate 14 with decorative screws 17. 18 is a storage battery,
19 is a charging device, 20 is a base, 23 is a power line, 24 is a buried installation box, and 25 is an inspection switch, all of which are attached to the lower case 26 in advance. Pillar! 1a,l
lb is attached to a base 20 with a tightening nut 27, and the base 20 is fixed to the floor with mortar 22 together with a buried wiring box 24. 21 is a flooring material laid on the mortar 22.

With such a configuration, the general lighting bulb l is normally lit by the regular power supply. When the regular power source is cut off and an emergency occurs, the storage battery 18 is automatically activated to supply emergency power, and the emergency lighting bulb 3 lights up to illuminate the surrounding floor.

As described above, according to the lighting device of this embodiment, the emergency lighting bulb 3 is not provided on the ceiling, so unlike the conventional lighting system, the beauty of the ceiling surface is not spoiled.

In addition, since the emergency lighting bulb 3 is located at a low position, about the height of the pillars 11a and 11b, even if it is a low output one,
