Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a built-in emergency lighting system that uses a fluorescent lamp as a light source for general lighting and a small power source such as an incandescent power source for emergency lighting. It concerns instruments.

(Conventional technology) Conventionally, emergency lighting equipment built into this type of equipment was used.
For example, there is a type of C as shown in Fig. 3, which is a cross-sectional view of the Japanese Utility Model Opening Show e 1-97 te size official hat.

In the figure, 21 is the main body of the lighting fixture, 22 is a battery installed in the upper part of the main body 21 and serves as a power source in case of an emergency.
23 holds the battery 22 and a socket 24 for mounting the lamp 25 is vertically disposed at the center of the lower surface, and a block 23 attached to the block 11' (the block attached to the inner surface of the part) of the main body 21 described in 1.
6 is an inverted bowl-shaped reflector having a lamp insertion 026a in the center of the irs part; 27 is a bottomed cylindrical guide body integrally fitted to the outer periphery of the lower end opening of the reflector 26;
28 is a cylindrical portion 28e for fitting into the guide body 27;
It is a guide frame equipped with.

Since the structure is as described above, the guide body 26g of the reflector 16 and the cylindrical portion 28e of the guide frame 28 are provided with vertical height adjustment means that can select the vertical position of the reflector 26, and the lamp 25 can be arranged. The light was made variable.

[Problem that the invention seeks to solve]

-1- In the conventional emergency lighting equipment described above, when a fluorescent lamp is installed horizontally in an inverted layer reflector plate with an open bottom end, this is incorporated into a general lighting equipment for emergency lighting. Even if a louver or the like is provided at the lower end opening of the reflector and the vertical position of the reflector is adjusted by a vertical height adjustment means so that the lower end of the reflector is aligned with the lower surface of the louver, the difference between the reflector and the lamp. Since the relative position of the light source changes, the light distribution also changes, resulting in a problem that desired light distribution and illuminance distribution cannot be obtained.

This invention was made in order to solve the above problems, and is capable of achieving desired light distribution and illuminance distribution of emergency lighting in ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ft/ for emergency lighting built-in lighting fixtures, this invention The purpose is to

(Means for solving problems) A lighting fixture with built-in emergency lighting according to the present invention is:

The emergency small light source is equipped so that the height position can be selected both near the top and between the bottom ends of the reflector plate attached to the main body of the device.

[Function] In the lighting equipment of the present invention, the light distribution and illuminance distribution of the emergency lighting can be adjusted by changing the height of the small emergency light source depending on the presence or absence of the louver present at the lower end opening of the reflector. It can be maintained in a desired state.

(Embodiment) An embodiment of the present invention will be described above with reference to FIG. 1.

In FIG. 1 showing a longitudinal side view of this embodiment, T is
The ceiling where the fixture body 1 is installed in a recessed manner, the fixture body 1 is F
In the center of the In plate 2C of the box-shaped lower structure 2 with an open surface, there is also a small box-shaped two-part structure PI with an opening 11 L at the bottom.
S3 is installed integrally.

Further, 4 is an inverted dish-shaped reflecting plate attached to the entire inner surface of the lower structure portion 2, and 5 is a reflecting plate in which a lower end opening surface 4f and a lower end opening surface 5f thereof are substantially coincident with each other inside the reflecting plate 4. The louver 6, which is removably attached in the above-mentioned posture, slidably holds the V-shaped spring 7 through a holding hole 6a formed in the center of the bottom, and is vertically installed on the lower surface of the top plate 3C of the upper structure section 3. It is a metal member. Further, as a height adjustment means for the small emergency light fR9, the V-shaped spring 7 holds the lamp socket 8 of the small emergency light source 9 at the base end, while bending the front end of the image outward. A hooking portion 7k is formed to be hooked to the outer peripheral edge of the holding hole 6a, and the hooking portion 7k is formed to pass through the holes 2a and 4a formed at positions facing the holding hole 6a of the F section structure Pa2 and the reflecting plate 4. It is provided. Naru, 10 is
an emergency lighting reflector attached to the lamp socket 8;
1! is a general illumination fluorescent lamp installed in the credit sales 2c of the lower structure PIS2 and set horizontally.

With the above configuration, as shown in the first drawing,
If the louver 5 is not attached to the -F section structure R2 of the i-tool main body 1, the 1n section 10 of the emergency lighting reflector 10
The emergency small light source 9 is set so that c is in contact with the m section 4c of the reflector 4, and when the louver 5 is attached as shown in (■) in the figure, the emergency small light source 9 9
is lowered to the lower end opening surface 5f of the louver 5, that is, near the lower end opening surface 4f of the reflecting plate 4. Regarding the light distribution of the emergency lighting, the effective illuminance range should be made wider when the small emergency light source 9 is near the lower end opening surface 5f of the louver 5 than when it is in contact with the top 4c of the reflector 4. = r function, so plan the emergency lighting based on the case where it is in contact with the m section 4C, set the height position of the small emergency light #19 along this, and set the height position of the small emergency light #19 along this point, and set the height position of the small V-shaped spring. If the hook Pi$7k is hooked to the outer peripheral edge of the holding hole 6a of the metal member 6, a desired illuminance distribution can be obtained.

As shown in FIG. 2, if the spring plate portions 17b, 17b of the V-shaped spring 17 are formed into waveforms of the same wavelength, the height position of the small emergency light source 9 can be easily selected and set.

(Effects of the Invention) As explained above, the present invention has a configuration in which the height position of the emergency small light source can be selected at a desired position depending on whether there is a louver or not. Regardless of the presence or absence of emergency lighting, the light distribution and illuminance distribution of the emergency lighting can be maintained in a satisfactory state, resulting in the effect of 4416.
