Description

[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) This invention provides a method for safely and smoothly illuminating living rooms, evacuation routes, etc. in the event of a power outage of external power due to the occurrence of a disaster such as a fire. The present invention relates to emergency lighting equipment that supports evacuation actions, and particularly to emergency lighting equipment that has a light control member such as a reflector.

(Prior Art) Conventionally, the basic conditions for this type of emergency lighting equipment have been defined as follows by the Japan Lighting Equipment Industry Association (abbreviated as JIL).

(1) Emergency lighting equipment uses a backup power source such as a fully charged emergency battery to keep the lights on for 30 minutes in an emergency, and continues to illuminate the necessary areas directly with an illuminance of ILx or higher on the floor (in the case of fluorescent lights) , 2Lx or more at room temperature).

(2) Emergency lighting equipment must have heat resistance that allows it to remain lit for 30 minutes in an atmosphere at a temperature of 140°C with a fully charged emergency lighting battery.

(3) Noncombustible materials should be used for the main parts of emergency lighting equipment.

(4) The emergency light source shall be one that can be turned on immediately by an emergency power source when the regular power supply or general power supply is cut off.

(5) Emergency lighting equipment (with a built-in battery) automatically switches to the built-in emergency battery when the general power supply is cut off, and automatically switches to the general power supply when the general power supply restores power supply. Something.

Therefore, in order to satisfy these conditions, emergency lighting equipment with a built-in battery (battery) has a battery that is charged by a general power source (external power source) during normal times, and a battery that is charged automatically in the event of a power outage of the general power source. Conventionally, devices equipped with a lighting unit or the like that lights up a lamp by switching the power source to a built-in battery have been proposed.

(Problem to be solved by the invention) However, in such conventional emergency lighting equipment,
As shown in FIG. 9, a light source such as a halogen lamp 1
and a bowl-shaped reflector 2 made of metal, for example, to reflect the future light in the desired direction to obtain the desired light distribution characteristics, are each constructed as separate bodies, so the following problems arise: be.

(1) The halogen lamp 1 has a pair of left and right terminal pins 3a.
, 3b to a socket 4 fixed to the instrument body (not shown).
By inserting each into a pair of pin holes, it is electrically connected and at the same time mechanically supported.

On the other hand, the reflector 2 is fixed separately from the halogen lamp 1 by a fixture or the like fixed to the main body of the device (not shown).

Therefore, the positional relationship between the halogen lamp 1 and the reflector 2 depends on how they are installed, and depending on how they are installed, the light distribution characteristics may vary, and in some cases, the above-mentioned emergency lighting equipment may There is a risk that the first principle condition, which is the requirement to directly illuminate the floor with an illuminance of ILX or higher (2LX or higher at room temperature in the case of fluorescent lamps), may not be met.

Therefore, in the past, in order to anticipate these errors in advance and provide some margin for the light distribution characteristics, for example, the power capacity of the battery was increased to increase the power supplied to the halogen lamp 1, thereby reducing the amount of light emitted by it. It has been increased in advance.

However, this poses a problem in that the battery becomes larger and heavier.

(2) In the emergency lighting equipment with a built-in battery, after it is attached to the ceiling or the like and before it is electrically connected to a general power source, rated power is already supplied from the battery to the socket 4.

Therefore, in this state, the halogen lamp 1 is inserted into the socket 4.
When the halogen lamp 1 is attached to the lamp, the halogen lamp 1 immediately turns on and generates heat.

For this reason, if you directly hold this halogen lamp 1 with your bare hands and attach it to the socket 4, you will not only burn your hands, but also cause the halogen lamp 1 made of quartz glass to devitrify with your fingers, etc. There is a problem in that it causes deterioration and shortened lifespan of 1.

Therefore, conventionally, a ring-shaped heat shielding cover made of silicone rubber is removably fitted around the abdomen of the halogen lamp 1 to prevent the halogen lamp 1 from being held directly with bare hands.

However, this method requires a heat shielding cover, which increases the cost, and also makes it troublesome to attach and remove the heat shield cover.

(3) Since the halogen lamp 1 and the reflector 2 are separate bodies, it is not easy to attach these 1 and 2 to the main body of the device, and there is a problem that the workability is poor.

In other words, the installation work of the halogen lamp 1 and reflector 2 requires two steps: attaching the halogen lamp 1 to the socket 4, and attaching the reflector 2 to the appliance body. After attaching it to the main body, detailed manual work is required to pass the small halogen lamp 1 through the small through hole 2a from the bottom in FIG. 9 and attach it to the socket 4, so this series of operations is not easy.
Its workability is poor.

In addition, if the reflector 2 is not attached to the instrument body using a mounting tool (not shown) as described above, first, the reflector 2 is
The lower end of the opening is brought into contact with the upper surface of the decorative frame (not shown) and the frame is simply placed.

Next, in this state, the decorative frame is attached to the instrument body, and the reflector 2 is held between the lower end surface of the socket 4 and the decorative frame from above and below.

However, in this case, the reflector 2 is supported from below by the decorative frame, so if this decorative frame is attached to the main body of the device at an angle, the reflector 2 will be tilted by the decorative frame, and the desired light distribution characteristics will be obtained. may not be possible.

Furthermore, since the decorative frame is attached to the main body of the instrument with the reflector 2 simply placed on the decorative frame in an unstable state, it is not easy to attach the decorative frame, and the workability of the attachment work is poor.

Therefore, this invention was made in consideration of these circumstances, and its purpose is to efficiently obtain the required light distribution characteristics with a simple configuration, thereby making it possible to reduce the size and weight of the light source and control. It is an object of the present invention to provide an emergency lighting device that can simplify the installation of a light member to the device body and improve the workability of the installation work.

[Structure of the invention]

(Means for Solving the Problems) In order to solve the above problems, the present invention is configured as follows.

In other words, this invention provides a light source, a light control member that controls light from the light source, a socket that is electrically and mechanically connected to the light source, a rechargeable socket, and an external power supply when energized. The light source, the socket, the battery, and the lighting unit are arranged to charge the battery by the external power source, and to supply power from the battery to the socket to light the light source when the external power source is stopped. The light source and the light control member are integrated with each other, and the light source and the light control member are integrated. shall be.

(Function) Since the present invention integrates the lamp and the light control member, in order to efficiently obtain the required light distribution characteristics when integrating the lamp and the light control member,
The light source and the light control member can be aligned easily with high precision.

Therefore, it is possible to obtain the required light distribution characteristics with high efficiency, so there is no need to supply extra power to the light source to provide a margin for the light distribution characteristics, and the battery can be made smaller and lighter. be able to.

In addition, since the light source and light control member are integrated, they can be attached to the device body in one step, and by simply attaching the light source to the socket, the light source can be electrically connected to the socket at the same time. Since it is supported together with the light control member,
The light source and the light control member can be easily attached to the instrument body, and the workability of the attachment work can be improved.

Furthermore, since the light source can be attached to the socket while holding the light control member in the hand, there is no need to directly hold the light source with bare hands.

Therefore, there is no need to burn your hands, and there is no need to cover the light source with a heat shielding member such as rubber, so it is possible to reduce costs by omitting the work of attaching and removing the heat shield member and the light source. .

(Example) Examples of the present invention will be described below based on FIGS. 1 to 8.

FIG. 3 is a vertical cross-sectional view of an embodiment in which the present invention is applied to a ceiling-embedded downlight. It has a cylindrical chassis 13 with a lid, which is the main body of the instrument that is fixed to the body.

The chassis 13 has a plurality of mounting fittings 13a, 1 on its outer peripheral surface.
3a..., as shown in FIG. 4, a battery 14 whose planar shape is approximately horizontal U-shaped, and a lighting unit that partially fits into the horizontal U-shaped recess of this battery 14. It has a built-in 15.

The battery 14 includes a plurality of storage batteries 14a, such as sealed nickel-cadmium storage batteries, in a horizontal U shape, and is electrically connected to a general power source, which is an external power source (not shown), and these storage batteries 14a...・It is constantly charged.

The lighting unit 15 charges each storage battery 14a of the battery 14 using the general power supply during normal power supply, while charging the storage batteries 14a of the battery 14 from the battery 14 during a power outage.
6 to turn on the halogen lamp 17 for a required period of time, for example, at least 30 minutes.

The socket 16 is disposed approximately in the center of a support plate 18 that supports the lighting unit 15 at its bottom, and
electrically connected to.

The socket 16 is of a plug-in type, and has a pair of pin holes (not shown) into which a pair of terminal pins 17a, 17b of the halogen lamp 17 can be inserted detachably. The halogen lamps 17 are electrically connected by inserting the pins 17a and 176b and are supported by the sockets 16.As shown in FIGS. A pair of left and right terminal pins 17a and 17b electrically connected to the electrodes of are shown at the upper end in the figure.
It protrudes outward and is integrated with a substantially truncated conical reflector 19 that is a light control member.

The reflector 19 has its top 19a on its outer surface (upper surface in the figure).
The socket 16 is formed into a substantially flat surface so as to closely connect with the lower end surface in the figure, while the lower end in the figure is entirely opened 19b.
At the lower end 19b of the opening, a flange 19ba that expands slightly outward in the radial direction is bent over the entire circumference.

The reflector 19 has an inner circumferential surface 19c formed into a parabolic surface to reflect light, and a flat top surface 19a.
A through hole 20 is bored approximately in the center of the hole 20, and a collar 20a that hangs inward is integrally provided on the inner surface of the opening periphery of the through hole 20.

Inside the through hole 20 of this reflector 19 is a halogen lamp 17 with a pair of terminal pins 17a.

Collar 20 is inserted concentrically with 17b facing upward in the figure.
They are fixed and integrated by an adhesive 21 such as cement filled in a.

That is, a pair of terminal pins 17a of the halogen lamp 17,
By inserting the halogen lamp 17b tightly into a pair of left and right pin holes (not shown) of the socket 16 in a removable manner, the halogen lamp 17 is electrically connected to the socket 16, and both the halogen lamp 17 and the reflector 19 are connected by the socket 16. Hanged.

Then, by closing the mounting opening 12a of the ceiling 12 on its indoor inner surface with the thin disc-shaped decorative frame 22 shown in FIG. The direct light from the halogen lamp 17 and the reflected light from the reflector 19 are used to illuminate the room in the lower part of the figure according to specifications through the light-transmitting window 22a.

However, as shown in FIG. 3, the lower opening end 19b of the reflector 19 is slightly floating above the inner surface (upper surface in FIG. 3) of the decorative frame 22, and a small gap is set therebetween.

The reason for this is that if the inner surface of the decorative frame 22 is brought into contact with the opening lower end 19b of the reflector 19, the decorative frame 22 will cause the reflector 19 to
When supporting the chassis 13, this decorative frame 22 supports the chassis 13.
This is to prevent the reflector 19 from being tilted by the decorative frame 22 if it is mounted even slightly at an angle, which may change its light distribution characteristics.

Therefore, according to this embodiment, since the halogen lamp 17 and the reflector 19 are integrated, when the halogen lamp 17 and the reflector 19 are integrated, the halogen lamp 17 and the reflector 19 are integrated so as to efficiently obtain the required light distribution characteristics. Positioning can be performed accurately, easily, and with high precision.

Therefore, unlike the conventional example, the required light distribution characteristics can be efficiently obtained without increasing the power capacity of the battery 14 in advance in order to provide a margin for the light distribution characteristics. It is possible to achieve weight reduction, and as a result, it is possible to reduce the size and weight of the emergency lighting equipment 11 as a whole.

In addition, since the halogen lamp 17 and reflector 19 are integrated, it is also possible to hold the reflector 19 with your hand and move the halogen lamp 1.
By simply inserting the pair of terminal pins 17a and 17b of 7 into the pair of pin holes of the socket 16, the halogen lamp 17 is electrically connected to the socket 16, and the halogen lamp 17 and reflector 19 are connected. can be supported by the socket 16. In other words, the halogen lamp 17 and reflector 19 can be socketed with one touch)1
6, the installation work can be simplified and the workability can be greatly improved.

Moreover, during this installation, there is no need to directly hold the halogen lamp 17 with bare hands, so there is no risk of burning your hands, which is safe, and prevents devitrification of the quartz glass halogen lamp 17 caused by fingers, etc. Therefore, deterioration and shortening of the life of the halogen lamp 17 can be prevented.

Further, since it is not necessary to cover the halogen lamp 17 with a heat shielding member, both the heat shielding member and the work for attaching and removing it can be omitted, and costs can be reduced.

This invention can also be applied to the emergency lighting fixture 31 of the type shown in FIGS. 6 to 8, which is directly mounted on the ceiling, and this emergency lighting fixture 31 is mainly different from the above embodiment. This is because the chassis 32 is configured to be directly attached to the inner surface of a mounting wall such as a ceiling, and the decorative frame 33 that covers the outer periphery of the chassis 32 is configured in a cylindrical shape, as shown in FIG. For example, a circular light-transmitting window 33a is formed in the center of the lower end and the shape of each component is similar to that of the previous embodiment. - Portions common to those shown in FIG. 5 are given the same reference numerals.

That is, in this embodiment as well, the halogen lamp 17 and the reflector 19 are integrated, as in the previous embodiment, so that the same effects as in the previous embodiment can be achieved.

Further, in each of the above embodiments, a halogen lamp 17 is used as a light source.
Although the present invention is not limited to this, for example, it may be a fluorescent lamp or an incandescent lamp, or any light source may be used, and furthermore, it is not limited to the size of the light source.

Further, although the socket 16 is of a plug-in type in the above embodiment, it may be of a screw-in type.

〔Effect of the invention〕

As explained above, in this invention, the light source and the light control member are integrated, so when integrating the light source and the light control member, the positioning of the light source and the light control member is adjusted so as to efficiently obtain the required light distribution characteristics. It can be done accurately and easily.

Therefore, the required light distribution characteristics can be efficiently obtained without waste.

For this reason, there is no need to increase the power capacity of the battery in advance in order to provide a margin for the light distribution characteristics as in conventional examples, so it is possible to reduce the size and weight of the battery, and by extension, the overall size of the emergency lighting equipment. It is possible to reduce the size and weight.

In addition, since the light source and the light control member are integrated, the light source and the light control member can both be supported by the socket by one simple operation of attaching the light source to the socket, which simplifies the installation. It is possible to improve workability at the same time.

Furthermore, when attaching the light source to the socket, you can hold the light control member instead of holding the light source directly with your bare hands, which helps prevent hand burns and increases work safety. Furthermore, it is possible to prevent the light source from devitrification, prevent deterioration of the light source, and extend its life.
