Description

Detailed explanation of the device

The present invention relates to a structure in which a power socket or connector for an external power source is attached to a ceiling light to supply power from the power socket or connector for an external power source to turn on the ceiling light in the event of a power failure.

Conventionally, emergency lights in the event of a power outage have become flashlights or lighting fixtures that use power sources such as batteries and generators, and such emergency lights have not been able to illuminate the entire room brightly.

It is necessary to illuminate the entire room brightly in order to maintain a normal family life, and it is necessary to illuminate the entire room brightly in order to eliminate psychological anxiety even in a life with a long power outage such as a disaster. There was a need for lighting at the location of existing ceiling lights.

Ceiling lights are required to illuminate the entire room in order to eliminate psychological anxiety in the event of a long-term power outage during a disaster, and ceiling lights can be supplied with external power to the ceiling lights installed at existing locations. The purpose is to turn on the light and illuminate the entire room brightly.

A power socket or connector is provided between the hook ceiling cap, which is a role for suspending the ceiling light from the ceiling and supplying commercial power, and the electronic circuit of the ceiling light, and power is supplied to the secondary power supply device.

The power supply method for the secondary power supply is to connect the power cable consisting of the power cord and power plug to the power socket or connector attached to the ceiling light, and connect the power cable to this power plug, such as a battery, generator, or capacitor. Connect the next power supply to supply power. (Inverter is required for connection with battery)

Ceiling light hook The ceiling cap and the newly installed power socket or connector should be equipped with a switch to prevent electric shock when the power failure is resolved and to prevent fire when the secondary power supply is supplied with power. Insulate.

The switches used to insulate the commercial power supplied from the ceiling side from the power of the secondary power supply are mechanical switches, manual changeover switches, electromagnetic valves, electrical switches using relays, etc. However, since we want to be able to perform reliable switching, we will insulate with a manual changeover switch that has a simple structure and can be reliably insulated.

Connect the power plug of the power cable that connects to the attached power socket or connector to the secondary power device such as a battery, generator, or capacitor. (In the case of a battery, an inverter is required and the power plug connection is an inverter)

In the event of a power failure, simply attach the power cable to the power socket or connector of the ceiling light and switch it with the changeover switch, so you can easily connect without the need for tools.

The function of the ceiling light can be easily secured by using the electric power of the secondary power supply device.

Since the height of the ceiling light does not change, the brightness of the entire room can be ensured to be the same as the brightness in normal times.

Since the hook ceiling body attached to the ceiling and the hook ceiling cap of the ceiling light are insulated by a switch, there is no worry of fire, short circuit, electric shock of other household appliances even in the event of a power failure due to an earthquake or flood, and a secondary power supply. You can use the power supply of the device with confidence.

The ceiling light hook ceiling cap connected to the ceiling hook ceiling body is insulated by a changeover switch, so even if the first floor is submerged due to flood damage, it can be used anywhere if there is a secondary power supply. It can be expected to be used on the second floor for emergency evacuation in the event of a flood.

The ceiling light with an emergency power supply mechanism has a structure in which a changeover switch 7 for supplying power to a secondary power supply device and a power socket or connector 8 are connected to a part of the ceiling light 4 currently on the market. A power cable 9 composed of a power cord 11 and power plugs 10 and 12 is connected to the power socket or connector 8 to supply power to the secondary power supply device. Regarding the power cable 9, a method of storing the reel cord in the ceiling light 4 and storing the power cord 11 and the power plug 12 without using the power socket or the connector 8, or connecting the power cord 11 and the power plug 12 directly to the main body. However, in consideration of the complicated structure and the increase in the weight of the ceiling light 4, a method of separating the power cable 9 by using the power socket or the connector 8 is adopted.

At the time of secondary power supply, the sealing cap 5 of the sealing light 4 and the power socket or connector 8 are insulated by the changeover switch 7 and caused by electric shock or backflow of electricity at the time of recovery from a power failure or when the power of the secondary power supply is supplied. It is necessary to prevent the fire of home appliances.

The changeover switch 7 may be a mechanically structured switch, a manual changeover switch, an electric switch using an electromagnetic valve, a relay, or the like, and in the case of DC power supply, a method of preventing backflow by a diode or the like can be considered. , I decided to insulate with a manual changeover switch that has a simple structure and can be reliably insulated.

AC power has two polarities, grounded side and non-grounded side, and the outlet side has the same polarity, but many people who use electrical appliances can use AC power on either the grounded side or the non-grounded side. Therefore, it is considered that there is not much recognition of polarity. In the commonly used ceiling body, the polarity is specified for the connection on the back side (contractor side), but the polarity is not specified on the front side (user side), and it is common. In many cases, a non-polar ceiling cap is used for the ceiling cap of the ceiling light, and the ceiling light lights up regardless of whether it is connected to the grounded side or the non-grounded side. I will. In addition, considering that there may be incorrect wiring by the contractor, it is necessary to use a multi-pole double-throw switch with two or more circuits for the changeover switch 7 to ensure reliable insulation and changeover.

When using AC power, the switch is generally attached to the non-grounded side and not to the grounded side, and the polarity of commercial power is often not determined in the equipment used as described above. In consideration of the above, it is desirable to use a switch 7 for switching two or more circuits at the same time when the secondary power supply device uses AC power. Since the wiring used to supply commercial power and AC power of the secondary power supply is two circuits, one on the grounded side and the other on the non-grounded side, it is reliable to use a two-pole double-throw switch that can switch between the two circuits at the same time. Need to insulate and switch. (See Figures 2 and 6)

When using DC power, the switch is generally installed on the positive side and not on the negative side, as in the case of AC power connection. Commercial power has a polarity in the equipment used as described above. Considering that it is often undecided, and because we want to switch between the AC power of commercial power and the DC power of the secondary power supply at the same time, the changeover switch 7 when the secondary power supply uses DC power has 4 or more circuits. It is desirable to use a switch that switches at the same time. The wiring used to supply the AC power of commercial power is two circuits on the grounded side and the non-grounded side, and the wiring used to supply the DC power of the secondary power supply is two circuits on the plus side and the minus side. It is necessary to perform reliable insulation and switching by using a 4-pole double throw switch that can switch the wiring of 4 circuits at the same time. (See Figures 3 and 6)

When the secondary power supply is AC, the connection terminals 7a and 7d of the changeover switch 7 are connected to the ceiling cap 5 of the ceiling light 4, and the connection terminals 7b and 7e are the AC power connection 14 of the electronic circuit 13 of the ceiling light 4. By connecting the connection terminals 7c and 7f to the power socket or the connector 8, the changeover switch 7 switches between the commercial power and the power of the secondary power supply to turn on the ceiling light 4. (See Fig. 2, Fig. 4, Fig. 6)

When the secondary power supply device is direct current, the connection terminals 7a and 7d of the changeover switch 7 are connected to the sealing cap 5 of the sealing light 4, and the connection terminals 7b and 7e are the AC power supply connecting portions 14 of the electronic circuit 13 of the sealing light 4. The connection terminals 7h and 7k are connected to the DC power supply connection portion 15 of the electronic circuit 13 of the sealing light 4, and the connection terminals 7i and 7l are connected to the power socket or the connector 8 so that the changeover switch 7 can be used for commercial power. The sealing light 4 is turned on by switching between the AC power of the above and the DC power of the secondary power supply device.
The connection terminals 7c, 7f, 7g, and 7j are not connected and are used for insulation. (See Fig. 3, Fig. 4, Fig. 6)

When the secondary power supply is direct current, use the power plug 10 of the power cable 9 connected to the power socket or connector 8 and the plug, socket, and connector with claws on the power socket or connector 8 to make the plus side and minus. It is necessary to prevent incorrect connection (miswiring) on the side.

When turning on the sealing light 4, the power plug 12 for supplying the power of the secondary power supply device is a device corresponding to the secondary power supply device (generator, power storage device, battery + inverter, etc. in the case of alternating current, and battery in the case of direct current. , Mobile batteries, batteries, etc.) It is necessary to match the shape with the outlet for the output power supply.

The product of the present invention is an electric cord consisting of a power cord and a power plug by adding a power socket or connector for supplying power to a secondary power supply to a part of ceiling lights currently on the market and a changeover switch. It has an extremely simple structure of connecting wires, and all the elements used are made up of common parts, and it is possible to manufacture parts that are mass-produced, distributed, and consumed in the current market.
