Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an emergency electric light, and in particular, when the power transmission to a house, etc. is stopped due to a power outage, etc., it can quickly switch to another power source for illumination. It is.

[Technical background of the invention and its problems]

Conventional emergency lights are mainly used when the power supply to a house etc. is stopped due to a power outage, etc., and are powered by a lighting device that uses batteries, and the lighting switch for the lights must be opened and closed manually. operated by

Figure 3 shows a specific example of a conventional emergency light. 1 is a case, 2
is a battery, 3 is a reflector, 4 is a lens, 5 is a light bulb, and 6 is a power switch. When the power switch 6 is closed, voltage is applied to the stain bulb 5 by the battery 2, and the lamp lights up. The lens 4 and the reflector 3 assist the brightness of the light bulb 5.

However, in the event of a power outage indoors, these conventional emergency lights do not turn on immediately at the same time as the power outage, resulting in the inconvenience of having to search for the emergency light in the dark.

[Purpose of the invention]

An object of the present invention is to quickly activate other lighting devices to provide lighting when indoor lighting is interrupted due to a power outage. □ [Summary of the Invention] The present invention provides a method for automatically controlling a light bulb, a power source for lighting the light bulb, and a switch inserted in a power supply path from the power source to the light bulb depending on whether or not power is being transmitted through a power transmission line. It is characterized by being equipped with a relay that can be switched automatically.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a basic circuit diagram of the same embodiment, where 1 is a power transmission line and 12 is a power transmission line.
is a power switch, 13 is a light bulb, 14 is a transformer, 1
5 is a rectifier diode, 16 is a relay, 17 is a light bulb, 18
is a battery.

In this case, when the power switch 12 is closed, the stain bulb 13 is turned on by the electric power sent through the power transmission line 1. However, when the power is not sent through the power transmission line 1 (during a power outage), the light bulb 13 cannot be turned on. Therefore, the relay 16 connected to the transformer 14 switches its internal switch 161 from the A side to the Open side. This causes the other light bulb 17 to be lit using another power source, such as a battery 18.

FIG. 2 shows a specific embodiment of the invention. 21 in the figure is AC
f lag, 22 is a transformer, 23 is a rectifier diode,
24 is a case, 25 is a relay, 26 is a battery, 27 is a reflector, 28 is a light bulb, 29 is a lens, and 30 is a power switch.

This item normally has 2 AC plugs plugged into an indoor outlet.
When the switch is inserted, voltage is applied to the primary side of the transformer 22 provided inside the case 24 of the emergency light, a stepped down voltage is generated on the secondary side, and the rectifier diode 23 connected to the voltage is generated on the secondary side. A DC voltage rectified by is applied to both ends of the relay 25. When voltage is applied across the internal coil of the relay 25, an internal switch 251 of the relay 25 is activated.
The back side has reeds, and the mouth side is open. Also, during a power outage, no voltage is applied to both ends of the coil inside the relay 25,
Internal switch 251 of relay 25 is closed to the mouth side.

This internal switch 25. When the power switch 30 is closed, current flows through the light bulb 28 connected to the battery 26, and the light bulb 28 lights up. Reflector plate 27
and lens 29 assist in brightness of the light bulb.
The one shown in Fig. 1 and 2 can also be used as a general flashlight because the internal switch 251 of the relay 25 is located on the opening side when power is not supplied from the AC plug 2.

〔Effect of the invention〕

Conventional emergency lights had to be turned on by a person in the event of a power outage, but the present invention detects a power outage and automatically turns on the emergency lights, making it possible to act safely and quickly in an emergency situation. It is possible.
