Description

{EMERGENCY POWER SOURCE RELAY EQUIPMENT FOR LAMP}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an emergency switching relay apparatus for an illumination lamp, and more particularly, to an emergency switching relay apparatus for an illumination lamp in which an emergency power source side power source is used as an output power source when an abnormality occurs in a constant power source.

Generally, an emergency lighting device is installed in a place requiring illumination such as an underground facility space or an elevator car, and is used to light a fluorescent lamp when the power supply is interrupted due to sudden accident or power failure.

This emergency lighting device charges a certain amount of power to the battery through the battery charging circuit connected from the AC power source and connects the lamp connected to the high voltage generator through the AC relay so that the power of the battery is supplied to the high voltage The lamp connected to the generator is configured to light up emergency.

When the AC power is cut off, the conventional emergency power source having the above structure lights up the lamp by the relay operation, so that the battery and the emergency lighting circuit are connected until the battery is completely discharged unless normal power is supplied In addition, when the overcharge or overdischarge condition is reached due to the characteristics of the battery (battery), the battery is damaged and can not be used. Also, when the power failure time is longer than the emergency operation time of the battery, the battery is completely discharged, And the emergency lighting does not come on from the next time. If there is an emergency lighting such as over-current, connection failure of connected lamp load, abnormal condition of load, etc., The stability of the apparatus can not be secured, and in particular, the conventional emergency power source apparatus Only lamp load lights to be simply an emergency, the economic loss should the general lighting in the intensity of the lamp decreases mainly used for emergency purposes only induce people, there is no general lighting function separately.

In addition, the general lighting is provided by a separate facility, and the power supply of the interphone for emergency communication is not provided, so that it is not actively prevented from various safety accidents.

In addition, since there is no abnormality detection function such as an overcurrent detection function, a short circuit of a lamp load, and a socket connection failure during an emergency lighting, the circuit protection and the protection of the lamp load can not be stably performed, Even if a power failure occurs, the lamp load is turned on when no illumination is required, thereby wasting unnecessary power, damaging the battery, and causing economic loss.

A prior art related to the present invention is Korea Unexamined Patent Publication No. 10-2010-0126873 (2010.12.03).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an emergency switching relay device for an illumination lamp of the present invention will be described with reference to the accompanying drawings.

2 is a block diagram showing a configuration of an emergency switching relay apparatus for an illumination lamp according to the present invention. FIG. 3 is a block diagram showing the configuration of the emergency switching relay apparatus for an illumination lamp of the present invention, Fig.

Referring to Figs. 1 to 3, the emergency switching relay apparatus for an illumination lamp of the present invention includes a case 10.

The first and second emergency power supply lines 210 and 220 and the first and second constant power supply lines 110 and 120 are connected to one side of the case 10 and the first and second output ends 310 and 320 A pair of output lines (not shown) protruding from the output lines.

Referring to FIGS. 2 and 3, the emergency relay device for an illumination lamp of the present invention includes a normal power supply unit 100, an output power supply unit 300, an emergency power supply unit 200, and an emergency control module 400 .

The emergency control module 400 includes an abnormality determination sensor 410, a switch 420, and a controller 430, which are embedded in the case 10 and determine whether the output power is abnormal do.

The output power unit 300 has first and second output terminals 310 and 320.

The normal power supply unit 100 has first and second constant power supply lines 110 and 120 and the emergency power supply unit 200 has first and second emergency power supply lines 210 and 220.

The switch 420 includes first and second switches 421 and 422.

The first switch 421 selectively connects one of the first emergency power supply line 210 and the first constant power supply line 110 to the first output terminal 310.

The second switch 422 selectively connects either the second emergency power supply line 220 or the second constant power supply line 120 to the second output terminal 320.

The controller 430 controls the abnormal power supply unit 200 and the output power supply unit 300 to electrically connect the emergency power supply unit 200 and the output power supply unit 300 using the switch 420, .

Therefore, the emergency control module 400 controls the emergency power supply unit 200 to supply the emergency power to the output power supply unit 300 when the normal power supply fails, do.

In addition, the abnormality determination sensor 410 determines that the power source is abnormal when the constant power source is less than or equal to the preset reference power source.

At the same time, the abnormality determination sensor 410 determines whether or not the abnormality has occurred in the constant power source.

For example, the abnormality determination sensor 410 determines whether the constant power source is below or equal to the preset reference power source, and transmits the result to the controller 430.

The controller 430 cuts off the power from the constant power supply 100 and disconnects the emergency power from the output power supply 400 from the emergency power supply 200. In the case where the normal power is less than or equal to the reference power supply, (300).

That is, the first switch 421 connects the first emergency power supply line 210 to the first output terminal 310 and the second switch 422 connects the second emergency power supply line 220 to the second output terminal 320, .

Accordingly, the emergency power source from the emergency power source unit 200 can be applied to the output power source unit 300.

At the same time, the first and second power supply lines 110 and 120 may be shorted to the first and second output ends 310 and 320.

According to the configuration and operation of the present invention, in the embodiment according to the present invention, a relay is provided on the emergency power source side, and when an abnormality occurs in the constant power source, the emergency power source can be used as the output power source.
