Abstract

The utility model relates to an EPS emergency lamp with a transfer switch, comprising a lamp one circuit of which is connected with commercial power through the transfer switch while the other circuit thereof is connected with a standby power supply EPS through a relay. The utility model has simple wire layout which is the same as that of an ordinary lighting lamp; as the transfer switch of the lamp is able to be arranged inside the lamp or integrally arranged with a control switch, the transfer switch can be flexibly arranged to the need of an emergency lighting point; the EPS emergency lamp with a transfer switch adopts the principle of emergency priority and is able to instantly turn on regardless of the state of the commercial power as long as the standby power supply EPS switches on.

Description

The EPS emergency luminaire that has change-over switch

Technical field

The utility model relates to a kind of emergency luminaire, refers in particular to a kind of EPS emergency luminaire that has change-over switch.

Background technology

NFA rules and regulations skyscraper, large public building adopts and supplies power with double circuit, and wherein one the tunnel is generally back-up source EPS fire-fighting emergency power supply.Skyscraper, emergency lighting must be adopted in public domains such as large public building corridor, lift port, and routine is thrown light on and be emergency lighting integrated is industry development trend.

Existing emergency luminaire is generally by city's electric control switch, and the problem of existence is the switching of must meeting an urgent need simultaneously of the light fixture of whole piece circuit, can not arrange the emergency lighting point on demand.Need simultaneously just can make light fixture enter the emergency lighting state after the civil power outage.

Summary of the invention

The utility model provides a kind of EPS emergency luminaire simple, that can shorten the band change-over switch of wiring distance, economical with materials cost that connects up.

A kind of EPS emergency luminaire that has change-over switch comprises light fixture, and described light fixture switches switch one road by one and inserts civil power, and back-up source EPS is inserted through relay in another road.

Have access to reduction voltage circuit and filter circuit between described relay and the back-up source EPS.

In the building that is equipped with back-up source EPS, change-over switch can directly be contained in common Down lamp, lamp affixed to the ceiling, and Grille lamp, or use as emergency luminaire in the Frame lamp.

After the civil power outage, the change-over switch of light fixture automaticallyes switch and inserts back-up source EPS, be enabled as the light fixture power supply by back-up source EPS, make emergency luminaire keep normal bright state, not influenced by switch,, need not electric control switch by the city because reserve emergency power supply line can be directly connected to emergency luminaire, thereby shortened wiring distance, saved material cost.

The utility model wiring is simple, and is identical with the ordinary luminaire wiring.Because the change-over switch of light fixture can be installed in the light fixture or with the gauge tap one and install, so can be according to the needs flexible arrangement of emergency lighting point.The EPS emergency luminaire that has change-over switch adopts emergent preferential principle, the back-up source EPS power supply no matter what state civil power is operated in, and the EPS emergency luminaire that has change-over switch is lighted the influence that is not subjected to city's electricity condition immediately.

Description of drawings

Fig. 1 is an electrical block diagram of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of EPS emergency luminaire that has change-over switch comprises light fixture D, and light fixture D switches switch one road by one and inserts civil power L, and back-up source EPS is inserted through relay J in another road.

Have access to the reduction voltage circuit that composes in parallel by a resistance R and a capacitor C 1 between relay J and the back-up source EPS, and the filter circuit of forming by a bridge rectifier D1-D4 and a capacitor C 2.

When normal condition, civil power live wire L is connected with light fixture D by the relay J normally-closed contact, by K switch control light fixture D light on and off.When emergency rating took place in the civil power outage, back-up source EPS entered the emergency service state, drove the relay J adhesive by reduction voltage circuit and filter circuit output low-voltage dc power supply, and light fixture D power supply transfers back-up source EPS power supply to.At this moment, light fixture D lights, and controlled by any switch, keeps Chang Liang.After treating that emergency rating is removed, back-up source EPS withdraws from power supply, and light fixture D recovers controllable state.

Claims

1. an EPS emergency luminaire that has change-over switch comprises light fixture (D), it is characterized in that: described light fixture (D) switches switch one road by one and inserts civil power (L), and back-up source EPS is inserted through relay (J) in another road.

2. the EPS emergency luminaire that has change-over switch as claimed in claim 1 is characterized in that: have access to reduction voltage circuit and filter circuit between described relay (J) and the back-up source EPS.
