Abstract
The present utility model discloses an LED fluorescent lamp emergency power supply. The power supply is characterized in that the power supply comprises a battery group, a charger, an inverter, a controller, a voltage detection circuit and a contactor; the battery group is connected with the commercial power through the charger, the battery group is connected with the LED fluorescent lamp through the inverter, and a normally closed switch of the contactor is connected in series between the commercial power and the LED fluorescent lamp; the inverter is controlled by the controller, and the voltage detection circuit and a coil of the contactor are all connected with the controller. The LED fluorescent lamp emergency power supply can be used for providing stable and lasting emergency electric energy for an LED fluorescent lamp.
Description
Technical field
The utility model relates to a kind of LED fluorescent lamp emergency power supply, and the utility model is applicable to 20W does emergency lighting with interior LED fluorescent lamp.
Background technology
The LED fluorescent lamp in case have a power failure, then can't provide illumination in use, therefore, in public arenas such as hospitals, needs the situation of emergency light very general, therefore is necessary to design a kind of LED fluorescent lamp emergency power supply.
The utility model content
The utility model technical problem to be solved provides a kind of new LED fluorescent lamp emergency power supply, and this LED fluorescent lamp emergency power supply can provide the emergency power of stable and durable for the LED fluorescent lamp.
The technical solution of utility model is following:
A kind of LED fluorescent lamp emergency power supply comprises battery pack, charger, inverter, controller, voltage detecting circuit and contactor; Battery pack is electrically connected with the city through charger, and battery pack is connected with the LED fluorescent lamp through inverter, is serially connected with the normally closed switch of contactor between civil power and the LED fluorescent lamp;
Inverter is controlled by controller, and voltage detecting circuit all is connected with controller with the coil of contactor.
Described controller is PLC, dsp processor or single-chip microcomputer.
Beneficial effect:

Description of drawings
Fig. 1 is the structured flowchart of the LED fluorescent lamp emergency power supply of the utility model.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
Embodiment 1:
As shown in Figure 1, a kind of LED fluorescent lamp emergency power supply is characterized in that, comprises battery pack, charger, inverter, controller, voltage detecting circuit and contactor; Battery pack is electrically connected with the city through charger, and battery pack is connected with the LED fluorescent lamp through inverter, is serially connected with the normally closed switch of contactor between civil power and the LED fluorescent lamp;
Inverter is controlled by controller, and voltage detecting circuit all is connected with controller with the coil of contactor.
Described controller is PLC, dsp processor or single-chip microcomputer.
Course of work explanation:
During the civil power regular supply, battery pack be in the charging stand-by state; When meeting with accident such as earthquake, attack, blast or other emergency and cause civil power and interrupt suddenly that perhaps fluctuating range is big; Controller detects fault through voltage detecting circuit (prior art) and exists; Make the coil electricity of contactor, the normally closed switch KM1 of contactor opens, and cuts off getting in touch of LED fluorescent lamp and civil power; And control inverter is alternating current for the LED fluorescent lamp continues power supply with the electric energy inversion in the battery pack, guarantees lamp lighting and safety.After battery charge is saturated, gets into automatically and safeguard state of charge, compensation self discharge, the performance of battery maintenance and useful life.The battery of coupling different capabilities can reach 1-5 hour Emergency Light time, adapts to the needs of different occasions.
