Abstract
The utility model discloses a LED panel lamp emergency power supply device. The device comprises a charging driving circuit, a rechargeable battery pack, a current relay and a current relay driving circuit. The structure of the device of the utility model is simple. The current relay is addedly arranged between a panel lamp driver and a panel lamp. The current relay is used to realize switching between normal power supply and emergency power supply. When the normal power supply is performed, the current relay is connected with an original driver of the panel lamp so as to directly lighten the LED panel lamp and meanwhile a normal power supply system carries out charging on the battery pack simultaneously. When the normal power supply is failed, the current relay disconnects the original driver and switches to an emergency power supply device driving mode. At this time, the battery pack provides power for the LED panel lamp so as to lighten the LED panel lamp. An emergency illumination function of the LED panel lamp is realized.
Description
Technical field
The utility model relates to the emergency power supply field, relates in particular to a kind of LED Panel light emergency power supply unit.
Background technology
The LED lighting technology is the important content of present world lighting field develop rapidly, and the LED lighting technology substitutes the trend of common fluorescent lamp and also day by day strengthens.Wherein the use of LED Panel light in office and commercial lighting is also more and more extensive.Therefore, at some special occasions such as hospital, subways, the illumination between the LED Panel light needs not.At special occasions, in order to tackle such burst thing, all be to prepare emergency power supply, but emergency power supply mostly is greatly the master control type emergency power supplies such as generator, and this large-scale emergency power supply the time spent all need not safeguard at ordinary times, and the dynamics of safeguarding etc. are all by attendant's professional ethics, if and the attendant fails regularly, in time safeguard or during the burst outage, emergency power plant can't start, then can't continue illumination, and in the place such as the flows of the people such as hospital, subway are large, the event such as be easy to generate a panic, trample, thus unnecessary loss caused.
The utility model content
The purpose of this utility model provide the purpose of this utility model provide a kind ofly react fast, LED Panel light emergency power supply unit that cost is low, in the time of can working as the normal power supply thrashing of LED Panel light, directly the driving LED Panel light is emergent lights illumination for the backup battery group.
The utility model adopts following technical proposals:
A kind of LED Panel light emergency power supply unit, comprise the charging drive circuit, rechargeable battery pack, current relay and current relay drive circuit, one end of described charging drive circuit connects the mains electricity input end, the other end connects rechargeable battery pack, the other end of rechargeable battery pack connects current relay by the current relay drive circuit, the output of current relay is used for connecting LED Panel light drive circuit, described LED Panel light drive circuit one end connects the LED Panel light by the coil of current relay, and the LED Panel light drive circuit other end connects the input of LED civil power by the normally opened contact of current relay.
Described relay is current relay.
The utility model is simple in structure, installs current relay additional between Panel light driving and Panel light, is realized the conversion between normal power supply and the emergency service by current relay.When normal power supply, current relay connects the logical original driver of Panel light and directly lights the LED Panel light, and this moment, the normal power supply system charged to battery pack simultaneously; When normal power supply lost efficacy, current relay disconnected original driving and is transformed into the emergency power supply unit drive pattern, and to the power supply of LED Panel light, light the LED Panel light by battery pack this moment.Make the LED Panel light be not limited to general lighting, realized the function of emergency illumination of LED Panel light.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of LED Panel light emergency power supply unit, comprise the charging drive circuit, rechargeable battery pack, current relay and current relay drive circuit, one end of described charging drive circuit connects the mains electricity input end, the other end connects rechargeable battery pack, the other end of rechargeable battery pack connects current relay by the current relay drive circuit, the output of current relay is used for connecting LED Panel light drive circuit, described LED Panel light drive circuit one end connects the LED Panel light by the coil of current relay, and the LED Panel light drive circuit other end connects the input of LED civil power by the normally opened contact K1 of current relay.Described relay is current relay.
During installation, with current relay and drive circuit, charging drive circuit, be combined into an integral body, form complete LED Panel light emergency power supply unit after mixing rechargeable battery set.Add current relay between the drive circuit of original LED Panel light and Panel light, wherein the normally opened contact K1 of current relay is arranged on on-off action between the drive circuit of LED Panel light and the civil power.
In the course of work, when dispatch from foreign news agency is powered when normal, the utility model receives the driving control of charging drive circuit, real-time current relay normally open contact K1 action, after the current relay normally opened contact K1 closure, civil power joins by LED Panel light driver and Panel light input.This moment, the operating power switch can realize lighting or cutting out of LED Panel light.Simultaneously, outside civil power charges to battery pack by the charging drive circuit;
When mains supply has a power failure, current relay coil dead electricity in the LED Panel light emergency power supply unit, current relay normally opened contact K1 automatically replies initial condition, it is open mode, this moment, LED Panel light driver and being connected of Panel light were transformed into the emergency driving of emergency power supply unit and the input of Panel light is joined, and automatically lighted the LED Panel light.At this moment, what Panel light switch originally can not the control panel lamp lighting or closing, until after battery electric quantity exhausted, the emergency power supply unit protectiveness was closed the LED Panel light; In the process of emergency service, when again powering, emergency power supply unit joins LED Panel light driver and Panel light input automatically by current relay, again rechargeable battery pack is charged simultaneously.
The utility model is according to the requirement of principle and the emergency lighting standard of LED Panel light, the output voltage of emergency power supply unit and LED Panel light be complementary (being generally 12V, 24V, 36V), electric current can be adjusted to 20%～100% of normal power according to the illumination requirement of user when emergent, can reduce as required like this power consumption when meeting an urgent need, thereby prolong the crash time.According to the instructions for use of different occasions, the general crash time was designed to 90,120,180 minutes etc.
