The utility model content
In order to overcome the deficiency of prior art, the utility model provides a kind of LED lamp that has battery, be intended to when civil power breaks down, the LED lamp can also operate as normal.
In order to achieve the above object, the technical scheme that the utility model adopted is following:
A kind of LED lamp that has battery, it comprises battery, first testing circuit, second testing circuit, control circuit, automatic transfer switch, power circuit and led light source; First testing circuit, automatic transfer switch electrically connect with civil power respectively; First testing circuit also electrically connects through the control circuit and second testing circuit; Second testing circuit and battery electrically connect; Automatic transfer switch also electrically connects with power circuit, and power circuit and led light source electrically connect.
Said first testing circuit is used for detecting in real time the duty of civil power, and the signal of telecommunication of civil power duty is transferred to control circuit; Said second testing circuit is used for detecting in real time the duty of battery, and the signal of telecommunication of battery-operated state is transferred to control circuit;
Said control circuit receives the civil power duty signal of telecommunication and the battery-operated state signal of telecommunication from first testing circuit, second testing circuit, and transmits control signal to automatic transfer switch; When municipal power failure, control automatic transfer switch and battery are connected, and battery is that power circuit provides operating voltage; Power circuit is that led light source provides operating voltage; Thereby guarantee the operate as normal of led light source, when the civil power operate as normal, when second testing circuit detects the accumulator electric-quantity deficiency; Civil power is connected through first testing circuit, control circuit, second testing circuit and battery; Civil power is a charge in batteries, and it is full that second testing circuit detects accumulator electric-quantity, and control circuit disconnection civil power is connected with battery.
As preferably, said automatic transfer switch is used for when the civil power operate as normal, and power circuit and civil power are connected, and is the power circuit power supply by civil power, guarantees the led light source operate as normal; When municipal power failure, the disconnection of control circuit control automatic transfer switch is connected with civil power, and connects with battery, is the power circuit power supply through battery.
Said power circuit is the led light source power supply circuits.
As preferably, said led light source can be LED bulb lamp or LED lamp affixed to the ceiling or LED spot or LED flat lamp or the high well lamp of LED or LED street lamp or LED desk lamp etc.
The LED lamp that has battery is when preventing the civil power irregular working, can't give the power supply of LED lamp, the inconvenience that causes people to live and work.When particularly meeting accident, during like earthquake, mains-supplied equipment fault, cause power supply normally to carry out.In such cases, the automatic transfer switch automatic disconnection is connected with civil power, is communicated with battery; By battery is the power circuit power supply; Thereby make LED lamp operate as normal, light fixture still can be under the situation of civil power outage operate as normal, for people's operate as normal and life facilitate.And overcome existing light fixture as a kind of lighting that uses LED to make light source and had shortcomings such as power consumption efficiency is low, service life is short, cost is high, not environmental protection.
Compared with prior art, the beneficial effect of the utility model is: the LED lamp can be when municipal power failure, guarantees people's operate as normal and life through battery for the power supply of LED lamp, and long service life, use cost are low.In addition, the utility model also has advantages such as the energy of saving, brightness height, environmental protection.The LED lamp of the utility model can be used for lighting spaces such as family, school, office, retail shop, warehouse, workshop, data center, station and mine.
The specific embodiment
As shown in Figure 1, a kind of LED lamp that has battery, it comprises battery 5, first testing circuit 2, second testing circuit 4, control circuit 3, automatic transfer switch 6, power circuit 7 and led light source 8.
First testing circuit 2, automatic transfer switch 6 electrically connect with civil power 1 respectively; First testing circuit 2 also electrically connects through the control circuit 3 and second testing circuit 4; Second testing circuit 4 electrically connects with battery 5; Automatic transfer switch 6 also electrically connects with power circuit 7, and power circuit 7 electrically connects with led light source 8.
Said first testing circuit 2 is used for detecting in real time the duty of civil power 1, and the signal of telecommunication of civil power 1 duty is transferred to control circuit 3; Said second testing circuit 4 is used for detecting in real time the duty of battery 5, and the signal of telecommunication of battery 5 duties is transferred to control circuit 3.
Said control circuit 3 receives the civil power 1 duty signal of telecommunication and the battery 5 duty signals of telecommunication from first testing circuit 2, second testing circuit 4, and transmits control signal the on off operating mode of control automatic transfer switch 6 to automatic transfer switch 6.When civil power 1 broke down, control automatic transfer switch 6 was connected with battery 5, and battery 5 provides operating voltage for power circuit 7; Power circuit 7 provides operating voltage for led light source 8; Thereby guarantee the operate as normal of led light source 8, when civil power 1 operate as normal, when second testing circuit 4 detects battery 5 electric weight deficiency; Civil power 1 is connected with battery 5 through first testing circuit 2, control circuit 3, second testing circuit 4; Civil power 1 is battery 5 chargings, and it is full that second testing circuit 4 detects battery 5 electric weight, and control circuit 3 disconnection civil powers 1 are connected with battery 5.
Said automatic transfer switch 6 is used for when civil power 1 operate as normal, and power circuit 7 and civil power 1 are connected, and is power circuit 7 power supplies by civil power 1, guarantees led light source 8 operate as normal; When civil power 1 fault, 6 disconnections of control circuit 3 control automatic transfer switch are connected with civil power 1, and connect with battery 5, are power circuit 7 power supplies through battery 5.
Said power circuit 7 is the circuit for led light source 8 power supplies.
The led light source 8 of present embodiment can adopt LED bulb lamp, LED lamp affixed to the ceiling, LED spot, LED flat lamp, the high well lamp of LED, LED street lamp, LED desk lamp etc.
Above-mentioned embodiment is merely the preferred implementation of the utility model; Can not regard the restriction to the utility model protection domain as, the change of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement all belong in the protection domain of the utility model.
