Brief description of the drawings
Fig. 1 is the module diagram of fire-fighting emergent LED drive circuit in the application preferred embodiment.
Specific embodiment
In order that the application technical problem, technical scheme and beneficial effect to be solved becomes more apparent, below in conjunction with
Drawings and Examples, are further elaborated to the application.It should be appreciated that specific embodiment described herein is only used
To explain the application, it is not used to limit the application.
Fig. 1 is referred to, the fire-fighting emergent LED drive circuit of various LED lamps is applied in the application preferred embodiment, its
For driving LED 10.Fire-fighting emergent LED drive circuit includes controlling switch S1, isolation constant-current drive circuit 11, standby charging
Circuit 12, battery 13, booster circuit 14 and single-chip microcomputer 15.
Isolate the input of constant-current drive circuit 11 by controlling switch S1 incoming transport power supply AC, output termination LED
10；The input incoming transport power supply AC of standby charging circuit 12, output termination battery 13；Booster circuit 14 is connected to electric power storage
Between pond 13 and LED 10；Single-chip microcomputer 15 is connected with constant-current drive circuit 11, standby charging circuit 12 and battery 13 is isolated,
Single-chip microcomputer 15 controls standby charging circuit 12 for whether battery 13 charges according to the electricity of battery 13, according to AC power AC's
Whether state control booster circuit 14 starts as LED 10 is powered.The voltage of AC power AC be zero (disconnecting) or less than threshold
Start booster circuit 14 during value for LED 10 is powered.
In the present embodiment, isolation constant-current drive circuit 11 is the constant-current driven chip with control interface.Can be according to LED 10
Different capacity select different chips, such as：T6335A or Texas Instrument TPS61059 of the brilliant science and technology of platform etc..Booster circuit 14 is
BUCK circuits.Battery 13 is 12V lithium battery groups.Standby charging circuit 12 is battery charging chip, can be according to battery pack
