Consume larger, integrally need about 45mA；If the control signal of the transmission of Digiplex 52 is not received in later one minute again
When, the radio receiving transmitting module 16 enters the park mode of low-power consumption.But it is to be able to wake up the radio receiving transmitting module 16,
The main control module 11 can be with the periodic activation radio receiving transmitting module 16 of 8 seconds, then open circuit loss can be big with the cycle change of 8 seconds.Such as
When fruit radio receiving transmitting module 16 enters park mode, most it is long need can to realize again for 8 seconds controller for solar 10 with it is wireless
Data interaction between remote control 52.In addition, user can also send dormancy directly by the dormancy button of Digiplex 52
Signal enters Low-power-consumptiodormancy dormancy pattern to controller for solar 10, the controller for solar 10 according to sleep signal.
As shown in figure 9, the present invention provides the preferred embodiment of LED load protection.
Specifically, the controller for solar 10 includes voltage increase and current constant module 1111, and the load equipment 40 is born for LED
Carry；Wherein, the voltage that the voltage increase and current constant module 1111 exports to the lithium battery group 30 carries out voltage increase and current constant operation, and will carry out
Voltage increase and current constant operation after voltage output to LED load, if the controller for solar 10 detect LED load be over-current state or
During person's overvoltage condition, the controller for solar 10 control LED load is stopped.
The mode of the open-circuit-protection of load equipment 40 presented below：The load end of the controller for solar 10 does not meet LED
During load, the maximum output voltage that load end allows is 60V, and when detecting load voltage more than 60V, meeting is the pass of load equipment 40
Close, load indicator lamp slow flash, can be reattempted to after 10 seconds and open load equipment 40.
The mode of the short-circuit protection of load equipment 40 presented below：During the load terminal shortcircuit of the controller for solar 10, lead to
Over-sampling load current exceedes the short circuit current protection set, can close load equipment 40, indicator lamp quick flashing is loaded, by 1 point
Zhong Houhui, which is reattempted to, opens load equipment 40, if short circuit releases, controller for solar 10 can recover to export.
Wherein, the controller for solar 10 is voltage increase and current constant source, when the lamp string voltage that LED load connects is less than or close to defeated
When entering voltage, although the boosting regulation dutycycle of controller for solar 10 is reduced to zero, but output current can't arrive target current,
Cause output current very big, LED may be burnt out for a long time by not protecting.It is presented below to judge load equipment 40 for the two of overcurrent condition
Kind mode：
If mode one, remote control 50 set electric current be less than 300mA, when detection load current be more than setting electric current+
During 50mA, it is judged as excessively stream；
If the electric current that mode two, remote control 50 are set is more than or equal to 300mA, electric current is set when the load current of detection is more than
20% when, be judged as excessively stream；
After load equipment 40 is judged for overcurrent condition, controller for solar 10 closes load equipment 40, loads indicator lamp
Quick flashing, it can be reattempted to after 1 minute and open load equipment 40, if excessively stream releases, controller for solar 10 can recover defeated
Go out.
