Embodiment Construction
[0026] The following are specific embodiments of the present invention, and further illustrate the technical solutions of the present invention in conjunction with the accompanying drawings, but are not limited to these embodiments.
[0027] Such as figure 1 As shown, the battery-powered lighting controller that lives within its means includes a battery 1 , an LED lamp 2 , a control unit ECU 3 , a voltage detection circuit 4 , a charging current detection circuit 5 , a load current detection circuit 6 , and a control circuit 7 .
[0028] Specifically, the anode of battery 1 is connected to the cathode of one-way diode D1, and the anode of one-way diode D1 is connected to charging anode S+. The function of one-way diode D1 is to prevent backflow when the input voltage is lower than the voltage of battery 1. The negative pole of the storage battery 1 is grounded, and the charging negative pole S- is set at the sampling point SP1.
[0029] The anode of the LED lamp 2 is connecte...
