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...

Abstract

The invention provides a storage-battery-powered lighting controller capable of making ends meet, belonging to the technical field of street lamp lighting controllers and solving the problem that the traditional street lamp system powered by the storage battery cannot ensure long-time lighting every day. The lighting controller comprises an LED (light-emitting diode) lamp and a storage battery, wherein the anode of the LED lamp is connected with the positive electrode of the storage battery; the cathode of the LED lamp is connected with a control circuit; and the control circuit is connected with the negative electrode of the storage battery to form a circuit for supplying electric power to the LED. The controller also comprises a voltage detection circuit, a charge current detection circuit and a control unit ECU (electronic control unit), wherein the control unit ECU is used for reading the charge current to calculate the allowable current at the current day, and adjusting the load current of the LED lamp to be the allowable current through the control circuit while detecting that the voltage of the storage battery is lower than the set voltage of the control unit ECU. The controller has the advantages that: a manner of making ends meet is adopted, thus the street lamp system adopting the controller can light for long time every day in spite of long-time overcast and rainy and windless weather.

Description

technical field [0001] The invention belongs to the technical field of wind-solar complementary street lamps, and relates to a lighting controller powered by a storage battery, in particular to a controller that supplies lighting according to the energy stored in the storage battery in a manner that pays what you pay. Background technique [0002] Public lighting systems such as street lights, landscape lights, and lawn lights are indispensable public facilities in urban areas. Traditional street lamps and landscape lamps are powered by mains electricity. In addition to lamps and light poles, pipelines, cables, power supply control cabinets, etc. need to be buried. The workload is heavy, the cost is high, and a large amount of electric energy is consumed all year round . With the development of technology, the cost price of wind energy, solar energy and wind-solar complementary street lighting systems has been equal to or even slightly lower than that of traditional street ...
