Description

Technical Field

[0001] The invention relates to the technical field of solar lamp circuits, in particular to a circuit structure which can increase the standby days of a solar lamp and can automatically power on. Background Art

[0002] Solar lamps use solar energy to generate electricity and do not need to use traditional coal, oil or other fossil fuels. Therefore, they will not produce carbon dioxide and other harmful substances, which meets environmental protection requirements. At the same time, it does not consume power from the power grid and can greatly reduce electricity bills. Solar lamps do not require power lines and only need to be installed where the sun can shine, so the installation is very convenient and users do not need to worry about wire obstruction. In addition, solar lamps have no mechanical parts that require maintenance and only require regular cleaning and battery status inspection. Solar lamps can generally be used for more than five years and do not require frequent battery replacement and maintenance. Therefore, they are more economical and practical. The operation and maintenance costs of solar lamps are low. Except for a small amount of electricity bill that needs to be converted to mains power on rainy days, the operating cost is almost zero. The entire system is automatically controlled and no human intervention is required.

[0003] Solar lamps use LiFePO4, lithium iron phosphate batteries as energy storage media. During the day, solar photovoltaic panels are used as energy to charge and store the battery pack, and at night, the electricity in the battery is discharged to automatically turn on the light. Charging or discharging is controlled by the solar controller for MPPT or PWM. The controller will be equipped with a functional module, 2.4G Bluetooth communication or radar microwave sensing, infrared human body sensing and other functional modules. When these modules are combined together, the static power consumption is 0.2-0.5W. With a 25.6V30AH=768WH battery and a static power consumption of 0.2W, the standby time is: 768WH / 0.2W=3840H=160 days;

[0004] However, the traditional solar lamp circuit has the following disadvantages:

[0005] After long-term sea or land transportation, the battery pack is basically depleted when it reaches the customer, and the lamp can no longer be lit for testing, which deteriorates the customer's experience. The industry's usual practice is to lead the solar control panel to an external switch through a lead wire to cut off and turn on the power, or through a magnetic switch. Both require human intervention to cut off and turn on the power to make the solar controller work. The specific operation of the lead wire method is to manually cut off the red wire to disconnect the circuit, and manually short-circuit it during operation; the specific operation of the magnetic switch method is to manually remove the magnet to power on the circuit. Summary of the invention

[0006] The purpose of the present invention is to provide a circuit structure that increases the standby days of solar lamps and can automatically power on, so as to solve the problem mentioned in the above background technology that the battery pack is basically exhausted when it arrives at the customer after long-term sea or land transportation, and the lamp can no longer be lit for testing, which deteriorates the customer's experience; the usual practice in the industry is to lead the solar control panel to an external switch through a lead wire to cut off and turn on the power or to cut off and turn on the power through a magnetic switch, both of which require human intervention to cut off and turn on the power to make the solar controller work, and the specific operation of cutting off and turning on the power of the lead wire method is to manually cut off the red line to disconnect the circuit and manually short-circuit it during operation; the specific operation of cutting off and turning on the power of the magnetic switch is to manually disassemble the magnet to power on the circuit.
