Embodiment

[0023] Embodiment: A method for controlling solar LED lamps powered by mains electricity, which is provided with a battery residual power threshold Wh. When the remaining battery power is less than Wh, if it is daytime, the mains power supply circuit and the solar power supply circuit will charge the battery together. If At night, the mains power supply circuit and the battery supply power together. When the remaining power of the battery is greater than or equal to Wh, if it is in the daytime, the mains power supply circuit stops working. When the battery is not fully charged, the solar power supply circuit alone charges the battery. At night, the mains power supply circuit stops working, and the battery supplies power alone.

[0024] In this embodiment, the threshold value Wh of the remaining electric energy of the battery is set according to the actual electric energy demand consumed by the solar LED lamp in one night, and it only needs to meet the following conditions: when...

Abstract

The invention discloses a control method and circuit for a solar LED lamp with supplementary power supply by mains supply, a storage battery residual electric energy threshold value Wh is set, when the storage battery residual electric energy is smaller than Wh, a mains supply circuit and a solar power supply circuit charge the storage battery together in the daytime, and the mains supply circuit and the storage battery supply power together in the night. When the residual electric quantity of the storage battery is greater than or equal to Wh, the mains power supply circuit stops working in the daytime, the solar power supply circuit independently charges the storage battery when the storage battery is not fully charged, and the mains power supply circuit stops working at night, and the storage battery independently supplies power; the control method and circuit have the advantages that the maximum power of mains power supply can be reduced, the wire diameter requirement of a power supply wire is reduced, the cost of the power supply wire can be reduced, and the installation cost of the solar LED lamp with commercial power supplementary power supply is reduced.

Description

technical field [0001] The invention relates to a solar LED lamp, in particular to a control method and circuit for a solar LED lamp supplemented by commercial electricity. Background technique [0002] Solar energy is a kind of clean energy, and the use of solar energy for power generation has been widely used in many industries, and it is showing a trend of continuous expansion. In the field of LED lamp design, there have been solar LED lamps powered by solar energy. The existing solar LED lights are usually equipped with a battery and a solar power supply circuit. Turn off the light during the day. If the battery is not fully charged at this time, the solar power supply circuit converts sunlight into electrical energy and stores it in the battery to charge the battery. If the battery If it is fully charged, stop charging. At night, the lights are automatically turned on, and the solar LED lights are driven by the electric energy stored in the battery to emit light. Whe...
