The invention provides a device for lighting a solar lawn. The device comprises a solar cell plate, a storage cell and a lawn light; and in addition, the device also comprises a control device, wherein the control device is formed by a core chip. In the device, because all control circuits are integrated in an integrate circuit chip, so that the defects of big energy consumption, big material loss, poor water resistance and the like due to discrete elements are overcome, and simultaneously, the chip is additionally provided with an overcharge protection module which is used for avoiding the overcharge circuit of the storage cell, so that the electrically charging safety of the storage cell is ensured.
Description
A solar lawn lighting device technical field The invention relates to a lawn lighting device, in particular to a lawn lighting system which uses solar cells to provide electric energy for LED lamps of the lawn lamp, and the system has a controller. Background technique The current solar lawn lighting device in the industry is shown in Figure 1. It mainly includes solar panels that collect solar energy during the day, batteries that store the electric energy generated by the aforementioned solar panels, and lawn lamps. Now lawn lamps are mostly composed of LED lamps. The lawn lamp is powered by a battery to illuminate the lawn. In this way, the lawn lighting system uses solar energy to provide electricity for the lawn lamp, which is a kind of green energy. Its working process is to charge the battery through the solar panel during the day. When night falls, the solar battery cannot generate electricity. The battery powers the lawn lights. The control circuit of the solar ...
