(1) Photosensitive sensor. Solar lawn lamps need light control switches, designers often use photosensitive resistance to automatically switch lights, in fact, the solar cell itself is an excellent photosensitive sensor, using it as a photosensitive switch, better than the photosensitive resistance. For the only use of a 1.2VNi Cd battery solar lawn lamp, the solar cell components are composed of four solar cells in series, the voltage is low, the voltage under the weak light is lower, and the sky has no black voltage below 0.7V, which causes the optical control switch to fail. In this case, only one transistor coupled with direct amplification can solve the problem. It
(2) control the load according to the battery voltage. Solar lawn lamps often require continuous rainy days to maintain, which will increase the cost of the system. We can reduce the cost of the system by reducing the number of LED access, or reducing the daily luminescence time of the solar lawn lamp, when the voltage of continuous rain storage battery is reduced.
