Abstract

The invention relates to a solar light control switch circuit, belonging to the technical field of electronic circuits. The solar light control switch circuit comprises a photovoltaic cell (E1), a triode (VT), an adjustable resistor (R), a power supply (E2), a switch (S), a relay (K) and an illuminating lamp (H). The positive electrode of the photovoltaic cell (E1) is connected with the base electrode of the photovoltaic cell (E1). The emitting electrode of the triode (VT) is connected with one end of the adjustable resistor (R) and the negative electrode of the power supply (E2). The solar light control switch circuit is scientific and reasonable in design, can enable the lawn lamp to automatically turn on and off according to the change of the strength of sunlight, can save energy greatly and is easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a solar light control switch circuit. Background technique [0002] At present, many residents or citizen squares have lawn lights on lawns, green spaces and other places, which are not only used for night lighting, but also beautify the environment. However, the switch of the current lawn lamp is not automated, and someone must control the switch, and sometimes it will be on during the day, which greatly wastes energy. Contents of the invention [0003] The object of the present invention is to provide a solar light control switch circuit, which can automatically turn on and off the lawn lamp by utilizing the change of the intensity of sunlight, which greatly saves energy. [0004] In order to solve the existing problems of the background technology, the present invention adopts the following technical scheme: it is made up of photocell E1, triode VT, adjustable r...
