Abstract

The invention relates to an intelligent solar lawn lamp. During the daytime, the resistance value of a photoresistor Rt is low, a triode BG2 is turned off, a relay J2 loses power, the normally-open contact of the relay J2 is turned off and the light emitting diodes LED1-LED12 are not lit. At night, the resistance of the photoresistor Rt increases, the triode BG2 is turned on, the relay J2 is energized, the normally-open contact of the relay J2 is closed and the light emitting diodes LED1-LED12 are all lit. When the working voltage of a solar cell PV is low, a triode BG1 is turned off and a relay J1 loses power, and a storage battery E supplies power to the lawn lamp. The solar cell is applied to supply power so that the solar energy resource can be utilized to the maximum extent, the cableis not need to be laid, the safety problem of the cable after long-term use is not need to be considered and the occurrence of safety accidents is reduced; besides, the solar lawn lamp can be automatically extinguished at daybreak and automatically lit at dark.

Description

technical field [0001] The invention relates to a lawn lamp, in particular to an intelligent solar lawn lamp, which belongs to the technical field of lighting. Background technique [0002] The lawn lamp adds safety and beauty to the urban green landscape with its beautiful appearance and soft lights, and generally has the characteristics of easy installation and strong decoration. It can be used for green belts in parks, garden villas, square greening, etc. sex lighting. [0003] At present, many lawn lights are powered by mains electricity, and long cables need to be laid. After a long time of use, the cables are prone to leakage and cause unsafe factors. Contents of the invention [0004] Aiming at the problems existing in the above-mentioned prior art, the present invention provides an intelligent solar lawn lamp, which is powered by solar cells, does not need to lay cables, and does not need to consider the safety of cables after long-term use, reducing the risk of s...
