Colorful photovoltaic lawn lamp

Abstract

The invention provides a colorful photovoltaic lawn lamp which comprises a main lamp device. The main lamp device comprises a base support. A lamp cover is fixedly connected above the base support. The area of the bottommost layer of the base support is a loudspeaker box and storage battery storage area. The middle portion of the base support is a hollow part, and a supporting plate used for carrying a signal processing controller is arranged at the position, above the hollow part, of the base support. The lamp cover comprises an upper top plate and a lower bottom plate which are horizontallyarranged. The lower bottom plate is installed at the upper end of the base support, a main lamp illumination lamp is fixedly connected to the middle portion of the lower end face of the upper top plate, and the upper end of the upper top plate is provided with a main lamp solar photovoltaic plate of an off-network photovoltaic device. The main lamp solar photovoltaic plate is connected with a storage battery, music color lamps are fixedly connected to the periphery of the upper top plate, the music color lamps are connected with corresponding music color lamp illumination circuits, and the music color lamps can flicker with different colors along with the music frequency. By means of the colorful photovoltaic lawn lamp, the functions that music can be played, and the music color lamps canconduct illumination and can change the brightness along with music are added.

Description

technical field [0001] The invention belongs to the technical field of lawn lamps, and in particular relates to a colorful photovoltaic lawn lamp. Background technique [0002] Lawn lamps are widely used in public places in cities to play the role of lighting and decoration. There are two main types of traditional lawn lights. One is to adjust the brightness of the light by reducing the average value of the output voltage through thyristor chopping, but the output voltage is no longer a sine wave and accompanied by a large number of harmonics, so it cannot be used in circuits with capacitance compensation; The other is to adjust the taps of the autotransformer, which is not suitable for frequent switching and is accompanied by "flash" phenomenon. [0003] In addition, at present, home garden lights are mostly powered by wires, and the installation is complicated. It usually requires pouring embedded parts, digging cable trenches, laying cables and other processes, which pos...

Problems solved by technology

Traditional lawn lights are mainly divided into two types. One is to reduce the average value of the output voltage to adjust the brightness of the light through thyristor chopping, but the output voltage is no longer a sine wave and accompanied by a large number of harmonics, which cannot be used in circuits with capacitance compensation; The other is to adjust the taps of the autotransformer, which is not suitable for frequent switching and accompanied by "flash" phenomenon

[0003] In addition, at present, home garden lights are mostly powered by wires, and the installation is complicated. It usually requires pouring embedded parts, digging cable trenches, laying cables, etc., which poses safety hazards.
