The disadvantages of this kind of solar lawn lamp are: firstly, after installing the solar lawn lamp, many people, especially children, are attracted to watch in the lawn, so that the lawn is destroyed, and the ground near the solar lawn lamp is quickly exposed; Because the LED lamp is arranged in the cylindrical transparent lampshade, the cooling effect is not good, which affects the service life of the LED lamp.

Contents of the invention

The purpose of this utility model is to provide a solar lawn lamp with a lawn care warning device that can not only emit the brilliance of embellishing the lawn at night, but also warn people who enter the lawn to care for the lawn, and improve the service life of the LED lamp. .

In order to achieve the above purpose, the technical solution adopted by the utility model is: the solar lawn lamp with a lawn care warning device includes a solar panel, a battery, an LED lamp bead and a control circuit board, and the control circuit board is provided with a light The control switch circuit, the solar panel is connected to the control circuit board through wires, and the control circuit board is connected to the battery. on the cylindrical aluminum substrate; the storage battery and the control circuit board are installed on the bottom wall of the cylindrical aluminum substrate, and the solar battery panel is installed on the upper oblique opening of the cylindrical aluminum substrate, and on the bottom of the cylindrical aluminum substrate Connect the speaker, and set a bracket on the bottom wall of the speaker; fix the infrared sensor probe on the edge of the upper bevel of the cylindrical aluminum substrate, and cover it with a hemispherical Fresnel transparent cover, and the infrared sensor probe passes through the wire It is connected with the infrared induction control circuit on the control circuit board, the power supply of the infrared induction control circuit is provided by the storage battery, a sounder is arranged on the bottom wall in the sound box, and the sounder is connected with the infrared induction control circuit on the control circuit board.

The utility model is also implemented through the following measures: the circuit on the control circuit board, the infrared induction control circuit on the control circuit board and the infrared induction probe are all known technologies, so they will not be described in detail.

A total of 12-24 LED lamp beads are arranged around the cylindrical aluminum substrate, and the power is 1-2 watts.

The thickness of the cylindrical aluminum substrate is 3-5mm, and the inner diameter is 16-22mm.

Three brackets are equidistantly arranged along the periphery of the bottom wall of the sound box, and are used for insertion into the ground for fixing.

The solar cell panels described are polycrystalline silicon solar cell panels, which can be purchased directly.

The beneficial effects of the utility model are: compared with the solar lawn lamp currently used, due to the addition of a warning device when someone approaches, it not only has energy saving, easy installation, and ornamental effects, but also has a protective effect on the lawn; The cylindrical aluminum substrate is equipped with LED lamp beads, so the heat dissipation performance is improved and the service life of the LED lamp beads is improved.
