The light source is an LED light source, and the lamp body is also provided with a raindrop sensor and The controller that controls the rain sensor. The utility model is composed of solar panels, storage batteries, LEDs, cast aluminum lamp bodies, raindrop sensors, etc., and uses the principle of photoelectric conversion, combined with the rich colors of LED light sources, to create a novel, efficient and environmentally friendly lighting system through raindrop sensors. Green and energy-saving solar LED lawn lights; its beneficial effects are: using solar power, no need to lay wires, LED light source works as white light at night on a sunny day, for lighting use, and the sensor controls the LED light source to work in a color state for landscape use on rainy days , both in terms of function and energy saving have a significant effect.

Description

lawn lamp

technical field

The utility model relates to a landscape lamp, in particular to a lawn lamp.

Background technique

With the development of society, people's living standards are constantly improving. In order to beautify the environment, various lawn lights have been set up in various communities, squares, industrial parks, tourist attractions, park green belts and other places. Traditional lawn lamps generally use incandescent lamps or energy-saving lamps as light sources, and are powered by 220V AC mains power. When installing, embedded wires are required, which is unsafe to use. Incandescent lamps and energy-saving lamps consume a lot of energy and have a high failure rate, requiring frequent maintenance. Replacement, and incandescent lamps and energy-saving lamps contain inert gas, which pollutes the environment.

The traditional lawn light source is dull, and the light is directly irradiated around, which will cause glare to the vision.

Contents of the invention

The utility model provides an energy-saving and environment-friendly multifunctional lawn lamp for solving the shortcomings in the use of the existing lawn lamp.

The technical solution of the utility model to solve the existing problems is: a lawn lamp, including a lamp body, a solar panel fixed on the lamp body, a light source, a PC light-transmitting cover, and a storage battery. A raindrop sensor and a controller for controlling the raindrop sensor are also provided. The raindrop sensor includes an infrared emitting tube b and a receiving tube c installed in the filling layer behind the glass of the solar panel.

The utility model is composed of solar panels, storage batteries, LEDs, cast aluminum lamp bodies, raindrop sensors, etc. Compared with the prior art, the utility model uses the principle of photoelectric conversion, combines the rich colors of LED light sources, and creates a raindrop sensor. A novel, efficient and environmentally friendly green and energy-saving solar LED lawn lamp; its beneficial effects are: using solar power, no need to lay wires, the LED light source works as white light at night on a sunny day for lighting, and the sensor controls the LED light source to work in the rainy day In the color state, it can be used as a landscape, both in terms of function and energy saving.

Detailed ways

Referring to Figures 1-4, this implementation case includes: a lamp body 3, which is a solar panel 5 fixed on the lamp body 3, an LED light source 1, a PC light-transmitting cover 2, and a battery 4. The lamp body 3 is an aluminum cast lamp body, and the lamp body The body 3 is also provided with a raindrop sensor 7 and a controller 6 for controlling the raindrop sensor 7 .

During the working process, the raindrop sensor 7 infrared emission tube b and receiving tube c are installed behind the glass of the solar panel 5 and immersed in the filling medium in the filling layer, and the controller 6 sends out a signal to control the infrared rays emitted by the infrared emission tube b to enter the glass In this case, since the incident angle a is greater than 42° (glass-air total reflection critical angle), total reflection occurs on the interface between glass and air, and the infrared rays are received by the infrared receiving tube c through total reflection. The controller 6 determines that it is sunny, and makes the lawn lamp work in a white light mode for lighting. If there are water droplets on the glass, since the incident angle a is less than 63° (glass-water total reflection critical angle), the infrared rays at the interface between the glass and the water droplets are completely refracted into the water droplets, and the infrared rays cannot be reflected to the receiving tube c, and the receiving tube c The signal is fed back to the controller 6, and the controller 6 judges that it is rainy and then controls the switching circuit of the light source part, so that the lawn lamp works in the color light node mode for landscape use.

In addition, the lamp body of the utility model adopts electrostatic spraying and high-temperature baking, which is more suitable for outdoor harsh environments.
