Description

Solar LED Lawn Light

technical field

The utility model relates to a lamp, in particular to a lawn lamp using solar energy as an energy source.

Background technique

With the development of society, people also have new beautiful requirements for the environment. At night, colorful lawn lights can decorate parks, roads and the whole city more beautifully. Lawn lamps use incandescent lamps or energy-saving lamps as light-emitting components, and use 220V AC as energy. Wires must be buried. Large, based on an average of 10-11 hours of lighting per night and 25W of incandescent or energy-saving lamp power, the daily power consumption is 90-120 degrees. Existing solar lawn lamps use solar energy as energy and energy-saving lamps as energy, but the energy consumption of energy-saving lamps is large. And it must be lighted when the high voltage is required, so a DC-AC booster circuit is required to raise the voltage to 220V AC, which increases the power loss. Increase the cost, and the service life of energy-saving lamps is about 1200 hours, and the failure rate is also high.

Contents of the invention

The purpose of this utility model is to propose a lawn lamp that can solve the above-mentioned shortcomings and utilize solar energy as energy.

The utility model is composed of a solar battery UT, a storage battery E, a light-emitting diode LED as a light source, and a controller. The controller is composed of a control circuit on a circuit board. It is characterized in that there is an optocoupler IC1 in the control circuit. Pin 1 and pin 2 of IC1 are connected to both ends of the solar cell UT. The solar lawn lamp has a lamp holder, a lampshade is arranged on the lamp holder, a light source is arranged in the lampshade, a solar battery panel and a storage battery are also arranged, and the solar battery panel is arranged on the upper surface of the lamp. The storage battery is arranged in the lamp holder, and the light source is an LED light emitting diode.

The utility model can obtain high illumination in the horizontal direction. Compared with the solar lawn light source with the existing structure, the number of light-emitting diodes is the same, and the horizontal illuminance is increased by 6-10 times. If a lamp with a total luminous flux of 100 lumens is installed in the matching solar lawn lamp, the luminous flux per lumen is only 2.5-3.0 yuan, which is one-tenth of the current market price. It achieves the maximum luminous flux without increasing the area of the solar panel, so that the surroundings of the lamp's illuminant can obtain the maximum horizontal illuminance. Since the solar lawn lamp adopts the LED three-dimensional lamp as the light source, it can satisfactorily solve the above existing problems, greatly promote the practical application of the solar lawn lamp, and will produce huge social and environmental benefits.

The utility model is provided with a control circuit, and the control circuit includes an overcharging and overdischarging protection circuit for protecting the storage battery, a photosensitive switch circuit for controlling the light-emitting diodes to work, and a counting circuit for controlling the light-emitting diodes to work in turn.

The utility model has the advantages of novel and reasonable structural design, power saving, high efficiency, long service life, convenient installation and use, elegant appearance, easy operation and wide application range.
