FOR IMMEDIATE RELEASE
(Free-Press-Release.com) December 21, 2011 -- Solar Lawn mainly to the use of solar energy to work, when the day sunlight in solar cells, the light energy into electrical energy stored in batteries, and then from the battery in the evening for the lawn of the LED (light emitting diode ) to provide power. The advantage is mainly for safety, energy saving, convenience, and environmental protection. Residential community green grass for decorative lighting, landscaping, parks and landscaping lawn ornament.

A: LED solar lawn composition:

By the solar modules (photovoltaic panels), ultra-bright LED lamp (light source), maintenance-free rechargeable battery, automatic control circuits, lighting and so on.

Two: LED solar lawn lamp system consists of:
Solar lawn boost IC, can automatically switch between charge and discharge behavior, when the solar charging panels during the day when the sun sensor, automatically switch to turn off the lights into the state of charge, when darkness fell less than a solar charging panels when the sun sensor, automatically switch to turn light into the battery discharge state. Solar lawn boost IC, 1.5 volt rechargeable battery can output voltage raised to 3.6 volts.

IC should be a circuit board 5 with a rechargeable battery that can drive 1 - 7 LED light-emitting diodes; sets of circuit board IC so; solar lawn lamp controller and some peripheral integrated circuit elements, Main features include charging circuit, driver circuit, and pulse width modulation control circuit photosensitive circuit. The controller has a high conversion efficiency: 80 ~ 85% (typical value), can reduce the solar cell version of the power requirements; low turn-on voltage: 0.9V (max); adjustable output current and other characteristics.

Three: LED solar lawn lamp advantages:

At present, most lawn use LED as a light source, LED long life, up to 100,000 hours or more, low voltage, suitable for use in solar lawn lights on. LED technology in particular has experienced a breakthrough in the key, and its properties in the past five years has greatly improved, the cost performance is also greatly improved. In addition, LED by the low voltage DC power supply, its low cost, light control, so adjust the brightness, frequent switches are possible, and will not adversely affect the performance of LED. You can also easily control the color, change the distribution of light, resulting in dynamic mirage, so it is particularly applicable in the solar lawn lamp on.

Solar lawn light and power system design unique advantages as solar lawn, rapid development in recent years. Lawn power is small, mainly for the purpose of decoration, the high mobility requirements, difficulty laying circuit, the high water requirements applicable to the venue. These solar-powered lawn makes the show from the many unprecedented advantages.
