Solar LED Lighting System

The basic principle of the case where there is light of solar LED auto lighting system, the solar panels turn the light energy into electrical energy for battery charging, and store the electrical energy in the battery. At night, This battery power effects to play for LED lighting. This System uses automatic work without manual intervention, can be control as sound, light and time delay control mode, keeping "people at the lights, people take the lights turned off" (referring to the corridor, corridors, etc.) or "dark or bright, delay turn off the lights " or 24 hours a day," always lights, "(referring to underground car parks, tunnels, etc.). Pairs of consecutive rainy days, the system can set the number of days (5-7 days) work properly. The lighting system device is a new generation of energy (solar, wind, etc.) and next-generation light source (semiconductor LED) in the most direct and most economical combination the 21st century.

Technical Features

Solar LED auto lighting system features and advantages of concrete in the following areas:

First, mixed analog and digital control technology. Solar LED automatic lighting control system uses light-sensitive element of the evening, the light intensity detection, the control system input analog signal, after digital circuit processing, and the darkness in the right automatically open when the lighting circuit, and intelligence to deal with short-term non - The darkness of night lighting.

The second is many multi-pole lamp uses one solar PV systems. All solar street lights are used to focus power, centralized control technology, and there have been over-discharge protection device charge. Corridor lighting use one set of lighting system each building; roads, courtyards, regional, lawn lighting light of local conditions is also a multi-pole light to share a set of large-scale solar photovoltaic conversion, storage and control systems, lighting from several shots to the dozens of shots, Solar panels power from 100 watts to several kilowatts. The advantage is reasonable to design preparation, saving solar panels; easy to analog and digital control of the set or reset; better use of external power supplies automatically switch charging, automatic tracking solar panels and other new technologies; adaptability, not subject to lighting conditions , under a tree, Lou road, basements and tunnels can also be used; without regard to wind loads, snow load on the impact of the poles, can reduce the cost of lighting and infrastructure; batteries centrally located, easy maintenance, replacement and use of working condition.

The third is to do with the semiconductor light-emitting LED light source assembly of components, such as large-scale street lighting. To do with the LED light source assembly of small lamps are more, but in other large solar street lamps on the domestic energy-saving lamps do generally use the light.

Fourth, the work of state control over battery. Batteries are the key components of solar lighting. Because the system must have redundant design, battery capacity relative demand as large, thus affecting their work activity, resulting in effective capacity gradually decreased. Battery capacity in the system of flexible options, intelligent combination and make overcharge, over-discharge protection and anti-down charge setting, can be battery doubling the effective capacity of the time about this technology in large-scale street light systems and large-scale landscape lighting System effects are particularly obvious.

Five is solar photovoltaic electricity and automatic switching technology. Annual rainy season or winter, the eastern areas will occur 1-2 weeks continuous wet weather, resulting in auto lighting system, solar energy is not enough storage capacity, affect the normal lighting.
