Solar energy-saving lighting working principle is through the solar cell work, in the sunshine environment to convert a quantitative solar energy storage in the battery, in the nighttime need to illuminate, the power directly into the lighting use. With the increasingly poor resources of the earth, the cost of basic energy investment is rising, all kinds of safety and pollution hidden dangers are everywhere. Solar energy as a "inexhaustible" security, environmental protection of new energy more and more attention.
Solar energy as a new green energy, with its unparalleled advantages to be rapidly applied. As the fourth generation of new light source, in the city lighting landscaping, road lighting, courtyard lighting, indoor lighting and other fields of illumination and application has been effectively used. Especially in remote areas, solar LED lighting has a wide range of application prospects.
However, solar energy-saving lamps have a lot of restrictions, in the field of solar energy in the use of new breakthroughs in technology, there is no comprehensive conditions.
At present, the application of solar energy-saving lighting is mainly some outdoor public lighting facilities, such as residential green belt, industrial zone green belt, landscape lighting, tourist scenic spots, parks, courtyards, square green space and other places of lighting use. Outdoor facilities can ensure adequate solar energy supply, and through the intelligent control switch, can be effective energy saving and ensure the stability of the lighting effect.
Comparison between solar lamps and ordinary lamps
Solar lighting products with the popularization of solar water heaters should be born, here we have a practical comparison of the effects of solar lamps and the use of mains lamps.
In the mains lighting project has complex operating procedures, the first to lay the cable, here will be cable trench excavation, laying dark pipe, pipe threading, backfill and many other basic projects. Then for a long period of installation and commissioning, if any one line has problems, then large area rework. and the terrain and lines require complex, artificial and ancillary materials to be costly. Solar Lighting Installation Simple: Solar lighting installation, do not have to lay a complex line, as long as a cement base, and then with stainless steel screws can be fixed.
Mains lighting work has a fixed high electricity tariffs, to long-term uninterrupted line and other configuration maintenance or replacement, maintenance costs increased year by year. Solar Lighting lamp-free electricity: Solar lighting is a one-time investment, without any maintenance costs, three years can be recovered investment costs, long-term benefits.
Due to the construction quality, Landscape engineering transformation, material aging, power supply is not normal, water and gas pipeline conflict, etc. bring many safety risks. Solar lighting no security hidden trouble, solar lamps are ultra-low pressure products, safe and reliable operation.
Solar lamps are widely used in the field
Solar lamp, can be widely used in grasslands, squares, parks and other occasions embellishment decoration, belongs to the technical field of lighting. The main use of the lampshade connected to the bottom, the battery plate placed on the battery box inside the lampshade, the battery box installed on the bottom, light-emitting diode installed on the battery board, solar panels using wire connection rechargeable battery and control circuit. The utility model is integrated, simple, compact and reasonable; no external power cord, easy to install, pleasing in appearance; because of the use of light-emitting diode placed in the bottom of the lamp, the light after the entire body is illuminated, the light sense effect is better; all electrical components are built in, and have good practicability. including serpentine lights, plate-type lights, solar neon lights, massage lamps and many other.
In practice, of course, solar outdoor lighting is a bit more complicated. In addition to high-capacity batteries and solar panels, the system also includes advanced dedicated monitors, and when the lighting is stopped, solar-powered batteries start charging and then recharge, and get more power. The key is solar outdoor lighting, solar photovoltaic house installed solar panels, have a dedicated microprocessor control system and batteries. It is connected to a specially designed load lamp with a super reflectivity and high energy ballast. It has the advantages of high brightness, simple installation, reliable work, no cable laying, no consumption of conventional energy and long service life. The use of high brightness led light-emitting diode design, no need for manual operation, dark lights light up automatically, Dawn automatically extinguished. Product fashion sense of strong, beautiful texture, fine, with a modern sense, mainly used in Community green belt, industrial park Green belt, tourist scenic spot, park, courtyard, square green space and other places of lighting decoration.
Basic classification of solar energy
⑴ Solar home lighting and ordinary LED lamp, solar lamp built-in lithium batteries or lead-acid batteries, external one or more solar panels to its charge, the general charge time is about 8 hours, the use of up to 8-24 hour. Generally with charge or remote control functions, the shape varies according to the user's needs.
⑵ Solar signal navigation, aviation and land traffic lights role is critical, many local power grids can not power, and solar signal can solve the power supply problem, light source to small particles directional light-emitting led. has achieved good economic and social benefits.
⑶ Solar Lawn lighting source power 0.1~1w, the general use of small-particle light-emitting diode (LED) as the main source. Solar panel power of 0.5~3w, can be 1.2V nickel battery and other two batteries.
⑷ Solar landscape lamp used in squares, parks, green space and other places, the use of a variety of small power LED light source, line light source, there are cold cathode modelling lights to beautify the environment. Solar landscape lamp can not destroy green space and get better landscape lighting effect.
The ⑸ solar indicator lamp is used to illuminate the night direction, the house number and the intersection mark. The luminous flux of the light source is not high, the system configuration requirements are low and the usage is larger. The light source of the marking lamp can use small power LED or cold cathode lamp generally.
⑹ Solar Street lamp is used in village road and Rural Road, which is one of the main applications of solar photovoltaic lighting devices at present. The use of light source has a small power high-pressure gas discharge (HID) lamp, fluorescent lamp, low pressure sodium lamp, high-power led. Due to the limitation of its overall power, there are few cases applied to the urban main road. With the complementarity of the municipal line, Yu Xiang solar photovoltaic lighting lamps in the main road will be more and more applications.
⑺ Solar insecticidal lamps are used in orchards, plantations, parks, lawns and other places. Generally using fluorescent lamps with a specific spectrum, the more advanced use of LED Violet light, through its specific spectral line radiation trapping pests.
⑻ Solar flashlight using LED as a light source, can be used in outdoor activities or emergency situations.
Solar garden lights are used in urban roads, commercial and residential areas, parks, tourist attractions, squares and other lighting and decoration. Can also be based on user needs to change the above-mentioned mains lighting system to create solar lighting system.
Solar lighting is a new energy trend.
Here we analyze the status and trends of solar lamps:
Technology breakthroughs are needed for full popularization
Solar cells in the project, located in the industrial source of silicon material is heavily dependent on Europe and the United States, Japan and other countries, the application market is mainly dependent on the international market. The shortage of silicon material has become the main bottleneck restricting the development of China's solar cell industry. At present, the domestic solar energy acquisition and conversion of energy technology is not mature, energy conversion efficiency is still low, and the requirements of sunshine conditions are more stringent, in cloudy days or sunny weather is difficult to collect enough solar energy, also can not meet the needs of night lighting.
Second, the use of solar lighting is narrower, on the complex floor of residential areas, only the top floor of the residents can meet sufficient lighting conditions, other floors of the residents can not play the lighting effect of solar lighting.
Finally, solar energy lighting in the conversion of solar energy into electricity and the process of collecting solar energy also needs to consume conventional power, many domestic production of solar energy lighting manufacturers have not yet reached the standard, resulting in energy consumption is higher than ordinary LED lamps, and even to achieve the energy consumption level of incandescent lamps. Plus its cost is higher than ordinary LED lights, so especially for home applications, is not a particularly ideal choice.
The prospect of a vast solar energy application is an irreversible trend
Compared with the international development of photovoltaic power generation, China lags behind the developed countries for 10-15 years. China's photoelectric industry is growing at 30% per year, the national construction of a new socialist countryside, the call of the next 5 years of energy down 20% hard, which provides unprecedented business opportunities for the solar industry, coupled with the country's renewable resources and development of preferential policies have been implemented, in such a good industrial base, The whole society and the country will have big output as long as small investments.
Solar energy development mainly in three directions, namely solar photovoltaic power, solar cells and solar water heaters. The use of solar photovoltaic power generation is an irreversible trend of energy use. China has become the world's second-largest power consumer market after the United States, with demand growing at the top of the world. But the tension of petroleum energy, the shortage of coal resources make the existing power generation way can not meet the demand of electricity consumption, the popularization of solar power is very urgent, the market potential is very huge. For the market, accelerate the development of the solar cell industry must be promising.
