A brief overview of the special nature of solar lights

Solar street light is a typical independent photovoltaic power generation system, this is just one aspect of the problem, even more serious is that it is a reduction in the amount of solar radiation with the increased seasonal loads. You can see from the above analysis, the annual winter solstice is the minimum amount of solar radiation, which is generating the least amount of solar components, when the annual winter solstice is the shortest day, longest night, when the longest road lighting needs . Currently in the design of solar street lighting problems people are concerned about the continuous rainy days, in fact, this problem is still relatively easy to solve, as long as the increase in the capacity of the battery can be a part of, if you want the winter solstice of road lighting indicators meet the state standards requirements, unless sacrifice spring, summer, autumn generation solar cell modules, no other way. In this case the efficiency of the system will be very low.
In the solar cell power source efficiency in certain circumstances, factors that affect the use of solar street light effects, there are many: the intensity of solar radiation, the solar cell module tilt angle is reasonable, ambient temperature, battery recency (charging old battery and power generation Efficiency can be a difference of more than 30%) and the like. In the absence of these conditions previously determined to evaluate the effect of solar lights is inaccurate.
(1) "can light" does not mean that can meet the state standards CJJ45-2006. Urban road lighting design standards road illumination. Some of the case.
The output power of the light source can vary with the battery voltage, the lower the voltage, the output power is smaller, the illuminance is smaller.

5.5 three-color color energy efficient light switch Speed
This issue is very important, it even determines the service life of solar lawn, up to 10-20 times the starting current three-color color energy efficient lamps started, the system in such a large withstand voltage current situation may have dropped substantially, Solar Lawn not start or start again until the damage.
5.6 boost circuit efficiency and impact of LED lights
Small power solar lawn generally boost circuit, if the oscillation circuit, inductor boost. Inductor using standard color code inductors, standard color code inductor using an open magnetic circuit, a large loss of flux, so low circuit efficiency. If a closed magnetic circuit inductor boost manufacturing, such as magnetic, boost circuit efficiency will be greatly improved. Properties close to the Zener diode LED <http://www.ledgb.com>, working voltage 0.1V, operating current may vary approximately 20mA. For security, under ordinary circumstances the use of a series current limiting resistor, great energy loss is obviously not suitable for solar lawn lights, and LED brightness varies with the operating voltage, and must automatically limit, otherwise it will damage the LED. General LED peak current 50-100mA, anti-reverse-battery or battery energy load, is likely to exceed this limit peak voltage is too high when the booster circuit, damaged LED.In recent years, China's optoelectronics industry has shown rapid growth, has formed a specialized, large-scale photovoltaic industry chain. The state supports photovoltaic building demonstration, implementation of the "Solar Roofs Plan", the financial support for the implementation of solar energy utilization policy. Photovoltaic use of solar photovoltaic power plant projects, solar street lamps and other products at a faster rate in the country is completed, production, optoelectronic products to be applied in practice.

3, solar lantern system design ideas and points
The same basic principles of solar photovoltaic systems, solar lantern design therefore also be based on the general idea of ??a solar power generation system, first determine the power of the solar cell module, and then calculate the battery capacity. But solar street has its particularity, the need to ensure a stable and reliable operation of the system, so they need special attention in the design.
Now, an example of solar lantern system design elements, such as: the need to install a number of solar lights in a city, light power is 30W, the requirements street work eight hours a day to ensure continuous seven rainy days to work properly. Local longitude 114 degrees, 23 degrees north latitude, the annual average daily solar radiation was 3.82 KW.h / m2, the average monthly temperature of 20.5 degrees, the time interval of two consecutive rainy days 25 days long.
Based on the above information, calculate the PV module inclination angle of 26 degrees, a standard peak number of 3.9 hours. (1) load on power consumption
Q = W * H / U = 30W × 8H ÷ 12V = 20 Ah battery where U is the nominal voltage system
The charging current I1 (2) satisfy the load on the power of the solar cell module = Q * 1.05 / h / 0.85 / 0.9 = 7.04 A
Where 1.05 is an integrated solar charging loss coefficient, 0.85 for the battery charging efficiency, 0.9 for the controller efficiency. (3) determine the battery capacity
Meet eight consecutive rainy days working normal battery capacity C
C = Q * (d + 1) /0.75*1.1=20*8/0.75*1.1=235Ah take 240Ah formula for the battery discharge depth of 0.75, 1.1 safety factor batteries. Select two 12V / 120Ah battery comprising a battery
(4) after consecutive rainy days need to restore the battery capacity of the solar cell module charging current I2 I2 = C * 0.75 / h / D = 240 * 0.75 / 3.9 / 25 = 1.85A where 0.75 for the battery discharge depth

Power (5) solar modules for the (I1 + I2) * 18 = (1.85 + 7.04) * 18 = 160Wp
18 is a solar cell module in which the operating voltage, select two peak power of the solar cell module 80Wp
4. Selection of the key components of solar lantern 4.1 solar components
Voltage solar modules will decrease with increasing temperature, due to the effects of high temperatures, the battery pack voltage loss of about 2V, and a diode drop 0.7V charging process controller, so choose the operating voltage of 18V components.
Due to the special nature of solar lights, solar panels are generally mounted on poles,

Combination tone
Survey results, the reporter also interviewed relevant experts, to promote the use of energy-saving lamps in-depth analysis of the status quo. Investigation and analysis showed that one of the main constraints popularity of energy-saving lamps, energy-saving lamps are some consumers still lack a certain understanding. Data show that although China is the world's largest producer of energy-saving lamps, energy-saving lamps in 2005 production reached 1.76 billion, accounting for about 90% of world production, but relatively low level of understanding of people's energy-saving lamps. Survey evidence suggests that there is, because of the low utilization rate of energy-saving lamps respondents "do not understand the product," some respondents confused with energy-saving lamps and fluorescent lamps. Price is another important reason for the popularity of energy-saving lamps constraints. 32.1% of respondents believe that the price of energy-saving lamps too high. Survey, many respondents were positive for the promotion of energy-saving lamps brainstorming. 44.2% of the respondents to the promotion of energy-saving lamps recommendations, including 18.8% expect to increase its efforts to promote energy-saving lamps. 83% of respondents believe that should be forced to promote the use of energy-saving lamps in public lighting. They believe that "energy is imperative, it should limit the development of non-energy-saving lamps at the policy level," "in public places where a large amount of electricity to be widely used even enforced." Some respondents also suggested that should develop "national mandatory standards", "brightness unified energy standards," and so on, so that consumers can rest assured that buy energy-saving lamps. But the survey found that energy-saving lamp production order is chaotic, some of the plants in order to mimic the main.
Emerging LED lighting industry development potential is infinite.
A, LED lighting to highlight energy-saving advantages indicate its future can not shake the current industry leader, according to
Ming accounts for about 20 percent of total world energy consumption. China since 2003, he has frequently encountered electricity shortage crisis, which also led to the social thinking of alternative energy sources and new energy sources.

0%. Reporters will be LED with ordinary incandescent lamp, spiral energy-saving lamps and T5 fluorescent trichromatic do some comparison results showed that: ordinary incandescent light efficiency is 12lm / W, life less than 2000 hours, the luminous efficiency of 60lm spiral energy-saving lamps / W, life less than 8000 hours, T5 fluorescent lamps compared to 96lm / W, life of about 10,000 hours, while the diameter of 5 mm white LED is 20 ~ 28lm / W, life can be more than 100,000 hours. It was also predicted that the future of LED lifetime limit will be infinite. Most people think that energy-saving lamps can save energy 4/5 is a great initiative, but also energy saving lamp LED than 1/4, which is solid light source greater reforms. In addition, LED also has other advantages, high quality light, almost no radiation, is a typical green lighting; reliable and durable, very low maintenance costs, and so on. Because LED light source also has over other solid unbeatable features, 10 years after the LED lighting industry will be the main source.
2, green: LED in the production process do not add "mercury" nor require inflatable, no glass shell, anti-
Impact resistance, shock resistance, unbreakable, easy to transport, very green, known as "green energy"
3, life is very long: generally between 50 000 -10 million hours, because LED is a semiconductor device, even frequent
Fan switch, it will not affect the life
4, the volume is very small LED elements: easier to layout and design of various devices, and can be more
Good night lighting to achieve, "we saw the light but not light" effect
5, a high concentration of light energy emitted by the LED: concentrated in a smaller wavelength window, purity
High.

Solar lighting composition, characteristics and precautions

Accessories features
1. (a) lamp beads
Lamp beads solar lamps the most important components, just started very odd people, why lamp beads price yuan range from 2-10, which is a difference; lamp beads packaging technology, the production environment and the materials used It will affect its price.
(1) get a lamp beads, first look cleanliness, if the potting process is not good, you will see around the overflow of glue dirty, you may also see a lot of bubbles, which is and packaging factory production environment a.
(2) look at the size, shape, solid crystal technology, as well as the size of the lens chip lamp beads.
The size of the lamp beads ranging from 35ml-50ml, prices are very different, for example, if the shape of the wafer sheet will be much cheaper, "the solid crystal" if it is automatic line will be very neat, pc lens, a chip the size you want and matching, if not qualified is very easy to produce very serious spot.

Prospects of solar LED lighting

Eight, solar LED lighting system application:

Application of solar photovoltaic technology has a very important role not only in remote areas and the temporary lack of electricity has also been rapidly growing popularity in other regions, it has been used in transportation, construction, agriculture, forestry and other industries. Especially in the lighting project, it is colorful.

a. urban lighting lighting

Current solar PV technology in urban lighting lighting application has started and rapid development momentum gradually spread application. Signs, warning signs, lawn, etc. may be solar photovoltaic street lighting and technical schools, parks, residential areas, villas and other places to make it easier for public lighting, security, environmental protection and energy saving. Solar lighting lighting works are: solar panels as a power generation system that allows solar panels power through power diode and control system to recharge the battery when the battery power reaches a certain level, automatic protection system operation control system built-in, solar panels automatically cut off the power supply, the implementation of automatic protection. Night, solar panels and light control also played a role, issuing instructions to the control system, then the control system automatically turns on, the output voltage, so that all kinds of lighting to lighting design. And the time required to adjust the lighting.

Solar Landscape design mostly uses a combination of metal and plastic die casting, light body can exhibit a variety of shapes, round, square, geometric patterns and so on, deportment thousands, styles, or luxurious and elegant, or simple and neat. Light body color white, red, green, blue, purple, yellow, etc., followed by gradual or flashes. The system automatically starts after dark lighting device, at first glance, the lamp body to issue a uniform soft light, several colors jump gradient, the city's night rhythm up at the moment. While the solar pole rods generally 8 to 13 meters high, lighting power 50W ~ 130W, effective lighting area of ??up to several hundred square feet. As night fell, neon flashing, Ambilight, exceptionally enchanting.
