Dosti Pehli Baarish Ki Boondo Mein Hai
Dosti Khilte Phool Ki Khushbu Mein Hai
Dosti Ugte Suraj Ki Kirno Mein Hai
Dosti Har Naye Rishte Ki Umeed Hai
Dosti Khwaab Hai, Dosti Jeet Hai
har kisski taqdeer itni acchi nahi huti
har kissku acchi dosti naseeb nahi huti
wo tu khuda ki mahrbanni hai
jisku zarurat padhti itefaaq se miljati hai
nahi tu taqdeer itni acchi kisski huti.............
zindagi me kabhi khusi kabhi ghum hute hai
aisse waqt me dost hi hamare humdum hute hai
janne log kaisse ghum me bhi haste hai
shayad isiliye kyoun ki dost hamare sath hardum hute hai
Tujh ko dunya se fursat mile to tujh se poochon...
Yaad bhi atay hain tujhe DOST purane waalay...
Ek tu hai jise bhool na paye hum...
Warna andaaz to atay hain hamen bhi zamane waalay..
Always
your eyes might not find
a friend when you need
look through your heart
the friend is there indeed
Jo Mushkil Aasan Banate Hain
Jo Dushman Ko Girate Hain
Jo Hunste Aur Hunsate Hain
Un Ko Bhala Kia Kehte Hain?
Un Hi Ko Dost Kehte Hain
Dosti ka samandar ha buhut gehra
Her taraf nazar aya tera hi chehra
Tum ho eik chamkta damaktaa sa sitaraa
Teri chamak se hota ha pareshani mai khoshi ka sawera
Ata ha logo logo ko ainee mai nazar aksi chehra
Hum ap ki yad me udas hain
bas ap se milne ki hi aas hai
chahe dost kitne bhi kiu nah hon
apne liye to bas ap hi kuch khaas hain.
Dunia me dost bohat kam mile ge
A dost tuje chahane wale cam nahi milege
mill jayge hum jese pr hum nahi milege
Karz dosti ka Koun ada karega.
Dost na ho to dosti kaun karega.
DOSTI gazal hai gungunane ke liye
DOSTI nagma hi sun sunane ke liye
ye woh jazbaa hai jo milta nahin sab ko
kiyon ke hosila chahiye DOSTI nibane ke liye
lamha-lamha waqt guzer jaye ga
1 Overview of solar lighting
Solar energy is “inexhaustible”, and pollution-free renewable energy, radiant energy, the Earth’s surface every day to approximately 2.5 millions of barrels of oil. A long period of time, solar energy from the people around were in vain, “slip” of the.With the rapid development of science and technology, development and utilization of solar energy gradually, and has become the most promising environmentally friendly energy sources.
At present, solar energy, there are two main ways.
(1) through the solar cells convert solar energy into electrical energy for power generation, namely photovoltaic power generation, such as solar lighting, solar power stations and so on.

At present, solar energy, there are two main ways.

Solar energy – the energy of this century one of the major human.By 2030, the world’s electricity production will mainly rely on solar energy. Solar energy as a non-polluted environment, but also an inexhaustible supply of new energy will be everywhere. Solar photovoltaic products is through the effect of light under the sun, into electricity process, is a use of high-tech development of new energy, mankind yearns for the 21st century, the pursuit of new sources.
Solar lights and solar power generation systems and other products of the main innovations:
01 energy, which uses natural light, without consumption of energy, and inexhaustible not finish;
02 environmental protection, in line with environmental protection requirements, no pollution, no radiation, ecological protection;
Solar photovoltaic technology is not only a temporary lack of electricity in remote areas and areas with a very important position, in other areas have also been rapid spread has been applied in transportation, construction, agriculture, forestry and other industries. Especially in the lighting project, it is colorful.
The city solar lighting
The current solar PV technology in the lighting of urban lighting has been started and the momentum to the gradual popularization of the rapid development of applications. Schools, parks, residential areas, villas and other places of signs, warning signs,

As the Earth’s resources become increasingly scarce, increasingly based on investment costs of energy rising, and a variety of safety and pollution problems can be described as ubiquitous. Solar energy as an “inexhaustible” security, environmental protection and new energy sources more and more attention. Thus, solar lighting products with the popularity of solar water heaters after the students should, however, where we use solar lighting and electricity for lighting effects and practical contrast.
Compare one city to install electric lighting complex: in the city lighting project has a complex operating procedures, the first laying of cables; cable channel will be carried out here, excavation, laying of underground pipe, pipe threading, backfill and other large infrastructure projects.
This is an typical example of making use of solar lighting.
Villagers of Quorn are hoping the strange situation of a footpath left half lit by street lamps and half in darkness is set to be resolved.
Quorn was one of the first villages to volunteer to be part of a County Hall trial scheme earlier this year and had some of its street lights turned off between midnight and 5.30am to save money on electricity bills.
But the move has left a 200-yard footpath from the village churchyard to Mansfield Street, known as Love Lane, in the position of being illuminated for part of its length before being plunged into.

I. Background, purpose and meaning
As a global energy crisis, the world generally given to renewable energy use and research. Solar energy as an emerging green energy, with its inexhaustible, pollution, etc., are being rapidly
The application. solar lighting do not hand in its management and control, install a one-time investment in electricity costs without future, without setting up transmission lines or trenching cabling. Can be easily installed in Plaza, schools, parks, and not easy to set up transmission lines and many other advantages place more and more attention.

1.1 The need for new energy development
Generally believed that the excellent performance of the solid LED as a light source, white LED is the most promising. Therefore, many countries have invested heavily in actively high power, high efficiency white LED. There are already commercial lighting level white LED, the price is constantly declining.
1 white LED performance
(1) the characteristics of white LED
White LED lighting-class power for the W, 3 W, 5 W, 0 W, 5 W,
The so-called white LED lighting level is the single package, with a “W” 20 W and other products.
(2) the curve parameters of white LED

Section1 the basic concepts of solar photovoltaic
First, the basic concept
Solar photovoltaic system is the use of solar photovoltaic effect of semiconductor materials, the solar radiation directly into a new electricity generating system. Photovoltaic power generation system is to convert solar energy into electrical energy generation system, the use of the photovoltaic effect. The main components of PV systems are solar cells, batteries, controller and inverter.
