LED courtyard lamp is a kind of outdoor lighting lamps and lanterns, the light source is to use a new type of LED semiconductor as a luminous body, usually refers to the outdoor road lighting lamps and lanterns is 6 meters, the main components by: LED light source, lamps and lanterns, light pole, flange, the foundation embedded parts of 5 parts, because the LED garden light its diversity, beautiful sex has the characteristics of beautification and decoration environment, so also known as landscape LED garden light. LED has the characteristics of energy saving and high efficiency. It is mainly used for outdoor lighting in urban slow lane, narrow lane, residential area, tourist area, park, square and other public places. It can prolong people's outdoor activities and improve the safety of property.
LED courtyard lamp is mainly composed of five components:
(1). LED lighting system: LED light source system includes heat dissipation, light distribution and LED module.
(2). Lamps: LED lighting system is installed inside lamps. Cut wire as wire, take 1.0mm? Red and black copper core multi-strand wire, each section 6 section 40mm, both ends strip head 5mm, and dip tin. Make lamp board lead, take yc2x1.0mm? Two core wire, a section of 700mm, inner end peel 60mm, brown wire stripping head 5mm, tin immersion; Blue strip head 5mm, tin impregnated. Peel off 80mm outer skin and 20mm brown wire peel head; Blue thread stripping head 20mm.
(3). Light pole: the main materials of LED courtyard light pole are: equal-diameter steel pipe, heterosexual steel pipe, equal-diameter aluminum pipe, cast aluminum lamp pole and aluminum alloy lamp pole. The diameter of the commonly used have, 60, 76, 89, Φ Φ Φ Φ 100, 114, 140, 165, Φ Φ Φ according to different height and the place, the selected material thickness is divided into: wall thickness, wall thickness, wall thickness 3.0 3.5 2.5. (above are normal sizes)
(4), flange and basic embedded parts: flange is an important component of LED garden lamp pole and ground installation. LED courtyard lamp installation method: before installing LED garden light, need according to the manufacturer to provide standard flange size, use the M16 or M20 (commonly used specifications) screw welded into a cage, and then in the installation location, the excavation, appropriate size of the hole, the foundation cage placed among them, the level of correction after using cement concrete casting based on fixed cage, 3-7 cement concrete fully solidified in the future, can install garden light. (note: the embedded pipes need to be drawn out when the LED courtyard lamp foundation is poured).
1). On July 1, 2007, the street lamp design standard "urban road lighting design standard" (cjj45-2006) formulated by the ministry of construction was implemented.
2). In January 2008, the ministry of finance and the national development and reform commission jointly issued the interim measures on the management of subsidy funds for the promotion of efficient lighting products, which will focus on supporting efficient lighting products to replace incandescent lamps and other inefficient lighting equipment in use with indirect subsidies.
3). In April 2009, the ministry of science and technology launched the policy of "ten thousand lamps in ten cities", which has driven the development of LED street lamp technology and products in China.
4). On July 1, 2009, LED street lamp (DB44), the local standard of LED street lamp drafted by famous enterprises in guangdong province, was officially implemented.
With the global economic growth, the global street lamp market will show an increasing trend year by year. In 2010, the global street lamp market size reached about 160 to 180 million.
LED garden lights may not be growing as fast as expected in 2009, but it is sure to replace traditional garden lights. Many LED companies compete to invest in research and development of LED garden lights, hundreds of LED garden lights have been launched, but most have not achieved mass production. Compared with the enthusiasm of LED garden lamp companies, China's LED garden lamp market has not yet made efforts in 2009. According to statistics, in 2009 China's LED garden lights market scale is only 20-300000, in the next few years, and thousands of thousands of light the lamp in ten city slogans such as policies, China LED lights market still maintain rapid development speed, predicts 2012, the size of the market will grow from $2008 in 560 million to 3.96 billion yuan, the compound annual growth rate of 63.0%.
