First, background:

(a) the current situation of the development of LED decorative lighting market

LED light source (semiconductor light source), as the fourth generation of light source invented by human being, is known as the revolution of the development of the lighting source after Edison invented the electric light. After decades of time, technology has made rapid development.

At present, the field of domestic LED decorative lighting, the annual market size has reached 20 billion yuan, due to the advantages of energy saving, long life, environmental protection, from 2005 to 2007, LED decorative lighting market growth rate of about 25%. The 2008 Olympic Games the "bird's nest" and "Water Cube" landscape lighting projects all the light by LED, and the formation of landscape lighting effect in the world beyond the short time, for the development of LED lighting landscape into a more powerful driving force. According to the national semiconductor lighting leading coordination group predicts that in 2008, the national LED landscape lighting market will have explosive growth, industry output value will be more than 30 billion yuan. LED light source has become the main source of decorative lighting.

An overview of the development. The Harbin ice art and Harbin ice and snow world

Harbin as the birthplace of ice art, since the last century since 50s, based on innovation, design of ice landscape excellence, always in the lighting is also explored, and made progress, from the initial development of a candle and the incandescent lamp fluorescent lamp. Light promote the progress of development of ice art, the increase in beauty at the same time, more secure, and the system of modernization, Harbin has formed a snow brand of cultural tourism industry.

Harbin ice and snow world is in such a big environment, by the end of 1999 with the opportunity of the turn of the century, to create a theme park with snow and ice. Harbin snow world planning covers an area of 400 thousand square meters, with an annual amount of ice in the amount of 120 thousand cubic meters, with a volume of more than 80 thousand cubic meters of snow. More than 2000 pieces of art works, more than 30 items of entertainment projects, are the world's most ice and snow art.

Harbin ice and snow world in the beginning is hosted by the Harbin municipal government investment, from the beginning of the fourth session of the group of independent contractors by modern, and the Sun Island is located in the west of the permanent Park site. Successful market operation, enterprise management so that the world of ice and snow in Harbin is becoming more mature, the number of visitors year after year. By ninth, the number of visitors per year has reached 700 thousand people. Harbin ice and snow in the world of ice and snow landscape creativity and volume every year a new breakthrough. The third session of the fourth session of the millennium, the snow tower, the fifth session of the sixth session of the Three Gorges Dam, the seracs, seventh session of the Hongta tower all previous records. Which 18 meters high, the length of 70 meters of the Three Gorges Dam landscape hit the world record of ice and snow art building volume. The eighth Harbin world ice and snow for the first time the introduction of foreign capital, China and South Korea to fully integrate the advantages of resources, give full play to the wisdom of South Korea and ahead of the imagination, with modern light sparkling ice architecture and colorful forms a surreal world of ice and snow world a magnificent.

Application of LED decorative lighting. In snow and ice in the world

From December 2006 to March 2007, the science and Technology Department of Heilongjiang Province, the semiconductor lighting ice test was carried out for three months in the ice world, completed a feasibility test of low reliability and optical effect of application etc.. All equipment in the field after three months of all-weather outdoor winter environment, the minimum operating temperature of minus 30 degrees, experienced a number of wind and snow test, every day in a stable state of operation. After the equipment is fully recovered, the key components of all equipment are tested, all in the normal working state, LED light-emitting devices without a damage, attenuation and color drift phenomenon. This fully proves the reliability and stability of LED products in low temperature and cold working environment.

In 2007, the main landscape in the world of ice and snow, "Olympic Santa" completed a small scale of the promotion of the application (light coverage rate of about 10%), becoming the only dynamic landscape of the entire landscape and the biggest bright spot. After more than two months of operation, equipment recovery rate of over 90%, simple maintenance, all equipment back to normal. So far, the feasibility of combining LED decorative lighting and ice and snow landscape was effectively confirmed.

The LED decorative lighting research and promotion work, as the project unit Harbin modern group, project coordination unit of Harbin Electronic Institute of computing technology, the CLP Group 13, full integration of resources, including the specific study of the optical properties of materials, properties, electronic control technology, system reliability research, snow facade artistic effect study on the performance and effect of the performance of lighting art, with obvious characteristics of ceusri.

* * to hold the first international ice LED landscape lighting design innovation contest "," LED lighting seminar "as the driving force, to accelerate the combination of LED and ice art landscape, and LED decorative lighting in the field of snow and ice landscape industrialization development.

Two, problems and challenges

Harbin ice art has developed more than 50 years, Harbin ice and snow world has successfully held nine sessions, has become a representative of the landscape of North snow tourism industry,
