Demand characteristics of leds in the snow and ice landscape lighting applications

Originated in Harbin ice and snow art landscape, with snow and ice as the carrier, thus formed the unique landscape art and culture. At present, has developed into the world's largest ice and snow art landscape, and formed the unique local characteristics of tourism cultural industry.

1 problem and challenges is ice and snow art landscape architecture and art combination of lamplight, snow and ice ice and snow is the carrier, the light is the soul of snow and ice landscape. Snow and ice landscape experienced incandescent light bulbs, candle light, fluorescent lamp by the lights of the such a development. Despite increasingly perfect snow and ice landscape sculpture and architecture, but the application of traditional light source has seriously hindered the snow and ice landscape artistic effect, main reasons are the following several aspects:

( 1) Traditional lighting effect of light source is unable to realize the dynamic transformation, continuation of nearly 40 years of static landscape lighting effect has hindered the promotion of snow and ice landscape art effect, at present the most pressing need is: the solidification of snow and ice landscape into a dynamic, living landscape art.

　　（ 2) Traditional light source in the recycling ills of snow and ice landscape construction brought great pressure. The traditional incandescent lamp and fluorescent lamp vulnerability, unable to recycle, must be repeated every year investment, and scrap material seriously polluted the environment of heavy metals in the light. In Harbin ice and snow world, for example, every year in the snow and ice landscape application of fluorescent lamp number is as high as 400000, landscape fluorescent lamp directly after melting scrap, inside the tube of mercury in songhua river water quality has caused serious pollution each year 54 cubic.

　　（ 3) Green energy saving is ice and snow art landscape tourist culture industry development trend and direction. Every year is an important cost of ice and snow world into electricity costs, the traditional light source, low light efficiency, especially in the energy consumption more running in low temperature environment, so the green energy-saving lighting light source is an effective guarantee of snow and ice landscape save energy consumption.

in this context, LED light source with its own have many advantages, has become the development trend of snow and ice landscape lighting. Compared with the traditional light source, LED in energy saving, long life, high reliability, environmental protection, easy to change light color control advantage is very outstanding. But LED lighting belongs to the emerging industries, especially in the application in the field of snow and ice landscape has more challenging, so using LED light source of research and development work must be clearly grasp the LED lamps and lanterns unique luminescent properties and data index, can eventually conform to the requirements. So, let's take a look at the snow and ice landscape of LED lamps and lanterns is what are the requirements.

2 snow and ice landscape lighting for think in terms of the landscape design, the most concern is cast light effect of LED lights in the ice, brightness of significance and lighting control system can realize the stunt show effect. Designed to understand the content, and through the ice building modeling and lighting effect to preliminary design scheme evaluation modeling way, evaluation method using a combination of subjective evaluation and objective evaluation. Subjective evaluation from the perspective of artistic quality, can be ornamental, objective evaluation from the perspective of visual intensity and visual significance, the final solution of the overall artistic effect. It is the snow and ice landscape design scheme to establish objective evaluation system of a necessary process. Think in terms of construction of the landscape, there are mainly two aspects: one is easy installation, high reliability. Easy installation emphasis is to guarantee higher construction efficiency, no training, connection with bare hands fast, just a tool, and even to complete; High reliability emphasizes the LED lighting system, low failure rate, to ensure the efficient and smooth, without changing repair the installation process. Snow and ice landscape is only a short construction period of 15 days, and it is in the outdoor environment construction below minus 20 degrees Celsius, very poor construction environment and of project period requirement, for the LED lamps and lanterns product reliability and convenience of installation and debugging of the raised very challenging requirement, is also an important guarantee of project smooth implementation.

from the landscape business owner's point of view, on the basis of meet the requirements of design and construction of, to ensure that the energy saving, good recyclability, low cost three requirements. Energy requirements better implementation, because LED lights itself is better than color package fluorescent light efficiency is high, and low temperature condition, smooth effect more evident difference, plus variable light color control factors, so snow and ice landscape LED lighting energy saving effect is much better than fluorescent lights. Good recyclability must reposition the protection level and the impact level of lamps and lanterns, in general, the degree of protection to at least IP67, impact resistant level to achieve IK08 above. Integrated after the above two requirements, but also improve the performance of the product price is as far as possible, meet the landscape of the reach of the business owners.

all in all, the designer's requirements is a 'good performance', the requirement of the construction is 'simple and quick,' the requirements of the business owners are 'cheap', product manufacturers to provide LED lamps and lanterns, must be based on the above characteristics to tailor, can fully meet the needs of all aspects.
