The ice and snow art landscape originated in Harbin. Due to the use of ice and snow as a performance carrier, it has formed a very unique landscape art culture. At present, it has developed into the world's largest ice and snow art landscape, and has formed a unique tourism culture industry with local characteristics. .
Problems and challenges
Ice and snow art landscape is a combination of ice and snow architecture and lighting art. Ice and snow are carriers, and lighting is the soul of ice and snow landscape. The light of the snow and ice landscape has undergone a history of candlelight, incandescent lamps and fluorescent lamps. Although the ice and snow landscape sculpture and architectural art are becoming more and more perfect, the traditional light source of its application has seriously hindered the improvement of the ice and snow landscape art. The main reasons are as follows:
(1) The traditional light source can't realize the dynamic conversion effect. The static landscape lighting effect that has lasted for nearly 40 years has hindered the improvement of the ice and snow landscape art. The most urgent need is to transform the frozen ice and snow landscape into dynamic, The landscape art of vitality.
(2) The dysentery that cannot be recycled by traditional light sources has brought enormous financial pressure on the construction of ice and snow landscapes. Traditional incandescent and fluorescent lamps are fragile and unrecyclable, requiring repeated inputs every year, and heavy metals in scrapped light sources seriously contaminate the environment. Taking Harbin Ice and Snow World as an example, the number of fluorescent lamps applied in ice and snow landscapes is as high as 400,000 per year. After the landscape is melted, the fluorescent lamps are directly scrapped. The mercury in the lamps has caused serious pollution of 540,000 m3 per year.
(3) Green energy conservation is the development trend and direction of the ice and snow art landscape tourism culture industry. An important cost investment in the world of ice and snow every year is the electricity cost. The traditional light source has low light efficiency, especially in low temperature operation environment. Therefore, the use of green energy-saving lighting source is an effective guarantee for energy saving in ice and snow landscape.
In this context, LED light source has gradually become the development trend of ice and snow landscape lighting with its many advantages. Compared with traditional light sources, LEDs have outstanding advantages such as energy saving, longevity, high reliability, environmental protection, and easy dimming control. However, LED lighting belongs to the emerging industry, especially in the application of ice and snow landscape. Therefore, the research and development of LED light source must clearly grasp the unique lighting characteristics and data indicators of LED, in order to finally meet the demand. So let's take a look at what the ice and snow landscape has for LED lights.
Demand characteristics of ice and snow landscape lighting
From the perspective of the landscape design side, the most concerned issue is the light-emitting effect of the LED luminaire in the ice body, the saliency of the brightness and the stunt display effect that the lighting control system can achieve. The designer must pre-evaluate the design by understanding the content and modeling the ice building modeling and lighting effects to determine the overall artistic effect of the solution. This is an indispensable process for establishing an objective evaluation system for the ice and snow landscape design.
PTFE Fabric With Acrylic Adhesive is made from a very tightly woven fiberglass cloth which has been heavily coated with PTFE resin and has a high temperature acrylic adhesive applied to one side. The combination of PTFE and its well known properties, the excellent strength and dimensional stability of the fiberglass, and a high temperature range of the adhesive system results in a product appropriate for use in a variety of high temperature and demanding applications. The product has a greater PTFE coated weight providing a smoother surface with enhanced durability compared to Standard acrylic adhesive tape.
Yaxing provides very thin thickness and special compound skived tapes from 0.08mm to 0.38mm, whose excellent and stable quality only the most advanced technologies, the most selected raw materials and skilful experts could granted.
Characteristic
- Low friction coefficient
- Hardness and wear strength
- Extremely high service temperature
- High resistance under pressure
- Extreme longevity therefore resulting in low operating costs
