The Qinghai-Tibet Plateau is the highest plateau in the world, with an average altitude of over 4,000 meters. It is known as the “roof of the world”. Lhasa, as the capital and economic center of the Tibet Autonomous Region, is like a crown on the plateau. The Potala Palace is undoubtedly the most brilliant pearl in this crown. The Potala Palace, which just completed the new floodlighting project in October this year, is welcoming the attention of the world with a brand new attitude. The project, implemented by Philips, the world leader in energy-efficient lighting, has stood on the "top of the world" in terms of its energy-saving performance and the creation of richer lighting effects for buildings.

A model for energy saving in the plateau - reducing energy consumption by 50%

It is reported that this year Tibet will formulate and issue the "Design Standard for Energy Efficiency of Residential Buildings in Tibet Autonomous Region", and the new building will enforce the design standard of 50% energy saving. When energy conservation and emission reduction have become the basic policy of China's economic construction, the Potala Palace floodlighting project, which is the focus of the whole Tibet, is particularly eye-catching.

Because it is located in the plateau, the requirements for the strength and reliability of the lamps are much higher than those in the plains. Therefore, Philips Lighting uses a new type of floodlighting fixtures. This kind of luminaire is composed of high-strength die-cast aluminum lamp body, which is enough to resist the influence of external environment. At the same time, tempered glass, silicone rubber sealing ring and stainless steel protective net with thickness of 1.6mm-3mm are added for its stable work. Multiple "protection kills.

At the same time, this luminaire adopts a newly designed elliptical reflector. Therefore, the light output is more than twice that of the same ordinary luminaire, and it can be opened from the back, which provides more convenience for maintenance work such as replacing the bulb; it is reported that After the application of this luminaire, the total power consumption will be reduced to half of the ordinary luminaires, which is fully in line with the requirements of the “Tibet Autonomous Region Energy Efficiency Design Standards for Residential Buildings”, and is also the lighting energy saving for other buildings in the autonomous region. Provides a perfect example.

a “golden combination” that shapes beauty and hierarchy

The Potala Palace is a holy place in Tibet. At the same time, it is the center of the night illumination of Lhasa. At the beginning of the design of the lighting scheme, the Potala Palace Management Office hopes that the new floodlighting can be mastered and leveled, and through various lighting modes, creating architectural atmospheres of different seasons and perfectly reflecting the style of the building itself - these Requirements, through the new lighting up to seven different angles of light distribution settings, was fully satisfied.

In the implementation of the lighting scheme, the designer carefully arranged two effects: high beam effect and low beam effect. For the Red Palace in the middle of the Potala Palace, there are two modes of white light and yellow light that can be switched. The high beam is used to express the overall momentum of the building and the volume of the building. The low beam is used to express the details and layers of the building. The low beam effect and the high beam effect can be simultaneously applied, and the atmosphere can be switched as needed, and can be lit simultaneously at major festivals.

In the summer, as the center of the Potala Palace complex, the Red Palace can choose high-color white light to create a bright atmosphere, a clear atmosphere in the summer night and a close-knit feeling; in winter, you can use partial The golden light is set off. Expressing the brilliant momentum of the Potala Palace in the snowy plateau. As the seasons change, the phases change and set off each other, which also expresses the beauty and harmony between architecture and nature.
