Intelligent Lighting Design of Humanized - Slurry Pumps ELM Series - Vertical slurry pump EVR-100R
With the social and economic development, lighting design has been gradually broken through the conventional illumination, uniformity index for the design concept, more emphasis is humanistic design, through the illumination of light, color temperature, color rendering of the comprehensive consideration to The perfect combination with the building, creating a good physical and psychological environment. We meet the German design firm has completed the lighting of an International Convention and Exhibition Centre, construction design process, the humanization of modern lighting design made some deep thinking. I use this the hope that membership in this article with lighting design to explore the electrical designer.
The International Convention and Exhibition Centre, a landmark for the city, along the foot of the building due to potential built into the main building (building area of about 12 million square meters), A Square (the main entrance of the building, construction area of about 350,000 square meters) and B Square (Descented, construction area of 200,000 square meters) of three parts, the main building is divided into areas of international conference and international exhibition of two parts, A, B Square, a subsidiary as part of the main building, usually as a large open-air exhibition venues, festivals can be used as large-scale song and dance performance spaces (in the Folk Song Festival held two large-scale international performance), performance may be the main building into the background screen. In the design process, space and movement through lighting changes, people in the process of gradually building into the construction of the Qui macro experience, and through detailed performance, improved emergency lighting system settings, advanced lighting control system that people appreciate the meticulous design of the human concern and caring.
First, the space lighting design:
Lighting, space design architecture mainly in maintaining coordination based on the use of lamp type, illuminance, color temperature change of the function to construct the space-separated.
From the outside, including the main building of the Convention and Exhibition Centre (HKCEC part), A Plaza, B Square three parts. One of the main building built on mountains, magnificent, covering about 30 000?, Its top elevation is 169 meters, with white tensioned membrane to form a inverted hibiscus flower shape, when the night comes, hundreds of its lumen halogen light gold The warm light transmission of light from the inside out, silhouetted against the night sky appear under the more pure and noble, the characteristics of the city flags; A Place in the north of the main building, elevation 91 m, B Square is located west of the main building, separated by very spectacular city Express Ring Road, the elevation of 69 meters. The main building and the A, B Square, high and low walls, set off each other, so the lighting design must address the three relations in space. Many now use a more square lighting design of new technologies, such as neon, LED, cathode tube or a laser beam, etc., but the Convention Center to highlight the main architectural lighting design, A, B Square, just a set off the effect, if you use too fancy lighting, will be submerged in the grand main building momentum, but also with the main building of the calm style of inconsistency, so not as good as back to nature, combined with warm colors and the courtyard lawn, LED lamp and a small underground cast light (to avoid uncomfortable visual stimuli, to light only in the bush, play the role of decorative green belt) form an illumination of not very high recreational facilities, so that the square quiet, simple but with elegance. When people place in them, to relax taut nerves, feel the night's quiet and peaceful, good on the green leaves of the main building play the role of supporting the flowers, the lower the illumination design also save energy.
Within the main building area is divided into an international conference and international exhibition of two parts, in consideration when designing the use of different color temperature to create a different atmosphere, meeting area using warm (3000K) express a warm atmosphere, exhibition areas using cold colors ( 4100K) to maintain the characteristics of sunlight. In the exhibition area in order to further highlight its distinctive steel roof shape on the roof with a 6000K color temperature, and lighting designed to increase illumination, making the building function and form in the distinctive.
