How to understand the LED flood light design guidance stadium light design teaching DIAlux simulation guidance standard material

Before a great lighting project is lit, it needs to go through a specific simulation program to design. So for the user, the solution provided by the supplier needs someone to help them understand the design, so that they can understand the designer’s intention. Read on to get an idea of entry-level lighting design.

1.0.1 formulation and principles for the purpose of this standard is in the sports lighting design and construction experience, on the basis of absorbing the international advanced standard, unified lighting design standards and detection methods, improve the quality of sports lighting design, to ensure the use function of sports venues, and safety, advanced technology, reasonable economy, energy saving.

1.0.2 This article stipulates the scope of application of this Standard. According to actual application requirements, this standard applies to stadiums and gymnasiums of major sports events, including lighting design of stadiums and gymnasiums of new construction, expansion and reconstruction as well as lighting detection of stadiums and gymnasiums.

1.0.3 Lighting design and testing of stadiums and gymnasiums shall comply with relevant international Lighting Commission (CIE) standards.It should also comply with international sports organizations such as GAISF, FIFA and IAAF.The requirements of television broadcasters such as The Olympic Broadcasting Service (OBS) and The Beijing Olympic Broadcasting Corporation (BOB) for events and their coverage.

With the construction of a large number of stadiums and gymnasiums gradually improved, lighting design should be carried out according to the actual needs during the construction of stadiums and gymnasiums, taking into account the full use of both during and after the games, so as to achieve both economic and practical purposes.In order to improve the efficiency of use, most stadiums and gymnasiums are multi-functional and multi-purpose, in addition to various sports, they can also be used for non-sports activities, such as concerts and other cultural activities.Large sports facilities can serve activities that accommodate large groups of people and thus benefit them economically.
