LED lighting design must comply with the new standards

　　In recent years, with the continuous development of China's lighting technology, especially the growing applications of latest generation of LED light source in indoor and outdoor, coupled with the trend of energy saving requirements and the new demands put forward in building design standards, against this background, the standard formulation units - China Academy of Building Research also started consultation activities on the revision of this standard.

　　LPD is the lighting power density, is building a room or place lighting installed power per unit area, in units of watts / square meter. LPD values ??are key indicators of the evaluation of building energy efficiency provisions LPD limits in relation to the field of lighting energy saving, environmental protection, etc., will lead to a comprehensive lighting design considerations and taking into account the level of illumination, lighting, lighting quality and energy efficiency, the promotion is designed to promote the application of more efficient light sources, ballasts, lamps and other products. In practical application, the provisions of LPD limits become an important basis for the competent authorities, energy supervision department of the lighting design, installation, operation and maintenance of effective monitoring and management.

　　GB50034-2004 standards when a major change is to increase the office, residential, commercial, hotels, hospitals, schools and industrial buildings 108 kinds of Class 7 LPD maximum allowed value common room or place, in addition to residential buildings, the standard The other six categories of building LPD restrictions are mandatory standards, and this is the first lighting design standards on the history of our country.

　　The current global energy-saving environmental pressures gradually increase, meaning LPD values ??are more prominent. It is understood that the revised standard, LPD greater value may make adjustments to make LPD value is more in line with the trends and requirements of energy-saving, LPD will focus on how to reduce the value of the existing building, expanding public buildings type of room regulations and other issues.

　　It should be noted that the stipulation of LPD value and the further reduction may be a big challenge to lighting design. For example, in the real implementation of the standard, LPD value that can meet the energy saving requirements is often in conflict with the beauty decoration requirements of the buildings, which also became one of the most headache things of architects.
