LED lighting applications need to comply with design standards

　　With the development of lighting technology and applications, content and standards also need to advance with the times. The revised standard will further strict energy efficiency indicators, additional indicators related to LED applications, settings and so on.

　　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 applications, the requirements to become an important basis for LPD limits of 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 will have the LPD value adjusted to greater value to make LPD value more in line with the trends and requirements of energy-saving. It will focus on how to reduce the LPD value of the existing building to expand the public buildings energy-saving type of room question the standard provisions.
