LED lighting product development need to indicate standards

　　With the development of lighting technology and applications , content 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 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.

　　The biggest change of standard GB50034-2004 is adding  108 kinds of Class 7 LPD maximum allowed value  into the office, residential , commercial , hotels , hospitals, schools and industrial buildings, such common rooms or places, 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 , as well as the value specified LPD may further reduce the lighting design , that will be a big challenge. For example, in the reality of the implementation of the standard , and meet the energy requirements of the building LPD value and achieve beautiful decorative requirements "  In the Chinese old saying, "It's impossible to have both fish and bear's paw ," This also became the architect of the most difficult thing .
