Recently, the National Development and Reform Commission and other six ministries jointly issued a “semiconductor lighting energy industry planning, system elaborated during the” 12th Five-Year Development Goals of China’s LED industry, the main task of key projects led lighting china and support measures, explicitly promote LED lighting energy industry The average annual growth rate of about 30% of the output value reached 450 billion yuan in 2015, LED lighting applications reached 180 billion yuan.
As a major energy consumer, the proportion of the construction industry energy consumption of the country’s total energy consumption has been showing an upward trend. According to Zhang was introduced, the deputy chief engineer of the China Architecture Design and Research Institute, China’s building energy consumption and climate conditions similar countries compared to the much higher, in this one, the proportion of lighting energy consumption and considerable front. Therefore, LED lighting products led lighting china in the construction industry, especially in green building potential is very huge.
Starting from the selection of light sources and lighting control to save energy
Zhang was to participate in the Beijing office building energy saving, he found that some of the units in order to reduce energy consumption and fewer lights do not even turn on the lights. “Simply in order to achieve energy can not meet the requirements of the vision, this is a misunderstanding, and undesirable. Fact, the energy-saving lighting includes many aspects, concerned about the application of lamps, luminaires, matching accessories, can bring a wide range of energy-saving space.”
Lighting system energy quantitative criteria, the most important is the lighting power density value can not exceed the standard value. Focus on selection of the light source with high luminous efficiency, low power accessories and high efficiency rectifier power density value is even lower than the target level, carefully calculated, can be achieved in the selection. However, the the chosen efficiency in the design and then, if not properly controlled energy-saving effect will be greatly reduced. The existing lighting control mode single-lamp control, multi-lamp control a variety of building automation system control led lighting china and intelligent control, intelligent lighting control system is set up in many engineering.
For some particularly large buildings such as pavilions, rely on manual control efficiency is low, intelligent lighting control, lighting on or off set by the program, the efficiency is much higher than the artificial time. Despite the increase in one-time investment, but the long-term energy-saving effect can costs be recovered in a few years, users will get the long-term interests of the return of the entire life cycle of the building. “Of course, in terms of the gas discharge lamp, when the to take motion detection control switch when the light source life impact of switching times larger switch time equivalent lit a few hours.” Zhang was to find a way to not switch the impact of the number of better light, Portable LED Explosion Proof Flood Lights is a good choice.
It is because of these reasons, LED architectural lighting increasingly attention. Example more use of LED outdoor lighting, including street lighting, garden lights lighting, aviation obstruction lighting, etc.. Power supply, external power supply, solar photovoltaic integrated power supply. Indoor lighting, used in more emergency evacuation lighting and instructions display areas for parking lot lighting for a number of lighting in offices, corridors, stairwells are not many, but also showing The trend of rapid growth.
