LED lighting products reduce energy consumption
National Development and Reform Commission and other relevant departments recently jointly issued the "semiconductor lighting energy industry planning", in this plan systematically elaborated in China's "Twelfth Five-Year" period in the LED industry development goals, the main task, key projects and support measures other issues, specifically the promotion of energy-saving LED lighting industry output should be maintained at an average annual growth of around 30% in 2015 to reach 450 billion yuan, of which LED lighting applications account for 40% of the total proportion of the annual output value reached 180 billion yuan.
For some particularly large buildings such as pavilions, relying on manual control efficiency is relatively low, if the use of intelligent lighting control, the lighting on or off are set by the program, compared with artificial punctuality, efficiency is much higher. Although the one-time investment has increased, but the long-term cost saving effect can recover in a few years, the entire life cycle of the building where the user will get long-term benefits in return. Of course, in terms of gas discharge lamps, motion detection when taking control switch, lamp life greatly influenced by the number of switches, switch once the power is equivalent to lighting a few hours. To find a switch is not affected by the number of times a better light, LED is a good choice.
Energy-saving lighting systems are quantitative criteria, the most important is the lighting power density value can not exceed the standard value. Pay attention to choose a higher luminous efficiency of the light source, high efficiency low power accessories and a rectifier in terms of the selection, and then after careful calculation, the power density can reach values ??lower than the target level. But the choice of product design efficiency even higher, if not properly controlled will also make energy-saving effect greatly reduced. Existing lighting control with a single lamp control, multi-lamp control, building automation system control and intelligent control are a variety of intelligent lighting control system is set up in a number of projects.
It is because of these reasons, LED architectural lighting growing concern. At present, the use of LED outdoor lighting more examples, including street lighting, courtyard lighting, aviation obstruction lights lighting. On the power supply, external power supply, but also one solar photovoltaic power. In indoor lighting, used in emergency evacuation lighting and display areas indicate more, as well as for parking lot lighting, for lighting offices, corridors, stairwells of the current number is not much, but it is also showing a rapid growth trend.
