LED lighting products effectively reduce green building energy consumption

According to the China Architecture Design and Research Leader, at present the amount of energy in the building on a large part of the construction is higher than in other countries with similar climatic conditions. However, inside the building works, construction of the building just lighting a ranking of the relative proportion of energy front. So led street light wholesale products in the future development of the construction industry, the application potential, especially in green building is very huge.

National Development and Reform Commission and other relevant departments jointly recently issued the "semiconductor lighting energy industry planning" in this plan systematically expounded on China's "Twelfth Five-Year" period in the LED industry development goals, the main task, key projects and support measures other issues, specifically to promote 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 application products account for 40% of the total proportion of the annual output value reached 180 billion yuan.

Most of the use of energy-saving lamps depends

Beijing office building energy efficiency in the transformation of context, some places in order to reduce energy consumption and reduce or even turn on the lights turn off the lights. To save energy, but simply to reduce the role of light daily, this is a great idea misunderstanding, this does not meet our requirements for future development. In fact, in many ways, including energy-saving lighting, focus light, lamp, matching accessories of application, can bring a broad energy space, just as we can not save the same food to go on a diet because you want to save the food is the same reason. "

For some particularly large buildings such as pavilions, rely on manual control efficiency is relatively low, if the use of intelligent lighting control, the lighting on or off have been programmed than artificial time, efficiency is much higher. Despite the increase in one-time investment, but long-term energy savings in a few years to recover the cost to make, in the building where the entire life cycle of the long-term interests of users will get in return. Of course, in terms of the gas discharge lamp, when taking motion detection control switch, lamp life greatly influenced by the number of switches, switching power supply is equivalent to light up a few hours time. 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 the choice of a higher light-emitting efficiency, low power accessories and a high efficiency rectifiers in terms of the selection, and then carefully calculated to achieve a power density values even lower than the target level. But the choice of product design efficiency even higher, if not properly controlled also make energy savings greatly reduced. Existing lighting control with a single light control, multi-lamp control, building automation system control and a variety of intelligent control, intelligent lighting control system is set up in a number of projects.

It is for these reasons, LED architectural lighting growing concern. At present, the use of LED outdoor lighting more examples, including street lighting, garden lighting, aviation obstruction lights lighting. On the power supply, external power supply, but also one of the solar photovoltaic power. In indoor lighting, used in emergency evacuation lighting and display areas indicate more, as well as for parking lot lighting, lighting for offices, corridors, stairwells of the current number is not much, but it also showed a rapid growth trend.

LED lighting standards and technology needs further improvement

Architectural lighting standards in the country concerned, such as a series of norms, the lack of LED lighting standards. General interior and exterior of the building is used primarily for lighting requirements specific targets for the number of (illumination, light effect) lamps, lighting quality (evenness, color temperature, color rendering index, etc.), energy (LPD) and safety performance . China Architectural Design and Research Institute, deputy chief engineer Zhang was that the standards should cover the development of LED lights two ways: first, through the use of LED to gradually promote and improve the standard of preparation, so you can continue to the next step of promoting the technology and progress; the second is a series of experiences to draw promotion, and other designated foreign hands, then push to improve domestic standards. It is reported that, under the revision of the "architectural lighting design standards", will increase the content related to LED lighting, architectural lighting design to further promote the application of LED's.

Designation criteria alone is not enough, advances in technology and more is the top priority. "Just in terms of the optical characteristics of LED, long life, high efficiency, easy to control, low energy efficiency, rich colors, and security are areas that we want to see, but we also pay attention to some of the adverse effects of the LED, for example:. LED's point source, causing light concentration, peak intensity is high, easy to produce visual discomfort, LED color temperature is very wide, consistent control of the products in question, the continuous spectrum of the problem, not a continuous spectrum of human impact and so need further study. this is the future need to be carefully studied and overcome problems.

Innovation and quality lighting products for green building plays an important role

In the process of implementation of green building standards specified and popularity, there must be cooperation among institutions in the industry, to promote the use of new technologies. Another comes from the understanding of customer needs and the integration process of innovation and technology should pay attention to the problem is developing. In our practical experiments will be energy-efficient, mercury-free design, and innovative LED lead-free and other environmental goals together in the green building industry is undoubtedly the most worthy of study and research, which is located in Building 2, Philips Innovation Campus in Shanghai Philips Lighting office area GBU-LED sector is one of the best green building advertised works.

This project is to transform the old car plant, the building in the same building structure based on the transformation into a green office area. As a result of a full LED lighting system, the project has received buy led high bay lamps Gold certification. Throughout the stages of design inside, illuminating how the internal space with high ceilings, natural light and how to use the top of the plant and how it changes forms become the primary issue addressed in the project. Designers bold use of LED lighting, and lighting contrast monotonous traditional office area, hanging lamps and more custom lighting design is the biggest bright spot, combining various types of LED light sources, including LED PAR30, LED T8, LED MR16, LED modules. Clever use of circular lamps, with LED PAR30 light source as the basis for lighting office areas. Mezzanine office area using LED T8 hanging lamps, both the illumination and uniformity face full advantage of the design space. In the above plus a desk lamp, the finishing touch is both a design and completed the fill light function. Pantry and other seating area is full use of color, making the space becomes more vibrant.
