The new value of LED in the world of sustainable development

What kind of light source is the body like light source? How can light change? What kind of lighting is needed at night? Home lighting is as long as enough light on it? PHILPS lighting research and development center, general manager of China Piet DERKS in 2012, Shanghai international new light source and new energy lighting Forum Report, the new value of LED in the world of sustainable development is about these issues. In his view, high-performance lighting, the first question is to be safe, second to energy conservation, the third is to be happy.

With the continuous progress of the times, the demand for lighting is changing. Modern people 50% to 80% of the time is spent indoors, will not be exposed to the sun, the modern people put forward higher demand for lighting. In this case, we need to use artificial light source to simulate the external light, the simulation is good, can make indoor lighting to achieve a healthy and comfortable effect. However, a wide variety of outdoor environment, snow cool, autumn to meet, warm evening, from this point of view, indoor lighting should also be considered from a variety of possible simulation of nature.

Different places have different requirements for classroom lighting, the need to ensure that the light can make them healthier, to improve their learning effect; if the hospital can successfully simulate the external environment, can ensure the sleep time and quality of patients; the mall needs proper lighting design, to provide people's shopping experience; then the whole city the scenery with good lighting, you can enhance the image of the city.

Lighting is so important, how can we find an appropriate solution to meet the above requirements? We should use what kind of technology, but also to combine lighting and other systems? In addition to the application of intelligent light control, in order to better reduce energy consumption? Piet DERKS believes that LED is a key to solve the above problem, LED through the distribution of light and design, you can improve the entire ceiling of the light projection, but also can save energy.

In addition, a lot of places where no one is still lighting, especially in the neighborhood, so that the lighting is necessary? We should have a better design to make sure that it is only when people need it. We clearly need to design better, so that on the one hand, people activities have good visibility, but on the other hand they have such good results, but also to the lighting according to what people need a way to lighting, rather than the kind of intervention, intervention, the nature of light pollution lighting. LED equipped with intelligent lighting control system can meet these requirements, people usually have a variety of views on LED lighting, but in such an environment with the same LED, but can achieve a 70% satisfaction rate.

With the development of the times, people increase in space in the indoor environment, lighting of city influence on nature and then gradually increased, LED is also increasingly showing greater lighting advantages, more in line with the new requirements of all the world's sustainable development. However, the development trend of lighting is not simply a transition from incandescent to LED, we also need to do a lot of work, such as improving the quality of lighting LED, with intelligent control systems, etc.. In addition, international organizations are also concerned about the development of standards, hoping to improve the quality of LED through standardization, reduce people's negative impression on LED.
