Lighting is essential for the quality of life of humans and other forms of life, especially for light-associated biological activities. Its availability and intensity directly affect the health of the ecosystem, so we need quality lighting to better protect our environment. First of all, we must remember that lighting runs by electricity, and its huge amount of energy consumption caused huge C02 emission. Therefore, lighting solutions for sustainability in our current life and environment need to aim at energy saving. LED technology offers a very good choice with higher luminous efficacy and longer lifespan than traditional lighting solutions. With LED lighting, we can enjoy better lighting quality and 20-40% energy savings without sacrificing the lighting quality at all. Secondly, awareness of lighting architecture should be raised. Good lighting should not only be able to meet the needs of human visual functions, but also achieve the desired aesthetics and safety requirements. We should pay more attention to the visual performance of different lighting technologies, such as control strategy, glare, lighting uniformity and color rendition, etc., to make sure the lighting architecture is comfortable, and that it meets the needs of the user. Finally, lighting should be natural and smart. We should try to use daylight more and enhance the natural sun lighting by using photovoltaic and glazing technologies. Smart and connected lighting solutions can bring more convenience and energy savings to our lives. Moreover, intelligent lighting control systems can monitor and adjust the lighting according to the changes of occupancy, activities and even weather, and get the most satisfactory results in terms of visual comfort and energy savings. In conclusion, lighting is becoming more and more important in our life. For sustainable development of the lighting industry, we need to pay great attention to technological advances, as well as environmental and energy saving.
