With the improvement of material and spiritual life, people nowadays have more demands to lighting. It is no longer just about lighting. Besides energy-saving, more and more people are using lights to create a harmonious, homey and comfortable environment.

Smart lighting is developed based on this concept. Different lighting can create different atmosphere. Romantic, relaxed, sparkling, enjoyable, and comfortable feelings can all be created by lights. If it is possible to control indoor lighting through digital systems, residents would have more lighting variations at their will.

The combination of lighting design and intelligent technology can fulfill many people’s dreams. Digital intelligent lighting is an important component of smart living. Experts predict that in the near future, smart lighting will replace ordinary lighting and become the industry mainstream.

A. In order to present different effects, smart lighting with traditional lights will need lots of lights, which increases costs. Moreover, it is difficult to integrate harmoniously with construction materials and interior design.
B. Smart lighting system is turned on and off constantly, which will increase the impact to lights and reduce their life time.
C. Current smart lighting systems only have regional lighting and timer functions. Color , setting and brightness control are not yet realized, so it is still far from our expectation.
D. Traditional lights, including incandescent lights, fluorescent lights and energy-saving lights, cannot be applied to digital control due to technical deficiencies. LED lighting can maintain lumen efficiency and light color parameter in a larger sink current range, so it can materialize digital control.
E. Because LED is mixing R, G, and B color through electronic control systems, or changing different colors in a rhythm to create a colorful and dynamic atmosphere. This effect is impossible with traditional lighting.
F. When chips are built in lighting, which reduce the thickness and weight of lights, and it successfully integrate lighting and construction materials. When lights are off, people even forget the existence of them, but they are also omnipresent.
G. Compared with traditional lights, new LED lights pack chips directly into circuit boards with cooler, which reduce size and cost and increase steadiness.

Issues in using LED as intelligent lighting system:

A. LED lighting is a new application of semiconductor electronic technology. Semiconductor and lighting industry need to cooperate and advance together.
B. LED lighting is an emerging industry. With inferior technology and lack of core competitiveness, some companies are lag behind the international market. In the price war, the market overlooks product R&D and limits the development of the whole industry.
C. Spiraling competition is a common issue in LED industry. To pursue low costs, brightness and stability are sacrificed and it affects the development of the industry.
D. Many LED manufacturers haven’t developed their own brands. As the industry and competition grow, this market is not far from restructuring.
E. LED digital lighting and lamps should be organic combinations. Only when it occurs, can it become a model to create a hands-on experience in a warm, elegant, or varied environment brought by LED smart lighting.

Semiconductor lighting has established brand new experience through special lighting, cosmopolitan night scenes, indoor decoration lighting and display engineering. Regarding color presentation, lighting control, environmental protection, and energy-saving, it has clear advantages over traditional neon lights, incandescent lights, tungsten-halogen lights, and fluorescent lights.

However, LED needs to cut the price and finds breakthroughs in high-end digital intelligent products to penetrate the general market and enhance application levels. In this process, LED lighting will gradually replace traditional lighting in high-end application areas. It would be meaningful to semiconductor lighting engineering industry. New digital lighting, combining of LED lighting and smart lighting, will be revolutionary to lighting and culture of our world.
