What are the selling points after LED lighting energy saving?

In the replacement of the LED lights just hit, wisdom lighting is surging, the industry is almost invariably said that LED smart lighting is the driving force of the next wave of lighting market development, lighting industry will undergo a major change in the ecology.

As a senior person of LED lighting on both sides of the Taiwan Strait, Prof. Xiao Hongqing of the Institute of Electrical Engineering of Taiwan University of Science and Technology offered advice and suggestions for the development of the LED industry in the Mainland, and made great contributions to the development of lighting on both sides of the Taiwan Strait. He analyzed the current status of the LED industry in depth, discussed the future development focus and the path of the Chinese LED industry. His forward-looking views and bold remarks provided a new reference for the industry.

LED lamps: light effect, light distribution and appearance must be a breakthrough

Facing the current roaring LED lighting market, Prof. Xiao believes that the entire LED market began in August 2013, and the three major indicators of LED lighting began to mature, namely:

Visual indicators: The color rendering index exceeds 80 or more;

Performance index: The luminous efficiency exceeds 170 lm/W;

Market indicators: The price/performance ratio reaches 200 lm/$.

Before that, the talk about the advent of LED lighting era is a gimmick, only a declaration, in order to recruit more capital investment in the market.

He pointed out that from 2014 onwards, the focus of the decisive battle in the future lies on the lighting fixtures, and the emphasis is on the improvement of the lighting efficiency, the beautification of the appearance, and the optimization of the light distribution design. At present, the optical design capability of LED lamps has been insufficient, which is the biggest concern of the LED industry.

Regarding innovation, he said that one of the innovations of the future is the innovation of luminaire modeling, and the other is the innovation of control functions. If we do not think out of the traditional paradox, it will be very difficult to bring the entire industry to the right path.

At present, the cost performance of LED lighting products is measured by how many lumens one dollar can buy, but this is not enough to reflect the light quality of the lamps and lanterns. It should be possible to purchase as much as one dollar as a quantitative evaluation parameter, so the cost of lighting The evaluation criteria also need to be amended.

Talking about the current market situation, Professor Xiao said that the biggest fatal injury in the industry is the vicious price competition. Blind prices will cause the entire market to go bankrupt. Therefore, the country needs to set the standard of quality very clearly. The product must meet basic conditions, there is no room for discount, and good products are allowed to enter consumers.

Healthy Lighting: The Next Step of Smart Lighting

What is the next step in energy conservation? Talking about health, Professor Xiao told reporters.

Professor Xiao first explained the difference between "smart lighting" and "smart lighting". He said that dimming is a part of intelligent lighting and it is a transitional stage. When combined with human visual needs, it combines sensing equipment. Electronic circuits, combined with all communication and control design, the overall lighting system can give a best light environment, meet the best visual needs and take into account energy efficiency, it is called intelligent lighting.

The intelligent control that everyone talks about now focuses on energy saving. Professor Xiao pointed out that LED itself is energy-saving and does not need to emphasize energy saving. When the basic light efficiency, cost performance and color rendering index are mature, the future will be real. What is the focus? It is necessary to talk about additional skills, talk about intelligent lighting and people-oriented health lighting, which is the focus of the next stage.

Therefore, the way to go in the future is to move from intelligence to intelligence. It will feel the emotions of people, feel the light environment, feel the entire demand, and automatically adjust to the lighting environment that meets the needs of the human body. This is true. Smart lighting.

When replacing the LED lights to replace the tide retreating, smart lighting is the LED industry's next profit growth point.

Cross-border innovation: There are promises

Some of the technologies used in the LED field have been developed quite maturely. For example, in the electronics, communications or semiconductor industries, how to apply these technologies to the LED industry for integration and innovation is a major challenge for the future development of smart lighting.

Professor Xiao believes that smart lighting will involve electronics, the Internet, the Internet of Things, control technology, and sensor technology. Future lighting control will also cut into optical communications. ZigBee Light Link, Wifi or Bluetooth is just a wireless transmission technology. Each has its own advantages. Everyone plays their own game, but how to apply them to lighting is a problem that we are all discussing this year.

Future lighting research will be cut into medicine, and the light will be tuned to the best state through medicine, ergonomic health lighting will be achieved, and imported into the controller to create dimming conditions, so innovation will become more than just The innovation in the power sector is also promising for innovation in the optical sector.

In a lighting control system, whether it is a hardware device, a control driver IC, an integrated circuit, or a software APP, or a sensor that is automatically attached to a luminaire, it will automatically sense human emotions and automatically achieve the function you want to achieve. This is The result of the development of truly healthy and intelligent lighting. Therefore, smart lighting has become a completely new field. It is the integration of the entire system. This will lead the entire construction industry to start thinking in a comprehensive way, stimulating the designer, the decoration industry, and the entire lighting industry. Therefore, LED industry should make efforts to do integration in different industries.

How does smart lighting interface with external smart devices? Professor Hsiao suggests that the entire lighting system can have a system interface that is most suitable for lighting. When it is connected to the outside, it is a standardized electrical signal format, including voltage, current, and control signal specifications. Interface with the connection.

He said that smart lighting is not only a circuit, not only a light source, but also a communication, as well as the concept of system integration. The functions of individual parts can be played at will, but it is necessary to standardize and integrate the middle interface standards. So the future of innovation is not just product design. One of the most important innovations is the interface.

Interface Standard Integration: China's LED industry wins only channel

China's LED production ranks first in the world, whether it is technology or application, if the interface is not integrated, there will never be a breakthrough. Professor Xiao said that in the future, patents, technologies, and intellectual property rights can all be used interchangeably. Only the interface specification is the most critical link in the future.

The integration of interface specifications requires the country to strongly dominate and go to common specifications. LED is the new starting line. The formulation of specifications is the only channel that China LED lighting can win in the world. As we all know, China is the world's largest LED producer and the largest market in the future. Products sold abroad can be done according to foreign standards, but if sold to China, they must be done according to Chinese standards.

He emphasized that the breakthrough of the LED industry in China lies in the integration of interfaces. The state should set a general direction on strategy and formulate an independent set of standards that suits China's development. It should not blindly follow the standards set by foreign organizations such as DOE and Zhaga. The key to the success of LED licensing is the development of interface specifications.

Professor Xiao said bluntly, the real and key core of the LED industry lies in the interface integration between the lighting module and the driver. At present, many units on both sides of the Taiwan Straits are setting standards, and many semiconductor lighting industry associations have also been established. But to tell the truth, to achieve a global lighting market competitiveness, their vision and direction need to be revised.
