This year, not any “killer” product has been occurred on the International Consumer Electronics Show (CES) of the U.S.A. However, some more subtle technology is becoming the cornerstone of the technology industry.

Here refers to the Intelligent Voice Assistant. For people, who concerned about the technology industry, the concept of Voice Assistant is not novel. The technology industry has been exploring the interconnect device and the centralized function of artificial intelligence for many years.

This year is different because we have seen many digital products of high quality. We have gone through the prototype product stage. You do not have to dig any more, what voice assistant can help you do. Now you have a lot of choices.

On the CES of this year, voice assistant, which can be seen everywhere in the exhibition hall is no longer a minority.

Shawn DuBravac, economist of Consumer Technology Association (CTA) said that currently word error rate is basically the same between machine and human. In other words, the probability that machine understands human language accurately is similar to that of human beings. In contrast, this error rate was as high as 23% in 2013. Technology is progressing rapidly.

On this year's CES, voice assistants have been used in cars, refrigerators, door locks and other products. From social perspective, the data collection behavior of these devices remains to be explored. However, from perspective of convenience, voice assistants are indeed excellent.

The next few years, the competition around voice assistant will rise to a new height, and the voice interface will become center of Internet life.

Many technology companies are developing voice assistant and using them for a variety of devices and systems. At least for now, touch screens and buttons will not disappear completely, but most of the basic features, such as lighting, air conditioning and music playing, will be completed through voice interface.

These devices can achieve the potentiality that we expected. Compared to previous years, we seem to have passed the important milestones. We will no longer need to distinguish between "smart" equipment and general equipment.

From perspective of current LED lighting industry, the future of LED intelligence will have three directions: the first is the integration of LED and other intelligent devices, such as smart medical, security, and new energy vehicles; the second is technology innovation of LED intelligent control, such as from the traditional switch to APP control and then to the integration of voice and artificial intelligence technology; the third is the combination of LED and new materials.

Lin Jiliang, CEO of Forest Lighting, said that the development stage of LED lighting in the past few years stayed more in the Retrofit (traditional lighting replacement) and Intergrated (lighting), and that the replaceable light source as well as the integrated lighting are currently mainstream markets.

Certainly, in the future there will be more innovations, combined with a wide variety of building materials. For example, the connection of the outdoor landscape lighting LED with all building materials and a wide range of materials, which has brought the architectural lighting and decorative design of landscape lighting numerous changes. In the future, residential lighting will have more and better opportunities.

However, Guan Yong, CEO of Yankon Lighting, holds the point that the technology revolution of LED lighting has just come to the mid-development stage. A new wave of technology revolution of “Internet of Things” and development of lighting industry will collide with each other and generate new opportunities.

On one hand, the requirements of LED dimming, color temperature adjustment and color adjustment were activated from the last year, bringing the second time replacement and upgrade of lighting products. If your lights are without color temperature adjustment, then they will be hard to be sold. Three years ago, only fluorescent lamps were replaced into LED, but when LED lighting replaced all the other lamps, the second upgrade opportunity appeared with it. That requires us to exploit.

On the other hand, lighting plus sensor plus control have brought hardware of lighting the second upgrade and replacement. Many companies are doing so, but the problem is that single products are not situational, so experience dependence will not be formed and the demand of these products will not grow rapidly as previous thought. However, this is exactly our chance, so in the long run it is still worth looking forward to.

But there are many difficulties: The technology is very complicated, resulting in the non-interconnection even if we have already posses the technology, and affecting the use universality. Light control has not formed the rigid demand of market. Besides, LED light source and lighting are digital products, in which LED will need to chase opportunities in the future.
