Modularity is not a new issue. It has been raised very early and accepted by many people in the industry. Why is the speed and extent of advancement not meeting expectations? Between the similar products of different manufacturers, there are often embarrassing situations that are difficult to communicate with each other, and the consumer use process will also cause a lot of inconvenience. To this end, the author interviewed Mr. Zhu Mudao, deputy secretary general of the Taiwan Optoelectronics Semiconductor Industry Association. What is the significance of LED modularity? The development of the LED industry has been encouraged and supported by the government, but there are no relevant industry standards. Manufacturers have their own ideas and there will be many different modules. Under such circumstances, the development of a modular LED technology or standard is a very pressing issue for the LED industry. First, for the entire industry, standards can be established, there are rules to follow, avoid vicious competition, and promote healthy and orderly development of the industry. Second, it can reduce the risk of LED manufacturers development, because it is more uniform in specifications and can be solved. Cost waste caused by product specifications and dimensions; Third, for LED systems, it can increase its added value, solve the compatibility problem of component interchange of luminaire manufacturers, and reduce unnecessary waste in new product design. . Light thunder does not rain, what is the reason? The topic of modularization has been discussed for a long time, but even today, there is no consensus on whether to establish market demand or the needs of downstream manufacturers. This is a very important reason. To achieve modularity, LEDs must be aware of the real needs of luminaires and downstream manufacturers, determine the standards, specifications, and business models for manufacturers and markets. This is the basis for modularity. In addition, light efficiency is also a serious problem. It is necessary to understand the requirements of product interface and structural design, and define LED modularity according to the demand surface and application surface. This requires communication between standard setters and lighting manufacturers. Combine the different needs of the market and customers, find a balance point and explore the appropriate LED modules. Relatively speaking, this process is much more complicated and much more difficult. Fairness and interests, what are the priorities? At present, some of the larger manufacturers are leading the way in doing this. They have invested more in this area in the past, and they have a better understanding of the value of modularity for them and better control of the entire market. From an industry perspective, they can dominate the direction of LED modularization, and other small factories can only follow. From the current industry point of view, if the big factory dominates the modularization, it will hide the problems of technology, utilitarianism and patent restriction. If the patent can be released, it will not be a bad thing to be led by the big factory. From a market perspective, the market can, and should, change the situation and even develop a new game rule. There are many issues of interest involved, which will favor the big factory to be detrimental to the situation of small factories. Therefore, it is better to have this work done by research institutions and reach a consensus. Some associations are also promoting this. Zhu Mudao believes that the realization of LED modularization needs to reflect its benefits through market behavior. For example, some of the street lamps made in Taiwan are modular. He believes that through market behavior and demand, the speed is still relatively slow, and it may be necessary to use more technology, research organization planning, to drive this market forward, this speed will be accelerated, and at the same time, this modular standard can be guaranteed. Fairness. In the end, Zhu Mudao concluded that this may be solved by the power of the government or the power of the market and by the people of the association. How to balance standards and personality? One big difference between an LED light source and a conventional light source is that it can be arbitrarily designed, and modularity needs to be built on some or even a series of standards. How should the two balance? Zhu Mudao believes that LED itself can be modularized and can be arbitrarily designed. There is no direct contradiction between the two, mainly because enterprises should distinguish themselves from their own positioning. LED modularity has great advantages in terms of cost reduction and interchangeability, which is advantageous for general manufacturers. On the other hand, differentiated products are more individualistic, more reliable, better in performance, and relatively more costly. Diversified markets will naturally distinguish them. Therefore, I personally think that modularity does not mean that it cannot be arbitrarily designed, but that the cost of arbitrary design is relatively high, so that the market will play a balanced role for those who are willing to do this. Enterprises can be positioned according to market demand, and even diversified or full product lines are possible. Modular future development trend Intelligent lighting is the trend of LED development in the future. LED modularization also needs to move closer to this direction to explore an LED module suitable for intelligent lighting. In the future, the color temperature of intelligent lighting can be changed according to the changes of the environment, and psychologically matched with people to create a comfortable environment, which is an important part of intelligent lighting. Under these conditions, LED modularization needs to have several conditions: First, its own characteristics should be stable and high reliability; Second, the light color adjustable function, larger adjustable space; Third, he To have an integrated drive circuit, you can do interoperability between companies, and from these aspects, we can also see some directions in which technology needs to work hard. Intelligent lighting is not only a function of lighting, but also can do other things, such as reflecting the needs of an environment, sensing the perception of the human body, and doing some specific work. There is also the so-called communication function to do the work of environmental positioning. Future smart lighting will implement some functions step by step. Modularity is a problem that everyone cares about. Because of the rapid development of the LED industry, in fact, the interoperability between many manufacturers is very poor, and the market urgently needs to accelerate the pace of LED modularization. Different unit associations and even companies can cooperate and coordinate to explore a more appropriate LED modular standard. The performance of LED lighting varies greatly, the process manufacturing is different, and the price difference is also very large. These require a market specification to define and distinguish, and realize LED modularization on this basis. This process needs to be intervened by some industry associations, non-profit organizations or government agencies to restrict or even lead, in order to ensure its fairness and ensure the healthy development of the market.
