LED detonated the third light source revolution to replace the traditional lighting boom

After incandescent lamps and fluorescent lamps, LEDs detonated the third revolution of light sources, and the world has set off a wave of LED lighting to replace traditional lighting. According to LEDinside, the global lighting market will reach 82.1 billion US dollars in 2015, of which the LED lighting market will reach 25.7 billion US dollars and the market penetration rate will be 31%.

Industry development, standards first. Standards have become the key to winning this LED light source revolution. The standardization and specificization of LED lighting standard optical components are quietly sweeping the entire lighting market, detonating the industrial revolution of LED product middleware, setting off a new wave of product standardization. .

LED industry middleware standardization, the general trend

With the rapid development of the LED industry, the upstream chip and component packaging will enter mass production, and its products will be gradually standardized according to the characteristics of downstream application products. The module technology will gradually become standardized, and the integration and development of the mid-stream and downstream industries will accelerate. The upgrade will be gradually optimized.

Just as the PC industry is developing industry standards and developing related applications with modular and standardized concepts, the LED lighting application market will continue to develop towards common and interchangeable standards. LED lighting fixtures can also be upgraded or upgraded through standardized interfaces. The replacement application mechanism, instead of the design type of the current luminaire, can only choose to discard the entire light source device when the drive circuit or the light source fails, and it is difficult to achieve effective replacement and universality.

Despite this, the reality of interchangeability standards in the LED industry is not as smooth as expected. "At this stage, some LED companies are reluctant to adopt interchangeable standards on a large scale." Vice Minister of Technology Standards Department of the Joint Innovation Center of the Semiconductor Lighting Industry of Guangdong Province said, "The reason is mainly because some LED companies have exchange standards. Certain misunderstandings, they believe that the interchangeability standard has curbed the individualized, diversified innovation and development of LED products, increased the manufacturing cost of enterprises, and the interchangeability standards are too many, incompatible with each other, no choice, no mandatory standards. "In fact, the interchangeability standards mainly stipulate the technical specifications of the LED product interface specifications and the optomechanical heat and other aspects, and leave room for the diversified development of the technology and the personalized design of the products.

In the view of the motor, the current LED lighting industry in China is in the stage of transition from maturity to maturity. According to the status quo of industrial development, the stage of formulating mature interchangeability standards has not yet been reached. To promote the maturity of the industry, it is necessary to formulate process products ( That is, the industrial middleware) interchangeability standard, whereby the standard object of the LED lighting standard optical component can be determined, that is, the key components, components and application products of the LED subdivision manufacturing industry chain functioning as photoelectric conversion.

Standard light components: an innovative revolution in LED middleware

“What do LED lighting standard optical components do?” The industry replied: “To create a basic standardization system that promotes process product compatibility standards, this is the core goal of LED lighting standard optical components.”

According to the reporter's understanding, most of the LED industry interchange standards are concentrated in a certain part of the LED industry chain. The same type of interchangeable standards are too many and incompatible in the same link, and the standard-setting rights are mainly in the few large enterprises that have not yet formed a monopoly. In the hands, the development of standards or norms still cannot keep up with the speed of development of the industry.

In response to the misunderstanding of the above interchangeability standards, the standard optical components were developed at the beginning, following the market rules of natural selection, using "product classification - product / specification collection - selection optimization - specification development - market selection - standard molding" The implementation idea is divided into six levels according to the component manufacturing process and the manufacturer's main business, component usage, and the buyer's main requirements, namely: level 0 chip/epitaxial, level 1 package device, level 2 light source module, level 3 lighting module, level 4 integrated lamp, level 5 lighting system. For each level, refer to the electronic industry standard specification to build a specification system, conduct product collection, and determine that the application has undergone qualification review, compliance testing, evaluation authorization, and registration and labeling sales. After the enterprise applies for the standard optical component certification, it encodes and analyzes the spectrum, and then applies the application benefit analysis. The specifications obtained after data collection and analysis can be used as the basis and reference for the formulation of interchangeability standards.

What is the value of LED lighting standard optical components for industrial development? Minister Ma concluded that "the goal of LED lighting standard optical components is to achieve the standardization of industrial middleware. Its value lies in: creating a benign competition platform, promoting the orderly development of the industry; and prompting the development of interchangeable standards in line with industrial development; Reasonable division of the industrial chain level helps to promote industry segmentation; promotes manufacturers to achieve product specialization, refinement, and large-scale development; promotes benign cooperation among enterprises, helps to optimize industrial resource allocation, etc. Its ultimate goal is to promote industry. Mature development, so that the LED industry enters maturity quickly and healthily."

Taking the standardization of middleware to seize the commanding heights of industry standards

After more than two years of development, LED standard optical components are sweeping the industry in an awesome way. It is reported that up to now, the Standard Optical Component Certification Committee has issued more than 30 standard optical component detailed specifications, more than 20 companies applying for standard optical component certification, and 6 enterprises authorized by the Joint Laboratory of Standard Optical Component Testing, Standard Optical Component Alliance. Nearly 200 members, standard optical components label sales of millions.

At the same time, the work of standard optical components has also been highly valued by the Guangdong Provincial Government and has been included in the province's major science and technology projects. Huang Ningsheng, director of the Science and Technology Department of Guangdong Province, said: "The next step is to continue to use the standard optical components as a promoter to organize the implementation of 'visible light communication technology and standard optical components' major scientific and technological projects, and strive to create new advantages in LED industry innovation drive development." He pointed out: "On the one hand, the provinces and cities will be used as a pilot area for standard optical components in Zhongshan and Foshan, speeding up the mass production and demonstration of standard optical components; on the other hand, the United Nations semiconductor lighting engineering R&D and industry The Alliance and the International Electrotechnical Commission and other organizations will promote the construction of LED integrated standardization demonstration zones, incorporate LED components and modules into IECQ standards, jointly build industrial research innovation and intellectual property integration development model, accelerate the internationalization of Guangdong LED industry, and enhance Guangdong LED The international influence of the industry."

In addition, Hunan, Fujian, Guangxi and many other provinces have launched LED lighting renovation projects, and actively learn from and adopt the Guangdong standardization construction model. The application range of standard optical components in China is gradually expanding.
