For most Chinese companies that still have confusion about the road ahead, what exactly is the standard component of LED lighting? Why do you want to be standard? What are the competitive advantages of optical components? As the leading unit in the development of LED standard light component level components in Guangdong Province, Jingke Electronics has participated in the development and formulation of many standards such as CSA and ZHAGA. Based on this, it has developed a series of indoor lighting optical components and solutions for the application of lighting manufacturers. Program.
In the online seminar on August 13th with the theme of “Standard Light Components Leading the Innovative Application Modelâ€, Zheng Yongsheng, Jingke Electronic Lighting Project Manager, solved many doubts for everyone.
What is a standard light component?
LED lighting standard optical components refer to the development of a unified standard digital standard for LED lighting components, each of which has specific optical interface data and middleware with specific unified coding standards. In fact, whether it is a component, a light engine, or an interface, it is a standardized definition of the four interfaces of light, machine, electricity and heat of existing products, and is applied to different application fields through different product forms.
At present, there are government and market levels involved in the development. The standard optical component is proposed by the Guangdong Joint Innovation Center (GSC), and the light engine is proposed by ZHAGA. It may also include new interfaces, such as communication interfaces.
Why do we want to be a standard light component?
This is the demand for the development of the entire market. It was first proposed by ZHAGA. About 200 companies participated in the joint definition of the standard product interface. Why do it, reason one: In traditional lamps, the products are similar, and customers can assemble products according to their needs. At present, LED lamps can't do this. For the downlight, except for the slight difference in the shape, the parameters are not much different, and more differences are reflected in the reliability, but this is difficult for the end customer to evaluate and discover. This is a dilemma in the development of the entire lighting market.
If the standard light components are defined, the customer can specify different brands of brackets, power supplies, light sources, etc. on the matching of the lamps. A simple selection and matching according to the application needs will increase the overall cost performance. At the same time, there is a standard for reference between users on the price comparison. The LED market is still a replacement market, so for a long time, we still need to separate some devices independently according to the traditional lighting practices, and make a standard interface, so that customers have the right choice and match. This is the only way for the development of the market.
In addition, from the perspective of the upstream, downstream and downstream enterprises, the current repeated investment is very high. If there is no standard for the upstream products, the enterprises in the application chain will encounter inconsistent interface dimensions when purchasing different brands of light sources, and the lighting design will be based on each company's products to invest in a new set of molds, such as heat dissipation or light distribution. Wait, this fee is very high. This adds to the cost of luminaire manufacturing to a certain extent.
From the point of view of market circulation, the current customer shipments are slow because the upstream technology update is too fast, so that everyone is afraid to prepare inventory. This has caused many manufacturers to dare to produce orders or orders when they are expected, and this cycle will drag on for a long time. If the upstream product can be standardized, no matter how the upstream light source is upgraded, as long as the interface is unchanged, the corresponding PCB and heat dissipation interface will not need to be changed, and the downstream enterprises can stock up in advance and improve the supply efficiency.
What are the current progress in the implementation of optical components, and what are the commonalities and differences between different organizations?
At present, the consensus of the entire industry must be pushed, so how to push how to push, and what kind of product form to push, here is the biggest competition. In the industry, ZHAGA is the world's first brand, they are pushing the engine; CSA is doing interface projects in the form of projects, Guangdong Province is the optical component in the form of standard optical components, and the Ministry of Industry and Information Technology is promoting LED industry standards and national standards.
At present, ZHAGA has standard application products from downlights to spotlights to lightbars and street lamps, and the overall controversy is relatively large. But in terms of its design ideas, in fact, everyone is recognized. At present, the situation of promotion in the world is relatively good. Several major manufacturers have many products, and the domestic progress due to the price/performance ratio is slow.
The standard optical components in Guangdong Province are different from ZHAGA, and put forward their own new ideas. According to the hierarchy, the industry chain has been newly combed: Hierarchy 0 refers to epitaxy and chip, level 1 refers to package components, and level 2 refers to illumination mode. Group, level 3 refers to the illumination source, level 4 refers to the integrated luminaire, and level 5 refers to the illumination system. This division is relatively more reasonable.
Jingke is currently working on the development of Level 1 to Level 3, and 3535 and 3014 are both in compliance with the standards and certified by the standard. At the same time, the series of ceiling lamps, HV series and downlights integrated with power supply, heat dissipation, lens, etc. have been favored and recognized by the market. CSA is mainly engaged in interface projects. Jingke Electronics also participates in the entire R&D process. It is hoped that the project results will be upgraded to industry standards. At present, the CSA016 street lamp module standard has been established as a national standard. The Ministry of Industry and Information Technology is doing the whole big industry standard and the scope is wider. There are market-led behaviors and government-led behaviors, and the differences are obvious.
But no matter which organization, they have begun to cooperate with each other and learn from each other, so there is no need to worry about whether there will be conflicts between standards in different organizations in the future. It only takes some time.
Who should do it and which level?
The future market development will not be as long as the current industrial chain, each factory is very mixed, but no features. The future may evolve into a few large factories, mainly focusing on brand and R&D, more companies becoming brand foundries, and others focusing on brands and channels, but not excluding some companies that focus on brands, R&D, and channels. Big factory. So who should do the optical components and which level to achieve, this controversy is great. At least one point, from the development of LED, LED has so much controversy and uncertainty, because the technology of LED upstream has not been developed.
Why traditional lamps give the impression that the overall industry shape is clear, because the technical development of traditional lamps has been completed. For example, buying lamps in the market, this year's purchase and next year's purchase are basically no difference in parameters and appearance, at most the price difference, this is related to our CPI. The overall technology of LED is still increasing and rapid. From the perspective of future development space, the improvement of upstream chip and packaging technology will lead to a fundamental change in the form of downstream products. For example, there may be no heat dissipation in the future. .
Therefore, the design of optical components should be combined with the upper, middle and lower reaches. It is necessary to listen to the downstream opinions as well as the upstream development trends. The entire product form should have a certain life cycle, which is not static. As a result, upstream technology affects downstream changes, and upstream of optical component products is more reasonable in the current period of time.
What are the benefits of standard optical components for the development of industry and enterprises?
In summary, 1) can reduce the repetitive R & D investment of downstream enterprises; 2) can speed up the circulation of the entire terminal. The interface is fixed, the downstream can do some inventory, improve the shipping efficiency; 3) the interchange and compatibility of components, can make the terminal customers more convenient to match and combine according to the application environment, improve product cost performance; 4) the existence of components allows the entire luminaire Maintenance becomes more convenient and reduces the burden on the original factory. 
What is the standard LED component?
With the rapid development of the LED industry, the concept of LED standard optical components or light engines has been heated and controversial in recent years. The topic of shuffling is no longer fashionable, and LED companies have already passed the era of single-handedly fighting. In the LED industry, the close cooperation between the middle and lower reaches, the birth of LED lighting standard optical components will set off a new model revolution in innovative lighting applications.
