From the L1 to L2 post-lighting era to conceive a "super" transition

[Text / high-tech LED Xu Chaopeng] Since last year, the LED lighting industry has ushered in rapid development and huge market space, but at the same time the industry competition has become increasingly fierce, which has caused many manufacturers to lament that the reduction in profits cannot be avoided.

In order to gain new profit growth space, many companies have begun to try to break through in the field of subdivision. For example, intelligent lighting, automotive lighting, agricultural lighting, museum lighting, etc., while the economic benefits are significant, these subdivision lighting fields are also growing and growing.

Recently, Zhou Xuejun, Marketing Director of Lumileds Asia, proposed another feasible path for the development of the industry, that is, the change in form, LED manufacturers from L1 to L2 manufacturing and transformation, he is expected to become a kind of cost reduction and become Trends in the trend.

Zhou Xuejun defines, "L1 is a manufacturer of low-to-high-power LEDs, CSP LEDs, and color LED packages, while L2 is mostly classified as a DOB LED manufacturer."

Among them, the DOB is the Driver on board technology mentioned on the market. It is to arrange the LED light source and the driving circuit on the same substrate. Because the HV-LED can connect the light source in series with the mains, the LED driving circuit can be made. The number of parts can be reduced, saving space and saving costs. For example, the Acrich technology of Seoul Semiconductor is represented by the high-voltage LED + segmented constant current IC driving mode.

According to Zhou Xuejun's judgment, it is easier for upstream L1 manufacturers to enter L2 market with customized products than L2 enters L1.

"The reason is mainly due to L1 manufacturers mastering the decision-making power of LED chip technology, voltage and color temperature. When L1 manufacturers enter the L2 manufacturing field, they can reduce costs and reduce the wasted lumen output by customized demand. LED lighting lumens The key to the difference in output is that better LED components can output lumens more efficiently than normal products," said Zhou Xuejun.

Zhou Xuejun said that if the minimum lumen output of an LED luminaire reaches 256 lumens, but the luminaire design only needs 250 lumens, it will result in 6 lumens output waste. At this point, if the L1 manufacturer takes over the L2 production, it can effectively control the waste situation and design a luminaire that fully meets the L2 utilization requirements.

“In addition, another advantage is that L1 manufacturers can tailor LEDs when they enter L2 production, providing greater flexibility, which will benefit downstream manufacturers and produce products that are more economical and more efficient.” Zhou Xuejun mentioned .

“It is expected that in the future, L2 products produced by customized specifications will be more and more in the North American market, Europe, Middle East and Africa (collectively referred to as EMEA) and South Asian Market (ASEAN), but such demand is still weak in China. Zhou Xuejun mentioned that in the future, only the compatibility between L1 and L2 products will become closer, which will enable midstream and upstream LED manufacturers to reduce production costs.

Moreover, Zhou Xuejun also mentioned that the emerging Internet of Things (IoT) industry in recent years will further stimulate the market demand for smart lighting products, especially the integration of higher-order lighting systems.

"In the future, the smallest controller will be the L2 stage product, because it is impossible to add many signals and controllers in the L1 phase, and the L2 luminaire IC driver is also likely to become a single luminaire control point. By joining like Microsoft or Cisco With an application interface such as (Cisco), L2 can be a complete lighting system," said Zhou Xuejun.

"According to Intel's forecast, from 2015 to 2020, there will be as many as 15 billion to 200 billion smart products on the market. One person will interact with 26 smart items on average." Zhou Xuejun finally mentioned that this will be a huge market.
