In recent years, the LED industry has emerged with new technologies and new solutions under the multiple demands of new demands and cost pressures. The emergence of the "de-powered" linear solution has made it possible for companies and individuals engaged in the research and development and production of LED power sources to feel "promising." However, "de-energization" has been a topic of debate since its appearance.
At this year's Hong Kong Autumn Light Show, Gaogong LED interviewed a number of power companies and packaging companies. Among them, small and medium-sized power companies including Kegu Power, Birda and Dark Energy said that although “de-energization†is a major trend, this solution is not mature enough at the technical level, and it can only be used in the low-end market. Applications, some high-end markets with high quality requirements are not suitable; and Zhuopu and Zhaochi energy-saving packaging companies believe that AC LED module technology is now mature, and in terms of manufacturing process convenience and cost. Both have a big advantage.
For this topic, Zhu Xihe, general manager of Shenzhen Xingguangbao Optoelectronics Technology Co., Ltd. (hereinafter referred to as “Xingguangbaoâ€) told Gaogong LED: “De-powering is not to remove the power supply. In fact, it is simple to improve the LED power supply through other special technologies. To remove some of the relatively large electrolytic capacitors and transformers in the power supply, simplify the circuit design and device, reduce the size, and combine the smaller part with the LED package to package it into a whole in an integrated manner."
At this stage, the LED industry has a lot of misunderstandings about “de-energizationâ€, especially the rejection and even suppression of “no power†products by some traditional power supply manufacturers, which has hindered the development of this innovative new technology to some extent. . These problems have made many companies who are committed to the "de-powered" program research feel helpless.
Zhu Xihe said that the first "de-energization" does not mean that the LED package does not require a power supply. In fact, some devices of the power supply are omitted. For example, the electrolytic capacitors and transformers of the power supply are omitted, so that the overall power supply scheme is simplified, and the power supply is simplified. AC-LED integrated with the LED light source package, this solution has no effect on the volume of the packaged product.
Secondly, manufacturers have introduced "de-energized" packaging products long ago. After several years of development, the current "de-energized" packaging products have matured. In recent years, various COB-type “de-energized†packaging products have appeared in the packaging industry, which has greatly improved the production efficiency of lighting manufacturers, and the cost has been reduced accordingly. Only in some specific application fields The technology needs to be upgraded.
In addition, the emergence of "de-powered" products does not mean that the power supply will not be needed in the future, and the power industry will disappear. In fact, the power industry and manufacturers have already started the research and development of "de-energized" power solutions, and the technical solutions have gradually matured.
In recent years, the “de-energization†program has developed rapidly in China, and a number of companies have followed the footsteps of international manufacturers. Among them, Xingguangbao has unique technical solutions and directions in the research and technological breakthrough of DOB light engine technology, and launched the DOB light engine series products for the current market situation. It is understood that as of now, Starlight has launched a multi-product series such as a circular light-emitting surface (Golden Bowl) light engine, integrated certified high-end light engine, 5054 large-scale light-emitting surface light engine, and 5054 large-scale light-emitting surface light engine.
After the launch of the 2017 (8th) High-tech LED Golden Globe Awards, Starlight Bao took the “DOB Light Engine†and actively participated in the selection. According to the relevant person in charge of Xingguangbao, this product is a new DOB product developed by Xingguangbao for high-power, large-wattage outdoor lighting users. The product has the following innovations and advantages:
1, can be directly connected to AC mains, input voltage AC85-300V;
2. Appearance patent design, waterproof grade IP65;
3, constant current accuracy <2%, high conversion efficiency >90%;
4. Power factor (PF) > 0.9;
5, anti-lightning surge 4KV, high voltage through the II class lamps require AC1750V;
6, with constant power adjustment function, with overvoltage, overcurrent, over temperature protection (bare spot does not die).
It is understood that this product is a high-power (200W) large light-emitting surface, flip-chip DOB light engine products, focusing on solving the problems of unstable DOP product power supply scheme, small voltage range and anti-lightning surge.
Since the launch of the Starlight DOB light engine product, it has maintained a record of zero customer complaints so far, which is called “the light source that never goes outâ€. In the "de-energized" packaging products, Starlight will continue to introduce other different fields of light engine products, and penetrate the "never-extinguishing light source" into various lighting fields.
When asked about how the Starlight DOB light engine will bring changes to the LED lighting market, Zhu Xihe performed very low-key. He said: "At present, it is still too early to talk about whether this product will bring changes to the market, but users will definitely appreciate its beauty when using our 'DOB Light Engine' product. The applicability and compatibility of different areas of the market, or the reliability and longevity of this product, users will be surprised by surprises."
Although the "de-energization" solution has many advantages such as low cost, simple circuit, convenient processing, high degree of automation, etc., and Starlight has made continuous breakthroughs in DOB light engine technology. However, Zhu Xihe still maintains a sober cognition that a successful entrepreneur should have.
"The 'de-energization' solution itself lacks electrolytic capacitors, resulting in low luminous efficiency, stroboscopic, increased heat of the packaged device itself, and a certain impact on the service life of the packaged product itself." Zhu Xihe told Gaogong LED . If these problems cannot be solved, then the “de-powering†solution will always be a trend. It will not be able to replace the traditional power supply, and it will not become the so-called future mainstream.
How far can the “de-powering†solution companies go, whether they can open up the market in the market, or the expedient choice, short-lived, depending on whether they have core technology and can continue to optimize and improve, and the future development of integration with traditional power sources the road.
Starlight is continuing to make progress in this regard.
