[High School Annual Meeting] Mingwei Electronics Li Zhaohua: IC power makes landscape lighting and general lighting simple and clear

Mingwei Electronics has been working tirelessly for several years in linear IC power supply in Shenzhen. It has made great progress in the field of indoor lighting and outdoor lighting.

On the afternoon of December 22nd, the "High-tech domestic power supply ideally shines into reality" power supply in the 2017 High-tech LED Annual Conference officially kicked off.

In the first speech, Li Zhaohua, general manager of Mingwei Electronics, delivered a keynote speech titled “IC Power for Landscape Lighting and General Lighting.” In the speech, Mr. Li Zhaohua shared with the audience the changes that the linear IC solution brought to general lighting and landscape lighting.

LED general lighting has been spoken for many years. Whether it is in ordinary light source, indoors, home or outdoor, general lighting has been basically standardized from switching power supply to now, and even the concentration of customers has led some customers to face the choice of solutions. Great cost pressure.

For the lighting of the landscape, the state has given great support, including urban lighting and outdoor lighting. Especially in the building sector, the state will invest nearly 10 billion yuan in the local government every year, including in Shenzhen, Shenzhen will be close to 800-90 billion next year, which is in the urban lighting, especially the G20 summit, which are outdoor High-power power supply, outdoor intelligent RGB, including RGB, but our general-purpose lighting is also a thing that wants to become a situational type, but there are still some shortcomings at this time, so outdoor high-power I position it as outdoor, that is, landscape quantification Part of the main lighting, plus RGB, including RGB are the visual sense of urban lighting, which is divided into two categories.

At present, the general illumination source, like the 800 lumens bulb, functions as soon as it is on. Mr. Li Zhaohua said that at the annual meeting of senior workers three or four years ago, we are still discussing how to make the simplest things complete, and now that it has been mass-produced, it will go to the "Red Sea" stage. It may be more intense in 2018.

How to break through? Mr. Li Zhaohua said that the customer base is now concentrated, and the market is accelerating after the concentration. Today, we are now looking for ways to do versatility, including dimming. Li Zhaohua mentioned that there are many dimming schemes, and the linear scheme makes dimming easier. Li Zhaohua believes that with the change of time and the continuous requirements of customers, the corresponding two words can only be used to make the best dimming method with the least peripheral device, the least chip solution, and the most reliable verification. Big companies are focused on linear solutions.

In outdoor landscape lighting, especially in outdoor high power, still need simple words. What stage does the current linear technology develop? Mr. Li Zhaohua said that at this stage, many large companies are adopting linear solutions. On the 200 watt or even 300 watt solution, the efficiency of the Ming Microelectronics linear solution will exceed 93%.

And what will happen to Mingwei Electronics after the power boost? Li Zhaohua said that now Ming Microelectronics is implementing dimming and color grading in the study of outdoor field linear schemes. Nowadays, outdoor intelligent control interfaces are becoming easier and the solution is becoming more and more simple, which also saves the user's reliability requirements for power supply.

For intelligent lighting, Mr. Li Zhaohua said that he is optimistic. He believes that in 2018, intelligent lighting will start walking like a child. Nowadays, intelligent lighting is in its infancy. Once the application control APP is embedded in a shared platform such as Alibaba and WeChat, I believe that intelligent lighting will truly enter our environment.
