Li Zhaohua, General Manager of Mingwei Electronics: Driving ICs to Meet the New Challenges of Lighting Situationalization

On June 10, 2018, the "2018 (16th) High-tech LED Industry Summit Forum" held by Gaogong LED was held at the Westin Hotel in Canton Fair. The forum was divided into three special sessions. Among them, in the "Supply Chain Power Line Intelligent Manufacturing and Product Intelligence Innovation" special session, Mingwei Electronics General Manager Li Zhaohua delivered a keynote speech entitled "Drive ICs to Meet the New Challenges of Lighting Situationalization". In the speech, Li Zhaohua on behalf of Ming Microelectronics showed unique understanding of traditional lighting, intelligent lighting and scene lighting, as well as future product ideas and specific actions in these three areas.

Tradition, intelligence and scene lighting in Ming Wei’s eyes

What is traditional lighting? Smart lighting? Scene lighting? Li Zhaohua first gave a simple definition: traditional lighting is a kind of light viewing angle, which is the distribution of black and white light and shadow. It is a single color containing multiple elements; intelligent lighting is an action that light can be “light at any time, no light at any time”. And this action is not only determined by the remote control; the scene lighting is the connection between "light" and "heart", which is the upgrade of intelligent lighting.

From the technical level analysis, we can more clearly see the characteristics and differences of each of the three. The operation of traditional lighting requires only a complete and feasible solution. It can be a large company from a small company, mechanized by batch. To achieve intelligent lighting, not only a solution, but also a complete system, including system manufacturers, power distribution, etc., to integrate the solution with the system, can be called intelligent lighting, and this is not a simple matter. As for the scene lighting, it is to maintain the requirements of intelligent lighting technology, while designing a "one level higher", professional lighting designers to design a lighting layout that meets the scene and people's inner feelings. "In short, on this platform we define three concepts, the first concept is an independent body; the second is the control body + system; the third is the light control body." Li Zhaohua said.

Tradition, intelligence and scenarios, how does this “lighting road” go?

In today's high popularity of smart technology, will traditional lighting be abandoned by enterprises? Li Zhaohua said that it will not. "For traditional lighting, we don't have to do it, we have to do it. And, Ming Microelectronics has to do more simplification." He made a clear statement.

So how to simplify? As we all know, the current driver ICs have the characteristics of full patch, automation, parallel application, and high reliability. However, a new product introduced by Mingwei emphasizes full voltage. "This is our 2199EK second-generation fully integrated wide voltage product, PF value of 0.7, full patch, constant lumen." Li Zhaohua introduced, "800 bulbs as an example, can be guaranteed at 110-120V input 800 lumens of luminous flux, and guaranteed that there will be no off state." More concise, more extreme, is Ming Microelectronics' attitude towards traditional lighting.

For intelligent lighting, Li Zhaohua said that enterprises must be proactive. Although the business is a simple component in the smart space, there are still some additional features to be done. How to make a simple circuit component into a fully detachable module while maintaining the property of adaptive current change is a preliminary result that Mingwei has completed. "We will release a new smart and most user-friendly smart application in July to make it more concise." Li Zhaohua said.

As for the scene lighting, Li Zhaohua believes that lighting design is the most critical part. If the technical effect can reach "the ear can be seen," it can be called the real scene lighting. But there is still a big challenge that is to improve system security, because the current system security strength is somewhat unsatisfactory. Li Zhaohua explained: "For example, an audio system can transmit information to the cloud, and it can eavesdrop on any of your activities, so this risk always exists."

The suitable lighting layout and robust safety system are the principles that Ming Microelectronics has always kept in mind during the development of the scene lighting. And we must first go to the integration, standardize the relevant details of the driver, and then join the module, APP development enterprise, in order to ensure more with less. Today, Mingwei has more and more layouts for scene lighting. "At present, all products of Mingwei Electronics support the situational style." Li Zhaohua finally said.
