Experts answer: Will the Indian LED market surpass the Chinese market?

Will the Indian LED market surpass the Chinese market?

CEO of MLSINDIAPvt.Ltd

Are you talking about the market or the amount? If it is revenue, of course not yet. As for the quantity, the current demand in the Indian market exceeds 80% from the government's bidding, and the private demand is just getting started.

CSP market positioning and technical differences at home and abroad, how do you see it?

EMG Core Chief Technology Officer

Due to the small size of CSP, closer to point light source, high current density, etc., it is mainly promoted in applications such as backlight and mobile phone flash. In lighting applications, CSP has just started, with the improvement of light efficiency, flip chip The realization of cost performance and the popularity of the installed placement equipment are believed to show advantages in certain lighting products.

At present, several foreign LED manufacturers have made great efforts in the development and promotion of CSP, and they are ahead of the domestic chip and packaging factory. However, this gap is not as big as the previous high-power LEDs. For example, Yimeixinguang and Dehao Runda have approached or overtaken the technical level of international manufacturers. Their CSP products have been shipped in batches. Market competitiveness.

After reading a lot of articles, you can be regarded as your loyal fans. Since this is the case, the questions must be of a certain standard. It is definitely not difficult for you. So, which LED driver is good?

Hometown Ming Energy Saving Technology Product Manager

Sorry, something happened last night, so I came back to my brother this morning. The answer to your question is simple. I am driving, so...? ? . Ok, we are serious.

Speaking of which factory is good, if you don't understand it wrong, I think maybe you want to ask which brand is good. If you want to ask this question, then I want to ask you first, what characteristics do you value the driver? Seeing your self-description is a siege lion. I have also done this position and know the difficulty of this work. On the one hand, we must be able to solve practical problems. On the one hand, we may have to face the purchase of some of the relationship households to take care of, and may face things that the boss imposes on you from time to time. And once the product goes wrong, you may be the best back cook object.

So, as far as my experience is concerned, you may not have a lot of autonomy when you choose to drive, especially in big companies. Having said that, let me give you an example. Maybe the driver you value is not to cause problems afterwards. If this is the case, it is recommended to choose those big brands, but unfortunately, the procurement will do this step. Enough, because you are a siege lion... so you have to go further.

For example, what product is this driver used for? What are the design requirements for this product? What are these requirements for the drive? How to set up acceptance criteria? If you say something wrong, if you break it, how can you pass these acceptance criteria?

If these problems are not solved, as a technician, I just recommend it to you, can you believe it?

Now that the owners are more and more professional, how should they better identify the needs of the owners?

Entrepreneurship design partner

The so-called owners are more and more professional is actually an illusion, just as consumers are more and more professional, patients are more and more professional, in fact, because this profession is not deep enough, outsiders listen to you to say so, learn from one to two. In fact, more often, Party A does not even know what he needs in the light. If the designer can't prompt, explain, and solve the problems of Party A from a more professional and deeper level, this profession will not become a professional. In order to meet Party A's needs, there are actually different natures. If it is a government project, political appeals, investment should not exceed budget, maintenance costs can be controlled, social focus will be brought, and business development may be the goal. The characteristics of the local parties at that time were fixed, so design is not an art activity at least not at the beginning.

Can you use " jargon" to explain what is healthy lighting, except for Blu-ray? First, to help us understand more correctly and completely, Erping also wants to install experts from ordinary people around me.

Director of the semiconductor institute

Health lighting should have the following characteristics: the light source is stable without stroboscopic light, and the light is suitable for no radiation.

First, the illumination/chromaticity of the illumination source is required to be stable, and the stroboscopic/chromatic strobe will bring a certain degree of visual and non-visual influence to the irradiated person;

Second, the illumination of the source is required to be appropriate. Here I used the word "suitable", mainly because the light source's light intensity and spectral requirements are different at different times and in different scenes. For example, in the evening, we need a stable non-glare source with low color temperature and low brightness. In applications such as work or study, we need a light environment with a slightly higher blue light (higher color temperature) and a suitable brightness to improve the exposure of the person. Mental concentration. In some special application scenarios, there are special requirements for the brightness and spectrum of healthy lighting, such as time difference adjustment lighting, evening worker lighting, polar deep sea lighting, pilot anti-glare lighting and so on.

At the same time, the healthy light source should also have no ultraviolet and electric radiation. Of course, the commonly used white LED light source has no radiation problem.

In summary, healthy lighting is not fixed spectrum and lighting, but designed according to application scenarios and functions. I believe that the real healthy lighting in the future is definitely a combination of "health" and "smart".

What is the current market situation for UV LEDs?

Ye Guoguang, Deputy General Manager of Guangdong Deli Photoelectric Co., Ltd.

The UV-A part is now hotter, because the market for ink printing curing is getting bigger and bigger, and now the hottest is the curing of 3D printing. Now there is a way to cure 3D printing, a kind of thermal curing of relatively rigid materials, one is Compared with the soft UV curing, the current UV-A technology is becoming more and more mature, the luminous flux area and intensity are getting larger and larger, and the UV curing has a tendency to come up later. This is also a great application for UV-A in the future. As for UV-C, it is still suffering from price and light efficiency. The trend of replacing mercury lamps with LEDs is not very mature. Only the light and bulk sterilization equipment uses UV-C LEDs. The others are still the world of mercury lamps, so UV -C LED still has a way to go.
