After I’ve had my lunch, I’ve recovered some strength. Hall of Aurora is the key point of my visit, however, I’ve decided save the best for last. Skip the second floor I put my foot on the third floor, the exhibition on the third floor specialized in advertising lighting, commercial lighting, and household lighting. This area was much bigger than the ground floor, almost the same as a soccer field. As for the exhibitor of this hall, most of them were still from the Chinese mainland, after taking a look inside the hall I instantly understand the reason. If you have ever been to a Chinese lighting market in Beijing you will feel very familiar with it. Indeed, the appearance of the lamp is very important, some beautiful lamp was breathtaking. However the outlook of the lamp is very easy to simulate and the creative appearance will run out someday, so you must have some core technology to compete with other manufacturers.

After visiting a few boots, I have discovered there aren’t any exhibitors showing anything related to their technology such as CRI, to be honest, that is a little disappointing to me. So when I saw a manufacturer introduce CRI of their product I instantly decided to have a little chat with their salesman. The exhibitor came from Shenzhen and at the conspicuous place of their exhibition they put two same color boards irradiated by two different lights, one of the lights shows CRI95 and the other one shows CRI 80. As we know CRI represents the average value of R1-R15, and R9 (red) is the hardest to achieve, therefore it’s necessary to find out what value of R9. However, when I throw these questions to the staff of this company, the answer their response quite shocks me, all of them seem never heard of R9 value. After a while, one lady seems to be their manager told me the R9 value of their product is 10， anyone who has some common sense about CRI knew that if the CRI is 95, R9 can’t be just 10, it’s even just a simple math question. The unprofessional of their staff makes me highly adopt the quality of their product. but differ from other buyers I bring my portable spectrometry with me after I get a permit from their staff I have tested the light with my equipment, and the CRI of their light was surprisingly higher than I expect,  looks like they didn’t boast about their product. However, most of the buyers didn’t bring any equipment with them, if they heard such an unprofessional answer from sales, they might be walking away and that is such a loss for the exhibitor.

To be honest, I was a little disappointed after I meet such an unprofessional exhibitor, however, when you throughout the global LED market you could very easily find out the reason, high end LED market is still dominated by famous brands, most of the manufacturers that came from Chinese mainland still haven’t found out how to ascend to the ranks of the high-end manufacturer. As far as I am aware. Improving their R&D capability and uprise the professional level of their employee is the first thing they need to do if they wish to be at the top of the industry.

For me, the appearance of the lamp is not the only thing I’d like to see in the autumn edition, what I want to see is the dominator of the market, a high-end lighting manufacturer. After I found myself in the hall of Aurora, I realized I didn’t waste my time at all. There were some specified brands Such as Cree, Citizen, Seoul Semiconductor, and LUMILEDS（Philips), they are all of the most attractive exhibitors for me.

At Seoul Semiconductor, there was a new product called WICOP, it is an SMD without package and wire. WICOP with its small form factor provides market-leading color uniformity, is cost-saving at the fixture level with high lumen density, and allows design flexibility, it will very much help to reduce the number of LEDs and PCBs size. While common chips for high/mid-power go through multiple thermal interfaces between the chip, package, and PCB, WICOP enables excellent thermal characteristics with a direct thermal path to the PCB.
