The first "High-tech LED Lighting Exhibition", which is known as "leading the new trend of global LED lighting product design and application", was grandly opened at the Shanghai International Convention Center in China from August 30th to 31st, 2011. During the exhibition, Gaogong LED reporters conducted an exclusive interview with Dong Zonglei, the marketing director of Xu Rui Optoelectronics.
Xu Ming Optoelectronics' main shareholder Xu Ming Optoelectronics holds 49% of the shares, and the other 51% of the shares are jointly owned by six domestic companies including Guoxing Optoelectronics, Lang Boer and Shenghui Lighting. Although the same technical route as Xuming Optoelectronics, the difference between the two is that Xuming Optoelectronics looks at the global market, while Xu Rui Optoelectronics mainly serves the Chinese market. Xu Rui Optoelectronics has set up its production base in the mainland to facilitate the service of Chinese customers.
Xu Zonglei, director of marketing of Xurui Optoelectronics, said that 11 MOCVD equipments of the first phase of Xurui Optoelectronics have been commissioned, and all the production lines use 4-inch sapphire substrates. The production capacity is very considerable compared with the peers, 40mil, 45mil. Such high power chip capacity is 20KK/month. In addition, the overall yield of Xu Rui is relatively high, and the capacity utilization rate is relatively high. At the same time, Xurui Optoelectronics uses the sapphire substrate removal technology. After stripping, it is replaced with a copper substrate and the sapphire substrate is recycled. This also reduces the production cost of the LED.
As for the price fluctuation of LED chips on the market, Dong Zonglei revealed to the Gaogong LED reporter that the first thing Xuxu Optoelectronics needs to do is to improve the brightness of the LED itself and improve its quantum efficiency. In addition, by controlling the cost, the lumens per renminbi are reduced. In the production of every lumen, we use the cheapest price to give the market the most cost-effective chip. 
Many consumers are worried that the record of the driving recorder is not clear at night or in dim conditions,
so they are more inclined to buy a driving recorder with good night vision effect.
Here I want to popularize it for everyone. A high-resolution driving recorder does not necessarily have a good night vision effect.
The night vision effect depends more on the size of the aperture. The larger the aperture, the better the night vision effect.
Hikvision`s night vision driving recorder not only matches the high-definition resolution with a large aperture,
but also adopts advanced product development solutions, such as owl night vision technology,
to allow the Dash Cam to record in high-definition at night.dash cam night vision,night HD dash cam,HD night cam,night vision dash cam
