[Source: Gaogong LED's "LED Good Products" November issue (Total 59) Wen|Xu Chaopeng] Why is the popular reflective glass in the field of COB light source, and now it is popular? Is the change in the basic characteristics of the two, or is the innovation brought about by the breakthrough of technology with COB light source?

According to the reporter, some time ago, due to the large luminous surface of the COB light source, the lens of the small angle was not good. Therefore, people in the industry thought of using a traditional reflector to pair, and after using the reflector, it can The angle of light is controlled within a relatively small range. But now with the advancement of COB light source technology, people can achieve high power on a small light-emitting surface, and at the same time have high concentration and high density of excellent characteristics. Therefore, COB lens products came into being.
“Before COB light source used reflectors, it was because the traditional lamps, such as metal halide lamps, were made with reflectors, so the industry colleagues made some minor changes on the original lamps and applied them to COB. The light source, in the form of a reflective cup, can also be closer to the illumination of the traditional light source, so it is more in line with the user's habits, so most companies at that time took the form of a reflective cup." Zhongshan Dalco Optics Co., Ltd. (hereinafter referred to as "Dalco" general manager Xiong Dazhang told reporters.
“But now the situation is that a small COB light source can achieve 30W. At the same time, we can make a single lens and make it very small angle. If the reflector is used, the size of the reflector is made. Limitations, the use of small angles will lead to a larger volume of the entire luminaire." Xiong Dazhang said that Dalco is now vigorously promoting the use of lenses for COB light sources, because the lens not only has advantages in improving the overall structure of the luminaire, but also luminous efficiency. It will be higher and can achieve the goal of getting more.
However, it is reported that the current accessories market for COB light source applications is still mostly reflective glasses, and the lens is also starting from last year, some relatively large parts manufacturers began to try, this year, there are many manufacturers in the scale of COB lens Production. Therefore, in the current domestic form, the COB source pairing is still mostly in the reflective cup, and the lens is in the process of updating.
"So, although the lensization of COB light source will be a necessity, it is only a trend. We can see that since this year, accessory companies have begun to slowly transition in this direction." Zhou Weihua said that other than this Lens products will have more advantages in export certification and safety inspection, and reflectors cannot be achieved in this respect. Therefore, based on various considerations, it will be a necessity for the future COB light source to become the main force in the market.
