COB light source lens wins the reflector into a future trend

Some time ago, because the light-emitting surface of the COB light source was very large, the lens with a small angle was not good. Therefore, people in the industry thought of pairing with a traditional reflector, and after using the reflector, it can control the angle of light. 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.

Previously, the COB light source used a reflector, 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 the COB source. At the same time, in the form of a reflective cup, it can also be closer to the illumination of the traditional light source, so it is more in line with the user's usage habits, so most companies at that time took the form of a reflective cup. But now the situation is that a small area of ​​COB light source can achieve 30W. At the same time, make a single lens that can be made at very small angles. If a reflector is used, due to the limitations of the size of the reflector, the use of a small angle will result in a larger volume of the entire fixture. "Xiong Zhang said that Dalco is now vigorously promoting the use of lenses for COB light sources. Because lenses not only have advantages in improving the overall structure of the lamps, but also the luminous efficiency will be higher, which can achieve the goal of multiple gains."

It is reported that the current accessories market for COB light source applications is still mostly reflective cups, 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 produce. 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. Although lensing of COB sources is a necessity, it is only a trend. We can see that since this year, accessory companies have begun to slowly transition in this direction. In addition, lens products will have 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.
