COB led tube light is to break out?cob, t5, t8, tubes, led, lights, lamps, lighting, fluorescent, bulbs, reviews: GGII survey data show that in 2017, COB will account for about 15% LED lighting package in the field of value, it has a large market in the commercial lighting. The COB after nearly six years of development, the advantages of LED lighting in the area revealed beyond doubt.GGII survey data show that in 2017, COB will account for about 15% LED lighting package in the field of value, it has a large market in the commercial lighting. The COB after nearly six years of development, the advantages of LED lighting in the area revealed beyond doubt. ? wanban with TCOB “helm” stone super engineering technology research and development managers believe, COB development currently experiencing some bottlenecks, COB on some controversial topics, hidden in between some of the “non-public secret,” it is time opened.LED development all the way forward, from the initial functional requirements to the present but also the pursuit of light quality and design aesthetics, COB emerged. But COB facing diverse size, power-free standard, drive power requirements higher difficulties, and this series is difficult to set a standard, affecting the degree of automation popularity COB, and the popularity of automation and directly restricts the development of the COB.In fact, from the lighting to the home office lighting, from super light to industrial lighting, COB can try and provide intelligent support. COB applications so there is room for imagination, the application should also pay attention to some details. “For example, the degree of thermal grease coating thickness, application of snap kit, LED components can not touch other aspects, engineering and technical personnel need to communicate with customers carefully.” Stone super summary from the ordinary course of communication with customers in contact the COB application process issues that need attention.High-quality lighting can create a very comfortable and pleasant environment, while better display merchandise. COB lighting solutions using the COB technology to maximize the characteristics, can fully meet the supermarkets, the diverse needs of office lighting, restaurants, hotels and other different applications. wanban Opto-electronic (300219.SZ) Jiao Qi senior product manager, the quality of light affect the COB has five factors, namely: Rf & Rg double index, the standard color reference light source, colorimetry and color distortion icon.However, a good quality of the light source lamp is not just better, matching the reflector cup, power supply, etc. will also have an impact on the lamp light, life and so on. To COB achieve better lighting effects, select the secondary optics is very important.General Manager Zhang pointed out that the effect of the lens is no vice squad light, light shape more beautiful, if design is the use of TIR, the light extraction efficiency is relatively high. Different applications for secondary optics have different choices and requirements, “such as wall lights, will be greater use of reflective glass.” Zhang Xiong said secondary optics also need to meet the requirements of designers, achieve their like effect. He believes that “no secondary optics must be the best suitable is the best.”Technical problems to solve, resolve optics, optical efficiency can be guaranteed, the next it is to solve the reliability, stability and longevity issues.Now increasingly demanding LED lighting, no flicker is high frequency words appear. ? How to achieve it without stroboscopic Shenzhen Deli & P Po Cheng, director of product made, there are several programs to solve: Passive PFC + valley fill circuit; two-stage program, active PFC correction + DC-DC constant current circuit; no correction PFC the BUCK circuit; LED DC power supply ripple to end the series (no flash) dedicated IC; LED power supply DC terminal linear constant current series circuit. “At the same time, doing the foreign market, paying particular attention to the different requirements of different national markets voltages.” Po Cheng expressed.Precisely because COB applications have imagination in the application there will be many issues to note. “For example, the degree of thermal grease coating thickness, application of snap kit, LED components can not touch, and many other aspects,” in wanban engineering technology research and development manager for Stone ultra opinion, these details are needed R & D engineers and application the multi-client communication.LED development all the way forward, from the initial functional requirements to the current pursuit of light quality and design more beautiful, not just the light source is required, and requires a light source, secondary optics, drive the overall layout of the power line.From this point of view, COB outbreak has been no turning back.
