cob lens brand, Chong Ming optical lens leading brand cob, cob lens

The concept of LED LED optical lens optical lens / reflector cup LED cold light source is mainly used for products concentrating the light guide. Depending on the angle of light emitted LED design with light curve, by increasing the optical reflection, reduce light loss and improve light efficiency (The set of non-spherical optical lens). and research and design based on user requirements. Are classified according to the type of high-power lamps cob lens, the lens can be divided lights, indoor light lens, cabinet light lens and so on. COB market competition, not just the price, is the technology to enhance competition. First, the light efficiency is low cob angle lens on the market most of the COB light effect between 100-110LM / W, while the other light source device can reach 160-180LM / W; secondly, high tolerance cob color lens, large quantities When production of many products on the market color consistency is not good, the same color temperature or color inside the same batch shipping high tolerance deviations. Last cob lens quality, reliability, material needs to be improved, since the continuation of the current COB package using the traditional package model, high thermal resistance, low sulfidation resistance, light and dead light phenomenon is prone to high density packaging, ceramics board easy to rattle, easy welding phenomena. COB lens looking good, preferred Dongguan City Chong Ming Optical Technology Co., Ltd! cob lens brand, Chong Ming optical lens leading brand cob, cob lens by the Dongguan City Chong Ming Optical Technology Limited.
