Japan Optical Industries TOYONIA YOLL HR series high density COB light ?? Japan Optical Industries TOYONIA officially launched YOLL HR (High Reliability) series of high-density COB light source, YOLL HR series COB independent source of product applications Japan (New Material Struetare "(NMS) technology to achieve a high density of small LES chip on LED COB packaging field leading level product advantages:?? 1, features: high brightness, low attenuation, low energy consumption, long life and strong products use antistatic ability. silicone encapsulation, environmentally friendly lead-free process product requirements 2, high brightness, light color consistency; 3, the light fades: zero light fades 1000 hours to do four, high-quality silicone glue package, low light decay, long life; 5 formal qualification chip, Nichia phosphors, quality assurance; 6, quality assurance, reasonable price, regular shopping, no inventory is generally 3-5 days delivery very timely source ?? COB main advantages: 1.? . astigmatism light, no dazzling glare. particles greater the power LED light source more dazzling light, not suitable for children home use, but the LED surface light source led light manufacturing process to solve the glare problem, use a broader, more secure. 2. High thermal conductivity, low light decay, long life, poor packaging technology led along II thermal design, led after the second welding radiator can not use a lot of heat quickly export led led lamp light fades fast finished .led surface light source using COB production process, eliminating the straw tube and patch lamp beads metal stents encapsulation mode, the chip mounted directly on the metal substrate with excellent thermal conductivity, thermal efficiency than light Bead led light to improve a few times, a significant reduction bad light led light, effectively ensuring the led lamp life. 3. light uniformity, no stain, no ghosting. single high-power LED light source is often used to improve the optical efficiency of the lens, which in turn increases the cost of the optical viewing angle smaller ; The use of multiple beads led lights light fixtures will be uneven and ghosting .led surface light source is the entire surface of the package, advanced technology led the perfect solution to the problem of uneven shade lamp beads, the entire surface of the light, uniform illumination light efficiency is good, is the future of energy-saving light indoor lighting choice. 4. stable performance, easy to assemble, easy to apply. combinations particle type led lamp beads into a lamp lighting the need for secondary welding reassembled the whole lamp, high cost, fault ? more, potentially significantly increased production costs; led the overall package molding surface light source to achieve the led lighting source, modular production, users do not need to use secondary processing, simple to use, can be directly applied to the entire light production suitable for a wide range of promotion. 5.Viewing no flicker, no UV band, green, energy saving more in line with demand!
