LED fluorescent tube long life, many home users favorite, of course, long-life LED fluorescent tube, then it will not be sent to the light over time, the quality is not consistent can do? Here, Merkel technology sales staff told us to measure the quality of light is a bad term, what is the light fades, the light fades means of its luminous flux, such as luminous flux after 1000 hours less than the original number, expressed as a percentage He called 1000 a small decline.From the results of the current experiment, the impact of bad light the wafer is divided into two categories: the first is a wafer of different materials lead to different attenuation, the most commonly used material for the Blu-ray wafer substrate of silicon carbide and sapphire, silicon carbide, general structural design a single electrode, its thermal effect is better, the sapphire is generally designed for dual electrode, difficult to export heat, poor thermal effects; the second is the size of the wafer, the wafer material is the same, the size of the gap between the different attenuation are also different.LED fluorescent tube light decay phosphor problemRealization of LED fluorescent tube variety, currently the most widely used one is the most mature by applying a layer of yellow phosphor on blue chips, so that mixing blue and yellow to white light, the phosphor material for LED Tube attenuation of great influence. Most mainstream market YAG phosphor is yttrium aluminum garnet phosphor, a silicate phosphor, nitride phosphor, and the blue LED chip has a phosphor LED fluorescent tube compared to accelerated aging effects, and phosphors for different vendors bad light is not the same degree of influence, which is closely related to the raw material component phosphor. Finest white phosphor materials that make LED lamp has changed a lot compared to peers in the attenuation control tube. LED fluorescent tube fluorescent light failure problems glueTraditional packaged LED fluorescent tube fluorescent plastic commonly used epoxy or silicone, after the results of the light fades experimental results, LED fluorescent tube life with silica gel powder with significantly longer than the epoxy resin. One reason is that with the above two methods than packaged as finished LED silicone epoxy anti-UV capability and silicone heat better than epoxy; but under the same conditions, with an initial luminance of silica gel powder than epoxy resin Blending is lower, the most important is the refractive index of silica gel (1.3-1.4) lower than that of the epoxy resin (1.5 or more), the initial high light efficiency is less than epoxy.Tubes led t5 t8 Lamp beads of various manufacturers or patches are not the same quality, light some small, we can use the traditional method: the same two products of the same batch, a contact point, calculated using the time points such as day 10 hours , 100 days is 1000 hours, and then with the other new lamps do comparison, we can see the light fades come. Gini lighting production Led lamp using a regular patch, light is small, normally can not see the light fades within a few months.
