tube light bulbs
At the moment, the key to TCOB, cob, mcob LED chip technology development lies in substrate material and epiwafer growth technologies. In addition to common sapphire and silicon carbide (SiC) substrates in the LED tube light industry, zinc oxide (ZnO), gallium nitride (GaN) and other materials have also become a major research focus in the cob mcob tcob LED chip industry. Most companies on the market currently employ sapphire or SiC substrates in epitaxal growth to make wideband gap semiconductor GaN. However, the two substrates are very costly, with large international led tube light manufacturers completely monopolizing the sapphire and SiC markets. In contrast, It substrates cost less and can be made into larger substrates. By raising MOCVD utilization rates, crystal yield rates are also increased. Therefore, Chinese LED manufacturers espcially led tube light suppliers or factories aiming to penetrate international patent barriers should form partnerships with research institutes to develop a better substrates. .Still, the question remains as to why a facility manager or building owner would stick with tube-based fixtures if the fixture must be replaced in any case. The advantage to tubes is a simpler retrofit. But the US Department of Energy (DOE) continues to report that LED tubes trail the performance of integral, LED tube light fixtures, although the tubes are improving.Lin noted Wanban is becoming more of a software company to help it expand in the news. Wanban now employs 23 software engineers for every hardware engineer.high quaity t8 led tube led t8 tube 9.5w 3 5 years warranty cob tcob chips 3w to 22w t5 t8 led tube high quaity t8 led tube led t8 .LED tube lights made up 57% of the fixtures installed in 2016. While sales of fluorescent tube lighting remained strong during 2016, respondents indicated that 68% of the energy-efficient lighting fixtures they used during 2016 were solid-state lighting. Looking back over the past 3 years that¡¯s a growth of about 9% per year between 2014 and 2016.
