Different LED tubes are different from the light source and materials that determine different price and safety, and the LED tube has a built-in power supply, and the agency different decisions is different.Century Ruiguang Company Engineering Department Li Manager's current technical security issues related to LED tubes, for the type II anti-electric shock type, requires LED tube input contact to reinforce insulation resistance and electrical strength, many built-in power transformers and LED module aluminum substrate Improper installation, causing the test to pass. Or many companies use non-separated power supplies in order to save costs and power efficiency. Internal wiring is mainly linear and insulating thickness, mechanical damage, and insulating layer. The inside is basically can't be in contact with the lamp shell of the aluminum, and the insulation is enhanced. It is also necessary to avoid internal wires and power supply directly to contact the outer casing and prevent the wire from being broken. In terms of structure, it is necessary to prevent insulation of the lamp head, screw, and contact metal surface, and the corresponding lamp head plastic should be used to prevent melting. Since the screws of the LED tube are directly locked, they are required to pay attention to the creepage distance and electrical interval. The internal power supply and the aluminum housing are needed to be separated from the insulating sleeve to reach the power level. The lamp holder and the lamp body are relatively insulated to prevent leakage of the shell.Article Source: LED tube

　　Author ：Green earth– LED Strip Lights manufacturersNow LED lighting technology is increasingly mature, but the LED street base is on the heat transfer or heat dissipation problem, what we can take is still limited, so today Xiaobian should talk about the problem of choice for LED street lamp heat dissipation mode, hoping Help everyone.At present, the heat dissipation of the LED street base is mainly divided into natural convection heat, adding fan forced heat dissipation, heat pipe and circuit heat pipe heat dissipation, and the installation fan forced heat dissipation mode is relatively complicated and the reliability is relatively low, and heat pipe and circuit heat pipe heat The cost of the way is compared, and because the LED street lamp is often used outdoors, the heat dissipation surface is located on the side and the body type is limited, and these factors are too friendly for other two ways, but However, it is necessary to play air naturally, the advantages of the flow of the heat dissipation, so the LED streetlights should choose natural convection heat when selecting a heat dissipation method.

　　Author ：Green earth– LED Strip Lights manufacturersThe traditional LED street lamp design is paying attention to the number of LEDs, and it is not much for its heat dissipation effect, in fact, it is not right. In life, with the increase in the number of LEDs, the heat dissipation design is also required, and the traditional heat transfer means is conducted, convection, Radiation and phase change heat, so we have to solve problems on the issue.LED street lamp heat dissipation technology uses a heat-insulating board mode, because the copper plate is relatively thick, so it is not very convenient to use, and there is still a risk of dangerousness, if you encounter a typhoon, or the earthquake may be an uneasy factor, so now It is a needle heat dissipation technology.Such a technique makes the heat dissipation, so that the LED junction is lower than the ordinary heat sink at least 15 C, and has good waterproof performance, there is basically no uneasiness due to weight, so Xiao Bian also likes this. The lamp is easy to install.The heat dissipation method of the lamp holder can be divided into a variety of forms, heat pipes, circuit heat pipe heat dissipation, installed fan forced heat dissipation, natural convection heat, etc. Low, so smallIt is recommended to use natural convective heat to reduce, safe and low cost.
