What is nano led tube?
Plastic nano LED tube refers to the LED lamp shell is made of plastic, the general material is PMMA, PC more, the LED light diffusion part is also made of plastic, using PC material, the general LED lamp holder plastic parts are ordinary adding diffusing agent The LED lamp holder made of PC material, transparent raw material PC material uses materials similar to PA, but this material has better heat dissipation. Ordinary pc plastic tubes are prone to yellowing and brittle after using for a long time, and heat dissipation is also a big flaw.
The thermal conductivity of plastics is generally about 0.14 to 0.34, which is a dielectric insulating material. The American Coolpolymer company developed thermally conductive plastics and established the first industrialized production line in 2000. It is used in the electrical and medical fields, aerospace, automotive, lighting, and notebook computers. Widely used, and then plastic companies in various countries have launched the production of thermally conductive plastics. To use plastic instead of aluminum to make the LED lamp housing, first of all, the selected plastic must have higher heat dissipation performance, that is, higher thermal conductivity and high strength. This is because the lamp shell does not have heat dissipation fins. In order to reduce the thermal resistance of the shell, a thin-walled shell is required. The selected plastic must have a high melting point, high modulus and high strength, and can withstand multiple high and low temperature cycle tests.
At present, there are three types of led fluorescent lamps on the market. Glass tube, half-plastic half-aluminum, all-plastic tube. Led fluorescent lamps are mainly used for indoor lighting applications. For example, office space, school. Shopping malls can be described as a wide range. Glass tubes are fragile, which is a fact that can never be changed. The cost of semi-plastic and semi-aluminum tubes is too high, and there is a risk of leakage. It is difficult to popularize.
