How to make the LED tube? Introduction of LED tube: LED tube is also commonly known as LED light tube, LED fluorescent tube, LED fluorescent tube, and its light source uses LED as the luminous body. The traditional fluorescent tube is also called a fluorescent lamp. There is a filament at both ends of the lamp. The tube is filled with traces of argon and thin mercury vapor. The inner wall of the tube is coated with fluorescent powder. The gas between the two filaments emits ultraviolet rays when conductive. Make the phosphor emit visible light. Due to the heavy metal pollutant "mercury", the discarded fluorescent tubes pollute the environment very seriously. LED tubes use light-emitting diodes as light sources, which have higher luminous efficiency, more energy-saving, longer service life, and are more environmentally friendly. Become the most ideal product to replace the fluorescent tube at the current stage. The LED tube is the same as the traditional fluorescent lamp in terms of size and caliber. There are T5 tubes, T8 tubes, and T10 tubes, with lengths of 0.6m, 0.9m, 1.2m, 1.5m, 1.8m, and 2.4m. LED lampshade introduction: LED lampshades are basically 1/2 aluminum alloy + 1/2PC cover, and basically no glass cover is used. The PC cover is roughly divided into the following types: transparent cover, transparent striped cover, diffused striped cover, and milky white diffused cover. 1. Transparent cover: As the name suggests, the transparent cover is a transparent PC cover. The lamp tube made of this cover can see the lamp beads, which is very dazzling and easily dizzy, and does not meet the human requirements for light. The light transmission performance is good, and the light transmission rate can reach 91%. 2. Transparent striped cover: This kind of cover is a semi-transparent cover, which can diffuse the light, but the light is not even enough and will not dazzle the eyes, and the light transmittance is about 88%. 3. Diffusion stripe cover: also known as thick stripe cover, the light transmittance of this shell is about 86%, the product made of this shell does not seem to have the feeling of dark areas, and the influence of dark areas is cleverly avoided. 4. Milky white diffuser cover: This cover is also used by most manufacturers in the market. The general light transmittance of this cover is 83-85%; the light transmittance below 83 is completely invisible to the light spot of the lamp beads. .
