Plastic tube and glass tube does not heat well
It is extremely important to handle the heat dissipation of the led lamp tube, which is related to the extremely safe life of the led lamp tube. The reasons are explained from four aspects below. Poor heat dissipation treatment affects the life of the LED tube. Because the LED lamp tube converts part of the electric energy into visible light, other energy is converted into heat energy. The LED lamp has a small package area and less heat dissipation through convection and radiation. If the excess heat is not dissipated through the heat dissipation system, A large amount of heat will accumulate in the LED lamp, which will affect the life of the LED lamp tube.
When the temperature of the semiconductor element in the LED fluorescent tube rises, the electrical impedance will become smaller, and the electrical impedance will increase, which will cause the current to increase. The increase of the current will also cause the increase of heat. Such a cycle will cause the heat to be increased. More and more, and the phenomenon of lamp breakage is prone to occur. Thermal expansion causes bending of LED fluorescent tube parts. The material of each part is different, and the scale of thermal expansion and contraction is also different. When various materials are combined together, it is possible to cause the material to bend and expand, and the product will crack due to excessive stress at the joint. The materials used in led tubes are easy to oxidize. The higher the temperature, the faster the oxidation. If these materials are repeatedly subjected to high temperature oxidation, their life will be shortened. At the same time, repeated heating will cause the material to expand and contract many times, which will reduce the strength of the material, thereby destroying the material.
The heating of the LED tube will cause many problems, which will have a great impact on its life. Therefore, the heat dissipation technology of the LED tube is the key to the development and design. Plastic tubes and glass tubes cannot dissipate heat at all. The damage to the led tube is considerable. There is even danger.
Actual case: Coca-Cola customers use all-plastic tubes, sealed and installed in the refrigerator selling beverages, the temperature is only a few degrees low. After a period of time, it was discovered that the plastic tube was deformed, the plug was cracked, and the PC cover turned yellow. Analyze the reasons, the lamp tube is sealed and the heat cannot be dissipated, which leads to the aging of the plastic tube, the internal heat is large, the thermal pressure is generated, and the plug is broken. It is conceivable that the heat dissipation of glass tubes and plastic tubes is simply nonsense, so I advise you not to Greed for cheap, safety first.
