Why does the plastic tube led fluorescent lamp crack?
Led fluorescent lamps will generate heat, so heat dissipation must be done well. The best heat dissipation is that the outer shell is made of aluminum, and the led lamp beads should be mounted on the aluminum substrate to ensure good heat dissipation of the led lamp beads. Some people may ask, how do plastic tube LED fluorescent lamps and glass LED fluorescent lamps dissipate heat?
Here is a case where a customer visited Langte Company and asked a question. This customer has been using plastic tube led fluorescent lamps for a long time. He asked us if we could do it, and at the same time where we should use glue (plastic tubes should be glued together), and introduced that they use the glue imported from Japan-Dow Corning, which is said to be the top glue Up. Moreover, the LED tube is used in the freezer, and the temperature is extremely low. It stands to reason that there is no problem with heat dissipation, but what about the usage?
According to reports, after using the plastic LED tube for a period of time, it was found that there was a blocky foreign body in the tube, the plastic tube was cracked, and the plastic plug was cracked. Analyze the reason: because the plastic tube does not dissipate heat, the LED tube constantly generates heat when it is working, and the heat cannot be dissipated. One is that the tube is at a high temperature for a long time, and the plastic is aging quickly; the other is that the temperature in the tube is high and the strong hot air expansion will block the head. Rushing, causing the plug to crack, even the best glue is useless.
Therefore, practice has proved that plastic tube led fluorescent tube, glass led fluorescent tube are unreasonable led tube, the safest is aluminum-plastic led fluorescent tube, it is recommended that everyone pay attention when buying, do not go for cheap, cheap lights Tubes will bring safety hazards, remember! !
