Is the tube of LED lamp all plastic tube well or half plastic half aluminium tube?
Of course, the power is placed inside the aluminum tube, so that the amount of LED heating plus the heating capacity of the power supply is considerable, because the power of this lamp is usually around 20W. If the power is bigger, half of the aluminum tube can not solve its heat dissipation problem. It also proposed another aluminum tube cooling fan: shaped tubes. The fan shaped aluminum frame with heat dissipation structure shape, greatly increasing the radiator area. It puts the power outside the tube so that the half of the aluminum shell is completely made into a radiator. Relative to the semicircular aluminum tube, its heat dissipation area has increased by more than 3 times. Coupled with the power does not put in the tube, but also to reduce heat, which greatly extended the life of LED.
All plastic tube is one of the most widely used early, because the main use of non isolated power supply, in order to avoid electric shock problems, so I hope to use more plastic tube. Which is used with Phi 5 straw hat tube LED. The fluorescent lamp is the biggest problem due to the heat radiating, all sealed in the tube, unable to escape, life is very serious, coupled with the straw tube had life is very short, less than 2000 hours on the bad.Semi plastic half aluminum LED fluorescent lamps sold on the market are basically the half PC Aluminum Alloy, in the half light of the use of plastic in need not pervious to light and need the half cooling on the use of Aluminum Alloy.

The power is placed in the aluminum tube, so that the amount of heat generated by the LED plus the heat output of the power supply is quite large, because the power of the lamp is usually around 20W. If the power is bigger, half of the aluminum tube can not solve its heat dissipation problem.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.
