The lamp tube of LED lamp is full plastic lamp tube good or half plastic half aluminium tube good?
The whole plastic lamp tube mainly USES the non-isolated power source, in order to avoid the electric shock problem, so adopt the whole plastic lamp tube. It USES a phi 5 hat tube LED. The biggest problem is that the cooling problem, because all the heat sealed in tube, don't spread out, the light failure is severe, plus straw hat tube original life is very short, less than 2000 hours it broke. And half plastic and aluminum tube is the market sales of the LED fluorescent lamp is essentially the half PC alloy, in need of pervious to light the plastic, half without pervious to light and the need to adopt aluminum alloy heat dissipation of the half. The power is placed inside the aluminum tube, so the heat from the LED and the heat from the power supply is quite large, since the power of the lamp is usually around 20W. The power is larger, and the semi-aluminum tube doesn't solve the heat problem. Leds are English light emitting diode (LED), its basic structure is an electroluminescent semiconductor chip, silver white glue or adhesive curing to the bracket, and then use silver or gold wire connection chip and circuit board, and then sealed with epoxy resin around, protect the internal core, final installation of the shell, so the LED of the seismic performance is good. The area of application involves cell phones, lamps, electrical appliances and other household appliances and machinery production
And half plastic and aluminum tube is the market sales of the LED fluorescent lamp is essentially the half PC alloy, in need of pervious to light the plastic, half without pervious to light and the need to adopt aluminum alloy heat dissipation of the half. The power supply is, of course, in the aluminum tube, so the heat from the LED, plus the heat from the power source, is quite large because the power of the lamp is usually around 20W. The power is larger, and the semi-aluminum tube doesn't solve the heat problem. So another kind of aluminum tube structure is proposed: the fan bone aluminum tube. The fan bone aluminum tube adopts the cooling structure of the shape of the fan bone and greatly increases the area of the radiator. It places the power on the outside of the tube so that it can be completely made into a radiator. Its cooling area is at least three times larger than the semi-circular aluminum tube. Add the power to the tube and reduce the heat, which greatly extends the life of the LED.
The whole plastic lamp tube is the one of the most early application, because the main use is not isolated type power source, in order to avoid electric shock problem, so more want to adopt whole plastic lamp tube. It USES a phi 5 hat tube LED. The fluorescent lamp the biggest problem is that the cooling problem, because all the heat sealed in tube, don't spread out, the light failure is severe, plus straw hat tube original life is very short, less than 2000 hours it broke.
