Abstract
A LED lamp tube which includes a hollow transparent tube, a LED lamp assembly disposed in the transparent tube, two conductive caps provided on both ends of the transparent tube respectively, and a circuit control unit. The circuit control unit includes a plurality of separated sub-portions. The respective sub-portions of the circuit control unit are distributed uniformly on the circuit board of the LED lamp assembly. Via the uniform arrangement of respective sub-portions of the circuit control unit, the heat within the LED lamp tube can be distributed uniformly, thereby lowering the temperature and facilitating the heat dissipation.
