IMPROVED LED LAMP TUBE STRUCTURE

摘要

An improved LED lamp tube structure includes a shell (6) and a PC cover (7). The shell (6) and a PC cover (7) can be fastened to each other to form a cavity (61). A circuit board (1) is disposed in the cavity (61). A plurality of LEDs (5) is mounted on the circuit board (1) and arranged in the longitudinal direction of the circuit board (1). Each of LEDs (5) has a light-emission angle. The PC cover (7) has an arc angle equal to the light-emission angle. Each of the LEDs (5) extends in a direction perpendicular to the longitudinal direction of the circuit board (1).
