LED LAMP TUBE STRUCTURE

摘要

An LED lamp tube structure comprises a tube body (1), a lamp head provided with conductive pins, a light source board (4) disposed inside the tube body (1), and a support rack (5) for supporting the light source board (4). The cross section of the support rack (5) is arc-shaped, the end face of the lamp head is opposite to the support rack (5 )and provided with a clipping hook (21a), the arc surface of the support rack (5) is provided with a clipping hole (51) corresponding to the clipping hook (21a). After the lamp head is assembled on the tube body (1), the clipping hook (21a) of the lamp head is clipped inside the clipping hole (51) of the support rack (5). The maximum external diameter of the lamp head is larger than the internal diameter of the tube body (1). The lamp head, the tube body, the light source board and the support rack can be connected together as the two ends of the support rack are clipped onto the lamp heads. Other parts of the LED lamp tube with two ends clipped with the lamp head can not axially move relative to the tube body, thereby the whole connection relation is reliable.
