A lamp tube is provided, including a cover, a heat sink, a reflecting structure, a light bar, and a driving circuit. The cover is joined with the heat sink to form a tube body. The heat sink includes a first portion and a second portion symmetrical to a reference plane. The reflecting structure is disposed above the second portion, wherein the reflecting structure and the second portion of the heat sink define a receiving space with the driving circuit disposed therein. The light bar is disposed on the first portion of the heat sink. |

1. A lamp tube, comprising:
a cover; a heat sink, joined with the cover to form a tube body extended along a first direction, wherein the heat sink includes a first portion and a second portion substantially symmetrical to a reference plane that is parallel to the first direction and intersects both the cover and the heat sink; a reflecting structure, disposed above the second portion of the heat sink, comprising:
a reflecting surface, tilted with respect to the reference plane at a first angle;a first extended wall, connected to a joint between the first and second portions; anda second extended wall, connected to an edge of the second portion that is distant from the first portion;wherein the reflecting structure and the second portion of the heat sink define a receiving space; a light bar, disposed on the first portion of the heat sink, wherein a normal line of the light bar is tilted with respect to the reference plane at a second angle; and a driving circuit, disposed in the receiving space. |
