摘要

A lamp including the following elements is provided. A housing has an assembling opening and an electrical base on two ends thereof, wherein the housing has an inner wall and a portion of the inner wall adjacent to the assembling opening is an air-guiding wall. A cooling fan has a casing disposed at the assembling opening and forming an air channel, a fan wheel rotatably arranged in the air channel, and two partitioning boards between the air-guiding wall and the air channel so as to define two first air-guiding openings and a second air-guiding opening. A light-emitting module is arranged in the housing and opposite to the fan wheel. Accordingly, the present lamp does not require forming any air inlet or air outlet on the housing, and thus provides a simplifier structure.
