The down lamp structure comprises an outer barrel, a lens is arranged at the bottom end of the outer barrel, a cavity used for containing and installing a lamp panel assembly is formed in the lens, the lamp panel assembly used for emitting a light source is arranged in the cavity, and air flows among the outer barrel, a through hole, a flow guide channel and an inner barrel. A smoke window effect can be formed, so that the air flow speed is increased, heat exchange between heat in the down lamp and air is accelerated, the problem that in a common mode, a discrete heat section in the lamp panel assembly is too far is solved, the back of the lamp panel assembly can be cooled by the air flow, and the power density and the material utilization rate are improved. 本实用新型公开了一种筒灯结构，包括外筒，所述外筒底端设有一透镜且透镜内设有用于容纳安装灯板组件的空腔，所述空腔内设有用于发出光源的灯板组件，外筒、通孔、导流通道和内筒之间的空气流动，可形成一烟窗效应使得气流流速变快，加快筒灯内部热量与空气之间的热交换，避免了一般方式下灯板组件内部离散热段过远的问题，使灯板组件背后都能受到气流的冷却，提高了功率密度和材料利用率。
