    • An air-cooled lamp bulb includes a central tube, a circuit board disposed inside the central tube, a circular light wall surrounding the central tube, a transparent dome surrounding a top end of the circular light wall and having a top central opening, and a first air passage formed between the central tube and the circular light wall. The circular light wall is formed by a plurality of light units arranged side by side. Each of the light units has a light source mounted adjacent a top end of the central tube. The transparent dome is arranged for modifying light emitted by the light sources. The first air passage allows air flow through the air-cooled lamp bulb.
    • 风冷灯泡包括中央管,设置在中心管内部的电路板,围绕中心管的圆形光壁,围绕圆形光壁的顶端的透明圆顶,具有顶部中心开口,以及 第一空气通道形成在中心管和圆形光壁之间。 圆形光壁由并排布置的多个光单元形成。 每个光单元具有邻近中心管的顶端安装的光源。 透明圆顶布置用于修改由光源发出的光。 第一个空气通道允许空气流过风冷灯泡。
