除了标准的 A 型灯泡外,还有一种更细长的灯泡,被称为 A 型灯座。这种灯泡的形状更窄更长,通常像子弹或火焰。它通常用于装饰目的,特别是在烛台式照明灯具中。
A 型球茎中的 "A "指的是水滴形或花球形,通常与以下形状有关 传统灯泡.随着时间的推移,"灯泡 "一词已被广泛用于描述任何形状的灯泡,但 A 型指定专指这种特殊形状的灯泡。大多数标准螺口灯头灯泡(如通用电气 60 瓦白炽灯泡)都属于 A 型灯泡。A 型灯泡的常见例子包括 A-19 和 A-21,分别对应 60 瓦和 75 瓦的灯泡。

常見問題
LED A19 灯泡形状像雪锥,是公认的传统灯泡形状。这种灯泡已被广泛采用,成为客厅和卧室等不同区域的家用照明标准。
除了灯颈更长、灯泡更大之外,A21 灯泡与 A19 灯泡的外观几乎完全相同。它们的尺寸非常相似,因此可以在相同的灯具中互换使用,或用于类似的照明目的。
与 A19 灯泡相比,A15 灯泡的尺寸较小。这两种灯泡都可以在标准家用中型灯头(E26 灯头)中使用。不过,必须确保周围区域通风良好,以避免任何潜在的火灾危险。
