上方为大,有带带状,椭圆形,清澈的玻璃灯泡;末端为有线的青铜底;下方内侧为长长的玻璃管,两侧为两个终端,上方为长长的玻璃棒和站台;两端终端垂直延伸;上下接有小线,形成圆形图案;上下接有细线并被拉伸,接上每条小线;侧面印有制造商名. 白炽灯泡或灯具通过白炽提供人工光. 电流被传递出薄丝状物,使其发热并发光. 玻璃灯泡有助于防止空气中的氧气到达加热的丝状物,否则会因氧化而迅速分解. 1809年由汉弗莱·达维爵士首次发明,灯泡由托马斯·爱迪生(Thomas Edison)推进,1879年他发明了碳丝. 1906年,通用电气公司引入了第一个钨丝管,这个丝管不会熄灭瓦斯并让灯泡内部变暗. 至1910年,钨丝的生产工艺得到改进并降低成本,成为出产量产量最实用的丝. 今天大多数白炽灯泡都使用钨丝.
