什么是等效瓦特数

等效瓦数比较了不同类型照明的亮度。 灯泡.它是一种度量标准,表示白炽灯泡的瓦特数,它能产生与被比较灯泡相似的亮度。消费者可以通过这一指标轻松了解和比较灯泡的亮度。 亮度 使用熟悉的测量单位测量不同灯泡的亮度。

等效瓦特数的概念与 LED 和 CFL 灯泡等更新、更节能的照明技术尤为相关。这些灯泡能产生与传统白炽灯相同的亮度,但耗电量却大大降低。通过提供等效瓦特值,即使使用不同类型的灯泡,制造商也能让消费者更容易地选择与他们所需的亮度相匹配的灯泡。

虽然等效瓦数是一个有用的参考点,但它不一定能准确反映灯泡的实际亮度。比较灯泡亮度的最准确方法是看 "流明 "等级,它衡量的是 出光量 灯泡的亮度。因此,建议在选择符合所需亮度水平的灯泡时,同时考虑等效瓦数和流明等级。

常見問題

100W LED 比 60W LED 更亮吗

请回答:如果您需要更亮的灯泡,飞利浦 100W 替代 LED 灯泡(右侧)的亮度比 60W 白炽灯泡(左侧)有更明显的提高。

什么是相当于 60 W 灯泡的 LED?

例如,如果您通常购买 60 瓦白炽灯泡,其亮度约为 700-800 流明,那么您可以选择 42 瓦卤素灯泡、12 瓦节能灯甚至 10 瓦 LED 灯泡等更节能的替代品,以达到相同的亮度水平。
