什么是平均流明
平均流明,也称为 设计流明是一个术语,用于描述灯泡在整个使用过程中产生的平均光输出。 額定壽命.它用来衡量照明设备在其使用寿命内发出的平均光量。平均流明的概念对于了解灯具的性能和效率至关重要。灯泡在使用过程中,其光输出会随着时间的推移而减少。通过了解灯泡的平均流明值,用户可以对其照明投资做出明智的决定。
荧光灯的平均流明值是按灯泡额定寿命的 40% 计算的。也就是说,荧光灯的平均光输出是根据其总额定寿命的 40% 的性能来确定的。此外,有些荧光灯,如 T5 灯这些灯的效率很高,即使在使用寿命结束时,仍能保持其初始光输出的很大一部分。这表明,随着时间的推移,这些灯具的光输出衰减极小,因此是具有成本效益的选择。

常見問題
1000 流明的亮度对房间来说是否足够?
要确定房间的适当流明数,应先计算房间的平方英尺,然后乘以建议的英尺烛光要求。例如,一个面积为 100 平方英尺的起居室通常需要 10-20 英尺烛光,大约需要 1,000-2,000 流明。同样,面积相同的餐厅,如果需要 30-40 英尺烛光,则大约需要 3000-4000 流明。
增加照明是否会提高亮度
瓦数和流明并无直接关系。虽然瓦数越高的灯泡通常发出的流明越多,但由于灯泡效率的不同,瓦数相同的 LED 灯泡之间的流明数量仍然会有差异。
室内照明的最佳流明是多少?
我们建议使用 2000 到 4000 流明的总输出。
