流明-勒克斯计算器 — ANSI 流明与勒克斯转换 | TheaterOwl

Calculating Lumen & Lux is a fundamental and crucial step in home theater design. It is not just about measuring distance; it must be designed based on scientific evidence to maximize human visual perception limits and immersion. Incorrect settings can cause eye strain or fail to take advantage of resolution benefits. This tool complies with industry standards such as THX and SMPTE guides to provide the most precise data.

工作原理

This system utilizes complex trigonometry and optical formulas. Based on the input variables (screen size, resolution, viewing angle, etc.), it simultaneously calculates the minimum distance where pixels do not appear clustered and the maximum immersion distance that fills the entire field of view. All results are reflected in real-time, suggesting figures optimized for the user's environment.

应用场景

• When simulating the installation space before purchasing new Lumen & Lux equipment
• When wanting to optimize the performance of an existing home theater system and achieve professional-level tuning
• When needing to find a compromise for the best audiovisual experience within space constraints

如何使用流明转勒克斯计算器

在“流明 → 勒克斯”和“勒克斯 → 流明”模式之间切换。输入光通量值和面积即可换算。

勒克斯衡量每平方米的照度。流明衡量光源的总光通量。1 勒克斯 = 1 流明/平方米。

ANSI 流明在屏幕的 9 个点上测量。峰值流明仅在中心测量，比 ANSI 流明高 20–50%。始终以 ANSI 流明进行比较。
