坎德拉（candela）是发光强度的单位，国际单位制（SI）的7个基本单位之一。 简称“坎”，亦称烛光，符号cd。 是一光源在给定方向上的发光强度，该光源发出频率为540×10^12赫兹的单色辐射，且在此方向上的辐射强度为1/683瓦特/球面度。

While lumens measure the total brightness of a flashlight, candelas focus on the beam intensity and throw. In simpler terms, lumens are the ‘amount’ of light, whereas candelas emphasize …

Candelas are a unit of measurement that quantifies the intensity of light emitted from a source in a specific direction. In the context of a boat, understanding candelas is essential for evaluating the performance of various lighting fixtures, particularly those used for navigation, safety, and aesthetic purposes.

Lumens and candela are both units of measurement that can be used to describe how much light is being delivered, but they differ. Lumens measure the total amount of light output by a source, while candela is more specific in measuring how much of …

2014年10月13日 · Candela is the base measurement for describing luminous intensity. It describes how bright the light source is, which shows how far away from an object you can be while still being able to see it. Even the brightest of light sources eventually become too dim to see once you are a certain distance from the light.

2024年10月14日 · Candela (cd) is a measure of the intensity of a light source, specifically the amount of light emitted in a particular direction. Unlike lumens, which represent the total light output, candela focuses on the directional distribution of light.

2020年11月28日 · En iluminación se refiere a la unidad física de intensidad luminosa y describe el flujo luminoso emitido por un iluminante en una cierta dirección. Una candela es equivalente …

Las candelas miden la intensidad luminosa, los lúmenes cuantifican la emisión total de luz y los luxes indican la iluminación sobre una superficie. Comprender estas diferencias es …
