1. What does ANSI lumens mean?
To put it simply: ANSI lumens, formulated by the American National Standards Institute (ANSI), that use ANSI lumens to represent the light output of the projector, has been generally accepted internationally.
Professional explanation:
ANSI lumens refers to the main technical indicators of the projector. "Light out" is usually expressed in terms of luminous flux. Luminous flux is the ability to describe the strength of the visual response generated by the radiation of the light source per unit time, and the unit is lumens.
The international standard unit for projectors to express luminous flux is ANSI lumens, which is a method for measuring the luminous flux of projectors developed by the American National Standards Institute. It has been generally accepted internationally.
2. What does brightness mean
Simply put: it is the light emitted by the projector optical machine.
Professional explanation:
Projector brightness is an indicator that defines the brightness of the projector's image, in fact it is determined by the projector's light output. However, at present, there is no unified standard for manufacturers in the world, so there are different names such as brightness, illuminance, light output, etc. in each manual, and there are many units, including lux, lumens, peak white lumens, ounces ( ANSI) lumens, etc. In fact, in optical theory, there are strict definitions and units for the physical quantity representing the brightness of an object, but in daily use, people often refer to it as brightness.
