How much is 55000 lumens equal to ANSI?

Extended data

How much does it cost to convert 3000 lumens of projector into ANSI?

Generally speaking, lumens are ANSI lumens, and projector 3000 lumens are ANSI3000 lumens.

ANSI is the abbreviation of American National Standards Institute.

ANSI Lumen is a standard for measuring projector luminous flux formulated by American National Standardization Association. It measures the illuminance of each point at nine intersections of the "sky" shape on the screen, multiplies it by the area, and then calculates the average of the nine points, that is, the ANSI lumens of the projector.

Extended data: Lumens (symbol lm) is the international unit of luminous flux.

It is defined according to Candeira spherical angle (cd times sr).

The first stream emits a considerable amount of light in the unit of 1 spherical angle, and the same amount of energy is emitted from the light source in all directions, with the intensity of 1cd.

ANSI lumen (LM) simply refers to the brightness of a candle at a distance of one meter (1m = 1m).

At the solidification temperature of platinum, the luminous flux radiated from the area of 5.305* 10 cm is1mm.

In order to illustrate the relationship between light intensity and luminous flux, the luminous flux of a point light source with light intensity of 1 Candeira in unit solid angle (1 sphericity) is 1 lumen.

When the luminous flux of an object uniformly irradiated by light in the area of 1 m2 is 1 brightness, its illuminance is 1 lux.

Sometimes, in order to make full use of the light source, a reflector is usually attached to the light source, so that more luminous flux can be obtained in some directions to increase the illumination of the irradiated surface.

Such as car headlights, flashlight, photographic lamp, etc.
