About light source lumens and ANSI lumens explanation
1. the standard unit of projector brightness is ANSI lumens
For brightness, this indicator defines the brightness of the image of the projector, in fact, it is determined by the light output of the projector.
However, there is no unified standard for this among the world’s manufacturers, so there are different names for brightness, illumination, light output, etc. in each manual; there are also many units, including lux, lumens, peak white lumens, ANSI lumens, etc.
The international standard unit of the luminous flux of a projector is ANSI lumens, which is the method of measuring the luminous flux of a projector developed by the American National Standards Institute. It has been more commonly accepted internationally.
2. the difference between light source lumens and ANSI lumens
For light source lumens and ANSI lumens, we can commonly understand as follows
Light source lumens: the brightness of the light machine inside the projector, in fact, the brightness of the projected light seen by the naked eye, will be much lower than the light source lumens.
ANSI lumens: This is the brightness of the light projected by the projector. If the business is labeled light source lumens, it is best to ask the customer service directly, the ANSI lumens of the product is how much, unified use ANSI lumens to compare the brightness of different products, so that more accurate.
3. according to their own use of the scene to choose the right light source
- Household projector lumen values between 150-2200 ANSI lumens.
- Education and public use projectors are generally around 2000ANSI lumens.
- Digital projectors used in theaters are generally above 4000ANSI lumens, the last of which is difficult for us to access in normal life.
Use scenario suggestions.
1. if the projector is used as a TV in the bedroom at night, 150-1000 ANSI lumens of LED light source brightness are sufficient.
2. if you want to get a projector in a bright living room, it is recommended to choose 2000 ANSI lumens or more lamp light source or laser light source projector.
3. in turn, that is, if you want to watch the projection in the living room during the day, only the traditional light bulb projector and laser projector can meet your needs. the LED light source projector needs to pull the curtains to have a better effect.
