Nowadays, the penetration rate of projectors is getting higher and higher, and ordinary families have begun to use projectors, but many people are not clear enough about the brightness concept of projectors. It is easy to overlook when purchasing, which may cause The projector you bought cannot match the environment at home. In this issue, let’s take a look at how to judge the brightness of the projector. To fully understand the brightness, we must first look at the concept and features of the unit lumens of brightness.

What is "Projector Lumens"?

Lumens is a unit of luminous flux. It represents the amount of radiant light energy per unit time. It is generally used to measure the brightness of objects that do not emit light but rely on reflected light. A point light source with a luminous intensity of 1 candela (cd) is used in a unit of three-dimensional The luminous flux emitted within an angle (1 steradian) is "1 lumen", the English abbreviation (lm). ANSI lumens is a method for measuring the luminous flux of a projector developed by the American National Standards Institute. In projector products, brightness is the main technical indicator, and ANSI lumens is often used as the unit standard.

Under normal circumstances, the higher the output brightness of the projector, the brighter and clearer the image projected on the screen, but the perception of the brightness of the image by the human eye does not only depend on the brightness of the projector, but also depends on the ambient light. Intensity, image size, etc. have a great relationship. The stronger the ambient light, the dimmer the brightness of the image projected by the projector by the human eye, so the ambient light has a greater impact on the brightness projection of the projector, and it is not necessarily the brighter the better.

How to choose the right brightness of the projector?

Generally, the nominal brightness of the projector manufacturer on the machine is the peak brightness of the projector, which is the highest brightness that the projector can project, but in practical applications, the projector cannot be in the state of peak brightness for a long time, which will affect the normal brightness Color output and the life of the projector.

Therefore, when choosing a projector, you should not only refer to the nominal peak brightness, but also consider the optimized ANSI brightness, which is the brightness of the screen under the condition of the projector's color and brightness balance.

So what is the appropriate ANSI lumens for the brightness required in different environments?

Projectors with 300-500 ANSI lumens, which are generally used in micro-projector products, are more suitable for entry-level users; in 40-50 square meters of home or living room, the screen is generally 60-80 inches, choose 800-1200 ANSI lumens The projector is more suitable for 60-100 square meters; when the screen is 80-100 inches, the projector with 1500-2000 ANSI lumens should be selected; in the space of 120-200 square meters, the screen of 120-150 inches, Then you should choose a projector product with 2000-3000 ANSI lumens.

But it should be noted that if you want to get a better HDR display, you need to further increase the screen brightness. In addition, the output brightness actually does not really represent the brightness of the screen that the user sees. The same projector projects different sizes and different gains of the projection screen, the brightness of the screen presented will also be different, so when choosing a projection The needs of machine products need to pay attention to this point.
