Brightness is the light intensity that the projector product outputs to the screen, and also the brightness of the projected image. In general, the higher the brightness of the projector, the brighter the image of the same size projected on the screen, and the clearer the image. However, the brightness of the image that our eyes can perceive is not only determined by the brightness of the projector, but also greatly related to the intensity of the ambient light and the size of the image. The stronger the ambient light, the dimmer the brightness of the image perceived by our eyes. Therefore, users must choose the appropriate brightness according to the environmental conditions of their projector. It is not necessarily as bright as possible. In the case of the same other indicators, the higher the brightness is, the higher the price of the projector will be. At the same time, the brightness of the image perceived by our eyes will have a certain range. Beyond this range, the our eyes will feel uncomfortable, especially after watching the image with high brightness for a long time. Our eyes will feel tired and may get hurt to some extent.
It is necessary to remind the user that in addition to choosing the brightness index according to the space size, the user should also consider the lighting conditions of the use environment, screen type and other factors. Under the same brightness, different ambient light conditions and different screen types will produce different display effects. When users choose projector products, they should have a margin for brightness index. Because the brightness of the projector largely depends on the light bulb in the projector, the brightness output of the light bulb will decline with the use time, which will inevitably cause the brightness of the projector to be declined. After 2000 hours of use, the brightness of the projector product decays rapidly, so when users choose the projector product, they must have a comprehensive consideration of the brightness index.
Generally speaking, in the 40-50 square meters of home or reception hall, it is recommended to choose 800-1200 lumens for projector brightness, and 60-72 inches for screen; in the 60-100 square meters of small conference room or standard classroom, it is recommended to choose 1500-2000 lumens for projector brightness, 80-100 inches for screen; in the 120-200 square meters of medium conference room and ladder classroom, it is recommended to choose 2000-3000 lumens for the brightness of the projector, and 120-150 inches for the screen; in large conference rooms or auditoriums with an area of 300 square meters, professional engineering machines with an area of more than 3000 lumens should be selected most projectors, and the screens should be more than 200 inches.
