What indicators should pay attention to when choosing a projector?
2022-12-19
The projectors on the market have different prices, good and bad, and the parameters inside are also dazzling. Not only the owners, but many designers are at a loss. Designers want to understand, but it is actually very simple. Just avoid the screen large, poor picture quality, and low brightness, then it is necessary to grasp these core indicators. 1. Light source The type and brightness of the light source Projector light sources generally include LED light sources, high-pressure pump bulbs, laser light sources, and xenon lamps. LED light source Its advantage is that it can be used for a long time, but its disadvantage is also obvious, that is, the brightness is very low, so it can only be used at night or in a dark environment. High pressure pump light source The brightness is very high, so it has a strong heating phenomenon, so it needs to be equipped with a strong heat dissipation device, resulting in greater wind noise. In addition, its service life is relatively short. Xenon light source High brightness, short life, expensive Laser light source At the same time, it satisfies the two advantages of long service life and high brightness, and is an ideal choice For Projector light sources. The brightness of the projector's light source is usually expressed in "ANSI lumens". The higher the value, the brighter the brightness. Generally, household projectors usually choose a projector with a brightness of at least 2000 ANSI lumens to ensure that no matter at night or in bright daytime, All can be high-definition high-brightness picture experience and effects. In addition, light source lumens ≠ ANSI lumens The light source lumen is the initial brightness without any attenuation, and the ANSI lumen is the final actual brightness value.
