Projector classification:

1. Home theater type: the brightness is about 2000 lumens (with the development of projection, the number is increasing, and the contrast is high). The aspect ratio of the projected picture is mostly 16:9, and various video ports are complete, suitable for playing movies and HDTV, and suitable for home use.

2. Portable commercial projector: Generally speaking, a projector weighing less than 2kg is defined as a commercial portable projector, which is equivalent to a light notebook computer. The utility model has the advantages of small volume, light weight and strong maneuverability. It is a substitute for traditional slide projectors and large and medium-sized projectors.

3. Projectors for educational meetings: generally used in schools and enterprises, with mainstream resolution and brightness of about 2,000-3,000 lumens, moderate weight, good heat dissipation and dust-proof performance, suitable for installation and short-distance movement, rich functional interfaces, convenient maintenance and high cost performance, suitable for bulk purchase and promotion.

4. Mainstream engineering projector: Compared with mainstream ordinary projectors, engineering projectors have larger projection area, longer distance and higher brightness, generally support multi-bulb mode, and can better cope with large and changeable installation environment, which is very suitable for education, media and other fields, government and other fields.

5. professional cinema projector: this projector pays more attention to stability and low failure rate, and has strong heat dissipation performance, network function and ease of use. Of course, in order to adapt to various professional applications, the most important feature of shadow play instruments is high brightness, which can generally reach more than 5000 lumens, and the high brightness can exceed 10000 lumens.

Because of its large size and heavy weight, it is generally used for special purposes such as theaters, museums, great halls and public areas, and can also be used for traffic monitoring, public security command centers, fire fighting and air traffic control centers.
