As a fast-acting multimedia demonstration device, commercial projectors have become an indispensable part of today's business activities. Commercial projectors are widely used in company conference rooms, corporate training, and business presentations. According to a market survey of small and medium-sized audio and video solution 500 gold medal partners conducted by Xiao Bian in 12 years, it is known that the use of commercial projectors in various corporate meetings and other occasions has become very common. However, in many commercial projector installations, there is often such a problem: how to buy a suitable projector in a commercial projector project. The conference room has always been an important application area for commercial projectors, depending on the use environment. Commercial projectors can be divided into mobile and fixed parts. Among them, mobile commercial projectors are constantly changing because of the occasions used, and portability is very important. However, in general, mobile commercial projectors are slightly more expensive and are not recommended for purchase; fixed commercial projectors do not require frequent movement, so portability is not required. High, it can be conveniently used in various conferences. Therefore, a fixed commercial projector occupies the main part of the conference room projector. Xiaobian 12 years of focusing on audio and video solutions 500 gold partners believe that the choice of commercial projectors should be placed above these points of attention: brightness, lumens, and distance between the projector and the curtain with the lens and other programs. 1, the brightness of commercial projectors In general, many customers believe that the higher the brightness of commercial projectors, the better, where Xiaobian said, as long as they can meet the needs of the conference room demonstration, it is best to use. The brightness of the projector is too high, but it will cause a waste of electrical energy. So what brightness is the most suitable commercial projector to use? Here, Zhe Haitian said, to purchase commercial projectors suitable for lumens, the brightness of commercial projectors must be determined, and the strength of the building structure and the dark intensity of light indoors must be taken into consideration. If the conference room is large and the brightness of the conference room is very high, then the commercial projector needs more screen size to play. If there is no shading device in the conference room, you should consider buying a projector with higher brightness. 2. Lumens of projectors Here are 12 years of small and medium-sized companies dedicated to audio and video solutions. Gold partners have given some indicators of commercial projector lumens for reference: The number of meeting rooms is less than 100 people, and a projector with 2500 lumens or so should be selected. The number of people in the conference room is 100-200 people, and 3000 projectors should be selected. The number of people in the conference room is more than 1,000, and 5000 lm projectors should be selected. Xiaobian 12 years of focus on audio and video solutions 500 gold partner reminder: try to place the curtain and other places in the dark room to get a better projection effect. 3. Distance and Lens of Commercial Projector The 12th year of Xiaobian focused on audio and video solutions. The top 500 gold partners believe that: the projectors used in commercial projectors have different lenses, and the projected image quality is also different. At the same time, the projected screen size is also different. It is related to the distance between the projector and the curtain. If you want to use ceiling installation, then the distance between the commercial projector and the curtain is more important. After the distance between the commercial projector and the screen is determined, it is also necessary to check whether the screen size is enough, and whether part of the screen is projected outside the screen. The projection lens of the commercial projector has good adjustability, and the size of the projected picture can be conveniently adjusted. The distance between the commercial projector and the curtain needs to be determined according to the building structure of the conference room and the number of people. The replacement of the damaged commercial projector lens needs to be based on the specification. The above parameters. At present, Xiao Bian's rich experience in audio and video solutions for 12 years has enabled Xiao Bian to master the structure, operation principle, and debugging technology of numerous devices. Xiao Bian provides various options for commercial projectors that are not only close to the needs of customers. The comparability is even higher than that of peers, and you are welcome to ask for more information about the projector.
