The use effect of the projector during the day is influenced by the brightness of the projector itself. The higher the brightness, the better the daytime use effect. If the projector wants to project a bright picture during the day, it needs the actual brightness of the projector to be above 2000ANSI lumens, and it still cannot directly use the equipment under the influence of outdoor sunlight.
In addition, if the brightness of the projector is too low, which is lower than 1000ANSI lumens, the projection picture will be obviously whitened during the day. At this time, the shade is pulled, and the picture can be bright and clear again.

The projection quality of the projector is not only related to the brightness of the projection bulb, but also related to the influence of the projection environment. The light intensity of the projector working environment will directly affect the projection effect. Therefore, before using the projector, we must first arrange the working environment of the projector and make the projection bulb work in dim light environment as much as possible.
Bright ambient light will make the brightness effect of the projection bulb worse, making it difficult for students to watch. In order to make the projector get better projection effect, we might as well install dark opaque curtains in the room to block the outdoor light, and use materials that are not suitable for reflection on the walls of the room. These details will enable the projector to produce a better projection effect with the same brightness of the projection bulbs.
