What should I do if the projector bulb darkens? Generally speaking, the distributor of the projector's optical lens assembly can't be turned on, and the light path components such as the liquid crystal panel are not suitable to be turned on, resulting in the dust accumulated in these two main components not being completely cleaned up. The dust adhered to the light path components such as the liquid crystal panel is the main reason for the brightness reduction.
Therefore, it is often impossible to fundamentally improve the brightness of the projector only by cleaning the general dust inside the projector or replacing the light bulb. In order to fundamentally improve the brightness of the projector, we can only overhaul the projector and replace the LCD panel assembly and optical lens assembly.
In order to solve the problems of low brightness, color distortion and LCD panel damage, we think that comprehensive measures should be taken to deal with them. To sum up, the solutions are as follows: replace the light bulb in time; Maintenance of projector; Replace projector parts; Update the projector; Strengthen use management, put an end to irregular operation and control non-teaching use.
Different applications have different requirements for projectors. How to dim the projector light bulb When using in training, lectures and seminars, for better communication, the indoor lighting is usually bright, so the brightness of the projector is more needed. The light bulb of the projector is dimmed. When it is used in the classroom, it mainly projects tables, graphics or videos, and the requirements for the brightness of the projector will be relatively low. Therefore, it is wise to make clear the actual use of the projector first, and then determine the brightness, so that you can appropriately increase or decrease some brightness when purchasing.
