Believe to be familiar with the friend of projector, brains often has such consensus, that is as projector " enlist in army " the progressively growth of time, its output brightness to also be met progressively and bleak, until till it is not clear to project the appearance content that come out looks. A kind this kind of phenomenon also is projector actually " physiology " phenomenon, anybody cannot be prevented or it is changed, once had human wisdom,do not pass this one course participate in, so of projector " ablaze " deadline can get be extensioned as far as possible! Do not believe, ask everybody to view the operation tricks of the trade below the article, believe these content can let projector certainly " ablaze " after all!
The society rests, make motivation more sufficient
Common saying says " learn to rest first only, ability learns the job " , to projector such truth is likewise applicable, let projector in time get only " rest " , ability lets projector better output is behaved, ability lets output the effect all the time " ablaze " after all. So why does projector need " rest " , we this how appropriate arranges good projector " rest " time?
Original projector is in the working process of time of train in excess specified length, its are umbriferous bulb can send out in projector interior an a lot of quantity of heat, because these quantity of heat cannot send out quickly inside proper time go out, because of this meeting accumulation is in projector is in-house, once cannot send out the meeting after quantity of heat accumulates certain level brings about projector interior temperature quick elevatory; and in continuously below high temperature condition, many optics of projector yuan parts of an apparatus appears very easily a kind of special optics " break fully " phenomenon, if this kind of phenomenon often happens, become in optics with respect to the likelihood produce spot like lens surface, and amount of this kind of stain also is met increasing as the elapse of time, if once the major area of surface of camera lens of optical spot name a person for a particular job is enclothed,living, so project from umbriferous bulb the radial energy that come out can get of stain serious " hold back " , come in that way the energy of output of significant light source of projector can decrease apparently, showing the direct phenomenon that come is umbriferous brightness not less than dropping before, was thought to reduce the generation of optical stain as far as possible, we must let projector after working for long, in time " rest " , so that let accumulation send out from interior in the quantity of heat of projector interior,come out, the optical component that assures projector interior thereby does not produce optics " break fully " phenomenon.
