How to judge that the life of projector bulb is coming to an end?
It is not particularly reliable to judge the life of light bulbs by the degree of flowers. First of all, there is a protective cover on the projector bulb to prevent the bulb from exploding and damaging the lens inside. Take out the projection bulb every 1000 hours.
Second, the glass column in the projection bulb can be judged.
The protruding glass column in the projection bulb indicates that the service time is too long and the service life is almost up to the condition of replacement. This projector changes the light bulb.
Third, the light bulb of the projector can judge
Dim the light bulb and see how long it takes. Dust again to see the effect, if the effect still does not improve the brightness, it is necessary to change the lamp.
Extended data:
1, dustproof and scratch-proof.
Dust prevention is very important in the use of projector, and dust particles are more easily adsorbed in the optical system. At the same time, we should also pay attention to avoid scratching the lens, because if we are not careful, we will leave fingerprints, water marks, oil stains and so on.
2. Avoid vibration or collision
Strong vibration may cause the displacement of the liquid crystals, which will affect the convergence of the three liquid crystals during projection. RGB colors will not overlap, and the lenses and mirrors in the optical system will be deformed or damaged, which will affect the image projection effect.
3. Don't unplug the power socket or turn it off for cooling.
After the projector is turned off, it is best to let it cool for a period of time, because the sealed design of the projector is difficult to automatically dissipate heat. After unplugging the power supply, the photography fan will stop working immediately, so that a large amount of heat generated by the long-term operation of the projection bulb will accumulate inside the projector, which will seriously affect the electrical performance of the bulb and internal components, and even lead to the explosion of the bulb.
