We all know, the heat is Projector Lamp Deadly killer, and this is why many manufacturers have repeatedly stressed the heat dissipation reasons. Authorities in the projection plane, the best allowed to cool for some time. Because the projector design is difficult to automatically heat sealed, and disconnect the power, the projector fan will immediately stop working, after working long hours this way light bulb projected a lot of heat generated will accumulate in the projector itself, seriously affect the light bulb and internal components Electric Performance, the worst case, can lead to the phenomenon of light bulb exploded. 2, fast shutdown due to a new cooling system
To avoid this phenomenon, we should use, first turn off the projector switch, so that projector fan to continue cooling, until the heat distribution inside the projector after the projector fan will automatically stop the rotation, and then cut off the power at this time. Course has fast shutdown function Business Projector In this respect slightly better, but if it is not necessary or not to immediately shut down. 3, prolonged use of projector Best not to use the projector a long time, because of limited air-cooled, after all, that is why there is a lifetime of bulb. That fan is not sufficient to remove all the heat, and prolonged heat accumulation will decline to bulb or even burst. Therefore recommended that users generally do not use the projector when more than four hours straight. 4, switching frequency in high Many
Electronic The switching components are present, "breakdown" dangerous, which is why we use Computer Time to avoid frequent switching machine. The same bulb is "Johnson" "expensive," especially to support rapid start of the projector, and instantly realized with a high current short warm-up time, will increase the risk coefficient for a file, so when we do not use the projector frequent switching machines, to avoid frequent light bulb and the circuit by the impact of current or voltage. 5, the boot state of shock projector
Although the use of process, in addition to the fixed installation, we inevitably have to move the adjustment, but gently is a necessary good habits, because the full-powered projector working conditions, the bulbs will a lot of heat generated, the heat generated within the filament bulb temperature will melt in a close state, which is why the expensive metal filament using a variety of reasons for high melting point. Well, this semi-molten state, if the projector by the shock, the impact on the light bulb is no doubt bear the brunt, but if the temperature of the filament drop, so do not just turn off the light bulb, light bulb burst potential is there, so to avoid vibration is very important. 6, with Shot Block the projection light cover We use the projector in the process may rest, but do not want to turn off the projector, and if in this period of time so that the projector has been lit, then, will feel very uncomfortable, can often be stopped with the lens cap But the point to note is not a long time to use the lens cap, so that the heat of light projection was barred from office the cameras, long time, will inevitably result in high-temperature camera and light machine damage.
