Have to say the secret of the projector shutting down quickly
In today's increasingly pursuit of efficiency, every second seems precious. As the scope of application of the projector becomes wider and wider, the 2 to 3 minutes waiting for the projector to turn on and off is no longer trivial, but it seems so long, which not only affects the work efficiency, but also affects the user's image and mood. In response to the pursuit of efficiency by business users, more and more projectors now support the technology of rapid shutdown, which brings higher efficiency of business projectors to business users, realizing immediate use and immediate exit. NEC, which has the second largest market share in the global projector market, has made great achievements in heat dissipation and rapid shutdown. Let's take a look at the secrets of the rapid shutdown of the projector. Details to ensure projection safety Different quick shutdown Another solution is to set a capacitor inside the projector, which is equivalent to a battery or UPS. It is charged when the projector is running. After the projector is cut off, it still maintains the power supply to the cooling fan, allowing the fan to continue to rotate for a period of time. Time to cool the projector lamp. Although you can unplug the power immediately after turning off the projector, pay attention to ventilation. Cooperating with the function of keeping the fan running after power off, most projectors can control the shutdown time within 30 seconds, and the power can be unplugged after shutdown, so as to realize the function of quick shutdown. For example, NEC ’s VT49 + / 490 + / 590 + / 595 + / 695 + / 695C / VT700 + series projectors can be unplugged immediately after shutting down, using the dual-channel cooling technology to quickly dissipate the lamp, and the cooling fan can be used within 30 seconds. The operation can be stopped in the office, and the business user can take the projector immediately after the presentation is completed. The fast shutdown solution adopted by the NEC projector NP series is more advanced and perfect. It is to provide an improved heat dissipation method for the lamp, control the temperature of the lamp at work, and the fan can continue to rotate after the shutdown to cool the lamp, but this The method can control the time that the fan keeps rotating at about 10 seconds, so as to achieve rapid shutdown. For example, NEC ’s NP40 + / NP50 + series projectors use an improved heat dissipation method with a built-in air compressor to provide high-pressure, high-speed airflow heat dissipation around the lamp through a pipe to control the temperature of the lamp to a low level, in conjunction with fan cooling Allow the projector to be unplugged immediately after shutdown, and the fan will stop after 10 seconds of operation after shutdown, which is convenient for users to quickly take the projector away. to sum up Double Bowl With Drainer,Middel East Granite Sink,Two Bowl With Drainer Granite Sinks,Drainer Granite Sinks HESHAN ULA KITCHEN UTENSILS CO.,LTD , https://www.ulakitchenware.com
As we all know, when the projector is running, the lamp will generate huge heat. A cooling fan inside the fuselage is needed to dissipate the lamp. After shutdown, the cooling fan will continue to run for a period of time to reduce the temperature of the lamp to ensure the cooling of the lamp. In order to ensure the service life of the bulb, the power supply cannot be cut off immediately at this time, otherwise the fan stops rotating and the heat of the bulb cannot be dissipated, which will seriously affect the service life of the bulb and even damage it. Although it is a detail, if it is mishandled, it will cause fatal damage to the projector. But sometimes the conditions do not allow us to wait for 2 to 3 minutes, and it is very inconvenient to turn off the machine like this. For this reason, the NEC projector has designed a quick shutdown function to minimize the cooling time of the projector lamp to provide users with work efficiency.
Although they all claim to be fast shutdowns, various projector manufacturers have different ways to achieve fast shutdown, and the speed of shutdown is naturally different. The simplest solution is to strengthen the heat dissipation capacity of the projector, so that the projector can be quickly cooled after being shut down, and the function of rapid shutdown can be realized. However, this method still cannot unplug the power immediately after shutting down. You still need to wait for the cooling fan to stop before unplugging the power to achieve a complete shutdown. Depending on the heat dissipation capacity, it can be shut down within 20 to 40 seconds.
The fast shutdown function can greatly shorten the waiting time for the projector to shut down. At present, all NEC series projectors support the fast shutdown function, which is especially suitable for business users who are pursuing high efficiency. However, after understanding the various quick shutdown modes of the projector After the difference, consumers can choose different products according to their needs for shutdown time. If users with more stringent requirements for fast shutdown time, they may choose to adopt the NP series projector products with more advanced heat dissipation methods to make shutdown more quickly, and Ensure the life of the projector.
