Avoid excessive temperature damage to the projector

Hot summer, many users for their love machine installed on the radiator parts, then, as a large producer of the projector should take what measures to allow the projector effective cooling?

Different sources of heat on the projector caused damage to the location and degree are not the same. The large amount of heat emitted by the projector imaging system will cause the internal temperature of the projector to rise rapidly. And the projector bulb inside the wall of quartz at high temperature will be the phenomenon of failure to produce white spots, due to the failure of a large number of blocked light, so that the local temperature abnormally elevated, resulting in a further expansion of the loss-permeable region, This causes the brightness to decay rapidly and is likely to cause the bulb to explode. In addition to the projector inside the chip itself to determine the physical properties of its operating temperature is not allowed too high, other optical components once the temperature exceeds its range will also cause damage to optical components. and the projector power supply part of the heat will cause the power part of the temperature is too high, this will lead to the projector internal power of electrolytic capacitors dry, resulting in projector power power switch tube burned.

In the face of all these dangers, if we do not take measures to quickly eliminate the heat in the projector, it may damage the internal electrical components of the projector. At present, many of the projectors sold in the market are by the way of installing the fan group inside the projector, under the effect of the cooling fan, its interior will be in a thermal equilibrium state; Of course, this balance is related to the temperature of the projector using the environment, if the projector uses the ambient temperature exceeds a certain amount of time, The temperature of important parts within the projector will also exceed its rated standard.

Therefore, in the case where the ambient temperature has reached critical temperatures, in order to ensure that the projector in a variety of environments can be used normally, we recommend that users install temperature sensors inside the projector, and through it to real-time monitoring of the internal air temperature changes in the projector, and the temperature change signal feedback to the projector inside the special circuit to deal with. When the projector detects that the temperature changes have reached the area work critical point above, the projector inside the protection program will automatically run to start, to the projector power automatically cut off, lest the projector in the high temperature conditions to continue to work will be damaged.
