The importance of projector heat dissipation

[Gabe]

All high-power electronics have a problem to solve, and that is the heat dissipation of the device. The same is true of smart projectors, the heat dissipation is very important.

Let us learn the impact of overheating to the projector.

1. Impact on projection brightness and color

As most of household smart projectors now use LED light sources, projector overheating will cause a serious impact on brightness and color. That is because the red light source in the LED light source is particularly affected by temperature, too high or too low temperature will make it lose brightness, this time the LED green light source and blue light source in order to maintain color balance will reduce brightness, with the reduction of the brightness of the primary color light source, the brightness of the projector is naturally low. And if the green and blue light sources do not reduce the brightness the first time to maintain the color balance, then the color of the projected picture will be biased.

2. Impact on projection electronic components

The temperature resistance ability of the electronic components of the projector is also limited. If the heat dissipation is poor and the temperature is too high for a long time, the electronic components may be deformed, which not only has a great impact on the projection picture but also makes the projector stuck, frame drop and forced shutdown. That is because the core of the projector - processing chip, in the ultra-high temperature chip clock frequency will be greatly reduced, which also caused the projector lag and frame drop. Again serious will trigger chip self-protection function, forced shutdown.

When buying projection, we have to consider the effect of heat dissipation, a projector that has excellent heat dissipation has longer life. Of course, the daily projector ash cleaning should also be done, not only rely on the projection of its own heat dissipation.

You're right, projector cleaning is important but often be ignored.
