[Home Theater Network HDAV.com.cn] Whether it is summer or winter, home theater projectors work in the audio and video space, it is more difficult to dissipate heat, but to projector work, it is necessary to care about its health, for the projector more Good heat dissipation, especially when the projector is working continuously, heat is the biggest problem.
Source of heat
Even in the winter, or in the audio-visual home with low air-conditioning temperature, the heat of the home theater projector is very large, which is based on the continuous operation of the projector in a small space for a long time, the bulb will emit a huge Heat. At the same time, the built-in projector power supply will also emit a lot of heat. If it is not released in time, the projector will generate a high temperature inside, which will not only reduce the working efficiency of the projector, but also shorten the service life.
At the same time, when the home theater projector is working for a long time, the hot air emitted is also very obvious for the indoor temperature increase. It is already hot enough in the weather, how to ensure that the projection can effectively dissipate heat, and also for the viewer. Is it disturbed by hot air?
Need to clean the hood for the projector
The opening or hollowing design on the projector casing can ensure the effective ventilation of the home theater projector. The internally installed ventilation cover can also filter various pollutants or dust. It is necessary to clean these parts in time, otherwise the dust will hinder the air inside and outside the projector. Circulation. Therefore, regularly cleaning the dust or other contaminants on the hood is also a measure to ensure the projector's smooth heat dissipation.
The projector is a high-precision optical and mechatronic product. The internal components are very sensitive to temperature. In addition to the complexity of the internal structure, the temperature requirements of the projector are relatively harsh. Therefore, the projector has the same heat dissipation problem as many computer components. . At present, the home theater projector is developing towards portable and ultra-portable projection. The weight of the projector is getting smaller and smaller, the heat dissipation requirement is higher, and the brightness of the projector is also improved as a whole, which means that the heat generated is also higher. . All of this puts higher demands on the heat dissipation technology of the projector.
There are also some projectors that are easy-to-remove dual-channel cooling systems that take the form of a bottom heat sink. This way, the projector adapts to the external high temperature of 40 degrees, and effectively reduces the overall noise of the machine, giving the user a quieter environment. The easy-to-remove dual-channel cooling system locks heat around the bulb after a sudden power failure, preventing high-temperature conduction to other major components and causing greater losses. The bulb itself also uses a unique heat-conducting material to avoid damage to the wick caused by the high heat after a sudden power failure, and the heat-dissipating window at the bottom can also remove a large amount of heat in time. The fan port has also been specially added with a sealing strip to minimize the loss of ventilation and heat dissipation.
Make full use of the space and let the projector use the lifting method
It is one of the effective ways to dissipate heat through the small fuselage area of ​​the projector. When placing the projector, be sure to locate it in a ventilated area. Do not place any debris on the body, especially near the vents, and do not block it. Choosing hoisting is the best way to install a family-viewing projector. It ensures the reasonable ventilation of the product, and does not affect the influence of the excluded hot air on the viewers. At the same time, the difficulty of home lifting is not high, and the budgetary cost is also accepted.

There are many features that separate LED lights from traditional models. They have a reputation for excellence achieved through years of innovation and quality design that has enabled them to outperform competing models with ease. LED linear lights are specifically designed for taller ceilings and larger areas. They focus light more directly to create powerful illumination at a long range. This makes them perfect for commercial and industrial applications such as warehouses and retail stores. While there are many options when it comes to installing light fixtures in your building, choosing LED technology will give you a better experience that you will never regret.
