How many hours can the projector watch at most a day? Who depends on the life of the projector?

Nowadays, many people like to use home projector instead of TV. Many people know that the visual effect projected by projector is better than that of TV, but they don't know much about its service life. Who depends on the life of the projector?

The projector is a digital product, and its principle is that the light emitted by the bulb refracts and reflects several times through the optical path, and then reaches the imaging module to enlarge the image. The projector with bulb light source generates a lot of heat and needs high heat dissipation. If the heat inside the projector can be removed in time, the life of the light bulb can be significantly prolonged, thus prolonging the life of the projector. Generally, the life of a light bulb is 2000 hours.

Of course, the light sources and service life of different projectors

First look at the classification of projectors. According to different light sources, projectors can be divided into traditional bulb light sources (mercury lamps), LED light sources and laser light sources. Among them, the traditional bulb light source is often used in the well-known bulb machine. BenQ, Epson and other traditional projection enterprises have many products with high brightness, which can generally reach more than 3000ANSI, and their service life is generally around 5000 h. If you watch it for 8 hours every day, the experience will begin to decline within 2 years.

LED light source is commonly used in intelligent projection at present. Paten, Jimmy and other smart projection companies commonly used, long service life, up to 20000 hours. If you use it for 8 hours every day, the experience will begin to decline after 6 years, but the brightness of LED light source is low, generally around 2000ANSI.

Finally, the laser light source is the most suitable light source for projectors at present, with a long service life, which can reach more than 30,000 hours. According to the situation of using it for 8 hours every day, it can maintain a good use experience within 10 years. Of course, the loss of other components should be considered when using, and the brightness of laser light source can reach above 3000ANSI. We can see that the projector with laser light source has a long service life, and its high brightness and long service life meet the two most important parameters of the projector. In addition to long service life, laser projector is much higher in brightness and color expression than LED light source, and its energy consumption is much lower than that of LED and traditional light bulb. It is a very good choice of projector light source. Now many international manufacturers such as Samsung and Sony are stepping up research and development of laser technology. So which laser projector should I choose? At present, the response of Betan X3 laser projector in the market is not bad.

Having said that, how long can the projector watch for a day at most?

In general, many users will drive home projector for more than 10 hours continuously. But! It is impossible for any electronic product to run continuously for a long time. If the projection bulb works for a long time, the imaging system inside the projector may emit a lot of heat, resulting in a rapid increase in the temperature inside the projector. Because the inner wall of the projector bulb will crystallize at high temperature, white spots will appear, so crystallization will block a lot of light, which will lead to an abnormal increase in the temperature of this local area, which will further expand the crystallization area, leading to a rapid decline in brightness and an explosion of the bulb. So be sure to keep the projector working for no more than four hours at a time.

Like the portable projector at home, there is only one built-in fan, which leads to poor heat dissipation performance of the machine. In general, you can reach out and feel the temperature of the socket of the home projector. If you feel a little hot, you'd better turn it off. Usually turn off the projector for 3 to 4 hours to have a rest.
