Today, more and more home appliance manufacturers are moving closer to the front line of laser TV products. With the deepening of a series of brands, laser projection has gradually gained the attention of consumer groups. For families who love movies and have plenty of family space, building a home theater is no longer a dream. Throughout the projector market, we can find that its light sources are mainly divided into three categories, namely bulb light sources, LED light sources and laser pointer light sources, so what are the differences between these three types of light sources? Why do most people in the industry regard laser projection as the future product of the projector? Let’s analyze it together.
Throughout the market, we can find that different forms of light sources have achieved development in different fields. For example, traditional bulb light sources have a wide range of applications and a large market share. They occupy a large share in the commercial and household fields. To achieve ultra-high brightness, it is used in professional fields such as digital movies and engineering fields, and LED light sources are mainly used in entertainment, mini portable projection equipment and other fields.
Traditional bulb light source: The essence of the traditional light source is mainly ultra-high pressure mercury lamp and xenon lamp. It is the projection light source with the longest development time and mature technology. It has a wide range of applications, covering various fields such as home, business, engineering and education. It is a light source with a higher proportion in the projector market. Basically, the projectors seen in classrooms and conference rooms are products of traditional light sources.
The brightness of traditional light sources is high, up to tens of thousands of lumens. There is a lot of room for adjustment in terms of color, making it more adaptable. The most important point is the low price, which greatly reduces the cost. At present, traditional light sources are mainly used on basic products and high-end products. The high-end red laser pointer is mainly because of its good color performance, so there are also light bulb light source products in high-end home theaters.
However, the traditional light source has a fatal weakness: short life. The life of the light bulb light source under normal use is generally concentrated at about 4000-6000 hours, which is much different from other light sources. The attenuation of the traditional bulb light source during use will make the image darker and yellower (such as brightness attenuation, color saturation contrast reduction, etc.). For high-demand places such as movie theaters, the bulb has to be replaced for this, which also causes The cost of later maintenance is very high.
