Nowadays, more and more home appliance manufacturers are beginning to move closer to the laser television product line. With the deepening of a series of brands, laser projection has gradually gained the attention of the consumer groups. For families who love movies and have ample family space, building a home theater is no longer a dream. Looking at the projector market, we can find that the light source is mainly divided into three categories, namely, light bulb light source, LED light source, and laser light source. What is the difference between these three types of light sources? Why do most people in the industry regard laser projection as the projector's future product? Let us solve it together. Looking at the market, we can find that different forms of light sources have achieved development in different fields. For example, traditional lamp light sources currently have a wide application area, and the market has a large proportion, occupying not a small share in the commercial and domestic fields. Laser light sources can Ultra-high brightness is used in professional fields such as digital cinema and engineering fields, while LED light sources are mainly used in entertainment, miniature portable projection equipment and other fields. Traditional bulb light source: The essence of traditional light sources is mainly ultra-high pressure mercury lamps and xenon lamps. It is the projection light source with the longest development time and mature technology. The scope of application covers a wide range of fields including home, business, engineering and education. It is a light source with a higher proportion in the projector market. The projectors that are basically seen in classrooms and meeting rooms are products of traditional light sources. The brightness of traditional light sources is as high as 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 that the price is low and the cost is greatly reduced. At present, traditional light sources are mainly used in basic products and high-end products. High-end products are mainly because of their good color performance, so there are bulb light sources in high-end home theater products. However, conventional light sources have a fatal flaw: short life. The life of the bulb light source under normal use conditions is generally concentrated around 4000-6000 hours, which is quite different from other light sources. The attenuation of traditional lamp light sources during use will make the images darker (yes, the brightness decays, the contrast of the color saturation decreases, etc.). For a demanding location such as a movie theater, the bulbs have to be replaced for this purpose. The cost of post-maintenance is high. LED light source: The development time of LED light source projector is also very long, its special body is smaller, portable, and easy to use. At present, the performance of LED light source projectors has reached the level of high-definition. The mainstream LED light source projectors are mainly based on a few hundred lumens of high-definition projectors, and have been recognized by many users, bringing great convenience to small businesses and personal entertainment. Due to the simpler structure of the LED light source, the size and power consumption of the projector are effectively reduced, and the LED light source projector is more portable. At the same time, the lifespan of LED light sources is long, generally around tens of thousands of hours, and the performance in the color gamut is also very prominent. However, brightness is the biggest drawback of LED light source projectors, and it is always difficult to break through. Because the technical bottleneck of LED light source is still relatively obvious, the emission frequency of the green LED is relatively low, the heat dissipation problem is more prominent, and the cost is also relatively expensive, so the highlighted LED micro projector has been difficult to appear. Laser light source: Laser light source can be said to be the most concerned projection light source in recent years. In the past two years, laser light sources have gradually moved from the professional field to the daily life field. As far as the current situation is concerned, both the traditional business and education markets and the engineering and home markets that are in full swing have huge potential for laser light sources. Just as yesterday, Mi Jia also set foot in the field of laser television and launched a 150-inch laser television product. The reason why the laser light source is selected may be that the laser light source has characteristics such as large wavelength selectivity and high spectral brightness, which can synthesize more than 90% of the color gamut coverage of natural colors seen by the human eye, and achieve perfect color reproduction. At the same time, the laser light source has a high brightness and a long service life, which greatly reduces the post-maintenance maintenance costs. At the same time, the laser projector can be started almost instantaneously and the working brightness can be reached instantaneously. Therefore, the laser light source projectors all look like a quick switch. The traditional light bulb requires a certain period of time to reach a stable operating temperature when it is turned on, and it takes a certain period of time for the heat to be dissipated when the power is turned off, and the switching mechanism is time-consuming. However, due to technical and cost issues, RGB tri-color lasers are too expensive. Currently, the market price of laser light source products is generally too high, and the degree of popularity is not ideal. It is impossible to replace traditional light sources and LED light sources in the short term. However, the laser light source must be an inevitable trend for the development of future projection light sources. With the continuous innovation of technology, laser light sources will soon become popular in the projection industry, and the price will no longer be a problem that hinders the development of the industry. Written at the end: From a theoretical point of view, a projector using a laser light source can realize a color space that is much larger than that of a conventional light source, and its color performance is higher than that of a conventional light source projector. At the same time, the traditional projector will produce brightness attenuation, color saturation, reduced contrast and other phenomena during use, which will make the output image quality much less than the new projector. The use of laser light source projector due to the low attenuation characteristics of the light source so that the output quality of the long-term maintain high brightness, color saturation and contrast, the screen color is always bright as new. In the long run, since laser projection technology is used by many manufacturers in the industry, its production costs and price barriers will fall within a certain period of time to acceptable levels for ordinary users. Taking into account the product maintenance costs and the performance of the product, the laser projector is the best tool for home theater.
