The traditional projection light source is generally ultra-high pressure mercury bulbs, andlaser light sourceAs a new light source, LED light source has developed rapidly in recent years. Relatively speaking, the exposure rate of the laser light source is higher than that of the LED light source. Today, I 'd like to talk to you about the advantages of lasers that make them so attractive besides sounding higher than light bulbs.

In addition to listening to high school,laser light sourceWhat are the advantages?

The first thing to say is the color of the laser. The working principle of the traditional light bulb makes it emit a lot of messy light at the same time, which will naturally affect the color of the picture. Color bias was common in projectors of the past. Lasers can emit more pure light without being disturbed by clutter. Compared with traditional light bulbs, lasers are naturally superior in color.

In addition to listening to Gao Da, what are the advantages of laser light source?

Laser light source color advantage is obvious

The light from the laser is said to be pure. Some friends may say that the LED light source can also emit pure three-color light. Yes, the second advantage of laser is brightness. Subject to the bottleneck of technological development, it would be nice if the brightness of the bulb could reach tens of thousands of lumens, while the brightness of the laser could reach 70000 lumens. Whether it is a traditional light bulb, or LED light source, can only sigh.

It should also be noted that if the brightness of traditional bulbs is increased, this will have a great impact on the life of the bulb. For example, if the projector bulb can be used for 6500 hours in normal mode, the service life will be reduced to 5000 hours in high brightness mode. This is the third advantage of laser light sources: longevity. The service life is very long, up to tens of thousands of hours, which is very attractive to users.

Another thing to say is the stability of the laser. Long-term use of the projector friends should have a deep experience. Traditional light bulbs will have problems such as brightness attenuation and fading after long-term use. It's too bad to replace it. If you insist on using it, it will affect the viewing experience. It's simply chicken ribs. The performance of the laser light source is stable, and the above problems will not occur for long-term use, and users can watch movies at ease.

Advantages of laser light source projector: stable performance, cold light source, can be turned on and off instantaneously, without preheating and heat dissipation, and can reach brightness when turned on; long service life, slow brightness attenuation during long-term use, and service life can reach more than 20000 hours. Disadvantages: lack of flexibility; less classification; the price is relatively more expensive than ordinary projectors.

From the above we can see that in the PK of laser VS bulb,laser light sourceAlmost overwhelmingly. With the advancement of technology, the cost of laser light sources will definitely become lower and lower. It is believed that the laser light source must be the future trend of projection products.
