Traditional projection light sources are generally ultra-high voltage ** bulbs, and laser and LED light sources as emerging light sources have developed rapidly in recent years. Relatively speaking, laser light sources have higher exposure than LED light sources. Come and talk to everyone today. Apart from the fact that lasers are louder than light bulbs, there are other advantages that make it so attractive.
In addition to listening to the advantages of a tall laser source
The first thing to say is the color of the laser. The traditional working principle of light bulbs will cause it to emit a lot of messy light, which will naturally affect the color of the picture. Color cast is a very common phenomenon for projectors in the past. The laser can emit more pure light, without the interference of cluttered light. Compared with traditional light bulbs, lasers are naturally superior in terms of color.
Laser light source has obvious advantages in color
The front said that the light emitted by the laser is pure, and some friends may say that the LED light source can also emit pure trichromatic light. Yes, here I will say the second advantage of the laser, that is brightness. Constrained by the bottleneck of technological development, the brightness of a light bulb can be very great if it reaches tens of thousands of lumens, and the maximum brightness of a laser can reach 70,000 lumens. No matter whether it is a traditional light bulb or an LED light source, it can only sigh.
One thing that everyone should pay attention to is that if the conventional light bulb is turned up, then this has a very big impact on the life of the light bulb. For example, if a projector lamp can use 6500 hours in normal mode, the service life will be reduced sharply to 5000 hours in high brightness mode. Here is the third advantage of the laser: life. The long service life of laser light sources can reach tens of thousands of hours at a time, which is very attractive to users.
Structure of laser projector
The other thing to say is the stability of the laser. Friends who have used projection for a long time should have a profound experience. Traditional bulbs will suffer from problems such as brightness decay and fading after prolonged use. It's a pity if you change it, insisting on using it and influencing the viewing experience is simply tasteless. The laser light source is stable in performance and will not suffer from the above problems when used for a long time, so users can feel at ease.
Turn on the state of the laser TV projection effect real shot
From the above we can see that in the PK of the laser VS bulb, the laser light source has almost overwhelming advantages. With the advancement of technology, the cost of laser light sources will certainly be lower and lower. I think laser light sources must be the major trend of projection products in the future.
