In the near past,Many families still choose TVs and supporting audio equipment in audio-visual equipment, but now, projectors are gradually emerging, and with high-quality image quality and performance, it has won the favor of more and more users. In particular, laser projectors can not only provide a larger and clearer picture than traditional TVs, but also bring a more vivid and immersive viewing experience to the audience.
So, let's continue to understand the working principle of the laser projector, first of all, in terms of imaging, I don't know if you still remember the convex lens imaging principle you learned in middle school, when the object to the lens distance is greater than 1 times and less than 2 times the focal length, the imaging effect is inverted, magnified real image.
The same goes for thatLaser projectors use high-energy lasers to excite fluorescent substances to produce colorful light, and project the image onto the screen through a projection lens。In addition, compared with traditional projectors, laser projectors also have higher brightness, a wider color gamut, and a longer service life.
However, it is precisely because of the ultra-high light intensity and color accuracy of laser projectors that people are interested in:Doubts have arisen as to whether laser projectors can cause damage to the eyes
1. Are laser projectors harmful to the eyes?
Through the above understanding of how the projector works, we can find outLaser projectors also use the principle of diffuse reflectionUnlike televisions, computers, mobile phones and other electronic devices where the light directly enters the eye, the picture projected by the projector itself does not emit light, so it is less harmful to the human eye.
Not only that, but projectors also have unique advantages in reducing the burden on the eyesIt doesn't have high blue light and flicker, and many products now have smart brightness adjustmentThe projector will automatically adjust the brightness of the picture according to the ambient light, and it will maintain a comfortable light experience at any time, which is more eye-friendly.
2. Recommended laser projection in 2024
At present, there are three main types of mainstream projector light sources on the market: ALPD light source, three-color laser and super mixed light source, of which ALPD light source also contains a super panchromatic laser (mixed light). One of the lasers known for its comfort is the ALPD laser, which is usually used in most high-end cinemas and high-end car audio-visual systemsLet's take a look at the recommended products of ALPD laser technology.
Living roomALPDLaser projector recommendation——DangbeiX5
This projector has a true 1080p physical resolution and a brightness of up to 2450CVIA, and the picture quality is stunningAnd the hardware configuration is also cutting-edge in the industry, MediaTek's top processor MT9679 chip with 4GB running memory, 64GB of storage memory,This ensures smooth projector running speed and excellent performance even after long periods of use
in addition,Dangbei's ALPDLaser projector in addition to this model,XSeries also have dangbeiX5 Pro and dangbeiX5 UltraTwo advanced models,DangbeiX5As a basic model,Its strength has far exceeded that of many other brands,Its strength can be seen!
BedroomALPDLaser projector recommended——DangbeiD5X Pro
DangbeiD5X Pro is a thin and light laser projectorWith a brightness of up to 1250CVIA lumens, the picture quality is transparent and natural, and it can still maintain high definition even in a well-lit room. in3000Yuan projector,Its advantages in picture quality performance are still obvious。
At the same time, due to its low attenuation and low noise characteristics, there will be no disturbances even in quiet environments such as bedroomsIn addition, it supports autofocus and keystone correction, so it can quickly and automatically adjust the perfect picture even if you change the environment or angle frequently。If you are looking for a laser projector to use in the bedroom,Then DangbeiD5X Pro is definitely an option worth considering。
3. Summary
Needless to say,Compared to mobile phones, TVs and computers, laser projectors have little impact on the eyesAs long as we choose a regular brand and use it reasonably, laser projectors can not only ensure the safety of our eyes, but also bring a lot of fun to life.
