low power laser light sourceIt is an electric light source that uses excited particles to emit light under the action of excited radiation, and is a coherent light source. Low-power laser sources can be divided into four categories according to their working substances (also known as active substances): gas laser sources (including atoms, ions, molecules and excimer), solid laser sources (crystals and neodymium glass), liquid laser sources (including organic dyes, inorganic liquids and chelates) and semiconductor laser sources. Now on the market there are a lot of laser light source projector, many businesses also to the user to push the laser projector, so someone asked this laser light source projector and traditional light source projector what is the difference.

1. Which Is Bright? Laser Projector Uses Bluelow power laser light sourceAs a light source, a conventional projector uses a high-pressure mercury lamp as a light source. As long as the brightness index is the same, the two light sources are the same brightness, and there is no argument that who is brighter than who.

Frankly speaking, in theory, a projector using a low-power laser light source can achieve a much larger color space than a traditional light source, and the color performance is higher than that of a traditional light source projector, but in fact the average user can't tell the difference. However, it is important that the traditional projector will produce phenomena such as brightness attenuation, saturation, and contrast reduction during use, which greatly reduces the quality of the output image compared to the new projector. However, due to the low attenuation characteristics of the low-power laser light source, the output quality of the projector maintains high brightness, saturation and contrast for a long time, and the color of the picture is always bright as new.

3. who has a longer service life? When it comes to service life, low-power laser light sources definitely win by absolute advantage. The light source life of ordinary projector bulbs is generally about 2000 to 3000 hours, and the laser structure of laser projectors is highly reliable. According to the existing experimental results, it is estimated that its life can reach 00000 hours, and it can be used for a long time without maintenance.

4. the laser light source still needs to be switched on and off for a long time? Because the laser projector can be started almost instantly and reach the working brightness instantly, the laser light source projector can be switched on and off quickly. The traditional light bulb needs to work for a period of time to reach a stable working temperature when it is turned on, and it also needs a period of time to dissipate heat when it is turned off, so it takes time to turn on and off.

How do 5. choose? In fact, both have their own merits, because the current uselow power laser light sourceThe home projectors are high-end products of various brands or flagship models, so the prices are relatively expensive and suitable for local tyrants with sufficient budgets. For ordinary users, the price is close to the traditional light source projector is actually a better choice.
