No one, even a very large television screen , can match the picture created by the projector. Especially if the projector is using ultra-modern laser technology in its work. Some interesting facts about laser projectors you can learn from this article.
Laser projector for home
Some of the laser projectors can be called direct heirs of traditional projectors on cathode ray tubes. As in lamp precursors, the image in laser projectors is formed by mixing the rays of the three primary colors. That's just the source of these rays in this case are not the electron-ray tubes, but rather powerful lasers. For 1 second the beam of the projector "runs around" the screen about 50 times, as a result, the human brain perceives the image projected by him as a whole. Sharpen, sharpness and color saturation of the image is achieved through a complex system of mirrors. Thanks to this, using a laser projector, you can get a very clear and high-quality picture on any surface, even without using a special screen . But because of the cumbersome system, large power consumption and considerable price, laser projectors are now rather expensive professional tools than home appliances. For example, released in 2015 by Epson, a laser projector for the home theater EH-LS10000 will cost fans of super-high-quality images in an amount equivalent to $ 10,000. The cost of office models of laser projectors ranges from 1000 to 1500 USD. In return, manufacturers guarantee high quality of the resulting picture, ease of management and a service life of at least 20,000 hours.
Holographic laser projector
Holographic projectors are an absolutely separate niche of laser technology. Their purpose is to create graphic effects during various shows, presentations, etc. Due to technical features, the projected image turns out to be flat, without drawing small details. But thanks to bright colors and the possibility of projecting onto any surface, the effect is much greater than the expected result. How can I use a holographic mini laser projector? To date, there are many absolutely opposite creative approaches to the use of laser projectors for the design of various events. But all of them in the end are reduced to a different combination of the following components:
- Beam Show. It consists in projecting light rays, various geometric figures and their combinations in space. The greatest effect of such shows is achieved through their accompaniment by smoke and fog generators.
- Screen laser show (Screen Show). It consists in projecting various kinds of flat images onto any relatively light surface (walls of buildings, slopes of mountains, smoke screens, etc.).
The color design of the laser show depends entirely on the color of the laser used in the projector. So, the most budgetary option is a holographic projector producing a beam of green color. This is because the green laser beam is the most visible to the human eye, and therefore requires less energy for generation. The most expensive is a full-color laser holographic projector, in which three lasers of primary colors (red, green, blue) are installed at the expense of mixing which can receive any other color.
