Previously, laser projectors were considered exclusively professional. They were used at weddings and concerts, at large parties and festivals. There are many home models on sale today. When buying such equipment, it is worth considering some characteristics, otherwise the use will not bring pleasure.

Main characteristics

Home laser projector consists of a case, stand, power supply … Still maybe mount for installation on the ground . New Year's street projectors are frost-resistant. They do not deteriorate at temperatures down to -30 ° C.

The projector is installed in the desired location and connected to the mains. To activate, press a specific button on the case.

If you intend to use it in the cold, then you should wait about 15 minutes. During this time, the projector will warm up and be able to fully function.

Advantages and disadvantages

Laser projectors can be used for home theaters or offices . It all depends on the specifics of the model.

All products share some advantages

1. These devices provide a better image quality than their tube counterparts.
2. Versatility when choosing a screen. You can project a picture onto any surface.
3. Laser projectors use a small amount of power. The savings are significant when compared with tube models.
4. Small amounts of heat are generated. Laser devices do not need serious cooling systems. This has a particularly positive effect on the weight of the case.
5. They make very little noise during operation.

The advantages are quite attractive, but some disadvantages can significantly reduce the interest in the models.

There are also disadvantages to laser projectors

1. The overall picture may look unnatural. This is due to the excessive saturation of individual colors.
2. There is no smooth transition between the shade palette. Soft tones are poorly reproduced by lasers.
3. High price. True, it all depends on the quality of a particular device. So, average models can cost 40-50 thousand rubles, but high quality - about 100 thousand rubles.

Review of the best models

Laser projectors are pretty fun to use. Specific devices are designed for specific tasks.

Criterias of choice

When buying, you should give preference to branded stores in order to avoid fakes. Experts assure that projectors pay for themselves in the course of use due to the long lifespan and energy savings . Low-quality models at a low price can not only ruin the evening, but also negatively affect your eyesight. Interestingly, laser projectors can be used for movies and for decoration. The New Year motive or other thematic image at the holiday looks especially interesting.

Power

A home laser projector can be used every day or just for decorating a space. In any case, power matters and is the most important selection criterion. There are two types of indicator.

1. Total power . It is calculated by adding up the values of all laser modules of a particular device. For example, if there are three standard colors of 1 W under the case, then the total power is 3 W. The characteristic directly affects the brightness of the image.
2. White balance power features … Especially important when buying a device for lighting effects, decorations for the New Year and other holidays. The characteristic affects the balance between colors. If the power in this mode is 1.75 W, then the red should have 1 W, blue - 500 mW, and green - 250 mW.

Scan angle and speed

This indicator comes second in importance. When comparing several models, it is worth being guided by simple calculations . For example, the specified speed is 30 kpps, which is not bad enough. This is the only way it will be at an angle of no more than 8 °, which is not used in practice. Usually the projector works at 40-60 °, which means that the scanning speed will actually be 12-15 kpps, which is not enough.

Experts believe that 40 kpps is sufficient for private use. With a working scanning angle, the real figure will be 20-25 kpps. True, there is still such a nuance as limitation. The scanning angle must be more than 30 °, otherwise the device will have to be significantly moved away from the screen to obtain a clear image.

Beam thickening rate

This characteristic is especially interesting and unusual. The beam thickness is uneven throughout its entire length. It is thinnest at the exit of their projector. The beam expands as it travels towards the broadcasting canvas. If it reaches the wall too scattered, the image is blurry, the color rendition is distorted.

For a street show or just for comfort, pay attention to when the laser begins to scatter the beam … The later the process starts, the easier it is to achieve a high-quality picture at a great distance. Otherwise, outdoor lighting effects will be unavailable, and you will have to tinker with home use.

It is worth noting that manufacturers usually indicate the recommended distance from the projector to the wall or screen.

Influence of stray light

The picture quality from a projector depends on many factors. Thus, stray illumination is considered to be extraneous lighting that is on the screen during the operation of the device. And it can ruin your nerves. Types of stray illumination:

• Sun;
• Street lights;
• any room lighting, garlands;
• light from lamps that comes from neighboring rooms, and sometimes from houses.

High power models can be placed on a window and used in daylight without compromising picture quality . Projectors are more intense, so the effects of ambient light are less noticeable. There is a problem, such models are especially expensive. If the budget is not enough, then you should create special conditions for the operation of the device. Extraneous light must be eliminated or minimized.

Working Modes

Laser projectors have their own characteristics. So the devices function in only two modes.

1. Extinguishing . The laser beam turns off, the mirrors change position when broadcasting animation or text. The process itself is quite fast and imperceptible to the eye, it occurs at least 100 times per second. This is how multicolored appliances work. Activation occurs automatically.
2. Modulation . Found on models with DPSS lasers. The task of the mode is to improve the quality of complex broadcast elements. Modulation allows you to increase clarity and make the color reproduction as high quality as possible. If the value reaches 30 kHz, then the operating mode is considered good.

Security measures

Laser models differ from lamp ones, in inept hands they can be harmful to health. It is worth remembering the basic rules of operation.

1. Do not aim lasers at your face.
2. It is forbidden to stand between the projector and the screen, or a wall.
3. Manufacturers strongly recommend that you do not open the device case yourself.
4. Protect the power supply from moisture.
5. Do not leave small children unattended with the projector.

The rules will protect yourself and everyone around you from damage to your eyes. It should be noted that the projector can cause significant damage . Also, for the safety of the device, falls and aggressive mechanical impacts should be avoided. Moisture can damage the device without a chance for repair.

In case of malfunctions, you can not make self-repair, you should contact the service center.
