How To Use Mini LED Projectors Covered From A To Z!

What is the difference between various mini projectors and prices, and what are the key characteristics when choosing the right projector with mini size? During your purchase of a mobile projector, you should first determine the requirements for the projector. But don’t you worry about a thing, as with the help of this buying guide for mini projectors you will find out all the important factors you need to pay attention to when purchasing a portable projector.

What is the purpose of the projector?

Mini projectors can be used at home for watching movies and TV shows, in the office for doing presentations in front of your coworkers, at exhibitions and showrooms, in stores and bars, in schools and kindergartens, and in cinemas. Yes, yes, even in theaters, projectors are used. True, very narrowly specialized. The market is now offering many different lightweight projectors which are very portable, so the customers opt more for these.

In which room is the projector used?

In the room itself, of course, all electronics must be dry and comfortable. But especially important is the presence or absence of curtains and windows, that is, what “parasitic” illumination will be and the projection distance. The brightness of the best projector under 1000 may or may not allow the display of an image in a bright classroom from the distance of the first desk or a closed exhibition hall from the other end of the room.

What is the expected area of ​​the projection?

Usually, not even the area is measured, but the projection diagonal, as in TVs. Say a diagonal of 1 meter (40 inches) corresponds to the image size of 90×50 cm. A diagonal of 2 meters corresponds to 165×95 cm. There are even projections several times larger. And what’s the one that you guys need?

Where is the image projected?

This is the one in the cornerstones of enjoyable viewing. It directly affects the brightness and clarity but it does not depend on them. As for the simplicity: a specialized screen has a surface with special parameters of light reflection, so that most of the brightness emitted by the lamp is reflected to you. Otherwise, the picture will be faded. Of course, the craftsmen do not just invent in return: a white wall, a banner of advertising banners, suspended ceilings, etc. Although they are sometimes expensive, these projector screens are particularly large. But you want a bright live picture, not pastel colors, right?

Types of lamps in projectors

Now there are projectors on sale with one of the three kinds of lamps:

HID lamps of the first generation of projectors. They are encountered less often, as they have a small brightness and an uneven spectrum with peaks of individual colors.

LED – bright lamps with a smooth spectrum, which allows you to show all the shades without distortion with low power consumption and other advantages.

Lasers are very bright, ideal for street shows at distances of tens of meters, but fabulously expensive for most buyers.

Therefore, now more and more people are buying LED pico projectors. These come with protective cases, which is a very important factor that needs to be paid attention to, says The BayNet.

Brightness of the projector. How to define and choose it?

This is a very important parameter and you cannot make a mistake. So, you need to understand what the manufacturers are talking about when advertising their particular type of small projector. The brightness is measured in lumens, but now there are special notes of ANSI lumens. What is the difference?

Lumens are the usual type of measurement brightness in white light. Before the white screen, put the pocket projector and fix the brightness. Usually this figure is from 800 to 8000 lumens.

ANSI lumen is a new type of measurement by color. It is a measure by color, not by light. A device is placed in front of the screen and the brightness of the green color is measured. Then the blue, and afterwards the red. Finally, the average value is calculated. However, after all, the white light is bright, but the color of the indicator is from 50 to 500 lumens with the same lamps! Pay attention to this when choosing new mini projectors. Sometimes a portable projector with ANSI lumens will be brighter than usual. Besides, carrying a small portable projector is much more convenient than a large one, according to The BayNet.

What is the brightness of the projector?

So, using the most popular classification of lumens, we can conditionally separate the mini projectors (their lamps actually) into the following groups:

  <1000 lumens – home use in a dark room;

  1000 – 2000 lumens – use in a shaded room;

  2000 – 3000 lumens – use in a room with open curtains;

  > 3000 lumens – ubiquitous use;

How to choose the projection distance?

For each projector, in the characteristics, the projection distance is indicated, but…this is a great and ever-limiting law of physics. The brightness is inversely proportional to the square of the distance. And that means: twice as far, four times as dim. Therefore, it would be nice to move the projector as close as possible to the screen, but the farther away, the bigger the picture. Therefore, choose the golden mean between the brightness and the size of the image. And remember that the brightness declared in the parameters is measured approximately along the average declared projection distance.

We hope you’ll make good use of this informative guide. Be sure to expand your knowledge about mini projectors, it’s the best way how to enjoy all the benefits of these gadgets. As The BayNet advises, you are solely responsible for your projector.
