All About LED Projectors

Projectors are classified as special equipment, they are used to project information from various sources onto the screen. Film and slides were the main media a few years ago. Today this function is performed by video cameras, computer equipment, and flash cards. Many companies are engaged in the production of projectors, and you need to know which of them are considered the best. Before buying, it is important to analyze the pros and cons of projection devices, to understand their features.

The list of the main features of LED projectors includes:

• brightness;
• contrast;
• service life and price of bulbs;
• installation method;
• noise level.

LED projectors have both advantages and disadvantages. The advantages of these devices include:

• compact size and light weight;
• minimum energy consumption;
• long service life;
• democratic price.

In LED projection devices, electronic components are located as tightly as possible, they do not have a lamp with heavy equipment. The design of such equipment does not provide for a spinning wheel, since the colors are changed by software. This increases the reliability of the projectors, making them lighter.

LED projection equipment is in demand among both professionals and amateurs. Its popularity is due, among other things, to the minimum power consumption. Compared to lamp devices, they consume much less energy - about 10 times. Due to this, the expenses for the use of equipment are reduced, it becomes possible to recharge it from an autonomous battery.

The resource of an ordinary lamp is 2-5 thousand hours. Much depends on the modification. LEDs are capable of functioning for about 20 thousand hours or more. The purchase of LED devices does not require significant material investments, as well as the subsequent maintenance of the equipment.

The advantages of such devices include the versatility inherent in some modifications.

Despite the numerous advantages of this technique, it has not yet succeeded in completely replacing the tube counterparts. The most significant disadvantage is the insufficient power of light radiation. Lamp models are superior to LED in this parameter. This disadvantage limits the use of LED devices in everyday life.

Projection technology based on LED technology usually projects a picture with a low resolution compared to a lamp counterpart. That's why it is undesirable to place such devices near surfaces - the scenes will be blurry.

Another drawback is associated with the high level of noise during operation - this can ruin the entire enjoyment of watching a movie. Usually this parameter is above 35 dB.

LED video projectors are usually classified into several types. Allocate models for:

• home theaters;
• business events (most often for presentations);
• cinemas and concert halls.

Diode projectors vary in cost, size and performance. Home theater devices display dynamic images, while others are suitable for playing static images. There are even models that can reproduce 3D formats. They are used both in the entertainment industry and in educational institutions for presentations.

Projectors with LEDs are classified according to the method of installation, size. According to this parameter, ultraportable, portable and stationary models are distinguished. The installation location of the device depends on its weight and dimensions.

Ultraportable models are the smallest, weighing less than 3 kg... Such devices are easy to transport and use with laptops. They are in demand at outdoor events. But in terms of power and functionality, they are inferior to larger equipment.

Portable ones weigh from 3 to 10 kg. They are actively used at home. Great for showing videos and images in small spaces.

Stationary weight exceeds 10 kg. Such equipment is mounted once, the installation is carried out by qualified specialists. Stationary projectors are in demand in cinemas.

• It is recommended to choose portable models for outdoor events. It is a great solution for organizing mobile presentations.
• It is desirable that the technique supports many formats and has additional connectors.
• The presence of an auto-correction option, which allows you to move the picture around the screen without affecting the device itself, is encouraged.
