For buying a projector , understanding the parameters is an important part. Among them, brightness is a key indicator. When comparing the brightness of LED projectors of different brands horizontally, you will find a difference: 3LED and 4LED. So, what do the 3LED and 4LED of the projector mean, which is better?
What do 3LED and 4LED mean?
1.LED refers to the type of light source used by the projector as LED lamp.
2.3LED projector: Refers to the projector using three lamp modules, which are red, green, and blue. The color of the image imaged by the projector is completed by the three primary colors, which depends on the RGB three colors The luminous intensity of LED lights, but in fact the luminous efficiency of these triple lights is different, especially the luminous efficiency of red light is relatively low, so it will lead to insufficient brightness of the overall picture.
3.4LED projector is based on 3LED, add a group of Pump Blue LED, generally use four-channel architecture in high-quality models, such as Dangbei F3D. In this way, while increasing the cost, it not only shares the attenuation pressure of the bulb, but also improves the brightness.
3LED and 4LED, which one is better of a projector?
The emergence of the 4LED projector is naturally a compensation for the previous generation of RGB three-channel projectors. The projector manufacturers saw the deficiencies of the 3LED projectors before making improvements. With the addition of the 4LED projector with Pump Blue LED, the size of the body will increase (because heat dissipation needs to be considered), and the brightness will be significantly improved. For example, the brightness of Dangbei F3 is nearly half that of the previous generation F1. Of course, the price will rise, and the life of the light source will also be extended.
The above is the description of 3LED and 4LED. Follow-up friends who want to buy smart projectors can focus on this information. Of course, the same price projector must choose a 4LED projector with better color performance.
