Scientific and technological development along with the changing times, life gradually also have changed, we began to pursue the quality of life, and hope that life is full of all kinds of wonderful, and took full-color LED energy-savi ng lamps for example, this is nowadays the most welcome energy-saving equipment, much to everyone\\ s favor, the following we take a look at it.
The most critical components of the full color led display LED lamp. There are three reasons:
First, LED lamp beads using the largest number of key components in full color LED display machine, per square meter will be used only a few thousand to tens of thousands of LED lamp;
Second, LED lamp beads is to determine the performance of the main optics of the entire screen, a direct impact on the audience led display showing the effect of evaluation;
Third, LED lamp beads in the LED display in the overall cost of the largest proportion, ranging from 30-70%.
The quality and parameters of the full color LED display LED lamp can be attributed to the following five elements:
1, the failure rate
The full-color LED display by the tens of thousands or even hundreds of thousands of clusters of red, green, blue three LED lamp composed of pixels composed of any one color LED lamp failure will display the overall visual effect.
2, the antistatic ability
LED lamp, semiconductor devices sensitive to static electricity can easily cause static failure, antistatic ability is critical to the life of the led display. In general, the LED lamp bead body static mode test failure voltage should not be less than 2000V.
3, the attenuation characteristics
Red, green and blue LED lights beads were attenuation characteristics with the increase of working time and the brightness. The pros and cons of the LED chip, The quality of the auxiliary materials and packaging technology level of the decay rate of the LED lamp.
4, the brightness
LED lamp brightness is an important determinant of the whole screen brightness of the LED display. The higher the brightness, LED lamp, LED lamp bead stability is good. LED lamp has a different angle values, the case of chip brightness has been set, the smaller the angle, LED lamp beads, the more light, but the smaller the perspective of the LED display. Should generally be 100 degrees -110 degrees LED lamp in order to ensure adequate perspective of the LED display. For different spacing and different line of sight of the LED display brightness, angle, and the price to find a balance.
5, consistency
The full color LED display makes up an unlimited number of pixels of red, green and blue LED lamp, the brightness of each color LED lamp, the consistency of the wavelength of the LED display brightness consistency, white balance consistency color consistency.
led energy saving lamps can bring to life more exciting, allowing you to live in a different light, according to the day of his mood changes to select the color of lights, is not thought very excited about it? !
