The Effect of Infrared LED Lamp Beads on LED Display

The impact of infrared LED lamp beads on LED display 1. View angle: The perspective of the LED display determines the perspective of infrared LED lamp beads. At present, most outdoor display screens use horizontal perspective 100°; Vertical perspective 50°; The ellipse LED, the interior display screen is 120 vertical°; Patch LED. Display on highways is generally selected from 30 due to its particularity°The round LED of the perspective is enough. The display on the high -rise buildings requires high vertical perspectives. The perspective and brightness are contradictory, and the big perspective will inevitably reduce the brightness. The choice of perspective needs to be determined according to the specific purpose. 2. Brightness: LED brightness is an important decisive factor in the brightness of the display screen. The higher the brightness of the LED, the greater the balance of using the current, which is good for saving power consumption and maintaining LED stable. The LED has a different angle value. With the brightness of the chip, the smaller the angle, the brighter the LED, but the smaller the viewing angle of the display screen. Generally, a 100 -degree LED should be selected to ensure that the display screen is sufficient. For different spacing and different vision display, a balance point should be found in brightness, angle and price. 3. One efficiency: Since the full -color display is composed of tens of thousands or even hundreds of thousands of groups of red, green, and blue, the pixels are composed of pixels. The failure of any color LED will affect the overall visual effect of the display screen. Generally speaking, according to industry experience, the loss efficiency before the LED display began to be assembled to 72 hours of shipment should be less than 3 % (refers to the failure caused by the infrared LED lamp beads itself). To understand the light of infrared LED lamp beads, first of all, we must understand that (i) is a physical concept, the unit is CD. The amount of light emitting intensity indicates the agglomeration of the emitting body in space. In the simple case, it is to depict how much the light source is“Bright”Essence The performance of today's infrared LED lamp beads often measures this brightness. For example, an infrared LED lamp bead is 15000mcd, 1000mcd = 1cd, which is 15CD. The brightness of LEDs is used by MCD instead of CD directly because the early infrared LED lamp beads have a low luminescence and the brightness is darker than the illumination. Use the light light to indicate the infrared LED lamp bead“brightness”Although it is objective, there are also defects. For example, the two infrared LED lamp beads with exactly the same brightness value have a high degree of brightness. Therefore, consumers should not just pay attention to the light value value when acquiring infrared LED lamp beads, but also pay attention to comparing the viewing point. Under the same conditions, the smaller the solution, the higher the brightness in the unit. Otherwise, otherwise. In addition, there is another parameter of infrared LED lamp beads lighting intensity: the light flux of infrared LED lamp beads (F), the unit is LM, and we often use the lumens in Chinese. Light measurement. For the light source, this measurement is a huge detail that depicts the total amount of light sources. It is equivalent to the optical power. The larger the optical flux of the light source, the more light announced the light and the stronger the brightness. Regarding the infrared LED lamp beads of the same sex (the light of the light sources is launched in all directions in all directions), F = 4πI. That is to say, if the I of the light source is 1cd, the total light flux is 4πLM. If you want to be brighter, we not only need to improve the light flux, but also increase the degree of agglomeration. In fact, it is to reduce the shining area, so that we can get greater intensity.
