What is RGBLED lamp beads? How is the synthetic light produced? Both RGBLED lamp beads and white light LED lamp beads actually hope to achieve the effect of white light, but one is directly presented with white light (phosphor), and the other is based on Mixed light of red, green and blue.
The imaging principle of RGB lamp beads: RGB lamps are integrated with the three primary colors. In addition, there are blue LEDs with yellow phosphors, and UV LEDs with RGB phosphors. On the whole, both have their imaging principles, but they have attenuation problems. The effects of ultraviolet rays on humans are both difficult to solve in the short term. Therefore, although both can meet the needs of white light, they have different results.
The application of RGB lamp beads is obviously more diverse than that of white LEDs. For example, he gave examples, such as car lights, traffic signs, shop windows, etc. When a certain band of light is needed, the color mixing of RGB lamp beads can be as desired. , White LED is more disadvantaged, so of course it is stronger in effect. On the other hand, if RGB LED lights are used in lighting, they will suffer a lot, because they mainly depend on the luminous flux, life and pure color of white light when used in lighting. At present, RGB LED lamp T beads are mainly used for decoration. Light aspect.
Seeing that white LEDs using phosphors have no bright future, Lin Zhuxuan, general manager of Meiguangyuan, who has already announced the abandonment of this production line, specifically stated that it is not only the problem of light attenuation, but other problems are also a major cause. He clearly stated that the clarity and color purity of white LEDs are obviously inferior to that of RGB. He also said that when RGB lamp beads overlap properly, the overall brightness and clarity of phosphor white LEDs are five. In addition, the problem of light attenuation and the high cost of wafers are also a major reason why he is optimistic about RGB lights.
Those who like high picture quality should not be difficult to find that the colors of some LE backlight panels are particularly clear and vivid, even to the extent of high-definition TVs. This situation is the characteristic of RGB lamp beads. The advertised red is red. , Green is green and blue is blue. In the light mixing, it has more diversified characteristics, just like a painter's palette, it perfectly presents the most real color world and makes a beautiful life.
When the RGB lamp beads are separated, it can be controlled separately. Although it can be directly controlled and the color mixing is also good, it is a big problem to achieve the white light of the mixed color. Although it is expensive, the quality is relatively good. As for the white LED lamp Although the cost is cheap, it can directly replace CCFL and become the main technology of LED, but relatively speaking, because of the problem of wavelength and frequency, it is packaged together, so the scattering situation will be unstable.
