Are all white LEDs blue? No, not all white LEDs are blue. The light-emitting mode of white light LED can be divided into two types: single-crystal type and polycrystalline type according to the number of LED light-emitting diodes used. One is the polycrystalline type, that is, two or more complementary 2-color LED light-emitting diodes or 3-primary-color LED light-emitting diodes are used as mixed light to form white light. The polycrystalline type generates white light. This method is better than The single-crystal type LED that generates white light in a complicated manner, and because of the large number of LED light-emitting diodes, the cost of the polycrystalline type LED is also higher. The other is a single crystal type, and two methods are usually used. One method is that a blue LED light-emitting diode excites the yellow phosphor to produce white light, and the other method is an ultraviolet LED to excite RGB three-wavelength phosphors to produce white light. But over time,…
