Description
Technical Field

Background
A light emitting diode, which is simply referred to as an LED, is one of semiconductor diodes made of a compound containing gallium, arsenic, phosphorus, nitrogen, etc., which can convert electric energy into light energy, and which can radiate visible light when electrons are recombined with holes, and thus can be used to make a light emitting diode. As indicator lights in circuits and instruments, or as a text or numerical display. Gallium arsenide diode Guan Fa red light, gallium phosphide diode Guan Fa green light, silicon carbide diode yellow light and gallium nitride diode blue light. Because of the chemical properties, the organic light-emitting diode OLED and the inorganic light-emitting diode LED are divided, and the light-emitting diode is composed of a PN junction like a common diode and also has unidirectional conductivity. When a forward voltage is applied to the light emitting diode, holes injected from the P region to the N region and electrons injected from the N region to the P region recombine with the electrons in the N region and the holes in the P region within several micrometers near the PN junction, respectively, generating spontaneous emission fluorescence. The energy states of electrons and holes in different semiconductor materials are different. The more energy released when the electrons and holes recombine, the shorter the wavelength of the emitted light. The LED light source is a light source with a Light Emitting Diode (LED) as a luminous body, and has the characteristics of high efficiency and long service life. The LED light source mainly comprises a ring light source, a strip light source, a linear light source, a back light source, an outer coaxial reflection light source, an inner coaxial point light source, a hemispherical ridge cover light source and the like, and the color rendering property refers to the characteristic that different light sources with different spectrums show different colors when irradiated on an object with the same color. The color rendering of a light source is generally represented by a color rendering index (Ra). The higher the color rendering index of the light source is, the better the color rendering performance is, the better the color reproduction of the light source with high color rendering is, the color seen by the light source is closer to the natural primary color, the color reproduction of the light source with low color rendering is poor, the color deviation seen by the light source is larger, and the general color rendering index of the light source is not lower than 90 in places with high color differentiation requirements such as display drawing, colored fabrics and other multicolor exhibits. For places with low color discrimination requirements, the general color rendering index of the light source should not be lower than 80. Therefore, a high color rendering index generally means a color rendering index of 90 or more.
