Technology is people-oriented, and the "full spectrum" concept that has become popular in the lighting industry in recent years can be said to be the most phenomenal product that embodies this concept. Many people even name it when decorating and want to install full-spectrum lamps. So how should we understand the concept of full spectrum? What about concepts?
1) First, let's talk about the spectrum. Anyone who has played with a prism knows that light can be decomposed into a series of monochromatic lights due to dispersion. The spectrum is a band of light that is divided into a series of monochromatic light after being split by a dispersion system (such as a prism and a grating), and then arranged in order according to the wavelength.
2) However, different lights have different energy distributions in the spectrum, and the proportions of components of various wavelengths will be different. Sunlight has an extremely broad continuous spectrum, and 99.9% of the energy is concentrated in the infrared, visible and ultraviolet regions.
The "full spectrum" in lighting fixtures refers to the light emitted by the fixture. Its spectrum is close to the solar spectrum. Especially in the visible part, the proportion of various wavelength components is similar to that of sunlight. The color rendering index of the light is close to that of sunlight. Color rendering index.
3)Strictly speaking, incandescent lamps are also considered full spectrum. Because the spectrum of incandescent lamps is continuous and covers the visible light region, incandescent lamps have a high color rendering index and can reflect the true color of the object being illuminated. However, due to the two fatal shortcomings of incandescent lamps: low light efficiency and short lifespan, incandescent lamps are "expensive". Even incandescent lamps with good light color have been replaced by a new generation of green light sources.
4) In recent years, the development of LED has made breakthroughs, breaking the barrier of key technologies. People have upgraded the traditional LED technology of using blue LED to excite phosphors to using purple LED to excite phosphors to obtain red, green and blue colored lights. After the color lights are mixed and superimposed, they produce Light with a similar spectrum to sunlight. This technology combines the technical characteristics and product advantages of LED itself to make full-spectrum LEDs more in line with the needs and trends of the lighting market, so full-spectrum LEDs are also very popular.
