The spectral composition of each type of light is different , and today I will share with you the light spectrum of various types of lighting .

　　All of us in the flat during their daily lives, as seen in the light most are white , even though we are the first eye looks and feels light color seems a bit yellowish or bluish, but in fact their essence on all white light.

　　Listed as the morning sun rises from that time until this time of the evening, we though at different times to see the sun the color seems to be constantly changing, but light in nature is actually not what the difference is.

　　The origin of the spectrum

　　Friends who have a little physical foundation understand that white light is composed of various lights mixed together, which was discovered by the great British physicist Newton. In an accidental experiment, he used a prism to diverge white light into a visible spectrum (composed of light of various colors).

　　This experiment is as shown in the figure below: a beam of white light irradiates a certain surface of the prism, passing through the prism, the white light is dispersed into light of various colors ;

　　Immediately afterwards, put a prism of the same texture behind the original prism, and you will find that the lights of various colors will converge into a beam of white light.

　　Formally because of this very simple experiment, Newton proved the theory that "white light is a mixture of various colors of light".

　　From this, we can illusion that white light is composed of light particles of many colors (which can be analogous to color balls). After distinguishing these light particles according to colors, we find that the yellow light is the most and the purple light is the least. Finally, this composition of white light is connected with lines, and it becomes the spectrum (red, orange, yellow, green, blue, indigo, and purple) that we see now.

　　Various spectra

　　The spectrum of low color temperature fluorescent lamps and high color temperature fluorescent lamps are obviously different in color temperature. Low color temperature red and yellow light have more components ; high color temperature blue and green light have more components.

LED spectrum

　　The blue light peak in the high color temperature LED spectrum is extremely high, while the yellow light peak in the low color temperature LED spectrum is the highest. This means a high color temperature LED light cool, low color temperature LED lamp warm.

　　Since white light is a mixture of colored lights of different wavelengths, we can produce any white light that meets the conditions according to different environments and needs.

Analog spectrum

　　This is an instrument for simulating spectroscopy, which is often used in the field of scientific research or mixed experiments of led packaging manufacturers. Related personnel can use this equipment to mix any spectra.

　　Not only that, it can also simulate light sources with different color temperatures. The picture below shows the same object under different color temperature light sources, and the visual effects are different.
