Since red (R) and blue (B) LED light has different quantum efficiency and photoelectric conversion efficiency, mixed RB with different proportions of R and B results in varied energy consumption. In order to improve the energy use efficiency of the close
Sunlight contains different colors of light — red, orange, yellow, green, blue,indigoandviolet. These colored lightrayshave differentwavelengthsand different energy levels. Blue wavelengths are good for people during daylight hours. They ca...
Blue light, being of short wavelength, is scattered more efficiently than light of longer wavelengths. Although waters of the open ocean are commonly some shade of blue, green water is commonly seen near coasts, especially in tropical or subtropical regions. This is caused by yellow pigments ...

Visible blue light is the portion of the visible light spectrum that has the shortest wavelengths and highest energy. Ad According to All About Vision, “Blue light generally isdefinedas visible light ranging from 380 to 500 nm. Blue light is sometimes further broken down into blue-violet light...
It’s also known thatwomen can see more differentiations in color than men. It’s science! Color vision depends on three types of cones, two of which are carried on the X-chromosome. L-cones that are more sensitive to the longer wavelengths of light; and S-cones, to shorter wavelengths...
Under appropriate conditions, visible to near-infrared light irradiation exerts wound-healing, anti-inflammatory, anti-edema, and hair growth-promoting effects [1]. This phenomenon is called photobiomodulation (PBM). Light sources with wavelengths in the 400 nm range are used to treat psoriasis vul...
This side effect is associated primarily with the presence of an absorption tail which extended over the longer wavelengths relative to the plasmonic absorption peak (Figure 3a). Somewhat less emission loss of red relative to green color is also understandable from the spectral attenuation of an ...
Each color in the visible light spectrum has a different wavelength and energy level. Blue light has shorter wavelengths and higher energy than other colors. The approximate wavelength ranges (in nanometers) for visible light is: Red: 650 ...
since the wavelength of the blue light passes through the particles with greater ease than the wavelengths of the other colors of light, the sky appear blue to the naked eye.这种现象说明了光线通过地球大气微粒时的物理散射方式。大气微粒的直径为有色光直径的十分之一。光谱是按波长由红...
