LED illumination and Color Knowledge

LED illumination(E, Illuminance): formerly called lux. it is the illumnance that 1 lumen evenly distributed on the surface of one square meter generated . We usually seldom use this parameter, so here we don't explain more . Color : The color rendering index indicate that an object represents the itself color of the light ,

LED CRI — LED Knowledge

The colour rendering index (CRI) is a measure that has been widely adopted and used by the lighting industry to characterise the quality of a light source.    CRI is a specification to assist designers in making comparison between different lamp sources and is a relative comparison between a lamp source and a reference source. It

LED Color — LED Knowledge

LEDs are highly monochromatic, emitting a pure color in a narrow frequency range. The color emitted from an LED is identified by peak wavelength (lpk) and measured in nanometers (nm ). Peak wavelength is a function of the LED chip material.  Although process variations are 0 NM, the 565 to 600 NM wavelength spectral region

LED Color Temperature — LED Knowledge

A measure of the distribution of power in the spectrum of white, or colorless, light, stated in terms of the kelvin temperature scale.    The human visual system is incredibly adept at quickly correcting for changes in the color temperature of light; many different kinds of light all seem "white" to us. Photographic film is
