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 ,
During our work, many customers complaint our Samsung LED are so expensive. Even some customers told us that they received cheap Samsung LED. Before shipment, customer told me that their supplier guaranteed that it is Samsung led. After receiving and check it, they found that they are fake Samsung LED. The fake Samsung led has
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
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
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
Different manufacturers produce the LED Products and they have different degree of light decay. It has something to do with the temperature. and the detarmind factors are the led chip, phosphor and packaging technolgies. Currently, the White LED light decay may be one of the most important issule to enter into the led lighting market.
