Everlight Electronics Co. Ltd.Request Info
 
Everlight Electronics Co. Ltd.’s multichip Yi LED lighting series offers high power, high luminosity and 5-W power consumption in a compact ceramic package. The Yi LEDs are four-chip devices with low thermal resistance as a result of the ceramic substrate. They measure 6 x 6 x 4.28 mm and are suitable for interior and exterior automotive and general illumination; for indoor, outdoor, decorative, entertainment, commercial, signal and beacon lighting; and for retrofit bulbs. With a 700-mA driving current, the LEDs can be driven at up to 5 W. Minimum flux is up to 400 lm at 6500 K correlated color temperature or 325 lm at 3000 K correlated color temperature, when driven with 700-mA current.

GLOSSARY
color temperature
A colorimetric concept related to the apparent visual color of a source (not its temperature). For a blackbody, the color temperature is equal to the temperature in kelvin.
correlated color temperature
Temperature of the blackbody having chromaticity nearest to that of the test source on a specified chromaticity diagram.
driving current
The minimum electrical current input needed to initiate lasing.
flux
Time rate of flow of energy; the radiant or luminous power in a beam.
illumination
The general term for the application of light to a subject. It should not be used in place of the specific quantity illuminance.
luminosity
Quality or state of being luminous.
thermal resistance
In a laser, a measure of the device's ability to dissipate internally generated heat.
