SURFACE-MOUNTED LIGHT-EMITTING DIODE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a surface-mounted LED element allowing light extraction efficiency of the overall element to be improved by reducing the thickness of a phosphor-mixed layer to minimize loss of energy of light emitted from an LED chip and permeating the phosphor-mixed layer.SOLUTION: The surface-mounted LED element is formed by including: a package which houses one or more pairs of electrodes inside, and is formed by having a predetermined space at the center, and having an emitting window opened to emit light; a lens which is formed on the package to cover the emitting window; the LED chip mounted on the electrodes inside the package; wires for electrically connecting the LED chip to the electrodes; and the phosphor-mixed layer which is formed on the surface of the lens adjacent to the emitting window.
