  • MULTI-FIELD ARRANGING METHOD OF LED CHIPS UNDER SINGLE LENS
    Publication number: 20110171765
    Abstract: A multi-field arranging method of LED chips under a single lens includes the steps of: setting a first concentric circle on a bottom of a hemispherical lens, wherein the first concentric circle is centered at an axis of the hemispherical lens; and equidistantly arranging at least one first color chip, at least one second color chip and at least one third color chip on the first concentric circle in sequence. The present invention allows the color chips to present symmetrical light patterns through the hemispherical lens, thereby obtaining a light field with evener color mixture.
