Abstract

A chip-on-board type photoelectric device exemplarily includes: a package substrate, provided with a chip mounting region, a first electrode and a second electrode, the first and second electrodes being arranged spaced from each other at a periphery of the chip mounting region; first photoelectric chips, arranged in the chip mounting region to form inwardly concave strip-shaped patterns as mutually spaced first color temperature regions, and electrically connected between the first and second electrodes to form at least one first photoelectric chip string; and second photoelectric chips, arranged in the chip mounting region to form second color temperature regions. A light-emitting color temperature of each the second color temperature region is higher than that of each the first color temperature region. The second photoelectric chips are electrically connected between the first and second electrodes to form second photoelectric chip strings. A good uniformity of light mixing can be achieved.
