Abstract
A point light-source includes a housing and a light-emitting circuit packaged in the housing. The housing includes an upper housing and a lower housing, and the light-emitting circuit includes a constant-current control chip and a plurality of single-color light strings. Each single-color light string is composed of a plurality of light-emitting elements connected in series. The constant-current control chip is configured to, in response to an external serial signal, generate pulse signals transmitted to each single-color light string so as to change a luminous brightness of each single-color light string correspondingly through each of the pulse signals.
