Description:
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 a plurality of pulse signals to be transmitted to respective ones of the plurality of the single-color light strings so as to change a luminous brightness of each single-color light string correspondingly through a respective one of the plurality of the pulse signals.The housing includes a cover and an inner shell covered onto the cover; a convex lens is integrally formed with the cover; and a light-emitting unit electrically-connected to the light-emitting circuit is arranged such that light emitted by the light-emitting unit is collected by the convex lens and transmitted to the outside through the convex lens.
