摘要： 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.-

摘要： A surgical lighting assembly (100) comprises an upper housing (110), with an upper rim arranged (120) around at least a portion of a perimeter of the upper housing, and a lower housing (130), with a lower rim (140) arranged around at least a portion of a perimeter of the lower housing. The upper housing and the lower housing are configured to fit together around their perimeters to define a chamber (250) therebetween. The lighting assembly further comprises a light source (270) in the chamber, a sealing member (170) located between the perimeters of the upper and lower housings, and a plurality of clamping strips (190). The clamping strips are configured to clamp the upper rim to the lower rim around the perimeter of the housings, so that the upper housing is clamped to the lower housing in a sealed configuration.
