Abstract: The disclosure provides a lamp bead and a lamp strip. The lamp bead includes a packaging housing, one or more LED lamps and an LED lamp driving chip; the LED lamps and the LED lamp driving chip are arranged in the packaging housing; and a power positive pole connection terminal, a signal connection terminal and a power negative pole connection terminal which are arranged longitudinally are exposed on an outer side of the bottom of the packaging housing. In the disclosure, through the packaging structure of the power positive pole connection terminal, the signal connection terminal and the power negative pole connection terminal which are arranged longitudinally, during wiring, power positive pole connection terminals of all beads are in a straight line, power negative pole connection terminals thereof are in a straight line, and signal connection terminals thereof are in a straight line.

Abstract: The present invention discloses a cyclone generator for a pipeline type oil-water separator which separates oil from water using the principle of cyclone. The cyclone generator comprises: flow deflectors which are fixedly arranged along the circumferential direction of a pipe to generate, when an oil-water mixture flows through the flow deflectors, a centrosymmetric cyclone field to centrifugally separate oil from water. The present invention further discloses an oil-water separation device which uses the aforementioned principle, the mixture of oil and water flowing through the device forms a centrosymmetric cyclone field in which an oil core is distributed in the central area of a pipe without shifting significantly so as to achieve an excellent oil-water separation effect.
