Light control device and lamp strip

Abstract

The embodiment of the invention discloses a light control device. The device comprises a plurality of cascaded control circuit units, and each control circuit unit comprises a conduction module, a switch control module and a light source group; the conduction module is connected with the switch control module; the switch control module is connected with the light source group; and the switch control modules of the control circuit units are mutually connected in parallel, the light source groups are mutually connected in parallel, and the conduction module are subsequently connected in series.In addition, the embodiment of the invention also discloses a lamp strip. By implementing the embodiment of the invention, the lamp strip or a lamp string light source is controlled by adopting fewerand simple electronic elements, the time sequence flow of the light is realized, and the cost can be reduced; and connecting wires among unit circuits are fewer so as to carry out mutual cascade connection conveniently; and simultaneously the unit circuits are not mutually interfered and can accurately control the light.

Description

technical field [0001] The invention relates to the field of light-emitting advertisements, in particular to a light control device and a light strip. Background technique [0002] Neon lights are usually used for decoration on city streets, bridgeheads, building outlines, advertising boards, etc. In order to increase the beautification effect, after installing a controller, the colored light strips or light strings can be turned on and off sequentially at different time intervals, which will make people Produce the visual effect that the lights are flowing or running and moving. [0003] When the existing neon light control device controls the "brightness" and "darkness" of the LED light source, multiple, multi-row single-chip microcomputers are used to make multiple, multiple, clusters, or according to a certain pattern, pattern sequence or timing by setting corresponding programs. "On" and "off" automatically realize the flow of LED light sources or the transformation of...

Problems solved by technology

[0003] When the existing neon light control device controls the "brightness" and "darkness" of the LED light source, multiple, multi-row single-chip microcomputers are used to make multiple, multiple, clustered, or follow a certain pattern, pattern sequence or timing by setting corresponding programs. "On" and "off" automatically realize the flow of LED light sources or the transformation of patterns, but the existing technology uses a single-chip microcomputer for control, resulting in complicated wiring and troublesome wiring connections, which cannot be cascaded with each other, and cannot be applied due to high costs. into small light strips
