LED Christmas light string with IC chip controlling light emitting

Abstract

The invention discloses an LED Christmas light string with an IC chip controlling light emitting and belongs to the technical field of decorative lighting. The LED Christmas light string comprises a transformer, a controller, a normally-on LED light-emitting branch circuit and a controllable LED light-emitting branch circuit. The output end of the transformer is connected with the input end of the controller, and the output end of the controller is respectively connected with the normally-on LED light-emitting branch circuit and the controllable LED light-emitting branch circuit. The Christmas light string with the IC chip controlling light emitting is simple in structure and reasonable in design. Through control of an IC module, point control of an LED lamp requiring light-emitting mode variation in the controllable LED light-emitting branch circuit is achieved, and rich variation of light-emitting effects of the controllable LED lamp string is achieved without a special LED lamp. The LED Christmas light string with the IC chip controlling light emitting is a revolution in Christmas lamp strings and faced with an enormous consumer market.

Description

Technical field [0001] The invention belongs to the technical field of decorative lighting, and specifically relates to an LED Christmas light string with IC chip controlled light emission. Background technique [0002] LED string lights are the main decorations for Christmas, and they are also indispensable lighting decoration electronic products for the general public's celebrations, homes, stores, cultural activities, and night scene projects in public places. It has a broad market. [0003] At present, there are two lamp string modes: always on and flashing. The constant light mode is simple to manufacture and relatively monotonous; there are two types of flashing lights: one is to install LED flashing bulbs in series on the basis of the constant light string, but this kind of flashing bulb lighting mode is fixed, that is, constant frequency The flashing of the flashing bulb will not produce other changes. Moreover, when the flashing bulb flashes, it will affect other always-o...

Problems solved by technology

The constant light mode is simple to manufacture and relatively monotonous; there are two types of strings with flashing lights: one is to install LED flashing bubbles in series on the basis of the constant light strings, but the mode of this flashing light is fixed, that is, constant frequency The flickering will not produce other changes. Moreover, when the flashing bulb flickers, it will affect other constant light bulbs on the same string unit, so that other constant light bulbs will also flash synchronously and oppositely; the other is that the light string is divided into Several groups, the lamp group that requires a change in the lighting mode is controlled by a separate controller. The characteristic of this change is that all the bulbs on the same group change synchronously, and it is impossible to achieve the non-synchronous randomness of each LED bulb that requires the change.
