Point contact switch input single-chip microcomputer controlled double-path light and color adjusting method and two-way light and color adjusting system

Abstract

The invention discloses a point contact switch input single-chip microcomputer controlled double-path light and color adjusting method and double-path light and color adjusting system. The system comprises a switch for starting an LED light source, a programmable controller judging triggering conditions for single click, long press and double click, a double-path light and color adjusting device which comprises a first set of light adjusting assembly and a second set of light adjusting assembly, and outputs the changed working power PWM1a of the first set of light adjusting assembly and the working power PWM2a of the second light adjusting assembly, and an LED light source which receives the working power PWM1a of the first set of light adjusting assembly and the working power PWM2a of thesecond set of light adjusting assembly which are output by the double-path light and color adjusting unit so as to be turned on. According to the point contact switch input single-chip microcomputercontrolled double-path light and color adjusting method and double-path light and color adjusting system of the invention, turning on, turning off, color adjusting and color temperature adjustment arerealized through single-click, long-press and double-click actions, and automatic memory and storage are realized; as switching signals only need alternating current input, the problem of signal interference is avoided, the practicability and convenience of the light adjusting method are greatly improved, and the light adjusting method has outstanding substantial advantages.

Description

technical field [0001] The invention relates to the technical field of LED light sources, in particular to a two-way dimming and color adjustment method and system controlled by a point-touch switch input by a single-chip microcomputer. Background technique [0002] LED has the characteristics of energy saving, environmental protection, long life, small size, etc., and is widely used. People hope to be able to adjust the brightness of the light source during use, which not only saves energy and reduces waste, but also avoids long-term overloading of LED lights. Improve the operating efficiency and service life of the LED. [0003] At present, with the improvement of the quality of life, it is necessary to create different lighting atmospheres, not only dimming, but also different color temperature requirements. For example, the currently popular CW two-tone lighting. At present, the control of the mainstream two-color temperature dimming system is completed by mobile phone...

AI Technical Summary

Problems solved by technology

At present, the control of the mainstream two-color temperature dimming system is completed by mobile phone APP or wireless remote control; one is high cost; the other is that the mobile phone needs to install software, which is very troublesome; especially the most important remote control and mobile phone are not fixed, and you need to look for it everywhere when you need it.
