In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of toning dimming drive power, including civil power, also include touch panel and LED lamp, described touch panel is provided with the first rectification module, first filtration module, reduction voltage circuit module and touch-control module, linear constant current chip and LED load it is provided with in described LED lamp, the input of the first rectification module is electrically connected with city, the outfan of the first rectification module successively with the first filtration module, reduction voltage circuit module is connected with touch-control module, touch-control module is connected with LED load by linear constant current chip.
The second rectification module and the second filtration module it is additionally provided with in described LED lamp, the input of described second rectification module is electrically connected with city, the outfan of described second rectification module and the input of the second filtration module are connected, and the outfan of described second filtration module is connected with linear constant current chip, LED load respectively.
Described touch-control module is provided with light modulation region, toning region and switch region.
Described touch-control module includes touch switch, and described touch switch uses capacitor type touch switch.
Described touch-control module passes through I2C bus transfer to linear constant current chip.
This utility model compared with prior art has the advantages that
1, this utility model one toning dimming drive power, including civil power, it is characterized in that: also include touch panel and LED lamp, described touch panel is provided with the first rectification module, the first filtration module, reduction voltage circuit module and touch-control module, is provided with linear constant current chip and LED load in described LED lamp;In this utility model, civil power enters touch-control module after the first rectification module, the first filtration module, reduction voltage circuit resume module, after people touch touch-control module, touch-control module transfers signals to linear constant current chip by I2C bus, linear constant current chip carries out light modulation toning to LED load, use the control chip of linear constant current, increase the service life of light fixture.
2, this utility model touch-control module includes touch switch, and touch switch uses capacitor type touch switch, and soft-touch control can be embedded in wall, consistent with traditional approach, is unlikely to significantly to change the occupation mode of people, and easily loses unlike remote controller.
