Description
Technical Field

Background
In the field of LED special lighting, there are generally relatively strict requirements on its color and brightness, and the fluctuation of the LED emission wavelength is limited over the entire ambient temperature range, and the LED emission intensity cannot be significantly reduced. As the junction temperature increases, the peak wavelength of the LED emission will appear red-shifted, and in the case of poor heat dissipation conditions, the light intensity at 6000h is only half of the design value, and in order to keep the brightness of the LED for illumination substantially constant, a constant current rather than a constant voltage must be applied to the LED depending on the electrical characteristics of the LED.
For LED lighting powered by a dc power supply, a non-isolated DCDC converter is the preferred constant current driving method. In this driving mode, there are two brightness adjustment modes-linear dimming and PMM dimming. The linear dimming is to apply constant current to the LED all the time and adjust the illumination brightness of the LED by changing the magnitude of the current; the main disadvantage of linear dimming is that as the constant current value increases, the dominant wavelength drift and color temperature change of the LED, especially the white LED, occur, and the dimming range is small, and the precision is difficult to improve.
With the development of social economy and the improvement of technological strength, people have higher and higher requirements on lighting control modes, and gradually move from the traditional mechanical switch to intelligent touch control. In recent years, the application range of various touch devices is gradually widened due to the rapid development of touch technology, and touch products are gradually accepted and used by more people from electronic products such as mobile phones and cameras to industrial products such as touch switches and touch screens.
