Abstract: An LED driving device with an adjustable dimming depth is provided. The LED driving device includes an LED driver and a dimming depth control circuit. The LED driver includes a dimming control circuit and a driving circuit. The dimming control circuit generates a first pulse-width modulation (PWM) signal according to a first brightness indication signal. The driving circuit drives a first light source and adjusts a brightness of the first light source. A duty ratio of the first PWM signal and the first driving current have a first relationship therebetween. The dimming depth control circuit includes a first variable resistance circuit, and the first variable resistance circuit controls a magnitude of a first variable resistance between a first current sampling terminal and a ground terminal according to a first dimming depth control signal. The first relationship defines a first dimming depth that varies with the first variable resistance.

Abstract: The present invention relates to the field of medical technology, and in particular, to a variety of substituted N-(5-(quinolin-6-yl)pyridin-3-yl) benzsulfamide derivatives represented by formula (1) (groups therein are as defined in the specification). The compounds according to the present invention have favorable anti-tumor activity against human lung cancer, colon cancer, liver cancer, breast cancer and glioblastoma multiforme, which contribute to development of highly effective, low toxic and high specific anti-tumor drugs, and have high value of development. The present invention also relates to a composition, preparation method and use thereof in the preparation of anti-tumor drugs.
