Abstract

The invention discloses a logic gate control LED system based on linear driving. The logic gate control LED system based on linear driving is mainly composed of a front-end rectification filter circuit, a voltage transformation circuit connected with the front-end rectification filter circuit, a fine adjustment circuit connected with the voltage transformation circuit, a voltage detection circuit connected with the voltage transformation circuit, a logic control circuit connected with the fine adjustment circuit, and an output circuit connected with the logic control circuit. The logic gate LED system based on linear driving is characterized in that a linear driving circuit is connected between the voltage transformation circuit and the fine adjustment circuit and is composed of a driving chip U2, a triode VT3, a triode VT4, a triode VT5, a triode VT6, a polar capacitor C6 and the like, the positive electrode of the polar capacitor C6 is connected with the voltage transformation circuit, and the negative electrode of the capacitor C6 passes through a resistor R6 and then is connected with an IN1 pin of the driving chip U2. According to the logic gate control LED system based on linear driving, due to the fact that the linear driving circuit is arranged, the LED system can be driven more stably.

Description

technical field [0001] The invention relates to an LED drive system, in particular to an LED logic gate control system based on loss suppression. Background technique [0002] As a new type of energy-saving light source, LED lights have been widely accepted and adopted by people due to their environmental protection, energy saving, long life, and small size. Since LED is a sensitive semiconductor device and has negative temperature characteristics, the LED voltage detection circuit plays a very important role in promoting the LED to be in a stable and reliable working state during the application process. [0003] However, the currently used LED drive system is susceptible to interference from the internal or external environment of the system, which affects the normal driving of the LED lamp by the system and causes the LED lamp to not work normally. Thereby affecting people's normal activities, and also affecting the service life of LED lights. Contents of the invention...
