High-sensitivity and multi-functional control system for multi-circuit light emitting diode (LED) lamp

Abstract

The invention discloses a high-sensitivity and multi-functional control system for a multi-circuit light emitting diode (LED) lamp. The high-sensitivity and multi-functional control system is characterized by mainly comprising a singlechip, a power supply, an infrared detector, a brightness sensor, a displayer, a data storage device, an LED lamp, a signal amplifier, a brightness signal processing circuit, a constant-current driving circuit and a triode rectification and filtering voltage-stabilization circuit, wherein the infrared detector, the brightness sensor, the displayer, the data storage device and the LED lamp all are connected with the singlechip, the signal amplifier is connected in series between the infrared detector and the singlechip, the brightness signal processing circuit is connected in series between the brightness sensor and the singlechip, the constant-current driving circuit is connected in series between the singlechip and the LED lamp, and the triode rectification and filtering voltage-stabilization circuit is connected in series between the power supply and the singlechip. With the multi-functional control system for the LED lamp, disclosed by the invention, the stable driving current can be output, automatic control on turn-on or turn-off of the LED lamp can be achieved, thus, the energy-saving aspect of the LED lamp can be satisfied, and the requirement of intelligent control is met.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a high-sensitivity multifunctional control system for multi-circuit LED lamps. Background technique [0002] At present, 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. With the continuous improvement of people's living standards, higher requirements are put forward for the brightness and energy consumption of LED lights, whether at home or in stores, that is, people need to further increase the brightness of LED lights while requiring LED lights to have lower energy consumption. , and can intelligently control the use of LED lights. [0003] However, due to the poor stability of the control system and the unstable output drive current of the LED lights currently used by people, and the inability to realize automatic control of the...
