Power circuit of energy-saving lamp

Abstract

The invention discloses a power circuit of an energy-saving lamp. The power circuit comprises a voltage stabilization circuit, a voltage reduction and rectification module, a control module, an amplifier circuit, a switch and a human body induction module, wherein an input end of a voltage stabilization module is connected with a mains supply, an output end of the voltage stabilization module is connected with the control module and the human body induction module, the human body induction module is used for acquiring a human body signal and transmitting to the amplifier circuit, the amplifier circuit is used for amplifying an input signal and outputting the input signal to the control module, the control module is also connected with a switch. In the power circuit of the energy-saving lamp, a human body induction technology is employed and combined with a light-control technology to achieve energy-saving control of an LED lamp; compared with sound control and touch control, the power circuit is more convenient and accurate, large noise is not needed to be made at night to affect people, a user also does not need to seek for the switch in the dark, and the safety is improved; and the control circuit employs a micro-power consumption complementary metal-oxide-semiconductor (COMS) integrated voltage stabilization circuit MAX666 as a control component, the power circuit is stable to work and is small in static power consumption, and electric energy waste is prevented.

Description

technical field [0001] The invention relates to a power circuit, in particular to an energy-saving lamp power circuit. Background technique [0002] Due to the advantages of low cost, long life, small size and high brightness, white LEDs are rapidly applied to the field of lighting, especially in outdoor lighting, especially the voice-activated lights that have been promoted in recent years, which are easy to use and save power. At present, the control circuits of most lighting lamps on the market are controlled by relays, so there is a large static loss, so it has yet to be improved. Contents of the invention [0003] The object of the present invention is to provide an energy-saving lamp power supply circuit with various functions and low static power consumption, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A power supply...
