Light emitting diode (LED) healthy lighting lamp

Abstract

The invention discloses a light emitting diode (LED) healthy lighting lamp. The LED healthy lighting lamp comprises an LED light source, an LED lamp fixing plate, a voltage stabilization power supply, a single-chip microcomputer, an input circuit, a voltage sampling circuit, a pulse width regulation circuit, a driving circuit and a self-detection circuit, wherein the single-chip microcomputer, the input circuit, the voltage sampling circuit, the pulse width regulation circuit, the driving circuit and the self-detection circuit are separately connected with the voltage stabilization power supply, the voltage sampling circuit is used for acquiring a voltage change signal of the LED light source and the inputting the voltage change signal to the single-chip microcomputer, the single-chip microcomputer is used for generating a control signal for adjusting the pulse width regulation circuit according to the voltage change signal, and the input circuit is used for inputting the control signal to the single-chip microcomputer. In the LED healthy lighting lamp, the single-chip microcomputer is taken as the control circuit to control the working condition of the LED light source, the LED light source is regulated by an infrared remote controller or a microwave induction circuit, and the adjustability of color temperature and luminous color of the lamp is achieved; and meanwhile, the voltage stabilization power supply is self-detected by the self-detection circuit, whether a fault occurs in the voltage stabilization power supply or not can be automatically detected, and a user is timely reminded of the circuit state.

Description

technical field [0001] The invention relates to the field of lighting and control, in particular to an LED health lighting lamp. Background technique [0002] LED is the core device of semiconductor lighting. Because it emits light from a PN junction, it has many advantages such as high brightness, high light efficiency, long life, and environmental protection. Its application has developed rapidly in recent years. Especially after the successful research and development of gallium nitride (GaN)-based blue LED light-emitting devices, the technology and industry of white LEDs based on blue chips have developed rapidly. [0003] However, the color temperature and luminance of the existing lamps are generally fixed. This kind of lamp is only suitable for single lighting applications. Generally, the control of the brightness of the lamp is realized by adjusting the size of the current. Relatively simple, this kind of lamp has few optional colors, and has the disadvantages of si...
