Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] The driving circuit of the intelligent control lighting appliance of the present invention does not use the driving IC chip, but uses the internal software algorithm of the single-chip microcomputer combined with the peripheral circuit to realize the intelligent control of the lamp, and directly outputs the driving signal through the I / O port of the single-chip microcomputer to conduct the MOS tube of the step-down circuit The time is adjusted to realize the control of the load current or voltage, so as to realize the control of the color temperature and brightness of the lamp, and the adjustment accuracy is high. The feedback signal is also adjusted and fed back through the single-chip mi...

Abstract

The invention discloses a driving method and circuit of an intelligent control lighting appliance. Intelligent control of a lamp fixture is driven without using a driving IC chip, driving signals are directly output through the I / O port of a single-chip microcomputer for adjusting the conduction time of MOS tubes of voltage reduction circuits so as to realize control of current or voltage of a load, accordingly, the color temperature and the brightness of the lamp fixture are controlled, the adjustment precision is high, feedback signals are adjusted and fed back also through the single-chip microcomputer so as to realize stable output at a load end, the color temperature and the brightness of the lamp fixture can also be adjusted through a wireless control scheme, the circuit is simple, the cost is low, the size is small, the installation is convenient, and the application prospect is good.

Description

technical field [0001] The invention relates to a driving method and circuit for an intelligently controlled lighting appliance, belonging to the technical field of lighting applications. Background technique [0002] With the maturity of LED lighting application technology, intelligent control lighting fixtures are gradually emerging in the lighting industry. LED intelligent control lighting fixtures give full play to the characteristics of the LED light source itself. Users can control the lighting status of the fixtures at will through the remote control. At present, some driving schemes of LED intelligent control lighting appliances on the market control part of the MCU chip to send a signal to the driver IC chip, so that the driver IC chip outputs the corresponding PWM to adjust the conduction time of the MOS tube in the driver circuit, and realize the control of the load. The current or voltage control of the part (light source part), and the signal fed back to the dri...
