LED dimming driving device and dimming LED lamp

Abstract

The invention belongs to the technical field of lighting lamp control, and relates to an LED dimming driving device and a dimming LED lamp with the same; and the LED dimming driving device and an on-off switch control and regulate the brightness or color changes of the LED lamp. The invention provides the LED dimming driving device which comprises a first power supply circuit, a single-chip microcomputer and a second power supply circuit; the single-chip microcomputer is used for controlling the first power supply circuit to supply power to the LED and supplying power to the single-chip microcomputer; the second power supply circuit is used for supplying power to the single-chip microcomputer after the first power supply circuit stops supplying power; and the single-chip microcomputer is used for acquiring and analyzing the on / off signal of the first power supply circuit, and selecting and outputting an LED control signal which corresponds to the on / off signal.

Description

【Technical field】 [0001] The invention belongs to the technical field of illumination lamp control, and relates to an LED dimming driving device and a dimming LED lamp provided with the dimming driving device. The LED dimming driving device controls and adjusts the brightness or color of the LED lamp together with an on-off switch. Variety. 【Background technique】 [0002] Compared with ordinary fluorescent lamps or tungsten-halogen lamps, the advantages of LED lamps are not only their high luminous efficiency and long service life, but also their good color rendering, which can display a variety of different colors. In the prior art, the color control of LED lighting lamps is mainly controlled by a remote controller. The remote controller is equipped with a control circuit board and control buttons. The control buttons are used to select different color change drivers for LED lights, and the control commands are sent wirelessly. To the LED light driving circuit at the recei...

AI Technical Summary

Problems solved by technology

[0003] Controlling the color change of LED lights through this control method will increase a lot of costs, such as increasing the cost of wireless transmitting and receiving modules. Although the color change of LED lights can be controlled remotely through wireless, it increases the convenience for people to control LED lights, but In real life, the remote control has the problem of being difficult to keep and often lost

[0004] Even if there is another control method that does not use a remote controller to control the LED lamp, but directly connects the control circuit board to the drive circuit of the LED lamp through wires, including the key board of the control circuit board fixed on the wall or other objects, but Such a control method cannot save the control cost very much, and it increases the inconvenience of engineering installation, and on the other hand, it also brings inconvenience to users in regulation.
