Light-emitting diode (LED) lighting lamp with adjustable light and adjustable color temperature and control method thereof

Abstract

The invention discloses a light-emitting diode (LED) lighting lamp with adjustable light and an adjustable color temperature and a control method of the LED lighting lamp. The LED lighting lamp comprises an LED lighting component module, a micro control unit (MCU) control module and a power supply module, the MCU control module is provided with external switch signal input and infrared remote signal input, and provided with Y_PWM warm color temperature control signal output and W_ PWM cold color temperature control signal output. A user can adjust the duty ratio of the Y_PWM warm color temperature control signal output and the W_ PWM cold color temperature control signal output of the MCU control module through an external switch or a remote control, and further the adjustment of the brightness and the color temperature of the LED lighting component module is achieved. By the double control mode of the remote control and the switch, different temperatures are obtained or adjusted to enable people to feel comfortable, moreover, the brightness of space can be adjusted to enable people to feel warm and sweet, not only is reliability improved greatly, but also the design is more humanized, and therefore the LED lighting lamp has good application prospects.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lighting fixture with adjustable light and adjustable color temperature and a control method. Background technique [0002] With the development of economy and society and the continuous improvement of LED lighting technology, LED lighting fixtures known as "green lighting" have been more and more widely used in people's daily life. Fast, no pollution to the environment, energy saving and other advantages, is gradually becoming the mainstream lighting fixtures, widely used in commercial lighting, decorative lighting, road lighting and indoor and outdoor lighting and other lighting fields, the LED lighting designed by the existing technology Most lamps do not have the function of adjusting color temperature and brightness at the same time. They can only adjust the brightness of a single color temperature or within a single color temperature. Moreover, the control m...

Problems solved by technology

[0002] With the development of economy and society and the continuous improvement of LED lighting technology, LED lighting fixtures known as "green lighting" have been more and more widely used in people's daily life. Fast, no pollution to the environment, energy saving and other advantages, is gradually becoming the mainstream lighting fixtures, widely used in commercial lighting, decorative lighting, road lighting and indoor and outdoor lighting and other lighting fields, the LED lighting designed by the existing technology Most lamps do not have the function of adjusting color temperature and brightness at the same time. They can only adjust the brightness of a single color temperature or within a single color temperature. Moreover, the control methods of existing products are relatively simple, mostly remote control. Once the remote control device is damaged, is there any other way? If the corresponding control method is used as a backup, it will bring inconvenience to people's lives. In view of the above defects, it is necessary to propose new improvements to the design of existing LED lighting fixtures
