Abstract

A pulse width module (PWM) dimming and color modulation LED lamp comprises a mobile phone APP module, a Bluetooth communication module, a digital-analog converter, a PWM control module and an LED lamp, wherein the LED lamp is a RGB LED lamp, the mobile phone APP module is in wireless connection with the Bluetooth communication module, the Bluetooth communication module is connected with the digital-analog converter, the digital-analog converter is connected with the PWM control module, and the PWM control module is connected with the LED lamp and is used for adjusting color and brightness of the LED lamp by changing a duty ratio of the LED lamp. The corresponding duty ratio can be reversely calculated by directly inputting a corresponding parameter into required LED light via an algorithm chip and circuit, the color and the illumination are dynamically adjusted on the condition of adjusting the duty ratio, PWM dimming has the advantages of more accurate dimming, more rapid color change, more vivid dimming color and more color change of a dimming mode compared with a traditional mode, and meanwhile, the lamp is low in heat generation and higher in efficiency.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a PWM dimming and color LED lamp. Background technique [0002] Smart home appliances are home appliance products formed by introducing microprocessor, sensor technology, and network communication technology into home appliances. Remote control instructions; at the same time, as a component of smart home, smart home appliances can be connected with other home appliances, homes, and facilities in the house to form a system to realize smart home functions, and this forms one of the most specific applications in the Internet of Things. With the continuous development of human application needs and intelligent home appliances, its content will be more abundant, and the smart home appliances that can be most integrated into human daily life are LED lamps. Of course, the functions of different smart home appliances will vary according to the actual application environment. However, smar...
