Embodiment

[0030] like figure 1 As shown, the intelligent LED scene light dimming system of this embodiment includes an intelligent mobile terminal, a network node, a control node, a low-power DC / DC constant current output control circuit, and an LED lamp.

[0031] The smart mobile terminal is a portable mobile terminal platform for users; the network node is used as a transmission intermediary for information interaction between the smart mobile terminal and the control node; the control node is used to generate multiple PWM control signals at the same time, and the low-power DC / The DC constant current output control circuit realizes the control of LED lamps by pulse width modulation technology.

[0032] The smart mobile terminal in this example needs to install the client application program, and the client application program calculates the RGB value of the color according to the user's choice, and the smart mobile terminal sends it to the network node through wifi

[0033] The netw...

Abstract

A method of light-emitting diode (LED) lamp smart lighting adjustment comprises the following steps: users use a client application programme developed on a smart mobile terminal, and choose an arbitrary way of four lighting adjustment ways which are red green blue (RGB) lighting adjustment, color selective lighting adjustment, picture color picking, and color matching with music, the client application programme executes corresponding algorithm to transmit the got control parameters to a network node through wireless fidelity (wifi), the network node processes data and transmits the data to a control node through wireless radio frequency communication, an LED driving circuit is controlled by pulse width modulation (PWM) signals which are output by a micro controller unit (MCU) of the control node to adjust the light color and brightness of an LED scene light. A lighting adjustment system for achieving the method of LED lamp smart lighting adjustment comprises the smart mobile terminal, the network node, the control node, a low-power direct current (DC) / DC constant current output control circuit and an LED lamp. The method of LED lamp smart lighting adjustment and system for the method have the advantages of more humanization, novel lighting adjustment ways, and intelligence which enhances the visual effect of the LED sense lamp, meets the requirements of application intellectualization and the like.

Description

technical field [0001] The invention relates to an LED dimming control technology, in particular to an LED lamp intelligent dimming method and system thereof. Background technique [0002] With the development of social economy, the demand for energy saving and low consumption has made LED lights widely popularized and applied, and the application of LED-based light sources has also increased. The application of LED intelligent lighting in smart homes and other fields has also gradually increased. . Most of the LED scene light dimming systems currently available on the market are illuminated according to a fixed color set in advance, or a color that changes according to a certain rule, and form a set of control equipment. Can not be very humane to achieve scene rendering effect. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies of the prior art, the primary purpose of the present invention is to provide an intelligent dimming metho...
