Embodiment 1
[0020] figure 1 It shows the lighting adjustment method of the LED lighting device according to Embodiment 1 of the present invention, including the following steps:
[0021] Step S102, receiving a control command from the remote control device, wherein the control command indicates the total brightness to be adjusted by the LED lighting device;
[0022] For example, the control command sent by the remote control device carries the total brightness to which the LED lighting device needs to be adjusted, which is denoted as L'.
[0023] Step S104, respectively multiplying the current brightness ratio of each LED light-emitting tube group by the total brightness to be adjusted by the LED lighting device to obtain the luminous brightness to be adjusted for each LED light-emitting tube group, wherein the brightness ratio refers to the LED light-emitting The ratio of the luminance of the tube group to the total luminance of the LED lighting device;
[0024] The display of the colo...
Embodiment 2
[0031] In Embodiment 1, if the LED lighting device contains three LED light-emitting tube groups, which are red, green, and blue LED light-emitting tube groups, the red, green, and blue LED light-emitting tube groups can be calculated according to formula (1). The luminous brightness B' to be adjusted to by each luminous tube group red , B' green and B' blue :
[0032] B red ′ = C red × L ′ B green ′ = C green × L ...
Embodiment 3
[0036] In Embodiment 1, if the LED lighting device includes two groups of white LED light-emitting tubes with different color temperatures, namely the first group of white LED light-emitting tubes and the second group of white LED light-emitting tubes, then formula (1) can be used to calculate Obtain the luminous brightness B' to be adjusted to by the first white LED light-emitting tube group and the second white LED light-emitting tube group respectively 1 , B' 2 :
[0037] B 1 ′ = C 1 × L ′ B 2 ′ = C ...

Abstract
The invention discloses a light-emitting diode (LED) illuminating device and a light regulation method thereof. The LED illuminating device comprises at least two LED luminotron sets inside. The light regulation method comprises the following steps of: receiving a control command sent by a remote control device, wherein the control command indicates total brightness to which the LED illuminating device needs to be adjusted; respectively multiplying current brightness ratios of all the LED luminotron sets and the total brightness to which the LED illuminating device needs to be adjusted to obtain brightness to which every LED luminotron set needs to be adjusted, wherein the brightness ratio refers to a specific value of the brightness of the LED luminotron sets to the total brightness of the LED illuminating device; and respectively regulating all the LED luminotron sets to the corresponding brightness to which the LED luminotron sets need to be adjusted. According to the LED illuminating device and the light regulation method thereof disclosed by the invention, an effect that colors cannot be influenced when the brightness of the LED illuminating device is adjusted is achieved, and the problem that the colors can be changed when the brightness of the LED illuminating device is adjusted in the prior art is solved.
Description
technical field [0001] The present invention relates to the technical field of lighting, and more specifically, to an LED lighting device and a lighting adjustment method thereof. Background technique [0002] In recent years, with the promotion of energy-saving technology, energy-saving lighting design has become the focus of research in the field of lighting fixtures. LED (Light Emitting Diode, Light Emitting Diode) has the advantages of high luminous efficiency, good energy-saving effect, etc., and has received people's attention in energy-saving lighting design. Using LEDs as lighting devices to replace traditional lighting devices is a development trend in today's lighting technology field. [0003] In order to meet the different preferences of different users in terms of brightness and color, LED lighting devices capable of adjusting brightness and color have also come out one after another. At present, the commonly used LED lighting devices with adjustable brightnes...
