Example 1
As shown in fig. 1, fig. 1 is a flowchart of a lighting device control method according to a first embodiment of the present invention, including:
step S101: receiving a control instruction for controlling the color of the lighting device to be controlled;
step S102: acquiring a first RGB value of a first color, a second RGB value of a second color, a functional period T1 and response time T2 of a lighting device to be controlled according to a control instruction;

Specifically, when the lighting device needs to be controlled, such as a guest-welcome mode triggered when the door is opened, a control instruction for controlling the color of the lighting device to be controlled is input by a user, firstly, the controller executes step S101 to receive the control instruction input by the user; secondly, the controller executes step S102 to obtain a first RGB value of a first color, a second RGB value of a second color, a functional period T1 and a response time T2 of the lighting device to be controlled according to the control instruction, taking the current color breathing, the breathing process being that the lighting is changed from bright to dark, as an example, the current color of the lighting device to be controlled is taken as the first color, the RGB value corresponding to the current color is taken as the first RGB value, the RGB value corresponding to the current color is extinguished as the second color, the RGB value corresponding to the second color is taken as the second RGB value, the color of the lighting device to be controlled and the corresponding RGB value can be stored in the system in advance, the types of the colors can be set according to the requirements, for example, the colors can be the conventional red, orange, yellow, green, cyan, blue and purple seven colors, or the current popular 64 colors, because the colors can be directly extracted through the setting interface, the change of the corresponding color setting can be achieved without inquiring the color index table; then, the controller executes step S103 to obtain a timing parameter k corresponding to each moment in a preset period, and calculates a current moment RGB value corresponding to each moment according to the timing parameter k, the first RGB value, the second RGB value, the functional period T1 and the response time T2, where the timing parameter k can clock the output color according to the response time T2 by a timer, for example, when the response time T2 is 0.1S, the timer counts once every 0.1S, and the timing parameter k is increased by 0.1S, so that the current moment RGB value changes along with the change of the timing parameter k, thereby obtaining RGB values of all colors; finally, the controller performs step S104 to control the color change of the lighting device to be controlled by using the RGB value at the current time.
The color control method of the lighting device to be controlled is the same as the existing color control method of the LED lamp, and is not described herein.
The response time refers to a time interval of color change of the lamp to be controlled, for example, when the control time interval is 0.1s, the color is displayed every 0.1 s. The functional period T1 refers to the time required for the light color to be changed from the first color to the second color and back to the first color in equal proportion according to a specified control rule, for example, the time required for the welcome mode to be red-black-red when the vehicle door is opened is 4s, and the functional period T1 is 4s.
Wherein the controller is preferably an electronic control unit (Electronic Control Unit, ECU).
According to the lighting device control method, when the control instruction for controlling the colors of the lighting device to be controlled is received, the first RGB value of the first color, the second RGB value of the second color, the functional period T1 and the response time T2 of the lighting device to be controlled are obtained according to the control instruction, the timing parameter k corresponding to each moment is obtained in the preset period, the current moment RGB value corresponding to each moment is calculated according to the timing parameter k, the first RGB value, the second RGB value, the functional period T1 and the response time T2, and the lighting device to be controlled is controlled according to the current moment RGB value, so that breathing control of all color atmosphere lamps is achieved, a color index table does not need to be stored in advance, when breathing control of more color atmosphere lamps is needed, only new colors and corresponding RGB values need to be added in a system, the development period is short, the requirement of rapid iteration can be met, and the expansibility is good.
Example two
As shown in fig. 2, fig. 2 is a flowchart of a lighting device control method according to a second embodiment of the present invention, including:
Step S201: receiving a control instruction for controlling the color of the lighting device to be controlled;
Step S202: acquiring a first RGB value of a first color, a second RGB value of a second color, a functional period T1 and response time T2 of a lighting device to be controlled according to a control instruction;
Step S203: in a preset period, obtaining a timing parameter k corresponding to each moment, and calculating a current moment RGB value corresponding to each moment according to the timing parameter k, the first RGB value, the second RGB value, the functional period T1 and the response time T2;
step S204: updating a timing parameter k when calculating the RGB value of the current moment once;
step S205: judging whether the timing parameter k is within a preset period;
step S206: stopping calculating the RGB value at the current moment;
step S207: judging the position of the timing parameter k in the functional period T1 at the previous moment when the timing parameter k exceeds the preset period;
Step S208: if the timing parameter k is in the first sub-period of the functional period T1, controlling the lighting device by using the first RGB value;
step S209: if the timing parameter k is in the second sub-period of the functional period T1, controlling the lighting device by using a second RGB value;
step S210: judging whether the difference value between the timing parameter K value and the timing parameter K' at the end of the first sub-period is within a preset difference value threshold;
step S211: controlling the lighting device according to the second RGB value;
Step S212: the lighting device is controlled according to the first RGB value.
Specifically, when it is necessary to control the lighting device, first, the controller executes step 201 to receive a control instruction.
Next, the controller executes step S202 to obtain a first RGB value of a first color, a second RGB value of a second color, a functional period T1 and a response time T2 of the lighting device to be controlled;

Then, the controller performs step S204 to update the timing parameter k each time the current time RGB value is calculated;
finally, the controller executes step S205 to determine whether the timing parameter k is within the preset period, if yes, executes step S204, otherwise executes steps S206-S207 to stop calculating the RGB value at the current time, and determines the position of the timing parameter k in the functional period T1 at the previous time beyond the preset period, if the timing parameter k is in the first sub-period of the functional period T1, executes step S208 to control the lighting device with the first RGB value, and if the timing parameter k is in the second sub-period of the functional period T1, executes step S208 to control the lighting device with the second RGB value.
Meanwhile, the controller executes step S210 to determine whether the difference between the timing parameter K value and the timing parameter K' at the end of the first sub-period is within the preset difference threshold, if yes, step S211 is executed, otherwise step S212 is executed.
The functional period T1 includes a first sub-period and a second sub-period, where the first color and the second color controlled by the first sub-period are opposite to the first color and the second color controlled by the second sub-period, for example, when the color controlled by the first sub-period is red-black, the color controlled by the second sub-period is black-red, and the first sub-period and the second sub-period form a complete functional period T1, and when an atmosphere effect of multiple functional periods is needed, only the atmosphere effect of one functional period is needed to be executed in a circulating manner, so that occupied memory is further reduced, and operation efficiency is improved. The preset difference threshold is the number of response times T2 in a complete functional period T1. Preferably, the preset difference threshold is + -T1/4T 2.
According to the lighting device control method, when the control instruction for controlling the colors of the lighting device to be controlled is received, the first RGB value of the first color, the second RGB value of the second color, the functional period T1 and the response time T2 of the lighting device to be controlled are obtained according to the control instruction, the timing parameter k corresponding to each moment is obtained in the preset period, the current moment RGB value corresponding to each moment is calculated according to the timing parameter k, the first RGB value, the second RGB value, the functional period T1 and the response time T2, and the lighting device to be controlled is controlled according to the current moment RGB value, so that breathing control of all color atmosphere lamps is achieved, a color index table does not need to be stored in advance, when breathing control of more color atmosphere lamps is needed, only new colors and corresponding RGB values need to be added in a system, the development period is short, the requirement of rapid iteration can be met, and the expansibility is good.
In one embodiment, to adapt to the linear variation law, when the control law is a linear function, in the first sub-period, the current time RGB value is calculated by the following equation (1):

preferably, in order to adapt to the nonlinear variation law, when the control law is a quadratic function, the current time RGB value is calculated by using the following expression (4) instead of the expression (2):
In one embodiment, in order to improve the operation efficiency, the calculating the current time RGB value by using the first RGB value, the second RGB value, the functional period T1 and the response time T2 further includes:
and performing floating point number removal processing on the RGB value at the current moment.
In one embodiment, the removing floating point number processing on the current time RGB value specifically includes:
The current time RGB values are processed using integer four operations.
Specifically, in the first sub-period, the above equation (1) is multiplied by an integer variable which can make the operation result an integer at the same time on both sides, and preferably, in order to improve the operation efficiency, the integer variable is cT 1, where c is a constant which is multiplied by the control frequency to an integer, and therefore, the above equation (1) is converted into the following equation (5):
Similarly, in the second sub-period, the two sides of the formula (2) are multiplied by an integer variable which can make the operation result an integer, preferably, in order to improve the operation efficiency, the integer variable is cT 1, where c is a constant which is multiplied by the control frequency to an integer, and therefore, the formula (2) is converted into the following formula (6):
As can be seen from the above equations (5) and (6), the RGB output values obtained by processing the RGB output values by the integer four-way operation are all integer values, and floating point numbers are eliminated, so that the operation process does not include floating point operation, the operation efficiency is improved, and the method is suitable for a common controller and improves universality.
Similarly, when the control rule is a quadratic function, the floating point number removal process may be performed on the above formulas (3) and (4) by the same method, and will not be described here again.
