The power proportion that two kinds of lamp pearls mix is different, alright in order to form different colour temperatures. For example, a 100W lamp with two color temperatures, wherein the cold color temperature lamp bead with 2700K has a power of 95W, and the warm color temperature lamp bead with 6500K has a power of 5W, the color temperature of the light emitted by the two color lamp is the cold color temperature, for example, about 3000K.
In practical applications, a flashing situation sometimes occurs during the power-on phase of the two-color lamp. This is particularly the case when starting up at a lower color temperature or at a higher color temperature, for example at a lower color temperature of 3000K or at a higher color temperature of 5500K. In addition, this is also the case for lamps that have 3 or more than 3 beads of different color temperatures built in, in addition to the two-color lamp. Such a situation may degrade the quality of the product, for example a user finds it, and the quality of the bi-color lamp in which it occurs is considered to be defective.
In summary, how to avoid the flashing of the multi-color lamp when the lamp is powered on is a technical problem that needs to be solved urgently by those skilled in the art.

Detailed Description
The core of the invention is to provide a control method of the multicolor lamp, which can avoid the flash condition when the multicolor lamp is electrified.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of an implementation of a method for controlling a multi-color lamp according to the present invention, in the multi-color lamp, there are N kinds of lamp beads with different color temperatures, each lamp bead has a corresponding driving circuit, and N is a positive integer not less than 2.
The applicant finds that the flashing of the multi-color lamp occurs during the power-on process because each lamp bead has a corresponding control signal, and the duty ratio of the control signal gradually increases from 0, usually linearly, and finally reaches the target value corresponding to the control signal. The target values corresponding to different control signals are different, and the change rate of the duty ratio is different. For example, fig. 2 shows a change condition of a control signal in a power-on process of a dual-color lamp in a specific case of a conventional scheme, PWM _ C in fig. 2 shows a change condition of a control signal corresponding to a warm-color-temperature lamp bead in a starting process, and PWM _ W shows a change condition of a control signal corresponding to a cold-color-temperature lamp bead in a starting process, which shows that a duty ratio change rate of a control signal corresponding to a warm-color-temperature lamp bead is much higher than a duty ratio change rate of a control signal corresponding to a cold-color-temperature lamp bead.
Also, when a multi-colored lamp is started with a lower color temperature or with a higher color temperature, the difference in the rate of change of the duty cycles of the different control signals is greater. And various lamp pearls have respective drive circuit, and the rate of change of duty cycle is different, can lead to the electric capacity among the different drive circuit to charge consuming time different. The control signal with the faster duty ratio rises, the shorter the charging time of the capacitor in the corresponding driving circuit is, and therefore the lamp bead connected with the driving circuit is lightened earlier. After a certain lamp bead is lighted, a lamp bead is lighted at intervals, and the condition of flashing the lamp can be generated. Fig. 3 shows a schematic circuit structure diagram of a driving circuit of a common two-color lamp, when duty ratios of respective control signals of two driving circuits are shown in fig. 2, a capacitor CE2 in fig. 3 is fully charged earlier than a capacitor CE4, after the capacitor CE2 is fully charged, a warm-color warm-light bulb is first lit, and then a cold-color warm-light bulb is lit, so that a situation that a human eye visually flashes the lamp occurs.
The control method of the multi-color lamp of the application can comprise the following steps:
step S101: and receiving a light-on instruction.
The controller can receive the light-on instruction, and the light-on instruction can be input by a user, for example, the user inputs the light-on instruction to the controller through an input device such as a key and the like, or the light-on instruction is automatically triggered by a related process, so that the implementation of the invention is not influenced.
Step S102: outputting a control signal to each driving circuit of the multicolor lamp so as to control the lamp beads of various color temperatures in the multicolor lamp to be simultaneously lightened through each driving circuit in a first period;
the first time interval is a time interval from the moment of receiving the lighting instruction to a first moment after a preset first time length, and for any moment in the first time interval, the duty ratios of the control signals corresponding to the various lamp beads at the moment are the same.
After receiving the lighting instruction, the controller can output a control signal to each driving circuit of the multi-color lamp. And aiming at any time in the first period, the duty ratios of the control signals corresponding to the various lamp beads at the time are the same. It should be noted that the number of the lamp beads in each driving circuit may be one or more, but the color temperatures of the lamp beads sharing one driving circuit are the same, and the lamp beads may be connected in series or in parallel.
Fig. 4 is a schematic diagram showing variations of control signals in a specific case of the present invention, and in fig. 4, the controller outputs control signals having the same duty ratio to each of the driving circuits of the multi-color lamp in a period of 500ms during which the controller receives a lighting command.
The specific value of the first duration can be set and adjusted according to actual needs, but it should be noted that, because in the scheme of the application, the lamp beads of various color temperatures in the multicolor lamp need to be controlled to be simultaneously lightened in the first period, the first period cannot be set too short, that is, the situation that various lamp beads in the multicolor lamp are not lightened after the first period elapses cannot occur. In practical application, the capacitance value of the relevant capacitor in the circuit can be generally analyzed, the lamp bead model and other parameters are determined for the first time length, and certainly, the value of the appropriate first time length can be determined through experiment verification.
Because the duty ratios of the control signals corresponding to the various lamp beads at any moment in the first period are the same, the charging speeds of the capacitors in the driving circuits of the various lamp beads are the same, and the various lamp beads can be simultaneously lightened. It should also be emphasized that, the first time duration is set in the present application, and the various lamp beads may be turned on at the same time just after the first time duration elapses, that is, the various lamp beads are turned on at the same time just after the first time duration ends, or the various lamp beads are turned on at the same time during the first time duration, which does not affect the implementation of the present invention.
Step S103: after the first period, the duty ratios of the control signals are respectively adjusted to corresponding target values according to a preset control strategy, so that the lamp beads with various color temperatures reach respective working states.
Because the duty ratio of the control signal corresponding to each lamp bead at any moment in the first period is the same, the lamp beads can be simultaneously lightened. However, after the first period of time is over, the various lamp beads may not reach the working state, that is, the duty ratio of the control signal of each lamp bead needs to be continuously adjusted until reaching the respective target value, so that the lamp beads of various color temperatures enter the respective working states.
For example, in fig. 4, after a first period of time, the duty ratios of the control signals corresponding to the cold color temperature lamp beads and the control signals corresponding to the warm color temperature lamp beads are both adjusted to 10%, then the duty ratio of the control signals corresponding to the warm color temperature lamp beads is adjusted to 55%, and the duty ratio of the control signals corresponding to the cold color temperature lamp beads is adjusted to 18%. Of course, in other practical situations, the target values of the control signals corresponding to the various lamp beads may have other values.
The control signal described in this application may be a PWM (Pulse width modulation) control signal, which is a widely used and easily implemented control signal form.
By applying the technical scheme provided by the embodiment of the invention, after the light-on command is received, the control signal is output to each driving circuit of the multicolor lamp. The first time period refers to a time period from the moment of receiving the lighting instruction to a first moment after a preset first time length, and at any moment in the first time period, the duty ratios of the control signals corresponding to the various lamp beads are the same, so that the lamp beads of various color temperatures in the multicolor lamp can be controlled to be simultaneously lighted through the driving circuits in the first time period. After the first period, the duty ratios of the control signals are respectively adjusted to the corresponding target values according to a preset control strategy, so that the lamp beads with various color temperatures can all reach respective working states. It can be seen that because the lamp pearl of various colour temperatures in this application scheme is lighted simultaneously, consequently can avoid the flashing light condition when polygenetic lamp is electrified.
In a specific embodiment of the present invention, the value of N is 2, and the multicolor lamp is a bicolor lamp having at least one cold color temperature lamp bead and at least one warm color temperature lamp bead. In the embodiment of fig. 4, N-2 is also taken as an example for explanation, and in other cases, N may have other values, but it should be noted that in practical application, a widely applied scheme is still a two-color lamp with N-2.
In a specific embodiment of the present invention, the step S102 of outputting a control signal to each driving circuit of the multi-color lamp may specifically be:
aiming at a lamp bead with any color temperature in a multicolor lamp, from the moment of receiving a lamp-on instruction to the first moment, a PWM control signal with the duty ratio linearly increased from 0 is output to a driving circuit corresponding to the lamp bead.
For each color temperature lamp bead, in a first period, the duty ratio of the control signal corresponding to the lamp bead is gradually increased, and the change trend of the duty ratio of the control signal of each lamp bead is the same. When the duty ratio of the control signal is increased, the duty ratio may be increased linearly or nonlinearly. The implementation mode selects a scheme of linear improvement, is convenient to implement, and has simple related program setting. In the embodiment of fig. 4, the variation of the duty cycle of the control signal during the first period is also the scheme chosen, i.e. the linearity is increased.
In an embodiment of the present invention, step S103 may specifically be:
after the first period, aiming at the lamp bead with any color temperature in the multicolor lamps, the control signal corresponding to the lamp bead is linearly increased to the target value corresponding to the lamp bead.
For example, in the embodiment of fig. 4, after the first period, the duty ratio of the control signal is linearly increased for each lamp bead until the duty ratio is increased to the respective target value. Of course, the speed of the rise of the duty cycle of different control signals may be different. The hoisting speed may generally be preset, and the higher the target value, the higher the hoisting speed may generally be preset. The implementation mode of linear lifting is adopted, and convenience is brought to implementation of the application. However, it should be noted that, in some cases, the boosting may also be performed non-linearly, for example, for a lamp bead with a higher target value, after the first period, the duty ratio of the control signal corresponding to the lamp bead may be first boosted at a higher rate, and then the boosting rate may be gradually decreased.
In a specific embodiment of the present invention, the lighting instruction is a lighting instruction carrying target values corresponding to lamp beads of various color temperatures.
In some cases, the target value may be preset in the controller, but such a manner is not convenient for adjusting the integrated color temperature of the multicolor lamp at any time, and in this embodiment, the lighting instruction is a lighting instruction carrying respective target values corresponding to the lamp beads of various color temperatures, which is beneficial for conveniently adjusting the color temperature of the multicolor lamp, that is, the target values corresponding to the various lamp beads in the lighting instruction are adjusted and then input to the controller to achieve adjustment.
In an embodiment of the present invention, after step S101, the method may further include:
judging whether the difference value between the maximum value and the minimum value in the target value carried by the lighting instruction exceeds a preset range or not;
if yes, outputting a control signal to each driving circuit of the multicolor lamp so as to control the lamp beads of various color temperatures in the multicolor lamp to be simultaneously lightened by each driving circuit in a first period;
if not, respectively adjusting the duty ratio of each control signal to the corresponding target value according to a preset control strategy so as to enable the lamp beads of various color temperatures to reach respective working states.
In this kind of embodiment, consider among the traditional scheme, because the electric capacity among the different drive circuit charges consuming time difference and leads to the bright lamp of different lamp pearls asynchronous, the condition of flashing lamp appears, consequently the various lamp pearls of scheme control of this application are lighted simultaneously and are avoided the flashing lamp. Furthermore, in some occasions of considering the traditional scheme, although the lighting of different lamp beads is asynchronous, if the interval is short, the naked eyes cannot detect obvious abnormity. Therefore, when the difference value between the maximum value and the minimum value in the target value carried by the lighting instruction is judged not to exceed the preset range, the controller can still light according to the original scheme, namely after the lighting instruction is received, according to the preset control strategy, the duty ratio of the control signal corresponding to the lamp bead with the higher target value is promoted according to the higher change rate, and the duty ratio of the control signal corresponding to the lamp bead with the lower target value is promoted according to the lower change rate, so that the lighting process of the multicolor lamp is accelerated, and the lighting time is saved. Of course, if it is determined that the difference between the maximum value and the minimum value in the target value carried by the lighting instruction exceeds the preset range, it indicates that if the lighting is not synchronized, the interval is long, and a flashing situation is caused, so the operation of step S102 needs to be performed.
