Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A lamp, a control method thereof, and an apparatus thereof according to an embodiment of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of a lamp according to an embodiment of the present invention. As shown in fig. 1, the method for controlling a lamp according to the embodiment of the present invention includes the following steps:
s101: and controlling the lamp beads in the lamp bead set to be lightened one by one.
According to an embodiment of the present invention, as shown in fig. 2, controlling the lamp beads in the lamp bead set to light up one by one further includes:
s201: and aiming at each lamp bead, obtaining the lighting control signal of the lamp bead.
And if the current brightness of the identified lamp bead reaches the third brightness value, sending a lighting control signal to the next lamp bead.
That is to say, after acquiring the lighting control signal of one lamp bead, the brightness of the lamp bead is changed from the lowest brightness value to the highest brightness value, and in the process of gradual change, when the current brightness reaches the third brightness value, the lighting control signal is triggered to be sent to the next lamp bead in the control logic.
It should be understood that the next bead in the control logic may or may not be a bead adjacent to it in the actual location.
S202: and controlling the lamp bead to circularly change between the first brightness value and the second brightness value according to the lighting control signal.
The first brightness value may be a lowest brightness value of the lamp bead, and the second brightness value may be a highest brightness value of the lamp bead, that is, the lamp bead gradually increases brightness from the lowest brightness value to the highest brightness value after being turned on, and gradually decreases brightness to the lowest brightness value when the brightness reaches the highest brightness value, so as to form a brightness cycle.
Further, controlling the lamp bead to circularly change between the first brightness value and the second brightness value, as shown in fig. 3, further includes:
s301: and acquiring the horse race speed, and calculating a brightness change factor according to the horse race speed.
S302: and superposing the brightness change factor with the current running brightness so as to update the running brightness.
The horse race speed can be the speed of the horse race effect of the lamp, the brightness change factor can be the product of the horse race speed and the change coefficient, when the lamp bead is turned on from off, the change coefficient is an increasing coefficient, when the lamp bead is turned off from on, the change coefficient is a decreasing coefficient, wherein the positive direction and the negative direction can be set when the lamp leaves the factory, the horse race speed can also be set when the lamp leaves the factory, and the horse race speed can also be adjusted and set by a user.
For example, the operation from the first lamp bead to the last lamp bead can be taken as a positive direction, and the operation from the last lamp bead to the first lamp bead can be taken as a negative direction, that is, when the lamp beads operate according to the positive direction, the operation is performed from the first lamp bead until the operation is performed to the last lamp bead; on the contrary, when the lamp beads run in the opposite direction, the operation is started from the last lamp bead until the operation is performed to the first lamp bead.
Specifically, the set horse race speed is obtained, the horse race speed is multiplied by the change factor to obtain a brightness change factor, the current brightness value of the lamp bead is obtained in real time, the current brightness value and the brightness change factor are superposed to obtain the brightness value of the lamp bead at the next moment, and the lamp bead is controlled to be lightened according to the brightness value at the next moment, so that the lamp bead can carry out brightness conversion between the first brightness value and the second brightness value based on the horse race speed.
For example, assume that the first luminance value is 0 and the second luminance value is 255. When a starting instruction for running a horse by a lamp is received, acquiring horse running speed and horse running direction in instruction data, taking the horse running direction as a positive direction as an example, controlling the brightness of a first lamp bead to be a lowest brightness value at a first moment, namely, controlling the brightness value to be 0, at this moment, calculating an incremental factor of the horse running speed and the incremental factor, adding 0 to the calculated incremental factor to obtain a brightness value t2 of the first lamp bead at a second moment, controlling the first lamp bead to be lightened according to t2 at the second moment, then adding t2 to the incremental factor to obtain a brightness value t3 of the first lamp bead at a third moment, controlling the first lamp bead to be lightened according to t3 at the third moment, for example, judging whether t2 is larger than 204 at the moment, if the brightness value is larger than 204, controlling the second lamp bead to be lightened, if the brightness value is larger than 204, judging whether t3 is larger than 204, and so on the like, after the second lamp bead is lighted, the second lamp bead is controlled to start changing the brightness value based on the horse race speed from the first brightness value 0, the process is the same as that of the first lamp bead, and the description is omitted.
When the first lamp bead reaches the second brightness of 255, the process from on to off is started, at this time, the current brightness is 255, the decrement factor is calculated as the horse race speed, and the current brightness is subtracted from the decrement factor obtained by calculation, that is, the current brightness is equal to the current brightness-the decrement factor, until the current brightness is equal to 0. By analogy, when the second lamp bead reaches 255, the brightness of the second lamp bead is controlled to be decreased from 255 to 0. The process is similar to the first lamp bead.
It should be further noted that, in the embodiment of the present invention, a plurality of lamp beads in the lamp bead set may be connected in an end-to-end manner, that is, the first lamp bead may also be a lamp bead next to the last lamp bead, in other words, when the brightness of the last lamp bead reaches 204, the lighting operation of the first lamp bead may be triggered, that is, the first lamp bead stops the brightness cycle of the previous stage of the cycle, and after receiving the lighting control signal sent by the last lamp bead, the conversion between the first brightness value and the second brightness value is executed from the beginning.
S102: when each lamp bead is lightened, the current display color value and the target display color value of the lamp bead are obtained, and the display color value of the lamp bead is adjusted according to the current display color value and the target display color value.
According to an embodiment of the present invention, when each lamp bead is lit, the current display color value and the target display color value of the lamp bead are obtained, and the display color value for lighting the lamp bead is adjusted according to the current display color value and the target display color value, as shown in fig. 4, the method further includes:
s401: the relationship of the current display color value and the target display color value is identified.
S402: and when the current display color value is different from the target display color value, adjusting the current display color value according to the difference value of the current display color value and the target display color value.
Specifically, the transitional display color value is calculated according to the difference value, when the current display color value is smaller than the target display color value, if the transitional display color value is smaller than the target display color value, the current display color value is updated to the target display color value, and if the transitional display color value is larger than or equal to the target display color value, the current display color value is updated to the transitional display color value; and when the current display color value is larger than the target display color value, if the transition display color value is larger than the target display color value, updating the current display color value to the target display color value, and if the transition display color value is smaller than or equal to the target display color value, updating the current display color value to the transition display color value.
It should be noted that, the difference between the current display color value and the target display color value may be a phase difference color value, and the transition display color value may be updated according to the phase difference color value, so that the lamp bead presents the transition display color value in the process of transitioning from the current display color value to the target display color value in the color change process.
Specifically, when the current display color value is different from the target display color value, the relationship between the current display color value and the target display color value is determined:
(1) the current display color value is greater than the target display color value.
At this time, the transition display color value ═ transition display color value — phase difference color value/255 ═ transition display color value | current display color value |/255.
And then, comparing the transition display color value obtained by calculation with the target display color value, and if the transition display color value is smaller than the target display color value, updating the current display color value to the target display color value, namely, directly updating the display color value of the lamp bead to the target display color value.
And if the transitional display color value is larger than or equal to the target display color value, updating the current display color value into a transitional display color value, then obtaining a new transitional display color value according to the updated current display color value and the target display color value, and returning to compare the transitional display color value with the target display color value until the transitional display color value is smaller than or equal to the target display color value, namely, the display color value of the lamp bead is the target display color value.
(2) The current display color value is less than the target display color value.
At this time, the transition display color value + the phase difference color value/255 is the transition display color value + | the current display color value-the target display color value |/255.
And then, comparing the transition display color value obtained by calculation with the target display color value, and if the transition display color value is larger than the target display color value, updating the current display color value to the target display color value, namely, directly updating the display color value of the lamp bead to the target display color value.
And if the transitional display color value is smaller than or equal to the target display color value, updating the current display color value into a transitional display color value, then obtaining a new transitional display color value according to the updated current display color value and the target display color value, and returning to compare the transitional display color value with the target display color value until the transitional display color value is larger than or equal to the target display color value, namely, the display color value of the lamp bead is the target display color value.
Furthermore, after the current display color value of the lamp bead is changed into the target display color value, the lamp bead can be controlled to execute the next target display color value, and therefore circulation is achieved.
It should be noted that, when the current display color value is the same as the target display color value, the control lamp bead is continuously lighted according to the current display color value. The duration may be calculated by the transition display color value, for example, the transition display color value ═ transition display color value + phase difference color value/255, and when the transition display color value reaches 255, the next target display color value is executed. It should be understood that in the process of the present embodiment, the iterative calculation of the transition display color value is only used for the time-delay waiting, i.e., the display color value of the lamp bead is not changed according to the change of the transition display color value.
It should be further noted that, in the embodiment of the present invention, the various color values including, but not limited to, the current display color value, the target display color value, the transition display color value, and the like are RGB values, and when performing the color change, the color update of the R color value may be performed first, then the color update of the G color value is performed, and finally the color update of the B color value is performed until the entire RGB color value is completely updated.
In summary, in the control method of the lamp according to the embodiment of the present invention, the lamp beads in the lamp bead set are controlled to be turned on one by one, so that the lamp bead set is turned on in a linkage manner to form a horse race lamp effect as a whole, and the display color values of the lamp beads are adjusted by the current display color value and the target display color-woven of each lamp bead, so that the color change is provided during the horse race of the lamp bead set.
