Referring to the drawings, fig. 1 is a schematic flow chart of a light control method of a balance induction lamp according to an embodiment of the present invention, which specifically includes: steps S101 to S104.
S101, acquiring an original brightness value and an input target brightness value of each light bar in a balanced induction lamp, and acquiring an original angle value and an input target angle value of the balanced induction lamp;
s102, comparing the original brightness value of each light bar with a preset target brightness value, and comparing the original angle value with the target angle value to obtain a comparison result;
s103, acquiring a brightness interval to which the original brightness value of each light bar belongs;
and S104, controlling the light change of each light bar according to a preset strategy based on the comparison result and the brightness interval of each light bar.
According to the embodiment of the invention, the reference information of the light change can be obtained by comparing the original brightness value and the target brightness value of each light bar and the original angle value and the target angle value of the balance induction lamp, and the light change of the light bars is controlled according to the preset strategy corresponding to the brightness interval by combining the brightness interval corresponding to each light bar, so that the effect of carrying out linkage control on the light bars according to the gyroscope parameters is achieved, and the light change of the balance induction lamp has a streamline visual effect.
In one embodiment, the light bars comprise two light bars with different colors, the two light bars with different colors are respectively connected with a control chip, the balance induction lamp further comprises a touch key and a gyroscope, the touch key and the gyroscope are respectively connected with the control chip, and the light bars with two different colors are controlled by the touch key to input corresponding original brightness values and target brightness values;
the original angle value and the target angle value of the balance induction lamp are controlled and input by a gyroscope, and the gyroscope supports multi-stage light change of each preset angle.
Furthermore, the control chip comprises a main chip and an auxiliary chip, the main chip is respectively connected with the lamp strip and the touch key of one color, and the auxiliary chip is respectively connected with the lamp strip and the gyroscope of another color.
In this embodiment, two different color light bars are adopted, that is, as shown in fig. 4, the two color light bars are respectively a white LED lamp and a yellow LED lamp, wherein the white LED lamp is connected to a main chip, the main chip is controlled by a touch key through a TTL level signal (i.e., a transistor-transistor level signal), the yellow LED lamp is connected to a sub-chip, the sub-chip is controlled by a gyroscope through an i2c bus (a bidirectional two-wire system synchronous serial bus), and meanwhile, the main chip is communicated with the sub-chip through a uart bus (a universal asynchronous transceiver transmitter). The embodiment controls the light change through the double chips, and avoids the problem of higher cost caused by adopting the chip with stronger performance.
In a specific embodiment, the preset angle is 30 degrees, that is, the embodiment of the invention supports the light change of the gyroscope every 30 degrees, and improves the brightness change algorithm of the light, so that the desk lamp has a streamline visual effect on the user vision when the desk lamp is changed.
Further, in conjunction with fig. 5, there are four input parameters in this embodiment, which are an original brightness value a and a target brightness value b controlled by the touch key, and an original angle value c and a target angle value d at which the balance induction lamp is located and input by the gyroscope. Comparing the original brightness value a with the target brightness value b, and comparing the original angle value c with the target angle value d, so as to obtain four different comparison results, and for the four different comparison results, different lighting control algorithms, that is, lighting control algorithm 1, lighting control algorithm 2, lighting control algorithm 3, and lighting control algorithm 4 in fig. 5, may be correspondingly adopted in this embodiment. It will of course be appreciated that although the four light control algorithms are different, the principle of the four light control algorithms is essentially the same, i.e. only differ by increasing or decreasing the brightness value, or by increasing or decreasing the angle value.
In one embodiment, the step S104 includes:
and based on the comparison result and the brightness interval to which each light bar belongs, controlling the light brightness of one color light bar to increase according to a preset strategy, and controlling the light brightness of the other color light bar to decrease according to the preset strategy.
In this embodiment, the light of the lamp strip of two kinds of different colours is effectual synchronous through the asynchronous light transform of many lamp strips, and the lamp strip of two kinds of colours adopts the same strategy of predetermineeing to carry out light control promptly, but the light luminance of the lamp strip of a colour is for increasing, and the light luminance of the lamp strip of another kind of colour is for descending. Therefore, the brightness of the light can be dynamically and uniformly increased or decreased, the change of the light is more unobtrusive due to the asynchronous conversion of the multiple light bars, and the use feeling of a user is better.
In an embodiment, as shown in fig. 2, the light control method of the balance induction lamp further includes: steps S201 to S202.
S201, setting a light pulse width modulation upper limit value of the obtained balance induction lamp;
s202, uniformly dividing the lamp brightness of the balance induction lamp into a plurality of brightness intervals based on the pulse width modulation upper limit value;
s203, setting the preset strategy corresponding to each brightness interval to change the brightness of the lamplight according to different times of speed.
In this embodiment, according to the light pulse width modulation upper limit value of balanced induction lamp, evenly divide into a plurality of luminance intervals with the light luminance of lamp strip to set up corresponding speed of multiplying for each luminance interval and change light luminance, even the policy diverse is predetermine to each luminance interval correspondence. For example, the upper limit of the light pulse width modulation is set to be a multiple of 6, so that the brightness interval can be uniformly divided into 6 brightness intervals; for another example, if the upper limit of the lamp pulse width modulation is set to be a multiple of 8, the luminance interval can be uniformly divided into 8 luminance intervals.
In a specific embodiment, the number of the brightness intervals is 6, and the brightness intervals are marked as x1, x2, x3, x4, x5 and x6 in sequence according to the height; the preset strategy corresponding to each brightness interval is set to change the brightness of the lamplight according to different multiple speeds, and the method comprises the following steps:
setting x3 and x4 as a third brightness interval, and setting a preset strategy corresponding to the third brightness interval to change the brightness of the lamp light at a double speed;
setting x2 and x5 as a second brightness interval, and setting a preset strategy corresponding to the second brightness interval to change the brightness of the lamp light at twice speed;
setting x1 and x6 as a first brightness interval, and setting a preset strategy corresponding to the first brightness interval to change the brightness of the lamp light at a triple speed.
In real life, human eyes are not very sensitive to a lower area and a higher area of pwm (pulse width modulation) brightness values, so the embodiment divides the lamp brightness into 6 brightness intervals, and takes the x1 and x6 intervals as a first brightness interval, and sets a corresponding preset strategy to change the brightness at a triple speed; taking the x2 and x5 intervals as a second brightness interval, and setting the corresponding preset strategy to change the brightness at double speed; and taking the x3 and x4 intervals as second brightness intervals, and setting the corresponding preset strategy to change the brightness at a double speed, so that the uniform change of the brightness of the light in human eyes can be better realized.
In addition, the amplitude of the light change is different due to the different angles of the rotating gyroscope of the user, and when the light is changed at a fixed rate, the light changes at a slow speed. Therefore, in this embodiment, the time of the lamp change caused by different input parameters is substantially the same under the condition of local uniformity as much as possible, for example, the time T of each lamp change is set to 2000 cycles.
In one embodiment, as shown in fig. 3, the step S104 includes: steps S301 to S306.
S301, obtaining the change magnification of the lamplight; wherein the change multiplying power is an increase multiplying power or a decrease multiplying power;
s302, controlling light change according to change multiplying power corresponding to multiplying speed based on a brightness interval to which a light bar belongs, and recording the periodicity of the light change;
s303, judging whether the changed brightness value of the light bar meets a preset requirement or not by combining the target brightness value;
s304, when the brightness value of the changed light bar meets the preset brightness requirement, starting to control the light change of the next light bar.
In this embodiment, referring to fig. 6, y in fig. 6 represents a current luminance value of the light bar, and the current luminance value y is equal to the original luminance value a, that is, the light change is performed based on the original luminance value of the light bar. When the light is controlled to change, firstly, the change magnification of the obtained light needs to be calculated, and it is understood that the change magnification here may refer to an increase magnification (such as an increase rate in fig. 6) or a decrease magnification, and is specifically determined by the original luminance value and the target luminance value of the light bar, that is, when the original luminance value is less than or equal to the target luminance value (such as y < ═ b in fig. 6), the change magnification is the increase magnification, and when the original luminance value is greater than the target luminance value, the change magnification is the decrease magnification.
Then, the brightness interval of the light bar is judged, and then the light change according to which multiple speed can be determined. Specifically, when the brightness interval of the light bar is a first brightness interval, the light is changed according to the change multiplying power of 3 times speed; when the brightness interval of the light bar is a second brightness interval, light change is carried out according to the change multiplying power of 2 times of speed; and when the brightness interval of the light bar is a third brightness interval, the light is changed according to the change multiplying power of 1 time speed. As shown in fig. 6, after the light change is completed, the current luminance value of the light bar is increased to y +3k, or y +2k, or y + k.
Meanwhile, when the light bar is controlled to change the light, the number of cycles of the light change is recorded, for example, the number of cycles of the light change is added to 1, so that the number of cycles required in the process of enabling the overall light change to reach the target value is basically consistent. The situation that the time length of the whole light change is different due to the fact that the user rotates the gyroscope in angle or the brightness is adjusted in different sizes is avoided, and therefore poor experience is brought to the user.
In one embodiment, the preset brightness requirement is: (b-a)/3+ a, wherein a is an original brightness value and b is a target brightness value.
As shown in fig. 7, in the present embodiment, an asynchronous control method of multiple light bars is adopted, and when the brightness of the current light bar Ln meets the preset brightness requirement, that is, Ln > ═ b-a)/3+ a, the brightness control of the next light bar L (n +1) is started, and so on, until the light change of all light bars is completed. In the embodiment, it is considered that the brightness change of the single light bar one by one is more abrupt in visual effect, and the change time is slower, and if the asynchronous brightness change is performed by adopting a plurality of light bars, the change process is smoother, so that the visual effect of the light change is better.
In an embodiment, the obtaining of the variation magnification of the light includes:
calculating the change multiplying factor k of the lamplight according to the following formula:
k＝rw/n(T-e)
in the formula, r is the number of cycles when k is 1, w is the number of light bars required to be changed, n represents n light bars, T is the expected total cycle, and e is the number of additional cycles spent when the number of light bars is not changed simultaneously when the light change starts and ends.
In this embodiment, when the change magnification of the light is calculated, the change magnification of the light is set to 1, so that the number r of cycles that the light changes can be obtained, and then the number of light bars that need to be changed can be determined according to the original angle value and the target angle value of the balance induction lamp, that is, according to a formula w ═ d-c)/30, where d and c are the target angle value and the original angle value, and 30 is a preset unit rotation angle of the gyroscope. And then, calculating the expected total period of the light change, wherein the calculation formula is T ═ sw/n + e, and s is the period number required by the actual light change of the single light bar. The change magnification of the lamp light can be changed according to the formula T ═ r/s, wherein s can be obtained by converting the formula T ═ sw/n + e, so that the change magnification can be obtained by calculating the formula of the change magnification of the lamp light through the formula, and the effect of enabling the brightness of the lamp light and the time to be uniformly changed under the condition that different target brightness values and target angle values are input can be realized.
As shown in fig. 8, when the light of the balance induction lamp is controlled to change, the input change of the light bar of the balance induction lamp, that is, the original brightness value and the target brightness value of the light bar, and the original angle value and the target angle value of the balance induction lamp, are detected first, and then the algorithm corresponding to the light bar is determined according to the changes of the four parameters, that is, the preset strategy corresponding to the light bar is determined. And calculating the k value of the light bar, namely the change multiplying power, then carrying out light change control on the light bar according to a single light bar algorithm, and recording the number of cycles of light change. According to the steps, light change control is carried out on two different color light bars of the balance induction lamp, namely, the light change is controlled by adopting a multi-light-bar synchronous algorithm.
