Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
In combination with the background art, in the dimming method in the prior art, because the light is usually adjusted at a constant adjustment rate, a user can easily perceive the turning on or off of the dimming of the lamp when switching between different scenes, so that the user can feel frustrated visually, and the user experience is poor.
Exemplarily, as shown in fig. 1, it is a trend graph of the brightness of the lamp in the dimming process as a function of the adjusting time in the prior art. Wherein, the vertical axis represents the brightness value L of the lamp, the horizontal axis represents the adjusting time T, T represents the adjusting time length, Δ T represents a stepping time interval, Δ L represents the brightness change value corresponding to the stepping time interval, and LfRepresenting the luminance target value. As can be seen from the figure 1 of the drawings,in the dimming process in the prior art, the brightness value of the lamp linearly increases within the adjusting time length T and increases from an initial value 0 to a target brightness value Lf. In the whole dimming process, the adjustment rate is a constant, that is, the brightness change value Δ L corresponding to each step time interval Δ T is equal in the adjustment duration T. This may cause the user to visually predict that the next step time interval Δ T will generate the brightness change of the corresponding brightness change value Δ L due to the existence of Visual Inertia (VI) after the adjustment time period T is reached. However, in practice, when the adjustment time period T is reached, the brightness value of the lamp has changed to the target brightness value LfIn the next step time interval Δ t, the brightness value of the lamp will not change any more, and at this time, the user will feel frustrated visually, even feel uncomfortable, resulting in poor user experience.
In addition, in some scene change processes, in order to make the light change smoothly, a lower adjusting rate is generally adopted in the prior art, but the adjusting time of the lamp is increased. When dimming of each lamp in a lamp group in the same scene is performed, due to the fact that the initial states of different lamps are different and the adjusting time durations of the different lamps are different, the ending time of the dimming process is different, and therefore the lamp light of a user does not change synchronously in vision, and the user feels uncomfortable.
Aiming at overcoming at least one of the defects, the embodiment of the disclosure provides a dimming method, a device, a medium, a lamp and a lamp set with variable adjusting rate. The dimming method comprises the steps of obtaining an initial value, a target value and an adjusting time length of a dimming process; determining an adjustment stage based on the adjustment duration; the adjusting stage comprises a first stage and a second stage, wherein the first stage is prior to the second stage, the adjusting rate is increased in the first stage, and the adjusting rate is decreased in the second stage; determining the adjusting rate of each adjusting stage based on the initial value, the target value and the adjusting stage; wherein, the initial adjusting rate of the first stage and the ending adjusting rate of the second stage are both smaller than the preset rate threshold. Therefore, the adjusting stage can be determined based on the obtained adjusting duration, the adjusting stage comprises a first stage of increasing the adjusting rate and a second stage of decreasing the adjusting rate, and the first stage is prior to the second stage, so that in the dimming process of the lamp, the adjusting rate is wholly in a changing trend of increasing firstly and then decreasing, because the initial adjusting rate of the first stage and the termination adjusting rate of the second stage are both smaller than a preset rate threshold value, the light variation quantity at the beginning and the end of the dimming process is smaller, the slow start (including slow light) and slow stop (including slow light) of the dimming process are realized, the beginning and the end of the dimming process are easier to accept visually by a user, the visual frustration of the user in the dimming process is further improved, and the use experience of the user is improved.
The following describes exemplary dimming methods, apparatuses, mediums, luminaires and luminaire groups for luminaires according to embodiments of the present disclosure with reference to fig. 2 to 12.
In an embodiment, as shown in fig. 2, a flowchart of a dimming method of a lamp according to an embodiment of the present disclosure is shown. Referring to fig. 2, the method may include the steps of:
s101: and acquiring an initial value, a target value and an adjusting time length of the dimming process.
The initial value is a light value of the lamp at the beginning of the dimming process, and the light value may include, for example, at least one of a brightness value, a color temperature value, or other values known to those skilled in the art to characterize the light performance, and may be automatically obtained by a parameter obtaining module in the dimming device according to the current state of the lamp, which is not limited herein.
The target value is a light value of a lamp expected when the dimming process is finished, and can also be obtained by a parameter obtaining module in the dimming device, and the obtaining mode specifically includes automatically setting and obtaining according to the current environmental condition, or the target value can be input by a user, and correspondingly, the parameter obtaining module obtains the target value input by the user. For example, the target value may be input by a user in any manner known to those skilled in the art, such as manual input based on a screen for controlling the lamp, selection of a target gear based on a preset gear, input of a voice command based on a voice interaction manner, or other input, and the target value is determined accordingly, which is not limited herein.
The adjusting time duration is an expected time duration of the whole process that the light value of the lamp is changed from an initial value to a target value, and the expected time duration can also be obtained by a parameter obtaining module in the dimming device, and the obtaining mode specifically includes that the preset adjusting time duration in the lamp is directly called, or the preset adjusting time duration is determined and then called based on a difference value between the initial value and the target value and combined with a calculation method built in the lamp, or the preset adjusting time duration can be automatically input by a user and transmitted to the parameter obtaining module, correspondingly, the adjusting time duration is received by the parameter obtaining module, and the later can obtain the adjusting time duration in other modes known by a person skilled in the art, and the obtaining mode is not limited herein.
It can be understood that the initial value, the target value, and the adjustment duration may be set based on a scene change requirement, and may be any value that the lamp can satisfy, which is neither described nor limited herein.
S102: based on the adjustment duration, an adjustment phase is determined.
The adjusting stage comprises a first stage and a second stage, the first stage is prior to the second stage, the adjusting rate is increased in the first stage, and the adjusting rate is decreased in the second stage.
According to the arrangement, in the whole dimming process, the adjusting rate is not constant and changes along with time, and the whole dimming process has a changing trend of increasing firstly and then decreasing. From this, the process of adjusting luminance begins at a less regulation rate, and back crescent is reduced again to end at a less regulation rate, thereby realized the slow-start slow-stop of the process of adjusting luminance, be favorable to improving under the invariable regulation rate, because the problem of the pause and frustration that leads to of vision inertia exists, promote user experience.
Illustratively, as shown in fig. 3, a trend graph of the adjustment rate over adjustment time is provided for an embodiment of the present disclosure. Wherein the horizontal axis represents time t and the vertical axis represents the regulation rate Vt，VmaxRepresenting the maximum rate of regulation, VminRepresents the minimum regulation rate, VbRepresents the average modulation rate, T1Represents the first stage, T2Representing the second stage. As shown in FIG. 3, the adjustment period is divided intoTwo regulation phases, i.e. a first phase T1And a second stage T2(ii) a Wherein, the first stage T1Medium regulation rate VtGradually increase, second stage T2Medium regulation rate VtGradually decrease; first stage T1Is equal to the second stage T2Are the maximum regulation rate VmaxAnd a first stage T1Duration of and second stage T2Is equal to the adjustment duration. Therefore, in the whole dimming process, the dimming rate tends to increase and then decrease, and high dimming efficiency can be ensured while the slow start and slow stop are ensured.
It is understood that the adjusting time period shown in fig. 3 includes two adjusting stages only by way of example, but does not constitute a limitation to the dimming method provided by the embodiment of the present disclosure, and in other embodiments, the adjusting time period may further include three or more adjusting stages or sub-stages, which are exemplified in the following and are not limited thereto.
S103: based on the initial value, the target value and the adjustment phase, the adjustment rate of each adjustment phase is determined.
Wherein, the initial adjusting rate of the first stage and the ending adjusting rate of the second stage are both smaller than the preset rate threshold. So set up, can begin the dimming process with less regulation rate, and end the dimming process with less regulation rate to realize the slow-start slow-stop of dimming process, be favorable to improving the pause and frustrate of user's vision, promote user experience.
Optionally, the initial adjustment rate of the first phase and the final adjustment rate of the second phase may be equal or different, and may be set based on the requirement of the dimming method, which is not limited herein.
The preset rate threshold can be understood as a critical value that the eyes of the user can perceive the light variation, and below the critical value, the user cannot easily perceive the light variation, so that the problem of visual frustration is solved. For example, the preset rate threshold may be small, for example, may approach to 0, and thus the initial adjustment rate of the first phase and the termination adjustment rate of the second phase may approach to 0 or be 0, that is, the light variation value at the beginning and the end of the dimming process is small, and approaches to 0 or is 0, so that the light variation value may not be visually perceived by the user, thereby eliminating visual frustration of the user and improving the user experience.
The dimming method provided by the embodiment of the disclosure comprises the steps of obtaining an initial value, a target value and an adjusting time length of a dimming process; determining an adjustment stage based on the adjustment duration; the adjusting stage comprises a first stage and a second stage, wherein the first stage is prior to the second stage, the adjusting rate is increased in the first stage, and the adjusting rate is decreased in the second stage; determining the adjusting rate of each adjusting stage based on the initial value, the target value and the adjusting stage; wherein, the initial adjusting rate of the first stage and the ending adjusting rate of the second stage are both smaller than the preset rate threshold. Therefore, the adjusting stage can be determined based on the obtained adjusting duration, the adjusting stage comprises a first stage of increasing the adjusting rate and a second stage of decreasing the adjusting rate, and the first stage is prior to the second stage, so that in the dimming process of the lamp, the adjusting rate is wholly in a changing trend of increasing firstly and then decreasing, because the initial adjusting rate of the first stage and the termination adjusting rate of the second stage are both smaller than a preset rate threshold value, the light variation quantity at the beginning and the end of the dimming process is smaller, the slow start (including slow light) and slow stop (including slow light) of the dimming process are realized, the beginning and the end of the dimming process are easier to accept visually by a user, the visual frustration of the user in the dimming process is further improved, and the use experience of the user is improved.
In one embodiment, the lamp uses step dimming to adjust the light. With reference to fig. 3, a step time interval Δ t is preset in the lamp or set based on a demand, and the number of times N of light change in the whole dimming process can be calculated based on the adjustment duration and the step time interval Δ t; based on the initial value, the target value and the change times N in the dimming process, the average adjusting speed V of the light change can be determinedb(ii) a And the minimum regulation rate VminLess than the average regulation rate VbMaximum regulation rate VmaxGreater than the average regulation rate Vb(ii) a On the basis of this, the method is suitable for the production,according to the regulation requirement, the minimum regulation rate V can be determinedminAnd a maximum regulation rate Vmax. The control period can be arbitrarily divided into at least two control phases, as shown in FIG. 3, and can include a first phase T1And a second stage T2According to the first stage T1And a second stage T2Ratio in adjusting duration, minimum adjusting rate V of each stageminMaximum regulation rate VmaxAnd the change trend of the adjusting rate in each stage can obtain the adjusting rate at each moment in the dimming process, and then the change value of the light in the stepping time interval delta t is determined according to the adjusting rate at each different moment. Since the adjustment rates at different times may be different, the variation values of the light within the corresponding step time interval Δ t may also be different. Based on this, due to the first stage T1Initial rate of adjustment and second stage T2Is the minimum regulation rate of the phase to which it belongs, both of which are less than a preset rate threshold, then a first phase T1Initial rate of adjustment and second stage T2The stop adjusting rates of the lamp holders are small, for example, the stop adjusting rates can approach to 0, and the light change values of the corresponding lamps are relatively small, for example, the stop adjusting rates can approach to 0, so that a user cannot visually perceive the small light change values, visual frustration of the user is eliminated, and the use experience of the user is improved.
In the dimming method provided by the embodiment of the disclosure, the lamp is dimmed in a step dimming manner, the number of times N of light change in the whole dimming process can be calculated based on the adjustment duration and the step time interval Δ t, and N values of the adjustment rate corresponding to the step time interval Δ t exist in the adjustment duration. When the time corresponding to the stepping time interval Δ t is long enough, the broken line shown in fig. 3 may be correspondingly embodied in the form of a scatter diagram; when the step time interval delta t is small enough, the step time interval delta t is used as the reference when the user can not distinguish, and the step time interval delta t is small enough when the user can not distinguish, at the moment, the corresponding regulating speed V in the regulating time lengthtThe variation is embodied as a continuous polyline, as shown in fig. 3.
In other embodiments, the trend of the adjustment rate with the adjustment time may be further represented by at least one of a curve, a parabola or a straight line, which is not limited herein.
The beneficial effects of the dimming method provided by the embodiment of the present disclosure are exemplarily described below with reference to fig. 4.
Illustratively, as shown in fig. 4, a trend graph of a light value changing with an adjustment time in the dimming method provided by the embodiment of the present disclosure is provided. Wherein the vertical axis represents the light value LC and the horizontal axis represents the adjusting time t, LCfRepresenting the target value, LC0Representing the initial value. As shown in fig. 4, the lamp light value LC is changed from the initial value LC during the adjustment period T0Increase to the target value LCf. In connection with the above, the rate is adjusted to integrate with time, and the light value change trend can be obtained; correspondingly, the light value is derived from the time, and the adjusting rate can be obtained. With reference to fig. 3, since the dimming speed of the lamp is increased first during the dimming process (corresponding to the first period T)1) Post reduction (corresponding to the second stage T)2) Then the tangent slope of the change curve of the corresponding lamplight variable value LC is increased and then decreased; and because the corresponding rate of regulation is less when the dimming process begins and finishes, for example, can be close to 0 or equal to 0, the change value Δ LC of the corresponding light value LC is also very small, and it can be correspondingly close to 0 or equal to 0, so that the light value LC can change smoothly when the dimming process begins and finishes, and the user can not visually perceive the change value of the light, so that the visual sudden change can not be generated when the dimming process begins and finishes, and the visual frustration is eliminated.
In other embodiments, when the adjustment rate changes in other forms, the corresponding light value change trend changes, which is not limited herein.
In one embodiment, as shown in fig. 5, another trend graph of the adjusting rate with the adjusting time in the dimming method provided by the embodiment of the disclosure can be understood by referring to the explanation of fig. 3 above, except that the adjusting phase further includes a third phase T3. With reference to fig. 5, the adjustment phase also comprises a third phase T3Third stage T3Is connected to the first stage T1And a second stage T2(ii) a In a third phase T3In (1), the rate of adjustment remains constant; and a third stage T3Is equal to the first period T1And equal to the second phase T2The initial adjustment rate.
Wherein, in the whole adjusting time length corresponding to the dimming process, the adjusting stage can include a first stage T connected in sequence1The second stage T2And a third stage T3(ii) a Wherein, the first stage T1Starting at a smaller regulation rate (e.g. minimum regulation rate V)min) And a first stage T1With a gradual increase of the rate of medium adjustment, e.g. to a maximum rate of adjustment VmaxThereafter, the third stage T is entered3(ii) a Third stage T3The regulation rate is maintained at a maximum regulation rate Vmax; then, enter the second stage T2The regulation rate is initially gradually decreased and finally decreased at a smaller regulation rate (e.g., a minimum regulation rate V)min) And (6) ending. Due to the first stage T1Initial rate of adjustment and second stage T2The minimum regulation rate of the regulation stage is the minimum regulation rate of the regulation stage, and is the minimum regulation rate of the whole dimming process, so that the regulation rates of the dimming process at the beginning and at the end are smaller, the change value of the corresponding light is smaller, the change of the light cannot be perceived visually by a user, the visual inertia is avoided, the pause and frustration of the user visually are eliminated, and the user experience is improved.
It can be understood that fig. 5 only exemplarily shows that the adjustment duration in the dimming method includes three adjustment stages, but does not constitute a limitation of the dimming method provided by the embodiment of the present disclosure. In other embodiments, four, five or more adjustment phases or sub-phases may be included in the adjustment duration, which is not limited herein.
In the above embodiment, only the linear change of the adjustment rate is taken as an example, and the trend of the change in the adjustment rate during the dimming process, which is increased and then decreased, is described. In other embodiments, the change in the adjustment rate may also be configured as a non-linear change, such as at least one of an arc, curve, or parabola, as exemplified below in connection with fig. 6 and 7.
In one embodiment, as shown in fig. 6 or fig. 7, a trend graph of a further adjusting rate in a dimming method according to an embodiment of the present disclosure as a function of adjusting time can be understood with reference to the above explanation of fig. 3, except that the adjusting rate in at least one adjusting phase has a non-linear trend.

In one embodiment, referring to fig. 2 and 6, or to fig. 2 and 7, the second stage T2The regulation rate is linearly decreased (see fig. 2), or the regulation rate is parabolically decreased (see fig. 6 or fig. 7).
Wherein, the first stage T1The adjustment rate is linearly or parabolically increasing with the passage of the adjustment time; similarly, the second stage T2The adjustment rate is linearly or parabolically decreased with the time of adjustment, and the change trends of the adjustment rates of the two adjustment stages may be the same or different, and may be arbitrarily combined, which is not limited herein.
Illustratively, as shown in FIG. 6, a first phase T1In the second stage T, the regulation rate is increased parabolically2In (1), the regulation rate is decreased parabolically. Alternatively, as shown in FIG. 7, the first stage T1In (1), the rate of adjustment increases linearly; second stage T2In (1), the regulation rate is decreased parabolically.
