Based on the hardware architecture of the color temperature adjusting device of the lamp, the embodiment of the color temperature adjusting method of the lamp is provided.
Referring to fig. 2, fig. 2 is a first embodiment of the color temperature adjusting method of a lamp according to the present invention, which includes the steps of:
step S10, obtaining the rotation angle, rotation direction and rotation angular velocity of the knob, and determining the color temperature variation of the lamp according to the rotation angle;
in the present embodiment, the color temperature adjusting device whose subject is a lamp is implemented, and for convenience of description, the device is hereinafter referred to as the color temperature adjusting device of the lamp. The device is provided with a knob, please refer to fig. 3 specifically. The user can adjust the color temperature of the lamp by rotating the knob. The lamp refers to a dimming lamp, and the dimming lamp is used for adjusting the cold and warm color tones of the light source, namely adjusting the red and yellow and other warm colors of the lamp to the blue and other cold colors, or adjusting the blue and other cold colors of the lamp to the red and yellow and other warm colors. The dimming lamp can be a color-adjusting skylight, an environment lamp and a special photographic light supplement lamp.
The knob can be an electrodeless knob, namely the knob can rotate in two directions infinitely. When the knob is rotated, the device can detect the rotation angle of the knob. For example, the rotation shaft of the knob is engaged with the gear, the device records the rotation angle of the gear, and the rotation angle of the gear is the same as the rotation angle of the knob if the gear and the rotation shaft are the same in size. The device may also detect the direction of rotation of the knob and the rotational angular velocity.
The rotation direction is the direction in which the knob rotates, and the direction includes clockwise rotation and counterclockwise rotation.
The rotation angular velocity is the angle of rotation of the knob within the length of rotation. That is, the device starts timing when the knob starts to rotate and stops timing when the knob stops rotating, the obtained timing duration is the rotation duration of the knob, and the device divides the rotation angle of the knob by the rotation duration to obtain the knob duration of the knob.
In addition, the knob can be provided with a rotation gear, and the rotation of the knob is calculated by the gear, that is, the rotation angle is necessarily integral multiple of the angle corresponding to the gear. In this regard, the device may determine a first gear before the rotation of the knob and a second gear after the rotation of the knob, so as to determine the number of gear changes of the knob according to the first gear and the second gear, and each gear of the knob corresponds to a fixed angle. The angle corresponding to the gear is the rotation angle required for the knob to jump from the previous gear to the next gear. The product of the gear change number and the fixed angle is the rotation angle of the knob, namely the rotation angle of the knob is determined by the device according to the gear change number and the angle corresponding to the gear of the knob. For example, if the first gear is the 1 st gear and the second gear is the 6 th gear, the number of the knob changes to 5 gears, and the corresponding angle of each gear is 30 °, and the rotation angle of the knob is 150 °.
After the device determines the knob angle, the rotation direction and the rotation angular velocity of the knob, the device determines the color temperature variation according to the rotation angle. The color temperature change amount is an absolute value. The device stores a mapping relation between the rotation angle and the color temperature change amount, for example, the color temperature change amount corresponding to 1 ° is 5 k. If the rotation angle is 150 °, the color temperature variation is 750 k. If the calculation is carried out by the gear, the color temperature variation is 300k when the knob rotates one gear.
Step S20, correcting the color temperature change amount according to the rotational angular velocity;
in this embodiment, the device may display the current color temperature of the lamp, and the user may make adjustments based on the current color temperature. Based on the visualization of the color temperature, the rotational angular velocity may characterize the user's requirements for adjusting the color temperature. For example, the larger the rotation angular velocity, the faster the color temperature adjustment is required, i.e., the more eager the user is for color temperature adjustment, the most limited the amount of change in the color temperature of the device needs to be increased. It is understood that the larger the rotational angular velocity, the larger the magnitude of increase of the device with respect to the amount of change in color temperature. The device may determine a color temperature increment value according to the rotational angular velocity, the color temperature increment value being larger as the rotational angular velocity is larger, and the device increases the color temperature variation amount according to the color temperature increment value. In this regard, the device may correct the color temperature change amount based on the rotational angular velocity to obtain a corrected rotational angular velocity.
Step S30, determining a target color temperature according to the corrected color temperature variation, the current color temperature of the lamp and the rotation direction;
the rotation direction includes a color temperature increasing direction and a color temperature decreasing direction, for example, when the rotation direction is clockwise rotation, the rotation direction is a color temperature increasing direction; when the rotation direction is counterclockwise rotation, the rotation direction is a color temperature decreasing direction. When the rotating direction is the color temperature increasing direction, the device increases the current color temperature according to the corrected color temperature variation to obtain the target color temperature; and if the rotating direction is the color temperature reducing direction, reducing the current color temperature according to the corrected color temperature variation to obtain the target color temperature.
Step S40, adjusting the color temperature of the lamp to the target color temperature.
After the target color temperature is obtained, the device adjusts the color temperature of the lamp to the target color temperature, so that the color temperature of the lamp is adjusted.
In the technical solution provided in this embodiment, the color temperature adjusting device of the lamp acquires the rotation angle, the rotation direction, and the rotation angular velocity of the knob, determines the color temperature variation of the lamp according to the rotation angle, corrects the color temperature variation according to the rotation angular velocity, determines the target color temperature according to the corrected color temperature variation, the current color temperature of the lamp, and the rotation direction, and finally adjusts the color temperature of the lamp to the target color temperature. When the color temperature of the lamp is adjusted, the color temperature change amount corresponding to the rotation angle of the rotation angular velocity correction knob of the knob is introduced, and the rotation angular velocity of the knob represents the rapid adjustment requirement or the slow adjustment requirement of the user on the color temperature of the lamp, so that the color temperature adjusting device of the lamp achieves the purpose of flexibly adjusting the color temperature of the lamp according to the requirement of the user, and the flexibility of adjusting the color temperature of the lamp is improved.
Referring to fig. 4, fig. 4 is a second embodiment of the color temperature adjusting method of the lamp of the present invention, and based on the first embodiment, the step S20 includes:
step S21 of determining a compensation coefficient corresponding to the rotational angular velocity;
step S22 of determining a correction value based on the compensation coefficient and the rotational angular velocity;
and step S23, correcting the color temperature variation according to the correction value.
In this embodiment, the device is provided with a compensation coefficient corresponding to the rotational angular velocity. The compensation coefficient may be determined according to a section in which the rotational angular velocity is present, and the compensation coefficient may be increased as the value corresponding to the section is increased. In addition, the compensation coefficient can be determined according to the color temperature adjustment range value of the lamp, and the larger the color temperature adjustment range value is, the larger the compensation coefficient is, that is, the color temperature adjustment range value and the compensation coefficient are in a positive correlation relationship.
After the compensation coefficient is obtained, the device can determine a correction value according to the compensation coefficient and the rotation angular velocity. The correction value may be obtained by multiplying the rotation angular velocity by the coefficient. The device corrects the color temperature variation according to the correction value. For example, the corrected color temperature change amount Y is P1 × X + P2, where P1 is a compensation coefficient for an X angular velocity, X is a rotational angular velocity, and P2 is a basic shift position adjustment color temperature change amount. Examples are given below:
if the P1 compensation coefficient is set to be 1, the color temperature variation of P2 basic shift corresponding to the angle of one shift is set to be 300K, and the user rotates the knob by 1 shift in 50ms, which results in 360 degree angle variation, then the X rotation angular velocity: x360 degrees/0.05 seconds 720 degrees/second, the corrected output Y color temperature change amount: y1 × 720+300 — 1020K.
In the technical solution provided in this embodiment, the apparatus determines a compensation coefficient corresponding to the rotational angular velocity, and determines a correction value according to the compensation coefficient and the rotational angular velocity, thereby correcting the color temperature variation according to the correction value.
Referring to fig. 5, fig. 5 is a third embodiment of the color temperature adjusting method of the lamp according to the present invention, and based on the first or second embodiment, the step S20 includes:
a step S24 of determining whether the rotational angular velocity is greater than a first preset velocity;
a step S25 of increasing the color temperature variation amount according to the rotational angular velocity when the rotational angular velocity is greater than a first preset velocity;
and a step S26 of reducing the color temperature change amount according to the rotational angular velocity when the rotational angular velocity is smaller than a second preset velocity, the second preset velocity being smaller than the first preset velocity.
In the embodiment, the rotation angular velocity can reflect the requirement of the user for color temperature adjustment to some extent. The demand may be a fast adjustment demand or a slow adjustment demand, where the fast adjustment demand may be understood as a demand of a user to adjust the color temperature of the lamp to a target color temperature fast, and the slow adjustment demand may be understood as a demand of the user to adjust the color temperature of the lamp to the target color temperature accurately.
In this regard, the apparatus determines whether the rotational angular velocity is greater than a first preset velocity. If the rotational angular velocity is greater than the first preset velocity, it can be determined that the user has a requirement for rapidly increasing the color temperature, and the device increases the color temperature variation according to the rotational angular velocity, that is, the color temperature variation can be increased by Y-P1X + P2. If the rotation angular velocity is smaller than a second preset velocity, the color temperature variation is reduced according to the rotation angular velocity, and the second preset velocity is smaller than the first preset velocity. The device can reduce the color temperature variation by Y-P2-P1X.
When the rotation angular velocity is greater than or equal to the second preset velocity and less than or equal to the first preset velocity, the device does not need to correct the color temperature variation. The first predetermined speed and the second predetermined speed may be any suitable values, and the reduced color temperature variation is greater than or equal to zero when the rotation angular velocity is the second predetermined speed.
In the technical solution provided in this embodiment, the apparatus determines whether the rotational angular velocity is greater than a first preset velocity, and increases the amount of change in color temperature when the rotational angular velocity is greater than the first preset velocity; and if the rotation angular velocity is less than a second preset velocity, reducing the color temperature variation.
In one embodiment, the apparatus determines whether the color temperature variation of the lamp satisfies the correction condition after determining the color temperature variation according to the rotational angular velocity, and if the color temperature variation satisfies the correction condition, the apparatus needs to correct the color temperature variation according to the rotational angular velocity, and if the color temperature variation does not satisfy the correction condition, the apparatus directly adjusts the color temperature of the lamp according to the color temperature variation.
The correction condition includes at least one of:
1. the rotation angular speed of the knob is greater than a first preset speed;
2. the rotation angular speed of the knob is less than a second preset speed;
3. the difference value between the current color temperature and the limit color temperature of the lamp is larger than a first preset difference value, when the rotation direction is the color temperature increasing direction, the limit color temperature is the maximum color temperature of the lamp, and when the rotation direction is the color temperature decreasing direction, the limit color temperature is the minimum color temperature of the lamp;
4. the difference between the current color temperature and the limit color temperature of the lamp is smaller than a second preset difference, the limit color temperature is the maximum color temperature of the lamp when the rotation direction is the color temperature increasing direction, the limit color temperature is the minimum color temperature of the lamp when the rotation direction is the color temperature decreasing direction, and the first preset difference is larger than the second preset difference.
It should be noted that, the difference between the current color temperature and the limit color temperature of the lamp is greater than the first preset difference, that is, it can be determined that the adjustment width between the current color temperature and the maximum color temperature or the minimum color temperature of the lamp is large, and the user can perform rapid color temperature adjustment; and the difference between the current color temperature and the limit color temperature of the lamp is smaller than the second preset difference, namely the adjustment width between the current color temperature and the maximum color temperature or the minimum color temperature of the lamp can be determined to be smaller, and the user can adjust the color temperature with high precision.
