Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The lamp control method provided by the application can be applied to an application environment shown in fig. 1. Wherein the luminaire controller 102 communicates with the control platform 101 and the target luminaire 103. Specifically, when the user needs to control the target lamp 103, a corresponding control request may be triggered by the control platform 101, and then the control platform 101 may send the adjusted level control value to the lamp controller 102 corresponding to the target lamp 103 through a preset level control channel corresponding to the target lamp to be controlled in the target lamp, and the lamp controller 102 determines the target lamp in the target lamp 103 according to the level control channel receiving the level control value, and adjusts the level value of the color channel preset for the target lamp to the received level control value. The control platform 101 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the lamp controller 102 may be a control module for controlling the target lamp 103, where the target lamp 103 may be a multi-lens imaging effect lamp carrying a plurality of LED beads.
In one embodiment, as shown in fig. 2, a lamp control method is provided, and the method is applied to the lamp controller 102 in fig. 1 for illustration, and includes the following steps:
In step S201, the luminaire controller 102 determines a target lamp bead to be controlled from among the plurality of lamp beads of the target luminaire 103, and acquires a level control value for controlling the target lamp bead 103.
In this embodiment, the target lamp 103 may be a multi-lens imaging effect lamp with multiple beads, the structure of which may be shown in fig. 3 and 4, where the target lamp 103 in fig. 3 may carry 19 LED beads, the target lamp 103 in fig. 4 may carry 37 LED beads, and all the beads in the target lamp 103 carry corresponding bead position numbers for representing different beads in the target lamp 103. The target lamp beads refer to the lamp beads to be controlled among the plurality of lamp beads carried by the target lamp 103, and the lamp controller 102 can control the target lamp 103 only for one or more lamp beads, and the lamp beads to be controlled can be used as the target lamp beads. For example, for the target lamp 103 with 19 LED beads in fig. 3, if only the 10 th and 16 th beads need to be controlled, the 10 th and 16 th beads can be used as target beads, and if all the beads of the target lamp 103 need to be controlled, then all the beads carried by the target lamp 103 can be used as target beads. The level control value refers to a value required to control the level value of the target lamp bead, the value may be set by a user according to actual needs, the user may input the target lamp bead in the target lamp 103 required to be controlled and the level control value for controlling each target lamp bead through the control platform 101, and send the level control value to the lamp controller 102, and the lamp controller 102 may determine the target lamp bead required to be controlled and the level control value for controlling each target lamp bead according to the received control signal.
In step S202, the luminaire controller 102 determines a preset color channel, and adjusts the current level value of the target lamp bead for the color channel to a level control value.
The color channels may be channels for storing color information of light emitted by the lamp beads, and the lamp controller 102 may change the level value of each color channel of the lamp beads in the target lamp 103 to achieve the effect of color adjustment, and the preset color channel refers to a preset color channel that can be used for adjusting the level value to change the color of the lamp beads. For example, the bead of the target lamp 103 may include four color channels RGBW, and the preset color channel may be one of the four color channels, for example, may be an R channel. Specifically, after determining the target lamp and the level control value for controlling the target lamp, the lamp controller 102 may adjust the level value of the preset color channel in the target lamp to the level control value.
Taking the target lamp 103 with 19 LED beads in fig. 3 as an example, if the target beads are 10 and 16, the lamp controller 102 may determine the level control values corresponding to the 10 and 16 beads respectively, then adjust the level values of the 10 and 16 beads to the corresponding level control values in the preset color channel, for example, the preset color channel may be an R channel, and then the lamp controller 102 may adjust the current level values of the 10 and 16 beads to the corresponding level control values in the R channel to adjust the color display of the 10 and 16 beads.
In the above-mentioned lamp control method, the lamp controller 102 of the target lamp carrying a plurality of lamp beads determines a target lamp bead to be controlled from a plurality of lamp beads of the target lamp 103, and obtains a level control value for controlling the target lamp bead; and determining a preset color channel, and adjusting the current level value of the target lamp bead aiming at the color channel to be a level control value. Compared with the prior art that the lamp control is realized through a color correction system, the application can reduce the control cost, simultaneously avoid the reduction of light output and further improve the illuminance value of the lamp.
In one embodiment, as shown in fig. 5, before step S202, the method may further include:
In step S501, the luminaire controller 102 obtains a white light balance level value of each of the light beads for the color channel in the white light balance state of the target luminaire 103.
The white light balance state refers to a state that each of the light beads in the target light 103 is displayed with the same color, and because the light beads of the target light 103 may be different in doing work or use time, if all run with the maximum level value, the color display of each light bead may not be completely the same, for example, a certain light bead may emit a reddish color or bluish color, etc., so in order to make the target light 103 in a white light balance state that each light bead emits the same color, the level value of the preset color channel of each light bead in the target light 103 may be set in advance, and under this level value running, the target light 103 may be in the white light balance state. The setting method may be that a technician sets the level value of all the lamp beads in the target lamp 103 to be the maximum in advance, and covers a new white "printing paper" on the lens disc of the lamp, finds out the lamp beads with inconsistent colors by observing the RGBW superimposed colors of the lamp beads through the "printing paper", adjusts the level value, and after the target lamp 103 is in the white light balance state, can record the level value of each lamp bead after adjustment as the white light balance level value.
In step S502, the luminaire controller 102 takes the white light balance level value of the target lamp bead for the color channel as the current level value.
Then, the lamp controller 102 may use the white light balance level value of the target lamp as the current level value of the target lamp, i.e. the default level value after the level value is not controlled. Specifically, when the lamp controller 102 determines the white light balance level value corresponding to each target lamp bead, the white light balance level value may be stored, and when the target lamp 103 is powered off and restarted, the white light balance level value may be read as the current level value of each lamp bead.
In this embodiment, the white light balance level value of the target lamp may be set, so that the target lamp 103 may operate with the white light balance level value as the current level value during normal operation, and further the target lamp 103 may be in a white light balance state, and the color correction system is not required.
Further, step S202 may further include: if the level control value is smaller than the white light balance level value, the lamp controller 102 adjusts the current level value of the target lamp bead for the color channel to be the level control value; and/or if the level control value is greater than the white light balance level value, the lamp controller 102 masks the level control value and keeps the level value of the target lamp bead for the color channel as the current level value.
In this embodiment, the adjustment of the current level value in step S202 may also be to compare the adjusted level control value with a preset white light balance level value, in this embodiment, since the white light balance level value corresponding to each bead in the target lamp 103 is preset, the white light balance level value may be a preset maximum level threshold for the bead in the preset color channel, when the adjusted level control value is greater than the preset maximum level threshold, the lamp controller 102 may shield the level control value, and still keep the level value of the current operation of the target bead, and only when the level control value is less than the preset white light balance level value, the lamp controller 102 will adjust the current level value to the level control value.
For example, the white light balance level value of a certain target lamp bead set in advance may be 250, if the current target lamp bead has the white light balance level value as the current level value and the received level control value is 230, the lamp controller 102 may adjust the level value of the target lamp bead in the set color channel from 250 to 230, and if the received level control value is 251, since the white light balance level value 250 has been exceeded, the lamp controller 102 may mask the adjustment of the level value control and still maintain the white light balance level value 250.
In this embodiment, the white light balance level value of the target lamp bead can also be used as the maximum level threshold of the target lamp bead, and when the level control value is greater than the white light balance level value, the lamp controller 102 can shield the control of the level value, so as to ensure the color consistency of the target lamp 103.
In one embodiment, the white light balance level value of the target lamp bead for the color channel is less than or equal to the maximum level value of the target lamp bead for the color channel; step S201 may further include: the lamp controller 102 determines channel level data corresponding to a preset lamp control function channel; when the channel level data meet the preset condition, taking the maximum level value as a level control value; step S202 may further include: the luminaire controller 102 adjusts the current level value of the target lamp bead for the color channel to a maximum level value.
The maximum level value refers to a maximum level value of a target lamp bead in a certain preset color channel, for example, for a certain color channel, the corresponding channel level may be 0-255, and in order to make the target lamp 103 be in a white light balance state, a user may attenuate the maximum level of some lamp beads in the target lamp 103 in the color channel through the control platform, and may attenuate the maximum level value of a certain lamp bead to 250 as a white light balance level value. Therefore, the white light balance level value of the lamp bead of the target lamp 103 in the set color channel is less than or equal to the maximum level value.
At this time, if in some special cases, when the user needs to operate some of the light beads of the target light fixture 103 with the maximum level value, the corresponding channel level data may be sent through the functional channel preset by the control platform 101, and after the light fixture controller 102 determines the channel level data of the functional channel, it may be determined whether the channel level data meets a certain preset condition, where the condition may be that the user sets the channel level data according to needs, only when the channel level data meets the condition, the limitation that the target light fixture 103 uses the white light balance level value of each light bead as the maximum operation level of each light bead in the preset color channel is released, and the maximum level value is adopted as the maximum operation level in the preset color channel.
For example, in the case of normal operation, the maximum operating level of a certain light bulb in the preset color channel may be 250, and if the user wants to remove the limitation of the maximum operating level of the light bulb and operate the light bulb with the maximum level value of 255, a certain function channel preset by the control platform 101 is needed, channel level data meeting a certain preset condition is triggered through the function channel, the preset condition may be that the level data of the function channel is stabilized to 105 and lasts for 5 seconds, at this time, when the channel level data of the function channel received by the light fixture controller 102 is stabilized to 105 and lasts for 5 seconds, the limitation of the maximum operating level of the target light bulb in the preset color channel in the target light fixture 103 may be removed, that is, the maximum operating level of the light bulb is restored to 255 from 250, and the current level value of the target light bulb in the color channel is adjusted to 255, that is, the maximum level value.
In this embodiment, the target lamp beads can be operated at the maximum level by the preset functional channels and by making the channel level data corresponding to the functional channels satisfy a certain preset condition, so as to improve the applicable range of the target lamp 103.
In addition, the luminaire controller 102 may further control an imaging effect of the luminaire, that is, may control whether the target luminaire 103 operates in an imaging mode or in a non-imaging mode, specifically, the control platform 101 may further preset a certain image channel, when a user needs to switch the imaging mode of the target luminaire 103, the corresponding level data may be triggered through the image channel of the control platform 101, and when the level data meets a certain condition, the imaging mode of the target luminaire 103 may be switched. For example, when the interval of the level data of the image channel belongs to 8-255, then the luminaire controller 102 may control the target luminaire 103 to operate in the imaging mode, and if the interval of the level data of the image channel belongs to 0-7, then the luminaire controller 102 may control the target luminaire 103 to operate in the non-imaging in-focus mode.
In this embodiment, the switching control of the imaging mode of the target lamp can also be realized through the level data of the image channel, and by setting the interval of the level data, when the lamp controller 102 reads that the level data of the image channel meets the corresponding interval, it can be determined whether the working mode to be executed by the target lamp 103 is the imaging mode or the non-imaging in-focus mode, thereby realizing the imaging control of the target lamp 103 and further improving the applicability of the lamp.
In one embodiment, the white light balance level value of the target lamp bead for the color channel is less than or equal to the maximum level value of the target lamp bead for the color channel; when the lamp temperature of the target lamp is greater than the preset temperature threshold, step S201 may further include: the lamp controller 102 determines a lamp bead with a white light balance level value smaller than a maximum level value from a plurality of lamp beads of the target lamp 103 as a target lamp bead, and takes the maximum level value as a level control value; step S203 may further include: the luminaire controller 102 adjusts the current level value of the target lamp bead for the color channel to a maximum level value.
In this embodiment, the white light balance level value of the target lamp 103 in the set color channel is smaller than or equal to the maximum level value, and meanwhile, the target lamp 103 may cause a natural attenuation phenomenon due to the temperature rise caused by long-time lighting, and meanwhile, the non-uniformity of the RGBW superimposed colors is aggravated when the attenuation phenomenon occurs due to the different level threshold value, i.e., the white light balance level value, of each lamp in the preset color channel. Therefore, in order to meet the high-temperature use scenario, the present embodiment may temporarily mask the preset white light balance level value of each lamp bead of the target lamp 103 when the temperature of the target lamp 103 is too high, and operate the white light balance level value at the maximum level value.
Specifically, when the lamp controller 102 detects that the temperature of the target lamp 103 is greater than the preset temperature threshold, that is, when the temperature of the target lamp is higher at this time, the lamp beads with the white light balance level value smaller than the maximum level value can be selected from the plurality of lamp beads of the target lamp 103 as target lamp beads, that is, the lamp beads with the maximum level attenuated in advance are selected as target lamp beads, and the maximum level value is used as a level control value, so that all the lamp beads in the target lamp 103 can operate in the preset color channel through the maximum level value.
For example, the set temperature threshold may be 60 degrees, and when the lamp controller 102 detects that the temperature of the target lamp 103 is greater than 60 degrees, a lamp bead with a white light balance level value smaller than a maximum level value may be selected from a plurality of lamp beads of the target lamp 103 as a target lamp bead, and the level value of the target lamp bead in a preset color channel is adjusted from the white light balance level value to the maximum level value, so as to implement attenuation compensation.
Further, after the lamp controller 102 adjusts the current level value of the target lamp bead for the color channel to the maximum level value, the method further includes: when the lamp temperature of the target lamp 103 falls below the temperature threshold, the lamp controller 102 restores the current level value of the target lamp bead for the color channel from the maximum level value to the white light balance level value.
Meanwhile, in order to avoid damage to the target lamp 103 caused by long-term maintenance of high-temperature operation, the target lamp 103 may be further subjected to cooling control by the lamp controller 102, for example, a cooling fan may be disposed in the target lamp 103, and the operation of the cooling fan may be controlled by the lamp controller 102 to reduce the operating temperature of the target lamp 103. The lamp controller 102 may send an instruction to decrease the output power to the target lamp 103, and decrease the PWM duty cycle output of the target lamp 103 to decrease the temperature of the target lamp 103. If the temperature of the target lamp 103 drops to the set temperature threshold, the lamp controller 102 may restore the current level value of the target lamp bead in the color channel from the maximum level value to the white light balance level value again, so as to maintain the white light balance state of the target lamp 103.
In this embodiment, the lamp controller 102 may also control the level value of the lamp bead in the target lamp 103 in the preset color channel to be the maximum level value when the temperature of the target lamp 103 is greater than the set temperature threshold value, so as to compensate for the attenuation phenomenon caused by the temperature rise, and may also restore the maximum level value to the white light balance level value when the temperature drops, so as to maintain the white light balance state of the target lamp 103.
In one embodiment, there is also provided a luminaire control system, as shown in fig. 6, which may include: a luminaire controller 602 carrying a target luminaire 603 of a plurality of beads, and a control platform 601 in communication with the luminaire controller 602; wherein,
The control platform 601 is configured to obtain a target lamp bead to be controlled corresponding to a control request in response to the control request of the control target lamp 603, and a level control value for controlling the target lamp bead, and send the level control value of the target lamp bead to the lamp controller through a preset level control channel corresponding to the target lamp bead;
The lamp controller 602 is configured to receive a level control value from the level control channel, determine a target lamp bead from a plurality of lamp beads of the target lamp 603 according to the level control channel, and use the level control value in the level control channel as a level control value for controlling the target lamp bead;
The luminaire controller 602 is further configured to determine a preset color channel, and adjust a current level value of the target lamp bead for the color channel to a level control value.
In the lamp control system provided in this embodiment, when a user needs to control a target lamp 603 with a plurality of lamp beads, a control request can be triggered by the control platform 601, where the control request can carry the target lamp beads to be controlled and a level control value for controlling the target lamp beads, and after the control platform 601 determines the target lamp beads, the level control value can be sent to the lamp controller 602 through a level control channel adapted to the target lamp beads.
The lamp controller 602 may receive the level control value sent by the control platform 601 from the corresponding level control channel, determine the corresponding target lamp bead from the plurality of lamp beads of the target lamp 603 according to the level control channel, and adjust the level value of the target lamp bead in the set color channel to the level control value, so as to realize the control of the target lamp 603.
In the lamp control system, the lamp controller 602 can control the level of the preset color channel of the target lamp bead to be controlled in the target lamp 603, so that the lamp control is realized.
In an application example, a system and a method for controlling a multi-lens imaging effect lamp are also provided, and the specific scheme can be as follows:
1. the R maximum channel level threshold value of each LED in the lamp is independently set through the display panel, so that white light is balanced when RGBW of each LED in the lamp is overlapped with colors, deviation is not large, and scene application of light emission consistency is met.
The application can be applied to 19 or 37 four-in-one multi-lens 'point control' imaging effect lamps, R colors of each LED are independently and properly subjected to dimming treatment (namely, a R maximum channel level threshold value is limited) through a 'zero adjustment' menu of a display panel, and an EEPROM circuit in the display panel memorizes and saves the R maximum color threshold value so as to ensure that data is called after the lamp is powered off and restarted. When the RGBW superposition color of the lamp emits light and different pattern effects are emitted, the RGBW superposition color of the pattern is balanced in white light, and the deviation is not large.
The specific implementation method of the patent is
(1) RGBW of a multi-lens 'point control' imaging effect lamp is set to be fully bright (namely, the channel level of each color is set to be 255), and the focusing stroke is set to be maximum (namely, each LED is in an imaging state), then a technician covers a new white 'printing paper' on a lamp lens disc, and observes the RGBW superposition color of each LED penetrating through the 'printing paper'.
(2) When confirming that the LEDs with certain position numbers need zero adjustment data, the submenus of the corresponding position numbers such as the submenu LED1 lamp bead R, the submenu LED2 lamp bead R, the submenu LED3 lamp bead R and the like in the zero adjustment menu of the display panel are searched. By looking up the LED bit number quickly, for example, by setting R of a certain LED to 0 (the default value is FFFF) in a submenu, the RGBW superimposed color of that LED will change significantly. And so on to find the LED bit number to be adjusted.
(3) Appropriate dimming data (i.e., determining the level threshold of the rmax channel) is set by the DOWN key or the UP key, and the change of the white light color superimposed by the LED of the corresponding bit number is observed in real time. Since the R color channel level of each LED is 0-255 and the R color also has a fine tuning channel level of 0-255, we convert it to 16-bit binary data FFFF (FFFF is the default maximum value), which allows the R maximum channel level threshold of each LED to be more finely tuned.
For example: as shown in fig. 7, the R maximum threshold of a certain LED is reduced from FFFF (the decimal number is 65535) to FD80 (the decimal number is 64896), that is, 64896 to 65535 are invalid data, even if the console transmits channel level data of 0-65535, which varies, through the DMX512 signal line, the display panel receives only 0-64896 channel level data or the display panel transmits only 0-64896 channel level data through the RS485 signal line.
(4) The data is saved through the ENTER key, and the EEPROM circuit of the display panel can memorize and save the equivalent data.
2. The white light balance data when RGBW of each LED is overlapped with colors is temporarily shielded through the functional channel of the console, so that the lamp can output maximum brightness to meet the scene application with high illumination requirement.
Before each LED lamp leaves the factory, the white light balance data during RGBW superposition is set, and besides the pattern effect function, the WASH function with zooming (namely, the LEDs are not in the imaging effect) can also be used. In the pattern effect function, we have suitably dimmed the R color of each LED individually in the luminaire. Therefore, when the RGBW is fully bright, the whole light spot of the lamp has two types of white light blue or white pink light red. Also their illuminance will be biased, especially the value of the illuminance at which the lamp emits light at the minimum angle. At this time, the display panel of the lamp detects the channel level data of the pattern channel and the functional channel sent by the console, and judges whether to output the maximum brightness. There are three descriptions, specifically as follows:
(1) When the pattern channel value is 8-255, the lamp switches the pattern effect function, and the lamp takes the white light balance data stored in the EEPROM circuit when RGBW is overlapped as a reference.
(2) When the pattern channel value is 0-7, the lamp is switched to have the focusing WASH effect, and the lamp is still based on the white light balance data stored by the EEPROM circuit when RGBW is overlapped.
(3) When using the WASH function with zoom, and the lamp output maximum brightness is required. After 5 seconds of stay, the lamp temporarily masks the white light balance data when RGBW is superimposed, with the "functional channel" of the console set to 105. That is, the lamps are set to not limit the maximum threshold value of R color, and the maximum channel level data of R in the DMX512 cache data is received, and the EEPROM circuit in the display panel does not store the maximum channel level data of R color.
3. The PN node of the R color can generate a great natural attenuation phenomenon along with the temperature rise, the display panel can temporarily shield white light balance data when RGBW of each LED is overlapped with the color according to the temperature fed back by the thermistor, and the R color is subjected to attenuation compensation so as to meet the scene application in a high-temperature environment.
When the temperature of the LED rises due to the long-time lighting, in which the R-color wafer is relatively sensitive to temperature, it may exhibit a large natural decay phenomenon. Before each LED lamp leaves the factory, white light balance data when RGBW of each LED is overlapped with colors are set. For example, the 1 st bead R is set to FFFF, the 8 th bead R is set to FD80, the 11 th bead R is set to FC10, and the 18 th bead R is set to FA30. Since the maximum value of the R color of each LED is different, when the R color is attenuated due to the temperature rise, the inconsistency in superimposing colors of RGBW is aggravated. At this time, the display panel temporarily shields white light balance data of each LED when RGBW overlaps colors according to the temperature fed back by the thermistor, and performs attenuation compensation on R colors.
When the feedback temperature of the current display panel is 45, the heat dissipation fan of the LED lamp starts to rotate, and the rotation voltage of the fan can be increased along with the rising of the feedback temperature. When the feedback temperature of the display panel is 60-65 ℃, the display panel can temporarily shield white light balance data when RGBW of each LED is overlapped with colors, and attenuation compensation is carried out on R colors. When the feedback temperature of the display panel is lower than 60 ℃, the display panel can recover the white light balance data when RGBW of each LED is overlapped with colors. When the feedback temperature of the display panel is 75 ℃, the display panel sends a power-down instruction through RS485, and the MCU controlling the LEDs properly reduces the output of the PWM duty ratio according to the instruction, so as to maintain the heat balance of the lamp.
4. When a certain desk lamp is used after sale for a long time and the light is attenuated or part of the desk lamp is replaced to damage the LEDs, after-sale technicians need to readjust the RGBW superposition color of each LED through the display panel, so that the scene application of after-sale lamp maintenance is met.
Because the LED lamp is used for a long time after leaving the factory, the aging or light attenuation of each LED in the lamp is different, and the deviation of white light balance data when the original RGBW is overlapped with the color is possibly caused. In order to facilitate the operation of the after-sales technicians, an R maximum sub-menu and an R viewing sub-menu are added in the zero adjustment menu of the display panel.
If the function "all Rmax" is used, the lamp can output maximum brightness, and the EEPROM circuit in the display panel can store the maximum threshold data.
If the function of checking all R is used, the lamp can display the threshold value of all R currently in the interface of the display panel, which is helpful for the statistics of big data of the lamp and the quick acquisition of the original or current set data of the lamp by the after-sales technician.
If the function of restoring factory settings is used, the lamp can restore white light balance data when RGBW (red, green and blue) superimposed colors set before factory setting.
