Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The lamp control method provided by the application can be applied to the application environment shown in fig. 1. The luminaire controller 102 communicates with the control platform 101 and the target luminaire 103. Specifically, when a user needs to control the target lamp 103, a corresponding control request may be triggered by the control platform 101, the control platform 101 may send an adjusted level control value to the lamp controller 102 corresponding to the target lamp 103 through a preset level control channel corresponding to a target lamp bead that needs to be controlled in the target lamp, and the lamp controller 102 determines the target lamp bead in the target lamp 103 according to the level control channel that receives the level control value and adjusts a level value of a color channel that is preset for the target lamp bead to the received level control value. The control platform 101 may be but not limited to various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, the lamp controller 102 may be a control module for controlling the target lamp 103, and the target lamp 103 may be a multi-lens imaging effect lamp with a plurality of LED lamp beads.
In one embodiment, as shown in fig. 2, a luminaire control method is provided, which is described by taking the application of the method to the luminaire controller 102 in fig. 1 as an example, and includes the following steps:
in step S201, the lamp controller 102 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 103.
In this embodiment, the target lamp 103 may be a multi-lens imaging effect lamp with multiple lamp beads, and the structure of the target lamp may be as shown in fig. 3 and fig. 4, where the target lamp 103 in fig. 3 may carry 19 LED lamp beads, the target lamp 103 in fig. 4 may carry 37 LED lamp beads, and all the lamp beads in the target lamp 103 carry corresponding lamp bead position numbers for representing different lamp beads in the target lamp 103. The target lamp bead refers to a lamp bead that needs to be controlled among a plurality of lamp beads carried by the target lamp 103, and the lamp controller 102 may control the target lamp 103 by performing corresponding control only on one or more of the lamp beads, and the lamp bead that needs to be controlled may be the target lamp bead. For example, for the target lighting fixture 103 carrying 19 LED beads in fig. 3, if only 10 beads and 16 beads need to be controlled, the 10 beads and 16 beads may be used as target beads, and if all beads of the target lighting fixture 103 need to be controlled, the target beads may be all beads carried by the target lighting fixture 103. The level control value refers to a value that needs to control the level value of the target lamp bead, and 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 that needs to be controlled through the control platform 101 and the level control value for controlling each target lamp bead, and send the level control value to the lamp controller 102, and the lamp controller 102 may determine the target lamp bead that needs to be controlled according to the received control signal and the level control value for controlling each target lamp bead.
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 channel may be a channel for storing light emitting color information of a lamp bead, the lighting fixture controller 102 may change a level value of each color channel of the lamp bead in the target lighting fixture 103 to achieve a color adjustment effect, and the preset color channel refers to a preset color channel that can be used to adjust the level value to change a color of the lamp bead. For example, the lamp bead of the target luminaire 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 the lamp controller 102 determines the target lamp bead and the level control value for controlling the target lamp bead, the level value of the preset color channel in the target lamp bead may be adjusted to the level control value.
Taking the target lamp 103 with 19 LED lamp beads in fig. 3 as an example, if the target lamp beads are number 10 lamp beads and number 16 lamp beads, the lamp controller 102 may respectively determine the level control value corresponding to the number 10 lamp beads and the level control value corresponding to the number 16 lamp beads, and then may adjust the level values of the number 10 lamp beads and the number 16 lamp 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 on the number 10 lamp beads and the number 16 lamp beads R channel to the corresponding level control values to adjust the color display of the number 10 lamp beads and the number 16 lamp beads.
In the lamp control method, the lamp controller 102 of the target lamp with a plurality of lamp beads determines the target lamp bead to be controlled from the 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 for the color channel to be a level control value. This application is through lamps and lanterns controller 102, and the level of predetermineeing the colour channel to the target lamp pearl that needs to control in the target lamps and lanterns 103 is controlled to realized the control of lamps and lanterns, compared in prior art and need go to realize lamps and lanterns control through colour correction system, when this application can reduce control cost, can also avoid the reduction of light output, thereby improve the illumination value of lamps and lanterns.
In one embodiment, as shown in fig. 5, before step S202, the method may further include:
in step S501, the lighting device controller 102 obtains a preset white light balance level value of each lamp bead of the target lighting device 103 in a white light balance state for the color channel.
The white light balance state refers to a state in which each lamp bead in the target lamp 103 displays in the same color, and since each lamp bead of the target lamp 103 may be operated at a maximum level value due to different operations or different lengths of use time, color display of each lamp bead may be not completely the same, for example, a color that a certain lamp bead may emit may be red or blue, and so on, in order to enable the target lamp 103 to be in a white light balance state in which each lamp bead emits the same color, a level value of a preset color channel of each lamp bead in the target lamp 103 may be set in advance, and the target lamp 103 may be in the white light balance state under the operation of the level value. The setting method may be that a technician sets the level values of all lamp beads in the target lamp 103 to be maximum in advance, covers a new piece of white printing paper on the lamp lens disc, finds out lamp beads with inconsistent colors by observing RGBW superposition colors of the printing paper on the lamp beads, and adjusts the level values of the lamp beads, and after the target lamp 103 is in a white light balance state, the adjusted level values of the lamp beads can be recorded as white light balance level values.
In step S502, the luminaire controller 102 sets the white light balance level value of the target bead for the color channel as the current level value.
Then, the lighting fixture controller 102 may use the white light balance level value of the target lamp bead as the current level value of the target lamp bead, that is, the default level value after the level value control is not performed. 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 out 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 when operating normally, and the target lamp 103 may be in a white light balance state without using a color correction system.
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 a comparison of a magnitude relationship between the adjusted level control value and a preset white light balance level value, in this embodiment, because the white light balance level value corresponding to each lamp bead in the target lamp 103 is preset, the white light balance level value may be a preset maximum level threshold value for the lamp bead in a preset color channel, when the adjusted level control value is greater than the set maximum level threshold value, the lamp controller 102 may shield the level control value, and still keep the level value of the target lamp bead in current operation, and only when the level control value is less than the set white light balance level value, the lamp controller 102 may adjust the current level value to the level control value.
For example, the preset white light balance level value of a certain target lamp bead may be 250, if the current target lamp bead uses the white light balance level value as the current level value, and the received level control value is 230, then the luminaire 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 is already exceeded, then the luminaire controller 102 may mask the adjustment of the level value control this time, and still maintain the white light balance level value 250.
In this embodiment, the white light balance level value of the target lamp bead may 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 may shield the control of the level value, thereby ensuring 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 conditions, 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 bead for the color channel to the maximum level value.
The maximum level value refers to a maximum level value of a target lamp bead in a preset color channel, for example, for a certain color channel, the corresponding channel level may be 0-255, and in order to enable the target lamp 103 to 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, or attenuate the maximum level value of a certain lamp bead to 250 as a white light balance level value. Therefore, the white 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, a user needs to operate some lamp beads of the target lamp 103 at the maximum level value, the user may send corresponding channel level data through the function channel preset by the control platform 101, and after the lamp controller 102 determines the channel level data of the function 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 condition as needed, and only when the channel level data meets the condition, the target lamp 103 removes the limitation that the white light balance level value of each lamp bead is used as the maximum operation level of each lamp bead in the preset color channel, and takes the maximum level value as the maximum operation level in the preset color channel.
For example, if a white light balance level value corresponding to a certain lamp bead is 250, in a normal operation situation, the maximum operation level of the lamp bead in the preset color channel may be 250, and if a user wishes to remove the limitation on the maximum operation level of the lamp bead and operates the lamp bead at the maximum level value of 255, a certain function channel preset by the control platform 101 is required, and channel level data meeting a certain preset condition is triggered through the function channel, where 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 luminaire controller 102 is stabilized to 105 and lasts for 5 seconds, the maximum operation level limitation on the preset color channel of the target lamp bead in the target luminaire 103 may be removed, that is, the maximum operation level of the lamp bead is recovered from 250 to 255, and the current level value of the target lamp bead in the color channel is adjusted to be 255, namely the maximum level value.
In this embodiment, when the corresponding channel level data of the function channel satisfies a predetermined condition, the target lamp bead may be operated at the maximum level through the preset function channel, so as to improve the applicable range of the target lamp 103.
In addition, the lamp controller 102 may also control an imaging effect of the lamp, that is, may control whether the target lamp 103 operates in an imaging mode or a non-imaging mode, specifically, the control platform 101 may also be preset with a certain image channel, when a user needs to switch the imaging mode of the target lamp 103, 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 lamp 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, switching control of the target lamp imaging mode may also be achieved 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 satisfies the corresponding interval, it may be determined whether the working mode that the target lamp 103 needs to execute is the imaging mode or the non-imaging in-focus mode, thereby achieving imaging control of the target lamp 103 and further improving 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 the maximum level value from the plurality of lamp beads of the target lamp 103 as a target lamp bead, and uses 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 bead for the color channel to the maximum level value.
In this embodiment, the white light balance level value of the target lamp 103 in the 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 rise of temperature caused by long-time lighting, and meanwhile, since the level threshold value of each lamp bead set in the preset color channel is different, that is, the white light balance level value is different, when the attenuation phenomenon occurs due to the rise of temperature, the inconsistency when RGBW colors are superimposed is aggravated. Therefore, in order to meet the high-temperature usage scenario, in this embodiment, when the temperature of the target lamp 103 is too high, the preset white light balance level value of each lamp bead of the target lamp 103 may be temporarily shielded, and the target lamp 103 may be operated at the maximum level value.
Specifically, when the lamp controller 102 detects that the temperature of the target lamp 103 is greater than a preset temperature threshold, that is, the temperature of the target lamp is higher at this time, it may screen out, from the multiple lamp beads of the target lamp 103, a lamp bead whose white light balance level value is smaller than the maximum level value as a target lamp bead, that is, screen out a lamp bead that attenuates the maximum level in advance as a target lamp bead, and use the maximum level value as a level control value, so that all lamp beads in the target lamp 103 can operate through the maximum level value in a preset color channel.
For example, the set temperature threshold may be 60 degrees, when the lighting fixture controller 102 detects that the temperature of the target lighting fixture 103 is greater than 60 degrees, a lamp bead with a white light balance level value smaller than the maximum level value may be screened out from a plurality of lamp beads of the target lighting fixture 103 as a target lamp bead, and the level value of the target lamp bead in the 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 luminaire controller 102 adjusts the current level value of the target bead for the color channel to the maximum level value, the method further includes: when the fixture temperature of the target fixture 103 falls below the temperature threshold, the fixture controller 102 restores the current level value of the target beads for the color channels from the maximum level value to the white light balance level value.
Meanwhile, in order to avoid the target lamp 103 from being damaged due to long-term high-temperature operation, the lamp controller 102 may further perform cooling control on the target lamp 103, for example, a cooling fan may be disposed in the target lamp 103, and the lamp controller 102 controls the operation of the cooling fan 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 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 to maintain the white light balance state of the target lamp 103.
In this embodiment, the lamp controller 102 may further control a level value of a bead in the target lamp 103 in a preset color channel to be a maximum level value when the temperature of the target lamp 103 is greater than the set temperature threshold, so as to compensate for the attenuation phenomenon caused by the temperature increase, and meanwhile, after the temperature decreases, the maximum level value may be restored to a white light balance level value, so as to maintain the white light balance state of the target lamp 103.

In an application example, a multi-lens imaging effect lamp control system and a method are also provided, and the specific scheme can be as follows:
1. the R maximum channel level threshold 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 superposed with color, and deviation is not large, so that scene application with high light emitting consistency is met.
The LED dimming control system can be applied to 19 or 37 40W four-in-one multi-lens point control imaging effect lamps, the R color of each LED is subjected to proper dimming treatment independently (namely the R maximum channel level threshold value is limited) through a zero adjustment menu of the display panel, and the EEPROM circuit in the display panel memorizes and stores the R color maximum threshold value so as to ensure that the lamps call data after being powered off and restarted. When the lamp RGBW superposed color emits light and runs out of different pattern effects, the RGBW superposed color white light of the patterns is balanced, and the deviation is not large.
The specific implementation method of the patent is
(1) The RGBW of the multi-lens point control imaging effect lamp is set to be full bright (namely channel level of each color is set to be 255), the focusing stroke is set to be maximum (namely each LED is in an imaging state), then a technician covers a new piece of white printing paper on a lamp lens disc, and observes the RGBW superposition color of each LED penetrating through the printing paper.
(2) After confirming that the LEDs with certain bit numbers need zero adjustment data, the submenus such as the submenus LED1 lamp bead R, LED2 lamp bead R, LED3 lamp bead R and the like in the display panel 'zero adjustment' menu are searched for the LED submenus with corresponding bit numbers. The LED bit number can be quickly found, for example, by setting R of an LED to 0 in the submenu (default value is FFFF), the RGBW overlay color of that LED can be changed obviously. By analogy, the LED position number required to be adjusted can be found.
(3) And setting proper dimming data (namely determining the R maximum channel level threshold) through a DOWN key or an UP key, and observing the change of the color of the white light superposed on the corresponding position number LED in real time. Since the R color channel level of each LED is 0-255 and the R color also has a trim channel level of 0-255, we convert it to 16-bit binary data FFFF (FFFF is the default maximum), which allows the R max channel level threshold of each LED to be adjusted in more detail.
For example: as shown in fig. 7, the maximum threshold R of a certain LED is reduced from FFFF (65535 decimal), to FD80 (64896 decimal), i.e., from 64896 to 65535 invalid data, and even if the console transmits channel level data varying from 0 to 65535 through the DMX512 signal line, the display panel receives only the channel level data of 0 to 64896 or the display panel transmits only the channel level data of 0 to 64896 through the RS485 signal line.
(4) The data is stored through the ENTER key, and the EEPROM circuit of the display panel memorizes and stores the data.
2. White light balance data when the RGBW of each LED is overlapped with colors is temporarily shielded through a 'functional channel' of the console, so that the lamp can output the maximum brightness, and scene application with high illuminance requirement is met.
Before each LED lamp leaves a factory, white light balance data during RGBW superposition is set, and the LED lamp can use a pattern effect function and a WASH function with zooming (namely the LED is not in an imaging effect). In the pattern effect function we have suitably dimmed the R color of each LED individually in the luminaire. Therefore, when the individual lamps are all bright in RGBW, the overall light spots of the lamps have two types of white light blue or white light pink. And their illuminance will also vary, especially in the minimum angle of light extraction. At this time, the display panel of the lamp detects channel level data of the pattern channel and the function channel sent by the console, and judges whether the maximum brightness is output. Three cases are illustrated, specifically as follows:
(1) when the pattern channel value is 8-255, the lamp switches the pattern effect function, and the lamp takes the data of white light balance when the RGBW stored by the EEPROM circuit is superposed as the reference.
(2) When the pattern channel value is 0-7, the lamp is switched to have a focusing WASH effect, and the lamp still takes the data of white light balance when the RGBW stored by the EEPROM circuit is superposed as the reference.
(3) When the WASH function with zoom is used, and the luminaire is required to output maximum brightness. When the "function channel" of the console is set to 105, and stays for 5 seconds, the lamp can temporarily shield the data of white light balance when the RGBW is superposed. That is, the lamp is set not to limit the maximum threshold of the R color, and the maximum channel level data of the R color in the DMX512 buffer data is received, and the EEPROM circuit in the display panel does not store the maximum channel level data of the R color.
3. The PN node of the R color has a large natural attenuation phenomenon along with the temperature rise, and the display panel temporarily shields white light balance data when the RGBW of each LED superposes colors according to the temperature fed back by the thermistor, and performs attenuation compensation on the R color so as to meet the application of scenes used in a high-temperature environment.
When the temperature of the LED rises due to long-time lighting, the chip with the color of R is sensitive to the temperature, and a large natural attenuation phenomenon occurs. Before each LED lamp leaves a factory, white light balance data of each LED in the process of superposing colors by RGBW are set. For example, the 1 st lamp bead R is set as FFFF, the 8 th lamp bead R is set as FD80, the 11 th lamp bead R is set as FC10, and the 18 th lamp bead R is set as FA 30. Since the maximum value of the R color of each LED is different, when the R color is attenuated due to temperature rise, the RGBW color-stacking inconsistency is aggravated. At the moment, the display panel temporarily shields white light balance data when the RGBW of each LED superposes colors according to the temperature fed back by the thermistor, and carries out attenuation compensation on the R color.
When the feedback temperature of the current display panel is 45 degrees, the heat radiation fan of the LED lamp starts to rotate, and the rotation voltage of the fan is increased along with the rise of the feedback temperature. When the feedback temperature of the display panel is 60-65 ℃, the display panel temporarily shields the white light balance data when the RGBW superposition color of each LED, and performs attenuation compensation on the R color. When the feedback temperature of the display panel is lower than 60 ℃, the display panel can restore the white light balance data of the RGBW superposed color of each LED. When the feedback temperature of the display panel is 75 degrees, the display panel sends a power reduction command through the RS485, and the MCU for controlling the LEDs properly reduces the output of the PWM duty ratio according to the command to maintain the heat balance of the lamp.
4. When a certain desk lamp is used for a long time after sale and the light attenuation or the replacement part damages the LED, an after-sale technician needs to readjust the RGBW superposition color of each LED through the display panel so as to meet the scene application of after-sale lamp maintenance.
Since the LED lamp is used for a long time after leaving the factory, the aging or "light decay" of each LED in the lamp is different, which may cause deviation of white light balance data in the original RGBW color superimposition. In order to facilitate the operation of an after-sales technician, the submenu of 'all R maximum values' and the submenu of 'all R views' are particularly added in the menu of 'zero adjustment' of the display panel.
If the "all R max" function is used, the lamp can output maximum brightness and the EEPROM circuitry in the display panel will store these maximum threshold values.
If the function of 'checking all R' is used, the lamp can display the current threshold values of all R in the interface of the display panel, which is beneficial to big data statistics of the lamp and is also beneficial to an after-sales technician to quickly know the data originally or currently set by the lamp.
If the function of 'factory setting restoration' is used, the lamp can restore the white light balance data in the RGBW superposed color set before factory.
