技术领域Technical Field
本发明涉及LED灯领域，尤其涉及一种摄影灯及控制方法。The present invention relates to the field of LED lamps, and in particular to a photographic lamp and a control method thereof.
背景技术Background technique
目前市面上出现各种各样的LED摄影灯，基本可以实现色温，亮度可调。但是普遍会存在一个问题，色温与实际偏差大，造成这种偏差的原因在于他们的LED灯是一个开环控制系统。There are various LED photography lights on the market, which can basically achieve color temperature and brightness adjustment. However, there is a common problem that the color temperature deviates greatly from the actual color temperature. The reason for this deviation is that their LED lights are an open-loop control system.
所谓开环控制系统是输入信号不受输出信号影响的控制系统，也就是不将控制的结果反馈回来影响当前控制系统。与之相对的是闭环控制系统，闭环控制系统具体内容是指：把控制系统输出量的一部分或全部，通过一定方法和装置反送回系统的输入端，然后将反馈信息与原输入进行比较，再将比较的结果施加于系统进行控制，避免系统偏离预定目标。The so-called open-loop control system is a control system in which the input signal is not affected by the output signal, that is, the control result is not fed back to affect the current control system. In contrast, a closed-loop control system refers to: part or all of the control system output is fed back to the input end of the system through certain methods and devices, and then the feedback information is compared with the original input, and the comparison result is applied to the system for control to prevent the system from deviating from the predetermined target.
闭环系统利用的是负反馈，由信号正向通路和反馈通路构成闭合回路的自动控制系统，又称反馈控制系统。The closed-loop system utilizes negative feedback. It is an automatic control system that consists of a closed loop consisting of a signal forward path and a feedback path, also known as a feedback control system.
因为市面上的可调节的LED是采用开环控制系统，也就没有对输出的光进行实时反馈，当LED灯珠来料有差异(波长，发光强度等)或者LED灯珠的温升都会带来误差，导致实际输出的光与理论值有较大偏差，偏离预定目标，体现在色温精度不够或者白光偏色等方面。Because the adjustable LEDs on the market use an open-loop control system, there is no real-time feedback on the output light. When there are differences in the incoming LED lamp beads (wavelength, luminous intensity, etc.) or the temperature rise of the LED lamp beads, errors will occur, resulting in a large deviation between the actual output light and the theoretical value, deviating from the predetermined target, which is reflected in insufficient color temperature accuracy or white light color cast.

The RGB sensor or the tristimulus value XYZ sensor detects RGB parameters or tristimulus value XYZ parameters of light and feeds back the RGB parameters or tristimulus value XYZ parameters of light to the control module 1.
当然，所述第一传感器模块2与所述第二传感器模块3也可以是检测光的其他参数的传感器，比如检测光的亮度的光敏传感器等。Of course, the first sensor module 2 and the second sensor module 3 may also be sensors for detecting other parameters of light, such as photosensors for detecting brightness of light.
在本发明实施例中，所述控制模块1包括：主控单元11以及信号转换单元12，所述模拟灯组5通过第一恒流源模块7耦合到所述信号转换单元12，所述实际输出灯组4通过第二恒流源模块6耦合到所述信号转换单元12。所述信号转换单元12将所述主控单元11的数字信号转换为模拟信号以使所述第一恒流源模块7与所述第二恒流源模块6驱动所述模拟灯组5与实际输出灯组4输出。In the embodiment of the present invention, the control module 1 includes: a main control unit 11 and a signal conversion unit 12, the simulated light group 5 is coupled to the signal conversion unit 12 through the first constant current source module 7, and the actual output light group 4 is coupled to the signal conversion unit 12 through the second constant current source module 6. The signal conversion unit 12 converts the digital signal of the main control unit 11 into an analog signal so that the first constant current source module 7 and the second constant current source module 6 drive the simulated light group 5 and the actual output light group 4 to output.
所述主控单元11由主控芯片及外围电路构成的微控制单元，是整个摄影灯系统的控制枢纽，由所述主控单元11发出指令控制各类模块，再由各类模块控制其子模块。所述主控单元11输出PWM控制信号。The main control unit 11 is a microcontroller composed of a main control chip and peripheral circuits, and is the control hub of the entire photography light system. The main control unit 11 issues instructions to control various modules, and various modules then control their submodules. The main control unit 11 outputs a PWM control signal.
所述信号转换单元12为PWM转DAC元件，可将主控单元11输出的PWM数字信号转换为电压的模拟信号，以供所述第一恒流源模块7与所述第二恒流源模块6使用。The signal conversion unit 12 is a PWM to DAC element, which can convert the PWM digital signal output by the main control unit 11 into a voltage analog signal for use by the first constant current source module 7 and the second constant current source module 6 .
在本发明实施例中，所述实际输出灯组4及所述模拟灯组5由基板及成组分布在所述基板上的不同颜色的LED灯珠组成。所述每组不同颜色的LED灯珠为所述输出灯组与所述模拟灯组5的发光单元，通过调节所述每组不同颜色的LED灯珠的参数来调节所述摄影灯输出光的参数。In the embodiment of the present invention, the actual output light group 4 and the simulation light group 5 are composed of a substrate and LED lamp beads of different colors distributed in groups on the substrate. Each group of LED lamp beads of different colors is a light-emitting unit of the output light group and the simulation light group 5, and the parameters of the output light of the photography light are adjusted by adjusting the parameters of each group of LED lamp beads of different colors.
所述每组不同颜色的LED灯珠优选为R（红光）、G（绿光）、B（蓝光）、W（白光）四色LED灯珠。其中，白光LED灯珠为主要的发光灯珠，红光、绿光及蓝光LED灯珠为可调节的混光LED灯珠，混光LED灯珠用以调节所述摄影灯的色温。Each group of LED lamp beads of different colors is preferably a four-color LED lamp bead of R (red light), G (green light), B (blue light), and W (white light). Among them, the white light LED lamp bead is the main light-emitting lamp bead, and the red light, green light and blue light LED lamp beads are adjustable mixed light LED lamp beads, and the mixed light LED lamp beads are used to adjust the color temperature of the photography light.
具体的，在白光LED灯珠的光输出固定时，增大所述红光 LED灯的输出，并增加适量的绿光LED灯珠的输出，可降低所述摄影灯输出光的色温；同样的，在白光LED灯珠的光输出固定时，增大所述蓝光LED灯的输出，并增加适量的绿光LED灯珠的输出，可升高所述摄影灯输出光的色温。Specifically, when the light output of the white light LED lamp beads is fixed, increasing the output of the red light LED lamp and adding an appropriate amount of output of the green light LED lamp beads can reduce the color temperature of the output light of the photography light; similarly, when the light output of the white light LED lamp beads is fixed, increasing the output of the blue light LED lamp and adding an appropriate amount of output of the green light LED lamp beads can increase the color temperature of the output light of the photography light.
另外，所述实际输出灯组4及所述模拟灯组5的发光单元也可以是由双色灯组成，所述双色灯由一低色温灯珠和一高色温灯珠组合，所述低色温灯珠和所述高色温灯珠为LED灯珠。通过调节所述低色温LED灯珠与所述高色温LED灯珠以使所述实际输出灯组4及所述模拟灯组5的色温得到调节，从而调节所述摄影灯的色温。具体为增加所述低色温LED灯珠的输出，可降低所述摄影灯的色温；升高所述高色温LED灯珠的输出，可升高所述摄影灯的色温。In addition, the light emitting units of the actual output light group 4 and the simulation light group 5 can also be composed of two-color lights, which are composed of a low color temperature lamp bead and a high color temperature lamp bead, and the low color temperature lamp bead and the high color temperature lamp bead are LED lamp beads. The color temperature of the actual output light group 4 and the simulation light group 5 can be adjusted by adjusting the low color temperature LED lamp bead and the high color temperature LED lamp bead, thereby adjusting the color temperature of the photography light. Specifically, increasing the output of the low color temperature LED lamp bead can reduce the color temperature of the photography light; increasing the output of the high color temperature LED lamp bead can increase the color temperature of the photography light.
在本发明实施例中，所述实际输出灯组4的LED灯珠数量大于所述模拟灯组5的LED灯数量。所述实际输出灯组4需要对外部摄影环境进行输出，因此需要较多的LED灯珠；所述模拟灯组5用于模拟输出，因此只需要少量的LED灯珠。In the embodiment of the present invention, the number of LED lamp beads in the actual output lamp group 4 is greater than the number of LED lamps in the simulation lamp group 5. The actual output lamp group 4 needs to output the external photographic environment, so it needs more LED lamp beads; the simulation lamp group 5 is used for simulation output, so it only needs a small number of LED lamp beads.
所述实际输出灯组4的基板尺寸也大于所述模拟灯组5的尺寸，所述实际输出灯组4上分布的LED灯的组数也多于所述模拟灯组5上分布的LED灯的组数。The substrate size of the actual output lamp group 4 is also larger than that of the simulated lamp group 5 , and the number of LED lamp groups distributed on the actual output lamp group 4 is also greater than the number of LED lamp groups distributed on the simulated lamp group 5 .
在本发明实施例中，所述实际输出灯组4的输出功率大于所述模拟灯组5的输出功率。拥有更大输出功率的实际输出灯组4使所述摄影灯的输出效果更加明显。所述实际输出灯组4与所述模拟灯组5不共用恒流源模块，输出功率有所不同，由于LED灯珠出厂时存在差异，需要进行校正，把校正数据固化到所述主控单元11中，主控单元11只需要对所述模拟灯组5的输出光进行采集和调整控制就可以使实际输出灯组4保持同步输出。In the embodiment of the present invention, the output power of the actual output light group 4 is greater than the output power of the simulation light group 5. The actual output light group 4 with a larger output power makes the output effect of the photographic light more obvious. The actual output light group 4 and the simulation light group 5 do not share the constant current source module, and the output power is different. Since there are differences in the LED lamp beads when leaving the factory, calibration is required, and the calibration data is solidified in the main control unit 11. The main control unit 11 only needs to collect and adjust the output light of the simulation light group 5 to keep the actual output light group 4 output synchronously.
另外，所述第一恒流源模块7包括：用以驱动所述模拟灯组5上白光LED灯珠的第一白光驱动电路71，用以驱动所述模拟灯组5上红光LED灯珠的第一红光驱动电路72，用以驱动所述模拟灯组5上绿光LED灯珠的第一绿光驱动电路73，以及用以驱动所述模拟灯组5上蓝光LED灯珠的第一蓝光驱动电路74；同时，所述第二恒流源模块6包括：用以驱动所述实际输出灯组4上白光LED灯珠的第二白光驱动电路61，用以驱动所述实际输出灯组4上红光LED灯珠的第二红光驱动电路62，用以驱动所述实际输出灯组4上绿光LED灯珠的第二绿光驱动电路63，以及用以所述实际输出灯组4上蓝光LED灯珠的第二蓝光驱动电路64。In addition, the first constant current source module 7 includes: a first white light driving circuit 71 for driving the white light LED lamp beads on the simulated lamp group 5, a first red light driving circuit 72 for driving the red light LED lamp beads on the simulated lamp group 5, a first green light driving circuit 73 for driving the green light LED lamp beads on the simulated lamp group 5, and a first blue light driving circuit 74 for driving the blue light LED lamp beads on the simulated lamp group 5; at the same time, the second constant current source module 6 includes: a second white light driving circuit 61 for driving the white light LED lamp beads on the actual output lamp group 4, a second red light driving circuit 62 for driving the red light LED lamp beads on the actual output lamp group 4, a second green light driving circuit 63 for driving the green light LED lamp beads on the actual output lamp group 4, and a second blue light driving circuit 64 for driving the blue light LED lamp beads on the actual output lamp group 4.
另外，所述控制模块1、所述模拟灯组5及所述第二传感器模块3集成在一控制盒内，所述第一传感器模块2与所述实际输出灯组4设置在所述控制盒外。In addition, the control module 1, the simulation lamp group 5 and the second sensor module 3 are integrated in a control box, and the first sensor module 2 and the actual output lamp group 4 are arranged outside the control box.
如图3所示，还提出一种摄影灯的控制方法，所述控制方法包括步骤：通过第一传感器模块2获取外部环境的环境光数据；根据外部环境光数据通过模拟灯组5进行模拟输出；通过第二传感器模块3获取所述模拟灯组5模拟输出的模拟输出光数据；根据所述模拟输出光数据调整实际输出光的输出数据控制实际输出灯组4进行输出。通过所述第一传感器模块2获取的外部环境的环境光数据，可做为输入值输入控制模块1中储存，所述控制模块1输出控制信号，控制所述模拟灯组5进行模拟输出，所述第二传感器模块3实时获取所述模拟灯组5模拟输出的模拟输出光数据，将所述模拟输出光数据输入所述控制模块1中分析处理，并输出控制信号，控制调整所述实际输出灯组4的输出光，形成一个闭环反馈系统。As shown in FIG3 , a control method for a photographic light is also proposed, and the control method includes the following steps: obtaining ambient light data of an external environment through a first sensor module 2; performing a simulated output through a simulated light group 5 according to the external ambient light data; obtaining simulated output light data of the simulated output of the simulated light group 5 through a second sensor module 3; adjusting the output data of the actual output light according to the simulated output light data to control the actual output light group 4 to output. The ambient light data of the external environment obtained by the first sensor module 2 can be input into the control module 1 as an input value for storage, and the control module 1 outputs a control signal to control the simulated light group 5 to perform a simulated output, and the second sensor module 3 obtains the simulated output light data of the simulated output of the simulated light group 5 in real time, inputs the simulated output light data into the control module 1 for analysis and processing, and outputs a control signal to control and adjust the output light of the actual output light group 4, forming a closed-loop feedback system.
在本发明实施例中，所述根据外部环境光数据进行模拟输出的步骤包括：通过设置在摄影灯内的一组模拟灯组5进行模拟输出。所述模拟灯组5设置在所述摄影灯内可减少环境光对所述模拟灯组5输出光的影响，而且不会影响所述摄影灯的外观和使用。In the embodiment of the present invention, the step of performing simulation output according to the external ambient light data includes: performing simulation output through a group of simulation light groups 5 arranged in the photographic light. The simulation light group 5 is arranged in the photographic light to reduce the influence of ambient light on the output light of the simulation light group 5, and will not affect the appearance and use of the photographic light.
另外，所述根据外部环境光数据进行模拟输出的步骤也可以是使用计算机进行模拟输出，计算机获取所述第一传感器模块2采集的外部环境光数据模拟出外部环境光的输出。In addition, the step of performing simulation output according to the external ambient light data may also be performed by using a computer, where the computer acquires the external ambient light data collected by the first sensor module 2 to simulate the output of the external ambient light.
在本发明实施例中，所述获取模拟输出的模拟输出光数据的步骤包括：通过设置一模拟传感器用于获取所述模拟灯组5上的模拟输出光数据。所述模拟传感器实时采集所述模拟灯组5上的模拟输出光数据，并将采集到的所述模拟灯组5上的模拟光数据输入所述控制模块1。In the embodiment of the present invention, the step of obtaining the simulated output light data of the simulated output includes: setting an analog sensor for obtaining the simulated output light data on the simulated light group 5. The analog sensor collects the simulated output light data on the simulated light group 5 in real time, and inputs the collected simulated light data on the simulated light group 5 into the control module 1.
另外，如使用计算机对外部环境光进行模拟，可直接得到模拟输出光的数据，将模拟输出光的数据输入所述控制模块1。In addition, if a computer is used to simulate the external ambient light, data of the simulated output light can be directly obtained, and the data of the simulated output light can be input into the control module 1 .
在本发明实施例中，所述根据模拟输出光数据调整实际输出光的输出数据的步骤还包括：在获取模拟输出光数据后，根据摄影灯的实际输出灯组4与所述模拟灯组5的差异数据，调整实际输出光的输出数据。所述控制模块1对模拟输出光数据与环境光数据进行分析对比，由对比得到的结果，对所述实际输出灯组4进行调整。In the embodiment of the present invention, the step of adjusting the output data of the actual output light according to the simulated output light data further includes: after acquiring the simulated output light data, adjusting the output data of the actual output light according to the difference data between the actual output light group 4 of the photographic light and the simulated light group 5. The control module 1 analyzes and compares the simulated output light data with the ambient light data, and adjusts the actual output light group 4 according to the comparison result.
具体的，如所述实际输出灯组4的输出光的输出数据为X，所述模拟灯组5根据环境光数据模拟的输出光的输出数据为X-1，则所述控制模块1调整实际输出光到X－1。Specifically, if the output data of the output light of the actual output lamp group 4 is X, and the output data of the output light simulated by the simulation lamp group 5 according to the ambient light data is X-1, the control module 1 adjusts the actual output light to X-1.
在本发明实施例中，所述控制方法还包括步骤：通过第一恒流源模块7耦合到模拟灯组5进行输出；通过第二恒流源模块6耦合到实际输出灯组4进行输出；所述第一恒流源模块7、第二恒流源模块6共同耦合到同一控制模块1。In an embodiment of the present invention, the control method also includes the steps of: coupling to the simulated lamp group 5 for output through the first constant current source module 7; coupling to the actual output lamp group 4 for output through the second constant current source module 6; the first constant current source module 7 and the second constant current source module 6 are coupled to the same control module 1.
