Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the invention. For better illustration of the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Example 1
As shown in fig. 1, the present embodiment provides a method for calibrating dimming data of a lamp, including the following steps:
and the lamp receives the calibration data directly sent by the RDM controller and the dimming data sent by the console, calculates a calibration value according to the calibration data sent by the RDM controller, and then calibrates the dimming data of the console received later by using the calibration value.
The conventional method for changing the calibration value of the lamp requires the lamp to be provided with a control panel capable of inputting commands through keys, and is not suitable for the lamp without the control panel. According to the method provided by the embodiment, the RDM controller is utilized to directly send the calibration data to the lamp, the lamp is not required to be provided with a control panel, the calibration value of the lamp is not required to be modified by combining with a console, and the calibration value of the lamp is directly modified through the RDM controller.
It should be noted that the RDM controller is manufactured based on RDM protocol (Remote Device Management ) and is commercially available, such as CY-R02 model machine of red flame light limited, guangzhou. In this embodiment, the RDM controller and the console are integrated, and in the process of controlling the lamp by the console, the dimming parameters of the lamp can be calibrated at any time.
In this embodiment, the dimming data includes at least one of brightness, color temperature, color or color rendering index of the lamp light. Therefore, the calibration of the brightness, the color temperature, the color or the color rendering index of the lamp is realized, the uniform light effect of a plurality of lamps is achieved, and the deviation is lower.
In this embodiment, the calibration data and the dimming data are in DMX format. In other embodiments, the calibration data and the dimming data may be in the same format or different formats, or may be in a format that can be received by a lamp other than the DMX format.
In this embodiment, the lamp calibrates the dimming data sent by the console in real time according to the received calibration data, and displays the calibrated light effect. The calibrator can intuitively pre-observe the corrected effect, and adjust the calibration data while observing until reaching the satisfactory effect, so that the calibrator can calibrate conveniently, and the operation is convenient and quick.
In this embodiment, after receiving the calibration setting command sent by the RDM controller, the lamp updates the calibration value stored previously. Before receiving the calibration setting command sent by the RDM controller, the lamp calibrates the dimming data sent by the console in real time only according to the calibration data sent by the RDM controller, and displays the calibrated light effect, but does not save the calibrated light effect and covers the previous calibration value.
In this embodiment, the calculating the calibration value according to the calibration data specifically includes: the calibration value is obtained by dividing the calibration data by the maximum value of the lamp dimming data. In general, when a signal format of DMX format is adopted, the maximum value is 255.
In this embodiment, the calibrating the dimming data received later according to the calibration value specifically includes: the dimming data received later is multiplied by the calibration value.
In this embodiment, the RDM controller is connected to a plurality of the lamps, and performs broadcast calibration on dimming data of the plurality of the lamps. The RDM controller can control a plurality of lamps, and the efficiency is higher.
In this embodiment, the RDM controller has a data reading unit for reading the calibration value saved by the luminaire. The old calibration value stored before the lamp is read, so that a calibrator can more clearly calibrate the lamp, and the lamp is convenient to calibrate.
In this embodiment, the data reading unit performs a reading operation each time the RDM controller is started. The automatic reading is more convenient without manual operation of a calibrator.
In this embodiment, the RDM controller has an input unit for a user to input calibration data. The calibrator can input calibration data through an input unit, and optionally, the input unit can be a touch screen, can also be a key, and is preferably an up-down key or a left-right key, so that the calibration data is gradually increased or decreased.
In this embodiment, the RDM controller has a display unit that visually presents data. The calibrator can directly see the input calibration data value change through the display unit of the RDM controller, and can also see the old calibration value of the lamp read back by the RDM controller.
Specifically, an RDM command protocol is defined in the RDM controller as a calibration function, so that the RDM controller can read old calibration data of the lamp and receive new calibration data input by a user, and then a program unit capable of receiving the RDM data is added in the lamp. When the lamp works, the lamp processes the data sent by the RDM controller, firstly feeds back a response, and sends the old calibration data value stored in the lamp back to the RDM controller for display, then receives the new calibration data input by the RDM controller by a user, after receiving a calibration setting command sent by the console through the RDM controller, the lamp calculates a calibration value according to the new calibration data, and then processes the dimming data received later according to the calibration value.
As shown in fig. 1, taking the calibration of the brightness of a lamp as an example, the range of the DMX value of the dimming channel of a certain lamp is 0 to 255, that is, the maximum DMX value of the lamp is 255, the brightness of the corresponding lamp is 0 to 100%, the brightness of the lamp is 0 when the DMX value of the dimming channel of the lamp is 0, the brightness of the lamp is 100% when the DMX value of the dimming channel of the lamp is 255, and the brightness of the lamp is about 50% when we adjust the DMX value of the dimming channel to 127.
The RDM controller sends calibration data to the lamp, the lamp receives the calibration data for storage, after receiving a calibration setting command sent by the console through the RDM controller, the calibration data (127) is divided by 255 to obtain a calibration value (about 0.498), then the DMX value received by the dimming channel of the lamp is multiplied by the calibration value, namely when the DMX value received by the dimming channel of the lamp is 255, the actual DMX value is 127, the brightness is changed from 100% to about 50%, and the same brightness can be kept among different lamps by changing the calibration values of the dimming channels of different lamps, so that the calibration of the brightness function of the lamp is realized.
A calibration setup function is customized in advance based on the RDM protocol. An example of a custom calibration setup function design based on the RDM protocol is shown in fig. 2. In fig. 2, port ID represents Port ID; response Type represents the form of the Response; message Count represents an information Count range; sub-development represents the number of components of the device; CC is an abbreviation of Command Class, indicating a Command type, SET_COMMAND indicates a SET Command, SET_COMMAND_RESPONSE indicates a reply SET Command; PID is abbreviation of Parameter ID, which indicates Parameter ID, CALIBRATION is self-defined PID; PD is an abbreviation for Parameter ID, representing Parameter data, parameter 1 representing that calibration settings are to be made, and Parameter Not Present representing that there is no value; PDL is an abbreviation of Parameter Data Length, which means the length of parameter data, typically ranging from 0 to 255, and in this embodiment, the length of PDL parameter data is 5%.
