Preferably, the intelligent lamp is provided with a processor and a memory, wherein a computer program is stored in the memory, and the processor realizes the brightness color temperature adjusting method of the intelligent lamp by executing the computer program.
Intelligent lamp and brightness and color temperature adjusting method embodiment thereof:
referring to fig. 1, the intelligent lamp 15 of the present embodiment has a main controller 16, and is provided with a plurality of LED light emitting chips 21, 22, 23, and the main controller 16 can control the light emitting luminance and color temperature of the plurality of LED light emitting chips 21, 22, 23, for example, adjust the voltage or current applied to each LED light emitting chip 21, 22, 23, thereby changing the light emitting luminance and color temperature of each LED light emitting chip 21, 22, 23.
The intelligent lamp 15 is also internally provided with a brightness sensor 17 and a color temperature sensor 18, wherein the brightness sensor 17 collects the brightness of the ambient light of the area where the intelligent lamp 15 is located and sends the collected data to the main controller 16, and the color temperature sensor 18 collects the data of the color temperature value of the ambient light of the area where the intelligent lamp 15 is located and sends the collected data to the main controller 16. Preferably, the light brightness sensor 17 and the color temperature sensor 18 are disposed on the housing of the intelligent lighting fixture 15, such that the light brightness sensor 17 and the color temperature sensor 18 are actually used for collecting the light brightness and the color temperature of the light emitted by the LED light emitting chip of the intelligent lighting fixture 15.
In order to realize the control to intelligent lamps and lanterns 15, intelligent lamps and lanterns 15 carry out wireless communication with high in the clouds server 11 and intelligent terminal 12, for example set up wireless communication module such as WIFI module, bluetooth module in the intelligent lamps and lanterns 15, intelligent lamps and lanterns 15 carry out wireless communication with high in the clouds server 11 and intelligent terminal 12 through wireless communication module. For example, the user may send a control signal, such as a control signal including a target luminance value and a target color temperature value, to the main controller 16 of the smart luminaire 15 through the smart terminal 12, such as a smart phone, a tablet computer, etc., and the smart luminaire 15 adjusts the light emitting luminance of the LED light emitting chip to the target luminance value and adjusts the color temperature of the LED chip to the target color temperature value.
In order to detect whether the light emission luminance and color temperature of the LED chip have reached the target luminance value and the target color temperature value, the main controller 16 acquires data collected by the luminance sensor 17 and the color temperature sensor 18, and adjusts the luminance and the color temperature of the LED light emission chip according to the data collected by the luminance sensor 17 and the color temperature sensor 18.
In the process of adjusting the brightness and the color temperature of the LED light-emitting chip, if the brightness or the color temperature of the intelligent lamp 15 suddenly changes, discomfort can be caused to a user, in order to avoid discomfort to the user, the brightness and the color temperature of the intelligent lamp 15 are gradually adjusted and are not adjusted in place at one time, so that the discomfort felt by the user can be avoided. The process of changing the light-emitting brightness and the color temperature of the intelligent lamp 15 can be various, and a user can set an individualized brightness and color temperature adjusting scheme according to own preference, namely, an individualized brightness adjusting change curve and an individualized color temperature adjusting change curve are set, the brightness change of the intelligent lamp 15 is adjusted according to the brightness adjusting change curve, and the color temperature change of the intelligent lamp 15 is adjusted according to the color temperature adjusting change curve.
Preferably, the user presets a plurality of brightness and color temperature adjustment schemes, and stores the brightness and color temperature adjustment schemes in the cloud server 11, that is, the cloud server 11 stores a plurality of brightness adjustment change curves and a plurality of color temperature adjustment change curves. Preferably, each brightness adjustment change curve corresponds to a target brightness value and an actual brightness value, and the target brightness value and the actual brightness value corresponding to the brightness adjustment change curve can be a numerical range; similarly, each color temperature adjusting change curve corresponds to a target color temperature value and an actual color temperature value, and the target color temperature value and the actual color temperature value corresponding to the color temperature adjusting change curve can be a numerical range.
Further, for the same target luminance value and actual luminance value, two or more luminance adjustment change curves may be corresponding, and for the same target color temperature value and actual color temperature value, two or more color temperature adjustment change curves may be corresponding. The user can select one of the preset brightness adjusting change curve and the preset color temperature adjusting change curve from the preset brightness adjusting change curve and the preset color temperature adjusting change curve, and the one of the preset brightness adjusting change curve and the preset color temperature adjusting change curve is used as a scheme for adjusting the brightness and the color temperature. When a user selects a brightness adjustment change curve and a color temperature adjustment change curve, the cloud server 11 sends the selected brightness adjustment change curve and color temperature adjustment change curve to the main controller 16 of the intelligent lamp 15, and the main controller 16 adjusts the brightness of the intelligent lamp 15 according to the brightness adjustment change curve and adjusts the color temperature of the intelligent lamp 15 according to the color temperature adjustment change curve.
The following describes the process of adjusting the brightness and color temperature of the intelligent luminaire 15 in connection with fig. 2. First, step S1 is performed to obtain a target brightness value and a target color temperature value set by a user, where the target brightness value and the target color temperature value are the brightness value and the color temperature value sent by the user to the main controller 16 of the intelligent lamp 15 through the intelligent terminal 12.
Then, the intelligent lamp 15 performs step S2 to obtain a first actual brightness value and a first actual color temperature value, where the first actual brightness value is a brightness value when the intelligent lamp 15 receives the brightness adjustment required, that is, after the intelligent lamp 15 receives the target brightness value, the brightness sensor 17 collects brightness data of light of the surrounding environment, and the brightness data is the first actual brightness value. The first actual color temperature value is a color temperature value when the intelligent lamp 15 receives the color temperature adjustment, that is, after the intelligent lamp 15 receives the target color temperature value, the color temperature sensor 18 collects the color temperature data of the light of the surrounding environment, and the color temperature data is the first actual color temperature value.
Next, the intelligent luminaire 15 transmits the target luminance value, the target color temperature value, and the data of the first actual luminance value, the first actual color temperature value to the cloud server 11, and acquires the luminance adjustment change curve and the color temperature adjustment change curve from the cloud server 11. For example, the cloud server 11 obtains a matched brightness adjustment change curve according to the target brightness value and the first actual brightness value, if there are multiple brightness adjustment change curves corresponding to the target brightness value and the first actual brightness value, the multiple brightness adjustment change curves may be fed back to the intelligent terminal 12, and the user selects one of the multiple brightness adjustment change curves as the set brightness adjustment change curve. Similarly, the cloud server 11 obtains a matched color temperature adjustment change curve according to the target color temperature value and the first actual color temperature value, if there are multiple color temperature adjustment change curves corresponding to the target color temperature value and the first actual color temperature value, the multiple color temperature adjustment change curves can be fed back to the intelligent terminal 12, and a user selects one of the multiple color temperature adjustment change curves as a set color temperature adjustment change curve.
The intelligent lamp 15 receives the brightness adjustment change curve and the color temperature adjustment change curve, and adjusts the brightness and the color temperature of the intelligent lamp according to the obtained brightness adjustment change curve and the obtained color temperature adjustment change curve. In order to avoid abrupt change of brightness and color temperature of the intelligent lamp 15, in the process of adjusting the brightness and the color temperature, the brightness value and the color temperature value of the surrounding environment of the intelligent lamp 15 are obtained in real time, and the obtained brightness value and color temperature value in real time are the second actual brightness value and the second actual color temperature value. Therefore, the intelligent luminaire 15 performs step S4 to obtain the second actual brightness value and the second actual color temperature value in real time through the brightness sensor 17 and the color temperature sensor 18.
Then, step S5 is performed to calculate the brightness value and the color temperature value of the intelligent lamp. In order to make the actual brightness value of the intelligent lamp closest to the target brightness value, and the actual color temperature value of the intelligent lamp closest to the target color temperature value, and simultaneously filter external interference, such as personnel walking, curtain pulling, etc., the embodiment calculates the brightness value and the color temperature value of the intelligent lamp 15 through a closed-loop control system, and specifically, introduces a PID control algorithm to calculate.
Specifically, the calculation formula of the PID control algorithm is as follows:
in the formula 1, u (t) is an output signal of PID control, K p Is a proportional gain coefficient, T t Is an integral time constant, T D E (t) is the given value r (t) is the difference from the measured value, which is the differential time constant.
The PID control algorithm is applied to the control of the intelligent lamp, u (t) can be set as the output value of the intelligent lamp, for example, the output value of the brightness value and the color temperature value of the intelligent lamp, the given value r (t) is set as the target brightness value and the target color temperature value, and the measured value is the second actual brightness value obtained in real timeA second actual color temperature value, K p 、T t And T is D The control constant is preset according to the actual environment.
Further, depending on the manner in which the intelligent light fixture output is adjusted, PID control may be implemented using a PID incremental algorithm, for example, using the following formula:
deltau (k) =u (k) -u (k-1) (formula 2)
Wherein u (k) is the output value of the current moment, i.e. the brightness value or the color temperature value of the current moment, u (k-1) is the output value of the previous moment, i.e. the brightness value or the color temperature value of the previous moment, and the brightness value or the color temperature value of the intelligent lamp 15 is regulated according to the calculated difference value delta u (k), i.e. the output brightness or the color temperature of the intelligent lamp 15 is determined according to the delta u (k), and the brightness and the color temperature of the intelligent lamp 15 gradually approach to the target brightness value and the target color temperature value by adopting the regulation mode.
According to the embodiment, the PID control algorithm is introduced, so that the stability of the whole intelligent lamp 15 in adjusting the brightness value and the color temperature value is enhanced, the whole intelligent lamp 15 is in closed control in the adjusting process, errors can be effectively reduced, the external interference is reduced, and finally the state of the ambient light reaches the set expected state.
Next, step S6 is performed to adjust the brightness and color temperature of the intelligent lamp 15 according to the calculated brightness value and color temperature value, for example, the main controller 16 adjusts the voltage and current applied to each LED light emitting chip 21, 22, 23. Finally, step S7 is executed, the brightness value of the surrounding environment of the intelligent lamp is obtained through the brightness sensor 17, the color temperature value of the surrounding environment is obtained through the color temperature sensor 18, whether the brightness value of the surrounding environment reaches the target brightness value or not is judged, if so, the adjustment of the brightness and the color temperature of the intelligent lamp is stopped, otherwise, step S4 is executed again, the second actual brightness value and the second actual color temperature value are continuously obtained, and the adjustment of the actual brightness value and the actual color temperature value is continuously carried out until the target brightness value and the target color temperature value are reached.
In this embodiment, the main controller 16 may include a processor, which may be a central processing unit (Central Processing Unit, CPU), other general purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), off-the-shelf programmable gate arrays (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, the processor being a control center of the terminal device, and the various interfaces and lines being used to connect the various parts of the overall terminal device.
The memory may be used to store computer programs and/or modules, and the processor may implement various functions of the terminal device by running or executing the computer programs and/or modules stored in the memory, and invoking data stored in the memory. The memory may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function, and the like; the storage data area may store data created according to the use of the cellular phone, etc. In addition, the memory may include high-speed random access memory, and may also include non-volatile memory, such as a hard disk, memory, plug-in hard disk, smart Media Card (SMC), secure Digital (SD) Card, flash Card (Flash Card), at least one disk storage device, flash memory device, or other volatile solid-state storage device.
Because the intelligent lamp adjusts the brightness and the color temperature according to the preset brightness adjusting change curve and the preset color temperature adjusting change curve in the process of adjusting the brightness and the color temperature, the personalized requirements of users are met. In addition, in the adjusting process, the actual brightness value and the actual color temperature value are continuously obtained, and the brightness value and the actual color temperature value are adjusted according to the PID control algorithm, so that abrupt changes of the brightness and the color temperature of the intelligent lamp can be avoided, and discomfort felt by a user is avoided.
