Preferably, the intelligent lamp is provided with a processor and a memory, the memory stores a computer program, and the processor implements the brightness and color temperature adjusting method of the intelligent lamp by executing the computer program.
The embodiment of the intelligent lamp and the brightness and color temperature adjusting method thereof comprises the following steps:
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, and 23, and the main controller 16 can control the light-emitting brightness and color temperature of the plurality of LED light-emitting chips 21, 22, and 23, for example, adjust the voltage or current applied to each LED light-emitting chip 21, 22, and 23, so as to change the light-emitting brightness and color temperature of each LED light-emitting chip 21, 22, and 23.
The intelligent lamp 15 is further provided with a brightness sensor 17 and a color temperature sensor 18, the brightness sensor 17 collects brightness of ambient light in an area where the intelligent lamp 15 is located, the collected data are sent to the main controller 16, and the color temperature sensor 18 collects data of color temperature values of the ambient light in 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 lamp 15, so that the light brightness sensor 17 and the color temperature sensor 18 actually collect the light brightness and the color temperature of the light emitted by the LED light emitting chip of the intelligent lamp 15.
In order to realize the control of the intelligent lamp 15, the intelligent lamp 15 performs wireless communication with the cloud server 11 and the intelligent terminal 12, for example, wireless communication modules such as a WIFI module and a bluetooth module are arranged in the intelligent lamp 15, and the intelligent lamp 15 performs wireless communication with the cloud server 11 and the intelligent terminal 12 through the wireless communication modules. For example, a user may send a control signal to the main controller 16 of the smart lamp 15 through the smart terminal 12 such as a smart phone or a tablet computer, for example, send a control signal including a target brightness value and a target color temperature value, and the smart lamp 15 adjusts the luminance of the LED light emitting chip to the target brightness value and adjusts the color temperature of the LED chip to the target color temperature value.
In order to detect whether the brightness and the color temperature of the LED chip reach the target brightness value and the target color temperature value, the main controller 16 obtains the data collected by the brightness sensor 17 and the color temperature sensor 18, and adjusts the brightness and the color temperature of the LED chip according to the data collected by the brightness 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 changes suddenly, 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 the intelligent lamp is not adjusted in place at once, so that the user can be prevented from feeling discomfort. The process of changing the brightness and the color temperature of the intelligent lamp 15 can be diversified, 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 can be adjusted according to the brightness adjusting change curve, and the color temperature change of the intelligent lamp 15 can be adjusted according to the color temperature adjusting change curve.
Preferably, the user sets a plurality of brightness and color temperature adjustment schemes in advance, and stores the plurality of brightness and color temperature adjustment schemes in the cloud server 11, that is, the cloud server 11 stores a plurality of brightness adjustment variation curves and a plurality of color temperature adjustment variation 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 may be a numerical range; similarly, each color temperature adjustment 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 adjustment change curve may be a numerical range.
Further, the same target brightness value and actual brightness value may correspond to more than two brightness adjustment variation curves, and the same target color temperature value and actual color temperature value may correspond to more than two color temperature adjustment variation curves. The user can select one of the brightness adjustment change curve and the color temperature adjustment change curve from a plurality of preset brightness adjustment change curves and color temperature adjustment change curves as a scheme for adjusting brightness and color temperature currently. After the 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 process of adjusting the brightness and the color temperature of the intelligent lamp 15 is described below with reference to fig. 2. First, step S1 is executed to obtain a target brightness value and a target color temperature value set by the 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 luminaire 15 through the intelligent terminal 12.
Then, the intelligent lamp 15 executes 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 to be adjusted, 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 a color temperature value that needs to be adjusted, that is, after the intelligent lamp 15 receives a target color temperature value, color temperature data of light rays of the surrounding environment is collected through the color temperature sensor 18, and the color temperature data is the first actual color temperature value.
Then, the smart lamp 15 sends the target brightness value, the target color temperature value, and the data of the first actual brightness value and the first actual color temperature value to the cloud server 11, and obtains a brightness adjustment variation curve and a color temperature adjustment variation curve from the cloud server 11. For example, the cloud server 11 obtains a matched brightness adjustment variation curve according to the target brightness value and the first actual brightness value, if there are multiple brightness adjustment variation curves corresponding to the target brightness value and the first actual brightness value, the multiple brightness adjustment variation curves may be fed back to the intelligent terminal 12, and a user selects one of the multiple brightness adjustment variation curves as a set brightness adjustment variation 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 the brightness and the color temperature of the intelligent lamp 15, the brightness value and the color temperature value of the surrounding environment of the intelligent lamp 15 are obtained in real time in the process of adjusting the brightness and the color temperature, and the brightness value and the color temperature value obtained in real time are the second actual brightness value and the second actual color temperature value. Therefore, the intelligent luminaire 15 executes step S4 to obtain the second actual brightness value and the second actual color temperature value in real time through the light brightness sensor 17 and the color temperature sensor 18.
Then, step S5 is executed to calculate the brightness value and the color temperature value of the intelligent luminaire. In order to enable the actual brightness value of the intelligent lamp to be closest to the target brightness value and the actual color temperature value of the intelligent lamp to be closest to the target color temperature value, and simultaneously filter external interference such as personnel walking, curtain opening and the like, 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 for calculation.
Specifically, the calculation formula of the PID control algorithm is as follows:
in formula 1, u (t) is the output signal of PID control, KpIs a proportional gain coefficient, TtTo integrate the time constant, TDIs a differential time constant, e (t) is a given value r (t) is the difference with the measured value。
When the PID control algorithm is applied to the control of the intelligent lamp, u (t) can be set as the output of the intelligent lamp, for example, the output values 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, the measured values are the second actual brightness value and the second actual color temperature value obtained in real time, and Kp、TtAnd TDIt is a control constant that is set in advance according to the actual environment.
Further, according to the output regulation mode of the intelligent lamp, a PID incremental algorithm can be selected to realize PID control, for example, the following formula is used for control:
Δ u (k) ═ u (k) — u (k-1) (formula 2)
Wherein u (k) is the output value at the current time, that is, the brightness value or the color temperature value at the current time, and u (k-1) is the output value at the previous time, that is, the brightness value or the color temperature value at the previous time, and the brightness value or the color temperature value of the intelligent lamp 15 is adjusted according to the calculated difference Δ u (k), that is, the output brightness or the color temperature of the intelligent lamp 15 is determined according to Δ u (k), so that the brightness and the color temperature of the intelligent lamp 15 gradually approach the target brightness value and the target color temperature value through the adjustment mode.
According to the embodiment, the stability of the whole intelligent lamp 15 in adjusting the brightness value and the color temperature value is enhanced by introducing the PID control algorithm, the adjusting process of the whole intelligent lamp 15 is in closed control, errors can be effectively reduced, external interference is reduced, and finally the state of ambient light reaches a set expected state.
Next, step S6 is executed to adjust the brightness and color temperature of the smart 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 ambient environment of the intelligent lamp is obtained through the brightness sensor 17, the color temperature value of the ambient environment is obtained through the color temperature sensor 18, whether the brightness value of the ambient environment reaches the target brightness value or not is judged, whether the color temperature value of the ambient environment reaches the target color temperature value or not is judged, if yes, the adjustment of the brightness and the color temperature of the intelligent lamp is stopped, otherwise, step S4 is executed, the second actual brightness value and the second actual color temperature value are continuously obtained, and the actual brightness value and the actual color temperature value are continuously adjusted until the target brightness value and the target color temperature value are reached.
In this embodiment, the main controller 16 may include a Processor and a memory, and the Processor may be a Central Processing Unit (CPU), other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, a discrete hardware component, and the like. The general-purpose processor may be a microprocessor or the processor may be any conventional processor or the like, the processor being the control center of the terminal device and connecting the various parts of the entire terminal device using various interfaces and lines.
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 mobile phone, and the like.

In addition, the actual brightness value and the color temperature value are continuously obtained in the adjusting process and are adjusted according to the PID control algorithm, so that sudden changes of the brightness and the color temperature of the intelligent lamp can be avoided, and the user is prevented from feeling uncomfortable.
