The timing module is connected to the processing module. The first radio frequency signal module is connected to the processing module. The processing module receives a local time signal through the first radio frequency signal module, and then calibrates the current time of the timing module according to the local time signal to update the current time of the timing module.
[0007] In an embodiment, the processing module receives a local time signal through the first radio frequency signal module and determines whether the difference between the local time signal and the current time of the timing module is within a calibration delay window, wherein the processing module delays calibrating the current time of the timing module according to a preset delay time when the difference between the local time signal and the current time of the timing module is within the calibration delay window.
[0008] In an embodiment, the processing module calibrates the current time of the timing module when the difference between the local time signal and the current time of the timing module is higher than the upper limit of the calibration delay window. The processing module does not calibrate the current time of the timing module when the difference between the local time signal and the current time of the timing module is lower than the lower limit of the calibration delay window.
[0009] In an embodiment, the lighting device further includes a light-emitting module, and the light-emitting module is connected to the processing module. The processing module receives a lighting configuration signal through the first radio frequency signal module and controls the light-emitting module according to the lighting configuration signal.

The information publishing device receives a local time signal. The illumination device includes a processing module, a timing module, and a first radio frequency signal module. The timing module and the first radio frequency signal module are connected to the processing module. The processing module receives the local time signal through the first radio frequency signal module, and then calibrates the current time of the timing module according to the local time signal to update the current time of the timing module.
[0011] In one embodiment, the processing module receives the local time signal through the first radio frequency signal module, and determines whether the difference between the local time signal and the current time of the timing module is within a calibration delay window. The processing module delays the calibration of the current time of the timing module according to a preset delay time when the difference between the local time signal and the current time of the timing module is within the calibration delay window.
[0012] In one embodiment, the processing module calibrates the current time of the timing module when the difference between the local time signal and the current time of the timing module is higher than the upper limit of the calibration delay window. The processing module does not calibrate the current time of the timing module when the difference between the local time signal and the current time of the timing module is lower than the lower limit of the calibration delay window.
[0013] In one embodiment, the illumination device further includes a light emitting module, and the light emitting module is connected to the processing module. The processing module receives an illumination configuration signal through the first radio frequency signal module, and controls the light emitting module according to the illumination configuration signal.
[0014] In one embodiment, the information publishing device includes a global satellite positioning module, a control module, and a second radio frequency signal module. The global satellite positioning module and the second radio frequency signal module are connected to the control module. The global satellite positioning module receives a global satellite positioning signal. The control module generates a local time signal according to the global satellite positioning signal, and transmits the local time signal to the first radio frequency signal module through the second radio frequency signal module.
[0015] In one embodiment, the information publishing device further includes a communication module, and the communication module is connected to the control module. The control module receives the illumination configuration signal through the communication module, and transmits the illumination configuration signal to the first radio frequency signal module.
[0016] As described above, the illumination device and illumination system with a time calibration function according to the embodiments of the present invention may have one or more of the following advantages:
[0017] (1) In an embodiment of the present invention, the lighting device includes a processing module, a timing module, and a first radio frequency signal module. The timing module is connected to the processing module. The first radio frequency signal module is connected to the processing module. The processing module receives a local time signal through the first radio frequency signal module, and then calibrates the current time of the timing module according to the local time signal to update the current time of the timing module. As can be seen from the above, the lighting device has a time synchronization mechanism, so it can effectively perform time synchronization, making the time setting of the lighting device always accurate. Therefore, even after long-term operation, the lighting device will not generate time errors, enabling the lighting device to meet the requirements of practical applications.
[0018] (2) In an embodiment of the present invention, the lighting system not only includes a plurality of lighting devices, but also includes an information publishing device. Each lighting device is integrated with a radio frequency signal module. The information publishing device can manage the time for these lighting devices simultaneously, enabling these lighting devices to effectively achieve time synchronization. In this way, the time settings of these lighting devices can always be accurate. Therefore, the overall cost of the lighting system can be significantly reduced to meet the requirements of different applications.
[0019] (3) In an embodiment of the present invention, the lighting system includes an information publishing device, so the information publishing device can manage the time for these lighting devices simultaneously. Therefore, even when deploying this lighting system across time zones or countries, time configuration issues such as time zone conversion and daylight saving time adjustment can be easily completed. Therefore, the lighting system is more convenient to use and more flexible in application.
[0020] (4) In an embodiment of the present invention, the processing module of the lighting device can receive a local time signal through the first radio frequency signal module, and determine whether the difference between the local time signal and the current time of the timing module is within the calibration delay window. When the difference between the local time signal and the current time of the timing module is within the calibration delay window, the processing module delays the calibration of the current time of the timing module according to the preset delay time. When the difference between the local time signal and the current time of the timing module is higher than the upper limit of the calibration delay window, the processing module calibrates the current time of the timing module. When the difference between the local time signal and the current time of the timing module is lower than the lower limit of the calibration delay window, the processing module does not calibrate the current time of the timing module. Through the above calibration delay window delay calibration mechanism, the lighting device does not need to perform time calibration frequently, further reducing the energy consumption of the lighting device.
[0021] (5) In an embodiment of the present invention, the processing module of the lighting device receives a lighting configuration signal through the first radio frequency signal module and controls its light-emitting module according to the lighting configuration signal. Therefore, the user can perform lighting configuration settings (such as group setting, brightness setting, color temperature setting, etc.) through the electronic device, and transmit the corresponding lighting configuration signal to all lighting devices through the information publishing device to achieve the desired lighting effect. Therefore, the use of the lighting system is more convenient and the application is more flexible. Brief Description of the Drawings

[0031] The following will refer to the relevant drawings to illustrate embodiments of an illumination device and an illumination system with a time calibration function according to the present invention. For the sake of clarity and convenience in the illustration of the drawings, the components in the drawings may be presented with exaggeration or reduction in size and proportion.

For ease of understanding, the same components in the following embodiments are labeled with the same symbols for illustration.
[0032] Please refer to Figure 1 , which is a block diagram of an illumination system with a time calibration function according to an embodiment of the present invention. As shown in the figure, the illumination system 1 includes a plurality of illumination devices 11 and an information publishing device 12. These illumination devices 11 can be evenly distributed in a default area (such as a building). The illumination system 1 may have only 1 illumination device 11, or have 2 or more illumination devices 11 (only 3 illumination devices are shown in the figure).
[0033] Of course, this embodiment is only used for illustration and not for limiting the scope of the present invention. Equivalent modifications or changes made according to the illumination system 1 with a time calibration function in this embodiment should still be included within the patent scope of the present invention.
[0034] Please refer to Figure 2 , which is a block diagram of an illumination device with a time calibration function according to an embodiment of the present invention. As shown in the figure, each illumination device 11 includes a processing module 111, a timing module 112, a first radio frequency signal module 113, a light emitting module 114, and a sensing module 115. The timing module 112, the first radio frequency signal module 113, the light emitting module 114, and the sensing module 115 are connected to the processing module 111.
[0035] In one embodiment, the processing module 111 can be a microcontroller (MCU), a central processing unit (CPU), an application specific integrated circuit chip (ASIC), a field programmable gate array (FPGA), or other similar components.
[0036] In one embodiment, the timing module 112 may be a real-time clock (RTC) chip or other components with timing functions.
[0037] In one embodiment, the first radio frequency signal module 113 may be a radio frequency signal antenna or other circuits with radio frequency signal transceiver functions.
[0038] In one embodiment, the lighting module 114 may be a light-emitting diode (LED), a light bulb, a fluorescent lamp or other similar components.
[0039] In one embodiment, the sensing module 115 may be a microwave sensor, an infrared sensor or other similar components.
[0040] Of course, this embodiment is only used for illustration and not for limiting the scope of the present invention. Equivalent modifications or changes made to the lighting system 1 with time calibration function according to this embodiment should still be included within the patent scope of the present invention.
[0041] Please refer to Figure 3 , which is a block diagram of the information publishing device of the lighting system with time calibration function according to an embodiment of the present invention. As shown in the figure, the information publishing device 12 includes a global satellite positioning module 122, a control module 121, a second radio frequency signal module 123 and a communication module 124.
[0042] In one embodiment, the control module 121 may be a microcontroller (MCU), a central processing unit (CPU), an application specific integrated circuit chip (ASIC), a field programmable gate array (FPGA) or other similar components.
[0043] In one embodiment, the global satellite positioning module 122 may be a GPS module or other existing satellite positioning modules.
[0044] In one embodiment, the second radio frequency signal module 123 may be a radio frequency signal antenna or other circuits with radio frequency signal transceiver functions.
[0045] In one embodiment, the communication module 124 may be a Bluetooth module, a WiFi module, a ZigBee module or other similar components.
[0046] As Figure 1 , Figure 2 and Figure 3 shown, the global satellite positioning module 122 of the information publishing device 12 receives the global satellite positioning signal Gs. The control module 121 of the information publishing device 12 generates a local time signal Ts according to the global satellite positioning signal Gs, and transmits the local time signal Ts to the first radio frequency signal module 113 of the lighting device 11 through the second radio frequency signal module 123.
[0047] The processing module 111 of the lighting device 11 receives the local time signal Ts through the first radio frequency signal module 113, and then calibrates the current time of the timing module 112 according to the local time signal Ts to update the current time of the timing module 112.
[0048] Through the above time synchronization mechanism, these lighting devices 11 can effectively perform time synchronization, so that the time settings of these lighting devices 11 can always be kept accurate. Therefore, these lighting devices 11 will not generate time errors after long-term operation, so as to meet the requirements of actual applications.
[0049] In addition, the information publishing device 12 can manage the time for these lighting devices 11 at the same time, so that these lighting devices 11 can effectively achieve time synchronization. In this way, the time settings of these lighting devices 11 can always be kept accurate. Therefore, the overall cost of the lighting system 1 can be greatly reduced to meet the requirements of different applications.
[0050] The control module 121 of the information publishing device 12 can receive the lighting configuration signal Ds through the communication module 124 of the information publishing device 12, and transmit the lighting configuration signal Ds to the first radio frequency signal module 113 of the lighting device 11. The processing module 111 of the lighting device 11 receives the lighting configuration signal Ds through the first radio frequency signal module 113 of the lighting device 11, and controls the light-emitting module 114 of the lighting device 11 according to the lighting configuration signal Ds.
[0051] Therefore, users can perform lighting configuration settings (such as group settings, brightness settings, color temperature settings, etc.) through an electronic device (such as a smart phone, tablet computer, notebook computer, etc.), and transmit the corresponding lighting configuration signal Ds to all lighting devices 11 through the information publishing device 12 through the communication module of the electronic device (such as a Bluetooth module) to achieve the desired lighting effect. Therefore, the lighting system 1 is more convenient to use and more flexible in application.
[0052] In addition, the communication module 124 of the information publishing device 12 can also be used to receive the local time signal Ts.
[0053] The sensing module 115 of the lighting device 11 can detect moving objects (such as people, vehicles, etc.) to generate a sensing signal. The processing module 111 of the lighting device 11 can then activate the light-emitting module 114 according to the sensing signal to achieve the automatic lighting function.
[0054] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made according to the lighting system 1 with a time calibration function in this embodiment should still be included within the patent scope of the present invention.
[0055] Please refer to Figure 4, which is a schematic diagram of the calibration delay window delay calibration mechanism of the lighting device with a time calibration function according to an embodiment of the present invention. As shown in the figure, the lighting device 11 also has a calibration delay window delay calibration mechanism. The processing module 111 of the lighting device 11 receives the local time signal Ts through the first radio frequency signal module 113 of the lighting device 11, and determines whether the difference between the local time signal Ts and the current time of the timing module 112 is within the calibration delay window TW.
[0056] If the processing module 111 of the lighting device 11 determines that the difference DV between the local time signal Ts and the current time of the timing module 112 is within the calibration delay window TW, the processing module 111 of the lighting device 11 delays the calibration of the current time of the timing module 112 according to the default delay time. That is to say, the processing module 111 of the lighting device 11 does not perform the calibration of the current time of the timing module 112 for the time being, but automatically performs the calibration of the current time of the timing module 112 after a preset delay time. The processing module 111 of the lighting device 11 will record the local time signal Ts and perform timing until the preset delay time has passed, and then automatically perform the calibration of the current time of the timing module 112 according to the preset delay time and the local time signal Ts.
[0057] If the processing module 111 of the lighting device 11 determines that the difference DV between the local time signal and the current time of the timing module 112 is higher than the upper limit UT of the calibration delay window TW, the processing module 111 of the lighting device 11 calibrates the current time of the timing module 112.
[0058] On the contrary, if the processing module 111 of the lighting device 11 determines that the difference DV between the local time signal Ts and the current time of the timing module 112 is lower than the lower limit LT of the calibration delay window TW, the processing module 111 of the lighting device 11 does not calibrate the current time of the timing module 112.
[0059] For example, the calibration delay window TW can be 3 - 8 seconds. Therefore, the upper limit UT of the calibration delay window TW is 8, and the lower limit LT of the calibration delay window TW is 3; the preset delay time can be 24 hours. If the difference DV is between 3 - 8 seconds, the processing module 111 of the lighting device 11 will record the local time signal Ts and start timing, and after 24 hours, calibrate the current time of the timing module 112 (update the current time of the timing module 112 by adding 24 hours to the time of the local time signal Ts). If the difference DV is 2 seconds (lower than the lower limit LT of the calibration delay window TW), the processing module 111 of the lighting device 11 will not calibrate the current time of the timing module 112. If the difference DV is 10 seconds (higher than the upper limit UT of the calibration delay window TW), the processing module 111 of the lighting device 11 will immediately calibrate the current time of the timing module 112. The calibration delay window TW, the upper limit UT of the calibration delay window TW, and the lower limit LT of the calibration delay window TW are only examples, and users can make appropriate adjustments according to actual sensitivity requirements. The present invention is not limited thereto.
[0060] Through the above calibration delay window delay calibration mechanism, the lighting device 11 does not need to perform time calibration frequently, further reducing the energy consumption of the lighting device 11.
[0061] Of course, this embodiment is only used for illustration and not for limiting the scope of the present invention. Equivalent modifications or changes made according to the calibration delay window delay calibration mechanism of this embodiment should still be included within the patent scope of the present invention.
[0062] Please refer to Figure 5 , which is a flowchart of the time calibration method of the lighting device according to an embodiment of the present invention. As shown in the figure, the method of this embodiment includes the following steps:
[0063] Step S51: Receive the local time signal.
[0064] Step S52: Determine whether the difference between the local time signal and the current time of the timing module is within the calibration delay window.
[0065] Step S53: If the difference between the local time signal and the current time of the timing module is within the calibration delay window, delay the calibration of the current time of the timing module according to the preset delay time.
[0066] Step S54: If the difference between the local time signal and the current time of the timing module is higher than the upper limit of the calibration delay window, calibrate the current time of the timing module.
[0067] Step S55: If the difference between the local time signal and the current time of the timing module is lower than the lower limit of the calibration delay window, do not calibrate the current time of the timing module.
[0068] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made according to the time calibration method of the lighting device in this embodiment should still be included within the scope of the patent of the present invention.
[0069] Although the steps of the methods described in the present invention are shown and described in a specific order, the operation order of each method can be changed, certain steps can be executed in the reverse order, or certain steps can also be executed simultaneously with other steps. In another embodiment, different steps can be implemented in an intermittent and / or alternating manner.
[0070] It is worth mentioning that existing lighting devices lack a time synchronization mechanism and require time calibration and other parameter configurations, which will significantly increase the overall cost of the lighting system. In addition, some existing lighting devices have a Real-Time Clock (RTC) chip, but these lighting devices still generate time errors after long-term operation. Moreover, when deploying these lighting devices across time zones or countries, time configuration issues such as time zone conversion and daylight saving time adjustment often cause serious problems. In contrast, according to an embodiment of the present invention, a lighting device includes a processing module, a timing module, and a first radio frequency signal module. The timing module is connected to the processing module. The first radio frequency signal module is connected to the processing module. The processing module receives a local time signal through the first radio frequency signal module, and then calibrates the current time of the timing module according to the local time signal to update the current time of the timing module. As can be seen from the above, the lighting device has a time synchronization mechanism, so it can effectively perform time synchronization, enabling the time setting of the lighting device to always remain accurate. Therefore, no time error will occur after the lighting device operates for a long time, enabling the lighting device to meet the requirements of practical applications.
[0071] Furthermore, according to an embodiment of the present invention, a lighting system not only includes a plurality of lighting devices, but also includes an information publishing device. Each lighting device is integrated with a radio frequency signal module. The information publishing device can manage the time for these lighting devices simultaneously, enabling these lighting devices to effectively achieve time synchronization. In this way, the time setting of these lighting devices can always remain accurate. Therefore, the overall cost of the lighting system can be significantly reduced to meet the requirements of different applications.
[0072] In addition, according to an embodiment of the present invention, the lighting system includes an information publishing device, so the information publishing device can manage the time for these lighting devices simultaneously. Therefore, even when deploying this lighting system across time zones or countries, time configuration issues such as time zone conversion and daylight saving time adjustment can be easily completed. Therefore, the lighting system is more convenient to use and more flexible in application.
[0073] In addition, according to an embodiment of the present invention, the processing module of the lighting device can receive the local time signal through the first radio frequency signal module, and determine whether the difference between the local time signal and the current time of the timing module is within the calibration delay window. When the difference between the local time signal and the current time of the timing module is within the calibration delay window, the processing module delays and calibrates the current time of the timing module according to the preset delay time. When the difference between the local time signal and the current time of the timing module is higher than the upper limit of the calibration delay window, the processing module calibrates the current time of the timing module. When the difference between the local time signal and the current time of the timing module is lower than the lower limit of the calibration delay window, the processing module does not calibrate the current time of the timing module. Through the above calibration delay window delay calibration mechanism, the lighting device does not need to perform time calibration frequently, further reducing the energy consumption of the lighting device.
[0074] Furthermore, according to an embodiment of the present invention, the processing module of the lighting device receives the lighting configuration signal through the first radio frequency signal module, and controls its light-emitting module according to the lighting configuration signal. Therefore, the user can perform lighting configuration settings (such as group settings, brightness settings, color temperature settings, etc.) through the electronic device, and transmit the corresponding lighting configuration signal to all lighting devices through the information publishing device to achieve the desired lighting effect. Therefore, the lighting system is more convenient to use and more flexible in application. As can be seen from the above, the lighting device and lighting system with time calibration function according to the embodiments of the present invention can indeed achieve excellent technical effects.
[0075] Please refer to Figure 6 , which is a block diagram of the information publishing device of the lighting system with time calibration function according to another embodiment of the present invention. As shown in the figure, the information publishing device 12 includes a global satellite positioning module 122, a control module 121, a second radio frequency signal module 123, and a communication module 124.
[0076] Different from the foregoing embodiment, in this embodiment, the information publishing device 12 further includes an auxiliary communication module 125. The communication protocol of the auxiliary communication module 125 is different from that of the communication module 124. In one embodiment, the auxiliary communication module 125 can be a CAT1 module, a WiFi module, a ZigBee module, or other similar components.
[0077] The control module 121 of the information publishing device 12 can receive the lighting configuration signal Ds through the auxiliary communication module 125 of the information publishing device 12, and transmit the lighting configuration signal Ds to the first radio frequency signal module 113 of the lighting device 11. The processing module 111 of the lighting device 11 receives the lighting configuration signal Ds through the first radio frequency signal module 113 of the lighting device 11, and controls the light-emitting module 114 of the lighting device 11 according to the lighting configuration signal Ds.
[0078] Therefore, users can configure lighting settings (such as group settings, brightness settings, color temperature settings, etc.) through an electronic device (such as a smartphone, tablet computer, laptop, etc.), and transmit the corresponding lighting configuration signal Ds to all lighting devices 11 through the communication module (such as a CAT1 module) of the electronic device via the information publishing device 12 to achieve the desired lighting effect.
[0079] In addition, the auxiliary communication module 125 of the information publishing device 12 can also be used to receive the local time signal Ts.
[0080] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made based on the information publishing device 12 of this embodiment should still be included within the patent scope of the present invention.
[0081] In summary, according to an embodiment of the present invention, a lighting device includes a processing module, a timing module, and a first radio frequency signal module. The timing module is connected to the processing module. The first radio frequency signal module is connected to the processing module. The processing module receives the local time signal through the first radio frequency signal module, and then calibrates the current time of the timing module according to the local time signal to update the current time of the timing module. As can be seen from the above, the lighting device has a time synchronization mechanism, so it can effectively perform time synchronization, enabling the time setting of the lighting device to always remain accurate. Therefore, no time error will occur even after the lighting device has been running for a long time, enabling the lighting device to meet the requirements of practical applications.
[0082] Furthermore, according to an embodiment of the present invention, a lighting system not only includes multiple lighting devices but also an information publishing device. Each lighting device integrates a radio frequency signal module. The information publishing device can manage the time for these lighting devices simultaneously, enabling these lighting devices to effectively achieve time synchronization. In this way, the time setting of these lighting devices can always remain accurate. Therefore, the overall cost of the lighting system can be significantly reduced to meet the requirements of different applications.
[0083] In addition, according to an embodiment of the present invention, since the lighting system includes an information publishing device, the information publishing device can manage the time for these lighting devices simultaneously. Therefore, even if this lighting system is deployed across time zones or countries, time configuration issues such as time zone conversion and daylight saving time adjustment can be easily completed. Therefore, the lighting system is more convenient to use and more flexible in application.
[0084] In addition, according to an embodiment of the present invention, the processing module of the lighting device can receive a local time signal through the first radio frequency signal module, and determine whether the difference between the local time signal and the current time of the timing module is within a calibration delay window. When the difference between the local time signal and the current time of the timing module is within the calibration delay window, the processing module delays and calibrates the current time of the timing module according to a preset delay time. When the difference between the local time signal and the current time of the timing module is higher than the upper limit of the calibration delay window, the processing module calibrates the current time of the timing module. When the difference between the local time signal and the current time of the timing module is lower than the lower limit of the calibration delay window, the processing module does not calibrate the current time of the timing module. Through the above calibration delay window delay calibration mechanism, the lighting device does not need to perform time calibration frequently, further reducing the energy consumption of the lighting device.
[0085] Furthermore, according to an embodiment of the present invention, the processing module of the lighting device receives a lighting configuration signal through the first radio frequency signal module and controls its lighting module according to the lighting configuration signal. Therefore, the user can perform lighting configuration settings (such as group settings, brightness settings, color temperature settings, etc.) through an electronic device, and transmit the corresponding lighting configuration signal to all lighting devices through an information publishing device to achieve the desired lighting effect. Therefore, the use of the lighting system is more convenient and the application is more flexible.
[0086] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described in this article, or equivalent structural or equivalent process transformations made using the content of the specification and drawings of the present invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the protection scope of the present invention patent.
