Description

Technical Field

[0001] This disclosure relates to the field of lighting control technology, specifically to a lighting control device and a lighting fixture. Background Technology

[0002] Currently, many luminaires incorporate rhythmic lighting to enhance user experience and functionality. This function allows luminaires to adjust color temperature and / or brightness based on real-time data, simulating natural light to support healthy circadian rhythms and improve quality of life. However, this relies on the luminaire acquiring real-time data, meaning it must be connected to the internet or continuously powered to obtain this information. This design doesn't align with the common practice of luminaires being powered off during normal use, nor does it consider how rhythmic lighting would function without an internet connection.

[0003] Therefore, how to obtain real-time information for lighting fixtures in the event of power outages or network disconnections has become an urgent problem to be solved. Utility Model Content

[0010] Optionally, the battery is a button cell battery, or the battery is a rechargeable battery.

Attached Figure Description

[0021] Figure 1 This is a schematic diagram of the structure of a lighting control device provided in an embodiment of the present disclosure;

[0022] Figure 2 This is a schematic diagram of the structure of a lamp provided in an embodiment of the present disclosure. Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0025] Figure 1 This disclosure provides a schematic diagram of the structure of a lighting control device according to an embodiment. (See diagram below.) Figure 1 As shown, the lighting control device includes:

[0026] Real-time clock circuit 1 and battery 2 are connected to real-time clock circuit 1. Battery 2 is used to supply power to real-time clock circuit 1 when the lighting control device is not connected to the power supply. Real-time clock circuit 1 is used to provide real-time time.

[0027] Controller 3 is connected to real-time clock circuit 1. Controller 3 is used to provide control signals based on the real-time time and rhythm curve provided by real-time clock circuit 1. The control signals are used to adjust the light emission parameters of the light-emitting elements in the lamp.

[0028] Specifically, the specific circuit structure of the real-time clock circuit 1 can be set by those skilled in the art according to the actual situation, and is not limited here. For example, the real-time clock circuit 1 is a real-time clock chip, but it is not limited to this.

[0029] Specifically, emission parameters may include color temperature and / or brightness, but are not limited to these.

[0030] Specifically, the controller 3 can communicate with the real-time clock circuit 1 to read the real-time time, and then query the light emission parameters corresponding to the real-time time provided by the real-time clock circuit 1 from the rhythm curve, and then generate a control signal based on the light emission parameters. For example, the controller 3 can read the real-time time of the real-time clock circuit 1; if the reading times out, it obtains the light emission parameters before the last time the light was turned off, and then generates a control signal based on the light emission parameters; if the reading does not time out, it queries the light emission parameters corresponding to the read real-time time from the rhythm curve, and then generates a control signal based on the light emission parameters. However, it is not limited to this.

[0031] Specifically, the real-time clock circuit has two power supply methods: when the power supply is on, the power supply provides power to the real-time clock circuit; when the power supply is off, the battery provides power to the real-time clock circuit.

[0032] Understandably, by using a built-in real-time clock circuit 1 and powering it with a battery 2, the time loss caused by the user turning off the light fixture can be avoided, which would result in no accurate time reference when the light is powered on again.

[0033] In this embodiment of the disclosure, since a real-time clock circuit 1 is built into the lamp and a corresponding battery 2 is configured to power the real-time clock circuit 1, the lamp can obtain the time even when the network is disconnected or the power is cut off.

[0034] Optionally, see [link to relevant documentation] Figure 1 The lighting control device further includes: a first power supply 4 and a second power supply 5. The first power supply 4 is connected to the second power supply 5. The first power supply 4 is used to convert the mains power (i.e., the user's power supply 220V AC power) into DC power and provide the DC power to the second power supply 5.

[0035] The second power supply 5 is connected to the real-time clock circuit 1 and the controller 3 respectively. The second power supply 5 is used to supply power to the real-time clock circuit 1 and the controller 3. When the second power supply 5 is not supplying power, the battery 2 supplies power to the real-time clock circuit 1.

[0036] Specifically, the specific circuit structure of the first power supply 4 can be configured by those skilled in the art according to actual conditions, and is not limited here. For example, the first power supply 4 includes an AC-DC power supply, wherein the AC-DC power supply includes rectification, filtering and voltage regulation circuits to ensure a stable output DC voltage, but is not limited thereto.

[0037] Specifically, the specific circuit structure of the second power supply 5 can be configured by those skilled in the art according to actual conditions, and is not limited here. For example, the second power supply 5 includes an auxiliary power supply, but is not limited thereto.

[0038] Specifically, after the user's 220V power supply is connected, the controller 3 is powered on and can immediately obtain the real-time time through the real-time clock circuit 1. Based on the real-time time and its own rhythm curve, the controller turns on the lamp with the corresponding light emission parameters. In this way, the lamp can display different light emission parameters depending on when it is turned on. For example, when the lamp is turned on late at night, the controller 3 will turn on in night light mode after detecting the time, providing a good user experience.

[0039] It is understood that in this embodiment, the real-time clock circuit 1 is powered by the second power supply 5 and the battery 2. When the second power supply 5 supplies power to the real-time clock circuit 1, the battery 2 does not need to supply power to the real-time clock circuit 1, thus saving the battery 2's energy. When the second power supply 5 does not supply power to the real-time clock circuit 1, the battery 2 can supply power to the real-time clock circuit 1, thus maintaining the normal operation of the real-time clock circuit 1 and ensuring the accuracy of the real-time time.

[0040] Alternatively, the battery may be a button cell or a rechargeable battery.

[0041] Specifically, the first power source 4 can be connected to the battery 2, and the first power source 4 is used to charge the battery 2 when it is not fully charged; and / or, the second power source 5 can be connected to the battery 2, and the second power source 5 is used to charge the battery 2 when it is not fully charged.

[0042] Specifically, the first power supply 4 and / or the second power supply 5 may include a battery management circuit. When the battery management circuit detects that the battery 2 is not fully charged, it can charge the battery 2 so that the battery 2 has enough power to maintain the operation of the real-time clock circuit 1 in the event of a power outage.

[0043] Optionally, see [link to relevant documentation] Figure 1 The lighting control device further includes a drive circuit 6, which is connected to a first power supply 4 and a controller 3. The first power supply 4 is used to supply power to the drive circuit 6, and the drive circuit 6 is used to drive the light-emitting element in the lighting fixture according to the control signal to adjust the light-emitting parameters of the light-emitting element.

[0044] Specifically, the specific circuit structure of the driving circuit 6 can be set by those skilled in the art according to the actual situation, and is not limited here. For example, when the light-emitting element is an LED lamp, the driving circuit 6 is an LED driving circuit.

[0045] Optionally, see [link to relevant documentation] Figure 1 The lighting control device further includes: a wireless communication circuit 7, which is connected to the controller 3. The wireless communication circuit 7 is used to receive the real-time time sent by an external electronic device via wireless communication. The controller 3 is used to update the real-time time of the real-time clock circuit 1 according to the real-time time sent by the external electronic device.

[0046] Specifically, the specific circuit structure of the wireless communication circuit 7 can be configured by those skilled in the art according to actual conditions, and is not limited here. For example, the wireless communication circuit 7 includes a Bluetooth chip (which has advantages such as low power consumption and low cost), a Zigbee communication module and / or a 433MHz communication module, etc., but is not limited to these.

[0047] Specifically, external electronic devices can be mobile phones, computers, tablets, remote controls, and other electronic devices that can obtain accurate real-time time.

[0048] Specifically, controller 3 can rewrite the time of real-time clock circuit 1 and read its stored real-time time. After obtaining the real-time time of the external electronic device, controller 3 can calculate the difference between the real-time time of real-time clock circuit 1 and the real-time time of the external electronic device. If the absolute value of the difference is greater than a preset threshold, the real-time time of real-time clock circuit 1 is rewritten to the real-time time of the external electronic device; otherwise, no action is performed.

[0049] It should be noted that the controller 3 and the wireless communication circuit 7 can be independent of each other, or the wireless communication circuit 7 can be integrated into the controller 3. This disclosure does not limit this.

[0050] It is understandable that, through wireless communication, the lighting control device can obtain the real-time time provided by an external electronic device, and then calibrate the real-time time of the real-time clock circuit 1 to ensure time accuracy. It is also understandable that, by combining the real-time time provided by the real-time clock circuit 1 with the real-time time obtained through wireless communication, the lighting fixture only needs to calibrate the real-time time of the real-time clock circuit 1 at intervals; at other times, the real-time time of the real-time clock circuit 1 is sufficient and does not require a network connection.

[0051] Alternatively, the real-time transmitted by the external electronic device can be network real-time or GPS real-time. This provides a more accurate real-time for the lighting control device, thereby ensuring the accuracy of the real-time time of the real-time clock circuit 1.

[0052] Optionally, the lighting control device further includes: a wired communication circuit connected to the controller 3, the wired communication circuit being used to receive real-time data transmitted by an external electronic device via a wired connection, and the controller 3 being used to update the real-time data of the real-time clock circuit 1 according to the real-time data transmitted by the external electronic device.

[0053] Specifically, the specific circuit structure of the wired communication circuit can be configured by those skilled in the art according to the actual situation, and is not limited here. For example, the wired communication circuit includes a USB interface, but is not limited to this.

[0054] Understandably, through wired communication, the lighting control device can obtain the real-time time from external electronic devices, and then calibrate the real-time time of real-time clock circuit 1 to ensure time accuracy. It is also understandable that by combining the real-time time provided by real-time clock circuit 1 with the real-time time obtained through wired communication, the lighting fixture only needs to calibrate the real-time time of real-time clock circuit 1 at intervals; at other times, the real-time time of real-time clock circuit 1 is sufficient, without the need for network connectivity.

[0055] This disclosure also provides a lighting fixture, which includes a lighting control device and a light-emitting element provided in any embodiment of this disclosure, wherein the lighting control device is connected to the light-emitting element. For example, Figure 2 This is a structural schematic diagram of a lamp provided in an embodiment of this disclosure. Figure 2 As shown, the drive circuit 6 and the light-emitting element 8 in the lighting control device are connected.

[0056] Specifically, lighting fixtures include, but are not limited to, ceiling lights, wall lights, floor lamps and / or table lamps.

[0057] Optionally, the light-emitting element 8 may include an LED, but is not limited to this.

[0058] It should be noted that since the lamps provided in this embodiment include a lamp control device, the lamps provided in this embodiment have the same beneficial effects as the lamp control device, and will not be described in detail here.

[0059] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
