Description

Lighting control system

This model relates to a control system, especially to a lighting control system.

Dimmable lamps have gradually appeared in life widely, such as table lamps, indoor lamps, ambient lamps...etc. Such dimmable lamps are usually equipped with several light sources and dimming controllers. When in use, just turn on the light source and pass the dimming controller to adjust the light emitted by the lamp to mix the light into a desired state. This kind of dimmable lamp can be used at home, it can adjust the circadian rhythm through dimming so that the indoor lighting can conform to the laws of nature. For example, adjust the color temperature to bluish in the morning to suppress melatonin and boost the spirits of users in the lighting range; adjust the color temperature to yellow in the afternoon and evening to help melatonin production and help The user sleeps.

Generally speaking, a dimmable lamp is a complete device by combining a light source and a dimming controller. When such lamps are used as indoor lamps in a general home environment, they often need to be installed on the ceiling and other places that are difficult for users to reach, which makes it difficult for users to access and operate the dimming controller. Therefore, it is often necessary to separate the dimming controller from the lamp and install it separately to facilitate user operation. However, in a general home environment, it is difficult to form an independent wired connection between the dimming controller and the light source without moving the decoration, which is more inconvenient for installation. In addition, for ease of use, a dimmable lamp can usually be preset with a predetermined light corresponding to a specific time, for example, the light is automatically adjusted to a softer state at night. However, dimmable lamps cannot record the time when there is no power. Therefore, when the dimmable lamp is turned off for a period of time and then turned on again, the light emitted by it will often deviate from the preset value at the current time point.

Therefore, it is necessary to make further improvements in the prior art to improve the convenience of installation and enable the light source to be adjusted in real time to a preset state in line with the current time point.

In view of this, the main purpose of the present invention is to provide a lighting control system that is convenient to install and enables the light source to be adjusted to a preset state in accordance with the current time point in real time.

In order to achieve the above and other objectives, the present invention provides a lighting control system, which includes a lighting controller and a lighting group. The lighting controller includes a timer, a processing module, and a wireless transmission module. The timer is used to provide a time signal. The processing module is used for generating a control signal corresponding to the time signal according to a light control parameter combination and the time signal. The light control parameter combination includes a plurality of time parameters corresponding to different time signals, and a plurality of control parameters respectively corresponding to the time parameters. The wireless transmission module broadcasts the control signal continuously or at intervals. The lighting group can be dimmed according to the control signal and includes a communication module. The communication module can be paired with the wireless transmission module and can receive the control signal. Wherein, the lighting group can be selectively turned off, and when turned on again, the communication module is paired with the wireless transmission module of the lighting controller, and receives the control signal for dimming.

With the above design, the lighting controller establishes a connection with the lighting group through wireless communication, so it can be installed independently, which is more convenient to set up; in addition, because the lighting controller can continuously provide control signals corresponding to the next time point, when When the lighting group is turned on, it can be adjusted to the preset lighting state in line with the current time point, which is convenient to use.

Please refer to Figure 1. The light control system shown is one of the preferred embodiments of the new model. The light control system allows the user to automatically adjust the light to the preset value at the current time when the light is turned on. In this embodiment, the lighting control system includes a lighting group 10, a lighting controller 20, a computing device, and a virtual sharing platform 40.

The lighting assembly 10 can be dimmed according to a control signal, and includes at least one light emitting device 11 and a communication module 12. At least one of the light-emitting devices 11 is used to adjust the illuminance according to the control signal. The light emitting device 11 includes a light source (not shown), and the light source is selected from the group consisting of light emitting diodes, incandescent lamps, halogen lamps, fluorescent lamps, high pressure gas discharge lamps, and neon lamps, but is not limited thereto. The light emitted by the light source is not limited to visible light, and may also include invisible light such as ultraviolet light and infrared light. The aforementioned communication module 12 can receive the identification signal for pairing, or be found by other devices for pairing. The communication module 12 can receive control signals from the paired device. The communication module 12 can be selected from but not limited to a Zigbee module, a Bluetooth module, a UWB module, an infrared module, or an ANT+ module. In this embodiment, a Bluetooth module is used.

The lighting set 10 can be selectively turned off, and when it is turned on again, it receives identification signal pairing through the communication module 12 for pairing; or, when it is turned on again, the lighting set 10 can be found by other devices and then paired. After the pairing is completed, the lighting group 10 can receive the control signal from the paired device, and perform dimming according to the control signal.

In a possible implementation aspect, the lighting set 10 includes a light emitting device 11 and a communication module 12. Wherein, the light emitting device 11 includes a plurality of light sources capable of emitting light of different wavelengths. The aforementioned light-emitting device 11 may adopt several light sources arranged on the same base, such as embedding several light-emitting diodes on a substrate, or embedding halogen lamps and incandescent lamps on a substrate, or embedding on a substrate Set incandescent lamps and fluorescent lamps, but not limited to this. The light-emitting device 11 can be exemplified but not limited to a four-crystal LED lamp, a three-crystal LED lamp, a double crystal LED lamp, a D65 light source, and a D75 light source. The communication module 12 receives control signals to adjust the light emission of the lighting group 10.

In another possible implementation aspect, the lighting set 10 includes a communication module 12 and a plurality of light emitting devices 11. The light-emitting devices 11 respectively emit light having a predetermined color temperature value or a predetermined spectral value, and each of the light-emitting devices 11 can emit light of different illuminance. In this way, users or manufacturers can combine light-emitting devices 11 with different color temperatures or spectra to mix into mixed light of specific color temperatures or spectra. Therefore, the illuminance of the lighting group 10 can be changed by adjusting the illuminance of each light-emitting device 11. For example, when the light-emitting device 11 adopts LED bulbs, different currents can be given to make each LED bulb emit light of different illuminance. There is no certain way to modulate the power supply, and it can be done in a conventional way. For example, the Bluetooth chip in the Bluetooth module has the ability to process control signals and can give different light sources different operating currents according to the control signals. The light-emitting devices 11 may be that all light-emitting devices 11 perform dimming according to the same control signal; it may also be that some of the light-emitting devices 11 emit light according to the same control signal, and the other light-emitting devices 11 emit light according to different control signals. The aforementioned control method may be determined according to needs. In this embodiment, all the light emitting devices 11 are dimmed according to the same control signal.

The lighting controller 20 includes a timer 21, a memory 22, a processing module 23, and a wireless transmission module 24. The timer 21 is used to provide a time signal. The memory 22 is used to store data required in the calculation process, such as variables, data tables, etc., and the light control parameter combination is stored in the memory 22. The processing module 23 is used for generating a control signal corresponding to the time signal according to the combination of the light control parameters stored in the memory 22 and the aforementioned time signal. The wireless transmission module 24 continuously or at intervals broadcasts control signals and identification signals for the lighting group 10 to identify and pair with it; or, the wireless transmission module 24 continuously or at intervals searches for the surrounding lighting groups 10 for pairing. And pair with it, and then transmit the control signal after pairing. The wireless transmission module 24 is selected from a Zigbee module, a Bluetooth module, a UWB module, an infrared module, or an ANT+ module, but is not limited thereto. In this embodiment, a Bluetooth module is used.

The light control parameter combination includes a plurality of time parameters corresponding to different time signals, and a plurality of control parameters respectively corresponding to the time parameters. Wherein, each control parameter of the light control parameter combination includes at least one of an illuminance parameter, a color temperature parameter, and a spectral parameter. In this way, when the processing module 23 receives the time signal provided by the timer 21, it can find the time parameter corresponding to the time signal and the control parameter corresponding to the time parameter from the light control parameter combination. Because the generated control parameter is a preset value corresponding to the current time point, when it is transmitted to the lighting group 10, the lighting group 10 can be adjusted to the preset light-emitting state at the current time point.

Referring to FIG. 2, in one of the feasible implementation aspects, the light controller 20 further includes a sensor group 25. The sensor group 25 includes at least one sensor (not shown in the figure), and the number of the sensors depends on the demand and there is no certain limit. According to the designed control parameters, the sensor is selected from an illuminance meter, a color thermometer or a spectrometer. The sensor is used to sense the illuminance value, color temperature value or spectrum value emitted by the lighting group 10 in the lighting area, and return the sensed value to the processing module 23. In this way, the processing module 23 can determine whether there is a difference between the returned illuminance value, color temperature value or spectral value and the illuminance parameter, color temperature parameter or spectral parameter in the light control parameter combination, and if so, according to the difference value The control signal given to each light-emitting device 11 is adjusted until the difference value does not exist or is less than a predetermined value.

Referring to FIG. 3, in another feasible implementation aspect, the light controller 20 further includes a sensor group 25 and an auxiliary light source 26. The control and operation of the sensor group 25 are as described above. The auxiliary light source 26 can be dimmed according to the control signal. In this way, the processing module 23 can determine whether there is a difference between the returned illuminance value, color temperature value or spectral value and the illuminance parameter, color temperature parameter or spectral parameter in the light control parameter combination. If so, the auxiliary light source 26 is dimmed according to the difference value to compensate for the difference value until it does not exist or is less than a predetermined value. Because the light controller 20 includes the auxiliary light source 26, in addition to being used as the auxiliary lighting set 10, it can also be used as a night light. In this way, the user only needs to use the light controller 20 of this embodiment as a night light used in their daily life, which can be used to upgrade to the new type of light control system, without adding cost burden.

When in use, the light controller 20 can be directly installed on a socket in the room to operate continuously. In this way, the control signal and the identification signal can be broadcast continuously or at intervals, and the lighting group 10 can be paired with and transmit the control signal immediately when it is turned on. The control mode between the lighting controller 20 and the lighting group 10 is not fixed, but there are at least the following two modes, so that the lighting group 10 can be adjusted to the preset lighting state at the current time point immediately after being turned on:

The first control mode: the light controller 20 broadcasts and outputs the identification signal and the control signal simultaneously. When the lighting group 10 is turned on again, the communication module 12 in the lighting group 10 can receive the identification signal and pair with the light controller 20. After the pairing is successful, the lighting group 10 will adjust the light according to the control signal received at the moment. In this way, when the lighting group 10 is turned on, the identification signal can be received for pairing, and it can be adjusted to the preset lighting state at the current time point in real time.

The second control mode: the lighting controller 20 continuously searches for opportunities, and when the lighting group 10 is turned on, they can be paired with each other. After the pairing is completed, the lighting controller 20 then outputs a control signal to the lighting group 10, so that the lighting group 10 performs dimming according to the received control signal. In this way, the wireless transmission module 24 of the lighting controller 20 can periodically search for whether there is a lighting group 10 that can be paired with it, and immediately adjust the light according to the current control signal after the lighting group 10 is turned on.

The computing device 30 can allow the user to edit the light control parameter combination, and transmit the edited light control parameter combination to the light controller 20 through signal connection with the light controller 20. The computing device 30 can be, but is not limited to, a desktop computer, a notebook computer, a tablet computer, a smart phone, or a PDA that can output image signals to the screen and has computing capabilities. Among them, mobile computing devices 30 such as tablet computers, smart phones, and PDAs can allow users to carry them to different places of use for operation. The way of signal connection between the computing device 30 and the lighting controller 20 is not fixed. It can be connected through the built-in wireless communication interface of the computing device 30. The lighting controller 20 can also be equipped with a wireless communication interface 27 to pair and connect with the computing device. , The method is not fixed, it depends on the needs.

Taking Figure 4 as an example, in a possible implementation manner, in the editing interface provided by the computing device 30, the time parameter D1, the illuminance parameter D2, and the spectral parameter D3 are editable by the user, and the set parameters will affect the lighting How does the controller 20 give control signals to the light emitting device 11? Fig. 4 also shows an illuminance value versus time relationship diagram F. The relationship diagram F is based on the time parameter D1 and the illuminance parameter D2 edited by the user, and is graphically displayed after being calculated by the calculating device 3030. In this embodiment, the illuminance parameter D2 is represented by "slope", which is the amplitude of the illuminance change over time, but in other possible implementation manners, the set illuminance parameter can also be changed to a target value. In the use situation where the light control parameter combination includes color temperature parameters, the selected light emitting device 11 should be capable of emitting different color temperatures, for example, one of the light emitting device 11 that can emit a color temperature of 2700K and the other that can emit a color temperature of 6000K. In combination, according to the color temperature parameter set by the user, the light controller 20 adjusts the color temperature of the emitted light by adjusting the light-emitting ratio of the two light-emitting devices 11. In other possible embodiments, the computing device 30 allows the user to directly edit the illuminance value, color temperature value, or spectral value versus time relationship diagram, and the computing device 30 converts the illuminance parameter, color temperature parameter, spectral parameter, and time according to the foregoing relationship diagram. parameter. In addition, the values measured by the illuminance meter, color thermometer, spectrometer, thermometer, and hygrometer can also be transmitted to the computing device 30 and displayed, so as to provide the user as a reference for dimming.

Referring to Figs. 5 and 6, in the usage scenario of this embodiment, the light controller 20 is standing on the socket and constantly sends out identification signals or searches for opportunities, and the lighting group 10 can be turned off as needed. When the lighting group 10 is turned on, the communication module 12 therein will be paired with the light controller 20. After the lighting group 10 is paired with the lighting controller 20 and a connection is established, the lighting group 10 will receive the control signal sent by the lighting controller 20 and then perform dimming. Because the control signal is sent by the processing module 23 of the light controller 20 according to the current time, and because the light control parameter combination can be edited by the user through the computing device 30 according to their own needs, the lighting group 10 is adjusted After the light is irradiated, it can meet the user's preset lighting level at the current time point, and meet his own needs. In this embodiment, it is preset that only one light emitting device 11 is controlled by the light controller 20, however, it may also need to be adjusted.
