LED lighting device consistent with the present disclosure;
Reference will now be made in detail to exemplary embodiments of the invention, which are illustrated in the accompanying drawings. Hereinafter, embodiments consistent with the disclosure will be described with reference to drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. It is apparent that the described embodiments are some but not all of the embodiments of the present invention. Based on the disclosed embodiment, persons of ordinary skill in the art may derive other embodiments consistent with the present disclosure, all of which are within the scope of the present invention.
As shown in
The lighting devices may include a main LED lighting device 1 and a secondary LED lighting device 2. The main LED lighting device 1 and the secondary LED lighting device 2 may have structures similar to certain common lighting devices on the market, providing a power drive module 10 and a light-emitting module 11 that connects to the power drive module 10. Further, the main LED lighting device 1 and the secondary LED lighting device 2 may both include a control unit 15 and a speaker unit (an electro-acoustic conversion unit) 12 for audio play. The difference between the main LED lighting device 1 and the secondary LED lighting device 2 is that the main LED lighting device 1 further includes a wireless radio frequency (RF) module 13 and a wireless audio module 14, while the secondary LED lighting device 2 may further include just a wireless audio module 14. The wireless audio module 14 of the main LED lighting device 1 and the wireless audio module 14 of the secondary LED lighting device 2 can communicate with each other.
In addition, to accommodate changes of the music being played, the main LED lighting device 1 and the secondary LED lighting device 2 may each provide a control unit 15. According to different music being played, the control unit 15 can generate and output different pulse-width modulation (PWM) or pulse-frequency modulation (PFM) light-adjusting signals to the power drive module 10, therefore changing lighting color and/or color temperature of the lighting devices according to the music.
The implementation of changing lighting color and/or color temperature of the lighting devices according to music may include two options. One option is to provide a preset configuration in the lighting devices, which controls lighting colors, and color temperatures corresponding to different music styles. When the smart terminal sends to-be-played audio signals to the lighting devices, according to different music styles being played, the control unit 15 in the lighting devices may generate and output different PWM or PFM light-adjusting signals to the power drive module 10, therefore automatically changing the lighting color and color temperature of the lighting devices. Another option is that when the smart terminal sends the to-be-played audio signals to the lighting devices, the control unit 15 may receive and buffer music data in real time, such as volume and frequency spectrum data. According to the received real-time music data, the control unit 15 may generate and output different PWM or PFM light-adjusting signals to the power drive module, therefore changing the lighting color and color temperature of the lighting devices in real time.
Further, to accommodate scenario changes of the music being played, the main LED lighting device 1 and the secondary LED lighting device 2 may each provide a control unit 15. According to different music pieces being played, the control unit 15 can generate and output different PWM or PFM light-adjusting signals to the power drive module, therefore changing lighting color and color temperature of the lighting devices according to the music.
The implementation of changing lighting color and color temperature of the lighting devices according to music may include two options. One option is to provide a preset configuration in the lighting devices which configures lighting colors and color temperatures corresponding to different music styles. When the smart terminal 4 sends the to-be-played audio signals to the lighting devices, according to different music styles being played, the control unit 15 in the lighting devices may generate and output different PWM or PFM light-adjusting signals to the power drive module 10, therefore automatically changing the lighting color and color temperature of the lighting devices. Another option is that when the smart terminal 4 sends the to-be-played audio signals to the lighting devices, the control unit 15 may receive and buffer music data in real time, such as volume and frequency spectrum data. According to the received real-time music data, the control unit 15 may generate and output different PWM or PFM light-adjusting signals to the power drive module, therefore changing the lighting color and color temperature of the lighting devices in real time.
In the present disclosure, a number of the secondary LED lighting devices 2 may be configured according to practical needs. For example, a plurality of lighting devices may form a wireless speaker system with 2.0-channel, 2.1-channel, 4.1-channel, 5.1-channel or 7.1-channel.
In certain embodiments, the main LED lighting device and the secondary LED lighting devices may combine with one or more existing Bluetooth or wireless speakers through the wireless module to form a speaker system with more channels. For example, in a home environment, there is already a 2.1-channel wireless speaker system including one subwoofer and two satellite speakers. The main LED lighting device may connect to the existing 2.1-channel wireless speaker and three secondary LED lighting devices. The three secondary LED lighting devices may locate at different corners of the room. The audio signals may be transmitted from the main LED lighting device to the subwoofer, the two satellite speakers and the three secondary LED lighting devices, therefore forming a 5.1-channel speaker system.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the claims.
Without limiting the scope of any claim and/or the specification, examples of industrial applicability and certain advantageous effects of the disclosed embodiments are listed for illustrative purposes. Various alternations, modifications, or equivalents to the technical solutions of the disclosed embodiments can be obvious to those skilled in the art and can be included in this disclosure.
In certain embodiments consistent with the present disclosure, a user may use the smart terminal to preset a lighting adjustment program for one type of music (e.g., Jazz). For example, the smart terminal may have a defined sequence of lighting changes correspond to a piece of Jazz music. The smart terminal may transmit data to the control units of the lighting devices. When the smart terminal plays Jazz, the lighting of the LED lighting devices may be adjusted according to the pre-defined sequence.
In certain embodiments consistent with the present disclosure, a user application may also set lighting adjustment programs for other applications, such as certain computer games. For example, the user may use a smart terminal to define a lighting sequence for computer game A. During an active session of the computer game A, the lighting of the LED lighting devices may be set at a certain color/brightness level (e.g., dimmed to a certain level). The smart terminal may transmit data to the control units of the lighting devices. When the user finishes one user session of game A, the lighting of the LED lighting devices may be adjusted to a different color/brightness level (e.g., flashing or bright light). Further, when an event in game A happens in a user session (e.g., the user won bonus points), the lighting may also be adjusted to a certain color/brightness level. When a user play computer game A on the smart terminal, for example, the LED lighting may dim, flash, etc. according to various game events. Computer game A is exemplary; the smart terminal may design lighting adjustment programs for other applications in a similar manner.
In certain embodiments consistent with the present disclosure, the LED lighting devices may also provide a feedback to the speakers integrated into the lighting devices. For example, a user may play a piece of music that dims the lighting of the LED lighting devices in one room. If a second user comes into the room and turns up the brightness level of one or more of the LED lighting devices using the dimmer, the LED lighting devices may send a feedback signal to the speaker to turn down the volume of the music while increasing the brightness level. The smart terminal may also display the feedback information (e.g., “lights turned on”) on the user interface while adjusting the sound levels.
In certain embodiments consistent with the present disclosure, the LED lighting devices may also include motion sensors or other sensors. The control units may further incorporate the detected positions of users in one room when adjusting lighting levels in the room. For example, when adjusting the lighting level according to a piece of music, the control units may set the lighting around a user to be more bright (or at a warmer color, etc.) in comparison to the lighting in the corners of the room without any detected user.
Comparing to the prior art, the disclosed wireless music-modulated lighting method and system can display music changes, automatically change lighting atmosphere according to the music style being played, and change lighting color and color temperature of the lighting devices, therefore providing more desirable user experience.
