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.
