With the improvement of the social life level, the spirit life and pursuit of people are improved, and pianos serving as treble and bass are also becoming popular.

For piano learners, they cannot be played apart from the score, and also need to watch the score at any time during the playing process. In order to enable a piano learner to view a score more clearly, therefore, piano lamps have been developed. The piano lamp can provide special illumination for the piano player so as to provide better light quality, so that the piano player can watch music scores more clearly.

For children practicing pianos, their self-control ability is limited, and the training process of the children needs to be supervised, otherwise, the children often stop to do other things in the training process, so that the time for actually practicing pianos remains, and the intermittent training process has little effect on training improvement of the children. Parents, however, are busy and cannot oversee child exercises anywhere and anytime. Thus, parents are faced with the challenge of effectively supervising the practice of a child without delaying the work.

The monitoring is carried out by utilizing the monitoring video at home, the monitoring video can have a monitoring dead angle, and whether the child sits in front of the piano can only be determined through the monitoring video, but the child cannot be determined to be truly playing the piano during practice.

Embodiment one:

as shown in fig. 1 to 5, the lighting device capable of recording the playing time of the musical instrument comprises a lamp holder 10, a lamp cap 20, a timer (not shown) and a detecting device. Specifically, the lamp socket 10 is used to be placed on the panel of the piano, and the bottom of the lamp socket 10 may be further provided with an adsorption base pad 60, by which the lamp socket 10 may be further firmly fixed on the panel of the piano. The lamp cap 20 comprises a lamp shell 21 and a light-emitting component 22, wherein the lamp shell 21 is connected with the lamp holder 10, the light-emitting component 22 is arranged in the lamp shell 21, and the light-emitting component 22 mainly has the main function of emitting light for illumination and mainly performs auxiliary illumination on music scores. The time counting means is installed in the lamp socket 10, and the time counting means is specifically provided for recording the duration of the piano being played, and the duration of the piano being played refers to, in particular, the duration of the keys being played. The detection device comprises a detection end 51 and a control end 52, the control end 52 is arranged in the lamp holder 10, and the connection modes among the control end 52, the detection end 51 and the timing device are all communication connection, and can adopt wired electric signal connection communication or wireless electromagnetic wave communication mode. The detection terminal 51 is provided for detecting whether the piano is played, and the detection terminal 51 generates a detection signal based on the detection result and supplies the detection signal to the control terminal 52, and the control terminal 52 is provided for receiving the detection signal from the detection terminal 51. When the control end 52 receives the detection signal sent by the detection end 51 and used for detecting that the piano is played, the control end 52 controls the timing device to start and time; when the control terminal 52 receives the detection signal transmitted by the detection terminal 51 to detect that the piano is not played, the control terminal 52 controls the timing device to stop timing.

When a child exercises to play a piano, the lighting device capable of recording the playing time of the musical instrument is applied to perform auxiliary lighting and simultaneously record the played time of the piano. The lighting device capable of recording the playing time of the musical instrument is placed on the panel of the piano, and the lamp cap 20 is lighted in an auxiliary manner toward the musical score, thereby providing better light quality and enabling the child to view the musical score more clearly. Meanwhile, in the process of practicing the piano by the child, the detecting terminal 51 of the detecting device can detect whether the piano is played in real time, and then the control terminal 52 of the detecting device controls the timing device to count time when receiving the detecting signal transmitted by the detecting terminal 51 and detecting the piano being played, or the control terminal 52 of the detecting device controls the timing device to stop counting time when receiving the detecting signal transmitted by the detecting terminal 51 and detecting the piano not being played, so that the time of practicing the piano by the child is recorded. Parents can clearly grasp the actual situation of the child practice playing piano by looking at the recorded time of the practice playing piano after working. Therefore, by applying the lighting equipment capable of recording the playing time of the musical instrument, high-quality lighting light is provided for children, an effective supervision function of parents on the children to practice playing the piano is realized, and the work of the parents is not delayed.

As shown in fig. 2, the detection end 51 includes a radar/microwave sensor 511, and the radar/microwave sensor 511 is installed in the lamp housing 21 or the lamp socket 10, and the lighting device of the present utility model is preferably installed in the lamp housing 21. In general, a music score is placed in the middle of a piano when a player plays the piano, and thus, a lighting device is also placed in the middle of a piano panel accordingly. At this time, the radar/microwave sensor 511 is preferably located at the middle position of the lamp housing 21, so that it is possible to perform auxiliary illumination better, and also to ensure that the sensing area covers the whole piano key area better, thereby detecting whether the piano keys are played more accurately. The radar/microwave sensor 511 may generate intermediate frequency signals of corresponding characteristics by the doppler effect of the moving object. The intermediate frequency signal contains part of the motion characteristics of the moving object. The detection range of the radar/microwave sensor 511 is effectively covered on the piano key area, and the radar/microwave sensor 511 can be used to detect the Doppler effect and the characteristics thereof generated by hand movements, particularly the up-and-down movements of fingers during playing of the piano, so that the Doppler effect generated by other movements can be distinguished and finally whether the piano is played or not can be detected. Once the radar/microwave sensor 511 detects that the piano is played according to the finger movements, the radar/microwave sensor 511 generates a detection signal that the piano is played, and the radar/microwave sensor 511 transmits the signal to the control terminal 52, so that the control terminal 52 controls the timing device to start timing. When the radar/microwave sensor 511 detects that the piano is not played by the same detection method, the radar/microwave sensor 511 generates a detection signal of the piano not played and transmits the detection signal not played to the control end 52, and the control end 52 controls the timing device to stop timing.

In the first embodiment of the present utility model, the lighting apparatus capable of recording the playing time of the musical instrument further includes a display device (not shown). The display device can be a part of the lighting equipment capable of recording the playing duration of the musical instrument, and can also be a separate module (such as a tablet computer, a mobile phone and other mobile communication devices), and the display device is used for displaying the time interval and the total duration of the piano played recorded by the timing device. Specifically, the lighting device capable of recording the playing duration of the musical instrument further includes a communication module 71, the communication module 71 is disposed in the lamp socket 10, and the display device is in communication connection with the communication module 71, so as to transmit data (in the prior art, the communication module 71 is an electronic product with very wide application and very mature technology, no design and manufacture are required, and only corresponding purchase is required in the electronic market, so that the structural composition, circuit design and other design contents related to the communication module 71 are not repeated here. When the display device is part of a lighting apparatus that can record the duration of the performance of the instrument, it may be provided on the housing of the lamp socket 10 as an intuitive display for displaying the time data. When the display device is a display of the mobile communication device, the timer device transmits the recorded time data to the mobile communication device through the communication module 71 and displays the time data.

The first damping member 34, the second damping member 35 and the torsion spring 32 cooperate to provide a damping force for the relative rotation of the lamp arm 30 and the lamp socket 10, so that the rotation process is smoother and more stable. Finally, the above parts are limited to the threaded male shaft 31 by a nut 36. The lamp arm 30 is provided in a hollow structure as a wiring space for electrical connection between the lamp socket 10 and the cap 20.

The connecting bracket 111 is further connected with the top end cover 13, the top end cover 13 is also in a shape of a truncated cone, and is matched with the top end of the main support frame 11 in size, and is used for covering and fixing the connecting bracket 111, and is optionally connected with the connecting bracket 111 through screws. The supporting main frame 11 is also provided with a groove for installing the control end 52 and the communication module 71, and the groove is connected with a hole in the center of the top of the supporting main frame 11, so that the control end 52 and the communication module 71 can be conveniently installed to perform wiring with other electric elements. The side of the supporting main frame 11 facing away from the groove is also provided with a line channel with a certain size for installing the cable 72, and the line channel is also connected with the central hole at the top of the supporting main frame 11 so that the cable 72 can be routed.

The bottom end cover 12 is equipped with the absorption base pad 60 towards the one side of piano still, and bottom end cover 12 and absorption base pad 60 can pass through glue adhesion.

As shown in fig. 3 and 4, the lamp base 20 includes a lamp housing 21, an upper housing 211, a lower housing 212, a light emitting assembly 22 and a diffusion plate 23. The lamp housing 21 is divided into an upper housing 211 and a lower housing 212, which are correspondingly arranged and connected by a clamping groove for wrapping the light-emitting component 22. The diffusion plate 23 is installed in the lower case 212 and disposed corresponding to the light emitting assembly 22, and a necessary light distribution is provided by a specific optical design of the diffusion plate 23.

Embodiment two:

the second embodiment is different from the first embodiment in the following points.

As shown in fig. 6, the detecting end 51 includes a photographing module 512, and the photographing module 512 may be mounted in the lamp housing 21 or the lamp base 10 (in this case, the photographing module 512 is a part mounted in the lighting device, and is preferably placed at a position capable of directly facing the lamp base 20 for photographing in the key area), and in addition, the photographing module 512 may be mounted on the lamp arm 30 in addition to being mounted in the lamp housing 21 or the lamp base 10; alternatively, it may be specifically configured to be placed outside the illumination apparatus and toward the key area (in this case, the photographing module 512 is a separate accessory with respect to the illumination apparatus and is communicatively connected through the communication module 71). When the photographing module 512 is disposed to be placed outside the lamp socket 10 and the lamp housing 21, the photographing module 512 may be selectively placed anywhere, for example, at a position on a wall or other desk where a key area can be photographed, etc. The photographing module 512 may preferentially extract contour features of hands appearing in the key area and finger features acquired based on the contour features through image processing, and further recognize a relative position change of the fingers and the keys, that is, a left-right offset amount of the fingers with respect to the keys and an up-down offset amount of the fingers and the keys, using an image processing technique, thereby detecting whether the keys of the piano are played. When the shooting module 512 detects that the finger starts to generate a relative position change with the key, the detection signal is transmitted to the control end 52, so as to control the timing device to start timing. When the photographing module 512 detects that the finger on the piano key is stopped from changing relative position to the key or completely leaving the key, it transmits the detection signal to the control terminal 52, and then controls the timer to stop timing.

In another implementation of the second embodiment, the shooting module 512 may be replaced with a microphone, the microphone may detect the sound of the piano, and similarly, the microphone may be installed in the lamp housing 21 or the lamp socket 10, and in this case, the microphone is a part of the lighting device, and in addition, the microphone may be installed in the lamp housing 21 or the lamp socket 10, and also may be installed on the lamp arm 30. Alternatively, the microphone may be specifically configured to be placed outside the lighting device (where the microphone is a separate accessory to the lighting device and is communicatively coupled via the communication module 71), where the microphone may be selectively placed anywhere, for example, on a panel of a piano, or under a piano, etc. The microphone can acquire various sound signals appearing around the piano in real time and acquire vibration-related characteristics of various sound sources by adopting time-frequency processing. When a child starts playing a piano, the piano sounds are captured by the microphone, and the main frequency characteristics in the sound are further extracted by using time-frequency processing. Since the vibration frequencies of sounds generated by the piano keys striking different strings are fixed and known, extracting and detecting the presence or absence of the characteristic of the vibration frequency of the corresponding piano string in the sound signal can effectively detect whether the piano is being played. When the microphone detects the sound of the piano being played, the detection signal is transmitted to the control terminal 52, which in turn controls the timing means to start timing. When the microphone detects that the piano sound is stopped, the detection signal is transmitted to the control terminal 52, and the timer is controlled to stop timing.

The second embodiment is similar to the first embodiment except for the above differences, and the details of the other structures are the same, which will not be described here again.

Embodiment III:

embodiment three is different from embodiment one in the following points.

As shown in fig. 7, the detection end 51 includes an accelerometer 513, and the accelerometer 513 may be mounted in the lamp housing 21 or the lamp base 10 (in this case, the accelerometer 513 is a part of the lighting device), and the accelerometer 513 may be mounted on the lamp arm 30 in addition to being mounted in the lamp housing 21 or the lamp base 10. Alternatively, the accelerometer 513 may be specifically configured to be placed outside the lighting device (in which case the accelerometer 513 is a separate accessory to the lighting device and communicatively coupled via the communication module 71). Preferably in the lamp holder 10 of the piano lamp, or in a place where piano vibration is likely to occur, such as a piano face or piano sound cavity, etc. The accelerometer 513 can acquire in real time acceleration changes at least 3 spatial orientation coordinates, which can be consistent with the vibration of the cavity of the piano during the piano playing. When the child starts playing the piano, the piano sounds and then causes the piano to vibrate, and the accelerometer 513 detects whether the piano is played by detecting acceleration changes generated by the piano vibrations. When the accelerometer 513 detects the vibration of the piano (i.e., the piano is played), the detection signal is transmitted to the control terminal 52, and the timer is controlled to start timing. When the accelerometer 513 detects that the piano stops vibrating (i.e., the child stops playing the piano), a detection signal is transmitted to the control terminal 52, and the timer is controlled to stop timing.

In comparison with the first embodiment, the third embodiment has the same structure except for the above differences, and will not be described herein.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
