Abstract

The utility model discloses a piano with a light-emitting diode (LED) lamp. The piano with the LED lamps comprises a piano. The LED lamp is arranged at the edge of a top cover of the piano and electrically connected with a control panel, and is a lamp strip consisting of a plurality of LED units. According to the piano with the LED lamp, the LED lamp is arranged on the piano, and can provide relatively more sufficient light for a performer in a performance in an environment in which light is insufficient without additional illumination equipment, so that the overall atmosphere of the outside is not influenced. The control panel can control the LED lamp to present a diversity of forms, so that the graphic sense and visual effect of appearance of the piano are improved. For shops and large exhibition halls for selling pianos, the piano with the LED lamp can rapidly catch eyes and attract the attention of consumers. The LED lamp for the piano has the characteristics of low cost, simple mounting method and less improvement on the structure of the piano, and is convenient to popularize.

Description

The piano of band LED lamp

Technical field

The utility model relates to a kind of piano, particularly a kind of piano with the LED lamp.

Background technology

Although piano always appears in public with its exclusive characteristic, in nearly 200 years history, the piano outward appearance does not but all have too many noticeable change always.Nowadays, piano spreads all over the world, and it again not only is a kind of simple playing an instrument, and more becomes many families parlor with beautiful in the show-and-tell activity, unique scenery.All with black, Bai Weizhu, color is more single in the appearance design of present most pianos; The minority piano is designed with beautiful outward appearance, but cost is higher, is not suitable for the general user.

Summary of the invention

The utility model technical matters to be solved provides a kind of piano with the LED lamp, can illumination be provided for the pianist, and beautifies the appearance of piano.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of piano with the LED lamp, comprise piano, and be provided with the LED lamp at the edge of piano top cover, described LED lamp is electrically connected with control panel.

Described LED lamp is the lamp band that a plurality of LED unit is formed.

Described piano key wood below also is provided with the LED lamp.

Described control panel is positioned at a side of key wood.

Also be provided with the acoustic pickup or the vibration transducer that are used to obtain sound on the described piano, acoustic pickup or vibration transducer are electrically connected with the input end of control circuit.

A kind of piano that the utility model provides with the LED lamp; Through the LED lamp is set, when in the insufficient environment of light, playing, also can comparatively sufficient illumination be provided for the player on piano; Do not need to be equipped with light fixture in addition, thereby do not influence extraneous whole atmosphere.Through the control panel that is provided with, can control the form of expression that the LED lamp presents rich and varied property, reach the design sense and the visual effect that strengthen the piano outward appearance.The acoustic pickup or the vibration transducer that are provided with can obtain the intensity of playing music or the speed of rhythm; Thereby convert digital signal to, by the brightness or the flicker of the control circuit control LED lamp that is connected with control panel, and the conversion of color; For example; In the melody of releiving, adopt the light of cool colour, and in comparatively fierce melody, adopt the light of warm colour, the selection of color also can be by manual control certainly.

For shops and the large-scale exhibition room that piano is sold, be equipped with the LED lamp piano also can attract eyeball rapidly, cause potential consumer's concern.The characteristics that the LED light fixture that uses in the utility model has that cost is low, installation method is simple, little to the piano structural modification are fit to the general user and use, and also are convenient to promote.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the front view of the utility model.

Fig. 2 is the side view of the utility model.

Fig. 3 is the synoptic diagram of control panel in the utility model.

Fig. 4 is the circuit block diagram in the utility model.

Embodiment

In Fig. 1, Fig. 2 and Fig. 4, a kind of piano with the LED lamp comprises piano, is provided with LED lamp 1 at the edge of piano top cover, and described LED lamp 1 is electrically connected with control panel 2.The LED lamp can comprise that to the doorstep the music stand part all illuminates with whole piano during work.

Described LED lamp 1 is the lamp band that a plurality of LED unit is formed.Each LED unit can be homochromy, also can the time colored.

Described piano key wood below also is provided with LED lamp 1.The LED lamp that key wood below is provided with mainly has been a decorative effect.

In Fig. 3, described control panel 2 is positioned at a side of key wood.Through being installed in the light-emitting mode of the control panel 2 adjusting LED lamps on the key side rail; Can realize continuing color of the same race or gradual change color; Under gradual change look state, can select color conversion speed: several working ways such as 10S, 30S, 1M, 2M for example according to different needs.The utility model is selected to be installed in controller panel on the key side rail to the little characteristics in piano space capable of using, external pad pasting, and the sense of touch smooth, simple to operation, good looking appearance is with the piano one integrated mass.The LED color lamp that uses on the utility model provides 12V direct supply by the 220V transformer, does not influence the piano playing performance, and can promote the aesthetic appearance of piano.

Also be provided with the acoustic pickup or the vibration transducer that are used to obtain sound on the described piano, acoustic pickup or vibration transducer are electrically connected with the input end of control circuit.Intensity of sound size or rhythm speed that acoustic pickup or vibration transducer acquisition are played are converted into digital signal, according to the brightness and the color of this Digital Signals LED lamp in control circuit.A reference value for example is set, and in this reference value, LED lamp color is constant; In order to avoid too frequent flicker effects illuminating effect, when the intensity of sound is higher than this reference value, then the LED lamp is according to the intensity flicker of sound; And after a period of time did not have voice signal, then the LED lamp slowly extinguished.

Again for example, do not set reference value, according to the brightness of rhythm of playing and loudness of a sound control LED lamp, a delay value is set still for the connection of LED lamp fully, such scheme is suitable for the music of lively rhythm.

Through acoustic pickup or the vibration transducer that is provided with, can make the utility model obtain better to play expressive force, particularly at the stage of low-light, effect is especially remarkable.

The concrete regulatory function of control panel is following:

1, ON/OFF LED color lamp is arbitrarily realized separately or single or a plurality of color lamps of ON/OFF in groups.

2, can pass through manual adjustments LED lamp, realize separately or single or a plurality of color lamps of ON/OFF in groups, and in switching process, realize gradual change, for example gradually dark or subtract bright.

3, the user can through selecting different color lamp flicker schemes, can show the progressive switching effect that gradually goes out of light single or in groups according to the hobby of oneself.

4, manually select the color of LED lamp according to the rhythm of music, for example in the melody of releiving, adopt the light of cool colour, and in comparatively fierce melody, adopt the light of warm colour.
