[0002] With the increasing popularity of traditional and digital pianos, piano learning has become a major hobby, and the piano instruction market is maturing. To enhance the piano instruction experience, products are now available that feature indicator lights (to indicate key positions) mounted behind or below the keys. These illuminated keys on keyboard instruments use LEDs as their light source, which illuminate the entire transparent object evenly.

[0003] In the prior art, light is irradiated from the top of the keys and then refracted onto the keyboard, causing some attenuation of the light. This attenuation can be compensated by increasing the power of the light source and the wavelength of the light. Summary of the Invention

The attenuated light can be compensated by increasing the power of the light source and the wavelength of the light, and to propose an LED light source refraction type luminous keyboard.

[0013] Furthermore, the surface of the luminous key body is provided with corrosion lines, which can increase the surface strength of the key.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The brightness of the refractive luminous key in this solution remains relatively consistent when it is in motion and when it is stationary;

[0016] 2. This solution solves the existing problem of glare from direct light, too bright light at the front and dark light at the tail, and uneven brightness.
