Abstract
The utility model relates to a luminous keyboard, wherein a thin-film circuit board is arranged in the shell of the keyboard. The top of the thin-film circuit board is provided with a transparent shell top plate and transparent keys. An electro-luminescent sheet is arranged between the shell top plate and the thin-film circuit board. The electro-luminescent sheet is connected with a power supply. The shell is provided with a photosensitive sensor. The photosensitive sensor is in circuit connection with the electro-luminescent sheet. Due to the adoption of the luminous keyboard, not only the illumination effect for people is realized, but also the brightness of the light source is automatically adjusted according to the brightness of the ambient light. Therefore, the electricity is saved. The luminous keyboard is better in practical effect.
