Description

Illuminated keyboard

Technical field

The utility model is relevant for a kind of illuminated keyboard, refers to that especially a kind of position of pasting in light shield layer and reflector of avoiding comes unglued, and avoids light to be overflowed by the LGP side, can improve the illuminated keyboard of light utilization efficiency.

Background technology

Along with the progress of science and technology, illuminated keyboard will develop into the main flow of keyboard gradually, and illuminated keyboard can use in the more not abundant occasion of light.Particularly dispose the laptop of illuminated keyboard, more can let the user all can use laptop easily in various occasions.In addition, illuminated keyboard also can cooperate button and different colors is arranged, and asks the demand of dazzling to meet user's innovation.

See also a kind of illuminated keyboard structure shown in Figure 1; This convention illuminated keyboard 10 comprises LGP 11, light source 12, keyboard body 13, light shield layer 14, first reflector plate 15 and second reflector plate 16, and LGP 11 has incidence surface 111, exiting surface 112, bottom surface 113 and side 114, and light source 12 is disposed at the incidence surface 111 of LGP 11; Keyboard body 13 is disposed at the exiting surface 112 of LGP 11; Light shield layer 14 is disposed between the exiting surface 112 and keyboard body 13 of LGP 11, and bottom surface 113, the second reflector plates 16 that first reflector plate 15 is disposed at LGP 11 are disposed at the side 114 of LGP 11; LGP 11 is arranged in first reflector plate 15 and second reflector plate, the 16 formed accommodation spaces; Its characteristics are, in the light reflected back LGP 11 that effectively light source 12 is produced by second reflector plate 16, can significantly promote the luminous efficiency and the overall brightness of illuminated keyboard; Keeping under the prerequisite of same brightness; Also can effectively reduce the intensity or the quantity of light source, use the target that reaches power saving and reduce cost, though the structure of this convention illuminated keyboard 10 can significantly be improved the disappearance of traditional illuminated keyboard energy loss and luminous intensity and bad; But; Because light shield layer 14 and second reflector plate, 16 separated attitudes, the light of LGP 11 still can be spilt by the slit 17 between the light shield layer 14 and second reflector plate 16, influences light utilization efficiency.
