Abstract
The invention discloses a keyboard illuminating apparatus and relates to the technical field of illumination. The keyboard illuminating apparatus comprises a desktop computer keyboard, wherein the keyboard comprises keys and a panel around the keys, a plurality of metal bonding pads are bonded on the inner side of the panel at intervals, surface mounted device light emitting diodes are arranged on the bonding pads and are electrically connected with a master control module inside the keyboard, and the master control module is electrically connected with a photosensitive sensor. Compared with the prior art, the keyboard illuminating apparatus can sense the light intensity of the environment where the keyboard is located to automatically provide illumination.
Description
Technical field
The present invention relates to lighting technical field, the device of especially a kind of keyboard illumination for desktop computer.
Background technology
The keyboard of desktop computer generally comprise the panel around button and button, during use desktop computer, overwhelming majority computer user custom look at the tag operation on keyboard, and the display screen of a lot of desktop computer from keyboard in different table surface layer, once dimmed being just difficult to of ambient accurately searches out required operated key, indoor light must be must opened and keyboard could be conveniently used, and open indoor light and sometimes can affect other people, if being not turned on indoor light, the light bowed by screen is faint is then needed earnestly to search required operated key, now particularly inconvenient.
Summary of the invention
The technical problem to be solved is to provide a kind of keyboard illuminating apparatus, and it can solve the problem that computer-keyboard is inconvenient to operate when the light is dusky in the external world.
In order to solve the problems referred to above, the technical solution adopted in the present invention is: this keyboard illuminating apparatus, keyboard including desktop computer, described keyboard includes the panel around button and described button, clear width at described panel is pasted with several metal pads, being provided with patch light-emitting diode on described pad by electrically connecting with the main control module being located at described keyboard, described main control module electrically connects with light sensor.
In technique scheme, technical scheme is it may also is that the volume of described patch light-emitting diode is less than the space between the inner side of described panel and described keyboard more specifically.
Further: it is MCS-51 single-chip microcomputer that described main control module includes model.
Further: described light sensor includes comparator and the photoconductive resistance that model is LM393.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, by using the light intensity of light sensor sensing local environment, dying down setting value once light, main control module then drives patch light-emitting diode to light, and illuminates the keyboard of desktop computer, and computer user uses.
2, patch light-emitting diode is adopted to paste installation on the panel of keyboard, first patch light-emitting diode is welded on pad, again pad is pasted on the panel of keyboard, when needs are changed or keep in repair, directly take off the patch light-emitting diode and pad that are broken, change again, be easier and facilitate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the enlarged drawing of A.
Fig. 3 is the circuit block diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
nullSuch as Fig. 1、The embodiment of keyboard illuminating apparatus shown in Fig. 2 and Fig. 3，Keyboard 1 including desktop computer，This keyboard 1 includes the panel 3 around button 2 and this button 2，The through hole of wire traverse it is provided with mean in the bottom of this panel 3，Clear width at this panel 3 is pasted with some metal pads，Every pair of pad is provided with patch light-emitting diode 4，This patch light-emitting diode 4 is by electrically connecting with the main control module 6 being located within keyboard 2，This main control module 6 electrically connects with power supply 7 and light sensor 5，The volume of the button 2 adjacent with panel 3 is suitably reduced when not affecting normal use，The volume-diminished 5% of button adjacent with panel 3 in the present embodiment，The volume of patch light-emitting diode 4 is less than the space between inner side and the keyboard 2 of panel 3，It is MCS-51 single-chip microcomputer that main control module 6 includes model，Light sensor 5 includes comparator and the photoconductive resistance that model is LM393.
During work, after main control module 6 initializes, when light sensor 5 senses the intensity of light more than setting value, output high level is to main control module 6, and the patch light-emitting diode 4 that main control module 6 controls does not work；When light sensor 5 senses the intensity of light less than setting value, output low level is to main control module 6, and the patch light-emitting diode 4 that main control module 6 controls lights.Light intensity difference according to local environment decides whether to start light emitting diode 4.
