Description
(1) technical field
The relevant a kind of notebook of the utility model with automatic photoinduction formula keyboard back light function, particularly relevant a kind of notebook with an optical sensing subassembly with detection light luminance and then activation backlight function.
(2) background technology
General notebook is identical with common personal computer, all need a finger-impu system cause user and knock keyboard so that data are imported computer-internal, under general situation, the user is when using a computer in the residing environment, also need the illumination of certain light luminance keyboard correctly could be knocked and unlikely makeing mistakes, if the user is lacking illumination, perhaps or even in the dark surrounds of dull thread illumination use a computer, be under the very weak situation of indoor power failure light for example, or in the operating environment of dark, then obvious meeting produces suitable not convenient to user's operation.It is that keyboard Designing is become to have backlight function that a kind of solution is arranged, and makes this key board unit can produce the irradiation of light, and allows the user be seen each button of this keyboard.
Seeing also Fig. 1, is for commonly using the synoptic diagram of the notebook that uses backlight function.As shown in Figure 1, have a display screen 10 and a key board unit 11 on one notebook 1, when the user feels insufficient light and will use backlight functions to keyboard 11 time, the user must knock and switched with the function key in the keyboard 13, that is be that mode with switching key activates backlight function, yet usually when needs use backlight function, be in the environment of insufficient light often, if also will be in insufficient light or dark these function keys 13 of middle searching, well imagine and to bring many inconvenience also to be difficult for finding correct button, even can push the wrong button and input erroneous data and cause misoperation.
(3) utility model content
Fundamental purpose of the present utility model provides a kind of can the detection outside ambient light brightness, and activates the notebook of the automatic backlight function in the keyboard when insufficient light.
The utility model provides a kind of notebook with automatic photoinduction formula keyboard back light function, and the notebook with automatic photoinduction formula keyboard back light function comprises: a main frame has a power supply; One screen; One keyboard is arranged on the main frame; One back light member is under setting and the keyboard, to illuminate described keyboard when described power supply is powered; One optical sensing subassembly is arranged on the notebook, and electrically connects with described back light member, will the testing result of light be sent to this notebook, whether activates backlight function to determine this key board unit.
Because design has an optical sensing subassembly (such as photistor or light emitting diode) in notebook, this optical sensing subassembly light to external world detects, and transmit signals to the inside of this notebook, whether activate backlight function with the key board unit in the decision notebook, usually in the dark space of an insufficient light or in special working environment, get final product the light luminance of automatic induced environment by the optical sensing subassembly that uses the notebook computer system power supply, when the context insufficient light, activate the backlight function in the keyboard, to allow the user be used the keyboard of sufficient light illumination, smoothly data are inputed in the computing machine.
For further specifying the purpose of this utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.
(4) description of drawings
Fig. 1 is the notebook synoptic diagram of commonly using.
Fig. 2 is the synoptic diagram of a preferred embodiment of the notebook with optical sensing subassembly of the present utility model.
Fig. 3 is the synoptic diagram of the optical sensing subassembly in the utility model preferred embodiment to light sensing.
Fig. 4 activates the synoptic diagram of a backlight function for key board unit in the utility model preferred embodiment.
(5) embodiment
The utility model discloses a kind of notebook with automatic photoinduction formula keyboard back light function, be one optical sensing subassembly to be arranged in the notebook design, this optical sensing subassembly can be sent to the detection signal to light this notebook, whether activate backlight function with the key board unit in the decision notebook, usually in the dark space of an insufficient light or in special working environment, light luminance by the automatic induced environment of optical sensing subassembly, when the context insufficient light, activate the backlight function in the keyboard automatically, and need not activate with manual mode, to allow the user be used to have the keyboard of sufficient light illumination, smoothly data being inputed in the computing machine, and avoid wrong situation to produce.
Seeing also Fig. 2, Fig. 3 and Fig. 4, is preferred embodiment of the present invention shown in the figure.As shown in Figure 2, this preferred embodiment of the present utility model is provided with an optical sensing subassembly, this optical sensing subassembly 22 is arranged on the same plane of the display screen 20 of a notebook 2, design is for making optical sensing subassembly 22 obtain that to arrive the brightness of irradiate light of this display screen 2 identical with light from environment in conplane purpose, make the detection induction of 22 pairs of light of this optical sensing subassembly approach human eye watching to screen 20 devices, and make optical sensing subassembly 22 when insufficient light, send a signal to these computing machine 2 inside, make relevant action again and activate a backlight function, after backlight function is activated, can make the user obtain sufficient light and use keyboard 21 to activate these keyboard 21 devices.
As shown in Figure 3, it be in this preferred embodiment of the utility model an optical sensing subassembly to the synoptic diagram of light sensing.When the utility model after computing machine 2 power supplys activate, optical sensing subassembly 22 environment is to external world detected, and can judge whether light sufficient, and can issue a signal transmitted to computing machine 2 inside to carry out follow-up action under the insufficient light situation.
See also Fig. 4, it is the synoptic diagram that key board unit activates a backlight function in the utility model preferred embodiment.When optical sensing subassembly 22 detects insufficient light, the signal that computing machine 2 is received insufficient light promptly activates the backlight function of key board unit 21, make the user when visual keyboard 21, can obtain the irradiate light of adequate brightness, to prevent wrong data input action, also make the user successfully to use a computer 2.
As described in above-mentioned preferred embodiment, wherein said optical sensing subassembly can be photistor, optically-coupled resistance or optical diode or can the light sensing to send the electronic package of signal.In addition, the electric power supply of this optical sensing subassembly is the system power supply from this notebook, that is is promptly to give activating this optical sensing subassembly and can carrying out the light measuring ability after this notebook start.
Announcement by above-mentioned preferred embodiment as can be known, design of the present utility model can make notebook still can use smoothly when insufficient light, except that the operation inconvenience that can avoid the user, also can overcome the disappearance of located by prior art, to promote the purpose that under particular surroundings, still can use smoothly of notebook.
