A kind of intelligent mobile phone illuminating lamp
Technical field
The utility model relates to a kind of mobile device, particularly a kind of mobile phone illuminating lamp.
Background technology
Along with developing rapidly of mobile phone, the user is also more and more higher for the requirement of mobile phone additional function, at present, mobile phone that can night illumination quite is subjected to user's favor, its general structure is that an illuminating lamp is installed in mobile phone the place ahead, after pressing lighting switch, this illuminating lamp can throw light on, and this is very practical when opening door lock night.
Yet present mobile phone lighting brightness is substantially invariable, and promptly under the normal situation of mobile phone electric power, brightness of illumination is nonadjustable, and like this, its illumination flexibility under various different lightness environment is just poor, and certainly, its temperament and interest is also not enough.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of intelligent mobile phone illuminating lamp, and this illuminating lamp can be regulated brightness automatically or artificially according to different outside photoenvironments, has fabulous illumination flexibility and temperament and interest.
The scheme that its technical problem that solves the utility model adopts is: this intelligent mobile phone illuminating lamp comprises lamp holder, lighting button, light sensor, Power Management Unit, described Power Management Unit is the Current Control chip, its input and battery of mobile phone, mobile phone CPU, described light sensor are electrically connected, and its output is electrically connected with described lamp holder behind described lighting button; This intelligent mobile phone illuminating lamp also comprises a supporting Control Software, is stored in the mobile phone storage equipment.
As preferably, described lamp holder is a LED lamp, its good energy saving property, brightness of illumination height.
As preferably, described lamp holder is in parallel with an electric capacity at least, exchanges clutter with filtering, makes lamp holder luminous more stable.
As preferably, described Power Management Unit comprises a pulse-width modulation circuit, and this pulse-width modulation circuit can be regulated the pulse period width of output current according to described mobile phone cpu instruction or described light sensor signal between 1%-100%.
As preferably, described Control Software starts when described lighting button is closed voluntarily, and changes running background over to, and closes voluntarily when described lighting button disconnects.
The beneficial effects of the utility model are: this intelligent mobile phone illuminating lamp in use, only need press lighting button, the Control Software of then throwing light on is moved automatically, under the situation of acquiescence, Power Management Unit is regulated output current voluntarily according to the ambient brightness signal of light sensor sensing, the brightness of illumination of control lamp holder conforms automatically; Under the situation that the user manually controls by Control Software, then mobile phone CPU is according to the output parameter of software, the output control signal is given Power Management Unit, thereby the brightness of illumination of control lamp holder, this illuminating lamp can be regulated brightness automatically or artificially according to different outside photoenvironments, has fabulous illumination flexibility and temperament and interest.
Description of drawings
Fig. 1 is the outside drawing of this intelligent mobile phone illuminating lamp.
Fig. 2 is the structured flowchart of this intelligent mobile phone illuminating lamp.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1, Fig. 2 are the displayings of an embodiment, this intelligent mobile phone illuminating lamp comprises lamp holder 2, lighting button 1, light sensor 3, Power Management Unit 6, described Power Management Unit 6 is the Current Control chip, its input and battery of mobile phone 4, mobile phone CPU5, described light sensor 3 are electrically connected, and its output is electrically connected with described lamp holder 2 behind described lighting button 1; In addition, this intelligent mobile phone illuminating lamp also comprises a supporting Control Software, is stored in the mobile phone storage equipment.
Above-mentioned intelligent mobile phone illuminating lamp, described lamp holder 2 is a LED lamp, its good energy saving property, the brightness of illumination height, it is installed in the depression of phone housing head.
Above-mentioned intelligent mobile phone illuminating lamp, described lamp holder 2 are in parallel with an electric capacity at least, exchange clutter with filtering, make lamp holder 2 luminous more stable.
Above-mentioned intelligent mobile phone illuminating lamp, described Power Management Unit 6 comprises a pulse-width modulation circuit, this pulse-width modulation circuit can be regulated (prior art) with the pulse period width of output current according to described mobile phone CPU5 instruction or described light sensor 3 signals between 1%-100%, as: when the pulse period of output current, width was 100%, be that output current is continuous interchange ripple, when the pulse period of output current, width was 50%, clipped the half period width in aforementioned continuous each cycle of interchange ripple, then exported half that electric energy has only continuous interchange ripple.
Above-mentioned intelligent mobile phone illuminating lamp, described Control Software starts when described lighting button 1 is closed voluntarily, and changes running background over to, and closes voluntarily when described lighting button 1 disconnects.
Above-mentioned intelligent mobile phone illuminating lamp in use, only need press lighting button 1, the Control Software of then throwing light on is moved automatically, under the situation of acquiescence, Power Management Unit 6 is regulated output current voluntarily according to the ambient brightness signal of light sensor 3 sensings, the brightness of illumination of control lamp holder 2 conforms automatically; Under the situation that the user manually controls by Control Software, then mobile phone CPU5 is according to the output parameter of software, the output control signal is given Power Management Unit 6, thereby the brightness of illumination of control lamp holder 2, this intelligent mobile phone illuminating lamp can be regulated brightness automatically or artificially according to different outside photoenvironments, has fabulous illumination flexibility and temperament and interest.
