Description
Technical field
The utility model relates to moving communicating field, particularly control travelling carriage (Mobile Station, MS) equipment of light-emitting device.
Background technology
Along with development of wireless communication devices, MS more and more becomes the means of communication of doing without even for a moment in people's daily life, yet because the limitation of technology, MS power consumption problem also more and more causes people's attention, before the MS battery technology temporarily can't make a breakthrough, reduce MS power consumption practical way beyond doubt by every means.In current techniques, some light-sensitive device just can satisfy above-mentioned requirements of saving energy.Below just analyzed from the character of light-sensitive device and control MS light-emitting device prior art two aspects.
The electrical properties of some semi-conducting materials can change because being subjected to illumination, promptly has the photoelectric effect phenomenon.Utilize the photoelectric effect of these semi-conducting materials, people have produced light-sensitive devices such as photo resistance, photoelectric diode, phototriode.
In these light-sensitive devices, the resistance of photo resistance can change because of illumination, after photodiode, photosensitive triode are subjected to illumination, and the increase that fails to be convened for lack of a quorum of the reverse leakage of PN junction, these character of light-sensitive device can be used to Photoelectric Detection, optoelectronic switch etc.
The screen of modern MS nearly all is to adopt LCD (Liquid Crystal Display, " LCD ").LCD is to utilize a kind of passive-type display device of light reflection or light modulation, generally need be under the bright environment or be provided with under the condition such as backlight and work.Therefore, the LCD of MS need use backlight to provide backlight, the demonstration that makes the MS operator can see screen clearly in the environment a little less than light is dark.
In addition, can operate the MS keyboard easily in the dark weak environment of light in order to make the MS operator, design has keyboard light in the MS, and the light of keyboard light appears by the translucent keycap of the button of the keyboard of MS, can make the operator see button clearly.
In current techniques, light-emitting devices such as above-mentioned screen background lamp and keyboard light generally use Light-Emitting Diode (Light Emitting Diode, LED).As shown in Figure 1, the control of the unified controlled module of the light on and off of light-emitting device.In order to save the power consumption of MS battery, MS only just lights light-emitting device when the operator operates MS, when MS had any button to be triggered, control module was sent the control signal of lighting a lamp to driver module, driver module is exported bright lamp drive signal to light-emitting device, lights light-emitting device.
But, though the control mode of said method is simple, but owing to do not consider the intensity of illumination of surrounding environment, as long as just light a lamp but there is button to be triggered, so this scheme disadvantage is: MS can not come light-emitting device is controlled according to the environment around the operator, and then also light light-emitting device when not required in operator's surrounding environment, caused the waste of MS battery.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:
As shown in Figure 2, equipment for control travelling carriage light-emitting device of the present utility model, be used for the screen background lamp of travelling carriage and place the keyboard light of button to control, comprise control module, driver module, photoelectric detective circuit, the three connects successively, wherein driver module links to each other with light-emitting device, wherein, photoelectric detective circuit utilizes light-sensitive device (as photo resistance, photodiode, phototriode etc.) intensity of illumination of detection surrounding environment, and in view of the above to control module output Photoelectric Detection output signal, control module is used to accept the Photoelectric Detection output signal, and Photoelectric Detection output signal and predefined threshold value compared, and then judge to the bright/control signal of turning off the light of driver module output, driver module is accepted the bright/control signal of turning off the light and is exported the bright/drive signal of turning off the light to light-emitting device in view of the above, thereby lights/extinguish light-emitting device.
Control device in the utility model can also comprise a timer, it is set in advance a timing value, when not having trigger condition to be detected in the timing value of described timer setting, described control module is exported the control signal of turning off the light to described driver module.
More than for controlling the equipment of light-emitting device, the MS that has comprised described control appliance, in order to realize function by illumination control light-emitting device, just must introduce the illumination of surrounding environment on the bright device of MS inside, for this reason, need on the MS housing, increase a loophole, the choice of location of loophole ambient lighting around can shine the position, in concrete the application, the place of proper position close screen above the MS screen, and can not be chosen in the back side of MS, because the intensity of illumination around the MS can not be correctly reflected at the MS back side; Can not be chosen in the Lower Half in the front of MS, because this position that to be the operator hold, loophole might be covered by MS operator's hand.Another kind of optionally position is the earpiece holes of MS, can not need extra openings like this.
As seen, key of the present utility model is to increase the photoelectric detective circuit part in the MS internal circuit, detect the intensity of illumination of surrounding environment, in the industry cycle, photoelectric detective circuit has various ways, different circuit forms or different light-sensitive devices can be realized photoelectric detection function, the photoelectric detective circuit that the utility model provides as shown in Figure 3, that is:
Photoelectric detective circuit comprises: photodiode (D1), triode (Q1), resistance (R1), resistance (R2).
The negative pole of photodiode (D1) links to each other with power supply (VCC), the positive pole of photodiode (D1) links to each other with resistance (R2) end, the other end ground connection of resistance (R2), the base stage of triode (Q1) is connected between photodiode (D1) positive pole and the resistance (R2), its grounded emitter, its collector electrode links to each other with power supply VCC by resistance (R1), and triode (Q1) collector electrode output level V0 is the Photoelectric Detection output signal.
When illumination, the leakage current of D1 increases, and the pressure drop on the R2 increases, and makes the Q1 conducting, the V0 output low level.When not having illumination or illumination not enough, the pressure drop on the R2 reduces, and Q1 is ended, and V0 exports high level.That is: when the photoelectric detective circuit output signal is low level, surrounding environment illumination abundance is described, need not to light maybe needs to extinguish light-emitting device; When the photoelectric detective circuit output signal is high level, surrounding environment illumination deficiency is described, need light light-emitting device.
By above embodiment, can find, in the MS internal circuit, increase a photoelectric detective circuit, detect ambient lighting intensity, thereby judge whether to light light-emitting device according to ambient lighting intensity,, greatly reduce the consumption of MS electric energy by the utility model; And on the internal circuit of MS, only increase simple photoelectric detective circuit, little to the change of MS circuit, cost is low.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; any those skilled in the art of being familiar with should understand in the technical scope that the utility model discloses; can do various changes to it in form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
