Embodiment

Following foundation technological means of the present utility model lists and is suitable for execution mode of the present utility model, and cooperates graphic being described as follows:

As shown in Figure 1 and Figure 2, the utility model " desk lamp automatic light modulation device " is that an OPTICAL SENSORS 10, a central processing module 20, and one drive circuit 30 are set on desk lamp 100, wherein:

OPTICAL SENSORS 10 can be installed in the diverse location on the desk lamp 100, so that light intensity by the indoor diverse location of OPTICAL SENSORS 10 monitorings, and monitoring result is sent in the central processing module 20, the light strong and weak signals that these central processing module 20 meetings are transmitted according to OPTICAL SENSORS 10, the fluorescent tube 101 that control Driver Circuit 30 is ordered about on the desk lamp 100 carries out the action of light filling or dim light.

Referring to Fig. 2, its concrete function mode is, the 1st step, when aforementioned OPTICAL SENSORS 10 monitors the reverberation of the light of interior space environment or light sensitive surface or light intensity that computer screen sends, the signal of this light intensity is sent to central processing module 20 by OPTICAL SENSORS 10, the 2nd step, this central processing module 20 can judge that whether this monitored signal is greater than set point, if, then represent extraneous light too strong, then carried out for the 3rd step, central processing module 20 just control Driver Circuit 30 orders about fluorescent tube 101 and must carry out the action of dim light; If not; a little less than then representing extraneous light too; then carried out for the 4th step; central processing module 20 just control Driver Circuit 30 orders about fluorescent tube 101 and must carry out the action of light filling; make fluorescent tube 101 give out light and be all the impression that meets human visual; avoid the user that the tired situation of vision takes place, and reach the purpose of vision protection.

During enforcement, for making OPTICAL SENSORS 10 monitor the reflection ray of diverse location such as space environment or light sensitive surface reverberation or computer screen reverberation in the aforementioned compartment, can be with the different parts that the position is installed in desk lamp 100 that is provided with of OPTICAL SENSORS 10, as lampshade 102 tops of desk lamp 100, side, below etc.

For example, as shown in Figure 3, this OPTICAL SENSORS 10 is installed in lampshade 102 belows of desk lamp 100, then this OPTICAL SENSORS 10 can be monitored the reflection ray signal from sensitive surface, the power of this reflection ray is the relative position that depends on lampshade 102 and sensitive surface, this lampshade 102 is higher with the distance of sensitive surface, the light of assembling sensitive surface promptly can be not good, at this moment, central processing module 20 promptly can be according to OPTICAL SENSORS 10 monitored signal, the stronger light of fluorescent tube 101 outputs that orders about desk lamp 100 carries out light filling, otherwise, if lampshade 102 is lower with the distance of sensitive surface, the light of assembling sensitive surface promptly can be preferable, and central processing module 20 promptly can order about the more weak light of fluorescent tube 101 outputs and carry out dim light; In addition, the reverberation of sensitive surface is also relevant with the sensitive surface color, if sensitive surface is dark-coloured system, then can be subjected to luminous reflectanc relatively poor because of own, make collected light not good, therefore, the fluorescent tube 101 that central processing module 20 can order about desk lamp 100 can carry out light filling by the higher light of output, carries out dim light otherwise then export than decreased light.

Moreover; as shown in Figure 4; this OPTICAL SENSORS 10 also can be installed in lampshade 102 sides of desk lamp 100; to receive from the light of computer screen itself or from the light of other sides; when the user uses computer; OPTICAL SENSORS 10 on this desk lamp 100 promptly can receive the light that distributes from computer screen; and the light intensity that distributes according to computer screen; fluorescent tube 101 by central processing module 20 order desk lamps 100 reduces light output according to its light intensity; make and be projeced into the screen light attenuation; it is minimum to cause dazzle to be reduced to, and reaches the effect of vision protection.

Perhaps, as shown in Figure 5, this OPTICAL SENSORS 10 also can be installed in lampshade 102 tops of desk lamp 100, to receive from the existing light on the indoor ceiling or the light of other indoor environments, when on the ceiling other light sources being arranged, this central processing module 20 is promptly controlled the more weak light of fluorescent tube 101 outputs of desk lamp 100, avoid influencing user's operation, reducing the fatigue of eyes, and reduce the output of light because of fluorescent tube 101, make the energy can not cause repetition and waste, reduce electricity charge expenditure relatively; If when not having other light sources on the indoor ceiling, can control the fluorescent tube 101 outputting standard light of desk lamp 100, use for the people.

In addition, what deserves to be mentioned is that above-mentioned central processing module 20 does not limit the module aspect, can form by multiple mode during enforcement, wherein a kind of possible implementation is that central processing module 20 comprises a comparing unit 21 and a converter unit 22, and its workflow mode can be consulted Fig. 5, shown in Figure 6:

One OPTICAL SENSORS 10, a central processing module 20 are set on desk lamp 100, reach one drive circuit 30, this central processing module 20 comprises a comparing unit 21 and a converter unit 22, wherein:

Be arranged on the lampshade 102 to monitor light or the reverberation of light sensitive surface or the light intensity that computer screen sends of interior space environment by OPTICAL SENSORS 10, and the light intensity signal is sent to central processing module 20, by the light intensity signal of 21 receptions of the comparing unit in this central processing module 20 from OPTICAL SENSORS 10, and after this signal and set point made comparisons, comparative result is sent in the converter unit 22 again, this converter unit 22 can be exported the voltages of different sizes or electric current to drive circuit 30 according to comparative result, drive circuit 30 orders about the light of the fluorescent tube 101 generation varying strengths of desk lamp 100, to reach the purpose of automatic adjustment light.

Perhaps, central processing module 20 also can adopt another kind of feasible mode when implementing, and promptly central processing module 20 can use the microprocessor 23 of a multiple circuit of energy computing to replace, and its workflow mode can be consulted Fig. 5, shown in Figure 7:

One OPTICAL SENSORS 10, a central processing module 20 are set on lampshade 102, reach one drive circuit 30, this central processing module 20 is a microprocessor 23, wherein:

This OPTICAL SENSORS 10 is monitored the power of desk lamp 100 extraneous lights or reflection ray, and monitor signal is sent to central processing module 20; This central processing module 20 is that microprocessor 23 receives the signals from OPTICAL SENSORS 10, and with this signal and set point do one relatively after, export different big or small voltages or electric current to drive circuit 30 according to result relatively again; Drive circuit 30 receives voltage or the current signal that is transmitted from microprocessor 23, and according to voltage that is received or current signal size, the fluorescent tube 101 that orders about desk lamp 100 produces the light of varying strength, to reach the purpose of automatic adjustment light.
