Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See a kind of desk lamp of the present invention shown in Fig. 1 and Fig. 4, comprising: base 1, lamp stand 2, support 3 and lamp body 4.Lamp stand is located on base, and lamp stand is connected with base by the first rotating shaft vertically arranged, and lamp stand can be rotated along own axes.In other embodiments, can also be connected by other active connections such as rotating disks, such structure change still falls within protection scope of the present invention.Prop up and be set up in lamp stand top, support is connected with lamp stand by horizontally disposed second rotating shaft, and support can be rotated in perpendicular around the second rotating shaft.The lampshade that lamp body comprises taper and the bulb be located in lampshade, lamp body is fixedly connected with support front end.
Desk lamp is also provided with first sensor 21, second sensor 31, first photoelectric sensor 5, second photoelectric sensor 9, indicator lamp 6 and control device 7.First sensor is located on described base, for measuring the angle that lamp stand rotates.Second sensor is located on lamp stand, for measuring the angle of described holder pivots.First photoelectric sensor is 5 in the present embodiment, is evenly distributed in described base edge place, for detecting the intensity of illumination of the light that lamp body sends.Support front end is located at by second photoelectric sensor, for detecting external light intensity.Preferably, lamp body position and lampshade angle be set to can by the first photoelectric sensor total energy receive lamp body the light that sends.
Indicator lamp is 9, is evenly distributed in described base edge place, and indicator lamp is used to indicate the illumination scope of operation center position that described lamp body sends.Preferably, described indicator lamp colour temperature is set to the colour temperature being different from described lamp body, makes indicating effect more obvious, can differentiate rapidly the light of indicator lamp, prevents the problem of searching under lamp body illumination less than pilot light photograph.
Control device is electrically connected with described first sensor, the second sensor, the first photoelectric sensor, the second photoelectric sensor, indicator lamp, lamp body respectively, in order to the data obtaining described first sensor, the second sensor, the first photoelectric sensor, the second photoelectric sensor detect, and in order to the intensity of illumination of the On/Off and indicator lamp that control described indicator lamp.Described control device is also in order to control the unlatching of described lamp body, cut out and intensity of illumination.Preferably, control device adopts regulating circuit to regulate the voltage on lamp body, indicator lamp, thus regulates the intensity of illumination of lamp body and indicator lamp.
As the further optimization to the present embodiment, described control device is also electrically connected with man-machine interaction unit 8, and described man-machine interaction unit is in order to the numerical value showing described first sensor, the second sensor detects.Described man-machine interaction unit also comprises guidance panel, and described guidance panel is in order to input the intensity of illumination of the required illumination scope of operation.Described guidance panel can be button group, also can be touch-screen.Preferably, described man-machine interaction unit can be integrated on base, also can be arranged to remote controller in addition, or is arranged to application program thus can carries out remote control by the mobile terminal such as mobile phone, panel computer.Man-machine interaction unit thus carry out the man-machine interaction behaviors such as input and output by the wireless-transmission networks such as wifi/3G/2G/4G/ bluetooth and control device.
In working order, when change appears in the lamp body position of desk lamp, the intensity of illumination in the former scope of operation correspondingly also changes, as shown in Figure 2.If the result calculated is greater than the first sensor detection angle X that rotates of lamp stand and X is sent to control device, Y is also sent to control device by the angle Y that the second sensor detection support rotates.Control device passes through the length data of X, Y and support and lamp stand, can calculate the illumination scope of operation center that lamp body irradiates.Again by data that the second photoelectric sensor and the first photoelectric sensor detect, control device calculates the intensity of illumination on illumination scope of operation center, if the result calculated is less than former intensity of illumination, then control device controls to increase the voltage on lamp body, thus the effect that the intensity of illumination of light in the scope of operation keeping lamp body to send is constant.
And when the lamp body position of desk lamp changes, control device sends instruction and starts to the indicator lamp of corresponding illumination scope of operation center.And control device can according to the distance of illumination scope of operation center position base, regulate the voltage on corresponding indicator lamp, thus regulate the intensity of illumination of indicator lamp, then indicator lamp can send the light of corresponding length according to optical attenuation, light end is positioned at the illumination scope of operation center that lamp body irradiates just, namely complete accurately point out lamp body the action of the illumination activity center position penetrated of issuing permit.
Especially, as shown in Figure 3, when lamp stand rotates, the light that lamp body sends shifts, forward on another first photoelectric sensor from first photoelectric sensor, during the light of rear one first photoelectric sensor after receiving transfer, namely control device is sent a signal to, intensity of illumination received is separately sent to control device by this 2 first photoelectric sensor, control device can calculate judges that the intensity of illumination of lamp body is with or without change, and in conjunction with the external light intensity signal that the second photoelectric sensor detects, instruction is sent for lamp body, increase or reduce the voltage on bulb, thus keep original intensity of illumination.
And, after control device receives this signal, the instruction of unlatching is sent to the indicator lamp of a photoelectric sensor after correspondence, and the indicator lamp of closing corresponding to last photoelectric sensor, thus complete the indicator lamp of answering by changing the intensity of illumination of indicator lamp and Switch Controller, namely complete accurately point out lamp body the action of the illumination activity center position penetrated of issuing permit.
Pass through such scheme, each flexible connection point of desk lamp is arranged sensor, in order to detect the data of desk lamp when changing its form, and data separate control device is calculated, find accurate illumination scope of operation central point, and by the data that the first photoelectric sensor and the second photoelectric sensor detect, the intensity of illumination in the illumination scope of operation of desk lamp is calculated, thus increasing/reduce the intensity of illumination of lamp body, on maintenance scope of operation central point, intensity of illumination is constant.
And, each flexible connection point of desk lamp being arranged sensor, in order to detect the data of desk lamp when changing its form, and data separate control device being calculated, utilize indicator lamp accurately to point out illumination scope of operation central point, person easy to use in time, accurately finds illumination scope of operation central point.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
