The beneficial effects of the utility model are: the illuminating lamp in the clock and watch is connected with the sensitization control device, this device can be opened or the pass illuminating lamp automatically according to the strong and weak of light, not only make things convenient for see the time in evening, also desk lamp and even household have been played the cosmetic decoration effect, increased modern's delight of life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic appearance of the present utility model;
Fig. 2 is the switch connection diagram of embodiment;
Fig. 3 is an embodiment control circuit block diagram;
Fig. 4 is the embodiment electrical block diagram.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of desk lamp that has clock and watch sensitive illuminance device of the present utility model, comprise pedestal 1, column 2 and lampshade 3, main lamp body 4 is installed in the lampshade 3, pedestal 1 is provided with switch 5 and clock and watch 6, clock and watch 6 are provided with illuminating lamp 7, and this illuminating lamp 7 is connected with sensitization control device 8, and the photosensitive-member 9 of sensitization control device 8 is installed on pedestal 1, column 2 or the lampshade 3 that can respond near the light of clock and watch.
Wherein, as preferred implementation, the photosensitive-member 9 of described sensitization control device 8 is installed in the through hole 10 that pedestal 1 offered.
Wherein, described clock and watch 6 can be liquid crystal clock and watch or analog timepiece etc.
In addition, with reference to Fig. 3, Fig. 4, further, described illuminating lamp 7 is LED lamps, and described sensitization control device 8 includes bleeder circuit 81, rectification circuit 82, constant-current device 83, control circuit 84 and the photosensitive-member 9 that connects successively.
Wherein, with reference to Fig. 4, bleeder circuit 81 comprises capacitor C 1, resistance R 2 and resistance R 1, is connected with resistance R 1 after capacitor C 1 and resistance R 2 parallel connections again.Capacitor C 1 plays the dividing potential drop effect in circuit, the voltage that is added on the rectification circuit 82 is reduced, but does not consume the active power in the circuit; With capacitor C 1 parallel resistor R2, the electric charge that stores on capacitor C 1 after the outage is by resistance R 2 discharges, in case hit the people, resistance R 1 plays metering function.
Constant-current device 83 is polar capacitor C2, its anodal dc power anode that connects, negative pole connects dc power cathode, because through the voltage waveform after rectification circuit 82 rectifications is not desirable constant pressure source, but zigzag, polar capacitor C2 charging when supply voltage is higher than capacitance voltage is when voltage is lower than capacitance voltage, the circuit of polar capacitor C2 and back constitutes the loop discharge, is equivalent to constant-current source.
When not having light, photo resistance GL dark resistance as photosensitive-member is very big, be equivalent to open circuit, with the resistance R 3 of its series connection because resistance is relative and photo resistance GL little, so supply voltage almost all is added in the two ends of photo resistance GL, voltage is almost 0 on the resistance R 3, and the voltage that adds on the triode Q base stage is provided by resistance R 3, so the time triode Q end; The voltage at led circuit 5 two ends is supply voltage no better than, and voltage-stabiliser tube DZ conducting constitutes loop, LED luminous lighting.
On the contrary, when illumination, photo resistance GL resistance decreasing, the voltage that is added on the resistance R 3 also increases, and promptly the base voltage of triode Q is also increasing gradually, reaches the turn-on condition of triode Q, triode Q conducting, less than voltage-stabiliser tube DZ conducting voltage, triode Q can be similar to and regard short circuit as because the voltage that is added on the triode Q is very little this moment, the voltage that is added in illuminating lamp 7 two ends also is approximately zero, voltage-stabiliser tube DZ ends, and lighting circuit is disconnected, and LED is not luminous.
Sensitive illuminance of the present utility model system can select to use or stop using as required.Fig. 2 is the switch connection layout of the utility model embodiment.
When switch 11 was in the S1 position, main lamp body 4 was luminous, did not need this moment the illuminating lamp in the clock and watch just can see the time clearly; When switch 5 was in the S2 position, circuit was unsettled; When switch 5 was in the S3 position, clock and watch intraoral illumination lamp was in running order, throws light on automatically when light is dark.
Certainly; photo resistance GL also can change light sensor or photodiode into; illuminating lamp can be a miniature bulb; above illumination control apparatus is a preferred example of the present utility model; can not limit the scope of the design's innovation and creation; so long as the equalization of doing according to protection domain of the present utility model changes and modify and use, all still belong in the scope that the design contains.
