Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention includes top cover 1, rotating shaft 2, lampshade 3, expansion link 4, locator card 5 and base 6, the side of top cover 1 arranges rotating shaft 2, lampshade 3 is connected with top cover 1 by rotating shaft 2, the upper end of expansion link 4 is connected with in the middle part of the lower end of top cover 1, the lower end of expansion link 4 is connected with the upper Middle face of top cover 1, and expansion link 4 arranges locator card 5.
nullAs shown in Figure 2: circuit structure includes the first diode D1 to the 5th diode D5、Bulb H、First resistance R1 to the 3rd resistance R3、Controllable silicon VS、Neon tube N、Electric capacity C、Either-or switch S、Potentiometer RP and photoconductive resistance RG，The live wire of alternating current power supply AC is connected with one end of bulb H，The zero line of alternating current power supply AC is connected with the positive pole of the second diode D2 and the negative pole of the 4th diode D4 simultaneously，The other end of bulb H is connected with the positive pole of the first diode D1 and the negative pole of the 3rd diode D3 simultaneously，The negative pole of the first diode D1 simultaneously with first end of the first resistance R1、The negative pole of the second diode D2 and the positive pole of controllable silicon VS connect，The positive pole of the 3rd diode D3 simultaneously with the positive pole of the 4th diode D4、The negative pole of controllable silicon VS、First end of electric capacity C、First end of the 3rd resistance R3 and first end of photoconductive resistance RG connect，Second end of the first resistance R1 simultaneously with first end of potentiometer RP、The sliding end of potentiometer RP and first end of the second resistance R2 connect，The end that controls of controllable silicon VS is connected with first end of neon tube N，Second end of neon tube N simultaneously with second end of potentiometer RP、The negative pole of the 5th diode D5 and second end of electric capacity C connect，The positive pole of the 5th diode D5 is connected with second end of the second resistance R2 and the center link of either-or switch S simultaneously，First end of either-or switch S is connected with second end of photoconductive resistance RG，Second end of either-or switch S and second end of the 3rd resistance R3 connect.
When either-or switch S is allocated to the position of the 3rd resistance R3, it is a common lamp dimmer.Potentiometer RP, electric capacity C and neon tube N form relaxor, are used for producing pulse-triggered controllable silicon VS.Neon tube N aura conducting voltage is 60-80V, and when electric capacity C is charged to glow voltage, neon tube N aura turns on, and controllable silicon VS is triggered conducting.Regulator potentiometer RP can change electric capacity C charge rate, it is thus possible to change the controllable silicon VS angle of flow, reaches the purpose of light modulation.Second resistance R2, the 3rd resistance R3 are constituted potentiometer and are also charged to electric capacity C by the 5th diode D5, change the second resistance R2, the 3rd resistance R3 dividing potential drop also can change the controllable silicon VS angle of flow, makes the brightness of bulb H change.
When either-or switch S is allocated to the position of photoconductive resistance RG, photoconductive resistance RG replaces the 3rd resistance R3, when ambient light is more weak, photoconductive resistance RG presents high resistance, 5th diode D5 right-hand member current potential raises, and electric capacity C charge rate is accelerated, and frequency of oscillation uprises, the controllable silicon VS angle of flow increases, and bulb H both end voltage raises, highly increases.When ambient light strengthens, photoconductive resistance RG resistance diminishes, contrary to the above, electric light both end voltage step-down, highly reduces.
First diode D1 to the 5th diode D5 model is IN4007, the first resistance R1 is 100 Ω, the second resistance R2 is 400 Ω, the 3rd resistance R3 be 500 Ω, controllable silicon VS model be 2N6565, electric capacity C be 300uf, potentiometer RP is 100K Ω.
