The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is included in circuit board 8 is housed in the lamp socket 4, plug 3 is equipped with in lamp socket 4 one sides, light emitting diode 6 on the circuit board 8 exposes lamp socket 4 upper surfaces, there is lampshade 2 light emitting diode 6 outsides, and after the lower end of cosmetic sheet 1 snapped in lamp socket bonnet 5 upper ends, lamp socket bonnet 5 was connected with lamp socket 4 another sides, lamp socket bonnet 5 centers have light-operated induction window 7, and the photo resistance on the circuit board 8 is aligned in light-operated induction window 7.
As shown in Figure 7, described circuit board 8 is formed reduction voltage circuit by being provided with by first resistance R 1 and first capacitor C 1, after forming testing circuit through DB1 bridge rectifier, the filter circuit of pressure-stabilizing of forming by second resistance R 2, second capacitor C 2 and the first voltage-stabiliser tube Z2 with by photo resistance CDS1 and the 3rd resistance R 3 successively, insert and form control circuit by the second voltage-stabiliser tube Z1, triode Q1, the 4th resistance R 4 and LED light emitting diode.
Operation principle of the present utility model:
As shown in Figure 7, on the described circuit board 5, the resistance-capacitance circuit step-down that civil power is formed through first resistance R 1, first capacitor C 1, the filter circuit of pressure-stabilizing that the rectification of DB1 circuit and second resistance R 2, second capacitor C 2, the first voltage-stabiliser tube Z2 form detects, and control and drive circuit provide stablizes level and smooth dc source.Testing circuit is made up of photo resistance CDS1 and the 3rd resistance R 3.The second voltage-stabiliser tube Z1 and triode Q1 form control circuit.When daytime, ambient light was strong, the photo resistance impedance was very little, and the anode potential of the second voltage-stabiliser tube Z1 is higher, and the second voltage-stabiliser tube Z1 and the triode Q1 of control circuit are in cut-off state, and no current flows through light emitting diode (LED); When ambient light deepening at night, photo resistance presents higher resistance, at this moment, the second voltage-stabiliser tube Z1 anode potential is lower, when this current potential satisfies the conducting voltage of the second voltage-stabiliser tube Z1 and triode Q1, control circuit upset, source current makes it luminous by second resistance R 2, triode Q1, the 4th resistance R 4 light emitting diode (LED) of flowing through.Its electric current carries out current limliting by first capacitor C, 1, the first resistance R, 1, the second resistance R, 2, the four resistance R 4, to guarantee light emitting diode (LED) current constant.
