Above-mentioned Light-operated night lamp wherein, is positioned at the position that can cover transparent region and is provided with guide groove on the described lamp socket, two opposed side edges of described mobile cover are provided with chimb, described chimb is embedded in the described guide groove and moves, and covers or exposes this transparent region, thereby cover or do not cover photo resistance.
Above-mentioned Light-operated night lamp, wherein, described light-operated circuit also comprises a divider resistance, is in series with described photo resistance; Described input is connected with the tie point that described divider resistance and photo resistance are in series.
Above-mentioned Light-operated night lamp, wherein, the amplifier of described light-operated circuit is a dual-stage amplifier.
Above-mentioned Light-operated night lamp, wherein, described power circuit comprises that mainly a bridge rectifier and is connected in parallel on the voltage-stabiliser tube of bridge rectifier output.
Above-mentioned Light-operated night lamp, wherein, described light source is the LED diode lights.
Above-mentioned Light-operated night lamp, wherein, described lampshade is translucent at material, light-permeable.
Above-mentioned Light-operated night lamp, wherein, the material of described lamp socket and mobile cover is opaque.
Because the utility model has adopted above technical scheme, employing increases a light-operated circuit and a power circuit on original mini light night basis, and lamp socket is provided with transparent region, photo resistance is set in it, and be provided with mobile cover thereon, by moving this mobile cover, cover or do not cover photo resistance, reach the purpose that automatic control and Artificial Control mini light night are lighted or closed.
Description of drawings
Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the overall structure schematic diagram of the utility model Light-operated night lamp.
Fig. 2 is the electrical schematic diagram of the embodiment of the power circuit of the utility model Light-operated night lamp and light-operated circuit.
The specific embodiment
See also Fig. 1.The utility model Light-operated night lamp, comprise the light-permeable that constitutes by trnaslucent materials lampshade 1, be located at light source D1 in the lampshade, be used to be provided with the lamp socket 2 of light source, be provided with plug 3 in the bottom of lamp socket.In lamp socket 2, also be provided with a light-operated circuit 6 of mainly forming by photo resistance and amplifier and the power circuit 7 (please cooperate) that is used to described light-operated circuit and light source power supply referring to Fig. 2.Described lamp socket is made of opaque material, which is provided with a transparent region 4, and described photo resistance is positioned at this transparent region 4.On transparent region 4, also be provided with a mobile cover 5 that can cover or expose this transparent region.Be positioned at the position that can cover transparent region on the described lamp socket and be provided with a pair of guide groove, the mobile cover both sides are provided with chimb, and the chimb of mobile cover both sides is embedded in the described guide groove and moves, and cover or expose this transparent region.In the present embodiment owing to be arranged to the top of lamp socket 2 bowl-shape, its oral area cover cap has lampshade 1, for ease of operation and attractive in appearance, the mobile cover of present embodiment adopts rotary, its structure is: be respectively equipped with a guide groove 11,12 in the bottom of lamp socket 2 and the end face of lampshade 1, described mobile cover can partly coat lamp socket and lampshade, two opposed side edges of this mobile cover are provided with chimb 51,52, described chimb is embedded in the described guide groove and moves, cover or expose described transparent region 4, thereby cover or do not cover photo resistance.Described light source D1 is the LED diode lights.
See also Fig. 2.The light-operated circuit 6 of the utility model Light-operated night lamp is mainly formed by photo resistance CDS with by the triode Q1 of two series connection, the amplifier that Q2 constitutes; The photo resistance CDS of described light-operated circuit is arranged in the transparent region of lamp socket, and described mobile cover can cover or not cover photo resistance CDS.
The described light-operated circuit 6 of the utility model Light-operated night lamp also comprises a divider resistance R3, and this divider resistance R3 and described photo resistance CDS are in series, and its tie point connects amplifier input terminal.
The described power circuit 7 of the utility model Light-operated night lamp is used to described light-operated circuit and light source power supply.This power circuit 7 comprises that mainly a bridge rectifier DB and is connected in parallel on the voltage-stabiliser tube D2 of bridge rectifier output.Input at circuit also is connected in series a safety capacitor C.
