Abstract
The utility model provides a light-operated LED night light with switchable light sources, and relates to an auxiliary lighting fitting. Provided is the light-operated LED night light with switchable light sources, and light color and luminance of the light can be switched at will. The LED night light is provided with a power circuit, a light-operated circuit, and a light source switching circuit. An input end of the power circuit is externally connected with a power supply, and an output end of the power circuit is connected with a power terminal of the light-operated circuit. An output end of the light-operated circuit is connected with a power terminal of the light source switching circuit. When the night light is used, a light source selector switch is turned, and favorite light color and luminance are chosen, and then a plug is plugged into an electric supply socket. After dark, the light-operated circuit output end is on high potential, and the LED light is lightened. At daybreak, the light-operated circuit output end is on low potential, and the LED light is turned off. Compared with a conventional night light, the night light is advantaged in that light color and luminance are adjustable, the night light can be turned on and turned off automatically, and the night light is easy to use and low in cost.
Description
Technical field
The utility model relates to a kind of assisted illuminating lamp, especially relates to a kind of light-operated LED mini light night of switchable light source.
Background technology
Existing LED mini light night adopts hand control switch lamp conventionally, and the color of light and brightness are all fixing nonadjustable; And the mini light night of conduct sleep floor light, its light color and brightness but vary with each individual, and even same person also can be different to the requirement of light color and brightness in Various Seasonal, and existing mini light night cannot meet the demand of above personalization.
Summary of the invention
The purpose of this utility model is to provide a kind of light-operated LED mini light night of switchable light source, and the light color of this lamp and brightness can arbitrarily be switched.
The utility model is provided with power circuit, light-operated circuit and light source commutation circuit; The external power supply of input of described power circuit, the output of power circuit connects the power end of light-operated circuit, and the output of light-operated circuit connects the power end of light source commutation circuit.
During use, first stir the light source diverter switch at the utility model back side, select light color and the brightness of oneself hobby, then plug of the present utility model is inserted to commercial power socket.When at dark, light-operated circuit output high potential, LED lamp is lighted; When at day, light-operated circuit output electronegative potential, LED lamp extinguishes.Compare with traditional mini light night, the utlity model has that light color and brightness are adjustable, the advantage such as automatic switch, easy to use and cost are low.
Accompanying drawing explanation
Fig. 1 is the structure compositional block diagram of the utility model embodiment.
Fig. 2 is the electric circuit constitute schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, the utility model embodiment is provided with power circuit 11, light-operated circuit 12 and light source commutation circuit 13.The input external power supply AC220V of power circuit 11, the output of power circuit 11 connects the power end of light-operated circuit 12, and the output of light-operated circuit 12 connects the power end of light source commutation circuit 13.
Fig. 2 provides the electric circuit constitute schematic diagram of the utility model embodiment, and in Fig. 2, photo resistance R3, triode Q1, resistance R 4 and voltage stabilizing didoe D5 form light-operated circuit 12; Diverter switch S1, LED luminous tube D6, D7, D8, D9 and resistance R 5, R6 form light source commutation circuit 13.When at dark, photo resistance R3 is reduced by light, and resistance increases, triode Q1 cut-off, and triode Q1 current collection is high level very, voltage stabilizing didoe D5 conducting, LED lamp is lighted.When at day, photo resistance R3 is increased by light, and resistance reduces, triode Q1 conducting, and triode Q1 current collection is low level very, voltage stabilizing didoe D5 cut-off, LED lamp extinguishes.When switch S 1 switches to 1 grade, D6 sends strong ruddiness; When switch S 1 switches to 2 grades, D7 sends weak ruddiness; When switch S 1 switches to 3 grades, D8 sends strong white light; When switch S 1 switches to 4 grades, D9 sends weak white light.The luminous tube that increases diverter switch gear and different colours can form the light source of various different colours and different brightness.Power circuit 11 adopts capacitor C 1 step-down to form by rectification circuit (being comprised of diode D1, D2, D3, D4), filter circuit (capacitor C 2).
Below provide the reference model of each main devices in Fig. 2 and the reference parameter of element.
Triode Q1: low-power transistor S9013;
Diode D1～D4: rectifier diode IN4007; D5:5V voltage stabilizing didoe; D6, D7: red light-emitting pipe; D8, D9: white-light emitting pipe;
Resistance R 3: photo resistance CdS5539, R1:150 Ω, R2:270K Ω, R4:510K Ω, R5, R6:470 Ω;
Capacitor C 1:CBB21-224/400V, C2:100 μ F/16V.
