Abstract
The utility model discloses a dual-power table lamp which comprises a lamp holder, a lamp arm, a lamp shade, a lamp bulb, a power plug and a power switch. The bottom end of the lamp arm is fixed on the lamp holder, and the lamp shade is fixed on the top end of the lamp arm; the lamp bulb is installed in the lamp shade to be electrically connected with the power plug through a lead, and the power switch is electrically connected onto the lead. The dual-power table lamp is characterized in that a battery box used for holding a direct-current (DC) battery is arranged in the lamp holder, and the DC battery is connected with two ends of the lamp bulb in parallel; the power switch is a single-pole double-throw switch in which two contacts are electrically connected with the power plug and the DC battery respectively, and a switch blade is electrically connected with the lamp bulb. According to the utility model, the dual-power table lamp can be externally connected to an alternating current (AC) power to provide the lamp bulb with working current, and is provided with the DC battery serving as standby power; so that when the power outage occurs, the lamp bulb can be disconnected from the power plug through the knob type single-pole double-throw switch and then to be connected to the DC battery, so as to ensure the table lamp can still work even on a night in the state of power outage.
Description
Technical field
The utility model relates to the small household appliances field, specifically, relates to a kind of dual power supply desk lamp.
Background technology
Desk lamp is the home lighting electrical equipment that people use always, because of its use is comparatively flexible, convenient, and popular to people deeply.Existing desk lamp can only be that bulb provides operating current through external AC power supply, but in daily life, and run into the situation of unexpected power failure through regular meeting evening, and at this moment, existing desk lamp has just lost effect, brings inconvenience to life.Generally, people understand the selected element candle with emergent, but the flame of candle is unstable, is gone out by wind easily, and also fire hazardous has bigger potential safety hazard.
Summary of the invention
The technical problem that the utility model will solve is to overcome above-mentioned defective, and a kind of dual power supply desk lamp that can when having a power failure suddenly, still can be used for throwing light on is provided.
A kind of dual power supply desk lamp comprises lamp socket, arm, lampshade, bulb, attaching plug and power switch, and the bottom of arm is fixed on the lamp socket, and lampshade is fixed on the top of arm; Bulb is installed in the lampshade, is electrically connected with attaching plug through lead, and power switch is connected electrically on the lead, it is characterized in that: be provided with the battery case that is used to hold dc-battery in the said lamp socket, dc-battery is connected in parallel on bulb side; Said power switch is a single-pole double-throw switch (SPDT), and its two contacts are electrically connected with attaching plug, dc-battery respectively, and plug-in strip is electrically connected with bulb.
Say further:
Be connected with dc rectifier between said power switch and the attaching plug.
Said power switch is the knob single-pole double-throw switch (SPDT).
Owing to adopted technique scheme, compared with prior art, the utility model can be that bulb provides the operating current except external AC power supply; Also be provided with dc-battery as stand-by power supply, like this, in case run into the situation of power failure; Can bulb be broken off and being connected of attaching plug through the knob single-pole double-throw switch (SPDT); And be connected dc-battery, to guarantee that desk lamp at the night that has a power failure, can throw light on equally.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
