Abstract
The utility model discloses a portable environment protection energy saving desk lamp, comprising a power supply conversion module, a storage battery and a light emitting diode, wherein the output end of the power supply conversion module is connected with the power supply input end of the storage battery, the power supply output end of the storage battery is connected with the power supply input end of the light emitting diode. The portable environmental protection energy saving desk lamp is simple in structure, employs a 220 V alternating current, and simultaneously uses the 220 V alternating current to charge the storage battery; when the 220 V alternating current is not available, the storage battery can be used as a power supply to provide power for the light emitting diode; and the light emitting diode has a small power, thereby achieving a better energy saving effect.
Description
Technical field
The utility model relates to a kind of desk lamp, particularly a kind of portable environment-friendly and energy-saving desk lamp.
Background technology
At present, the family expenses desk lamp on the market all uses the 220V alternating current, and the power of fluorescent tube is bigger though portable desk lamp uses removable power supply, and power consumption increases and can't use for a long time, the waste electric power resource.
The utility model content
The purpose of the utility model provides a kind of portable environment-friendly and energy-saving desk lamp, can be charge in batteries when using the 220V alternating current, also can use storage battery power supply, has the low characteristics of the little power consumption of power.
The utility model adopts following technical proposals:
A kind of portable environment-friendly and energy-saving desk lamp comprises power transfer module, storage battery and light-emitting diode, and the output of power transfer module connects the power input of storage battery, and the power output end of storage battery connects the power input of light-emitting diode.
Described power transfer module comprises transformer and constant current pressure limiting control circuit, and the output of transformer connects the input of constant current pressure limiting control circuit.
Comprise one or more light-emitting diodes.
Described storage battery is the 6v storage battery.
The utility model is simple in structure, when using the 220v alternating current, is charge in batteries, and in inapplicable 220v alternating current, can adopt storage battery is led powered as power supply.Because the power of light-emitting diode is very little, can reach energy-conservation requirement preferably.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Embodiment
As shown in Figure 1; The utility model comprises power transfer module, storage battery and light-emitting diode; Power transfer module comprises transformer and constant current pressure limiting control circuit, and the input of transformer connects the 220V alternating current, and the output of transformer connects the input of constant current pressure limiting control circuit; The output of constant current pressure limiting control circuit connects the power input of storage battery, and the power output end of storage battery connects the power input of light-emitting diode.Constant current pressure limiting control circuit is a prior art, repeats no more at this.
In the present embodiment, storage battery adopts the 6v storage battery; Can adopt one or more light-emitting diodes according to lighting demand.
The utility model is simple in structure, when using the 220V alternating current, is charge in batteries, and in inapplicable 220v alternating current, can adopt storage battery is led powered as power supply.Because the power of light-emitting diode is very little, can reach energy-conservation requirement preferably.
