Abstract
The utility model discloses an LED lamp, which comprises a rectifier, a filtering circuit and an LED lamp group and is characterized in that the LED lamp further comprises a storage battery and a switch, wherein the rectifier is connected with the filtering circuit, the filtering circuit is respectively connected with the storage battery and the LED lamp group, and the storage battery is connected with the LED lamp group through the switch. The LED lamp further comprises a constant-current circuit which is arranged between the filtering circuit and the LED lamp group. The LED lamp disclosed by the utility model can be moved freely and conveniently according to requirements of different using environments and is stable in light-emitting property and better in light-emitting effect.
Description
Technical field
The utility model relates to the LED lighting technical field, is specially a kind of LED lamp.
Background technology
LED has plurality of advantages such as low energy consumption, environmental protection, long service life, just progressively replaces conventional light source with LED as the illuminating product of light source, becomes the solid state lighting electric light source of a new generation.
Tradition LED lighting adopts Fixed Design, and the use of light fixture must be connected in the electrical network, can't move freely according to operating position, has limited the use of LED light fixture; In addition, owing to the influence of electric current to the luminous intensity of LED, when fluctuation took place electric current in the circuit, flicker can appear in the LED light fixture, influenced the illuminating effect of LED light fixture.
The utility model content
For solving the above-mentioned deficiency that exists in the prior art, the purpose of the utility model is to provide a kind of LED lamp, can move freely easily according to the requirement of different environments for use, and luminous stable, illumination effect is better.
For achieving the above object; The utility model is realized through following technical proposals: a kind of LED lamp; Comprise rectifier, filter circuit and LED lamp group, it is characterized in that: said LED lamp also comprises storage battery and switch, and said rectifier is connected with filter circuit; Said filter circuit is connected with storage battery and LED lamp group respectively, and said storage battery is connected with LED lamp group through switch.
In the LED lamp, increase storage battery, light fixture when operate as normal, its external power supply; On the one hand to the power supply of LED lamp group,, make storage battery keep electric energy through rectification, filtered steady direct current on the one hand to charge in batteries; When special circumstances need move to the other places use with light fixture; Can the utility model LED lamp be taken off, to the power supply of LED lamp group, promptly can move freely by storage battery.
As preferably, said storage battery adopts that cost is lower, effect nickel-hydrogen chargeable cell preferably.
In order to realize the stabilized illumination of LED light fixture, reach the better illumination effect.
Said LED lamp also comprises constant-current circuit, and said constant-current circuit is arranged between filter circuit and the LED lamp group.
Constant-current circuit can guarantee the current constant of LED bulb in the LED lamp group; Make that when circuital current fluctuates the electric current of the LED bulb side in the LED lamp group still keeps constant, flicker can not appear in the LED bulb; Guaranteed stable luminous, thereby reach the better illumination effect.
As preferably, the LED bulb in the LED lamp group adopts and is connected in series.
The invention compares that prior art has the following advantages and beneficial effect:
1, through in the LED lamp, increasing storage battery, can move freely easily according to the requirement of different environments for use.
2, before LED lamp group, increase constant-current circuit, make the electric current of the LED bulb side in the LED lamp group keep constant, the LED bulb can flicker not occur with the external current fluctuation, and luminous stable, illuminating effect is better.
