Abstract

The utility model discloses a LED lantern including a lantern body and a light source. The utility model is characterized in that the light source is an irradiation array formed by a plurality of LEDs. The irradiation array is welded on a circuit board of a plane and is arranged at the upper end and/or the lower end of the internal side of the lantern. As the electricity consumption of the LED is little, the LED can adopt two kinds of drive forms; one is the direct current provided by an ordinary dry cell or an accumulator; the other kind is the alternating current of 220v or 110v. When the lantern is lifted for use, the LED is driven by cells so as to irradiate the lantern. As the utility model is supplied by low voltage, no electricity shock accidents occur, the utility model is very safe to use by lifting by hand. Using the LED as the light source, the utility model not only has high brightness, but also saves more energy and is more environment protective than an incandescent bulb and a power saving fluorescent lamp.

Description

The LED lantern

Technical field

Light fixture, especially lantern that the utility model relates to a kind of illumination and decorates.

Background technology

Lantern generally comprises the lantern frame, shrouds and light source as a kind of conventional lamp of the Chinese nation, can carry and can hang.Carry and to make mobile illuminating lamp; Extension is a kind of celebrating ornament, usually is the top that hangs over the doorway.Light source is candle or the oil lamp of lighting in the previous lantern, and the time of not only lighting is not long, and the shell of the lantern that also ignites easily is dangerous.Now people are everlasting and a lamp holder are installed in the middle of the lantern, load onto bulb or fluorescent tube, with the light source of civil power as lantern.Because heating was bigger when incandescent light bulb and power saving fluorescent lamps were lighted, so the top and the bottom of lantern shell central authorities all have opening usually, so that heat radiation.This lantern of receiving civil power can only fixedly mount, and be inconvenient to carry a lantern move use, and power consumption is big.Also useful dry cell drives the removable lantern that bulb is lighted.But because the bulb power consumption is more, brightness is not high, and practicality is bad.

Semiconductor technology is just breeding a new revolution---the illumination revolution.Along with the appearance of third generation semi-conducting material gallium nitride, the semiconductor technology forward mankind devote another achievement: with solid-state illumination---the semiconductor lamp (LED lamp) of semiconductor light-emitting-diode (LED) as new light sources.The LED light fixture has the characteristics of power consumptive province, is fit to make energy-saving lamp and uses.Caloric value was very little when low-power LED was lighted, and had both made the lamp outer casing of making near combustible also can not cause burning.LED forms with epoxy resin enclosed, than incandescent lamp bulb or the power saving fluorescent lamps sound construction made with glass, shock resistance, vibration resistance.LED is stable and reliable for performance in addition, and is in light weight, the characteristics that volume is little.Can be made into light and handy durable light source.The life-span of LED reaches tens thousand of hours, and the light fixture of making can use for a long time, is real green light source.

The utility model content

This practical purpose provides a kind of LED lantern, should be able to solve that the power consumption of above-mentioned existing lantern light source is big, brightness is low and unsafe problem.

The new technical scheme of this practicality is:

A kind of LED lantern, it comprises lantern body and light source, it is characterized in that:

The light emitting array of described light source for being made of a plurality of LEDs, this light emitting array is welded on the circuit board on a plane, is arranged on the upper end and/or the lower end of lantern body inboard.

Adopt the light source of LED, just can solve all drawbacks of lantern light source in the past as lantern.Caloric value was very little when LED was luminous, so can not stay louvre on the lantern shell, made case type.Surface temperature was low when LED was luminous, had both made the lantern shell of making near combustible also can not cause the lantern burning, and security is good.LED is very light and handy again, can make light and handy lantern, is well suited for carrying and uses.With the epoxy resin enclosed LED sound construction that forms, shock resistance.Even the lantern overturning is fallen, the LED that is contained in the lantern also is not easy to damage.LED-based just above characteristics can fuse circuit board that led array has been installed and lantern shell, make the lantern with the LED illumination.

Because the power consumption of LED is very little, so LED can adopt two kinds of drive forms, a kind of is the direct current that provides with general dry battery or rechargeable battery, and another kind is the alternating current of 220 volts or 110 volts.When lantern is being proposed use, use the battery driving LED, illuminate lantern.Because be low-voltage DC supply, the casualty accident that can not get an electric shock, portable use is fool proof.When lantern is hung up use, through Switching Power Supply rear drive LED, provide light source to lantern with alternating current.Make light source with LED, brightness height not only, and also more energy-conservation than incandescent lamp bulb and power saving fluorescent lamps, environmental protection.

Description of drawings

Fig. 1 is a perspective structure diagrammatic sketch of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is the perspective structure schematic diagram of the utility model LED lantern.In Fig. 1, lantern body 1, it comprises the lantern frame and shrouds, and wherein, shrouds generally and is made by silk, plastics or the paper of red or other color; Lead 2 between the upper and lower circuit plate; Dc source interface 3; Switching Power Supply 4; LED 5; Circuit board 6; AC power interface 7.Wherein, be welded with the light emitting array that LED 5 constitutes on the circuit board 6, constitute light source, this circuit board 6 that is welded with LED be arranged on lantern body 1 inboard the upper end and or the lower end, constitute the LED lantern.Expressed the structure that light source is located at cage body 1 inner top side and lower end in the drawings, apparent, under the enough situation of brightness, if be located at the upper end respectively separately or the lower end is fine.It is dc source interfaces 3 of directly guiding on the circuit board 6 that two kinds of power input interfaces 3 of AC and DC and 7, one are arranged on the circuit board 6, and dc source is provided by external dry cell or rechargeable battery.Another is an AC power interface 7 of guiding to the AC-powered of on the Switching Power Supply 4 220 volts or 110 volts.The alternating current that Switching Power Supply 4 attracts AC power interface 7 is through providing galvanic current to circuit board 6 behind rectifying and wave-filtering and the current stabilization.Circuit board 6 power supplies in order to give the lower end are provided with lead 2 between the upper and lower circuit plate.Described LED lantern adopt interchange and or two kinds of power supplys power supplies of direct current.In order to make the lantern color bright-coloured more attractive in appearance, adopting the LED identical or close with lantern cover color is light source, and for example, red lantern adopts red LED.Certainly, the color of lantern cover also has other color, as green, yellow, orange etc., also can adopt the LED of corresponding glow color.
