Description

Light emitting diode (LED) sheen lumiline lamp (fluorescent lamp)

Technical field

The present invention relates to a kind of low-voltage direct (or interchange) " light emitting diode (LED) sheen lumiline lamp (fluorescent lamp) " technology, light source adopts light-emitting diodes (LED), outer shape is fluorescent lamp shape (also can large-scale Cylinder type), and luminous fill light belongs to photoelectronics and lighting field.

Background technology

Illumination market adopts common fluorescent lamp (containing electricity-saving lamp) that random corrupted is arranged except that incandescent lamp more at present, influence the life-span, and power consumption is bigger.

On the existing market a kind of fluorescent lamp that makes with light emitting diode is arranged also, but all arrange a string light emitting diode along daylight light inner core, accomplished energy-conservationly, but appearance is luminous not too even, easily finds out the point-source lamp of light emitting diode.

Present technique overcomes above-mentioned shortcoming, and is promptly energy-conservation, luminous soft, long-life, low-voltage advantages such as (getting final product the safe voltage that direct current can exchange again).

The technology of the present invention, adopts and is not used in said structure, but reach above-mentioned advantage as light source with light emitting diode.

Summary of the invention

A kind of soft light emitting diode of the present invention (LED) lumiline lamp (fluorescent lamp) also can be made large-scale garden cylindricality lamp, and a kind of safe low pressure is provided, the lighting engineering of (AC and DC all can, little power consumption, long-life, luminous soft, many color).Because low-power consumption, can with solar cell mutually, make lighting device).

The structure of a kind of light emitting diode of the present invention (LED) sheen lumiline lamp (fluorescent lamp) comprising: the composition diagrams 1 such as pipe cap 5, lead-in wire that weld lighting material layer 4, protection and fixing printed circuit on luminous two printed circuit board (PCB)s 1 that pipe (LED) and resistance combination arranged, light emitting diode 2, good clear tubular bodies 3, the tubular bodies inner-wall spraying and tubular bodies are schematic diagram.

The power supply that light emitting diode adopts can be 3 volts to 48 volts safe voltage (AC and DC all can).

When the light emitting diode electrified light emitting, utilize lighting material that complicated optical principles such as reflection of light, refraction, diffraction are sent soft light, the same like common fluorescent lamp.

Good effect of the present invention and advantage.

1, owing to adopt light emitting diode (LED) as light source, shown in the little electric current of lumiline lamp low-voltage (safe voltage 3V-48V), AC and DC all can, whole low-power consumption.

2, because lighting material is arranged, luminous is soft.

3, the light emitting diode of making now can be accomplished many colors, and can make up additive color control circuit again with three primary colours in a pipe, can realize the conversion of multiple color.

4, can be used for various illuminations.

5, can be used for various decorative lightings (can realize multiple color change).

6, alternative present neon light, even third dimension is more arranged than neon light.

7, adopt and connect and to realize the color post illumination of large cylindrical shape and decorate.

Embodiments of the present invention

Basic structure in a kind of " light emitting diode (LED) sheen lumiline lamp " example comprises: compositions such as glory material layer 4, protection and the fixed printed circuit board on the printed circuit board (PCB) 1 of two ends welding light emitting diode (LED) and resistance combination, light emitting diode 2, good clear tubular bodies 3, the tubular bodies inner-wall spraying and the pipe cap 5 of tubular bodies, lead-in wire; as Fig. 1 schematic diagram, tubular bodies 3 is that wall has the certain thickness hollow transparent body (just the same with common fluorescent lamp housing).

In the another kind of example, on the basis of Fig. 1, apart from certain distance a solid post body (being made by the good transparent material of plastic optical fiber material or other session roads) 6 is installed again in the tubular bodies 3, lighting material is not the inwall that is sprayed on Fig. 1 tubular 3 in this entity, but spraying (or printing) is at the outer surface of solid column type body 6, as Fig. 2 schematic diagram.

In the another kind of example, the solid of Fig. 2 also becomes wall certain thickness hollow pipe body (also being to be made by transparency good plastic optical fiber material or other materials) 7, and lighting material is sprayed on 7 outer surface in this example, as Fig. 3 schematic diagram.

Light emitting diode 2 is single spectrum in a kind of example, examination application scenario and use what monochromatic light surely.

Light emitting diode 2 is white lights in a kind of example, and this is just the same with the general lighting fluorescent lamp.

Light emitting diode 2 can be red, blue, green three primary colours combination in a kind of example, external change color and time control circuit.

In a kind of example, light emitting diode 2 is by promptly there being red, blue, green three primary colours combined chip to have the circuit of control color and conversion time to be enclosed in together again in a shell.

In a kind of example, light emitting diode 2 can be paster when making miniature fluorescent tube.

In a kind of example, tubular bodies 3 just can be with common fluorescent lamp body (shortcoming be perishable, because be that glass is made).

In a kind of example, tubular bodies is with " plastic optical fiber material making ".

In a kind of example, tubular bodies is to make of the good engineering plastics of other transparencies.

In a kind of example, can not be coated with or more scumbling " lighting material " on

tubular bodies

3,6,7 (respectively at Fig. 1,2,3 schematic diagrames) spraying " lighting material " surface, but on the make form dense aperture or dense point of kick or the dense ditch of net form that certain depth is arranged on this surface, also can be effective equally.

Lighting material, available as 8100 series inks etc.

As tubular bodies 3 are common fluorescent tubes of usefulness, the luminescent powder that lighting material also can be used with fluorescent lamp.

Industrial applicibility

Outstanding feature of the present invention is energy-conservation, and many change color are easier than fluorescent lamp, because of fluorescent tube of fluorescent lamp only Can be a kind of color (luminescent powder is determined), our technology can realize the multiple color conversion in a pipe.

The soft degree of light is like fluorescent lamp.

The general 220 volts of alternating currents of fluorescent lamp, our technology can low pressure, and little electric current can be at the safe voltage model Enclose interior design, AC and DC all can.

The neon light that present billboard is used is high pressure, and shortcoming is that the consumption electric energy is big, perishable, the maintenance cost height. This skill Art substitutes neon light, and the large board third dimension can be better than neon light.

Manufacture craft is than fluorescent lamp and the easier realization of neon light.

Present technique can be than neon light and daylight lamp energy-saving more than 80%.

Life-span can arrive 100,000 hours.

Because low-power consumption, can with the supporting lighting device of making of solar cell.

The present technique outstanding feature is that low-power consumption energy-conservation (low-voltage, little electric current) is luminous soft, many colors, the long-life, Environmental protection.

Can and be connected into large-scale Cylinder, use as illumination and decoration. All places that has fluorescent lamp to use can be used, Big shape advertising signboard can substitute neon light.
