Abstract

The utility model relates to an aluminium electroluminescence device which comprises a base plate, a luminescent layer, a light reflecting layer, a transparent conducting layer and a protective layer, wherein inorganic luminescent powder and organic medium mixture are printed on the base plate to form the luminescent layer; tin or indium is plated on the luminescent layer to form the transparent conducting layer; the light reflecting layer is arranged on the transparent conducting layer, and a transparent film with high ultraviolet resistance is stuck on the transparent conducting layer. The aluminium electroluminescent device has the advantages of stable performance, less power consumption, light weight, long service life and high brightness. The utility model can emit eye-catching light at night, and has a light-reflecting function at the same time. The utility model can resist the ultraviolet irradiation if the utility model is used in the open air.

Description

The aluminium field light-emitting device

The utility model belongs to electroluminescent device, is specially adapted to license plate for vehicle, traffic route sign board and significantly advertisement.

Electroluminescence is divided into inorganics electroluminescence and organic el, and luminescence mechanism all is under electric field action, energy takes place shift, and makes inorganic or organic luminescent substance produce the visible light of different wave length according to different molecular structures and external electrical field condition.Inorganics illuminating AC power produces electric field, and relative voltage is higher, and the brightness of luminescent device is directly proportional with alternating voltage and oscillation frequency within the specific limits, and organism illuminating direct supply produces electric field, and relative voltage is lower.Luminous and the luminous surface cold light source that all belongs to of organism of inorganics.

The field that electroluminescent material is used is very wide, and luminescent device is of a great variety, and glass luminescent device, plastics luminescent device, vitrified enamel optical device etc. are arranged.

License plate for vehicle, road and traffic sign plates, building word mark board that China is existing, major part has passive lighting function, can not active illuminating, not eye-catching at night, be unfavorable for the traffic administration and the security administration at night.

The purpose of this utility model is exactly to overcome the shortcoming that above-mentioned existing label can not active illuminating, overcoming various electroluminescent devices does not simultaneously have the shortcoming of passive reflection function, invent a kind of aluminium field luminescent device, this device also has passive reflection function except that having the active illuminating function.

The utility model relates to a kind of aluminium field light-emitting device; comprise that substrate, luminescent layer, transparency conducting layer, reflector layer, protective seam, inverter, power supply is characterized in that being printed on the substrate inorganic light-emitting powder and organic media potpourri; form luminescent layer; on its luminescent layer, be coated with tin or indium; form transparency conducting layer, the brushing reflectorised paint is made reflector layer and is posted the high transparent membrane of antiultraviolet on transparency conducting layer.

The stable performance of aluminium matter luminescent device, power consumption is minimum, in light weight, the life-span is long, brightness is strong, and noctilucence is very eye-catching, simultaneously, also has reflection function.This luminescent device is used in the open, can ultraviolet radiation resisting.

Fig. 1 is aluminium field light-emitting device figure, below in conjunction with accompanying drawing this utility model is described in detail

1. use aluminium alloy plate as base stage 1, inorganic light-emitting powder and organic media mixing back are imprinted on the substrate 1 with screen printing technique, form luminescent layer 2.

2. make transparency conducting layer 3 on luminescent layer 2, its method has two kinds, and a kind of is to use vacuum vapour deposition, and tin or indium evaporation on the surface of luminescent layer 2, are formed transparency conducting layer 3, and another kind is directly to paste transparent conductive film on luminescent layer 2.

3. the brushing reflectorised paint is made organic reflector layer 4 on transparency conducting layer 3, and this reflector layer is with serigraphy or electrostatic coating method, the label remainder except that font or pattern is carried out reflectorised paint block.

4. on reflector layer 4, paste the high transparent membrane 5 of antiultraviolet, do anti-aging and handle.

5. on substrate 1 and transparency conducting layer 3, amplexiform electrode respectively, and draw wiring with conducting resinl.

6. tow sides spraying or the brushing transparent protective film 6,7 at device carries out protection against the tide, insulation processing.

7. the arrangement electrode is installed screw insulation sleeve and bound edge, whole completing.

8. installation inverter, 12V direct supply 9 is become can be for luminous high pressure, the high-frequency ac power device of aluminium matter luminescent device, two electrodes that the aluminium field luminescent device is drawn are connected on respectively on two output terminals of inverter 8, the both positive and negative polarity of 12V direct supply is connected on two positive-negative input ends of inverter 8 respectively, can finishes the normally luminous of aluminium electroluminescence device.
