Abstract

The utility model relates to an electroluminescence vehicle number plate, comprising a low temperature glass protective layer (1) and a conductive silver (2) which is positioned on the inner side of the protective layer. The lower side of the silver is in sequence coated with a conductive layer of tin tetrachloride (3), a luminescent layer of fluorescent powder (4) and a reflection layer of titanium white (5); the outer side of the reflection layer is provided with a base plate (7); numbers which indicates a vehicle number is arranged on the base plate; the number plate also comprises a traction screw (8) and a porcelain insulating ring (6); one end of the traction screw is connected with an alternating power supply; the other end of the alternating power supply is connected with the conductive layer of tin tetrachloride. The vehicle number plate has no infrared radiation, wide viewing angle, soft light, easy observation, visibility within 1 km, strong adaptability for surrounding environments, firmness and reliability.

Description

Electroluminescence vehicle number plate

The utility model belongs to License Plate, particularly the electroluminescence License Plate.

Existing License Plate itself can not be luminous, to rely on night automobile tail light, headlight to illuminate respectively and be positioned at the tailstock and the preceding number plate of car, this lighting system, the distance that can see license number clearly is less than 20 meters, the rear-end collision accident takes place easily, is unfavorable for traffic hazard detection and traffic administration.Therefore be necessary to provide the License Plate that a kind of visual angle is big, irradiation distance is far away.

The purpose of this utility model provides a kind of License Plate, and this number plate is easily observed, and irradiation distance is far away, and is solid and reliable.

For achieving the above object the utility model by the following technical solutions: number plate comprises: the low temperature glass protective seam; be positioned at the conductive silver of protective seam inboard; scribble the butter of tin conductive layer below the silver successively; the light-emitting phosphor layer, the titanium white reflection horizon is substrate outside the reflection horizon; the numeral that expression vapour license number is arranged on the substrate; number plate also includes and draws nail, porcelain insulating ring, draws nail one termination alternating source, another termination butter of tin conductive layer of alternating source.

Above-mentioned baseplate material has: steel plate, iron plate, aluminium alloy plate, glass etc.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1: electroluminescence License Plate synoptic diagram

The A-A sectional view of Fig. 2: Fig. 1

Among Fig. 1, Fig. 2,1 is the low temperature glass protective seam, and 2 for being positioned at the conductive silver of protective seam inboard; below conductive silver, scribble butter of tin conductive layer 3 successively; light-emitting phosphor layer 4, titanium white reflection horizon 5,7 is a substrate; adopt steel plate; the numeral, Netherlands of expression vapour license number etc. are arranged on the steel plate, and 8 draw nail, 6 porcelain insulating rings; the end and the alternating source that draw nail join, another termination butter of tin conductive layer of alternating source.

Above-mentioned alternating source is oscillator commonly used, and frequency is 200HZ.The power supply of oscillator is 12 volts of the direct currents of automobile storage battery, also can adopt 24 volts of direct currents, adopts when exchanging 220 volts, be through transformer and rectification to 12 volts of direct currents.

Among Fig. 1, the license number color or the background color that show on number plate can be decided as requested, as colored red on substrate, demonstrate redness so, 9 is to fix to use the hole among the figure, is used for number plate is fixed on car the place ahead and car rear, because car the place ahead does not have recessed pockets, so the side of this number plate adds a plate washer, with water-impervious, more reliable performance.

The utility model has the advantages that: adopt the number plate of electroluminescent form, no infrared radiation, the visual angle is big, and light is soft, easily observes, and is as seen, strong to environmental suitability within 1000M, is not afraid of vibration, solid and reliable.
