Description
Technical field
The utility model relates to a kind of Pointing sign boards, more particularly, refer to a kind of long afterglow hair for being used to indicate mark
Electro-optical device.The device can be used in place name instruction, security against fire instruction, advertisement etc..
Background technique
With the rapid development of the energy and the science and technology that shines, people require increasingly the illumination instruction of night trip
Height also increasingly increases the light-emitting function degree of dependence of sign class product.Place name plates, fire-fighting peace including rural streets
The emergency escape mark of full tunnel, trail guide of public place etc. require to increase light-emitting element.
Traditional long-persistence luminous mark is because the luminous material layer of surface screen-printed is relatively thin, and luminescent material can not be grown in addition
Time is always maintained at original intensity, and the duration that shines soon, is difficult to differentiate the instruction content of mark at a distance.In addition simple
Power-type sign because power consumption it is big, be unable to satisfy and long-time power supply light emitting realized by electrical storage device, need to pacify again
During dress it is reserved within the walls or underground electric wire, bring many inconvenience.
System of the LED to circulate on the market at present in conjunction with long afterglow is also more mature, but LED wafer and light guide plate
Design exist in the uses of many fine small marks apparent in the thickness for considerably increasing light emitting device to a certain degree
Defect cannot achieve ultra thin requirements.
Summary of the invention
The purpose of this utility model is to devise a kind of novel long-persistence luminous device for being used to indicate mark.Pass through
EL electric-field luminescent layer and via controller carry out control power-on time to the fluorescent lifetime point of the EL electric-field luminescent layer,
The service life of EL luminescent layer is not only extended, but also energy consumption is extremely low.Electric current needed for required high-frequency and voltage, load
But very small, probable ranges are 0.1~1MA/CM2, in light tiles area less than 10 CM2When, operating current is left in several MA
It is right.A LED is only driven just at least to need the electric current of 10MA compared with LED.Low-power consumption for using battery powered device,
From electrical characteristic, EL light tiles have capacitance-resistance characteristic, and capacitance is usually 2 to 6MF/IN2, and pass through short time EL piece
It shines, inspired long-lasting luminescent layer can make long-persistence luminous layer brightness maintain 2000MCD/CM always2More than, so both
Power saving can maintain the light emission luminance of mark again.The device is ultra-thin simultaneously, can be easily applied in the mark of all kinds of instruction functions.
A kind of long-persistence luminous device being used to indicate mark of the utility model, the device is by photic long-persistence luminous layer
(1), transparent ITO electric layer (2), EL electric-field luminescent layer (3), insulating layer (4), back electrode layer (5) and protective layer (6) are constituted；?
It is transparent ITO electric layer (2), EL electric-field luminescent layer from top to bottom between photic long-persistence luminous layer (1) and protective layer (6)
(3), insulating layer (4) and back electrode layer (5).
The long-persistence luminous device of the utility model design be by sign (security against fire prompt information, have it is electric dangerous,
Cell building plate etc.) it is arranged in the outer surface of photic long-persistence luminous layer (1).
Photic long-persistence luminous layer (1) is that alkaline-earth aluminosilicate luminescent powder and resin glue are uniformly mixed in the ratio of 1~2:1
After be coated on transparent ITO electric layer (2) and formed, the thickness of coating is generally 0.5~3mm.
The advantages of one kind of the utility model novel long-persistence luminous device for being used to indicate mark, is:
1. the device does not need LED wafer and light guide plate as excitation-light unit, so that product thickness is thinner, shine more
Uniformly, use is more extensive convenient.Uniform astigmatism, not will cause vision dazzling, be a kind of light source of not nocuity.
2. the device is a kind of short wavelength light, optically focused and penetration power are strong, especially seem bright, eye-catching in night or thick fog.Subtract
That has lacked EL luminescent layer uses the time, improves service life and security performance.
3. the device waterproof heat-resisting, uvioresistant, indoor and outdoor all may be used.Improve shining for simple long-persistence luminous mark
Brightness and technology sense.
4. the device uses the frivolous softness of cold light film, flexible or cut, do not take up space, installation is easy, and can save engineering
Cost.Energy consumption is greatly reduced, the volume of the electric power storages such as capacitor is reduced.
