Abstract
The invention discloses an environmental outdoor LED fluorescent display screen comprising a box. The box comprises a plurality of modules. Each module comprises an LED lamp surface and a control element surface. A hood covers each LED lamp surface of each module. Steady-persistence fluorescent powder layers are formed on the outer surfaces of the hoods in a partial or whole manner and excited by light rays emitted from LED lamps to light. A transparent anti-radiation layer is formed on each steady-persistence fluorescent powder layer and totally covers the same. Thus material of the fluorescent powder layers cannot volatilize in the air, environment pollution factors are reduced, and meanwhile the transparent layers do not affect lighting degree of the fluorescent layers.
Description
Technical field
The invention belongs to electronics applications field, be specifically related to a kind of outdoor environmental protection LED fluorescent display screen.
Background technology
Along with the development of LED industry, market also gets more and more to the demand of LED display kind, and the type of LED display is also more and more abundanter, while achieving basic function, each producer increases some bright spots always on oneself product, expands the market competitiveness and market share.
The patent of invention of " a kind of outdoor LED display screen " of Shenzhen Leden Science and Technology Co., Ltd.'s application on March 14th, 2014, application number is 201410096507.1, the patent application disclose a kind of outdoor LED display with long afterglow fluorescence coating, the long-afterglow fluorescent bisque that the light that the outside surface local of face shield or be all provided with can send by LED luminescence unit excites, after closing display screen at night, because the fluorescent powder of long-afterglow fluorescent bisque was subject to exciting of LED luminescence unit and luminous before display screen extinguishes, after LED luminescence unit extinguishes, because the general residing environment of LED display is comparatively dark, therefore, accordingly, the pattern or the word that still remain with certain time length in appearance of screen, for street, on road, institute passer-by views and admires, continue the effect playing advertisement, although this display screen can continue to present display effect after closedown, but, also there is certain drawback, especially fluorescence coating material radiation, very important on the impact of environment.
Fluorescent powder (being commonly called as luminescent powder), is divided into photo-induced energy storage luminescent powder and active luminescent powder two class of band usually.Photo-induced energy storage luminescent powder is that fluorescent powder is after being subject to the irradiations such as natural light, daylight light, ultraviolet light, luminous energy is stored, after stopping illumination being penetrated, discharge in the mode lentamente with fluorescence, so at night or dark place, still can see luminescence, the duration reaches several little of tens hours.Being with active luminescent powder, is mix radiomaterial in fluorescent powder, the rays excite light-emitting phosphor utilizing radiomaterial constantly to send, and this kind of luminescent powder fluorescent lifetime is very long, but because poisonous and harmful and environmental pollution etc., so range of application is little.
People utilize the long-time luminous characteristic of luminescent powder in real life, make weak illumination light source, special use is had in military service, this material is coated in various switch sign on instrument, clock and watch, window, machine, the places such as the handle of door, also can be pressed into various symbol, parts, articles for use (as power switch, socket, fishhook etc.) with various light-passing plastic together.These luminous components, after illumination is penetrated, to be got up etc. it still at continuous illumination, are made people can distinguish peripheral direction, for work and life bring convenience after night or accidental power failure, lightning.Noctilucent material ultrafine particle is mixed in textile, makes color more bright-coloured, child puts on the textile of noctilucence, can reduce traffic hazard.
At present both at home and abroad Noctilucent material is mainly with ZnS(zinc sulphide), SrS(air bag system) and CaS((Column Address Strobe) write a Chinese character in simplified form) make, send green glow and gold-tinted.But the easy deliquescence of SrS, CaS material, brings difficulty to widespread use.So market is mainly the Noctilucent material of matrix with ZnS.But its after time only has 1 ~ 3 hour, and in high light (as sunshine), ultraviolet light and humid air blackout apt to deteriorate, so in a lot of fields in application be restricted.Although interpolation is bored, copper coactivated ZnS luminescent powder has very long after time, it has infrared quenching phenomenon, and under electric light light (comprising more ruddiness) irradiates, twilight sunset is extinguished very soon.
Although fluorescent powder has much many, there is maximum drawback is exactly, and after the volatilization of most of fluorescent powder, can produce environmental pollution, and reducing environmental pollution is social problem demanding prompt solution instantly.
