LED lamp string display screen
The present invention relates to a kind of display screen, particularly LED display.
Along with the development of science and technology, the technology of LED display screen and industry have all obtained significant progress.As one of important present information release vehicle, LED display screen is widely used in fields such as physical culture, traffic, civil aviaton, finance, medical treatment, education, industry, bank, security, communication, communications and transportation, Industry Control, media advertising, labour market, the industrial and commercial tax, technical supervision harbours, for information issue and the information service of all trades and professions are offered help.
At present, the LED display screen that industry is popular is mainly formed by multiple box body splicings, casing is formed by each module group assembling again, wherein module is made up of drain pan, face shield, PCB lamp plate and drive plate again substantially, then adds that special display driver circuit, D.C. regulated power supply, software, framework and outer decoration form whole display screen.This series products framework cost is higher, site operation complexity, and product maintenance maintenance difficulty, holistic cost is higher; As the client's (general main display text and simple micro-mark) for using small-sized screen display screen, especially for the variable information display screen of traffic control, existing LED display screen does not have advantage on cost.In prior art, for cost-saving, normally multiple lamp pearls are composed in series to the display screen pattern of pattern, but because lamp pearl is to be all fixedly mounted on pcb board, and this pcb board matches with the demonstration size of pattern again, not only take place, and in the time will changing pattern, must change corresponding pcb board, and because lamp pearl is to be welded on pcb board, can not reuse, cause great inconvenience and waste.
Summary of the invention
The technical problem to be solved in the present invention is: the LED display that a kind of pattern of independent assortment is quickly and easily provided.
The solution that the present invention solves its technical matters is: LED lamp string display screen, comprise face shield, lamp band, lens corresponding with light-emitting component on lamp band, also comprise lens mount, the convex lens that described lens comprise light-guiding pillar, are connected with light-guiding pillar, described light-guiding pillar is near described light-emitting component; Described lens mount is the casing of two ends hollow, described lens are fixedly mounted in lens mount, the upper surface of convex lens is above the upper surface of lens mount, described lens mount lower surface and the releasable connection of lamp band, described lens mount lower end is also provided with the cover plate being flexibly connected with lens mount, described cover plate is provided with draw-in groove, and the sidewall outer face of lens mount is provided with the projection coordinating with cover plate draw-in groove, and described cover plate covers lamp band and is connected with lens mount sidewall; Described face shield is provided with multiple for the hard-wired through hole of lens mount, and multiple through holes can freely form multiple patterns.In the time that needs show certain specific pattern, the light-emitting component of lamp band is arranged on to the position of corresponding through hole by filling lensed lens mount, when light-emitting component energising, rays pass through lens passes, the lens of lighting are thus combined into required pattern on face shield, in the time that needs are changed pattern, only need lens unit to pull down, install by new arranged in patterns mode, because lamp band has flexibility, random light-emitting component is installed according to the position of face shield through hole of energy, has saved PCB board structure of circuit.
As the further improvement of technique scheme, the lower surface of the sidewall of described lens mount is provided with salient point, and described lamp band is provided with the circular hole corresponding with described salient point.
As the further improvement of technique scheme, described lamp is with many.
As the further improvement of technique scheme, described lens mount is plastic member, and cover plate and lens mount are one-body molded, and cover plate is connected with a wherein sidewall of lens mount.
As the further improvement of technique scheme, described light-guiding pillar and convex lens are one-body molded, and described lens are fixedly connected with lens mount by buckle mode, between convex lens and lens mount upper surface, are also provided with an O-ring seal.
The invention has the beneficial effects as follows: utilize flexible lamp band lamp pearl to be arranged on the correspondence position of face shield, form required pattern by lamp pearl, and lamp band is installed by removable lens combination, in the time that needs are changed pattern, lens and lamp band are separated, then the lamp pearl of lamp band is arranged on new position, forms new pattern.The LED lamp string display screen forming therefrom, flexibly, conveniently, and cost is low.
