Description

The convertible LED display of a kind of superelevation
Technical field
The utility model relates to field of LED display, particularly relates to convertible LED display.
Background technology
Building in the livable process in city, China's outdoor advertising industry enters the optimized development stage, and science and technology has become in today the coat that outdoor information transmitting carrier constantly converts.Face day by day deficient at the energy, environmental pollution is day by day serious, today that government advocates energetically " energy-saving and emission-reduction ", a kind of " convertible LED display equipment " (as LED two sides turn over, LED tri-face is turned over, LED overturn screen etc.), a kind of low-carbon (LC) that it is demand according to modern city energy-saving and emission-reduction and is born, low-power consumption, high benefit are as information communication platform.This " convertible LED display equipment " is by " LED display " the evolution carrier with " three faces are turned over ", the description picture of two sides cyclical variations can be shown daytime, can be play lively video information or photoelectricity landscape effect in the evening, therefore, it with make full use of daytime lamp, night showing luminance be only 800-1800CD/ ㎡, photoelectricity reproduction time is only the mode of operation at night and realizes energy-saving effect.Like this, not only solve the many disadvantages of existing numerical information platform and billboard existence, and summarize the advantage of existing numerical information platform and billboard media.
Existing " convertible LED display equipment " structure, in a kind of three faces of rectangular triangular prism, there are two faces for pasting air brushing picture, one is had to be with the face of groove to be provided with LED display module, triangular end cover is provided with at the upper and lower port of triangular prism, form a kind of triangle LED module, this triangle LED module is by vertical direction regular arrangement display surface, and be provided with Decorative frame in surrounding, triangle LED module upper end is connected with the upper positioning beam doubling as Decorative frame, lower end is connected with the underdrive beam doubling as Decorative frame, by the Pattern Reversal of setting under power system drives, realize many changing pictures, be linked into power distribution system completely by civil power, this distribution system average mark is made into multiple-channel output and provides AC power to multiple switch power supply system, because the space of triangle LED module inner chamber is very little, it is outside that Switching Power Supply and receiving system are all arranged on triangle module, and the information of triangle LED module leads to outside from upper end cover through upper locating device with power circuit and is connected with switch power supply system and receiving system.Because the length of current triangular prism is no longer than 8 meters, therefore, the height of existing " convertible LED display equipment " is also only for 8 meters.Along with socioeconomic fast development, skyscraper is as rising sheer from level ground as emerging rapidly in large numbersBamboo shoots after a spring rain, as " the convertible LED display equipment " of serving modern city, one of indispensable key factor of reflection modern city mental outlook, this " convertible LED display equipment " highly can not meet the growth requirement of modern city.
In order to make " convertible LED display equipment " " obey, serve Urban style and urban whole planning " better, also need to be improved at height design aspect.In recent years, occurred that advertisement board triangular prism is doubled on a kind of superelevation LED two sides.
Example one: Chinese utility model patent ublic specification of application CN102013221B discloses one " superelevation LED doubles advertisement board triangular prism in two sides ", it is being fixedly connected with by a bindiny mechanism with the second triangular prism bottom end cover at the first triangular prism upper end cover; This bindiny mechanism is that the perforate of being inserted in the middle part of bottom end cover by the connecting rod on upper end cover is fixedly connected with; This connecting rod is connecting rod; The polarizing slot on connecting rod top inserts the locating convex block of perforate, and connecting rod is a sheathed arm-tie also, and this arm-tie is fixedly connected with advertising framework; Be provided with the clutch shaft bearing be installed on connecting rod in arm-tie bottom, arm-tie bottom is also provided with the second bearing be installed on connecting rod; From this patent, said structure utilizes connecting rod by wire by upper and lower signal communication.
Example two: Chinese utility model patent ublic specification of application CN202871212U discloses one " via hole type dustproof and waterproof LED tri-turns over ultrahigh connection in face ", this web member is provided with a band keyway hollow metal axle, and circuit passes from band keyway hollow metal axle inside.
Example three: Chinese utility model patent ublic specification of application CN103560369A discloses one " superelevation LED overturn screen signal connector ", it comprises lower triangle joint device with upper triangle joint device and is screwed into an entirety; At connector female seat upper cover and the power plug string holes, 20 signal pin holes and three screw holes in triangle distribution that are covered with three arcs that position coincide corresponding under connector female seat and arrange; This structure, be also by connector by upper and lower signal be communicated with.
Above-mentioned three patent examples, can realize " convertible LED display equipment " by upper and lower signal and the structure be communicated with and connect height.Because the load capacity of LED display receiving card is limited, (that is, counting of the pixel that LED display receiving card can control is limited, usually the resolution of individual receiving card is 512 × 256), if control pixel to have exceeded range of control or input signal and load apart from oversize, its signal level can increase with control pixel or transmission line increases and decays, and causes refreshing frequency to decline even out of control; In addition, along with screen body increases, its direct current supply electric current, along with increase, brings difficulty to supply line like this, and thus, above-described three patent examples, can realize the height of " convertible LED display equipment " or to connect high-level be limited.
