Description
Technical field
The utility model relates to field of LED display, particularly relates to convertible LED display.
Background technology
Along with China's rapid development of economy, China's outdoor advertising industry enters the optimized development stage, and science and technology has become the coat that outdoor information transmitting carrier constantly converts.As " convertible LED display " (comprising: LED turns on two sides display screen, display screen, LED overturn screen etc. are turned in LED tri-face), it is demand according to modern city energy-saving and emission-reduction and the information platform of a kind of low-carbon (LC) be born, low-power consumption, high benefit.Existing " convertible LED display " structure, one " triangle LED module " is formed by triangular pipe and LED display module, this " triangle LED module ", in three display surfaces of triangular pipe, wherein two faces are for pasting air brushing picture, also have a face to be provided with LED display module; Described " triangle LED module " is arranged in a large display surface by vertical direction is regular, and is provided with Decorative frame in surrounding.Described " 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.This " convertible LED display " is that can show the description picture of two sides cyclical variations daytime, can play lively video information or photoelectricity landscape effect in the evening by " LED display " the evolution carrier with " three faces are turned over ".It takes full advantage of lamp by day, and the brightness ratio playing video at night is lower, and therefore, " convertible LED display " is a kind of energy-efficient information platform.
Above-described " triangle LED module " is " convertible LED display " core building block, the video pictures that the no matter description picture of daytime shows, or evening is shown, is all realized by " triangle LED module ".Because " convertible LED display " is mainly used in outdoor environment, therefore, for " triangle LED module ", " waterproof and dustproof " is crucial, is also one and more difficultly deals with problems.
Occur in existing product " triangle LED module " that many structures are different.
Example one: Chinese utility model patent ublic specification of application CN201662956U discloses one " LED turns on two sides the LED panel structural improvement of billboard ", it comprises LED panel, this LED panel is connected and composed by multiple LED panel unit, each LED panel unit is provided with the clear hollow convex body corresponding with LED, described LED panel is pasted with waterproofing membrane unit, this waterproofing membrane unit is provided with the through hole corresponding with clear hollow convex body, the groove sealing that the length that the length of described waterproofing membrane unit is greater than LED panel unit will be formed between two adjacent LED panel units.This structure, is the groove sealing being pasted with waterproofing membrane unit and being formed between two adjacent LED panel unit in described LED panel (this LED panel is also called " LED display unit "), realizes waterproof object like this.
Example two: Chinese invention patent application prospectus CN103413505A discloses one " LED tri-face with guard shield is turned over ", it comprises triangular pipe, one of them face of triangular pipe is installed with LED module fixed head, LED is installed with outside LED module fixed head, transparent shroud plate is snapped with outside LED module fixed head, it is inboard that LED is positioned at transparent shroud plate, and transparent shroud plate is along the elongated setting of length of triangular pipe.This case also uses transparent shroud plate and protects LED, achieves the waterproof to LED, but also at transparent face mask surface coverage advertisement poster.
Example three: Chinese invention patent application prospectus CN102750883B discloses " advertisement board structure is turned on a kind of LED two sides ", it comprises triangular prism two sides and turns over aluminium section bar, be arranged at two sides and turn over pcb board on aluminium section bar one side, described pcb board is evenly distributed with a plurality of LED, described pcb board is provided with independently of each other a plurality of independent lamp holder for each LED of cover cap, two other side of intersecting of aluminium section bar is turned on described two sides has extension edge along the opening direction of angle is extended, described extension edge, sealant is filled with in the space that pcb board and independent lamp holder surround.This structure adopts in the space that surrounds of a kind of independent lamp holder the layer that is filled with a sealing, and can prevent the problem occurring rainwater leaching when using out of doors, can also enhance productivity meanwhile.
From above-mentioned three patent examples, they carry out protection encapsulation respectively by the structure of the independent lamp holder of a kind of transparent membrane, transparent shroud plate, each LED of cover cap, effectively can protect LED panel unit like this, it is a kind of good scheme, wherein example three " advertisement board structure is turned on a kind of LED two sides " is filled with a sealing layer in the space that extension edge, pcb board and independent lamp holder surround, and also improves production efficiency like this.But in the said goods, have employed transparent membrane, transparent shroud plate, transparent shroud plate covering LED safeguard procedures respectively, like this, one is the heat radiation that can affect LED; Two be can because of distortion, variable color, make moist and affect display effect; Three is only carried out safeguard procedures to LED lamp tube, other electronic devices and components of LED display unit are not effectively protected, therefore outside above-mentioned safeguard procedures, also need the protective treatment carrying out other structure, so just make troubles to installation and maintenance maintenance.
