Abstract
The invention discloses an LED display, comprising a module part, a power supply part and a structural part, wherein, the module part adopts a high-voltage low-current transmission mode, and respectively adopts voltage adjustable power supply to the red, green and blue lamp tubes through a differential pressure module; the module of the invention adopts the high-voltage low-current transmission mode, cancels voltage-dividing resistance on a PCB, and respectively supplies power to the red, green and blue lamps, reduces the transmission loss, and reduces heat energy to a large extent; the power supply adopts a newly designed switch power supply, has high efficiency, lower heat, lower energy consumption and intelligent control; aiming to the above characteristics, realizes substantially slimming, ultrathin, partial or whole standardization, universalization and simplification, and meanwhile, the structure design simplifies packing materials and design and lowers transportation cost; and as to the large-scale outdoor screens, the significance of the invention also lies in that the reduced total weight of the screen body means the reduced bearing of the building accordingly, the safety is increased.
Description
Technical field
The present invention relates to the LED display field, relate in particular to the LED display of a kind of low energy consumption module, high-efficiency power, ultra-thinization, lightness, unitized structure.
Background technology
At present all LED display are almost all continued to use traditional design method, adopt the low-voltage, high-current powering mode, and energy consumption is big, efficient is low, screen body thermal value is very big, market day also become the energy consumption rich and influential family in demand satisfying.As shown in Figure 1, existing module adopts the low-voltage, high-current powering mode, and R, G, B lamp adopt divider resistance R power supply, and thermal value is big; And power supply adopts fixed power supply, low-voltage, high-current output: 5V/50A; Need in advance to mix up by the LED parameter value of buying, if the die change group then power parameter need readjust; Because of module and power supply thermal value are big, casing thickness usually must not be less than 120mm (low-light level screen/indoor application), and high brightness screen (outdoor) then must not be less than 150mm, and a plurality of fans heat radiations must be arranged, for outdoor large-size screen monitors (100m
2More than), consider factors such as quality weight, weak heat-dissipating and adopt expensive aluminium casing that the system that makes uses all kinds of wire rods thicker, the integrated cost height.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of LED display.
For solving the problems of the technologies described above, the objective of the invention is to be achieved through the following technical solutions.
A kind of LED display comprises: module part, power unit and structure division, described module partly adopts high pressure low current transmission mode, by division module the red, green, blue fluorescent tube is adopted the voltage adjustable power supply respectively.
Wherein, described power unit adopts the high pressure low-current power supply.
Wherein, described structure division LED casing adopts standard sections.
Wherein, described structure division LED casing adopts can manufacturing, and casing uses the universal architecture body.
Wherein, described structure division LED tank material is common cold-rolled steel sheet.
Beneficial effect of the present invention is as follows:
Module of the present invention adopts the transmission of high pressure low current, and divider resistance on the cancellation pcb board is powered respectively to R, G, B lamp, reduces loss, has reduced heat energy to greatest extent; Power supply adopts newly designed Switching Power Supply, has high-level efficiency, low in calories, low energy consumption, intelligent control; Structural design realizes weight reducing significantly at These characteristics, and its ultra-thinization, partly or entirely standardization, universalization, simplicity are achieved.Simultaneously simplified wrappage and design again, reduced transportation cost, the screen body general assembly (TW) that alleviates in addition for large-scale its meaning of outdoor screen has equaled to alleviate the load-bearing of building, has increased security.
Description of drawings
Fig. 1 is existing LED display module/power supply synoptic diagram;
Fig. 2 is LED display module of the present invention/power supply synoptic diagram.
Embodiment
For ease of the present invention is further understood, now reach specific embodiment in conjunction with the accompanying drawings and describe the present invention.
See also shown in Figure 2ly, LED display module of the present invention partly adopts high pressure (24V/10A; Tradition 5V/50A), low current transmission; By division module R (red), G (green), B (indigo plant) fluorescent tube are adopted the voltage adjustable power supply respectively, the cancellation divider resistance.Thereby the reduction useless power consumption reduces the module thermal source to greatest extent, and the power consumption of screen body reduces (more than 25%) significantly.LED display power unit of the present invention adopts up-to-date switch power technology; 24V/10A exports (high-level efficiency, low in calories), can realize intelligent control, can realize more effective power-supply system management with the interconnection of LED control system.
LED display structure division of the present invention is done following improvement:
(1): the casing moulding is because of the improvement of heat dispersion, adopts slimming or ultra-thinization and is achieved.
(2): body structure can be realized variation: can adopt (LED of different size get rid of front panel, after-frame reaches outdoors, and all the other outside framework section bars can be general, and just length dimension changes) such as standard sections, simplify assemble flow, realize assembling fast;
(3): can adopt traditional can manufacturing, because of overall weight alleviates, structure can realize simplicity, partly or entirely standardization, universalization.
(4): substitute expensive aluminium sheet, particularly outdoor large screen wall with common cold-rolled steel sheet, the past is for weight reduction and improve heat radiation and have to adopt aluminium, can use common iron case to replace now, has reduced cost significantly.
(5): structure can further be simplified, and reduces manufacturing procedure, reduces cost.
(6): except that particular surroundings, in most cases can reduce number of fans or cancellation fan.
(7): wrappage can be simplified, and reduce cost significantly, and trucking costs reduces; Various wire rods (external power cable, screen body power lead etc.) cross section reduces, and reduces cost significantly.
More than a kind of LED display provided by the present invention is described in detail, used specific case herein principle of the present invention and embodiment set forth, the explanation of above embodiment just is used for help understanding core concept of the present invention; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
