Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Embodiment 1

As shown in Figure 1, present embodiment provides a kind of LED display 101, and LED display 101 comprises two or many mounting bars, one or more power circuit, one or more signal line and plurality of LED light-emitting; For example, comprise mounting bar 102a, mounting bar 102b two mounting bars, a positive source circuit, power cathode circuit, a bars circuit and a plurality of LED light-emitting 104.

Each mounting bar can be parallel to each other or vertically be provided with, and interfixes at infall.

Also can be one-body molded, on this basis, plurality of strengthening ribs is set.

Each mounting bar is used to install each LED luminescence unit 104, thereby forms present embodiment LED display 101; And, each mounting bar can be fixed on and install on the medium 105, as, medium 105 is installed can by each mounting bar is installed and fixed, firm LED display be installed for installing and fixing framework, crossbeam, construction wall, installation plate or the like being installed thereby form one.By each mounting bar is installed, can guarantee that described LED display disposes in the buildings of different shape, easy for installation flexibly.

Minor increment between each mounting bar is 5 centimetres, be to be 5 centimetres apart from minimum between mounting bar 102a and the mounting bar 102b, for example, be arbitrary numerical value of following numerical value set, its unit is centimetre: 5,8,9,10,12,15,18,20,23,24,25,30,33,36,40,43,45,49,55,60,64,70,72,75,80,81,82,90,99,111,125,138,149,167,186,200,225,256,268,292,303,337,339,353,369,382,406,433,442,451,460,499,500,600,800,900,999,1200.

Because the dot spacing between the common LED display screen generally all is set to P5 to P25, promptly 0.5 centimetre to 2.5 centimetres, therefore, in the saturating abortive haul screen of making, maximum spacing between the adjacent PCB bar is 2.5 centimetres, be installed in the exterior wall of building, shelter from the part visual field of people in the building easily, make the transparency of LED display 101 can not satisfy the requirement of vision, and, because the spacing between the PCB bar is too small, radiating effect is also good inadequately, is difficult to bear the huge temperature difference and hurricane.

Therefore, minor increment between each mounting bar is set to 5 centimetres, the energy consumption of LED display 101 can be reduced in the space that then has 5 centimetres=25 square centimeters of 5 cm x between the mounting bar at least when enough satisfying people's vision needs, and, spacing between the mounting bar is big more, and the dot spacing that then is arranged between the LED luminescence unit 104 on each mounting bar is also big more, therefore, good heat dissipation effect can be born the bigger temperature difference; And, adopt the form of the strong sparse installation position of permeability, helping increases the steadiness that the LED luminescence unit is installed, and even can resist the high wind hurricane.Need to prove that the distance between the adjacent mounting bar can be the distance between the mounting bar edge, also can be the distance between the mounting bar center; The mounting bar center, i.e. the mounting bar of a rectangle or similar rectangle, at the center line of this rectangle, or any point on the class symmedian of similar rectangle; Two center lines of adjacent two mounting bars, parallel or approximate parallel.

Corresponding to each LED luminescence unit 104, each mounting bar is provided with at least one installation position, and promptly the installation position is corresponding one by one with LED luminescence unit 104, and each installation position is used to install its corresponding LED luminescence unit 104; And the minor increment between each installation position is 5 centimetres.
