Fig. 3 is the schematic diagram of embodiment 4 in the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of LED display 101, and LED display 101 comprises two or more pieces mounting bar, one or more power circuit, one or more signal line and some LED luminescence units; For example, comprise mounting bar 102a, mounting bar 102b two mounting bars, a positive source circuit, power cathode circuit, a bars circuit and some LED luminescence units 104.
Each mounting bar can be parallel to each other or vertically arrange, and at infall, interfixes.
Also can be one-body molded, on this basis, some reinforcements are set.
Each mounting bar is for each LED luminescence unit 104 is installed, thus composition the present embodiment LED display 101; And, each mounting bar can be fixed on and install on medium 105, as, medium 105 is installed and can, for fixed frame being installed, crossbeam, construction wall, installation plate etc. being installed, by each mounting bar installation is fixing, thereby be formed the firm LED display of an installation.By each mounting bar is installed, can guarantee that described LED display is disposed in the buildings of various shapes, easy for installation flexible.
Minor increment between each mounting bar is 5 centimetres, be apart from minimum, to be 5 centimetres between mounting bar 102a and mounting bar 102b, for example, arbitrary numerical value for 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 P25,0.5 centimetre to 2.5 centimetres, therefore, in the transmission screen of making, maximum spacing between adjacent PCB bar is 2.5 centimetres, be arranged on the exterior wall of building, easily shelter from the part visual field of people in building, make the transparency of LED display 101 can not meet the requirement of vision, and, because the spacing between the PCB bar is too small, radiating effect is also good not, is difficult to bear the huge temperature difference and hurricane.
Therefore, minor increment between each mounting bar is set to 5 centimetres, the space that between mounting bar, at least has 5 centimetres=25 square centimeters of 5 cm x, can, when enough meeting people's vision needs, reduce the energy consumption of LED display 101, and, spacing between mounting bar is larger, and the dot spacing be arranged between the LED luminescence unit 104 on each mounting bar is also larger, therefore, good heat dissipation effect, can bear the larger temperature difference; And, the form of the sparse installation position that the employing permeability is strong, contributing to increases the steadiness that the LED luminescence unit is installed, and even can resist the high wind hurricane.It should be noted that, the distance between adjacent mounting bar, can be the distance between the mounting bar edge, can be also 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, it is corresponding one by one with LED luminescence unit 104 that each mounting bar arranges ,Ji installation position, at least one installation position, and each installation position is for installing its corresponding LED luminescence unit 104; And the minor increment between each installation position is 5 centimetres.
For example, described installation position can or be provided with a certain ad-hoc location of fixed cell for a groove or draw-in groove, for correspondence, installs and fixes each LED luminescence unit, and for example, fixed cell can be screw, rivet, latch, clamp, buckle etc.
For example, the spacing of each installation position can be selected from arbitrary numerical value of following numerical value set, and its unit is centimetre, described set of values is combined into 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, 511, 522, 533, 544, 555, 566, 577, 588, 599, 600, 601, 602, 603, 604, 605, 606, 666, 707, 777, 800, 888, 900, 999, 1200.

Described solar panel, can be fixed on each mounting bar surface by various fixed cells, can be fixed on horizontal mounting bar and go up, and also can be fixed on perpendicular mounting bar.Various fixed cells can be: the fixed cells such as gib screw, fixing rivet, Fixed latches, scolding tin; Perhaps, can also be one-body molded with each mounting bar, make both fixing more firm each other, be not easy separately when installing, moving and using, or be collided, shake and damage.
Described solar panel is connected with outside storage battery, in use, solar panel is positioned under sunshine, for converting solar energy into electrical energy, and by electrical power storage in described accumulator, described accumulator also is connected with each power lead, is used to described LED display that the voltage source is provided.
Embodiment 6
On above-mentioned each routine basis, described LED display also arranges one or more identify units, for identifying the performance parameter of described LED display.
Each performance parameter of described LED display, can be in each LED luminescence unit, the brightness of each LED light emitting diode, wavelength, chromaticity coordinates etc., can also be color, encapsulation, the size of each LED light emitting diode, the spacing of each LED luminescence unit, and shape of each LED display, size etc.
In described LED display in each LED luminescence unit, when same color LED light emitting diode adopts same minute gear selecting or adjacent minute gear selecting, the brightness of same color LED light emitting diode, encapsulation, big or small identical, and consistent wavelength, therefore each LED light emitting diode of same color in a LED module, can see a LED light emitting diode as and be identified, and has accurate performance parameter numerical value, therefore, sign content is simple, convenient.
Each identify unit can adopt the mode that embeds or paste to arrange, can be arranged on arbitrary side of described LED display, identify unit is arranged on side, can make identify unit not take each LED light emitting diode, and the installation site of other electronic devices and components, and, do not affect display surface specious of described LED display yet.
And being embedded, identify unit is arranged on described LED display, can make identify unit depositing, use, be not easy to come off in the situation such as transportation, make the described panel through long storage time, use or transportation, still can clearly recognize each performance parameter of described LED display.
And for example, identify unit can be a paper labels or plastic label; The use paper labels can make to wait in use very convenient, for example, can directly paper labels be sticked on the side or side of described LED display, and identification means is simple, and convenient.And use plastic label can make label more durable, be not easy infringement.
In addition, identify unit can also be the bar code of each performance parameter of mark, like this, because identify unit has the bar code that each performance parameter according to described LED display designs, can show each specific performance parameter of described LED display by scanning; Adopt bar code, by data are inputted to computer, adopt the electronic tool management simultaneously, make management standardization more, make when finding, using each panel of each performance parameter convenient, quick.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
