Fig. 4 is the assembling synoptic diagram of the LED display of the utility model preferred embodiment.
[embodiment]
See also Fig. 1 and Fig. 2, Fig. 1 is the installed surface structural representation of the utility model LED display heat sink, and Fig. 2 is the radiating surface synoptic diagram of the LED display heat sink of the utility model preferred embodiment.The LED display heat sink 1 of present embodiment roughly is tabular, and it simultaneously is and the fixing installed surface of LED casing 2, another side for the radiating surface (consulting Fig. 4) of pcb board 4 location and installation.
The installed surface of heat sink 1 comprises the lamp plate components and parts via hole 10 of being located at heat sink 1 middle part, wears heat sink 1 for the components and parts on the lamp plate when being used to lamp plate is installed.The installed surface of heat sink 1 also offers the reinforcement 11 of many strip projections, and described many reinforcements 11 be arranged in parallel, is used for preventing that heat sink 1 is in the installation process distortion that is squeezed; Heat sink 1 also comprises a plurality of module pilot holes 16 that are provided with along vertical reinforcement 11 directions of a plurality of casing fixed orifices 12 of reinforcement 11 bearing of trends setting and edge, wear casing fixed orifice 12 by double-screw bolt 13 and heat sink 1 can be fixedly connected on LED casing 2, wear module pilot hole 16 by reference column 17 and heat sink 1 can be fixedly connected on led module (figure does not show).In the present embodiment, casing fixed orifice 12 is four, and module pilot hole 16 is two.
In addition, heat sink 1 at its two ends along reinforcement 11 bearing of trends also symmetry offer a plurality of LED lamp plate fixed orifices 18, be used for heat sink 1 and LED lamp plate (figure does not show) are fixedlyed connected.LED lamp plate fixed orifice 18 is six in the present embodiment.
See also Fig. 2, the radiating surface middle part of the utility model LED display heat sink 1 is provided with a groove 19, is used for fixing thicker IC plate.
The utility model LED display heat sink 1 adopts aluminium section bar, its material thickness had so both increased area of dissipation less than common heat sink sheet material, had improved radiating effect, improve heat sink intensity again, helped improving the anti-extrusion deformation intensity of LED display heat sink 1.
The utility model provides a kind of LED display simultaneously.
See also Fig. 1 to Fig. 4, during the assembled LED display screen, with the installed surface of LED display heat sink 1 towards LED casing 2, the radiating surface of LED display heat sink 1 is towards pcb board 4, wear casing fixed orifice 12 by double-screw bolt 13, thereby heat sink 1 is fixedly connected on LED casing 2, again reference column 17 is worn module pilot hole 16, thereby heat sink 1 is fixedly connected on described led module; Simultaneously, wear LED lamp plate fixed orifice 18, thereby heat sink 1 is fixedlyed connected with described LED lamp plate by fixture such as double-screw bolt.Heat sink and LED casing 2, pcb board 4 and the LED lamp plate firm and reliable connection of assembling back LED display, and the heat sink extrusion is less.
