Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of LED that this embodiment provides shows module as shown in Figures 1 and 2, comprising: face shield 1, bucker 2, PCB3 and module drain pan 4.Face shield 1 fits together common formation one accommodation space 100 with module drain pan 4, and PCB3 is positioned at accommodation space 100, is provided with some electron devices in PCB3, and bucker 2 covers at the outside surface of PCB3.
Please together consult Fig. 3 to Fig. 8, module drain pan 4 comprises plastic casing 41 and metal shell 42.Plastic casing 41 is combined as a whole by mode and the metal shell 42 of injection mo(u)lding.In the present embodiment, module drain pan 4 has 42, two metal shells 42 of two metal shells and is intervally arranged, and on plastic casing 41, forms two disposal areas of running through (not indicating in figure) along its thickness direction, and metal shell 42 is embedded in the disposal area of plastic casing 41.Heating electron device 31(on PCB3 is as drive IC etc.) be positioned at the corresponding region of metal shell 42, and be close to metal shell 42 and arrange, like this, the heat that heating electron device 31 produces can directly be dispersed in external environment condition by metal shell 42.
Above-mentioned module drain pan 4 is combined as a whole plastic casing 41 and metal shell 42 by the mode of injection mo(u)lding, adds man-hour, will play metal shell 42 and be put in advance in plastic mould, realizes the combination of plastic cement and metalwork by injection moulding plastic in mould.Member is at the complex structure of plastic cement part, can realize by the mode of injection moulding, and metal shell 42 is in playing thermolysis, also can strengthen intensity and the rigidity of plastic parts, such module drain pan 4 has lightweight, and intensity, rigidity are moderate, waterproof, good heat dispersion performance, cost of parts is low, advantage with short production cycle.
Particularly, metal shell 42 can be made up of the good metal material of heat conductivility (as aluminium or aluminium alloy etc.), and its quantity and the arrangement mode in plastic casing 41 can be selected according to the particular location of the electron device 31 that generates heat on PCB3 in LED display.Metal shell 42 comprises base 421 and some heat radiator 422.Heat radiator 422 is extended to the outside of module drain pan 4 by base 421, and parallel arrangement in horizontal direction.Certainly, the arrangement mode of heat radiator 422 is not limited to aforesaid way, as long as it can realize increasing heat radiation area, can be by heat Quick diffusing to extraneous, and such as also parallel arrangement etc. in vertical direction of heat radiator 422.
In the present embodiment, the internal face that plastic casing 41 envelopes metal shell 42 peripheries protrudes from the internal face of metal shell 42 peripheries; The periphery thinner thickness of metal shell 42, its peripheral position forms step surface 424 in outside wall surface indent, and through hole 423 is positioned on step surface 424, and plastic casing 41 envelopes step surface 424, and the outside wall surface at plastic casing 41 encapsulate positions is concordant with peripheral outer wall face.As other embodiment, plastic casing 41 also can be similar with the mode of above-mentioned outside wall surface with the combination of metal shell 42 periphery internal faces, it is metal shell 42 peripheral positions form indent step surface in internal face, plastic casing 41 envelopes step surface, and the internal face at plastic casing 41 encapsulate positions is concordant with periphery internal face.
Because plastic cement and metal are two kinds of different types of materials, in the process of injection mo(u)lding, Material shrinkage can cause internal stress, and the contraction missionary society that especially drain pan size increases latter two material strengthens.In the present embodiment, the position near metal shell 42 peripheries on plastic casing 41 is also provided with groove position 414, shrinks residual quantity for absorbing.Groove position 414 is recessed to form by the internal face of plastic casing 41, and its cross section is " U " shape, and certainly, the cross sectional shape of groove position 414 can also be " W " shape or waveform etc.
Above-mentioned LED shows that the module drain pan of module is easy to manufacture, and in possessing good waterproof, heat dispersion, also possesses certain intensity and rigidity, is especially applicable to the LED display that outdoor environment uses.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
