Detailed description of the invention
As shown in Figure 1-Figure 3, Fig. 1 is the structural representation of an embodiment of the present invention with the lampshade 10 of cooling piece; Fig. 2 is the exploded perspective view of the lampshade 10 with cooling piece shown in Fig. 1; Fig. 3 is the structural representation of the multiple reflectors 130 shown in Fig. 2.
Should comprise with the lampshade 10 of cooling piece: the second panel 120 that the first panel 110 and the first panel 110 are oppositely arranged and the multiple reflectors 130 be connected between the first panel 110 and the second panel 120.The length that first panel 110 edge is also connected with multi-disc first fin 140, first fin 140 is greater than the distance between the first panel 110 and the second panel 120.First fin 140 is also connected with the second panel 120, is all connected with the first heat insulation layer between the first panel 110 and the first fin 140 and between the first fin 140 and the second panel 120, and the making material of the first heat insulation layer can be plastics or rubber.First panel 110 and the second panel 120 are circle and equal and opposite in direction.Multi-disc second fin 122 is connected with between first panel 110 and the second panel 120.First fin 140 and the second fin 122 all arrange along the edge circle spacing of the first panel 110.
Reflector 130 is connected one end with the first panel 110 and is provided with the first rim of a cup 131, and reflector 130 is connected one end with the second panel 120 and is provided with the second rim of a cup 132.First panel 110 be provided with the first rim of a cup 131 one to one resigning hole 111, second panel 120 be provided with and the second rim of a cup 132 light hole 121 one to one.First panel 110 is arranged with lens in light hole 121.
Semiconductor chilling plate 150 is provided with between first panel 110 and the second panel 120.The thickness of semiconductor chilling plate 150 is less than the distance between the first panel 110 and the second panel 120.Semiconductor chilling plate 150 is instruments of a heat trnasfer.When the thermocouple centering that one block of N-type semiconductor material and one block of P-type semiconductor material are coupled to have electric current by time, will produce transfer of heat between two ends, heat will transfer to the other end from one end, thus produces the temperature difference and form cold and hot end.After switching on power, produce electron-hole pair near upper contact, interior energy reduces, and temperature reduces, and outwardly absorbs heat, is called cold junction.The other end is because of electron-hole pair compound, and interior energy increases, and temperature raises, and to environment heat release, is called hot junction.The cold junction of semiconductor chilling plate 150 is connected with the first panel 110 center, and semiconductor chilling plate 150 hot junction is near the second panel 120.Semiconductor chilling plate 150 hot junction end face is connected with heat pipe 160.Heat pipe 160 is connected one end between the first panel 110 and the second panel 120 with semiconductor chilling plate 150, and in swirl shape, swirl shape is more conducive to the heat absorbing semiconductor chilling plate 150 hot junction.Heat pipe 160 passes across the edge arriving the first panel 110 between spaced reflector 130 from semiconductor chilling plate 150 hot junction.Heat pipe 160 and the second panel 120 and be connected with the first heat insulation layer between heat pipe 160 and reflector 130, the making material of the first heat insulation layer is plastics or rubber.
Heat pipe 160 away from semiconductor chilling plate 150 one end in the shape of a spiral.Every sheet first fin 140 is equipped with multiple connecting hole 141, and the radius of connecting hole 141 is equal with the radius of heat pipe 160.Heat pipe 160 passes connecting hole 141 and is connected with the first fin 140, and the joint face of heat pipe 160 and the first fin 140 also scribbles heat conductive silica gel to reduce thermal resistance.
The above-mentioned lampshade 10 with cooling piece, is designed to the structure of dispelling the heat superposed by the first panel 110 and the second panel 120 by lampshade.When lampshade is used for being combined with LED, the first panel 110 can be arranged on surface closely with on the substrate of LED lamp bead.Resigning hole 111 and the first rim of a cup 131 can hold LED lamp bead by one_to_one corresponding.Such first panel 110 can press close to substrate more, can the heat of effective absorptive substrate.Because the first panel 110 is connected with the cold junction of semiconductor chilling plate 150, therefore semiconductor chilling plate 150 can carry out active heat removal to the first panel 110.The hot junction of semiconductor chilling plate 150 is connected with heat pipe 160, and therefore the heat in semiconductor chilling plate 150 hot junction can pass in the first fin 140 by heat pipe 160.Heat can be shed fast by multi-disc first fin 140, thus improve radiating efficiency.
Set out in unthreaded hole 121 by multiple lens card, be different from tradition larger lens and be enclosed in lamp body by multiple reflector 130, multiple lens card is located in light hole 121 can abdicate space to arrange louvre to the second panel 120.Multi-disc second fin 122 be arranged between two panels can provide larger area of dissipation to help lampshade heat radiation.Be connected with the heat that heat insulation layer can reduce semiconductor chilling plate 150 hot junction between first panel 110 and the first fin 140 to transfer back in the first panel 110.
The above embodiment only have expressed preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
