Led heat sink and method of manufacturing same

Abstract

A LED heat sink and a method of manufacturing same are disclosed. The LED heat sink includes a holding zone bordered by one or more anchor portion of a higher elevation. The anchor zone has an upper side formed a compact stamping zone. The compact stamping zone is stamped forcefully through a mold in a diagonal direction towards the holding zone such that the material of the anchor zone is squeezed above the holding zone to form a latch hook to latch and press a LED lamp onto the holding zone so that the LED lamp is tightly in contact with the heat sink. Thus a forced transfer effect can be achieved to rapidly reduce the temperature of the LED lamp.

1 . A LED heat sink, comprising:
 one or more holding zone on a upper side of the heat sink; and   one or more anchor portion which borders the holding zone at a higher elevation and includes a latch hook at one side adjacent to the holding zone.   
     
     
         2 . The LED heat sink of  claim 1 , wherein the latch hook faces the holding zone and forms downward latching and pressing. 
     
     
         3 . The LED heat sink of  claim 1 , wherein the anchor portion is a jutting block. 
     
     
         4 . The LED heat sink of  claim 1 , wherein the anchor portion is a jutting strut. 
     
     
         5 . A LED heat sink formed in an elongate body insertable into a heat transfer duct, comprising:
 one or more holding zone located on an upper side of the heat sink;   a bundle portion located in a middle section of the heat sink; and   a heat transfer strut located at a bottom end of the heat sink.   
     
     
         6 . The LED heat sink of  claim 5 , wherein the holding zone borders one or more anchor portion which is higher than the holding zone. 
     
     
         7 . The LED heat sink of  claim 6 , wherein the anchor portion includes a latch hook at one side adjacent to the holding portion. 
     
     
         8 . The LED heat sink of  claim 5 , wherein the bundle portion has a plurality of indent rings. 
     
     
         9 . The LED heat sink of  claim 5 , wherein the bundle portion and the heat transfer strut are inserted into the heat transfer duct. 
     
     
         10 . The LED heat sink of  claim 9 , wherein the heat transfer duct includes an opening which couples the bundle portion from an outer side and is sealed through a mold to form tight coupling and sealing between the heat transfer duct and the bundle portion. 
     
     
         11 . A method for manufacturing a LED heat sink comprising the steps of:
 providing a heat sink prototype which has a holding zone on a upper side bordered by one or more jutting anchor portion which has an upper end formed a compact stamping zone;   providing at least one LED lamp and dispensing a heat transfer medium on the holding zone, and mounting the LED lamp onto the holding zone at a desired location;   providing a mold corresponding to the compact stamping zone of the anchor portion; and   stamping the compact stamping zone on an upper side thereof with the mold in a diagonal direction towards the holding zone to squeeze the material of the anchor portion beneath the compact stamping zone to the periphery of the LED lamp to form a latch hook to produce a tight coupling between the LED lamp and the heat sink to generate forced heat transfer effect.
