Abstract
Official abstract text for this publication.
An optical module comprising a heat sink having one or more heat dissipating surfaces, a fan for sending air over the one or more heat dissipating surfaces, and a light source held by the heat sink. The main feature of an optical module according to the invention is that the fan is mounted on the heat sink by clipping.
First claim
Opening claim text (preview).
What is claimed is: 1 . A optical module comprising a heat sink having one or more heat dissipating surfaces, a fan for sending air over said one or more heat dissipating surfaces, and a light source held by said heat sink, wherein said fan is mounted on said heat sink by clipping. 2 . The optical module according to claim 1 , wherein said heat sink comprises a housing having one or more edges and at least two deformable clipping tabs projecting from at least one of said one or more edges, and in that said fan is placed on said heat sink between said at least two deformable clipping tabs. 3 . The optical module according to claim 2 , wherein said housing has two clipping tabs projecting from two opposite edges facing one another. 4 . The optical module according to claim 3 , wherein each of said two clipping tabs has three segments and two bends, and in that a distance between said two clipping tabs is less than the dimensions of said fan so that said fan is mounted on said heat sink by virtue of said two clipping tabs moving apart. 5 . The optical module according to claim 3 , wherein said two clipping tabs are inclined with respect to one another so as to facilitate insertion of said fan. 6 . The optical module according to claim 2 , wherein each of said one or more edges has at a top at least one fan positioning member projecting from said housing in the same direction as said two clipping tabs. 7 . The optical module according to claim 1 , wherein said heat sink has a plurality of dissipating surfaces formed by parallel fins. 8 . The optical module according to claim 7 , wherein said parallel fins are separated from one another. 9 . The optical module according to claim 7 , wherein said parallel fins are continuous with one another to form a single piece. 10 . The optical module according to claim 7 , wherein said parallel fins are made of aluminum. 11 . The optical module according to claim 1 , wherein said light source comprises at least one light emitting diode. 12 . The optical module according to claim 1 , wherein said fan is mounted on said heat sink by sliding said fan along said heat sink and then locking by clipping. 13 . The optical module according to claim 12 , wherein said sliding is effected through interaction between two grooves and two rails, said two grooves belonging to one of the two elements consisting of said heat sink and said fan, and said two rails belonging to the other element. 14 . A heat sink for producing an optical module according to claim 1 . 15 . A vehicle headlamp comprising at least one optical module according to claim 1 . 16 . The optical module according to claim 4 , wherein said two clipping tabs are inclined with respect to one another so as to facilitate insertion of said fan. 17 . The optical module according to claim 3 , wherein each of said one or more edges has at a top at least one fan positioning member projecting from said housing in the same direction as said two clipping tabs. 18 . The optical module according to claim 2 , wherein said heat sink has a plurality of dissipating surfaces formed by parallel fins. 19 . A vehicle headlamp comprising at least one optical module according to claim 2 . 20 . A vehicle headlamp comprising at least one optical module according to claim 3 .
