Abstract
A heatsink for an optical module for a motor vehicle (V), wherein the heatsink includes a bent plate, the plate includes a central part adapted to receive at least one light source of the optical module and including two edges common with two lateral parts, the two common edges forming bending axes of the plate; and the two lateral parts each forming an angle (β) with the central parts.
Claims19
A heatsink for an optical module for a motor vehicle (V), wherein the heatsink comprises a bent plate, said bent plate including:
- a central part adapted to receive at least one light source of the optical module and including two edges common with two lateral parts, said two common edges forming bending axes of said bent plate, each of said two lateral parts including a pair of substantially parallel edges;
- and
- in an unbent state of the plate, said pair of substantially parallel edges of said two lateral parts each forming an angle with said respective common edge of said central part at which said respective lateral part is connected to said central part,
- wherein said angle is an acute angle.
A method of manufacturing a heatsink for an optical module for a motor vehicle, wherein said method of manufacture includes:
- cutting a sheet of a thermally conductive material to form a plate;
- bending said plate so as to form a central part and two lateral parts each forming an angle with said central part, said central part being adapted to receive at least one light source of said optical module.
An optical module for a motor vehicle, wherein the optical module comprises:
- a plate adapted to define a heatsink, said plate comprising;
- a central part adapted to receive at least one light source of the optical module and including two edges common with two lateral parts, the two common edges forming bending axes of said plate, each of said two lateral parts including a pair of substantially parallel edges;
- and
- in an unbent state of the plate, said pair of substantially parallel edges of said two lateral parts each forming an angle with said respective common edge of said central part at which said respective lateral part is connected to said central part;
- at least one optical surface adapted to be fixed to said heatsink and to cooperate with at least one light source;
- and
- said at least one light source adapted to be disposed on said heatsink,
- wherein said angle is an acute angle.
A lighting device for a motor vehicle, comprising;
- a housing;
- at least one optical module comprising a heatsink disposed on said housing, said heatsink comprising:
- a central part adapted to receive at least one light source of the optical module and including two edges common with two lateral parts, the two common edges forming bending axes of said plate;
- and
- said two lateral parts each forming an angle with said central part;
- at least one optical surface adapted to be fixed to said heatsink and to cooperate with at least one light source;
- and
- said at least one light source adapted to be disposed on said heatsink,
- wherein each of said two lateral parts is substantially shaped as a right trapezoid.
