Tunable impact feature in automotive lamps
An apparatus and a method for an automotive lamp are provided. The apparatus includes a housing made of plastic having an impact groove formed on a surface of the housing, wherein the impact groove is designed as a function of a depth, a width, a desired force, a cross section, and a profile to cause a designed rupture upon application of an applied force.
1. An apparatus for an automotive lamp comprising:
a housing made of plastic having an impact groove formed on a surface of the housing by a slide face insert attached to a cast of the housing formed by a one-shot molding process, wherein the impact groove is designed as a function of a depth, a width, a desired force, a cross section, and a profile to cause a designed rupture upon application of an applied force, wherein the impact groove includes a dimple at a corner of the profile of the impact groove.
2. The apparatus according to claim 1 , wherein the depth of the impact groove is a function of a desired force, which is a force at which a rupture should occur, and the cross section of the impact groove.
3. The apparatus according to claim 2 , wherein the cross section of the impact groove is a V-shape.
4. The apparatus according to claim 1 , wherein a width of the impact groove is a function of the desired force, which is a force at which a rupture should occur, required to cause a rupture and the cross section of the impact groove.
5. The apparatus according to claim 1 , wherein the impact groove includes one or more ribs disposed inside the impact groove.
6. An automotive lamp comprising:
a lamp;
a housing made of plastic having an impact groove formed on a top or a bottom surface of the housing by a slide face insert attached to a cast of the housing and a one-shot molding process, wherein the impact groove is designed to cause a rupture upon an external force and wherein the impact groove includes a dimple at a corner of a profile of the impact groove.
7. The automotive lamp according to claim 6 , wherein a depth of the impact groove is a function of a desired force, which is a force at which a rupture should occur, and the impact groove cross section.
8. The automotive lamp according to claim 7 , wherein the cross section of the impact groove is at least one of V-shape, cup-shape and rectangular shape.
9. The automotive lamp according to claim 6 , wherein a width of the impact groove is a function of the desired force and the impact groove cross section.
10. The automotive lamp according to claim 6 , wherein the impact groove includes at least one rib disposed inside the impact groove.
11. The apparatus according to claim 2 , wherein the cross section of the impact groove is a cup-shape.
12. The apparatus according to claim 2 , wherein the cross section of the impact groove has a varying depth and width along a length of the impact groove.
