Abstract

Vehicle light assembly housings, methods for making such housings and methods of using such housings, and motor vehicles having light assemblies employing such housings are disclosed. A protective lamp housing for an automotive lamp assembly is disclosed. The light housing includes a housing body attached to a vehicle structure of a motor vehicle. The housing body has an inner chamber in which the light source is stored. The housing body has an open end attached to the light-transmitting lens to fluidly isolate the inner chamber. A heat sink having a plurality of convection fins protruding from the thermally conductive body is integrally formed with the housing body. When engaged in this manner, the body extends into the inner chamber and the fins extend out of the housing body. The body of the heat sink and the fins are collectively configured to dissipate heat from the inner chamber.

Description

technical field [0001] The present invention generally relates to light assemblies for motor vehicles. More specifically, aspects of the invention relate to vehicle headlights and taillights having heat sinks for dissipating heat from the lamp housings. Background technique [0002] Current motor vehicle products, such as contemporary automobiles, were initially equipped with lighting systems to provide interior and exterior illumination for the vehicle operator and passengers. Such lighting systems include a variety of light assemblies that are mounted or otherwise integrated into the front, side, and rear of the vehicle. The purpose of these light assemblies is, for example, to provide exterior lighting to the driver, to operate the vehicle in low light conditions, such as driving at night, and to increase the visibility of the vehicle, such as in bad weather. Such lighting systems may also display information regarding the vehicle's presence, location, size, direction o...
