Abstract
Disclosed is a system for thermally distributing hot air generated in a vehicle headlamp. A channel is defined between different chambers in the headlamp to allow for air circulation, thus reducing hot spots inside the housing around light sources which might compromise internal structures or devices.
Claims13
A vehicle lighting system for improving internal thermal distribution, the system comprising:
- at least an upper compartment and lower compartment, each of said upper and lower compartments including a forward-facing reflector, the reflector having a reflective front, a back surface, and a bulb;
- a housing having an interior surface;
- a channel extending from the upper compartment down into the lower compartment, an upper portion of the channel defined by and between the interior surface of the housing, and the back surface of the reflector in the upper compartment, and a lower portion of the channel defined by and between the interior surface of the housing, and a back surface of the reflector in the upper compartment;
- and
- the channel creating a passageway, the passageway enabling the circulation of air between the upper and lower compartments.
A method for redistributing heat in a vehicle lighting system, the lighting system having a plurality of vertically-oriented compartments in a housing, each of the compartments including a reflector, the method comprising:
- creating an air passageway between the plurality of compartments by defining a channel in a space behind an interior surface of the housing and a rear surface of each reflector, the channel extending between each of the vertically-oriented compartments, thus allowing for the circulation of air between all of the plurality of vertically-oriented compartments.
An air flow channel in a lighting assembly housing, comprising:
- an upper compartment housing a first bulb and reflector arrangement;
- a lower compartment housing a second bulb and reflector arrangement;
- each of the upper and lower compartments presenting interior housing surfaces;
- at least one channel fluidly coupling the upper compartment with the lower compartment, thereby enabling air flow between the upper and lower compartments the airflow occurring between the back of each reflector and the interior housing surfaces for preventing localized hot spots due to entrapment of hot air in one of the upper compartment or the lower compartment.
