Abstract
A system and method of cooling a bulb of a type that requires cooling in one part, but not in others. A deflector assembly is coupled through a reflector, to the bulb, to cool only one part.
Claims16
A lighting fixture, comprising:
- a lighting reflector;
- a lighting socket located within said lighting reflector;
- a cooling air aperture, extending into an inside of said lighting reflector, and configured to cool only a specified area within said lighting reflector, wherein said cooling air aperture includes a device with inner surfaces defining a channel for air to first flow in a first direction, and to second flow in a second direction which is in a generally different direction than said first direction.
A lighting fixture, comprising:
- a lighting reflector;
- a lighting socket located within said lighting reflector;
- a cooling air aperture, extending into an inside of said lighting reflector, and configured to cool only a specified area within said lighting reflector;
- a fan, forming a stream of cooling air, and directing said cooling air to said cooling air aperture.

A lighting fixture, comprising:
- an optical reflector, having a first reflecting part, and a second non reflecting part;
- a bulb socket, formed in said second non reflecting part;
- and
- a cooling air chimney portion, extending from a first point outside said optical reflector, to a second point inside said optical reflector, and forming a channel for cooling air inside said optical reflector that is directed along a confined path, inside said chimney portion, wherein said chimney portion includes an inner cavity extending generally along a first direction, and an end portion which deflects cooling air from said first direction to a second direction generally toward said bulb, away from said first direction.

A lighting fixture, comprising:
- an optical reflector, having a first reflecting part, and a second non reflecting part;
- a bulb socket, formed in said second non reflecting part;
- a cooling air chimney portion, extending from a first point outside said optical reflector, to a second point inside said optical reflector, and forming a channel for cooling air inside said optical reflector that is directed along a confined path, inside said chimney portion;
- and
- a bulb, connected to said socket, said bulb having a first portion with a first temperature requirement, and a second portion with a second temperature requirement, wherein said second portion has a temperature requirement which avoids the need for cooling, and said first portion requires cooling.
2 more elements
A lighting fixture, comprising:
- an optical reflector;
- a fixture for a bulb which produces light which is to be reflected by said optical reflector;
- and
- a cooling air portion, located in a location inside said optical reflector where it will not interfere with light being produced by said bulb and coupled to said optical reflector and which directs air in a direction that is toward a first area and away from another area inside said optical reflector.
