Abstract
An apparatus, system, and method for cooling a lamp assembly is described herein. The apparatus includes an air channel and an axial slot. A flow of air is injected into the air channel of a lamp housing, wherein the lamp housing comprises at least a bulb. The axial slot is located in a reflector housing and has dimensions that enable a constant flow of air through the slot and across the bulb when a predetermined air flow is input to the air channel.
Claims15
An apparatus for cooling a lamp assembly, comprising:
- an air channel to direct a flow of air into a lamp housing, wherein the lamp housing comprises at least a bulb;
- and
- an axial slot, wherein the axial slot is located in a reflector housing and has dimensions that enable a constant flow of air through the slot and across the bulb when a predetermined air flow is input to the air channel.
A method for cooling a lamp assembly, comprising:
- injecting a flow of air into an air channel of a lamp housing, wherein the lamp housing comprises at least a bulb;
- directing the flow of air from the air channel through a single axial slot that has dimensions the enable a constant flow of air through the slot and across the bulb when a predetermined air flow is input to the air channel;
- and
- guiding the flow of air away from the bulb.
A system for cooling a lamp assembly, comprising:
- a lamp tube to generate heat;
- a reflector to direct light produced by the lamp tube, wherein the reflector includes a least one axial slot;
- an air channel that directs an air flow across the lamp tube via the axial slot, wherein the axial slot has dimensions that enable a constant flow of air through the axial slot and across the bulb when a predetermined air flow is input to the air channel;
- and
- a second air channel to guide hot air away from the lamp tube.
