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, wherein a flow of air is injected into the air channel of a lamp housing having an open end and a closed end opposite the open end, wherein the lamp housing comprises at least a bulb;
- and
- an axial slot, wherein the axial slot is sized based on the air flow to enable a constant flow of air through the axial slot and across the bulb;
- and
- wherein air is input into the air channel through the open end of the lamp housing and forced through the axial slot, across the bulb, and back out through the open end of the housing.
A method for cooling a lamp assembly, comprising:
- injecting a flow of air into an air channel through an open end of a lamp housing, wherein the lamp housing comprises at least a bulb;
- directing the flow of air against a closed end of the lamp housing opposite the open end, through an axial slot, across the bulb, and back out through the open end of the lamp housing, the axial slot sized, based on the air flow, to enable a constant flow of air through the slot and across the bulb;
- and
- guiding the flow of air away from the bulb.
A system for cooling a lamp assembly, comprising:
- a lamp tube that generates 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 from an open end of the assembly, against a closed end of the assembly opposite the open end, across the lamp tube via the axial slot, and back out through the open end of the assembly, wherein the size of the axial slot is based on the air flow;
- and
- a second air channel to guide hot air away from the lamp tube.
