An apparatus is provided for facilitating servicing of an electronics rack. The apparatus includes a light source, which includes a plurality of light-emitting diodes. The plurality of light-emitting diodes are secured to the electronics rack or a floor tile disposed adjacent to the electronics rack, and are configured to illuminate at least a lower portion of the electronics rack at either the air inlet or air outlet side of the rack. A power supply is also provided for selectively supplying power to the plurality of light-emitting diodes. In one implementation, the light source includes an elongate light bar, which is configured to mount to either the inlet door or outlet door of the electronics rack, and the plurality of light-emitting diodes are secured to an elongate housing structure which pivotally couples to a base plate for adjustment of a direction of illumination by the light-emitting diodes.

What is claimed is: 1. An electronics system comprising: an electronics rack, the electronics rack comprising: a rack frame; at least one electronics subsystem disposed within the electronics rack and supported by the rack frame; a door hingedly mounted along one edge to the rack frame of the elect
What is claimed is: 1. An electronics system comprising: an electronics rack, the electronics rack comprising: a rack frame; at least one electronics subsystem disposed within the electronics rack and supported by the rack frame; a door hingedly mounted along one edge to the rack frame of the electronics rack at one side thereof; and an apparatus for facilitating servicing of the electronics rack, the apparatus comprising a light source mounted to an inside of the door of the electronics rack, the light source comprising: a plurality of light-emitting diodes, the plurality of light-emitting diodes being sized to illuminate at least a portion of the electronics rack at the one side thereof to facilitate servicing of at least the portion of the one side of the electronics rack, wherein the light-emitting diodes comprise multiple diodes of different beam patterns of light emitting therefrom, and wherein the diodes of different beam patterns of light are arrayed in an alternating arrangement of different beam patterns of light; an elongate light bar, the elongate light bar comprising a base plate and an elongate, light-emitting diode support structure pivotally connected to the base plate, wherein the plurality of light-emitting diodes are disposed along the elongate, light-emitting diode support structure, and the base plate is mounted to the inside of the door, and wherein the elongate, light-emitting diode support structure pivots relative to the base plate to allow pivoting of the light-emitting diode support structure towards the one side of the electronics rack with pivoting of the door away therefrom, to facilitate illumination of the portion of the electronics rack with opening of the door in any of a plurality of angles relative to the electronics rack; a power supply for supplying power to the plurality of light-emitting diodes; and wherein the door is hingedly mounted along a proximal edge to the rack frame and wherein the elongate light bar is mounted to the inside of the door adjacent to the proximal edge thereof to facilitate illumination of the one side of the electronics rack with pivoting open of the door in any of the plurality of angles relative to the electronics rack. 2. The electronics system of claim 1, wherein the electronics rack comprises an air inlet door and an air outlet door, the air inlet door being hingedly mounted along a proximal edge to the rack frame at an air inlet side of the electronics rack, and the air outlet door being hingedly mounted along a proximal edge to the rack frame at and air outlet side of the electronics rack, the door being one of the air inlet door or the air outlet door. 3. The electronics system of claim 2, wherein the elongate light bar is mounted vertically to the inside of the door along the proximal edge thereof. 4. The electronics system of claim 3, wherein the elongate light bar is mounted to the door via a temporary attachment mechanism coupled to the elongate light bar. 5. The electronics system of claim 2, wherein the base plate is mounted to the inside of the door within a recessed region of the door adjacent to the proximal edge thereof, and wherein the light source does not project past an edge of the door contacting the electronics frame when the door is in closed position. 6. The electronics system of claim 1, wherein the light-emitting diode support structure comprises an at least partially angled surface from which the plurality of light-emitting diodes extend in multiple columns, the plurality of light-emitting diodes comprising a first plurality of diodes of a first beam pattern and a second plurality of diodes of a second beam pattern, and wherein diodes of the first beam pattern and diodes of the second beam pattern alternate in each column of the array. 7. The electronics system of claim 6, wherein the diodes of the first beam pattern emit a 2× wider beam pattern than diodes of the second beam pattern. 8. The electronics system of claim 7, wherein the at least partially angled surface comprises three surface sections, each extending at an angle to at least one other surface section of the three surface sections, and wherein the multiple columns comprise three columns, each column being associated with a different surface section of the three surface sections of the light-emitting diode support structure.
