MICRO-CHANNEL-COOLED HIGH HEAT LOAD LIGHT EMITTING DEVICE |
摘要 |
Micro-channel-cooled UV curing systems and components thereof are provided. According to one embodiment, a lamp head module includes a high aspect ratio, high fill factor array of light emitting devices and a submount. The array includes multiple groups of electrically seriesed light emitting devices that are connected in electrical parallel. The submount is of monolithic construction and includes multiple L-shaped patterned circuit material layers. Each of the L-shaped patterned circuit material layers includes an arm portion and a stem portion. The arm portion functions as a light emitting device bond pad and the stem portion functions as a wire bond pad and a circuit trace. Each light emitting device of a group is affixed to a corresponding arm portion of the submount. The stem portions are located external to the array, run parallel to the length of the array and perform a primary current carrying function for current flow between adjacent light emitting devices of the group. |

1. A lamp head module comprising:
an array of light emitting devices, the array having a high aspect ratio in which a length of the array is greater than a width of the array; and a pair of optical macro-reflectors to direct photons emitted by the array, the pair of optical macro-reflectors configured to produce a beam pattern on a surface of a workpiece, wherein the pair of optical macro-reflectors form an entrance aperture and an exit aperture, wherein the entrance aperture is positioned proximate to a light emitting surface of the array, wherein the exit aperture is located at a distal end of the pair of optical macro-reflectors, and wherein the entrance aperture has an area that is larger than an area of the light emitting surface. |
