A light system is provided. The light system includes: (a) a lamp head assembly, the lamp head assembly including (i) driver circuits, and (ii) a cooling system; and (b) a replaceable assembly connected to the lamp head assembly, the replaceable assembly including (i) a plurality of light producing elements, (ii) a cooling structure for receiving a cooling fluid from the cooling system, the plurality of light producing elements being supported by the cooling structure, and (iii) a reflector for receiving light from the plurality of light producing elements. The replaceable assembly is separable, as a single assembly, from the lamp head assembly.

Light systems including field replaceable assembly, and methods of assembling and operating the same

A lamp head assembly is provided. The lamp head assembly includes a thermally conductive block, an inlet cooling fluid pipe coupled to the thermally conductive block such that a cooling fluid is configured to pass from the inlet cooling fluid pipe to the thermally conductive block, and a metal heat exchanger secured to the thermally conductive block. The metal heat exchanger defines a plurality of internal channels to distribute cooling fluid provided by the inlet cooling fluid pipe. The metal heat exchanger is secured to the thermally conductive block such that the cooling fluid is configured to pass from the thermally conductive block to the plurality of internal channels defined by the metal heat exchanger. The lamp head assembly also includes a plurality of light producing elements secured to the metal heat exchanger.
