Abstract

A heat sink assembly for quickly coupling and uncoupling to an arc lamp package includes a front heat sink and a rear heat sink coupled by insulators. Both of the heat sinks and the insulators are longitudinally split. One insulator is provided with hinges and the other with a latching device so that the heat sink assembly can be opened and clamped closed easily. The interior of the heat sinks are profiled to conform to a known lamp package but with a slightly smaller diameter. The rear heat sink is preferably provided with a hole for the lamp package's locating pin and the front heat sink is provided with a light exit port. Rectangular and cylindrical embodiments of the invention are disclosed. In the rectangular embodiment, the cooling fins can be arranged either horizontally or vertically. A lever latching device and a knob latching device are also disclosed. When the latching device is unlocked, the heat sink assembly can be opened like a book and the lamp package installed in its profiled recesses. When the assembly is closed and the latching device is locked, the lamp package is clamped firmly between the split front and rear heat sinks so that each heat sink makes a good ele…
