Apparatus for using heat pipes in controlling temperature of an LED light unit
A light emitting diode (LED) light unit is disclosed. For example, the LED light unit includes at least one support plate having one or more inner openings. At least one LED array may be coupled to an LED board. The LED light unit also includes at least one heat pipe coupled to the LED board, wherein said LED board is coupled to the at least one support plate.
1. A light emitting diode (LED) light unit comprising:
a plurality of support plates, wherein each one of said plurality of support plates has one or more inner openings and each one of said plurality of support plates is stacked vertically and coupled to a center column;
at least one LED array coupled to an LED board;
a heat collector coupled to said LED board; and
at least one heat pipe coupled to said heat collector such that said at least one heat pipe is directly beneath and parallel to said at least one LED array, wherein said at least one heat pipe is coupled to one of said plurality of support plates, wherein said at least one heat pipe of an uppermost one of said plurality of support plates is located through and adjacent to said one or more inner openings of said uppermost one of said plurality of support plates and wherein said at least one heat pipe of each one of said plurality of support plates below said uppermost one of said plurality of support plates is located adjacent to said at least one heat pipe of said uppermost one of said plurality of support plates in a line radially inward.
