21. A back light apparatus, comprising:
- a generally “
L”
shaped laminate comprises a first leg and a second leg, a cross-section of the “
L”
shaped laminate lying on a plane normal to a longitudinal axis of the laminate having the generally “
L”
shape and including a metal sub-section, a dielectric sub-section and one or more electrically conductive sub-sections, each of the sections being generally “
L”
shaped, wherein the first leg and the second leg of the “
L”
shaped laminate are connected together via a plastically deformed section;
one or more LEDs;
wherein the LED is in conductive heat transfer communication with the first leg of the “
L”
shaped laminate; and
the “
L”
shaped laminate transfers heat from the first leg of the “
L”
shaped laminate and then therefrom to the second leg of the “
L”
shaped laminate, through the plastically deformed section.
