Abstract
An LED display assembly, comprising a grid of electrical conductors; light emitting diodes in association with the grid and in electrical communication with the conductors that provide power for LED operation, the grid operable to receive heat from the diodes during diode operation, and the array configured for passing coolant fluid for transfer of heat to the fluid. LED packages adjustable relative to a mounting grid, are also provided.
Claims58
The method of providing an LED array assembly, that includes:
- a) providing a grid of electrical conductors, certain of which provide electrical power,
- b) providing light emitting diodes and locating the diodes in association with the grid and in electrical communication with said certain conductors that provide power, for LED operation,
