Abstract
A light bar is described that is of a modular construction based on one or more large circuit boards that are populated with light beam assemblies and then fastened to an interior space of the light bar housing. Keys that automatically align the light beam assemblies on each of the boards precisely control placement of the assemblies on the board. In turn, each of the boards is keyed to the interior of the light bar housing so that when the board is fastened to the housing the light beam assemblies are automatically registered into alignment with the lenses in the housing so that the beams from the assemblies are properly oriented. The light bar is inexpensive to fabricate and can be assembled quickly and reliably, yet it provides for a high degree of customization, which is a requirement in the emergency vehicle lighting industry.
