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.

L'invention concerne une barre lumineuse qui est d'une conception modulaire fondée sur une ou plusieurs grandes cartes imprimées qui sont garnies d'ensembles de faisceaux lumineux puis sont fixées sur un espace intérieur du boîtier de barre lumineuse. Des clavettes qui alignent automatiquement les ensembles de faisceaux lumineux sur chacune des cartes commandent précisément le placement des ensembles sur la carte. À son tour, chacune des cartes est calée sur l'intérieur du boîtier de la barre lumineuse de telle sorte que, lorsque la carte est fixée sur le boîtier, les ensembles de faisceaux lumineux soient alignés automatiquement avec les lentilles dans le boîtier de manière telle que les faisceaux provenant des ensembles soient orientés convenablement. La barre lumineuse est bon marché à fabriquer et peut être assemblée rapidement et de manière fiable, de plus elle permet un degré élevé de personnalisation, ce qui représente une exigence dans l'industrie des éclairages des véhicules d'urgence.
