Abstract:
1. An LED light assembly comprising: a first support parallel with a first plane, said support including a heat sink and a PC board to which are mounted a first plurality of LEDs, said first plurality of LEDs arranged along a first linear focal axis parallel with said first plane and included in a second plane perpendicular to said first plane, each of said first plurality of LEDs emitting light in a hemispherical pattern directed away from said first plane, each of said LEDs having an optical axis in said second plane and emitting narrow angle light at angles less than a first angle with respect to said second plane and wide angle light at angles greater than said first angle with respect to said second plane; an optical element arranged to collect light from said first plurality of LEDs, said optical element comprising first, second and third light entry surfaces and first, second and third light emission surfaces, said first and second light entry surfaces and first and second light emission surfaces separated by said second plane and said third light entry surface and said third light emission surface are bisected by said second plane, said first and second light entry surfaces configured to cooperate with said first and second light emission surfaces, respectively, to re-direct wide angle light emitted from said first plurality of LEDs into a trajectory substantially parallel with said first plane, and said third light entry surface cooperates with said third light emission surface to re-direct narrow angle light emitted from said first plurality if LEDs into a trajectory substantially parallel with said second plane; and a reflector having first and second reflecting surfaces arranged to reflect wide angle light emitted from said first and second light emission surfaces, respectively, into a trajectory substantially parallel with said second plane, said first and second reflecting surfaces separated by said second plane and spaced apart from said first and second light emission surfaces, wherein said first linear focal axis extends between the optical axes of LEDs defining longitudinal ends of said first plurality of LEDs, said first, second and third light entry surfaces and said first, second and third light emission surfaces are defined by a cross sectional shape of said optical element projected along said first linear focal axis.
