Abstract
A lighting device (100) can include multiple light sources (170) that emit light along a range of radiation paths (195). The lighting device (100) can also include a reflective component (130-1) disposed proximate to at least a portion of a first side interior surface in a first portion (195-2) of the range of radiation paths (195), where the light in the first portion (195-2) of the range of radiation paths (195) reflects off of the reflective component (130-1). The lighting device (100) can further include a housing (105) having an optical feature (120) adjacent to the reflective component (130-1), where the light in the first portion (195-2) of the range of radiation paths (195), after reflecting off of the reflective component (130-1), passes through the optical feature (120) into a first part (140-2) of an ambient environment (140). The reflective component (1301) can be adjacent to an opening through which a second portion (195-1) of the range of radiation paths (195) passes into a second part (140-1) of the ambient environment (140).
