The noun luminary (plural luminaries) can mean any source of light. It is also used to mean small makeshift lamps (luminaria) made from candles. In Spanish culture these are also called farolitos.
Idiomatically, luminaries are celebrities (eminent or famous people), so called originally because they inspire or "light the way" for others.
