"Luminous" in this context means "bright" - how much light (or how much energy in general) does the star emit. Note that stars look dim to us only because they are far away - some of them are actually several times brighter than our Sun, in absolute terms. That is, if you would see several stars, and our Sun, at a same standard distance, some stars would be dimmer, but others would be brighter, than our Sun.
