We present new methods for efficient estimation of the radiance incoming from disk-shaped light sources. For that, we introduce three novel area-preserving mappings for the projected solid angle of the disk. Our methods significantly improve over previous work, and have been implemented in a mainstream production-oriented render engine..Presentamos nuevos métodos para la estimación eficiente de la radiancia incidente proveniente de fuentes de luz con forma de disco. Por ello, introducimos tres nuevos mapeos conformes por área de la proyección en ángulo sólido del disco. Nuestros métodos mejoran significativamente el trabajo preexistente, y han sido implementado en un motor de render convencional orientado a producción
