Figure 12From: Packaging efficiency in phosphor-converted white LEDs and its impact to the limit of luminous efficacy A comparison of the calculated limit of luminous efficacy of the pcW-LEDs in different phosphor recipes. The end of yellow bar is for LER, the end of blue bar is for limit of luminous efficacy of a pcW-LEDs, and the end of green is for the practical limit of the luminous efficacy.Back to article page
