摘要:
Methods of controlling a backlight unit including a plurality of solid state light emitting devices include receiving a request to set a color point of the backlight unit at a requested color point, and determining if the requested color point is within an acceptable range. In response to the requested color point being outside the acceptable range, a modified color point is selected in response to the requested color point, and a color point of the backlight unit is set at the modified color point. Corresponding solid state lighting units are also disclosed.
