Abstract
A dynamic light source for a display is disclosed. The dynamic light source comprises a first light source located inside a first device; and a second light source. The first device is configured to allow light from the first light source to exit the first device in a first cone of angles and to reflect light incident outside the cone of angles back towards the first light source. The first device is configured such that injected light from the second light source is reflected by the first light source in a second cone of angles substantially coincident with the first cone of angles and that light output by the first device from the second light source is attenuated more than light output by the first light source, and an amount of attenuation is based on an intended dynamic power range of the dynamic light source.
