摘要： The systems herein include a support structure and multiple light sources mounted to the support structure. The light sources are configured to project light onto a recording stage to light a specified video scene that is to be recorded on the recording stage. These systems also include a perforated layer that includes an arrangement of apertures. The perforated layer has an inward face directed toward the lighting sources and an outward face directed toward the recording stage. The inward face of the perforated layer includes a surface layer that is more reflective than the surface layer of the outward face of the perforated layer. These systems also include a controller that modifies the light emission profile of the light sources, including changing color balance, brightness, time dependence, and/or spatial variation over the light emissive surface of the light sources. Various other apparatuses and recording stage devices are also disclosed.

摘要： An illuminator has an elongate tubular body containing LEDs on a substrate and a lens forming a bridge over the LEDs. The tubular housing has a transparent top part to act as an outer lens and diffuser. The housing is connected at each end to an end cap via a resilient seal which is moulded into the end cap. The internal lens is compact and provides a versatile choice of illuminator configuration for desired illumination. A convex curved lower lens s profile ensures efficient transmission of emitted light without colour separation. The extent of sealing is very short due to the closed tube nature of the housing and the short perimeters for sealing of the ends of the body to the end caps.
