Spotlight system for organized event technology, has filament arranged relative to bulb and bulb geometry such that some infrared radiation from filaments are reflected back by bulb to filaments

摘要

The device has a light source (53) that emits radiation with an infrared component and has a lamp bulb (60) that at least partly reflects infrared radiation, at least one filament arranged relative to the bulb and a bulb geometry such that some of the infrared radiation emitted by the at least one filament is reflected back by the bulb to the at least one filament.
