The Fluorescent Lamp Lighting for Television Studio

Television slit-lamp biomicroscopy.

The basic requirements for performing television slit-lamp biomicroscopy are outlined, and the methods of demonstrating particular features of ocular anatomy and ocular disease are discussed. The technique has a particular role in teaching in the clinical setting.

High Frequency Resonant Inverter for Group Dimming Control of Fluorescent Lamp Lighting Systems

Fluorescen t power SUPPlY Dimmer I Electronic bal last I Lamp IAn electronic ballast for fluorescent lamp lighting using a new resonant inverter is proposed. The electronic ballast has high efficiency, light wcight and small sizc bccause the resonant inverter operates at high frequencies with low switching losses. The inverter output power can be continuously controlled by regulating the L-C re...

Revisiting the performance and mood effects of information about lighting and fluorescent lamp type

Popular articles and manufacturers’ literature assert that full-spectrum fluorescent lighting improves cognitive performance, vision, and mood. Previous experimental investigations have failed to demonstrate these effects. This paper reports an attempt to replicate work by Veitch, Gifford, and Hine (1991) concerning the effects of information sets about lighting on performance and mood. In this...

Comparing colour discrimination and proofreading performance under compact fluorescent and halogen lamp lighting.

UNLABELLED Legislation in many countries has banned inefficient household lighting. Consequently, classic incandescent lamps have to be replaced by more efficient alternatives such as halogen and compact fluorescent lamps (CFL). Alternatives differ in their spectral power distributions, implying colour-rendering differences. Participants performed a colour discrimination task - the Farnsworth-M...
