If you live in an older home or simply have a penchant for antiques, you may occasionally spot these once-popular relics we ...

The lighting industry’s benchmark for the end of service life is defined as when LED output drops to 70% of its initial ...

This paper presents an improved semitheoretical fluorescent lamp model by including the effect of the lamp tube temperature on the lamp electrical parameters at different dimming levels. The ...

Wearable visible light communication systems face fundamental limitations in dense multi-input multioutput configurations due to signal crosstalk between channels. Here, we demonstrate shear-aligned ...

Two red fluorophores (TPABTPA and TPABCHO) with hybridized local and charge-transfer properties were systematically studied. TPABTPA and TPABCHO enabled nondoped organic light-emitting diodes (OLEDs) ...
