Limitation of luminous for street lighting luminaires

Hammer Testing Findings for Solid-State Lighting Luminaires

Street Lighting Disturbs Commuting Bats

Anthropogenic disturbance is a major cause of worldwide declines in biodiversity. Understanding the implications of this disturbance for species and populations is crucial for conservation biologists wishing to mitigate negative effects. Anthropogenic light pollution is an increasing global problem, affecting ecological interactions across a range of taxa and impacting negatively upon critical ...

An accelerated test method of luminous flux depreciation for LED luminaires and lamps

Light Emitting Diode (LED) luminaires and lamps are energy-saving and environmental friendly alternatives to traditional lighting products. However, current luminous flux depreciation test at luminaire and lamp level requires a minimum of 6000 h testing, which is even longer than the product development cycle time. This paper develops an accelerated test method for luminous flux depreciation to...

Discussion of "Electrocution by Street Lighting".

Luminaires: Linear Fluorescent Luminaires

A large portion of the commercial and industrial lighting systems currently in use was put in place between 1960 and 1990, according to statistics. The systems that are in place often rely on the use of manually controlled incandescent and standard fluorescent lighting with magnetic ballasts, or even mercury vapor systems. These types of lighting systems and lighting controls are generally less...
