A study on overhead glare in office lighting conditions.

The article discusses the results of a study that evaluates the overhead glare of the light-emitting diode (LED) luminaire in the workplace environment. It examines the LED's perceived overhead glare at various luminance levels and at different angles. The study shows that the LED luminaire consisting of a matrix of high-intensity point sources may cause overhead glare. It concludes that a point-array LED lighting generates more overhead glare than uniform lighting sources.
