Abstract
An LED reading light assembly has an optical assembly, a power circuit board, a housing, and a control system. The optical assembly includes a holographic lens and an LED assembly comprising an LED circuit board and a plurality of LED's disposed on the outward facing side of the LED circuit board. The power circuit board provides a constant source of electric current to power the LED's. The housing includes a housing plate disposed behind the LED circuit board and a black anodized fin plate. The control system includes a temperature protection circuit monitoring the ambient temperature at the LED assembly during operation and adjusting the power supplied to the LED's to maintain the ambient temperature within a selected temperature range.
