Abstract
An LED spotlight is made with at least one light emitting diode and a lens placed forward of the light emitting diode to collimate the light from the light emitting diode into a beam. The light emitting diode is preferably a type with a nominal power of at least 1 watt, requiring heatsinking, and having a nominal radiation pattern width of 100 degrees or more. The lens is preferably concavo-convex. The lens can have a thickness less than the distance between the rear surface of the lens and the light emitting diode. The LED spotlight can be mounted on headwear that would be worn on a person's head. The LED spotlight can be in the form of a flashlight. The LED spotlight can be in the form of an inspection lamp suitable for causing visible fluorescence of fluorescent materials, such as leaks of fluids that have suitable fluorescent dyes.
