A light emitting diode (LED) work light and associated method of controlling the LED work light. The LED work light includes a power source, a casing including a handle section, at least one LED mounted to illuminate light from the casing, at least one lens forward of the LEDs to focus light from the LEDs, a control switch designated to at least turn on and turn off the LEDs, and a controller. The controller may be configured to, in response to activation of the control switch, provide control of the power source to the LEDs to transition from a first illumination state to a second illumination state of the illumination of the LEDs, the transition being illumination defined by a specified function over time defined to slow a transition time of the transition.

LED work light

A light comprising an LED whose light intensity decreases as the angle from an axis of the LED increases, and a convex lens associated with the LED such that a beam width of the LED is concentrated by the lens into a narrower beam width, wherein the convex lens includes both a convex surface and a concave surface, and the concave surface is curved more sharply towards its edge than towards its center such that light is more evenly spread across the beam width of the lens.

Work light has LEDs that require heatsink. Desired radiation pattern achieved by using optical components designed to produce beam or LEDs may have beams in different directions. Radiation pattern of LEDs may be changed by refractive-reflective optics or by convex lenses. Convex lenses may be hemispheres, other planoconvex shapes, concavo-convex shapes, or other shapes. Curved surfaces on any lenses may be spherical or aspheric. Ballast to operate the LEDs from line voltage AC or low voltage DC. Work light may contain batteries. The work light may be mounted on a stand. May have accessory mount. May have charging station. May have a paging transmitter to activate a paging receiver in work light. May have openings for heat transfer from heatsink to ambient air external to light.
