Abstract
Light fixtures (100, 200, 400, 500, 600, 700) are provided, including a lighting element (10, 20, 40, 50, 60, 70), an oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72) disposed adjacent to or connected to the lighting element, and a control mechanism (14, 24, 44, 64, 74). The control mechanism is in electrical communication with the lighting element (10, 20, 40, 50, 60, 70) and controls an energy output of the lighting element and a temperature of the oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72). Typically, when the control mechanism changes the temperature of the oriented crosslinked semi-crystalline polymer, the shape of the polymer changes. A method of making a light fixture (100, 200, 400, 500, 600, 700) is also provided. The method includes providing a lighting element (10, 20, 40, 50, 60, 70), forming a crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72), and disposing the crosslinked semi-crystalline polymer adjacent to the lighting element (10, 20, 40, 50, 60, 70) or connecting the crosslinked semi-crystalline polymer to the lighting element. The method further includes electrically connecting a control mechanism (14,…
