Abstract
A light emitting device disclosed herein includes a light source and component thermally coupled to the component. The device further includes a lightguide formed from a film. The lightguide includes an array of strips extending from an area of the film. The array of strips is positioned adjacent the array of protruding teeth, the component thermally conducts heat from the light source, and the component at least partially restrains the film relative to the component.
Claims20
A light emitting device comprising:
- a component having a frame;
- a light source thermally coupled to the component;
- and
- a lightguide formed from a film, the lightguide comprising an array of strips extending from an area of the film, the array of strips are positioned along an edge of the component, each strip of the array of strips is folded in a fold region such that ends of the strips are stacked and positioned to receive light from the light source, wherein the film is at least partially restrained relative to the component and the component is a thermal transfer element that conducts heats from the light source.

A light emitting device comprising:
- a component elongated with a dimension in a first direction at least twice as long as a dimension in either mutually orthogonal directions orthogonal to the first direction;
- a lightguide formed from a film, the lightguide comprising an array of strips extending from an area of the film, the array of strips is positioned along an edge of the component, each strip of the array of strips is folded in a fold region, and a portion of the lightguide is attached to the component or restrained by the component;
- and
- a light source thermally coupled to the component and positioned to emit light that propagates into ends of the array of strips, wherein the component is a thermal transfer element that conducts heat from the light source.

A light emitting device comprising:
- a lightguide comprising a linear array of strips extending from an area of a film;
- a component positioned adjacent the linear array of strips, a portion of the lightguide is attached to the component or restrained by the component, and the linear array of strips are folded in a fold region and aligned over each other to form a folded array of strips;
- and
- a light emitting diode coupled to the component and positioned to emit light into ends of the folded array of strips, wherein the component is a thermal transfer element that conducts heats from the light emitting diode.
