    摘要: An optical navigation devices and methods that utilize an internal reflection surface to reflect and collimate sidelight from a light source are described. A light source is configured to emit light. The sidelight from the light source is reflected and collimated by an internal reflection surface towards a work surface. The light received by the sensor is used to measure movement of the optical navigation device relative to the work surface.

    摘要: A light emitting diode, a reflector and a platform are employed within a light source. The light emitting diode emits light exclusively from its side surfaces. The reflector has a parabolic reflective surface that collimates any portion of the light reflecting from the parabolic reflective surface. The platform supports a centering of the light emitting layer(s) of the light emitting diode on a focus point of the parabolic reflective surface.

    摘要: The light-emitting device includes a light source and a gradient index (GRIN) element. The GRIN element has a cylindrical refractive index profile in which the refractive index varies radially and is substantially constant axially. The GRIN element includes a first end surface opposite a second end surface and is characterized by a length-to-pitch ratio. The GRIN element is arranged with the first end surface adjacent the light source to receive light from the light source, and emits the light from the second end surface in a radiation pattern dependent on the length-to-pitch ratio. Since the radiation pattern depends on the length-to-pitch ratio of the GRIN element, LEDs with different radiation patterns can be made simply by using GRIN elements of appropriate lengths.
