A flash system for an electronic device includes a ring-shaped light guide having a central opening. A camera lens is positioned in or behind the opening. A first light emitting diode (“LED”) is mounted on a printed circuit board (“PCB”), and the LED and PCB are encapsulated by a molded light guide of the flash system. An identical LED and PCB are encapsulated at an opposite end of the molded light guide (i.e., 180 degrees away). The back surfaces of each PCB diffusively reflects light from the LED on the other PCB. Light extraction features on the light guide surface uniformly leak out light from the LEDs. The light emission profile of the light guide has a peak axially aligned with the central opening of the light guide and rolls off to the edge of the camera's field of view.

A light-emitting diode (LED) includes s a substrate, a LED chip, and an optical lens. The LED chip is fixedly mounted to the substrate for emitting a light beam. The optical lens is mounted to the substrate and covers the LED chip. The optical lens has a light exit surface, which directs the light beam from the LED chip to travel in a direction along an optical axis to form a non-symmetric light shape. Also disclosed is a surveillance camera device that uses the LED. As such, the drawback of a conventional surveillance camera being incapable of acquiring an excellent image due to light source being overly concentrated can be eliminated.

The innovative systems and methods described herein use a high-resolution imaging microscope for capturing images of marine microorganisms and particles in situ in an aquatic environment. Using darkfield illumination, high-resolution images may be obtained, capturing features of the microorganism or particle as small as 10 μm in remarkable clarity. Utilizing an open flow-through approach in sample imaging, the delicate structures of the plankton and particles may be imaged completely intact without damage and in their natural orientation. The images can be classified at high accuracy based on physiological and morphological in-formation captured in the image including features as fine as 1 μm. The disclosed classification method utilizes adaptable training sets of taxonomic categories and a novel method of discerning in-focus targets, providing a highly accurate identification system.

An illumination device includes first, second, and third light-emitting diode chips arranged around a center axis along virtual outlines of first, second, and third geometric figures, respectively. The geometric figures are concentric. A bond wire is connected to a connection point of each chip in its peripheral region. Multiple groups are defined, with each including one each of the first, second, and third chips. Within a first group, the first, second, and third chips are arranged on first, second, and third virtual rays, respectively. The rays each intersect only a single light-emitting diode chip, are transverse to the center axis, and originate at, and extend outwardly from, the center axis. In the first group, the second chip neighbors the first chip, the third chip neighbors the second chip, and the chips are rotated relative to one another such that the respective connection points are oriented in different directions.

An ornamental frame assembly for enhancing the ornamental appearance of a flat screen display includes a frame that has a plurality of intersecting members such that the frame has a rectangular shape to conform to a flat screen display. Each of the intersecting members comprises a first portion that is oriented at an angle with a second portion to accommodate an outer edge of the flat screen display. A lens is attached to the frame such that the lens extends around a full perimeter of the frame. A plurality of light emitters is each positioned in the frame. Each of the light emitters is positioned behind the lens to emit light through the lens.

One aspect of the present disclosure is an imaging system including an optical sensor defining an optical axis. The system further includes a light source. The system may include an optical beam splitter, and may also include an optional diffusing lens that may be configured to diffuse and/or collimate light from the light source and direct light exiting the diffusing lens to the optical beam splitter. The optical beam splitter is configured to direct light from the light source along the optical axis of the optical sensor.
