A total internal reflective (TIR) optic light bar of a lighting fixture configured to illuminate an object, such as a two-dimensional planar surface, the optic light bar including a body having a first end portion that extends to a second end portion through an elongated intermediate portion, the body including a light input surface extending between the first and second end portions, a total internal reflective (TIR) surface, and at least one light output surface, where the light output surface is formed as a gradual, continuous curve including a plurality of discrete segments that form a curvilinear surface, and where the TIR surface is composed of one or more of the discrete segments which form the curvilinear light output surface.

A total internal reflective (TIR) optic light bar includes a body having a first end portion that extends to a second end portion through an elongated intermediate portion. The body includes a light input surface having a curvilinear profile, a total internal reflective (TIR) surface, and at least one light output surface. The light input surface, TIR surface, and at least one light output surface defining a continuous outer surface of the body.

A photonic structure for 'white' light generation by phosphors under the excitation of a LED. The photonic structure mounts the LED and an optically transparent nanocomposite matrix having dispersed therein phosphors which will emit light under the excitation of the radiation of the LED. The phosphors dispersed in the matrix may be nanocrystalline, or larger sized with the addition of non light emitting, non light scattering nanoparticles dispersed within the matrix material so as to match the index of refraction of the matrix material to that of the phosphors. The nanocomposite matrix material may be readily formed by molding and formed into a variety of shapes including lenses for focusing the emitted light. A large number of the photonic structures may be arranged on a substrate to provide even illumination or other purposes.

A flip chip light emitting diode die (&#x2033;) includes a light-transmissive substrate (&#x2033;) and semiconductor layers (&#x2033;) that are selectively patterned to define a device mesa (&#x2033;). A reflective electrode (&#x2033;) is disposed on the device mesa (&#x2033;). The reflective electrode (&#x2033;) includes a light-transmissive insulating grid () disposed over the device mesa (&#x2033;), an ohmic material () disposed at openings of the insulating grid () and making ohmic contact with the device mesa (&#x2033;), and an electrically conductive reflective film (&#x2033;) disposed over the insulating grid () and the ohmic material (). The electrically conductive reflective film (&#x2033;) electrically communicates with the ohmic material ().

A photonic structure for &ldquo;white&rdquo; light generation by phosphors under the excitation of a LED. The photonic structure mounts the LED and an optically transparent matrix having dispersed therein phosphors which will emit light under the excitation of the radiation of the LED. The transparent matrix may include nanoparticles for matching the index of refraction of the material of the matrix to that of the light generating phosphors. The matrix material may be readily formed by molding and formed into a variety of shapes including lenses for focusing the emitted light. A large number of the photonic structures may be arranged on a substrate to provide even illumination or other purposes. The phosphors dispersed in the matrix are preferably nanocrystalline.

An X-ray imaging system utilizing a pixelated X-ray source and a X-ray imaging detector operated synchronously. The imaging system may be used in industrial and medical applications. The X-ray source and X-ray detector are synchronized such that a corresponding area of the X-ray detector is activated when the corresponding area of the X-ray source is emitting X-rays. Synchronized and adaptive emission and detection of the X-rays results in scatter rejection, improved image quality, and optimum exposure and dose reduction.
