Abstract: An illuminating unit includes at least two modules, wherein each module includes a housing and a light-emitting device that is fixed to the housing, each housing includes beam forming optics, each housing includes four side walls, the first side wall includes a first mechanical connector, the second side wall includes a second mechanical connector, the first mechanical connector of the first module connects with the second mechanical connector of the second module, and the first side wall and the second side wall of the housings of the first and second module have the same shape.

Abstract: In at least one embodiment, the light guide (10) comprises a single-pieced light guide body (1). The light guide body (1) includes a transparent material and a light entrance segment (2) having a first cross-section (11) with a polygonal shape. Furthermore, the light guide body (1) includes a light output segment (4) having a second cross-section (22) with a rotund, round, circular, oval or elliptic shape. A transition segment (3) is arranged adjacent to and between the light entrance segment (2) and the light output segment (4). Along the transition segment (3), the first cross-section (11) in particular continuously changes to the second cross-section (22).

Abstract: The present invention provides mathematical model-based incremental clustering methods for classifying sets of data and predicting new data values, based upon the concepts of similarity and cohesion. In order to increase processing efficiency, these methods employ weighted attribute relevance in building unbiased classification trees and sum pairing to reduce the number of nodes visited when performing classification or prediction operations. In order to increase prediction accuracy, these methods employ weighted voting over each value of target attributes to calculate a prediction profile. The present invention also allows an operator to determine the importance of attributes and reconstitute classification trees without those attributes deemed unimportant to further increase classification structure node processing efficiency.

Abstract: A LED bulb and light module utilizes a LED light source and directs light therefrom in a manner which improves efficiency and illumination. Ideally, the LED bulb is structured to create a virtual image whereby the efficiency of light directed out of the module is greatly improved, even with a single LED light source.
