摘要:
The invention provides an interconnected string of three LED modules, having internal and external connections such that each LED in the string is fully individually addressable. LED biases and interconnects are oriented and configured such that individual addressability is achieved without the need for direct external signal connections to each LED in the string. Consequently embodiments are provided comprising pluralities of strings, arranged so as to form an array of LED modules, wherein wiring tracks running beneath, or along the intermediary spaces between, rows of LEDs are not required. Hence are provided LED devices comprising an array of individually addressable LED modules, having reduced spacing between rows and columns, and having optimal thermal path perpendicularly across the substrate layer. Provided devices have improved heat dissipation and greater achievable LED array density. Also provided are embodiments comprising one or more lens arrangements, suitable, for example, for adaptive beam-shaping applications.

Eine transportable Leuchtvorrichtung weist eine Leuchteinrichtung (1), eine die Leuchteinrichtung (1) tragende, sich in einer Längsrichtung erstreckende Säuleneinrichtung (4) und eine die Säuleneinrichtung (4) tragende Stativeinrichtung (6) auf. An der Leuchtvorrichtung ist ein ein Leuchtmittel umschließender Leuchtenschirm (2) vorgesehen, der auf seiner Innenseite durch Biegestäbe (13) aufgespannt ist. Die Biegestäbe (13) sind mit Hilfe von Gelenkstücken (14) an jeweiligen Halterungen (11, 12) verschwenkbar befestigt. Die Biegestäbe (13) sind mit Hilfe einer formschlüssigen Verbindung in den jeweiligen Gelenkstücken (14) gehalten.
摘要:
A LED circuit comprises an array of LEDs is arranged in a matrix. The matrix is connected to at least three power rail lines. The LEDs are formed as a first LED arrangement (34) between a first power rail line (30) and a second power rail line (32) and a second LED arrangement (36) between the second power rail line (32) and a third power rail line (30) of the same voltage as the first power rail line. This means there are alternating power rail lines interspersed with the matrix of LEDs. This enables the driving voltages to be kept low and it improves scalability of the design.

The invention relates to a lighting device (1) for generating white light which has at least one strip of three light diodes (LEDs) (2) in a linear arrangement, wherein: a) each LED strip (2) has two outer LEDs (3) and one center LED (4); b) each of the two outer LEDs (3) and the center LED (4) are phosphor-converted white LEDs; and c) the distance of each of the color coordinates of the two outer LEDs to the color coordinates of the mixed light of the two outer LEDs and the center LED is smaller than the distance of the color coordinate of the center LED to the color coordinates of the mixed light of the two outer LEDs.
摘要:
A lighting fixture is presented comprising a plurality of modular apparatuses wherein each modular apparatus comprises one or more light sources and one or more light directing or light redirecting devices. Methods of adjusting one or more components of said lighting fixture about one, two, or three axes are presented whereby the lighting needs of a target area—even one of complex shape—may be addressed and in a manner that promotes compact fixture design with low effective projected area (EPA) without sacrificing transmission efficiency of the light sources.
