Embodiment Construction

[0038] Figure 3(a) shows an arrangement 100 of light emitting diodes employed by a lighting system according to an embodiment of the present invention. The lighting system includes a plurality of conductive branches configured to form a three-dimensional arrangement. It should be noted that, in various embodiments of the present invention, the arrangement may be configured such that each LED is arranged on the display screen.

[0039]In the embodiment shown, the lighting system comprises three branches and has a triangular cross-section. Figure 3(b) also shows such a triangular section, but the invention is not limited to this extent. Each branch 102(a), 102(b) and 102(c) of FIG. 3(a) is denoted as a branch end node 102(a), 102(b) and 102( c). Figure 3(c) shows another embodiment in which the triangular section is repeated on each side, so that three additional triangular sections are formed, that is to say a total of six branches, wherein the The ends are indicated by bra...

Abstract

A lighting system comprising a plurality of light-emitting diodes and a power supply source for driving current through a plurality of parallel disposed, electrically conductive branches, wherein the branches comprise at least one cell. The branches are configured to display the light-emitting diodes according to a three-dimensional arrangement. In each cell, each branch has a light-emitting diode with an anode terminal and a cathode terminal. The anode terminal of each light-emitting diode is coupled to the cathode terminal of a light-emitting diode of an adjacent branch via a shunt. The shunt further comprises a light-emitting diode. In each cell, each light-emitting diode may have a different forward voltage characteristic, while still insuring that all of the light-emitting diodes in the arrangement have the same brightness. Upon failure of one light-emitting diode in a cell, the remaining light-emitting diodes in the same cell are not extinguished and, in a multiple cell embodiment, the light-emitting diodes in the successive cells are not extinguished.

Description

technical field [0001] The present invention generally relates to lighting systems, and more particularly to an improved three-dimensional light-emitting diode array structure used as a lighting source. Background technique [0002] A light emitting diode (LED) is a semiconductor device, more precisely, a p-n junction through which an electric current flows to generate electromagnetic radiation. Light-emitting diodes usually contain semiconductor materials with a suitable mixture of gallium-arsenic-phosphorus. By changing the ratio of phosphorus and arsenic, the wavelength of light-emitting diodes can be adjusted. [0003] With the advancement of semiconductor materials and optical technology, light-emitting diodes are increasingly used for lighting. For example, high-brightness light-emitting diodes are now used in car signals, traffic lights and signals, and large-area display screens. In these applications, multiple LEDs are connected in an array structure to generate ...
