Abstract:
An electronic device includes a substrate having a primary surface, an array lying along the primary surface, wherein the array includes one or more radiation-emitting components, one or more radiation-responsive components, or any combination thereof, and a first edge connector. In a direction parallel to the primary surface, the first edge connector lies between the array and a perimeter of the substrate. In one embodiment, the electronic device is designed, such that during normal operation, the first edge connector has a temperature difference, due to current flow through the first edge connector, of no more than 10° C. In another embodiment, the array has an emission homogeneity of at least 75% over a lifetime of the electronic device. The electronic device can be operated with good emission intensity and have an extended electronic device lifetime compared to an electronic device having edge connectors that can cause local heating.

Abstract:
The present invention relates an optical sensor. In particular, the present invention relates to an optical sensor for detecting chemical components in a fluid.The present invention comprises two or more sensors, each being configured to detect one or more chemicals in a fluid, or one or more properties of the fluid, and two or more light sources. Each sensor is associated with one light source, and each sensor is configured to emit or reflect light in response to light from the light source incident on the sensor. The emitted or reflected light is dependent upon the presence of a chemical or a property of the fluid. The two or more light sources and two or more sensors are arranged around a single light detector, which detects the color and/or intensity of the light being emitted or reflected by the sensor. Data from the light detector is passed to a remote processor for processing.
