LED Solar Simulation Technologies (Pages 50–53)

Page 50–53. A solar, or sun simulator, is an artificial system designed to accurately replicate the spectral distribution and illuminance of natural sunlight. There are different types of solar simulator, each with technical specifications designed to fit particular applications. The various types are often separated by the type of exposure in use—flashed, continuous, and pulsed. As new scientific advances were made, attention shifted from the standard halogen and xenon lamps. We have entered...

Excimer: The Technology Explained

The term excimer refers to a temporary atomic state in which high-energy atoms form short-lived molecular pairs, or dimers, when electronically excited. These pairs are called excited dimers. As the excited dimers return to their original state, the residual energy is released as a ultraviolet C (UVC) photon. In the 1960s, a new portmanteau, excimer, emerged from the science community and became the accepted term for describing excited dimers. By definition, the term excimer refers...

Beauty is in the Diode of the Beholder

Optical food sorting: fluorescent lamps provided powerful visible light illumination, while halogen introduced infrared wavelengths to the application. These processes gradually improved as food safety awareness increased and the arrival of a globalised market that demanded easy access to fresh produce from around the world. Fast forward just shy of 90 years and we have entered an era of 100% non-destructive, non-invasive, fully-traceable optical sorting – thanks, in no small part, to the...
Blood, sweat, and tears: the innovation behind multi-wavelength LEDs

When applications call for a higher multi-colour output power, such as automatic number plate recognition (ANPR), Ushio designs and manufactures customised multi-chip SMBB packages and EDC LEDs where a smaller footprint is required. Additionally, photodiodes can be integrated into the customised packages to allow sensory measurement and analysis alongside the light emitting capabilities. Other customisable options include package shape, type, and number of light emitting chips.
