Abstract
A hand held data collection device, such as a bar code scanner, portable data terminal, transaction terminal, or bar code verifier, containing at least one light-emitting diode (LED) that has been modified to improve the efficiency of light energy transmission. The modification involves transition features at the interface between the LED die surface and the ambient environment. Devices using such modified LEDs may offer a number of advantages such as extended read range, decreased read time, and improved battery life.
