LPV-4 LED Transmissometer

摘要

A new LED transmitter for the Optec Transmissometer has been successfully developed, tested, and deployed in urban visibility monitoring programs (Denver, Fort Collins, Phoenix) and the solar energy industry (Ivanpah & Israel). The LED transmitter has reduced power requirements, removed the need to have multiple calibrated lamps for a year of operation, eliminated data loss due to chopper motor failures, and eliminated the lamp brightening issue.
