Metrology Upgrading Programme - Optical measurement of LED Lighting


Course Outline

LEDs are increasingly being used as general illumination sources due to their high efficiency and durability. The lighting principle of LED is different from traditional light sources such as incandescent light bulb and fluorescent tubes. The optical measurements of these light sources are more difficult than others. This course aims to provide participants with the knowledge of the key factors affecting the measurement accuracy of LED lights. It covers the theoretical and practical aspects of optical measurements for LED lighting. Measurement techniques for luminous flux, spectral irradiance, colour rendering index and spectral mismatch corrections are covered in the course. The laboratory sessions offer the participants an opportunity to understand and verify the knowledge learned.
