Introduction:

Luminous intensity measured in full-space distribution is a key factor in evaluating the performance of light sources in terms of their uniformity and directionality. The LISUN LSG-6000 LM-79 Moving Detector Goniophotometer (Mirror Type C) is an advanced instrument designed to measure the luminous intensity of light sources, particularly in full-space distribution, with precision and accuracy. This paper will explore the principles behind full-space luminous intensity measurement and the capabilities of the LISUN LSG-6000 in conducting such tests.

Principle of Full-Space Luminous Intensity Measurement:

Luminous intensity is the amount of light emitted by a source in a particular direction per unit of solid angle. When measuring luminous intensity in full-space distribution, the total emission pattern of the light source is recorded, allowing for a complete analysis of how light is distributed across different angles. This method is essential for testing lamps, LEDs, and other light-emitting devices in compliance with industry standards like LM-79.

The LISUN LSG-6000 goniophotometer measures luminous intensity by capturing the light emitted by the source across a full 360-degree spherical distribution. The system uses an array of sensors and mirrors to detect light intensity in different directions. The data collected by the goniophotometer is then used to calculate the total luminous flux, light distribution, and other key parameters.
