LSG-1800 Goniophotometric system is an automatic goniophotometric measurement system for measuring photometric parameters of luminaires, such as LED road lighting fixture, room lighting fixture and projecting lighting fixture. The measured data meets IES standard format and can be applied for lighting design by lighting design software. The measurement system fully satisfy the requirement of lighting design work.

LSG-1800B Goniophotometer system is a update version of LSG-1800. The LSG-1800B have a constant temperature detector, and use luminous intensity standard lamp to calibrate the system. Lisun develop a new software to run LSG-1800B.

Measures:
Electronic parameters, spatial intensity distribution curve, spatial iso-intensity curve, iso-illuminance distribution curve, luminance limitation curve, luminaire efficiency, glare grade, effective beam angle, upward luminous flux ratio, downward luminous flux ratio, total luminous flux, effective luminous flux, utilization factor.

Features:
• Reaching many measurement ways such as B-β, A-α and C-γ
• Can be drived by both double pillars and single pillar
• Special laser cross aim device makes the installation of luminaire
• The special rotating electric devices for lighting the tested luminaire
• Provided with the precious metal fiber for signal transmission
• Measured data match with international standard form (IES) and can be applied for lighting design by other lighting design software such as Dialux
• Emergency stop function
• RS-232C interface, compatible with all kinds of computers
• Meets the requirements of IEC, CIE and LM-79 standards 
 

Products of this category:
LSG-2000: Mirror on optical axis. When measuring light source, the holder for light source has to move in a large space during the measurement.
LSG-1900: Lamp on optical axis. It overcomes the problem of instability of the tested light source when measuring light intensity. 
LSG-1800: With facility of double arms for turning the light source. When doing light measurement, the long measuring distance can easily be achieved.
LSG-1600: With facility of single arm for turning the light source when doing the measurement of light.
LSG-1200: The compact one is the best way for light intensity measurement of small or weak sources.
LSG-880: This goniophotometer is the best answer of how to measure light of LED cup lamp or spotlight.
