Compact Near Field Goniophotometer For IES LDT File Test
Compact Near Field Goniophotometer For IES LDT File Test The compact goniophotometer of LSG-1200A is used to measure the luminous intensity distribution curve,Website:, intensity data, spread angle and other parameters for Chip LED, LED Module, LED Spotlight and all other light which beam angle is no more than 180 degree.Option Function: The LSG-1200A can work with a Digital Power Meter (LS2012 DC & AC Power Meter or LS2010 Harmonic Analyzer) and LSP-500VA AC Power Source. Specification:
• Meets the requirements of IEC, CIE and LM-79 standards
• Measures beam angle automatically: staple half intensity angle as well as 1/4 intensity angle, 3/4 intensity angle and 1/10 intensity angle which meets the special requirements.
• Measured data is matched with international standard form (IES) and can be applied for lighting design by other lighting design software such as DiaLux
• LSG-1200A has included a dark room, measures the maximum size of lamps: 180mm
• Test range of luminosity: 0.1～30,000lx. Test accuracy of detector: Class 1
• The distance between the tested lamp and detector is 316mm/1000mm
• Angle interval: Horizontal angle: 1°/5°/10°/15°/22.5°/30°/45°/90°, Vertical angle: 0.5°/2°/1.5°
• The LSG-1200A horizontal automatic rotating on 0°~360° and Vertical automatic rotating on -90°~+90°
• Test accuracy of angle: ±0.2°.
