AUTOMATED INTEGRATING SPHERE PHOTOMETRY TEST SYSTEM

An integrating sphere (also known as an Ulbricht sphere) is an optical component consisting of a hollow spherical cavity with its interior covered with a diffuse white reflective coating, with small holes for entrance and exit ports. Its relevant property is a uniform scattering or diffusing effect. Light rays incident on any point on the inner surface are, by multiple scattering reflections, distributed equally to all other points.

PHOTOMETRIC TEST SYSTEM to measure electrical, luminous and color co-ordinate values, color temperature of LED light sources consisting of  Photometric Integrator and Photometric Control panel as per IS: 16106: 2012,16102(Part 2) : 2012 and LM-79 specification.

 

2.0 Meter Photometric Integrator with Completely Automated Control Panel: (Globe) spherical type to `` measure lumen output of LED lamp or Luminaire or any light product with built-in Spectrometer , baffle screen, window etc. fabricated on fiberglass material, half - half opening type with provision to fix LED lamp, LED street light, LED luminaire of different types with inside special painted Baso4, system conforms as per IS 16106 : 2012,16102, 10322, LM-79 IEC specification.

 `

Photometric Control Panel (Automated Computerized): to measure electrical, luminous and colour co-ordinate values, color temperature of LED light sourrces using the above Photometric Integrator, with incorporating spectral sensor, Digital Power Meter , temperature indicator to measure integrator inside temperature, Variac transformer for output fine tuning etc., and other switches & controls.

 

The print-out gives various parameters of lamps such as V1 (supply volt) – Amp – Watt – Hz– Lux-Lumen – ‘x’ – ‘y’ color co-ordinate values, color temperature etc., in a single operation.  Also provision to get the print out of ‘V’ harmonic, ‘I’ harmonic and total harmonic values etc.,
