The spatial luminous distribution is very significant to LED products, as we need to check if the luminous intensity distribution or the beam angle or CBCP is conform with the requirement of relevant standards or custom need. These quantities are measured by a goniophotometer which is constitute of a goniometer and a photometer.

Meanwhile, the spatial color non-uniformity of LED product are usually a problem, it would affect the final lighting effect very much. The Energy Star Criteria both for lamps and luminaires have strict specifications, thus we need to accurately measure it with a goniospectroradiometer which is constitute of a goniometer and an array spectroradiometer.

Metrue have two types of Goniophotometer & Goniospectroradiometer for LED products of general lighting purpose.

MGO-300R Goniophotometer & Goniospectroradiometer

MGO-300R is a type C goniophotometer and fully meets the requirements of LM-75 and LM-79, etc.. It is specially designed for professional labs. And it has high accuracy and many measurement functions so as to fulfill the requests of various kinds of lamps and luminaires.

 

 

MGO-200H Goniophotometer & Goniospectroradiometer

MGO-200H can realize both CIE B-β and C-γ measurement solutions which are most widely applied in industrial labs. MGO-200H has simple but robust mechanical structure, and the the operation is very convenient due to its systemic design. In MGO-200H system, the goniometer has high angle accuracy while the photosensor’s accuracy is also good.

 

Both the LED itself and the circuit including driver, are very sensitive to electromagnetic interference. Metrue can provide a series of instrument for the EMC immunity test.

Conform to the standards as IEC 61000-4-2, ISO 10605, MIL-STD-883E, etc..

 

 

Conform to the standards as IEC61000-­­4-5, IEC 60255-5, IEC 61643.1, UL 1449, etc..

 

 

Conform to the standards as CISPR 11, CISPR 14, IEC 60601-1, IEC 60947, IEC 61000-4-4, etc..

 

Conform to the standards as IEC61000-­­4-11, IEC61000-­­4-34, IEC61000-­­4-1, etc..

 

Metrue provides the professional and turnkey test & measurement instrument solutions for LED modules, arrays engines, lamps and luminaires so as to realize the photometric and electrical measurement as per LM-79 and relevant standards.

 

Meet the specifications of CIE and IES standards, eg. CIE 84, LM-79, LM-65.

The system provides quick measurement of Spectral Power Distribution (SPD), luminous flux, luminous efficacy, chromaticity coordinate (x,y), (u’, v’), Correlated Color Temperature (CCT), Color Rendering Index (CRI), Standard Deviation of Color Matching(SDCM), as well as voltage, current, power, power factor, harmonics etc..

Both AC and DC power LED products are applicable.
