Lisun goniophotometer is coming for all kinds of lighting sources

Lisun goniophotometer is coming for all kinds of lighting sources!The full determination of the data of luminaires and lamps becomes more and more important.

The lisungroup goniophotometer have realized measuring devices according to the desired range of the measuring objects and also according to the available laboratory space.

Utilized a new image-resolving CCD measuring technique for determining ray data and luminous intensity distributions,the Lisun goniophotomete correctly determinate the luminous intensity distributions (Lid) of lamps and luminaires .What's more the Lisun goniophotometer can also  performed far within their photometric limiting distance on the basis of image-resolved measurements of luminous intensity distributions.

Integrating Spheres from the Lisun Group – We bring quality to light

Integrating Spheres from the Lisun Group (Hong Kong) limited– We bring quality to light ,

Lisun Group designs and manufactures a variety of good quality integrating spheres and accessories for photometric and radiometric applications.  Our spheres are available in a variety of sizes to offer customers the most flexibility when choosing a sphere for their application. The spheres are extremely robust yet are surprisingly lightweight, compact, and easy to operate.

Goniophotometers from the Lisun Group (Hong Kong) limited– We bring quality to light,combined with

a full range of the art photometers, colorimeters, radiometric application and other accessories –  corrected and automated measurement of the brightness  – luminous intensity , illuminance , luminous flux (lumen), retro-reflectivity (mcd/lx), color coordinates from optical radiation sources.

Our goniophotometers are used in the design, develop?ment, production QA testing of lamps and luminaires and in the certification of the final product accoding to relevant international and national regulations, standards and publications such as UN-ECE, SAE, FMVSS108, DIN-EN, CIE, ICAO, FAA, ASTM and others.

There are two types of photometers

There are two types of photometers: spectrophotometer and filter photometer. A monochromator (with prism or with grating) in spectrophotometers is used to gain monochromatic light of one defined wavelength. In filter photometers, optical filters are used to provide the monochromatic light. Spectrophotometers can thus easily be set to measure the absorbance at different wavelengths, and they can also be used to scan the spectrum of the absorbing substance. They are in this way more flexible than filter photometers, also give a higher optical purity of the analyzing light, and therefore they are preferably used for research purposes.

Goniophotometer

A Goniophotometer is equipment used for measurement of the light emitted from an object at different angles. The application of goniophotometers has been increasing in recent years with the introduction of LED-light sources, which are mostly directed light sources, where the spatial distribution of light is not homogeneous. Due to strict regulations, the spatial distribution of light is of high importance to automotive lighting and its design.
