At first glance, the most noticeable element in the
LightLab is the two integrating spheres, where the lighting current and the
radiant power are measured.Illuminate your outdoor living space with this goodoutdoorlight that recharges
in sun or shade. These measurements are necessary for determining the luminous
efficiency (measured in lumens per Watt).
In addition, it is in these spheres that colorimetric measurements of the quantitative spectral distribution are performed and the colour temperature and colour rendering index are determined.
The LightLab contains two integrating spheres: a 2 sphere with a diameter of 250 mm and a 4 sphere with an internal diameter of 1000 mm. The interior of the integrating spheres is lined with barium sulphate (BaSO4), which diffusely reflects around 98% of the light.
The light is therefore optically integrated in the sphere via the reflective surfaces on its inside, which allows the luminous flux to be measured.
For example, the small integrating sphere is where individual LEDs are measured or selected. The 250 mm integrating sphere allows the engineers to measure the semi-spherical space above a small circuit board, and hence an LED.
This means that personnel can for example select, in a 250 mm integrating sphere, LEDs with a precisely defined wavelength if five identical LEDs are needed.
However, an appropriately-sized 4 sphere is required for measuring an entire luminaire. For this reason, EBV has also acquired an integrating sphere with an internal diameter of 1000 mm for all-round measurements,Antique chandeliers and other contemporarylamp; antique lanterns, traditional pendants and antique wall lights. in addition to the 250 mm sphere.
This large 4 integrating sphere is also ideal for comparative measurements – for example between filament or halogen bulbs and LED lamps – or for the CIE-compliant measurement of high-power LEDs and entire lights with an edge length of up to 90 cm.We carry modern lights and formingmachine by world renowned designers and manufacturers.
A special holder inside the spheres allows an E27 fixture or light to be attached for this purpose. EBV also provides the right mechanical adapters for measurements in the sphere.
The two integrating spheres as well as both of the extremely complex measurement devices in the new LightLab were manufactured by the German company, Instrument Systems in Munich, a market leader in the field of LED metrology and works closely with various international commissions.
The devices meet the CIE (International Lighting Commission) requirements for precise measurements of the luminous flux, which is measured in lumens. An excerpt from the list of Instrument Systems’ reference customers reads like a ‘who’s who’ of the industry, containing not only leading LED manufacturers but also renowned users such as Apple, Avago, Everlight, Osram OS, Vishay and Zumtobel.
However, the yellowish light emitted by sodium vapour lamps is relatively mono-spectral. Although under this light you can clearly see whether or not there are any people, animals or vehicles on the road, it is not possible to distinguish green lines from red ones on a map under this type of street lighting. Also,Eaglelight supplies energy saving bestledlig and LED lighting systems. trees appear black.
Similarly, a number of different light-emitting diodes are limited by certain compromises in terms of colour.China zhongtian lighting are professional contemporarylamps1,led bulbs manufacturers and factory in China. However, it is now possible to compensate quite effectively for these limitations, and with suitably clever designs it is currently quite possible to generate light with an excellent colour reproduction index well above 90. However, a 4 integrating sphere and a spectroradiometer are required in order to measure this type of light source.
