Integrating sphere detector Led Testing System.
Wonled light applicating interating sphere detector testing system for the ceiling lights, table lights, floor lights, wall lamps, pendants and sport light.
principle of integrating sphere detector
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. The effects of the original direction of light are minimized. An integrating sphere may be thought of as a diffuser which preserves power but destroys spatial information. It is typically used with some light source and a detector for optical power measurement. A similar device is the focusing or Coblentz sphere, which differs in that it has a mirror-like (specular) inner surface rather than a diffuse inner surface.
Integrating Sphere Fundamentals and Applications
An integrating sphere collects electromagnetic radiation from a source completely external to the optical device, usually for flux measurement or optical attenuation. Radiation introduced into an integrating sphere strikes the reflective walls and undergoes multiple diffuse reflections. After numerous reflections, the radiation is dispersed highly uniformly at the sphere walls. The resulting integrated radiation level is directly proportional to the initial radiation level and may be measured easily using a detector.
That Wonled light be always support you with high quality of LED lights, and was established in 1995 for lighting metal parts. Like aluminum, Zinc alloy die-casting, metal tubes etc. And improve to be complete set of lights in 2008. wonledlight had rich lighting parts and complete R&D manufacturing experienced.
