COB Lenses for light diffuser

Using the COB Led with relative holder, the angle distribution is around +/- 80 degrees. The customer needs to drive the light to create diffuser light for special applications.

IODA has developed a new led lens which can increase the light angle emitted from a COB (usually +/- 70°) reaching a value higher than +/- 100°.
After many tests in the field, we have identified the C6 model as the best solution to diffuse the light from a COB source.

In the two pictures herebelow we have used a COB Citizen. You can compare the picture on the left side, where C.O.B. is without any lens, with the picture on the right, where the C6-B lens has been fitted: you can easily notice how the angular opening of the angle of the emitted light is much wider, lighting up in part also the support surface of the heat sink.

After different laboratory tests, we have indentified in our model C6 (both in A and B version) and more recently in the latest C7 model the best solution to diffuse light from a COB souce.

The difference between C6-A and C6-B models is the surface roughness of the upper part of the lens: in fact in the C6-B model the surface roughness is bigger and the reflected light is more intense.


The new model called C7  is also suitable for COB high power and with emission diameters up to 20mm.
