Geometrical properties

Incremental concentration factor (fig. 6) Ci = f (i): N+^R, i є (1; n) is a series of functions converging to n ^ да for ©A = const. At ©A = 5°, the biggest contribution to concentration will have the second zone, the for higher zones the contribution falls down exponentially. It can be seen from graphs that CLON with n > 10 has no real sense. For higher acceptance angles the number of zones with meaningful contribution to the overall concentration will be even less, e. g. for ©A = 20° CLON should have not more than 6 zones.

Yet more interesting is to read the dependance of cummulative (or total) concentration factor (fig. 7) Ci = f (i). It can be seen that CLON’s maximal concentration factor for ©A = 5° is C = 5. No CLON of practical measure will have acceptance angle lower.

Conclusions

From mentioned above follows that CLON is expected to be much advantageous in comparison to the classical solution of CPC, which is assumed to be a practical realisation of so called ideal concentrator. But on the other hand it is necessary to note that CLON is advancing CPC only at level of practical realisation and usage of flat mirrors is possible only due to flat character of output area. Rays incoming at angle of incidence equal to ©A will be concentrated nearby foci and there will be then higher local irradiation than on the rest of receiver, what can never be reached by CLON. However, this is neither supposed to CLON nor CPC.

Further it is necessary to remark that CLON is not intended to be and is not an approximation of common CPC, so also not its modification. Its concept given by optical scheme is new and principially different from CPC.
