Key words Galaxies: luminosity function, mass function

We present a composite K-band luminosity function for 10 clusters at low redshift, where member galaxies are identified from an existing spectroscopic survey (the 2dF galaxy redshift survey). Our kinematically selected K-band luminosity function is well fitted by a Schechter function with M * K = ?24.50 + 5 log h and ? = ?0.98 over ?27 << MK ? 5 log h < ?22. This is very similar to the 2dF field value and suggests that the integrated mass accretion history of galaxies does not vary strongly with environment
