The Kepler field is divided into 14 subfields that are adapted to the LAMOST circular field with a diameter of 5{deg}. During the regular survey phase of LAMOST, the LK-project took data from 2012 June to 2017 June and covered all 14 subfields at least twice. In particular, we describe in this paper the second Data Release of the LK-project, including all spectra acquired through 2015-May--2017-June together with the first round observations of the LK-project from 2012 June to 2014 September. The LK-project now counts 227,870 spectra of 156,390 stars, among which we have derived atmospheric parameters (logg, T_eff_, and [Fe/H]) and heliocentric radial velocity for 173,971 spectra of 126,172 stars. These parameters were obtained with the most recent version of the LAMOST Stellar Parameter Pipeline v 2.9.7. Nearly one half, namely 76,283 targets, are observed both by the LAMOST and Kepler telescopes. These spectra, establishing a large spectroscopy library, will be useful for the entire astronomical community, particularly for planetary science and stellar variability on Kepler targets.2018ApJS..238...30Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/238/30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/284 : The USNO-B1.0 Catalog (Monet+ 2003)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)IV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)V/164 : LAMOST DR5 catalogs (Luo+, 2019)V/156 : LAMOST DR7 catalogs (Luo+, 2019)III/284 : APOGEE-2 data from DR16 (Johnsson+, 2020)J/A+A/454/301 : Radial velocities of 6 binaries (Frasca+, 2006)J/A+A/525/A71 : Atmospheric parameters for 1273 stars (Wu+, 2011)J/AJ/141/83 : Kepler Mission.
