Recent observations of the light component of the cosmic-ray spectrum haverevealed unexpected features that motivate further and more precisemeasurements up to the highest energies. The Dark Matter Particle Explorer(DAMPE) is a satellite-based cosmic-ray experiment that is operational sinceDecember 2015, continuously collecting data on high-energy cosmic particleswith very good statistics, energy resolution, and particle identificationcapabilities. In this work, the latest measurements of the energy spectrum ofproton+helium in the energy range from 46 GeV to 316 TeV are presented. Amongthe most distinctive features of the spectrum, a spectral hardening at$\sim$600 GeV has been observed, along with a softening at $\sim$29 TeVmeasured with a 6.6$\sigma$ significance. Moreover, by measuring the energyspectrum up to 316 TeV, a strong link is established between space- andground-based experiments, also suggesting the presence of a second hardening at$\sim$150 TeV.
