Recent results on direct-photon measurements in Pb-Pb collisions at \fivennfrom central to peripheral collisions, as well as in 0-10% central and 20-40%semicentral Pb-Pb collisions at \sqrt{ s_{NN}}=2.76 TeV with improvedsignificance are presented. A significant direct-photon signal is measured forp_T \gtrapprox 2 GeV/c from central to peripheral Pb-Pb collisions at\sqrt{s_{NN}}=5.02 TeV which is in agreement with model calculations containingpre-equilibrium photons in the intermediate p_T range and prompt photons athigh p_T. No significant direct-photon signal is measured in the low p_Tinterval which is also in agreement with the small thermal-photon signalpredicted by state-of-the art models. On the other hand, a direct-photon signalis measured for p_T > 1 GeV/c with a significance of 3.1 ($1.0 < p_{\rm T} <1.8$ GeV/c) and 3.4 (1.0 < p_T < 2.3 GeV/c) in 0-10% and 20-40% central Pb-Pbcollisions at \sqrt{s_{NN}}=2.76 TeV, respectively. The inverse slopeparameters of non-prompt photon spectra in the low p_T range, 1.1 < p_T < 2.1GeV/c, are T_ eff = 343 \pm 32 (stat)\pm 68(sys) MeV and T_eff = 339 \pm 32(stat)\pm 68(sys) MeV for central and semicentral collisions. In theintermediate p_T} range, 2.1 < p_T < 4.0 GeV/c, the effective temperatures areT_{eff} = 406 \pm 19 (stat)\pm 36(sys) MeV and T_eff = 458 \pm 25 (stat)\pm40(sys) MeV, respectively. The effective temperatures T_eff in the intermediatep_T range are systematically larger compared to those obtained at low p_T(although consistent within uncertainties) which may indicate an earlier photonemission, and thus sensitivity to pre-equilibrium photon production. Directphotons at both energies are in agreement with state-of-the-art theorycalculations over the complete p_T range and measured centralities.
