Lightning protection for a wind turbine blade

Wind turbine blade (10) extending along a longitudinal axis from a root end (17) to a tip end (15), the wind turbine blade comprising a first blade section (44) extending along the longitudinal axis to a first end (50), and a second blade section (46) connected to the first blade section, the second blade section extending along the longitudinal axis from a second end (52) towards the tip end (15), the first blade section comprising a first airfoil region (34a), the second blade section comprising a second airfoil region (34b), the wind turbine blade comprising a first down conductor (80) for conducting lightning current to ground, the blade further comprising one or more lightning receptors (86a-86e) at or in proximity of an external surface (35a, 35b) of the wind turbine blade, a smallest distance (101) from a first lightning receptor (86a) of the one or more lightning receptors to the first end of the first blade section being less than or equal to a chord length of a chord (38) of the wind turbine blade at the first end, the first lightning receptor being in electrical connection with the first down conductor.
