Abstract:
A wavelength converting element (1) comprises: a support member (2) having a support surface (2a); and a wavelength converting member (40) that is disposed above the support surface (2a). The wavelength converting member (40) has a radiating surface (6) that is located on the opposite side from the support surface (2a). The radiating surface (6) includes a peripheral region (6a) that includes the periphery of the radiating surface (6) and a central region (6b) that is surrounded by the peripheral region (6a). At least part of the peripheral region (6a) has a first apex (P1) that protrudes from the central region (6b) in a direction away from the support surface (2a).
