Abstract: A wavelength conversion member of the present disclosure includes a first matrix, phosphor particles embedded in the first matrix, and at least one selected from the group consisting of first filler particles embedded in the first matrix and surface coating layers respectively covering surfaces of the phosphor particles. The wavelength conversion member satisfies at least one relationship selected from the group consisting of |n3−n1|>|n1−n2| and |n4−n1|>|n1−n2| wherein n1 is a refractive index of the first matrix, n2 is a refractive index of the phosphor particles, n3 is a refractive index of the first filler particles, and n4 is a refractive index of the surface coating layers.

Abstract: A heat transfer device includes a first member and a first and second heat transfer element. In the first heat transfer element, a first contact area that is a contact area between the first heat transfer element and the first member varies. In the second heat transfer element, a second contact area that is a contact area between the second heat transfer element and the first member varies. The first contact area is greater when magnitude of a first external force applied to the first member is smaller than a first threshold than when the magnitude of the first external force is equal to or greater than the first threshold. The second contact area is smaller when the magnitude of the first external force is smaller than the first threshold than when the magnitude of the first external force is equal to or greater than the first threshold.
