摘要:
An LED lighting device of embodiment comprising an LED light source which generates an ultraviolet light or a visible light, an axisymmetric transparent member which is provided over the light source and which is transparent to visible light, and an axisymmetric light scattering member disposed in the transparent member apart from the light source. A distance of closest approach L2 between the light source and the light scattering member, and an area C of a light emitting surface of the light source satisfy the settled relation. A length L1 of the light scattering member, and an absorption coefficient μ (1/mm) of the light scattering member satisfy the settled relation. A diameter d1 of the bottom surface of the light scattering member, the distance of closest approach L2, and a refractive index n of the transparent member satisfy the settled relation.
