Patent ID: 8704261

Claim:
A light emitting module comprising: a semiconductor light emitting element; a plate-shaped light wavelength conversion member that is provided so as to face a light emitting surface of the semiconductor light emitting element and is configured to convert a wavelength of a light emitted by the semiconductor light emitting element; a filter layer that is formed, of surfaces of the plate-shaped light wavelength conversion member, on at least one of the surfaces facing the semiconductor light emitting element and a side surface and is configured to transmit the emitted light emitted from the semiconductor light emitting element and to reflect light whose wavelength has been converted by the light wavelength conversion member; and an adhesive layer that adheres the filter layer and the semiconductor light emitting element, wherein the semiconductor light emitting element is formed such that a ratio of energy of the emitted light from the semiconductor light emitting element that is within a range of ±60° with respect to the front direction to a total energy of the emitted light is 80% or more, the filter layer is formed of the surfaces of the light wavelength conversion member, on the at least one of the surfaces that faces the semiconductor light emitting element, and the filter layer is formed such that a transmittance, occurring when the emitted light emitted by the semiconductor light emitting element is incident on the filter layer at an incident angle of 60° , is 80% or more, and the adhesive layer contains a material having a refractive index of 1.3 or more selected from the group consisting of: a fluorine adhesive, dimethyl silicone, bisphenol A epoxy, and TiO 2 sol-gel agent.
