Light irradiating unit, lighting unit and method for manufacturing lighting unit

摘要

A light irradiating unit is provided which is easy to manufacture with a large light production that is stable in luminous intensity and superior in life duration. The light irradiating unit comprises an illuminant loading member that has a curved illuminant loading face on which a plurality of illuminants are loaded, a holding frame that holds the illuminant loading member and a tabular heat-dissipating member that has predetermined elasticity and/or flexibility. The heat-dissipating member is attached to a back face of the illuminant loading member and a supporting face of the holding frame that faces to the back face of the illuminant loading face respectively by making use of its elasticity and/or flexibility.
