PROBLEM TO BE SOLVED: To solve the problem that luminous efficiency is lowered due to insufficient diffusion of heat from a fluorescent material in a conventional LED light-emitting device.SOLUTION: An LED light-emitting device comprises an LED element mounted on a substrate, a support member formed on the substrate so as to surround the LED element, a wavelength conversion member disposed on the support member, and an air layer between the wavelength conversion member and the LED element. The wavelength conversion member is constituted by holding a solvent between a translucent member and a phosphor layer. |
