Abstract (en)

[origin: EP3088794A1] The purpose of the present invention is to provide an LED lamp comprising a novel cooling/radiation means. This LED lamp comprises: a plurality of LED elements; a plurality of light-source supporting bodies having each of the plurality of LED elements mounted thereon and extending along the lamp axial line; and a hermetically sealed glass container encasing the light-source supporting bodies. The plurality of light-source supporting bodies are arranged so as to form an n-angle shape (n = a natural number such as 3, 4, ....), as viewed from a cross-section perpendicular to the lamp axial line, such that a gas flow path is formed that flows along the lamp axial line between both end sections thereof. The light-source supporting bodies have a ventilation structure that penetrates between an LED element mounting surface and a rear surface, such that an inflow and outflow of gas in the gas flow path is formed.
