发明名称 LIGHT SOURCE
摘要 A light source that restricts the heat accumulation in the phosphor. The light source includes: a substrate 5; LED elements D21, D22, D23, D41, D42 that have been implemented on a main surface of the substrate 5; projections 11 that have been formed in areas of the main surface of the substrate 5 in which any of the LED elements D21, D22, D23, D41, D42 have not been implemented; and a translucent sealing member 7 that has been formed on the substrate in a state that the LED elements D21, D22, D23, D41, D42 and the projections 11 are covered and sealed with the sealing member 7. The sealing member 7 includes a phosphor 13 that converts light from the LED elements D21, D22, D23, D41, D42 into light of a predetermined color. The heat conductivity of the projections 11 is higher than the heat conductivity of the sealing member 7.
