PROBLEM TO BE SOLVED: To improve the light emitting efficiency of an LED lamp by reflecting light emitted from an LED light emitting element in a direction right above. SOLUTION: This LED lamp 10 is provided with a first lead 3 where a reflection plate 4 is formed and a second lead 6. The reflection plate 4 is provided with a reflection parabola 5 and the bottom surface of the reflection parabola 5 is turned to a concave shape. Low melting point glass 2 is incorporated in the reflection parabola 5 and the LED light emitting element 1 is bonded to the flat surface of the low melting point glass 2. The light 7 emitted from the LED light emitting element 1 is transmitted through the low melting point glass 2 and reaches the bottom surface of the reflection parabola 5. Since the bottom surface of the reflection parabola 5 is the concave shape, the light 7 is reflected in the direction right above, efficiently transmitted through epoxy resin 11 in one direction and emitted in the air. |
