PROBLEM TO BE SOLVED: To provide an LED signal lamp eliminating loss of light quantity to guided light.SOLUTION: An LED signal lamp 1 comprises an LED 3 to be a light source, and a lens 4 including a plurality of light guide bodies 5 arrayed in a direction orthogonal to an optical axis X of the LED 3. In the LED signal lamp, cutting 6 for collecting light emitted from the LED 3 on a light emission surface 5b of each light guide body 5 of the lens 4 is executed on a light incident surface 5a of each light guide body 5, or cutting for light distribution control (for example, a combination of fish-eye cutting, prism cutting and flute cutting) is executed on the light emission surface 5b of each light guide body 5 of the lens 4. |
