CONSTITUTION: A lens main body unit is configured to be attachable to an LED. A connection groove is formed on the lower side of the lens main body unit for the LED to be arranged by being pressed in. A total reflection unit (20) is formed on the upper part of the lens main body unit for the light of the LED to be totally reflected. A light emitting unit (30) is formed on the side of the lens main body unit for the light of the LED to be emitted.
