Abstract
A lens for a vehicular lamp includes an outer annular portion and a central portion. The outer annular portion surrounds a central axis and includes an incident face on a rear thereof. The outer annular portion further includes a light guiding portion in front of the incident face. The light guiding portion includes a reflective face on an outer side thereof. The central portion is surrounded by the outer annular portion and is connected to the light guiding portion. The central portion includes front and rear faces. The front face includes an outer edge connected to the reflective face. The rear face includes a plurality of grooves. A portion of light rays from a light source entering the light guiding portion via the incident face transmits out of the lens via the reflective face. Another portion of the light rays is reflected to the central portion and reaches the grooves.
