Claim:
1. A vehicular lamp device comprising: a lamp seat including a back board, with the lamp seat including a compartment delimited by the back board; a lighting device mounted in the compartment of the lamp seat, with the lighting device including a circuit board, and with a plurality of lighting elements mounted on the circuit board; a reflective seat mounted in the compartment of the lamp seat, with the reflective seat including a reflective board having a reflective face on a front side thereof, with the lighting device located between the back board of the lamp seat and the reflective seat along a longitudinal axis, and with each of the plurality of lighting elements spaced from the longitudinal axis in a radial direction perpendicular to the longitudinal axis; a lens seat mounted in the compartment of the lamp seat, with the lens seat including a plurality of lens portions located in front of the plurality of lighting elements, with the lens seat further including a hollow portion aligned with the reflective board of the reflective seat, with each of the plurality of lens portions including a light input portion on a rear side thereof, with each of the plurality of lens portions further including a light guiding portion in front of the light input portion and a first light output face in front of the light guiding portion and parallel to the light input portion, and with a refractive portion extending from a front end of each light guiding portion towards the longitudinal axis; and a front cover mounted outside of the lens seat, with the front cover including a light transmitting portion aligned with the first light output portions of the lens seat, with the front cover further including a half reflective portion aligned with the reflective face, and with the half reflective portion including a partially transparent front surface and a partially reflective rear surface, wherein a portion of light rays emitted from each of the plurality of lighting elements entering the light guiding portion of a corresponding one of the plurality of lens portions transmits through the first light output face of the corresponding one of the plurality of lens portions and the light transmitting portion of the front cover and is projected forwards to form a transmitted lighting pattern area, and wherein another portion of the light rays entering each light guiding portion is projected onto the reflective face of the reflective seat after refraction by the refractive portion, is reflected to the partially reflective rear surface of the half reflective portion of the front cover, and is then reflected back and forth between the reflective face of the reflective seat and the partially reflective rear surface of the half reflective portion of the front cover, forming a layered lighting pattern area towards the longitudinal axis.
