  • Patent number: 9151461
    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.

  • Patent number: 9068712
    Abstract: A vehicular light-emitting diode lamp includes a housing having a compartment receiving a reflective member including first and reflective surfaces and a partitioning section between the first and second reflective surface. The partitioning section includes two lateral portions respectively engaged with two mounting portions of the housing. A lamp seat is mounted in front of the partitioning section of the reflective member. First and second LED modules are mounted to the lamp seat and are electrically connected to a circuit board unit. The first LED module emits light beams towards a rear and a side of the first reflective surface. The second LED module emits light beams towards a rear and a side of the second reflective surface. Light beams emitted by the first and second LED modules transmit are reflected by the first and second reflective surfaces and then transmit cover in front of the reflective member.

  • Patent number: 7267451
    Abstract: A backlight module without a light guiding plate and a diffusing plate is disclosed, in which a reflective layer having a light scattering structure is first disposed on a backplate and then at least a reflective mirror is provided on the reflective layer of the backplate. Further, a transparent plate is disposed on the at least reflective mirror. The backplate, the at least a reflective mirror, the reflective layer and the transparent plate form an enclosed space and thus the backlight module without a light guiding plate and a diffusing plate is completed. In another form of the backlight module without a light guiding plate and a diffusing plate, the light scattered structure is formed directly on the backplate. When a light-emitting unit emits a light source, the light source is uniformly given off through the light scattering structure, promoting use efficiency of the light source.
