Definitions

  • the invention relates to a headlamp device for a vehicle capable of emitting low beam and high beam light rays.
  • a conventional headlamp device disclosed in Taiwanese Utility Model Patent No. M248960 includes a headlamp 80 and a headlight function switching device 90.
  • the headlamp 80 includes a light emitting member 81, a reflecting member 82 and a lens 83.
  • the light emitting member 81 generates light beams.
  • the reflecting member 82 and the lens 83 are respectively located at two opposite sides of the light emitting member 81.
  • the headlight function switching device 90 is disposed between the light emitting member 81 and the lens 83, and includes a fixed plate 901, a solenoid valve 902 and a blocking board 903.
  • the solenoid valve 902 is fixedly mounted to the fixed plate 901.
  • the blocking board 903 is operable by the solenoid valve 902 to move relative to the light emitting member 81 in an up-down direction between an upper position and a lower position.
  • the blocking board 903 When the blocking board 903 is at the upper position, the light beams generated by the light emitting member 81 are reflected by the reflecting member 82 and propagate in such a manner that some of the light beams are blocked by the blocking board 903 while the remaining light beams pass through the lens 83 to serve as low beam light rays (see Figure 8 ) which form a light distribution pattern that has a clear cut-off line.
  • the blocking board 903 When the blocking board 903 is at the lower position, the light beams generated by the light emitting member 81 are reflected by the reflecting member 82 and pass through the lens 83 without being blocked by the blocking board 903, so as to serve as high beam light rays (see Figure 7 ).
  • the conventional headlamp device is switchable between a low beam mode where the low beam light rays are generated and a high beam mode where the high beam light rays are generated.
  • the solenoid valve 902 may be slow to react to user input and is prone to malfunction. Once the solenoid valve 902 has malfunctioned, the conventional headlamp device can no longer switch between the low beam mode and the high beam mode.

  • the lower focal point is located at one side of the lower light-incident surface opposite to the lower light-emergent surface.
  • the low-beam reflector is located at one side of the upper focal point opposite to the upper light-incident surface, and has a low-beam reflecting surface that is arc-shaped and that has a first low-beam reflecting focal point and a second low-beam reflecting focal point.

  • the first light source substantially coincides with the first low-beam reflecting focal point of the low-beam reflector.
  • the second light source substantially coincides with the first high-beam reflecting focal point of the high-beam reflector.
  • Each of the first light source and the second light source is operable to switch between an on-state in which light beams are generated, and an off-state in which light beams cease to be generated.
  • the light beams generated by the first light source are reflected by the low-beam reflecting surface of the low-beam reflector such that some of the light beams are blocked by the blocking board while the remaining light beams travel into the upper lens through the upper light-incident surface and exit the upper lens through the upper light-emergent surface to serve as low beam light rays.
  • the light beams generated by the second light source are reflected by the high-beam reflecting surface of the high-beam reflector such that the light beams travel into the lower lens assembly through the lower light-incident surface and exit the lower lens assembly through the lower light-emergent surface to serve as high beam light rays.

  • Each of the first light source 91 and the second light source 92 is operable to switch between an on-state in which light beams are generated, and an off-state in which light beams cease to be generated.
  • Each of the first light source 91 and the second light source 92 is a light-emitting diode made of at least one semiconductor die.
  • the light beams generated by the first light source 91 are reflected by the low-beam reflecting surface 51 of the low-beam reflector 5 such that some of the light beams are blocked by the blocking board 7 (i.e., some of the reflected light beams that do not perfectly pass through the second low-beam reflecting focal point 512 of the low-beam reflecting surface 51 are blocked by the blocking board 7) while the remaining light beams travel into the upper lens 41 through the upper light-incident surface 411 and exit the upper lens 41 through the upper light-emergent surface 412 to serve as low beam light rays.
  • the blocking board 7 blocking some of the light beams, light distribution pattern formed by the low beam light rays has a clear cut-off line as shown in Figure 5 .
  • the light beams generated by the second light source 92 are reflected by the high-beam reflecting surface 61 of the high-beam reflector 6 such that the light beams travel into the lower lens assembly 42 through the lower light-incident surface 422 and exit the lower lens assembly 42 through the lower light-emergent surface 423 to serve as high beam light rays.
  • Light distribution pattern formed by the high beam light rays is shown in Figure 6 .
  • the compound lens unit 4 may provide relatively good stray-light rejection when the low beam light rays are generated. That is to say, when the first light source 91 is in the on-state and when the second light source 92 is in the off-state, the light beams generated by the first light source 91 but traveling in undesirable paths (namely, stray light) may be prevented from exiting the lower lens assembly 42 through the lower light-emergent surface 423. Therefore, stray light will not substantially affect the light distribution pattern formed by the low beam light rays.
  • a distance between the upper light-incident surface 411 of the upper lens 41 and the lower light-incident surface 422 of the lower lens assembly 42 in the direction (X) of the low-beam optical axis (A) ranges from 1 to 30 millimeters.
  • each individual one of the lower lenses 421 of the lower lens assembly 42 constitutes only one of the first section 425 and the second sections 426
  • curvature of each of the first section 425 and the second sections 426 is individually adjustable by adjusting the curvature of the corresponding lower lens(es) 421.
  • the high-beam reflector 6 may prevent the light beams generated by the second light source 92 from dispersing.
  • the lower lens assembly 42 may achieve a better effect of focusing light so that the light beams exiting the lower lens assembly 42 through the lower light-emergent surface 423 may be adjusted to serve as the high beam light rays even when only the second light source 92 is in the on-state (i.e., for the high beam light rays to be generated, it is not necessary for the first light source 91 and the second light source 92 to simultaneously be in the on-state to create overlapping light beams or patterns). Consequently, the embodiment may be relatively energy-saving.
  • the embodiment further includes a heat dissipating member 8 and a fixing frame 3.
  • the heat dissipating member 8 is disposed on the base 2 and serves the purpose of heat dissipation.
  • the fixing frame 3 is disposed in front of the base 2, connects the base 2 to the compound lens unit 4, and has the compound lens unit 4 disposed thereon.
  • the upper lens 41 and the lower lens assembly 42 of the compound lens unit 4 are held fixedly by the fixing frame 3.
  • the embodiment of the headlamp device is capable of emitting low beam light rays and high beam light rays and is switchable between the low-beam mode and the high-beam mode without a solenoid valve. Therefore, the headlamp device according to the disclosure may react relatively quickly when operated and may have a relatively long service life so reliability of the headlamp device is improved. Consequently, the drawbacks of the prior art have been alleviated and the purpose of the invention can certainly be fulfilled.
