Definitions

  • the present invention relates to a fog lamp, or the like, for vehicle lighting systems. More specifically, the present invention relates to a fog lamp, or the like, which employs semiconductor light sources.
  • Light emitting semiconductors such as high output light emitting diodes (LEDs)
  • LEDs can now produce white light at sufficient levels so that semiconductor light sources can be used instead of incandescent or gas discharge lamps to create lighting systems such as vehicular headlamps and signaling lamps.
  • semiconductor light sources present the lighting system designer with some unique challenges.
  • the light output of even high output semiconductor light sources is still much less than conventional incandescent and gas discharge lamps.
  • conventional lighting system designs, intended for such prior art light sources with much higher light output levels are generally too inefficient at making use of the light emitted from semiconductor light sources.
  • operating high output semiconductor light sources require effective cooling of their semiconductor junctions to prevent failure of the light source, and the provision of such cooling in a vehicular environment can be challenging.
  • a vehicular lighting fixture for producing light in a desired pattern.
  • the fixture includes a substrate, at least one set of a semiconductor light source, and an optical body.
  • Each semiconductor light source has a light emitting surface and is mounted to the substrate while also being in thermal connection with the substrate.
  • the optical body includes a light receiving surface and a light output surface.
  • the optical body is mounted to the substrate such that the light receiving surface is located immediately adjacent the light emitting surface of the semiconductor light source. Additionally, the optical body is mounted to the substrate such that the light output surface is located to produce a desired output light pattern from the fixture.
  • the present invention also includes a base member for mounting the fixture to a vehicle, with the substrate being affixed to the base member and in thermal connection with the base member. There is also set of cooling fins in thermal connection with the base member to remove waste heat from the base member.
  • An electrical circuit board including power regulation circuitry is connected to a set of electrical connectors extending out of the fixture. The electrical circuit board is operable to provide a suitable power supply from the electrical connectors to each of the at least one semiconductor light sources.
  • the present invention also has a lens allowing light output from the light output surface of the optical body to exit the fixture. The lens engages the base member to form a weather proof enclosure with the base member, the enclosure enclosing the substrate, the at least one semiconductor light source and optical body, and the electrical circuit board.
  • the present invention provides a novel vehicular light fixture.
  • the light fixture is compact, yet efficient, and employs semiconductor light sources to produce output light in desired patterns.
  • the fixture can be used to produce fog lamps, driving lamps and other non-headlamp vehicle lighting functions.
  • one or more semiconductor light sources and a corresponding number of optical bodies are employed in the fixture to produce the desired light pattern.
  • FIG. 1 shows an exploded perspective view of the back and side of a light fixture in accordance with the present invention.
  • FIG. 2 shows an exploded perspective view of the front and side of the fixture of FIG. 1 .
  • a vehicular lighting fixture in accordance with the present invention is indicated generally at 10 in FIGS. 1 and 2 .
  • lighting fixture 10 is a fog lamp which can be optionally activated by a driver in conditions of fog, mist, dust or the like to provide additional low level illumination of a road surface.
  • the present invention is not limited to use with fog lamps and can instead be employed in a wide range of vehicular lighting system fixtures, including driving lights, daytime running lights or other vehicular fixtures producing desired illumination patterns.
  • Fixture 10 has a base member 12 and a lens 14 which form a waterproof enclosure for the electronic components, described below, and other components of fixture 10 .
  • the base member 12 includes a heat sink, generally shown at 16 , which includes a series of cooling fins 18 which are used to remove waste heat from the interior of fixture 10 as described below.
  • the base member 12 is fabricated from die cast aluminum or zinc alloys, and cooling fins 18 are integrally formed as part of base member 12 .
  • the present invention is not so limited and it is contemplated that the base member 12 may include a portion, or portions, formed of a suitable plastic material joined with a separately formed set of cooling fins 18 which can be thermally connected to the interior of the fixture 10 .
  • the lens 14 is formed of any suitable material such as polycarbonate or acrylic and can be transparent or colored, as desired. As shown in the Figures, the lens 14 includes a peripheral lip 20 which is received in, and affixed to with a suitable adhesive, a complementary channel 22 (best seen in FIG. 2 ) in base member 12 to form the enclosure of the fixture 10 .
  • three semiconductor light sources 24 are employed to produce the desired light.
  • the present invention is not limited to using three semiconductor light sources 24 and fewer or more semiconductor light sources can be employed as required to form the desired light pattern produced by fixture 10 .
  • fixture 10 can only employ a single semiconductor light source 24 .
  • fixture 10 is to be employed as a driving lamp, or if lens 14 is tinted, four or more semiconductor light sources 24 can be employed.
  • the semiconductor light sources 24 are thermally connected to a thermal substrate 26 which may be any suitable substrate that can transfer heat away from semiconductor light sources 24 when they are operating.
  • the substrate 26 includes a layer of fiberglass reinforced plastic atop a layer of copper. The layer of fiberglass reinforced plastic is removed from substrate 26 where the semiconductor light sources 24 are mounted, such that the semiconductor light sources 24 are mounted in thermal connection to the exposed layer of cooper. In this manner, waste heat produced in semiconductor light sources 24 is readily transferred to the copper layer of the substrate 26 .
  • An electrical circuit board 28 is mounted to the substrate 26 adjacent to the semiconductor light sources 24 .
  • the circuit board 28 includes suitable power supply control circuitry to regulate and supply power to the semiconductor light sources 24 , which are electrically connected to the circuit board 28 .
  • the power supply control circuitry employed is not particularly limited and any suitable circuitry, as will occur to those of skill in the art, can be employed.
  • the circuit board 28 further includes a set of electrical power input connectors 30 , which receive electrical power from the vehicle in which fixture 10 is installed; that electrical power is regulated and supplied to the semiconductor light sources 24 by the circuitry on the circuit board 28 .
  • each semiconductor light source 24 is paired with a respective optical body 32 , which gathers the light emitted from the corresponding semiconductor light source 24 and outputs that light as a portion of the desired light pattern.
  • the illustrated embodiment employs three semiconductor light sources 24 , and thus employs three optical bodies 32
  • the present invention is not so limited and more or fewer semiconductor light sources 24 can be employed with a corresponding number of optical bodies 32 .
  • the specific implementation of the optical body 32 is similar to that described in PCT Application Serial No. CA 08/000,139, claiming priority from U.S. Provisional Patent Application 60/897,352 filed Jan. 25, 2007 and assigned to the assignee of the present invention.
  • the contents of these previous applications are incorporated herein, in their entirety, by reference. While it is presently preferred that the optical body 32 correspond to the design disclosed in the 60/897,352 application, the present invention is not so limited and any other suitable means for efficiently gathering and directing the light from the semiconductor light sources 24 can be employed as will occur to those of skill in the art.
  • Each optical body 32 has a general “D”-shape and includes a pair of mounting legs 34 which are used to mount the optical body 32 to the substrate 26 .
  • Each optical body 32 is mounted to the substrate 26 such that that the light receiving surface 68 of each optical body 32 is located immediately adjacent to the upper (light emitting) surface 38 of the semiconductor light source 24 such that substantially all of the light emitted from each semiconductor light source 24 enters each respective optical body 32 .
  • the light which enters the optical body 32 then travels through the optical body 32 by total internal reflection until it exits the light output surface 40 of the optical body 32 .
  • the appropriate geometry for the light output surface 40 i.e. —curvature, thickness, the flat spots, etc.
  • any desired thickness or cross section shape changes along the optical body 32 as described in the above-mentioned PCT Application Serial No. CA 08/000,139, basing priority on U.S. Provisional Patent Application 60/897,352
  • the resulting light pattern produced by fixture 10 can be created as desired.
  • a retaining member 42 which may be formed of a suitable plastic material or metal, is fastened to the substrate 26 (surrounding the optical bodies 32 ) and to the base member 12 such that the copper layer of the substrate 26 is in thermal contact with the base member 12 , and the substrate 26 and optical bodies 32 are maintained in a predefined position within the enclosure of the fixture 10 .
  • the electrical power input connectors 30 extend through an elastomeric sealing member 44 to a wiring harness connector receptacle 46 formed in the base member 12 .
  • the receptacle 46 can receive a wiring harness connector to provide electrical power to the circuit board 28 via electrical power input connectors 30 .
  • the fixture 10 preferably further includes at least one adjustment mechanism 48 which interfaces with base member 12 to allow the mounting position of fixture 10 in a vehicle to be altered to aim the output light pattern from fixture 10 as desired.
  • Fixture 10 provides a number of advantages in that it provides for appropriate cooling of semiconductor light sources 24 without incurring undue manufacturing costs.
  • the use of the optical bodies 32 provides for the efficient utilization of the light emitted by the semiconductor light sources 24 and the formation of desired light patterns output by the fixture 10 , all with a relatively overall size and volume required for fixture 10 .
  • fixture 10 can be manufactured in a sufficiently small volume that it can be retrofitted to existing vehicles to replace existing incandescent fixtures.
  • the present invention provides a compact yet efficient light fixture employing semiconductor light sources to produce output light in desired patterns.
  • the fixture can be used to produce fog lamps, driving lamps and other non-headlamp vehicle lighting functions.
