Definitions

  • This invention relates to new and useful improvements in an non-glare headlight bulb for automobiles.
  • the invention proposes to characterize the headlight bulb by the fact that it comprises a standard automobile headlight bulb having a glass bulb, and a plurality of opaque dots on the bulb material to make it non-glare.
  • the invention proposes to form the dots by painted or printed or other material preferably engaged on the outer surface of the bulb.
  • the invention contemplates several modified forms in which the dots are arranged at different areas on the glass bulb.
  • the invention contemplates a modified form in which a glass shell made of sections is mounted on the glass bulb and is provided with opaque dots alignable with the opaque dotsof the glass bulb and adapted to be adjusted to various positions in partial aligmnent or completely out of alignment, as desired, to vary the non-glare effect.
  • Fig. 1 is a side elevational view of a reflector and bulb constructed in accordance with this invention.
  • Fig. 2 is a front elevational view of the bulb, per se.
  • Fig. 3 is a fragmentary enlarged sectional view taken on the line 33 of Fig. 2.
  • Fig. 4 is a fragmentary side elevational view similar to a portion of Fig. 1 but illustrating a modified construction.
  • Fig. 5 is another fragmentary side elevational View similar to Fig. 1 but illustrating a still further modified form.
  • Fig. 6 is another fragmentary side elevational view similar to a portion of Fig. 1 but illustrating another modification.
  • Fig. 7 is a fragmentary sectional view taken on the line 'l-I of Fig. 6.
  • Fig. 8 is a fragmentary sectional view of a nonglare bulb constructed in accordance with this invention and shown applied to a reflector.
  • the non-glare headlight bulb for automobiles comprises a standard automobile headlight bulb l having a .glass :bulb rillv and a socket portion l (W.
  • The. bulb is intended to engage within theusual socket II of an automobile headlight having areflector l2.
  • far the device is conventional.
  • the device is conventional.
  • the glassbulb 10 is provided with a plurality of opaque dots l4.
  • the dots are approximately oneeighth of aninchin diameter. :Sixteen to twenty of them arearranged in. a square inch of area. These dots I4 may belpainted, printed .or in any othermannerformed on .thematerialof the glass bulb.
  • the dots 1:4 are arranged on-the front portion of the bulb l0.
  • .In.Fig..4 a modified form of the invention has been disclosed which is substantially identical to the. prioriform, distinguishing merely in the, fact :that opaque :dots ,l 4' .are .arrangedupon the sides of the bulb. These opaque dots cut down the glare of the reflected rays of the bulb.
  • Fig. 5 another form of the invention has been disclosed in which the bulb is provided with opaque dots I4 on its front face and opaque dots I4 on its side.
  • This bulb may be advantageously employed as a headlight for vehicles since it cuts down both the glaring direct, and the glaring indirect rays of the lamp.
  • Figs 6 and 7 another form of the invention has been disclosed which distinguishes from the prior form in the fact that an arrangement has been provided whereby it is possible to control the degree of glare of the headlight. It should be understood that as the glaring rays are cut down the light of the bulb is also cut down. For this reason it may be desirable to permit more or less of the glaring rays to pass.
  • This shell I5 is made from two half sections I5 and I I5 Each of these sections is mounted in a substantially U-shaped half ring member I6 and "5 respectively. These half ring members together encircle the base portion of the bulb. Fastening elements I! engage through adjacent end portions of the substantially U-shaped half ring members l6 and I6 to releasably connect them together.
  • the shell 15 is provided with a plurality of opaque dots [8 arranged to normally align with the dots l4 and Hi. When desired the fastening elements I! may be loosened, to
  • this form of the invention is similar to the pre vious form.
  • the non-glare headlight comprises a standard automobile headlight bulb having a glass bulb l0 provided with a plurality of pimples or projections 10 upon its outer surface. preferablyone-eighth of aninch in'diameter and arranged approximately 16 to 20 per square inch. The outer surfaces of these projections lll are covered with opaque material 20.
  • These projections are of opaque closely spaced non-reflecting dots arranged circumferentially on said glass bulb, a glass shell completely encasing said glass bulb, a plurality of opaque closely spaced non-reflecting dots arranged circumferentially on said glass shell and in aligned positions with the dots of said bulb, and means for rotatively supporting said shell on said bulb, whereby vv said shell may be turned relative to-said bulb to move said aligned dots out of alignment, said shell being formed from two half shell sections engaging said glass bulb, said means, comprising a half ring substantially U-shaped member rigidly mounted on the base of each of said shell sections and engaging around said glass bulb at its base, and means for releasibly connecting together the [adjacent ends of said half ring substantially U- preferably is black paint having heavy, pigments.
  • the opaque dots may be of any desired size and may be formed in the" glass during the manufacture of the bulb.
