4 Claims.
This invention relates generally to lamps for motor vehicles and refers more particularly to that type designed for use as headlights.
In the past it has been customary to form such lamps with an outer casing of the desired configuration and to mount within this casing as a subassembly the essential elements of the lamp such as the reflector, bulb socket and the electrical terminals or connections. However, the development of lamps has progressedto such a point that it is now desirable to use a filament instead of a bulb as the lighting element and to mount within the lamp casing as a hermetically-sealed lighting unit 'a reflector, filament, lens and electrical terminals or connections. Thus, it has been necessary to redesign the mountings for such elements.
In View of the foregoing, it is an object of the present invention to provide the hermeticallysealed units with mountings that permit the units to be readily adjusted so that the beams of light projected therefrom may be properly directed.
Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:
Figure l is a longitudinal vertical sectional view through a lamp structure embodying our invention;
Figure 2 is a vertical sectional view taken substantially on the line 22 of Figure 1;
Figure 3 is a detail view of the outer ring;
Figure 4 is a detail view of the inner ring.
Referring now to the drawing, A is the lamp casing, B is the hermetically-sealed unit, and C is the mounting embodying our invention for said unit.
In the present instance, the casing A may be any desired configuration and may be mounted in any suitable manner upon a motor vehicle. Preferably the casing A is elongated in form and is provided at its forward end with an opening I in which the unit B is mounted.
The hermetically-sealed lighting unit B may be made in any suitable manner and preferably has a shell of heat insulating glass, known in the trade as Pyrex, provided with meeting front and rear walls 2 and 3 and an annular bead 4 at the juncture of said walls. The front wall 2 of this shell comprises the lens, while the front face of the rear wall3 has a coating of suitable material such as aluminum forming a reflector 5. A suitable filament E is carried by the rear wall 3 at the center thereof and is provided with suitable electrical terminals l for connection with electric conductors (not shown).
The mounting for the unit B preferably comprises a pair of cooperating rings 8 and ii, re spectiveiy, spring clips It, and an adjusting screw El. As shown, the rings 8 and S are arranged one inside the other in substantially concentric relation, the point l2 being the common center. Preferably the outer ring 8 has an outwardly offset annular flange l3 and is split to permit its insertion in contracted form into the opening l. Intermediate its front and rear edges, this flange I3 has an outwardly opening circumferentially extending channel ii that receives the edges of an inturned annular flange l5 of the casing. Any suitable tool (not shown) be used to expand the flange !3 of the ring into firm engagement with the flange l5 of the casing. A bezel i5 is sleeved on an annular portion ll of the flange and is provided with an opening 58 for the lighting unit B. The inner ring 9 is provided at its rear edge with an inturned flange l9 and is provided at its forward edge with an offset annular flange 2G substantially L-shape in cross section forming a seat for the bead 4 of the lighting unit. The spring clips iii are U-shaped in configuration and straddie this flange. 2i! and bead 4 at spaced points circumferentially thereof to retain the parts in assembled relation. Any suitable means such as the spring 2i riveted to the inturned flange W of the inner ring and having an open, returnbent portion 22 engaging the rear edge of the outer ring 8 may be employed for preventing the inner ring and lighting unit carried thereby from falling out after they have been inserted in the casing. The adjusting screw ll extends freely through an enlarged elongated opening 23 in the outer ring 8 and threadedly engages a nut 24 swedged or otherwise suitably secured to a flattened portion 25 of the inner ring. An elongated strip 36 carried by the screw l i bridges the opening 23 and slidably engages the outer side of the outer ring 8. If desired, a washer 3? may be sleeved upon the screw ll between an enlargement 38 thereof and said strip free end 39 of the screw is polygonal and extends through an elongated opening 4%) in the casing A so that it may be engaged outside the casing by a suitable tool (not shown) when it is desired to make an adjustment. Thus, with this construction the lighting unit B may be adjusted relative to the casing A to vary the direction of the beam of light projected from the unit by first loosening the screw it in the nut 24 and then shifting the screw, as indicated by dotted lines in Figure 1, to cause the inner ring 9 and unit B to be moved in unison as desired. The screw H may then be tightened in the nut 24 to hold the parts in adjusted position.
What we claim as our invention is:
1. A lamp having a casing provided with an opening, a light unit Within said casing for pro jecting light rays through said opening, and a mounting for said unit including a pair of substantially concentric rings within said casing, one of said rings being connected to the casing and having an elongated opening therein, the second of said rings forming a seat for and being connected to said unit, a nut fixed to the second ring, and an adjusting screw movable freely in the elongated opening and threadedly engaging said nut, said screw extending freely through another opening in said casing and being accessible and operable from the outside of said casing.

3. A lamp having a casing provided with an opening, a light unit within said casing for projecting light rays through said opening, and a mounting for said unit including a pair of substantially concentric rings within and formed separate from said casing, one of said rings forming a seat for the second ring and having an annular flange extending outwardly through said opening, the first mentioned ring being connected to said casing, the second mentioned ring forming a seat for and being connected to said unit, means accessible outside the casing for adjusting the second mentioned ring and unit relative to the first mentioned ring, the second mentioned ring having an inturned flange, and means for holding the second mentioned ring and unit against outward displacement relative to said casing including a leaf spring fixed to said inturned flange and having an open return-bent portion engaging the rear edge of the first mentioned ring.
4. A lamp having a casing provided with an opening, a light unit within the casing for projecting light rays through said opening, and a mounting for said unit including a pair of substantially concentric rings within said casing, one of said rings forming a seat for the second mentioned ring and being connected to the casing, the second of said rings forming a seat for and being connected to said unit, the first mentioned ring and said casing having substantially aligned openings therein, a nut fixed to the second mentioned ring, and an adjusting screw movable freely in said aligned openings and threadedly engaging said nut, said screw being accessible and operable from the outside of said casing.
