DETAILED DESCRIPTION OF THE INVENTION

(17) Referring to FIGS. 1, 5, and 9, a lamp 10 is shown having a round shaped housing 12 with a base 13, an outer periphery provided by sides 14, and a front surface 16 providing lens or lens elements 17 through which light is projected from the lamp. The assembly of the lamp is shown in more detail in FIGS. 4, 8, 12, and 26. The housing 12 is an assembly of an upper housing portion 18 with front surface 16, and a lower housing portion 19 providing base 13. Sandwiched between portions 18 and 19, which mate along the edges thereof, is a circuit board 20 having an array of light sources 20a, such as LEDs, with electronics coupled to wires 22, and a gasket member 23 of flexible elastomeric material, such as rubber. Each light source 20a should be disposed to provide light to a lens element 17, such as a Fresnel lens, along front surface 16. Such Fresnel lens may be similar to lens elements 17a as shown in FIG. 27. However, front surface 16 may have other optics for desired shaping of light from light sources 20a. For example, wires 22 connect to circuit board 20 to provide power and/or control to light sources 20a. Lens or lens elements 17 and light sources 20a provide the optical system of lamp 10. As best shown in FIG. 26, screws 24 are received in holes 21 along circuit board 20 to mount the circuit board into threaded holes 29a of lower portion 19. Screws 25 are received through holes 26 and 27 of lower portion 19 and gasket member 23, respectively, and tightened in threaded holes 28 of upper portion 18, to complete the assembly of housing 12. When assembled, wires 22 extend through an opening 29 in lower housing portion 19. Gasket member 23 provides a seal between upper and lower portion 18 and 19. Light sources 20a are of wattage which does not generate enough heat that would require a heat sink in housing 12. The assembled housing 12 has an exterior flange, projecting ridge, or step 14a along sides 14 of lower housing portion 19, as best shown in the FIGS. 4 and 8. The upper housing portion 18 along with integrated lens or lenses 17, and lower housing portion 19, may be made of molded plastic material.

(18) Lamp 10 is thin, such as for example having a height from its base 13 to front surface 16 of inches, with housing 12 being of that height, and lens or lens elements 17 along front surface 16 extending a height of inches. Housing 12 for example may have a diameter of 4.4 inches, but other diameters may be used. The thinness of lamp 10 is enabled by avoiding the need for a heat sink in housing 12. For example, lamp 10 may be of PAR 36 type lens, such as shown, for example, in U.S. Design patent application Ser. No. 29/374,905, now U.S. Pat. No. D693,035, but other lenses may be used to provide the desired projected illumination from the lamp. The shape of the housing (e.g., thickness and outer sides) is such that it may be received in one of multiple mounting members (or fixtures) 30a, 30b, and 30c, as described below in connection with FIGS. 1-4, 4A, 5-8, and 9-12, respectively.

(19) Referring to FIGS. 1-4, mounting member 30a is shown for enabling on-surface mounting mode of lamp 10 so that it lies flush onto an exterior surface 40 of a vehicle body wall 41. Mounting member 30a represents a rigid tray, such of molded plastic material, having a bottom wall 36a which meets inner or interior wall 36b, and an outer or exterior wall 36c which meets interior wall 36b along a rounded edge 36d at the front end of mounting member 30a. The outer wall 36c may be of a frusto-conical shape in that it forward slopes and tapers in diameter to round edge 36d, while interior wall 36b tapers in diameter from round edge 36d to bottom wall 36a. There is thus a general triangular cross-sectional shape along walls 36b and 36c with an open ended cavity there between, as best shown in FIG. 4.

(20) The surface of mounting member 30a along interior wall 36b is sized to receive sides 14 of housing 12 and retained therein by clips (or clip members) 32 to capture housing 12 along portions of its flange 14a as shown in FIG. 4. A front view of mounting member 30a is shown in FIG. 4A, showing for example four clips 32 spaced at different locations along wall 36a. Each clip 32 has an inwardly extending tab portion 33 which is downwardly sloped. The diameter of member 30a along interior wall 36b is larger than the outer diameter of lamp housing 12 so as to facilitate engagement of clips 32 of housing 12 when received in mounting member 30a. As shown in FIG. 1, a pad 34, such as of foam material, is placed along the interior surface of bottom wall 36a of mounting member 30a so as to provide a forward bias onto base 13 so that tab portion 33 of each of clips 32 lies against flange 14a when housing 12 is received in mounting member 30a.

(21) For example, outer wall 36c may be 5.1 inches in diameter at lower end of mounting member 30a and 4.9 inches in diameter at round edge 36d, while interior wall 36b may be 4.5 inches in diameter at rounded edge 36d, and 4.4 inches in diameter when meeting bottom wall 36a, where walls 36a-c may each be 1/16 inches thick. However, other dimensions may be used if desired so long as lamp 10 can engage clips 32 when received in member 30a.

(22) Prior to placement of lamp 10 in mounting member 30a, the mounting member 30a is disposed over surface 40 with a pad 38 of flexible elastomeric material, such as rubber, between surface 40 and exterior surface of bottom wall 36a of mounting member 30a. The outer diameter of pad 38 is preferably the same, or slightly larger than, the outer diameter of mounting member 30a at lowest end of outer wall 36c, as shown in FIGS. 1 and 4. The pad 38 provides sealing material between the back of mounting member 30a and surface 40. Fasteners provided by screws 38a and nuts 38c are used to install mounting member 30a with pad 38 onto surface 40. Four screws 38a are then received via holes 37 in bottom wall 36a of mounting member 30a, and holes 38b in pad 38, into holes 39a drilled into surface 40, and retained by nuts 38c (see FIGS. 1 and 4). Lamp 10 is placed in mounting member 30a until flange 14a passes and pushes outwardly upon inwardly extending tab portions 33 of clips 32 until such portions of flange 14a facing tab portions 33 are captured under tab portions 33 under the forward bias of compressed pad 34. When mounted, wires 22 extend through an opening 34a of pad 34, an opening 35 of mounting member 30a, an opening 38d of pad 38, and then an opening 39b drilled in surface 40.

(23) The completed mounting of lamp 10 with mounting member 30a, along with pads 34 and 38, is shown in FIGS. 3, and 4. A portion of lens or lens elements 17 of front surface 16 may extend from mounting member 30a, if desired. In this manner, lamp 10 is flush mounted onto (and over) surface 40 with pad 38 there between for on-surface mounting with a bezel mounting appearance.

(24) Referring to FIGS. 5-8, mounting member 30b is shown for enabling inset mounting mode of lamp 10 in a drilled hole or opening 42 extending through exterior surface 40 of a vehicle body wall 41. Mounting member 30b is a generally cylindrical shaped grommet of flexible elastomeric material, such as rubber. For example, mounting member 30b may be a Model 60 Mounting Grommet manufactured by Truck-Lite Company LLC, but grommets of other manufacturers may be used which are similarly adapted to the shape of housing 12. Mounting member 30b has a lower portion 44 and a upper portion 45, where lower portion 44 is insertable into opening 42 and upper portion 45 extends to frame about opening 42 along surface 40. Lower portion 44 has a ledge 47a which presses against side wall 43 of hole 42 to retain mounting member 30b in opening 42. An exterior ridge 47b may also be provided along lower portion 44 to frictionally engage side wall 43 if thicker than shown in FIG. 8. Upper portion 45 has three walls 49, 50, and 51 which provide a frame upon surface 40. Walls 49 and 51 are generally parallel to each other, and wall 50 connects walls 49 and 51 and is generally perpendicular thereto, as best shown in FIG. 8. Wall 49 of upper section 45 extends continuously with the surface of an interior wall 48 of lower section 44. Wires 22 from lamp 10 extend through opening 54 of mounting member 30b when lamp 10 is received in mounting member 30b.

(25) As shown in FIG. 8, mounting member 30b is sized along its interior walls 48 and 49 so as to frictionally engage housing 12 of lamp 10 when received therein so that flange 14a engages wall 48 of lower portion 44, and base 13 of the lamp is disposed along interior of bottom ledge or wall 46 of mounting member 30b. Mounting member 30b with lamp 10 received therein is pressed into opening 42 so that its ridge 47b and ledge 47a deform to engage the opening's wall 43, and edge 52 from wall 51 of the upper portion 45 lies against surface 40 providing an annual cavity 53 between walls 49-51, thereby retaining the assembly of the mounting member 30b and lamp 10 in opening 42 inset in surface 40 and also sealing opening 42 from the external environment. The completed mounting of lamp 10 with mounting member 30b is shown in FIGS. 6, 7, and 8, where wall 41 is removed in FIGS. 6 and 7.

(26) Referring to FIGS. 9-12, mounting member 30c is shown for also enabling inset mounting mode of lamp 10 in a drilled hole or opening 42 extending through exterior surface 40 of a vehicle body wall 41. Mounting member 30c is a circular bracket which may be made of stainless steel, such bracket may be for example Model No. 97334 Security Flange manufactured by Truck-Lite Company LLC. Mounting member 30c has a lower surface 55 having legs 58 extending there from generally perpendicular with respect to the lower surface 55. Each leg 58 has an interior clip member 60 which captures the rear of lamp housing 12, i.e., at a location along the outer periphery of base 13, when the lamp 10 is pressed into mounting member 30c from the back side thereof to retain lamp 10 to mounting member 30c. Each leg 58 further has two exterior clip members 61 which clip under the back surface 62 of wall 41 below opening 42 when the mounting member 30c with lamp 10 received therein is pressed into opening 42 of surface 40.

(27) When the assembly of lamp 10 and mounting member 30c is received in opening 42, lower surface 55 of the mounting member 30c partially lies flat against surface 40 about opening 42, i.e., over radial distance between legs 58 and the outer edge 57 of the mounting member 30c. The upper surface 56 of mounting member 30c then lies generally parallel to the surface 40 providing a trim appearance with the lamp inset surface mounting to the vehicle body wall 41.

(28) Although the above round housing 12 is described above, other lamp housing shapes may be provided which can be similarly received in mounting members 30a, 30b, and 30c adapted to the particular housing shape. For example, a lamp 10a with an oval housing 12a may be provided with an upper housing portion 18a mating a lower housing portion 19a, lens or lens elements 17a along a front surface 16a, sides 67, a base 13a, and a flange, ridge or step 68, such as shown in FIGS. 13-25 which is mountable in oval mounting members 30d, 30e, and 30f in the same manner as described above for mounting members 30a, 30b, and 30c, respectively, as in the case of a round lamp housing 12, and thus have like numerals.

(29) In particular, mounting member 30d provides an oval tray for on-surface mounting lamp 10a with oval shaped pads 34 and 38 by fasteners 38a and 38c, as shown in FIG. 13-17, in the same manner as described earlier for mounting member 30a. A flange 68 is provided along lamp 10a and provides the same function as flange 14a of lamp 10, such as to engage clips 32 by tab portions 33 when placed in mounting member 30d. However, one difference is that the number and position of clips 32 along mounting member 30d differ due to the oval shape of housing 12a. For example, three clips 32 are provided at spaced locations from each other, two along one side and one on the other side for mounting member 30d as shown in FIG. 17.

(30) Mounting member 30e provides an oval shaped grommet of elastomeric material for receiving lamp 10a as shown in FIGS. 18-21 in same manner as mounting member 30b, but in an oval shaped opening or hole 42. Thus, when lamp 10a is received in mounting member 30e, interior wall 48 engages the outer sides of housing 12a, including flange 68.

(31) Mounting member 30f provides an oval bracket for inset mounting lamp 10a as shown in FIGS. 22-25 in the same manner as mounting member 30c, but in an oval shaped opening or hole 42. However, one difference is that the number and position of legs 58 along mounting member 30f differs due to the oval shape of housing. For example, six legs 58 are provided at spaced locations from each other as shown in FIG. 22.

(32) The assembly of lamp 10a is shown in FIG. 27, and other than difference in shape of components, such assembly is similar to that described earlier for lamp 10. In particular, housing 12a is an assembly of upper housing portion 18a with front surface 16a, and lower housing portion 19a providing base 13a. Flange 68 extends along the outer periphery of the surface of lower housing portion 19a. Sandwiched between portions 18a and 19a, which mate along the edges thereof, is a circuit board 20b having an array of light sources, such as LEDs, facing front surface 16a with electronics coupled to wires 22, and a gasket member 23a of flexible elastomeric material, such as rubber. The light sources on circuit board 20b are the same as light sources 20a shown in FIG. 26 and are spaced from each other to direct light to lens elements 17a, which may be Fresnel lenses. However, front surface 16a may have other optics for desired shaping of light from light sources 20a. Screws 24a are received in holes 21a along circuit board 20b to mount the circuit board into threaded holes 29c of lower portion 19a. Such attachment of the circuit board to lower housing portion 19a may be the same as screws 24 via holes 21 to threaded holes 29a of lamp 10. Screws 25a are received through holes 26a and 27a of lower housing portion 19a and gasket member 23a, respectively, and tightened in threaded holes 28a of upper housing portion 18a, to complete the assembly of housing 12a. When assembled, wires 22 extend through an opening 29b in lower housing portion 19a. The upper and lower portions 18a and 19a may be made of molded plastic.

(33) From the foregoing description it will be apparent that there has been provided a system for mounting a lamp with respect to a surface along a vehicle. Variations and modifications herein this described system, apparatus, and method will undoubtedly suggest themselves to those skilled in the art. Accordingly the foregoing description should be taken as illustrative and not in a limiting sense.
