DETAILED DESCRIPTION
Turning now to the Figures, illustrated are various embodiments of components that are usable to construct a lamp holder for holding a source of LED light. By way of example only, Figs. 1 and 2 illustrate a lamp holder 10 for holding a source of LED light 12 comprised of a lamp holding component 14 with optional cover component 16, a mounting surface 18, which may be a heat sink, electrical contacts 20 (for engaging corresponding contacts of the source of LED light 12 when the source of LED light 12 is inserted into the lamp holding component 14), and fasteners 22 (for removeably securing the lamp holding component 14 - and the optional cover component 16 - to the mounting surface 18). While not limiting, the lamp holder 10 may be placed within a can enclosure
or luminaire such as commonly used in overhead lighting fixtures. Furthermore, the optional cover component 16 and/or the lamp holding component 14 can be adapted to be coupled with or otherwise be provided with additional optical components as desired, e.g., a lens to provide desired light dispersion characteristics, etc., and can be sized and arranged as necessary to accommodate sources of LED light of varying shapes and sizes. Preferably, at least the lamp holding component 14 and the cover component 16 are formed from a plastic material. It will be understood that other materials may also be utilized as needed for any particular purpose, e.g., metal materials that are resistant to plastic creep issues could also be utilized for one or more of the components. Yet further, the fasteners 22 can be releasably matable with the mounting surface 18 (for example by providing the fasteners 22 with threads or the like) or be formed as an integral part of the mounting surface 18.
For releasably securing the lamp holding component 14 and the optional cover component 16 to the mounting surface 18 (and thereby the LED lamp assembly 12 between the lamp holding component 14 and the mounting surface 18), the lamp holding component 14 and the cover component 16 are provided with one or more keyed openings 24. As particularly illustrated in Fig. 3, the keyed openings 24 include a first portion 24A, which is sized to accept the head portion 22A of a corresponding fastener 22, and a second portion 24B, which is sized smaller than the head portion 22A of the corresponding fastener 22. The lamp holding component 14 and/or the optional cover component 16 is thus secured to the mounting surface 18 by positioning the fasteners 22 within the first portion 24A of the keyed opening 24 and by then twisting, sliding, or otherwise moving the lamp holding component 14 and/or optional cover component 16 relative to the fasteners 22 such that the head portion 22A of the fasteners 22 is moved into the smaller sized second portion 24B of the keyed openings 24, i.e., the lamp holding component 14 and/or the optional cover component 16 is moved such that the upper surface of the lamp holding component 14 and/or the optional cover component 16 becomes engaged with the underside of the head portion 22 A of the fasteners 22. As will be appreciated, such an arrangement allows the holding component 14 and/or the optional cover component 16 to be removed from the mounting surface 18 without also requiring the removal of the fasteners 22 from the mounting surface 18 (in the event that the fasteners 22 are also releasably secured to the mounting surface 18).
To releasably lock at least the lamp holding component 14 to the mounting surface 18, the keyed openings 24 of at least the lamp holding component may be
provided with tabs 24C that function to inhibit the fasteners 22 from exiting the second portion 24B of the keyed opening 24. As illustrated in Fig. 3, the tabs 24C may be in the form of bumps or the like that protrude inwards into the keyed opening 24 intermediate the first portion 24 A and the second portion 24B. As will be appreciated, the illustrated bumps would be capable of being moved outwardly relative to the keyed opening 24 when the fastener 22 is forced thereover owing to the resilient or deformable nature of the plastic used in constructing the lamp holding component 14. In other embodiments, the tabs 24C could take the form of springs or the like without limitation. As will also be appreciated, similar structure could be provided to the cover portion 16 to serve this same purpose.
To assist in urging a LED lamp assembly 12 disposed in the holding component 14 against the mounting surface 18 when the holding component 14 is secured and locked to the mounting surface 18, the keyed opening 24 may then be provided with inclined surfaces 24D. As seen in Fig. 3, the inclined surfaces 24D slope generally upward from the first portion 24A to the second portion 24B of the keyed opening 24 such that, when the holding component 14 is moved relative to the fasteners 22 towards the locked position, the underside of the head portion 22A of the fasteners engages with the inclined surfaces 24D and increasingly more force is provided upon the lamp holding component 14 as it is further moved to thereby increasingly force or drive the lamp holding component 14, and the lamp LED lamp assembly 12 carried thereby, towards the mounting surface 18.
To assist a user in moving the lamp holding component 14 and/or the optional cover portion 16 relative to the fasteners 22, the lamp holding component 14 and/or optional cover portion 16 may be provided with one or more finger grasping portions 26 as illustrated in Fig. 4. The one or more finger grasping portions 26 may be in the form of arcuately shaped indentations and may be provided to opposed sides of the holding component 14 and/or optional cover portion 16 as particularly illustrated. As will be understood, the use of indentations as finger grasping portions 26 may be desirable as such indentions function to limit the need for any additional structures that might interfere with the optical elements of the assembly. Nevertheless, in certain circumstances and as need for a given purpose, such finger grasping portions 26 could be in the form of low- profile protuberances or the like that extend outward from the sides of the holding component 14 and/or optional cover portion 16, may be in the form of low-profile protuberances or the like the extend upwardly from a top surface of the holding
component 14 and/or optional cover portion 16, and the like without limitation. In any case, what is desired is to provide a non-smooth or non-slip feature to a surface to the holding component 14 and/or the optional cover portion 16 that can be conveniently grasped by a user to thereby move the holding component 14 and/or the optional cover portion 16 relative to the fasteners 22.
For allowing electrical connections to be made with a LED light source 12 disposed within the lamp holding component 14, electrical terminals 20 are provided. As particularly shown in Figs. 2, 5, and 6, the electrical terminals 20 are securely mounted to the lamp holding component 14 and include one or more electrical connection points 20 A as well as one or more contacts 20B that are arranged to engage with corresponding electrical contacts formed on the source of LED light (as shown in Fig. 7). The electrical connection points 20A may incorporate any known structure to thereby allow an electrical lead to be engaged therewith. By way of non-limiting example, an electrical lead may be soldered to, pushed-into, crimped on, etc. to the electrical connection points 20A. Leads connected to the electrical lead junction points 20A will preferably exit from side openings 14A provided to the lamp holding component 14.
For urging the source of LED light 12 against the mounting surface 18, the contacts 20B are preferably mounted to the electrical terminals 20 via use of a resilient arm 20C. In the example illustrated in the figures, the contacts 20B are formed on a leaf spring that is an integrally formed portion of the electrical terminals 20 and which provides an axial downward force upon the source of LED light 12. As further illustrated, each leaf spring is arranged to provide a distributed force upon the source of LED light 12 with at least one side of the leaf spring actually providing an electrical connection with a corresponding electrical contact of the source of LED light 12. It will be appreciated that further resilient devices can be used in place of the illustrated leaf spring to provide a similar downward force upon the source of LED light 12 and, as such, the illustrated arrangement is not meant to be limiting.
To provide an electrical connection, e.g., a grounding electrical connection, between the source of LED light 12 and the mounting surface 18 or other conductive part within a luminaire which includes the lamp holder 10, a single piece, contact 28 may be provided as illustrated in Fig. 7. While not intended to be limiting, the single piece contact 28 provides a first portion 28A arranged to contact a corresponding contact of the source of LED light 12 and a second portion 28B which is arranged to contact the mounting surface 18 when the holding component 14 is secured thereto. The contact 28
is preferably constructed of a resilient material such that the first portion 28A and the second portion 28B are urged into contact with the source of LED light 12 and mounting surface 18, respectively.
For positioning a source of LED light 12 within the lamp holding component 14, particularly to hold the source of LED light 12 within the lamp holding component 14 before the lamp holding component 14 is mounted to the mounting surface 18 and to further urge the source of LED light 12 towards the mounting surface 18 when the lamp holding component 14 is secured to the mounting surface 18, the lamp holding component 14 is provided with one or more, e.g., a pair of oppositely positioned, holding elements 30. As particularly illustrated in Fig. 6 by way of example only, a pair of holding elements 30 may be arranged so as to engage opposed sides of the source of LED light 12 when the source of LED light 12 is inserted therebetween. While not required, the one or more holding elements 30 are illustrated as being carried by one or more resilient arms 32 which allow the one or more holding elements 30 to move in multiple directions A, B, and C as illustrated in Fig. 6. The one or more holding elements 30 may also be generally pivotable about their point of connection with the one or more resilient arms 32. In this manner, the one or more holding elements 30 may deflect as necessary to engage the sides of the source of LED light 12 when the source of LED light 12 is positioned within the lamp holding component 14 and, thereafter, to apply a force upon the sides of the source of LED light 12 to thereby hold the source of LED light 12 within the lamp holding component 14. The insertion of the source of LED light 12 into the lamp holding component 14, particularly between the one or more holding elements 30, may be further facilitated by providing the one or more holding elements 30 with chamfered edges 3 OA. While the one or more holding elements 30 and the one or more resilient arms 32 are shown as being integrally formed with the lamp holding component 14, it will be appreciated that multiple components could also be utilized, e.g., the one or more holding elements 30 could be mounted to further provided springs or the like. As further illustrated in Fig. 6, the one or more holding elements 30 are preferably arranged to extend out of the lamp holding component 14 to thereby expose at least a portion of the source of LED light 12 which thereby allows the source of LED light 12 to be easily grasped for insertion into or removal from the lamp holding component 14. In addition, when the lamp holding component 14 is secured to the mounting surface 18, the resilient nature of and arrangement of the one or more holding elements 30 allows the source of LED light 12 to be positioned against the electrical contacts 20 while also allowing the
one or more holding elements 30 to urge the source of LED light 12 against the mounting surface 18.
While specific embodiments of the subject invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of this disclosure. For example, Fig. 8 illustrates a single piece lamp holder 10' which does not utilize a cover but having many of the components described above, e.g., keyed openings 24, electrical contacts 20 snapped, press-fit, or the like to the holding component, resilient holding elements 30, etc. It will therefore be appreciated that features described with respect to the various embodiments are not to be limited to any particular embodiment but may be freely used across embodiments where applicable. Additionally, it will be appreciate that the size, shape, arrangement, and/or number of components illustrated and described can be changed as necessary to meet a given need. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention which is to be given the full breadth of the appended claims and any equivalents thereof.
