BACKGROUND OF THE INVENTION

Semiconductor light emitting diodes (LEDs) have been widely used for decorative lighting, especially on holidays. LED light strings are inexpensive, have superior physical properties, including low operating voltage and power, small size, long lifetime, and a high degree of stability. Further, LEDs do not operate at high temperatures and do not generate the heat of normal incandescent bulbs, and as such, provide a safer source of decorative lighting.


SUMMARY OF THE INVENTION

An embodiment of the present invention may therefore comprise a method of assembling a substantially inseparable LED lamp assembly from individual discrete components comprising: providing a lamp holder that is formed as an annulus with a first opening on a first end of the annulus and a second opening on a second end of the annulus; substantially permanently securing a lamp cover to the first end of the annulus so that the lamp cover is substantially inseparable from the lamp holder and forms a watertight seal with the lamp holder; providing an LED lamp having LED pin leads; attaching wires directly to the LED pin leads of the LED lamp that have a predetermined size and a predetermined shape; inserting the LED lamp through the second opening of the second end of the annulus to a position where the LED lamp is oriented to allow light from the LED lamp to be transmitted through the lamp cover; substantially permanently attaching the LED lamp directly to the annulus so that the LED lamp is substantially inseparable from the annulus; inserting a plug into the second opening of the second end of the annulus, the plug having indentations along an outer surface that substantially match the predetermined size and the predetermined shape of the wires so that the plug forms a watertight seal with the wires; substantially permanently sealing the plug in the second opening to form a watertight seal at the second end of the annulus.


An embodiment of the present invention may further comprise an LED lamp assembly that is constructed of individual components that are separately fabricated and are assembled to provide a substantially inseparable LED lamp assembly comprising: a lamp holder that is shaped as an annulus, the annulus having a first opening on a first end and a second opening on a second end; a lamp cover substantially permanently attached to the first end of the annulus so that the lamp cover is substantially inseparable from the lamp holder and a watertight seal is formed between the lamp cover and the lamp holder; an LED lamp inserted through the second opening of the annulus and substantially permanently attached in the annulus so that the LED lamp is substantially inseparable from the lamp holder and forms a watertight seal with the lamp holder in a position that orients the LED lamp to allow light to be transmitted through the lamp holder, the LED lamp having LED lead pins attached to the LED lamp; wires that are conductively connected directly to the LED lead pins and extend through the second opening of the second end of the annulus, the wires having a predetermined size and shape; a plug having indentations along an outer surface that substantially match the predetermined size and shape of the wires, the plug substantially permanently inserted in the second opening to prevent disassembly of the LED lamp assembly and to create a watertight seal between the plug and the second opening in the annulus.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION


FIG. 1 is a schematic illustration of an embodiment of an LED lamp assembly 100. Generally, there are two types of LED light strings, i.e. light strings that have separable lamps and light strings that have inseparable lamps. Separable lamps allow a user to disassemble the lamp and replace the LED or other parts that are not functioning. In addition, separable LED lamps have the advantage of allowing the manufacturer to separately manufacture the pieces for later assembly. Manufacturing of discrete components allows for flexibility in production and assembly. The disadvantage of having LED strings with separable lamps is that portions of the lamp assembly can become disassembled during shipping or installation, so that the LED string becomes either partially or wholly inoperable. Further, separable LED lamps are subject to theft and vandalism. This problem is compounded in series wired LED strings, in which the entire string fails to light if a single LED becomes disconnected. For example, if a removable LED string becomes accidentally disconnected during shipping or installation, the entire string will fail to light.


Inseparable LED strings avoid many of the problems associated with LED strings made from separable LED lamps. Inseparable LED lamps are not subject to accidental disconnection, theft or vandalism, for the most part, because the LEDs are hardwired into the LED string and overmolded in injection molding machines. In other words, the LED lamps are soldered directly to the wires of the lighting string and are then overmolded in an injection molding machine. The disadvantage of this process is that it is expensive to individually overmold each LED lamp using injection molding devices and to perform the final assembly of the components at the injection molding machine site. Further, the high temperatures used in the injection molding process often damage the LED lamps, resulting in low yield. If a single LED lamp is damaged in a series wired LED light string during the injection molding process, the entire light string will be inoperable.


Various embodiments are disclosed herein that provide a substantially inseparable lamp that is fabricated from discrete parts that can be separately manufactured and later assembled in a substantially inseparable lamp assembly that overcomes many of the disadvantages of both separable and inseparable LED lamp assemblies. As used herein, the terms “substantially inseparable” means that the LED lamp assembly is not separable by hand using forces that can be manually generated, or without the use of special tools. Of course, everything is separable if sufficient force is applied. However, damage may result to the lamp assembly from the application of forces that exceed normal manual forces that can be generated by hand.


Referring again to FIG. 1, the LED lamp assembly 100 includes a lamp cover 102, having a lamp base 104 that is adapted to fit in an annular slot 108 of the lamp holder 106. The lamp base 104 may have a size and shape such that there is an interference fit between the lamp base 104 and the annular slot 108. The interference fit allows the lamp base 104 to be inserted in the annular slot 108 in a manner that substantially prevents removal of the lamp cover 102. When the lamp base 104 is inserted into the annular slot 108, forces are created on the material of the inner wall of the annular slot 108 that create a force against the LED diode body 112. The force of the inner annular wall 128 on the LED diode body 112 may create an interference fit or assist in securing a bond 130 that may be formed between the LED body 112 and the inner wall surface 120. The bond between the lamp base 104 and the annular slot 108 can be formed using an adhesive, a solvent, or thermal welding, including sonic welding.


As also illustrated in FIG. 1, the LED lamp assembly 100 includes an LED lamp 111 that is secured to a first opening in the lamp holder 106. The lamp holder 106 may be formed as an annulus, having various shapes. Lamp base 104 may be a round annulus or other shape that matches the lamp holder 106. LED lamp 111 has an LED diode body 112 that is secured to the inner wall 120 of the annulus of the lamp holder 106. The LED diode body 112 may be secured to the inner wall 120 by an interference fit or by bonding the LED diode body 112 to the inner wall 120. Various bonding techniques can be used, including adhesive bonding, thermal bonding, including sonic bonding, or other various techniques, including the use of solvents. The LED diode body 112 is secured to the inner wall 120 so that the LED lens 110 protrudes from the first opening of the lamp holder 106 and emits light in the lamp cover 102 when the lamp cover 102 is substantially inseparably attached to the lamp holder 106.


The LED lamp assembly 100 of FIG. 1 also includes a plug 114. Plug 114 is inserted into the second opening of the lamp holder 106 and creates an interference fit with the inner wall 120 of the second opening of the lamp holder 106. Wires 116, 118 are disposed in grooves (disclosed below in FIGS. 2-4) that have an arcuate shape and that allow the plug 114 to fit tightly within the second opening of the lamp holder 106 and provide a substantially water resistant or watertight fit that prevents water and other contaminants from entering the interior portion of the annulus of the lamp holder 106. The plug 114 can be made of a malleable elastic-type material that allows deformation of plug 114 to create an interference fit and substantially seal the second opening of the lamp holder 106. Alternatively, the material of the lamp holder 106 can be made of a malleable material, so that the inner wall 120 of the lamp holder 106 creates a seal around a plug 114 made of a harder material. Alternatively, plug 114 can be bonded to the inner wall 120 using an adhesive bond, a thermal bond, including a sonic bond, or a bond created by a solvent. Wires 116, 118 are attached to LED pin leads 124, 126, respectively, to complete the electrical circuit with the LED lamp 111. Plug 114 may also include a plug extension 122 that is made from an insulating material that assists in preventing wires 116, 118 from touching and causing a short circuit. Alternatively, wires 116, 118 can be fed through round openings (not shown) in the body of plug 114. Such openings would allow the wires 116, 118 to be fed through the plug 114 and provide a seal between the wires 116, 118 and the openings to prevent moisture or other contaminants from entering the lamp holder 106. The process of feeding the wires 116, 118 through the plug 114 would necessarily occur prior to attachment of the wires 116, 118 to LED pins 124, 126.


The advantage of the LED lamp assembly 100 illustrated in FIG. 1 is that each of the elements can be manufactured separately and then later assembled into the LED lamp assembly 100, which is substantially inseparable. In other words, the LED lamp assembly cannot be disassembled without either damaging the LED lamp assembly, or using excessive force or specialized tools.



FIG. 2 is a schematic isometric drawing of a plug 200. Plug 200 may be similar to plug 114 illustrated in FIG. 1. Grooves 202, 204, that have an arcuate shape, are formed in the exterior surface 206 of the plug 200 to allow space for the wires, such as wires 116, 118, to be inserted into the second opening of the lamp holder 106. The plug 200 biases the insulation of the wires 116, 118 towards the inner wall surface 120 of the lamp holder 106 and substantially surrounds and seals the wires 116, 118.



FIG. 3 is an end view of the plug 200 illustrated in FIG. 2. As shown in FIG. 3, plug 200 includes grooves 202, 204 that have an arcuate shape and are indented sufficiently to allow the wires, such as wires 116, 118, to be biased to the inner wall of the lamp holder and sealed in the second opening of the lamp holder 106. Generally, the material of the plug 200 is sufficiently malleable and elastic to surround the wire sufficiently to substantially create a seal with the lamp holder 106. Fillers and adhesive fillers may be used to ensure that a watertight seal is created using plug 200.



FIG. 4 is a cross-sectional view of FIG. 3. As shown in FIG. 4, plug 200 includes the grooves 202, 204.



FIG. 5 is an isometric view of another embodiment of a plug 500. Plug 500 has three grooves 502, 504, 506 that are formed in the exterior surface 508 of the plug 500. Three wires may be required to wire LED lamps in a parallel configuration in a lighting string, which necessitates the use of three grooves in plug 500.



FIG. 6 is an end view of plug 500 of FIG. 5. Grooves 502, 504, 506 are formed in the exterior surface 508 to allow three wires to be inserted in the second opening of the annulus of the lamp holder. Grooves 502, 504, 506 have a shape and size that allows the wires to fit around the plug in the second opening of the lamp holder. Again, plug 500 is sufficiently malleable to create a substantially watertight seal in the second opening of the lamp holder.



FIG. 7 is a cross-sectional view of FIG. 6. As shown in FIG. 7, plug 500 includes a groove 502 in the exterior surface 508 of plug 500.



FIG. 8 is a schematic illustration of another embodiment of an LED lamp assembly 800. As shown in FIG. 8, lamp cover 502 has a lamp base 504 that is inserted in a recessed annulus 508 of the lamp holder 506. The recessed annulus may create an interference fit between the lamp base 504 and the recessed annulus 508, or a bond 522 may be created between the recessed annulus 508 and the lamp base 504. The LED lamp 511 has an LED diode body 512 that is attached to the inner wall 520 of the lamp holder 506. The LED diode body 512 can be attached to the inner wall 520 by an interference fit or by a bond 528, including an adhesive bond, a solvent bond, or a thermal bond, including a sonic bond. The diode body 512 is attached so that the LED lens 510 is disposed within the lamp cover 502 to emit light from the lamp cover 502. The LED lamp 511 has LED pin leads 524, 526 that are connected to wires 516, 518, respectively. Plug 514 may be similar to plug 200 of FIG. 2, or plug 500 of FIG. 5, which have grooves along the outer surface that allow the plug 514 to be inserted after wires 516, 518 are connected to the LED pin leads 524, 526. Plug 514 may be made of a malleable, elastic-type of material that easily deforms and can be made larger than the second opening in the lamp holder 506, so that a seal is created between the plug exterior surface 530 and the inner wall 520, as a result of an interference fit between the plug 514 and the second opening in the lamp holder 506. Alternatively, plug 514 can be bonded to the lamp holder 506 using adhesives, adhesive fillers, thermal bonds, including sonic bonds, or solvent bonds. Once the LED lamp assembly 800 is fully assembled, it is substantially inseparable.



FIG. 9 is a schematic illustration of another embodiment of an LED lamp assembly 900. The LED lamp assembly 900 illustrated in FIG. 9 shows the use of barbs 906 disposed on the lamp base 904 of the lamp cover 902 that interface with barb sockets 912 that are disposed in the annular slot 910 of lamp holder 908. When the lamp base 904 is inserted into the annular clot 910, the barbs 906 engage with the harp sockets 912 to prevent removal of the lamp cover 902 from the lamp holder 908. The barbs 906 and barb sockets 912 can be disposed on either the lamp base 904 or the annular slot 910, as desired. The barbs 906 and barb sockets 912, or other types of interference mechanisms, can be used in any of the embodiments to enhance an interference fit, including interference fits between the lamp base and the lamp holder, the LED diode body and the interior wall surface of the lamp holder, or the plug to the interior surface of the lamp holder, as desired. The use of barbs 906 and barb sockets 912 increase the effectiveness of an interference fit, as described herein, but are not required to create an interference fit. Further, the interference fit that either uses or fails to use barbs and barb sockets can be further aided in forming a substantially inseparable connection through the additional use of a bond.



FIG. 10 is a schematic illustration of another embodiment of an LED lamp assembly 1000. As shown in FIG. 10, lamp cover 1002 has a lamp base 1004 that is inserted in a first opening of lamp holder 1006. The lamp base 1004 may have an interference fit with the inner wall 1020 of the lamp holder 1006, which holds the lamp base 1004 and the lamp cover 1002 securely within the lamp holder 1006. The interference fit can constitute a simple friction fit, or may employ other interference mechanisms, including the barbs and barb sockets illustrated in FIG. 9. Alternatively, bond 1008 can be used to secure the lamp base 1004 to the interior wall 1020 of the lamp holder 1006. Bond 1008 can be an adhesive bond, a thermal bond, including a sonic bond, or a bond formed by solvents.


As also shown in FIG. 10, the LED diode body 1012 is secured to the interior surface of the lamp base 1004, rather than inner wall 1020 of the lamp holder 1006. The LED diode body 1012 can be held in the lamp base 1004 by an interference fit, as described herein, or by a bond 1022. Again, the bond may comprise an adhesive bond, a thermally formed bond, such as a sonic bond or other thermal bond, or a bond formed by a solvent. Plug 1014 illustrated in FIG. 10, may have an interference fit with the interior wall 1020 of the lamp holder 1006, or may be held in place by a bond 1028, in the manner described above. Wires 1016, 1018 are connected to LED pin leads 1024, 1026. Wires 1016, 1018 are inserted through the second opening of the lamp holder 1006 and may engage the plug 1014 in any of the ways described herein to form a seal in the second opening of the lamp housing 1006.



FIG. 11 is a schematic illustration of another embodiment of an LED lamp assembly 1100. As shown in FIG. 11, lamp assembly 1100 includes a lamp cover 1102 that has a lamp base 1104. Lamp base 1104 is adapted to fit into the annular slot 1108 formed in the lamp holder 1106. Lamp base 1104 may create an interference fit with the annular slot 1108 or may be bonded to the annular slot 1108, as described with respect to the other embodiments disclosed herein. As also shown in FIG. 11, the LED diode body 1112 of the LED 1110 is attached to an LED clip 1122. The LED diode body 1112 can be attached to the LED clip 1122 with a bond or an interference fit. LED clip 1122 has hooks 1124, 1126 that engage the shoulder 1128 on the inner wall 1120 of the lamp holder 1106. The LED 1110, which is attached to the LED clip 1122, can be inserted through the second opening on the left side of the lamp holder 1106, as illustrated in FIG. 11, until hooks 1124, 1126 engage shoulder 1128. At that point, the LED 1110 extends outwardly from the first opening of lamp holder 1106 sufficiently to project light through the lamp cover 1102 when the lamp cover 1102 is attached to the lamp holder 1106. Plug 1114 is inserted in the second opening of the lamp holder 1106 until the plug 1114 abuts against the hooks 1124, 1126. When the plug 1114 is securely attached to the lamp holder 1106, the plug 1114 holds the hooks 1124, 1126 in place in the lamp holder 1106. In other words, the plug 1114 causes the hooks 1124 to abut against the shoulder 1128 to hold the LED lamp 1110 in the proper location in the LED lamp assembly 1100. Wires 1116, 1118 extend through the second opening in the lamp holder 1106 and can interface with the plug 114 in any of the ways disclosed herein.



FIG. 12 is a schematic illustration of another embodiment of an LED lamp assembly 1200. As shown in FIG. 12, plug 1210 has a unique configuration. Plug 1210 has a plug extension 1212 that extends between the wires 1206 and 1208 to prevent accidental contact of those wires. Plug 1210 has grooves 1214, 1216 that allow the wires 1206, 1208, respectively, to extend through the body of the plug 1210. Plug 1210 can be securely attached to lamp holder 1204 using an interference fit or a bond, as described herein.



FIG. 13 is an end view of the plug 1210 illustrating the manner in which the wires 1206, 1208 extend through the plug 1210. The inside wall 1214 of the lamp holder is also illustrated in FIG. 13. The plug extension 1212, which constitutes the body of the plug 1210, may provide an interference fit with the inside wall 1214 of the lamp holder 1204, or may be bonded to the inside wall 1214 in the various ways described herein.



FIG. 14 is an end view of another embodiment of a plug 1400. As shown in FIG. 14, plug 1400 is similar to plug 1210, with the exception that grooves 1408, 1410 are formed in the plug extension 1414 to accommodate three wires, i.e. wires 1402, 1404, 1406. The plug extension 1414 may have an interference fit with the inside wall 1412 of the lamp holder, or may be bonded to the inside wall 1412.



FIG. 15 is a schematic illustration of another embodiment for securing the plug 1504 to the lamp holder 1502. As shown in FIG. 15, barbs 1506 are formed on the exterior surface of the plug 1504. Engagement sockets 1508 are formed on the interior wall of the lamp holder 1502. The barbs 1506 on plug 1504 engage the engagement sockets 1508 on lamp holder 1502 to ensure that once the plug 1504 is inserted into the lamp holder 1502, the plug 1504 will be substantially inseparably connected to the lamp holder 1502.



FIG. 16 is a schematic illustration of another embodiment of an LED lamp assembly 1600. As shown in FIG. 16, lamp cover 1602 has an extended lamp base 1604. FIG. 16 does not include a lamp holder. As shown in FIG. 16, the LED lamp 1606 has an LED diode body 1608 that is attached to the interior wall 1616 of the lamp base 1604 using a bond or an interference fit, as described herein. Similarly, plug 1612 is attached to the inner wall 1616 of the lamp base 1604 using a bond or an interference fit 1614. The advantage of the device illustrated in FIG. 16 is that the LED lamp assembly 1600 is simple and uses fewer parts.


Hence, the various embodiments disclosed herein allow for the assembly of discrete components that are individually manufactured. The assembly process avoids damage to LED diodes and electric wires that can occur during overmolding in injection molding devices. The various embodiments illustrate a substantially inseparable LED lamp assembly that is formed on an LED light string that is resistant to theft and vandalism. The disclosed embodiments reduce manufacturing costs related to the high cost of special injection molding devices that are needed to accommodate LED lamps and LED lamp strings and eliminates the necessity for assembly at the site of the injection molder.
