A method of making a subassembly () for a PAR lamp () comprising the steps of: (a) providing a base () including a cup-shaped portion () with a top edge () having an extended flange () projecting therefrom; (b) providing a plurality of electrical contacts () and inserting the contacts into appropriate locations () in a bottom () of the cup-shaped portion (); (c) providing a lamp capsule () including a light source () having dependent leads () projecting from a base end (); (d) inserting the base end () of the lamp capsule () into the cup-shaped portion () and affixing the dependent leads () to the electrical contacts (); (e) providing a reflector () having a funnel-shaped body () with a substantially tubular neck (); (f) filling the cup-shaped portion () with a liquid cement () to a depth that covers the base end () of the lamp capsule (); (g) fitting the reflector () over the lamp capsule () so that the tubular neck () is submersed in the liquid cement (); and (h) heating the subassembly () to fix the reflector () in place.

PAR lamp and method of making same

An integrally ballasted lamp assembly () including a spacer disk () disposed in a lamp receptacle cavity () between a lamp () and the bottom () of the lamp receptacle (). The disk () may be configured to contact connector clips () coupled to the bottom () of the lamp receptacle to positively align the clips () for connection to a ballast circuit disposed on a PCB (). The disk () may also, or alternatively, at least partially occlude connector clip openings () in the bottom () of the lamp receptacle () for hindering the flow of uncured cement () through the openings (), and may also, or alternatively, provide a thermal barrier between the lamp () and the lamp receptacle ().

Integrally ballasted lamp assembly including a spacer disk

An integral HID reflector lamp may be formed with an HID held in a reflector. An inner element is mechanically coupled to the reflector. The inner element is formed with a first mechanical coupling to mate with the reflector, a second mechanical coupling to mate with a circuit board, and an electrical coupling to at least electrically couple one of the leads to the circuit board. A circuit board has an edge mechanically coupled to the inner element and electrically connected to the leads by an electrical coupling on the inner element. A heat sink spans at least one side of the circuit board and forming an EMI shielding. An outer cover encloses the heat sink, circuit board, and inner element and coupled to the assembly of the reflector, HID lamp, inner element, and heat sink with each elements of the assembly clipped together.
