Universal lamp support
View Patent ↗An illumination apparatus includes a monolithic support substrate and light emitting diodes (LEDs) on one or more external sides of the support substrate. The support substrate may comprise an elongated extrusion enclosing a hollow core. The LEDs may be affixed to rigid or flexible electrical substrates. Each electrical substrate may be affixed to an external side of the extrusion and may include embedded LED circuitry. The hollow core may enable the extrusion to be received in a recessed socket of a light fixture, wherein the recessed socket provides structural support for the applicable end of the extrusion, rendering end caps or end socket adapters unnecessary. The light fixture may include a contact protruding from the recessed socket and the electrical substrates may include circuitry configured to couple the LEDs to a source of power not coupled to the protruding contact.
1. A lamp apparatus, comprising:
a monolithic support including an end configured to receive a protruding contact protruding from a recessed lamp socket; and
one or more light emitting diode (LED) strings, affixed to the monolithic support, wherein each of the one or more LED strings includes:
one or more LEDs; and
circuitry configured to couple the one or more LEDs to a power source not electrically coupled to the protruding contact.
2. The lamp apparatus of claim 1 , wherein one or more of the one or more LED strings includes an LED housing the monolithic support.
3. The lamp apparatus of claim 2 , wherein one or more of the one or more LEDs includes a lens.
4. The lamp apparatus of claim 1 , wherein the end of the monolithic support defines an opening configured to receive the protruding contact.
5. The lamp apparatus of claim 1 , wherein the monolithic support comprises an extruded monolithic support.
6. The lamp apparatus of claim 5 , wherein the extruded monolithic support defines a hollow core.
7. The lamp apparatus of claim 6 , wherein the extruded monolithic support includes a plurality of external surfaces.
8. The lamp apparatus of claim 7 , wherein one or more of the one or more LEDs strings are affixed to one or more of the plurality of external surfaces.
9. The lamp apparatus of claim 7 , wherein the monolithic support includes four external surfaces.
10. The lamp apparatus of claim 9 , wherein the monolithic support has a substantially square or rectangular cross section.
11. The lamp apparatus of claim 1 , further comprising:
a heat shrunk transparent sleeve affixing one or more of the one or more LED strings to the monolithic support.
12. The lamp apparatus of claim 11 , further comprising a sealant applied at one or both ends of the heat shrunk transparent sleeve.
13. The lamp apparatus of claim 1 , further comprising:
an adhesive to adhere one or more of the one or more LED light strings to the monolithic support.
14. The lamp apparatus of claim 1 , further comprising:
one or more mechanical fasteners fastening one or more of the one or more LED light strings to the monolithic support.
15. The lamp apparatus of claim 1 , wherein at least a portion of at least one of the one or more LED strings is encapsulated by an encapsulant.
16. The lamp apparatus of claim 15 , wherein the encapsulant comprises a transparent and water resistant encapsulant.
17. A lighting apparatus, comprising:
an elongated monolithic support including an end configured to receive a protruding contact protruding from a recessed lamp socket, wherein the protruding contact received in the end of the elongated monolithic support provides mechanical support for the monolithic support; and
one or more light emitting diode (LED) strings, affixed to the elongated monolithic support, wherein each of the one or more LED strings includes:
one or more LED substrates;
one or more LEDs mounted on each of the one or more LED substrates; and
power source circuitry configured to couple the LED string to an independent source of power for powering each of the one or more LEDs, wherein the independent source of power is not electrically coupled to the protruding contact.
18. The lighting apparatus of claim 17 , wherein at least one of the one or more LED includes a moisture barrier to protect the one or more LEDs from moisture.
19. The lighting apparatus of claim 17 , wherein at least one of the one or more LED strings is encased within a transparent substrate providing a barrier between the one or more LEDs and environmental moisture.
20. The lamp apparatus of claim 17 , wherein cross sectional dimensions of a body portion of the elongated monolithic support are substantially the same as cross sectional dimensions of the end of the elongated monolithic support.
