Low profile extrusion
View Patent ↗The present invention provides various embodiments for apparatuses and methods of manufacturing low profile housings for electronic and/or optoelectronic devices. Some embodiments provide low profile housings with a hollow casing comprising a first surface, second surface, and at least one lateral side surface. The housing is substantially light-diffusive. At least one cap is provided for sealing an end of the casing, with the at least one cap being sized to account for variations in the casing. At least one light emitting device, such as an LED, may be mounted within the casing. A mounting means may be included for mounting the housing to a mounting surface.
1. A low profile housing comprising:
a first hollow casing comprising a first surface, a second surface substantially opposite said first surface, and at least one lateral side surface, wherein said casing is substantially light diffusive;
at least one end cap for sealing an end of said casing, wherein said at least one end cap is sized to account for variations in said casing; and
one or more electronic devices mounted within said casing, wherein said one or more devices abut at least said first surface.
2. The low profile housing of claim 1 , further comprising a secondary hollow casing co-extruded with said first casing, said secondary casing substantially surrounding all but said second surface of said first casing.
3. The low profile housing of claim 1 , further comprising a mounting means for mounting said housing to an external surface.
4. The low profile housing of claim 1 , wherein said at least one end cap is bonded to said casing using an adhesive.
5. The low profile housing of claim 1 , wherein said one or more devices comprises a single-sided, cut table printed circuit board with a plurality of light emitting diodes, such that light from said diodes may be emitted through said second surface and appear as one continuous light source.
6. The low profile housing of claim 1 , wherein at least a portion of said second surface is substantially smooth and free from extrusion lines and tooling marks on its internal and external surfaces.
7. The low profile housing of claim 1 , wherein said casing comprises acrylic.
8. The low profile housing of claim 1 , wherein said at least one end cap comprises a substantially flexible and waterproof material.
9. The low profile housing of claim 1 , wherein said housing is completely sealed to prevent exposure to external contaminants.
10. The low profile housing of claim 1 , wherein said at least one end cap comprises a through-hole for receiving a power cable, wherein the diameter of said through-hole is slightly smaller than the diameter of said cable.
11. A low profile housing comprising:
a first elongated hollow casing comprising a top surface and a bottom surface, wherein said casing is substantially light diffusive;
a second elongated and substantially hollow casing surrounding all but said top surface of said first casing;
at least one end cap for sealing an end of said first casing; and
one or more light emitting devices mounted within said first casing.
12. The low profile housing of claim 11 , wherein said first and second casing are co-extruded with one another.
13. The low profile housing of claim 11 , wherein said at least one end cap is a silicone plug adapted to prevent external contaminants from entering said first casing.
14. The low profile housing of claim 11 , wherein said one or more devices comprise a single-sided printed circuit board with a plurality of light emitting diodes, such that light from said diodes may be emitted through said top and/or bottom surface and appear as one continuous light source.
15. The low profile housing of claim 11 , wherein said one or more devices comprise a single- or double-sided printed circuit board that is cuttable along its length.
16. The low profile housing of claim 11 , wherein said second casing comprises at least one end cap, wherein said end cap is sized to account for variations in said second casing.
17. The low profile housing of claim 11 , wherein said first casing comprises acrylic.
18. The low profile housing of claim 11 , wherein said second casing comprises a transparent colored plastic.
19. A method for use in manufacturing a low profile housing, comprising:
extruding a hollow, light-diffusive, first casing comprising a first surface and a second surface substantially opposite said first surface, wherein said first and second surface are substantially free of from extrusion lines and tooling marks;
positioning at least one electronic and/or optoelectronic device within said casing; and
securing as least one end cap on at least one end of said first casing such that said casing is sealed.
20. The method of claim 19 , further comprising:
Co-extruding a substantially hollow second casing with said first casing, with said second casing surrounding all but said second surface of said first casing; and
Mounting said housing such that said second surface of said first casing abuts an external surface.
21. A low profile housing comprising:
a first casing comprising a bottom surface, a top surface, at least one side surface, and a plurality of external curved extensions;
a second casing comprising a bottom surface, a top surface, and at least one side surface, wherein said top surfaces of each of said casings are integral; and
wherein said first casing at least partially surrounds said second casing.
22. The housing of claim 21 wherein said first casing and said second casing are co-extruded with one another.
23. The housing of claim 21 wherein said first casing and said second casing are fitted together.
24. The housing of claim 21 wherein said at least one side surface of said second casing is angled.
25. The housing of claim 21 wherein said second casing is substantially clear.
26. The housing of claim 21 wherein said second casing is comprised of a frosted material.
27. The housing of claim 21 wherein said second casing is comprised of a light diffusive material.
28. The housing of claim 21 wherein said second casing is comprised of a material which at least partially contains light diffusants.
29. The housing of claim 21 wherein said first casing is comprised of a colored material.
30. The housing of claim 21 wherein said first casing is comprised of a light permeable material.
31. The housing of claim 21 further comprising a mounting bracket, wherein said mounting bracket comprises a base portion with a flange for securing said mounting bracket to said first casing such that said flange is capable of fitting under said external curved extensions.
32. The housing of claim 21 wherein said second casing can accommodate one or more electronic devices.
33. A lighting system, comprising:
an elongated housing that is substantially light transmissive and comprises a first cross-sectional portion that is clear, and a second cross-sectional portion that is colored, said housing also comprising elongated casing for holding a solid state light source, said housing arranged to emit light of different colors in opposing directions.
