I claim:
1. A method of fabricating a PVC ornamental article having effects of imitated materials comprising steps of:
(a) mold casting: making a prototype of a desired ornamental article, exploding said prototype into a plurality of blank elements, coating said blank elements with silicone to form hollow silicone molds, injecting a wax material into said hollow silicone molds to obtain a wax object, taking out said wax object for trimming and electroplating said wax object, and melting said wax object to obtain a mold;
(b) blank formation: adding colorants into PVC plastic material and mixing said colorants to obtain desired colors, injecting said PVC plastic material into said mold, utilizing centrifugal force to affix said PVC plastic material onto an inner wall of said mold, and removing molded PVC from said mold to form a blank by force before said molded PVC dries, filling a filler into said blank to increase hardness; and
(c) assembly: assembling blanks together and joining the blanks with other decorations to obtain a PVC ornamental article.
2. The method of claim 1, wherein material for said electroplating is copper.
3. The method of claim 1, wherein the copper mold is mounted onto a molding plate.
4. The method of claim 1, wherein the added colorants are selected from the group consisting of colors of stone material, wooden material, glass, ceramics, resins material, pulp, fabric material and cast iron, etc.
5. The method of claim 1, wherein the filler is a foaming agent.
6. The method of claim 1, wherein the filler is compressible and has a hardness like wood.
7. The method of claim 1, wherein at least one support body is provided to the filler at the time filling, depending on the length of the article, so that said at least one support body may form a tensile force between the blanks.
8. The method of claim 7, wherein the support is a wooden bar or an iron bar.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A thermal management system for a display case having a corner, comprising:
a lighting system support positioned in the corner of the display case;
a lighting system comprising a reflector and a heat-generating light source, wherein the heat-generating light source is mounted with the reflector, and wherein the lighting system is associated with the lighting system support;
a mullion positioned between the lighting system support and the lighting system, the mullion to maintain a desired relative position between the lighting system support and the lighting system; and
a contactor between the lighting system support and the lighting system, wherein the contactor provides minimal thermal conduction between the lighting system support and the lighting system whereby heat transfer from the heat-generating light source to the lighting system support is reduced, thereby reducing an amount of heat transferred to the corner of the display case.
2. The thermal management system of claim 1, wherein the lighting system comprises a first system side, wherein the lighting system support comprises a first support side, and wherein the first system side is at least partially co-extensive with the first support side.
3. The thermal management system of claim 2, wherein the contactor comprises a plurality of spaced apart projections located between at least the first system side and the first support side.
4. The thermal management system of claim 3, wherein the lighting system comprises a base and wherein the lighting system support comprises a second support side.
5. The thermal management system of claim 4, wherein the plurality of spaced apart projections is located between the base and the second support side.
6. The thermal management system of claim 3, wherein a subset of the plurality of spaced apart projections are conical.
7. The thermal management system of claim 1, wherein the lighting system comprises a base, wherein the lighting system support comprises a first support side and a second support side, and wherein the contactor comprises a non-metallic, heat-insulating member positioned between the base and the second support side.
8. The thermal management system of claim 7, wherein the non-metallic, heat-insulating member comprises a depending arm positioned between the first support side and the lighting system.
9. The thermal management system of claim 8, wherein the lighting system comprises a first system side, and wherein the depending arm is positioned between the first support side and the first system side.
10. The thermal management system of claim 1, wherein the heat-generating light source comprises at least one solid state light source.
11. The thermal management system of claim 10, wherein the lighting system comprises a luminaire including the at least one solid state light source.
12. A thermal management system for a display case having a corner, comprising:
a lighting system support positioned in the corner of the display case;
a lighting system comprising a reflector and a heat-generating light source, wherein the heat-generating light source is mounted with the reflector, and wherein the lighting system is associated with the lighting system support; and
at least one mullion positioned between the lighting system support and the lighting system, wherein the at least one mullion is substantially thermally insulating, the mullion to maintain a desired relative position between the lighting system support and the lighting system and to reduce heat transfer from the heat-generating light source to the lighting system support, thereby reducing an amount of heat transferred to the corner of the display case.
13. The thermal management system of claim 12, wherein the at least one mullion comprises a plurality of spaced-apart mullions, wherein a subset of the plurality of spaced-apart mullions are thermally insulating.
14. The thermal management system of claim 13, wherein the lighting system comprises a first system side, wherein the lighting system support comprises a first support side, and wherein the first system side is at least partially co-extensive with the first support side.
15. The thermal management system of claim 14, wherein the plurality of spaced apart mullions is located between at least the first system side and the first support side.
16. A thermal management system for a display case having a corner, comprising:
a lighting system support positioned in the corner of the display case, comprising a first support side;
a lighting system comprising a reflector and a heat-generating light source, wherein the heat-generating light source comprises at least one temperature-dependent solid state light source, wherein the at least one temperature-dependent solid state light source is mounted with the reflector, wherein the lighting system is associated with the lighting system support, and wherein the lighting system includes a first system side that is at least partially co-extensive with the first support side;
a mullion positioned between the lighting system support and the lighting system, the mullion to maintain a desired relative position between the lighting system support and the lighting system; and
a contactor between the first system side of the lighting system and the first support side of the lighting system support, wherein the contactor provides minimal thermal conduction between the lighting system support and the lighting system whereby heat transfer from the at least one temperature-dependent solid state light source to the lighting system support is reduced, thereby reducing an amount of heat transferred to the corner of the display case.
