Abstract
Official abstract text for this publication.
A method for manufacturing a carrier and a carrier for an optoelectronic unit are disclosed. In various embodiments the carrier has a carrier material which includes polyethylene terephthalate which contains reflector particles and a filler.
First claim
Opening claim text (preview).
What is claimed is: 1 . A carrier for an optoelectronic unit comprising: a carrier material comprising polyethylene terephthalate that contains reflector particles and a filler, wherein the filler comprises glass fibers. 2 . The carrier according to claim 1 , wherein the carrier material further contains a cross-linking additive that is at least partially cross-linked with the polyethylene terephthalate, wherein the cross-linking additive is tetraallyl isocyanurate and has a proportion of greater than or equal to 2 wt. % and less than or equal to 4 wt. % of the carrier material. 3 . The carrier according to claim 1 , wherein the reflector particles comprise at least one or more of the following materials: titanium oxide, zinc oxide, zirconium oxide and barium sulphate. 4 . The carrier according to claim 1 , wherein the carrier material comprises polybutylene terephthalate in a proportion of less than or equal to 60 wt. %. 5 . The carrier according to claim 1 , wherein the carrier material comprises polybutylene terephthalate in a proportion of less than or equal to 20 wt. %. 6 . The carrier according to claim 1 , wherein the carrier material comprises polybutylene terephthalate in a proportion of less than or equal to 10 wt. %. 7 . The carrier according to claim 1 , wherein the reflector particles have an achromatic inorganic pigment with a high refraction index of greater than or equal to 1.7. 8 . The carrier according to claim 1 , wherein the glass fibers have an average length of 200 to 400 μm and an average diameter of 6 to 15 μm. 9 . A carrier for an optoelectronic unit comprising: a carrier material comprising polyethylene terephthalate that contains reflector particles and a filler, wherein the carrier material comprises polybutylene terephthalate in a proportion of less than or equal to 60 wt. %. 10 . The carrier according to claim 9 , wherein the carrier material further comprises a cross-linking additive that is at least partially cross-linked with the polyethylene terephthalate, wherein the cross-linking additive is tetraallyl isocyanurate and has a proportion of greater than or equal to 2 wt. % and less than or equal to 4 wt. % of the carrier material. 11 . The carrier according to claim 9 , wherein the reflector particles comprise at least one or more of the following materials: titanium oxide, zinc oxide, zirconium oxide, and barium sulphate. 12 . The carrier according to claim 9 , wherein the carrier material comprises polybutylene terephthalate in a proportion of less than or equal to 20 wt. % of the carrier material. 13 . The carrier according to claim 9 , wherein the carrier material comprises polybutylene terephthalate in a proportion of less than or equal to 10 wt. %. 14 . The carrier according to claim 9 , wherein the reflector particles have an achromatic inorganic pigment with a high refraction index of preferably greater than or equal to 1.7.
