Abstract
Official abstract text for this publication.
The present invention relates to Light Emitting Diode (LED) devices featuring outstanding reflectivity and flame resistance. The LED according to the present invention comprises at least a part comprising a polymer composition (C) comprising at least one polymer (P) selected from the group consisting of a polyamide, a polyester, an epoxy and a silicon resin; a flame retardant and magnesium oxide.
First claim
Opening claim text (preview).
1 - 14 . (canceled) 15 . A part of a Light Emitting Diode device comprising a polymer composition (C) comprising: at least one polymer (P) selected from the group consisting of a polyamide, a polyester, an epoxy and a silicon resin; from 5 to 40 wt. %, based on the total weight of the composition (C), of a flame retardant system; and from 1 to 7 wt. %, based on the total weight of the composition (C), of magnesium oxide. 16 . The part according to claim 15 comprising from 3 to 5 wt. % of the magnesium oxide. 17 . The part according to claim 15 , wherein the polymer (P) is a polyamide. 18 . The part according to claim 17 , wherein the polyamide is a polyphthalamide. 19 . The part according to claim 15 , wherein the polymer (P) is a polyester. 20 . The part according to claim 19 , wherein the polyester is poly(cyclohexylenedimethylene terephthalate). 21 . The part according to claim 15 , wherein the polymer composition (C) further comprises at least a flame retardant synergist. 22 . The part according to claim 15 , wherein the polymer composition (C) further comprises at least one white pigment. 23 . The part according to claim 15 , wherein the polymer composition (C) further comprises at least one reinforcing filler. 24 . The part according to claim 23 , wherein the reinforcing filler is wollastonite, glass fibers, or mixtures thereof. 25 . The part according to claim 15 , wherein the flame retardant system comprises a halogenated flame retardant. 26 . The part according to claim 25 , wherein the halogenated flame retardant is a brominated compound/polymer. 27 . The part according to claim 15 , wherein the flame retardant system comprises a halogen free flame retardant. 28 . The part according to claim 27 , wherein the halogen free flame retardant comprises at least one organophosphorous compound selected from the group consisting of phosphinic salts (phosphinates), diphosphinic salts (diphosphinates), and condensation products thereof.
