Abstract

The invention discloses a high-lumen maintenance organosilicon material for LED packaging. The organosilicon material comprises a silicone component A, a silicone component B, nanometer magnesium oxide, a phosphor and an acrylic polymer, wherein the silicone component A comprises 60-85 parts of vinyl-terminated polymethylphenylsiloxane, 5-15 parts of vinyl-terminated polydimethylsiloxane, 3-8 parts of an active organic borosilicate tackifier, 10-25 parts of vinyl-terminated hyperbranched silicone resin and 0.05-0.5 part of a platinum catalyst; the silicone component B comprises 35-45 parts ofvinyl-terminated polymethylphenylvinylsiloxane, 45-55 parts of polymethylhydrosiloxane, 5-15 parts of MQ resin and 3-8 parts of a silane coupling agent A-172; and a mass part ratio of the silicone component A to the silicone component B to the nanometer magnesium oxide to the phosphor to the acrylic polymer in the organosilicon material is 100:100:(2.5-18):(3-8):(1-3). The organosilicon material has advantages of resistance to environmental hot and cold alternation, non-yellowing and high luminous flux.

Description

technical field [0001] The invention relates to an LED encapsulation material, in particular to an organic silicon material for LED encapsulation with high lumen maintenance rate. Background technique [0002] LED is a light-emitting diode, which is a high-efficiency solid light source, which has the advantages of energy saving and environmental protection, and has a relatively long service life. At present, LED has been widely used in people's daily life and work. Its application principle is to irradiate fluorescent substances with blue light LED to produce yellow light complementary to blue light, and then to obtain white light. [0003] The Energy Star standard requires that the 25,000-hour lifespan LED lamp requires a luminous flux maintenance rate of 91.8% at 6,000 hours, and if the lamp type is a directional lamp, the maximum test ambient temperature is 55°C±5°C, which is quite high. standard requirements. [0004] For example, a kind of LED filament packaging mater...
