Title:
HEAT DISSIPATING RESIN COMPOSITION FOR LED LIGHTING HOUSING AND HEAT DISSIPATING HOUSING FOR LED LIGHTING
Document Type and Number:
WIPO Patent Application WO/2011/125545
Kind Code:
A1
Abstract:
Disclosed are: a novel heat dissipating resin composition for an LED lighting housing, which exhibits excellent heat dissipation, flame retardancy, electrical insulation and moldability, while having low specific gravity and high degree of whiteness; and a heat dissipating housing for an LED lighting, which is obtained by molding the heat dissipating resin composition.
Specifically disclosed is a heat dissipating resin composition for an LED lighting housing, which is characterized by containing 5-200 parts by mass of an inorganic filler (Y), which is composed of 5-100% by mass of boron nitride (D) and 0-95% by mass of an inorganic oxide filler (E), per 100 parts by mass of a thermoplastic resin composition (X) that is composed of 40-65% by mass of a polyamide resin (A), 33.5-59.8% by mass of a metal hydroxide flame retardant (B) and 0.2-1.5% by mass of a polytetrafluoroethylene resin (C). The heat dissipating resin composition for an LED lighting housing is also characterized by having a thermal conductivity of not less than 1.0 W/m·K. Also specifically disclosed is a heat dissipating housing for an LED lighting, which is obtained by molding the heat dissipating resin composition.
