Problems solved by technology

[0002] At present, LED automotive lighting is widely used and has promising prospects, but the existing products have low power, low luminous efficiency, and short life.
The reason is that the heat dissipation problem is not solved well, which hinders the widespread application of LED lighting in the automotive field.
Existing products mainly use 6063 aluminum profiles and micro-fans to force heat dissipation, but vibration, noise and electromagnetic interference are generated, which seriously affect the on-board computer and electronic control system, and the shortcomings of the fan itself, such as power consumption and short life, reduce the efficiency of the lighting. Reliability brings security risks

Abstract

The invention discloses heat radiating paint for an LED automobile lamp and application of the heat radiating paint. The paint consists of 30-40wt% of small nanoscale boron nitride, 3-10wt% of nanoscale titanium oxide and 50-60wt% of thinner. During preparation, the thinner and boron nitride are uniformly mixed, and then, titanium oxide is added into the mixture and the obtained mixture is uniformly stirred. During application, the heat radiating paint coats the surface of a heat radiating body and is aired to be dry, roasted and cured to form a heat radiating coating. The heat conductivity ofthe surface of the heat radiating body coated with the heat radiating coating is larger than or equal to 1400W / (m*K), the heat radiating effect is remarkably improved, the oxidation resistance is improved, the cost of a lamp system is reduced, and the application range of an LED lamp in the field of automobiles is widened.
