Abstract

The invention relates to a composition for an LED lamp holder. The composition comprises the following components by mass: 10 to 15 parts of graphite flake, 15 to 25 parts of zinc oxide, 8 to 15 parts of silica, 5 to 8 parts of modified corn starch, 2 to 6 parts of kaolin, 2 to 6 parts of dimethyl itaconate, 10 to 20 parts of modified purple sand powder, 2 to 6 parts of tea vinyl acetate, 4 to 8 parts of silicon carbide powder, 2 to 6 parts of Chinese medical stone powder, 2 to 6 parts of expanded graphite powder, 1 to 3 parts of boron nitride, 2 to 6 parts of sodium fluosilicate, 2 to 8 parts of lignin, 2 to 4 parts of wood plastic powder and 2 to 6 parts of cellulose. The components of the composition are simple; and through addition of the modified corn starch, the prepared lamp holder has good resistance to damp and corrosion, can bear high voltage without electric leakage and has excellent thermal diffusivity.

Description

technical field [0001] The invention relates to an LED lamp holder composition, which belongs to the technical field of LEDs. Background technique [0002] In the field of lighting, the application of LED light-emitting products is attracting the attention of the world. LED has many advantages such as high luminous efficiency, long service life, energy saving, environmental protection, etc., and is more and more widely used in many fields. Due to the low operating voltage of LED (only 1.5-3V), it can actively emit light and have a certain brightness, and the brightness can be adjusted by voltage (or current), and it is shock-resistant, anti-vibration, and long-life, so it has played a more and more important role in the display field. More and more applications, especially in the field of fluorescent lamps, have the technical advantages of high brightness and long life. In order to adapt to the development trend of energy saving and environmental protection, LEDs have been ...
