Embodiment 1

[0074] Embodiment 1: The ABS used in the embodiment of the present invention is a terpolymer of acrylonitrile, butadiene and styrene, A represents acrylonitrile, B represents butadiene, and S represents styrene; wherein, acrylonitrile accounts for 25% ~30%, butadiene accounts for 16%~28%, and styrene accounts for 45%~60%.

[0075] The high thermal conductivity nanocomposite plastic of the present invention, the filler included in the preparation raw material is one or more of the following compounds (or mixtures): MgO, Al 2 o 3 、Si 3 N 4 , BN, high-purity carbon powder, AlN, ZnO, KAl(SO 4 ) 2 12H 2 O (alum), Al 2 o 3 -2SiO2 2 -2H 2 O (kaolin).

Embodiment 2

[0076] Embodiment 2: The MgO used in the embodiment of the present invention is nano MgO particles.

[0077] The industrial production process of nano powder materials requires simple preparation methods, suitable production costs, good repeatability, uniform powder particle size, high product purity and low agglomeration degree. There are many methods for synthesizing nano-magnesia in the prior art, but few of them can actually be applied to industrial production. One is because of problems such as equipment, cost, raw materials, scale, and investment; the other is that some processes are still in the laboratory research stage, and it is difficult to realize industrialized production, and some are even impossible to realize industrialized production.

[0078] In this example, MgO particles were prepared by a solid-phase method at room temperature.

[0079] The room-temperature solid-phase synthesis method of the present invention overcomes the agglomeration problem existing ...

Embodiment 3-1

[0081] Embodiment 3-1: Si used in the embodiment of the present invention 3 N 4 It is nano-silicon nitride particles and meets the following indicators:

Abstract

The invention discloses a light-emitting diode (LED) lamp. An LED lamp bead 1 is arranged on a stainless steel substrate 4, one face, provided with an LED lamp bead 5, of the stainless steel substrate 4 is connected with a protective shade 6, the other face of the stainless steel substrate is connected with a radiator 3, and a rotary joint type lamp opening 2 is fixedly connected with a rotary joint groove formed in a lamp seat through a rotary joint device arranged on the rotary joint type lamp opening. The radiator 3 is composed of cooling fins. An arc-shaped structure is adopted in the cooling fins and the cooling fins are evenly distributed. A light transmitting material quality structure is adopted in the protective shade 6. The protective shade 6 is in a semi-spherical shape. By the adoption of the rotary joint type structure in the LED lamp, the LED lamp can resolve the problem in an existing LED lamp, a production assembling method by manual matching of automatic installation and flow line assembly can be used, and the LED lamp has the advantages of being concise in production assembling, high in production efficiency, low in production cost, attractive and firm in connection, good in lighting effect, safe in use, and long in service life.

Description

technical field [0001] The invention relates to the technical field of lighting mechanical devices, in particular to a novel LED lamp and a preparation method thereof. Background technique [0002] The current LED lighting mostly adopts the method of filament connection, which has the problems of cumbersome production steps, long processing time for production parts, and high production cost. In addition, it also has poor thermal conductivity of materials, unsatisfactory stability, and molding, The problem of poor flame retardancy and insulation performance. Therefore, a LED lighting lamp that can solve the above problems is needed. The material can have good thermal conductivity and stability, and can well solve the problem of molding, flame retardancy and insulation Performance problems, while simplifying the assembly method, improving production efficiency, increasing production costs and service life, so as to meet the needs of actual conditions. [0003] Now, as electr...
