Embodiment 1
[0073] 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%.
[0074] The nano high thermal conductivity composite 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, CuO, KAl(SO 4 ) 2 12H 2 O (alum), Al 2 o 3 -2SiO2 2 -2H 2 O (kaolin).
Embodiment 2
[0075] Embodiment 2: The MgO used in the embodiment of the present invention is nano MgO particles.
[0076] 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.
[0077] In this example, MgO particles were prepared by a solid-phase method at room temperature.
[0078] The room-temperature solid-phase synthesis method of the present invention overcomes the agglomeration problem existing ...
Embodiment 3-1
[0080] Embodiment 3-1: Si used in the embodiment of the present invention 3 N4 It is nano-silicon nitride particles and meets the following indicators:

Abstract
The invention discloses a light-emitting diode (LED) lamp bulb which comprises a lamp holder, a radiator, an aluminum substrate, LED lamp beads and a protective cover. The LED lamp bulb is further provided with a bayonet lamp socket. The lamp holder is connected with the radiator through the bayonet lamp socket. The LED lamp beads are arranged on the aluminum substrate. The aluminum substrate is provided with the LED lamp beads, one face of the aluminum substrate is connected with the protective cover, and the other face of the aluminum substrate is connected with the radiator. The bayonet lamp socket is fixedly connected with a bayonet groove arranged on the lamp holder through a bayonet arranged on the bayonet lamp socket. The LED lamp bulb adopts a bayonet type structure, can solve the problems of existing LED illuminating lamps and adopt a production assembly mode that automatic installation and production line assembly mutual matched usage are combined, and has the advantages of being simple in production assembly, high in production efficiency, low in production cost, firm in connection, attractive, good in illuminating 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 light bulb and its preparation and installation method. 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. [000...
