Lamp accessories are various parts and accessories used to install, secure and connect lighting fixture. They play an important role, not only to ensure the normal operation of the lamp, but also to improve the use effect and aesthetics of the light.
There are many materials for making lamp accessories, generally speaking, there are metal, plastic, glass, ceramics, etc. Metal generally has a long service life, corrosion resistance, and should not be aged, such as iron product lamps, which have a long service life; Plastic lighting product have a short use time, a faster aging speed, and are easy to deform when heated; The service life of glass and ceramic lighting is long as well.
Nowadays, the lighting and lighting accessories industry uses metal materials as the most widely used base, generally used materials are zinc alloy, aluminum alloy, steel, stainless steel, etc. The use of technology is mainly electroplating, painting, oxidation and electrophoretic coating. With the current people to lighting accessories product performance requirements and environmental awareness improved, electrophoretic coating process has gradually become the preferred process for surface treatment of lighting accessories.

Graphite and diamond are allomorphs composed of carbon elements, and their interatomic structures are quite different. Synthetic diamonds have higher atomic densities than natural diamonds.
Researchers from institutions such as Hyogo University of Education and Tokyo Institute of Technology used neutron ray to irradiate graphite in an experimental reactor, followed by impacting graphite with a metal sheet moving at a speed of 1.7 km per second, and then applying high temperature and high pressure to the graphite. . After this series of "destruction", graphite will break into particles, and its maximum size is only 100 microns. The researchers used light to illuminate and analyze the particles, and found that the crystal particles were randomly arranged and oriented differently, forming a synthetic diamond whose crystal particles were small enough to reach the limit.
Japan uses graphite to synthesize crystal particles with tiny artificial diamonds
Xinhua News Agency, a research group in Japan published a paper in the March 20th issue of the American Physical Review Newsletter, saying that they synthesized synthetic diamond with graphite. Because the size of the crystal particles has shrunk to the limit, theoretically speaking, The hardness of this substance is extremely high.
