  • Vaccum plating

    At one time, many device components were made of metal for electromagnetic interference (EMI) protection, but the move to plastic offers a suitable alternative. To overcome the biggest weakness of plastic in attenuating electromagnetic interference, the lack of electrical conductivity, engineers ...

  • The material of the reflector

    Normally, the light energy from the light source will radiate in a 360° direction. In order to effectively utilize the limited light energy, the lamp can control the illumination distance and illumination area of the main light spot through the light reflector. Reflective cup is a reflector that ...
