Abstract

A downlight apparatus includes a driver box, a light source, a light housing, multiple leaf springs, multiple shaft connectors and multiple pads. The light housing has a light holder and a rim. The light holder has a holder plate and a holder wall defining a holder cavity. The multiple leaf springs are placed between the driver box and the light holder. Each pad has a pad hole and a pad scraper surrounding the pad hole. The pad scraper has a protruding part engaging an electric insulation layer on a top side of the holder plate. The shaft connector sequentially passes through a spring hole of the leaf spring, the pad hole and the top plate of the light holder. The protruding part of the pad scraper scraps a portion of the electric insulation layer of the holder plate for connecting the holder plate to ground.
