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.

The main board includes a connector and a light source disposed beside the connector. The light guide heat dissipation module is detachably disposed on a position of the main board near the connector and is adapted to be thermally coupled to the expansion card inserted in the connector. The light guide heat dissipation module includes a first heat dissipation member, a second heat dissipation member thermally coupled to the first heat dissipation member, and a first light guide member disposed between the first heat dissipation member and the second heat dissipation member. The first heat dissipation member includes an opening, and the opening exposes a portion of the first light guide member. When the light guide heat dissipation module is disposed on the main board, light emitted by the light source is adapted to be guided by the first light guide member to the opening of the first heat dissipation member.
