Abstract

A downlight apparatus includes a light source, a driver box, a light housing and a heat dissipation plate. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The heat dissipation plate is placed between the light holder and the driver box for carrying away both heat of the driver box and the light source. The heat dissipation plate is a separate metal piece from the driver box and the light housing. The heat dissipation plate has a portion not covered by the light holder and the driver box and exposed to air.
