The lighting apparatus has a wire box, a driver module, a light source and a light housing. The wire box is made of a heat dissipation material. The wire box is for placing a portion of an external wire. The driver module electrically connects to an electrode of the portion of the external wire. The light housing has a top cover and a surrounding wall. The top cover and the surrounding wall form a container space. The top cover has an inner side and an exterior side. The light source is thermally and structurally connected to the inner side for emitting a light via a light opening of the container space. The wire box is connected to the top cover of the light housing. Heat of the light source is transmitted to the wire box for heat dissipation via the back cover.
