Beschreibung
Zusammenfassung:	The present invention discloses a lighting apparatus, including a lamp body, an optical element connected with the lamp body, as well as a driving power source assembly, a light source assembly and a reflecting device configured to provide a secondary light distribution for the light source assembly which are received in the lamp body; the reflecting device is provided with a light inlet, a light outlet and a reflecting wall located between the light inlet and the light outlet; the reflecting wall is transparent, and includes an internal surface and an external surface; the internal surface includes a plurality of saw-tooth structures arranged continuously, each of the saw-tooth structures includes a first refracting surface and a second refracting surface intersected with each other, two ends of each of the saw-tooth structures extend towards the light inlet and the light outlet, respectively; and the light source assembly is disposed at the light inlet of the reflecting device. In the lighting apparatus of the present invention, the internal surface of the reflecting wall includes a plurality of saw-tooth structures arranged continuously, the internal surface is used as a light incident surface and a light emergent surface at the same time, and the external surface is used as a reflecting surface; with such design, all the light incident onto the internal surface can exit with an optical effect of total reflection, so as to improve the luminous efficiency without the need of an electroplating process.
