Title:
ILLUMINATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/214390
Kind Code:
A1
Abstract:
An illuminating device (100a), comprising a lamp body (1a), an optical element (2a) connected to the lamp body (1a), a light source component (3a) accommodated in the lamp body (1a), a reflecting device (5a) for secondarily distributing light to the light source component (3a), and a driving power supply component (4a). The reflecting device (5a) is annular and transparent; the reflecting device (5a) has a light inlet (55a) and a light outlet (56a) at two ends of the reflecting device (5a); the reflecting device (5a) comprises an inner surface (51a) and an outer surface (52a); the outer surface (52a) comprises a plurality of continuously-arranged sawtooth structures (520a); each sawtooth structure (520a) comprises a first reflecting surface (521a) and a second reflecting surface (522a) intersecting each other; two ends of each sawtooth structure (520a) extend toward the light inlet (55a) and the light outlet (56a) respectively; the light source component (3a) is dispsoed at the light inlet (55a) of the reflecting device (5a). The reflecting device (5a) in the illuminating device (100a) uses a lens as a reflecting wall (50a) and uses the outer surface (52a) having the plurality of continuously-arranged sawtooth structures (520a) as a reflecting surface, so that light incident through the inner surface (51a) can exit by means of a total-reflection optical effect, and the light exit efficiency is improved without needing electroplating treatment.
