Title:
ILLUMINATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/214391
Kind Code:
A1
Abstract:
An illuminating device (100b), comprising a lamp body (1b), an optical element (2b) connected to the lamp body (1b), a driving power supply component (4b) accommodated in the lamp body (1b), a light source component (3b), and a reflecting device (5b) used for secondarily distributing light to the light source component (3b). The reflecting device (5b) has a light inlet (55b), a light outlet (56b), and a reflecting wall (50b) located between the light inlet (55b) and the light outlet (56b); the reflecting wall (50b) is transparent and comprises an inner surface (51b) and an outer surface (52b); the inner surface (51b) comprises a plurality of continuously-arranged sawtooth structures (510b); each sawtooth structure (510b) comprises a first refracting surface (511b) and a second refracting surface (512b) intersecting each other; two ends of each sawtooth structure (510b) extend toward the light inlet (55b) and the light outlet (56b) respectively; the light source component (3b) is disposed at the light inlet (55b) of the reflecting device (5b). The inner surface (51b) of the reflecting wall (50b) of the illuminating device (100b) comprises the plurality of continuously-arranged sawtooth structures (510b), the inner surface (51b) serves as a light incident surface and a light exit surface at the same time, and the outer surface (52b) serves as a reflecting surface. By means of such a design, light incident through the inner surface (51b) can exit by means of a total-reflection optical effect, and the light exit efficiency is improved without needing electroplating treatment.
