Title:
LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/062718
Kind Code:
A1
Abstract:
A lighting device (100') comprises a lamp body (1'), a light-source module arranged in the lamp body (1'), and a translucent element (41') covering the light-source module. The light-source module comprises a plurality of lenses (3') and a light-emitting unit (2') disposed in each of said lenses (3'); the light emitted by the light-emitting units (2') is emitted through the translucent element (41') after passing through and being distributed by the lenses (3'). The translucent element (41') is arc-shaped, such that the angle of incidence corresponding to the incident light at any point on the translucent element (41') is less than 45 degrees, which reduces the reflectivity of the translucent element (41') with respect to incident light, and causes only slight change to light distribution as light passes through the translucent element (41'), thus increasing the light distribution effectiveness of the lighting device.
