Title:
LIGHT SOURCE MODULE AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/077077
Kind Code:
A1
Abstract:
Light source modules (100, 100a, 100b) and a lighting device, comprising light source substrates (2, 2a, 2b), and further comprising several light-emitting units (3, 3a, 3b) provided on a surface of the light source substrates (2, 2a, 2b), drive power source assemblies (4, 4a, 4b) electrically connected to the light source substrates (2, 2a, 2b), and light distribution elements (1, 1a, 1b) detachably assembled onto the light source substrates (2, 2a, 2b) and the drive power source assemblies (4, 4a, 4b) respectively. The light distribution elements (1, 1a, 1b) comprise a drive accommodation portion and at least two light distribution portions (11b). The two light distribution portions (11b) cover the light source substrates (2, 2a, 2b) and distribute the light emitted from the light-emitting units (3, 3a, 3b). The cross-section types of the at least two light distribution portions (11b) are different, such that the emitted light passing through different light distribution portions (11b) has different beam angles, thereby allowing the light emitted from the light source modules (100, 100a, 100b) to reach a required range, and improving the flexibility of the lighting angle.
