Abstract

A lighting module (10) is disclosed, comprising a first carrier substrate (1) and lighting units (2, 4a-4d). The first carrier substrate (1) is bendable. The first carrier substrate (1) is bent so as to form a tubular structure (5), which is elongate and possibly at least partially hollow, and has a central longitudinal axis (LA). At least part of one side of the first carrier substrate (1) at least partially constitutes the outer surface (6) of the tubular structure (5) exhibiting a plurality of surface portions (6a-6d), wherein the plurality of surface portions (6a-6d) ) are configured such that at least some of the surface portions (6a-6d) each have a surface normal at an angle with respect to a plane perpendicular to the central longitudinal axis (LA) and passing through the corresponding surface portion (6a-6d) (7a, 7d). A lighting unit (2, 4a-4d) is coupled to at least a part of one side of the first carrier substrate (1). Through the geometrical configuration of the plurality of surface parts (6a-6d), the lighting unit (2, 4a-4d) and possibly at least one light-emitting element (4a-4d) included therein can have a main direction of light emission that The main direction of emission is angled relative to a plane passing through the tubular structure (5) and substantially perpendicular to the central longitudinal axis (LA) of the tubular structure (5).

Description

technical field [0001] The present invention generally relates to the field of lighting equipment and lighting devices. In particular, the present invention relates to a lighting module for use in a lighting device and a lighting device including the lighting module. Background technique [0002] The use of light emitting diodes (LEDs) for lighting purposes continues to attract attention. LEDs offer many advantages over incandescent lamps, fluorescent lamps, neon tube lamps, etc., such as longer operating life, reduced power consumption, increased efficiency related to the ratio of light energy to thermal energy, and the like. Solid state-based light sources, such as LED-based light sources, may have different optical properties compared to incandescent light sources. In particular, solid-state based light sources can provide a more directional light distribution and a higher (ie, cooler) color temperature than incandescent light sources. Accordingly, efforts have been ma...
