Abstract

This invention discloses a lighting device for omnidirectional light emission with efficient heat dissipation. In one embodiment, a lighting device comprises lighting modules circumferentially arranged such that generation of the omnidirectional light is allowable, and a supporting unit attached to each lighting module's heat-dissipating side for providing mechanical support. A space formed by minimally enclosing all the lighting modules includes a first polar opening, a second polar opening opposite thereto, and a ventilation channel between the two polar openings for enabling air flowing through the ventilation channel to carry away at least part of heat obtained from the heat-dissipating sides of the lighting modules to outside said space. A line-of-sight path between the two polar openings is identifiable, allowing a direct flow of air that advances through the ventilation channel between the two polar openings to be realizable, thereby promoting the carrying away of heat to outside said space.
