The present invention relates to a lighting device including a light transmittable shell, a conductive unit and a light source. The light transmittable shell has an inner space and a mounting opening connected to the inner space. The light source is mounted around the mounting opening such that the LEDs in the light source are arranged along the edge of the mounting opening. The light from the light source transmits through the light transmittable shell from the edge of the mounting opening, leading to a glowing effect of the light transmittable shell, improving the lighting efficiency of the lighting device. Furthermore, the LEDs are distributed along the edge of the mounting opening and have direct contact with the flowing air in open space, so the heat-dissipation of the LEDs is effective enough without extra cooling components.

The light emitter is positioned adjacent the lens and configured to direct light in a direction generally orthogonal with respect to the central opening. The first reflector is positioned proximate a first surface of the lens distal the central opening. The first reflector substantially covers the first surface of the lens. The second reflector is positioned proximate a second surface of the lens opposite the first surface. The second reflector substantially covers the second surface of the lens outside of the central opening.
