A lighting device includes a housing, and a light-emitting module mounted in an accommodation chamber inside the housing and carrying a set of light-emitting devices on a circuit board thereof for emitting light, a plurality of refracting prisms for refracting a part of the light emitted by the light-emitting devices horizontally toward two opposing sides through the light transmissive peripheral wall of the top cover shell of the housing and two opposing double-beveled reflectors for reflecting the other part of the light emitted by the light-emitting devices toward the outside through the light transmissive peripheral wall of the top cover shell of the housing in the same opposing directions. Thus, the invention extends the luminous range of the light-emitting devices, enhances the luminance and reduces light loss.
