The utility model discloses a lighting device, it includes at least one luminous semiconductor component, load bearing seat and lamp shade, should set up on the load bearing seat by luminous semiconductor component, and the lamp shade sets up on the load bearing seat and covers the luminous semiconductor component, the lamp shade includes first light-emitting portion, encircles the side light-emitting portion of first light-emitting portion, and the micro-structure, this micro-structure sets up in one side of first light-emitting portion and in the face of luminous semiconductor component to a light for reflecting should launch by luminous semiconductor component. The utility model discloses a lighting device includes a plurality of micro-structures for increase the reflection angle of the light of luminous semiconductor component transmission, these a plurality of micro-structures set up with downward light beam on this first plain noodles to obtain more the play light distribution of wide angle or omnirange, and the shape of this micro-structure, size and arrangement have optimized so that illuminance is better, that is to say, can promote this lighting device's illuminance and improve a light distribution.
