Abstract: A lighting device (10) comprises: a housing (1), a light source (7), a DMD chip (8), a lens assembly (9), and a light absorbing member (91). The light source (7) and the DMD chip (8) are separately disposed within the housing (1). The DMD chip (8) has an on state and an off state. The lens assembly (9) is disposed at the housing (1). Light generated by the light source (7) passes through the DMD chip (8) and is emitted from the lens assembly (9). When the DMD chip (8) is in the on state, an emergent light path is provided between the DMD chip (8) and the lens assembly (9). The light absorbing member (91) is offset in respect to the emergent light path, and is used to absorb light reflected by the DMD chip (8) when the DMD chip (8) is in the off state. In this way, the DMD chip (8) cooperates with the light absorbing member (91), such that the light absorbing member (91) is capable of absorbing light reflected by the DMD chip (8) when the DMD chip (8) is in the off state, thereby preventing the light reflected by the DMD chip (8) from being emitted from the lighting device (10). The invention ensures that usability of the lighting device (10) is not affected, and enables the light absorbing member (91) to be on a light absorbing line, so as to reduce the overall size of the lighting device.
