Abstract
The invention relates to a lighting system of a handheld slit lamp. The lighting system of the handheld slit lamp comprises a slit light source, a projecting mirror and a reflecting prism which are sequentially arranged in the direction of lighting light rays and located on a same optical axis. The projecting mirror can move along the optical axis relative to the slit light source which can rotate around the optical axis, and silt light beams emitted from the silt light source form silt light zones in an upright state or a horizontal state or an inclined state after passing through the projecting mirror and the reflecting prism. A rotating device is additionally arranged in an imaging system of the light beams of a lighting assembly, so that the upright or horizontal or inclined silt light zones can be generated at the positions to be detected of eyes, change of sizes and position states of the slit light zones is achieved in a mode that the same mobile rotating device axially moves and rotates around the optical axis, so that the lighting system of the handheld slit lamp is reliable in working, compact in structure and flexible and convenient to adjust.
