Abstract
The utility model relates to a super-distant fiber coupling laser illuminator and belongs to the dynamo-electric field. The super-distant distance fiber coupling laser illuminator comprises a power source box and a lens which are connected, wherein one end of a circuit board is electrically connected with LD light emitting chips, and the other end of the circuit board is electrically connected with a power source. When the power source is switched on, a control signal is inputted into the circuit board, the circuit board controls the LD light emitting chips for light emitting, the seven LD light emitting chips are connected with a fiber, and laser beams emitted by the LD light emitting chips are emitted out after fiber coupling and then forms strong-brightness and uniform light spots after passing through a small eyeglass and a large eyeglass of a lens group. The super-distant distance fiber coupling laser illuminator is advantaged in that: the seven light emitting chips are utilized to emit the uniform light spots after fiber coupling; super-distant illumination is realized; an imported power source is utilized to realize large power and low power consumption; multiple fans are utilized to form a three-dimensional stereo circulation; the power source and the lens part are separate, and the super-distant fiber coupling laser illuminator further has properties of good heat radiation effect, simple and novel structure and strong practicality.
