Wide-spectrum LED light source

The utility model discloses a wide spectrum LED light source which comprises a shell, a circuit board and an LED lamp panel are arranged in the shell, a plurality of LED lamp beads are arranged on the LED lamp panel, light emitted by the LED lamp beads is focused to an optical fiber interface through a Fresnel lens, a shutter assembly is arranged between the Fresnel lens and the optical fiber interface, and the shutter assembly and the LED lamp panel are electrically connected with the circuit board. Cooling fins are arranged on the face, away from the LED lamp beads, of the LED lamp panel, and a cooling fan is arranged on the shell. The high-stability LED lamp beads are used, the defect that a single LED light source is narrow in spectrum is overcome through integration of the lamp beads, and the LED lamp has the advantages of being low in power consumption, wide in spectrum range and long in service life. 本实用新型公开了一种宽光谱LED光源，包括壳体，壳体内设置电路板和LED灯板，LED灯板上设置多个LED灯珠，LED灯珠发出的光经菲涅尔透镜聚焦至光纤接口，菲涅尔透镜与光纤接口之间设有快门组件，快门组件、L
