Abstract

The invention discloses an LED (light emitting diode) light source device for visible near infrared light spectrum detection and application thereof. The LED light source device comprises a driving power supply, an LED luminous source, a sleeve, a support frame and a threaded ring, wherein the sleeve is arranged on the support frame; the LED luminous source is arranged in the left end of the sleeve; a light path assembly is arranged in the right end of the sleeve; internal screw threads are arranged at the inner wall of the right end; the LED luminous source is connected with the driving power supply; the light path assembly comprises a left flat convex lens, a diaphragm and a right flat convex lens which are sequentially arranged in the step hole end of the right end of the sleeve along the optical axis and are axially fixed through a threaded ring connected onto the internal screw threads of the right end of the sleeve. The emitted light rays directly illuminate a tested object; then, the projection spectrum is collected; the adaptation to different detection modes can be realized; the static transmission detection and the online dynamic detection are performed. The LED light source device has the advantages of energy saving and environment protection.

Description

technical field [0001] The invention relates to a light source device, in particular to an LED light source device for visible and near-infrared spectrum detection and its application, which can be used for transmission detection of different types of detection objects, and can be used for static detection or online detection.
