Abstract: A laryngoscope is provided and includes a handle, a blade assembly and a plurality of light emitting components. The blade assembly includes a supporting body and a sleeve body. The supporting body is pivotally connected to the handle. The sleeve body is sleeved outside the supporting body. The plurality of light emitting components are disposed on the supporting body and arranged in an arc shape on a first flat plane. Besides, at least one light divergence structure is optionally formed on the sleeve body for diverging light emitted from the plurality of light emitting components, and the supporting body optionally includes a supporting component and a heat dissipating component for conducting heat generated by the plurality of light emitting components to the supporting component. Therefore, the present invention can not only provide bright and wide illumination but also have anti-fogging function.
