Lens device with shading structure

A lens device with a shading structure, comprising:

• a control module, comprising a control circuit board and a photosensitive element installed at the control circuit board;
• a light emitting module, comprising a light source circuit board and a light emitting element installed at the light source circuit board, and the light source circuit board being electrically coupled to the control circuit board;
• a lens module, configured to be corresponsive to the photosensitive element and installed on a side of the control circuit board, and the lens module comprising a lens barrel and a plurality of lenses installed in the lens barrel;
• a focusing lens, installed at a front end of the lens modules;
• a reflector, installed between the lens module and the focusing lens, and capable of reflecting the light emitted by the light emitting element and passing the light out from the focusing lens;
• and
• a hood, coupled to the lens barrel, and having a shading section outwardly extending from a front edge of the lens barrel, for blocking and preventing the light reflected from the reflector from entering into the lens barrel directly.
