Abstract
An optical scanning module includes a housing, a light source and a first heat-dissipating sheet. The light source is disposed inside the housing for emitting a source light to be projected onto the object. The light source includes an electrode wrapped by an electric-insulating and heat-conducting rubber. The first heat-dissipating sheet is arranged on a surface of the housing and in contact with the electric-insulating and heat-conducting rubber.
Claims4
An optical scanning module of an optical scanning apparatus for scanning an object, said optical scanning module comprising:
- a housing;
- a window arranged in a top surface of said housing;
