DEFINITION
Classification: 362/19
(under the class definition) Subject matter comprising a light source which emits a ray of light having substantially equal components of wave energy in various directions transverse to the path of the ray and means to alter the light so that the ray has a greater wave energy component in one transverse direction than in another.
(1) Note. Where the illuminating devices includes only a reflector or other means which may incidentally polarize the light; the patent is not classified in this subclass. This subclass includes only illuminating devices where means are provided especially for the purpose of polarizing the light emitted by the light source. See the other appropriate subclasses for illuminating devices with reflectors, especially subclasses indented under subclass 296.
