In one aspect, the present application is directed to a radiant energy emitting device. The radiant energy emitting device comprises (A) an outer housing including at least one aperture there through, the housing being operationally configured to (1) receive and contain radiant energy therein, and (2) emit radiant energy out through the aperture to a target surface; (B) an energy emission means; and (C) a sensor means disposed about the aperture of the housing, the sensor means being in communication with the energy emission means and operationally configured to detect the spatial relationship between the sensor means and the target surface, said spatial relationship determining activation of the energy emission means.
