<p>AbstractA reflective mask structure of projector lampThis invention relates to a reflective mask structure for projector lamp, which mainly comprises of an internally concave accommodate slot, in the mean time,at the front end of the accommodation slot, an opening is formed, and at least one luminescence device is installed in the accommodation slot; wherein, on the wall surface of accommodation slot, it is installed with a plurality of reflective bumped particulate; therefore, any optical ray projected onto reflective bumped particulate will generate reflection of different angle along the arc curved surfaceof reflective bumped particulate, meanwhile, back-and-forth and alternate reflection will be generated in accommodation slot so as to generate high density ray and to enhance the intensity and uniformity of the ray emitted by the luminescence device and to achieve the function of highly reflective efficiency illumination and remote illumination.Figure 1</p> |
