Title: Reflecting structure of lamp

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a reflecting structure of a lamp, and more particularly to a reflecting structure suitable for vehicle head lights and street projecting lamps, capable of adjusting illuminating length and to reflect all light to a region to be illuminated. 
     2. Description of the Related Art 
       FIGS. 1A and 1B  depict a conventional vehicle head light and optical path thereof. A reflector  01  has an inner surface serving as a reflecting surface. The reflector  01  has a circular arc surface  006  and an inclined surface  007 . A light tube  002  is fitted to preset holes formed in the reflector  01 . A shielding sheet  003  is fixed to the circular arc surface  006  through a frame  013 . The shielding sheet  003  shields the light tube  002  to prevent light from the light tube  002  from dazzling a driver in a coming car, whereby high beam of the head light does not affect the driver in the coming car. 
     Referring to  FIG. 1A , when the light tube  002  illuminates, an emitting center  005  generates light beams of 360°. A part of the light beams  009  are shielded by the shielding sheet  003 . Some of these light beams are reflected to the reflector  01  and reflected by the reflector  01  to propagate out of the reflector  01 , and some of these light beams cannot leave the reflector  01 . Some light beams  010  are reflected by an arc-shaped reflecting surface on a top of the reflector and obstructed by the shielding sheet  003 . Therefore, the reflector with such a shielding sheet has a low illuminating efficiency. 
       FIG. 1B  depicts the optical path of the light from the light tube  002 . Light  011  propagates under a horizontal line, and light  012  propagates above the horizontal line. The light  012  may dazzle a driver in a coming car, which is the problem that even the shielding sheet  003  is used still cannot be solved. Therefore, such a conventional reflector reduce illuminating effect and cannot solve the dazzling problem. 
     Taiwan patent 1378871 “Headlamp Structure with Reflective Substrate”, discloses a headlamp structure having a reflective substrate. The headlamp structure includes a reflective substrate, a reflector and a lens. Light from a light source is reflected twice and refracted once to reach an illuminating region. To solve the dazzling problem, a hollow cylinder is disposed between the light source and a light reflecting region. The hollow cylinder however occupies a considerable space and reduces the illuminating efficiency.
