     DETAILED DESCRIPTION OF THE INVENTION 
     The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims. 
     Referring to  FIGS. 2A and 2B , a reflecting structure of the invention includes a reflector A 01  having an inner surface which is a reflecting surface. The reflecting surface includes a plurality of strip reflecting surfaces  202   a ,  202   b ,  202   c  to  202   z  connected to each other to form a reflector having a J-shaped cross section which has a small curvature. Each of the strip reflecting surfaces has an inclined angle different from the inclined angles of other strip reflecting surfaces. The reflector A 01  has an outward reflecting region formed on an upper half portion of the reflector A 01  and including the strip reflecting surfaces from the strip reflecting surface  202   a  on a top of the reflector A 01  to the strip reflecting surface  202   m . The reflector A 01  further has an inward reflecting surface formed on a lower half portion of the reflector A 01  and including the strip reflecting surfaces from the strip reflecting surface  202   n  to the strip reflecting surface  202   z  on a bottom of the reflector A 01 . A light source  203  is disposed in a position near the strip reflecting surface  202   z  in the inward reflecting region. The distance between the strip reflecting surfaces to the center of the light source  203  gradually increases from the bottom to the top of the reflector A 01 . The dashed line  202   aa  representing the distance from the strip reflecting surface on the top of the reflector A 01  to the light source  203  is the longest, and the dashed lines  202   ga ,  202   ka  are shorter than the dashed line  202   aa . The dashed line  202   za  representing the distance from the strip reflecting surface on the bottom of the reflector A 01  to the light source  203  is the shortest. Therefore, the reflector A 01  formed by the strip reflecting surfaces has a spiral cross section. In this embodiment, the strip reflecting surfaces have an identical length, and the reflector is suitable for tubular light source, such as a fluorescent lamp or LED lamp. 
     Referring to  FIGS. 3A and 3B , the reflector A 01  of the invention reflects light to illuminate a banner. As shown in  FIG. 3A , the light source  203  is disposed in the inward reflecting region on the lower half portion of the reflector A 01 . The strip reflecting surface  202   z  determines the maximal projecting angle at which light is directly projected to a top of the banner  301 , and the strip reflecting surface  202   a  determines the minimal projecting angle at which the light is directly projected to a bottom of the banner  301 . The reflector A 01  limits a range of the light from the light source  203  to directly illuminate the banner. In addition to the light directly illuminate the banner, other light  304  from the light source  203  is reflected by the strip reflecting surfaces  202   a  to  202   m  in the outward reflecting region to reach a predetermined position on the banner. Referring to  FIG. 3B , some other light  306  is reflected by the strip reflecting surfaces  202   n  to  202   z  in the inward reflecting region to reach the outward reflecting region, and reflected by the strip reflecting surfaces in the outward reflecting surfaces again to reach the banner. As shown in  FIGS. 3A and 3B , all of light from the light source  203  reaches the banner  301  completely. Through adjusting reflection angle of each strip reflecting surface, illuminance of each projection region of the banner is regulated so as to obtain a uniform illuminance of the banner. 
     Referring to  FIGS. 4A and 4B , a reflecting structure of the invention suitable for ceiling lamps. A lamp C 01  has an anti-dust cover  401 . The anti-dust cover  401  includes a reflecting surface  402  disposed on an inner side of a top of the anti-dust cover  401  and at least two reflector A 01  disposed on an inner side of two lateral sides of the anti-dust cover  401 . The reflector A 01  has an inward reflecting region on a lower half portion and an outward reflecting region on an upper half portion. Light sources  403  and  404  are disposed in the inward reflecting region of the reflectors A 01 . The outward region includes a plurality of strip reflecting surfaces reflecting light  405  from the light sources  403  and  404 . The reflected light reaches the reflecting surface  402  and reflected by the reflecting surface  402  to illuminate a predetermined region below the lamp C 01 . Light from the light sources  403  and  404  emitting the inward reflecting region is reflected by the reflector A 01  twice to reach the predetermined region below the lamp C 01 . All light from the light sources  403  and  404  is reflected to reach the predetermined region below the lamp C 01 . 
       FIGS. 5A and 5B  depict the second the third embodiments of a reflecting structure of the invention. The reflector A 02  has a structure similar to the reflector A 01  of  FIG. 2 . However, the length of the strip reflecting surfaces gradually decreases from the upper half region to the lower half region. The strip reflecting regions  502  and  503  formed on two lateral side of the reflector A 02  are symmetrical so that each of the strip reflecting surfaces of the reflector A 02  is symmetrical with a central line  501  (a perpendicular line extending through a center point of the light source), and each strip reflecting surface is divided into two portions having the same length by the central line  501 . The reflector A 03  shown in  FIG. 5B  has a structure similar to the reflector A 01  shown in  FIG. 2 . However, the length of the strip reflecting surfaces gradually decreases from the upper half region to the lower half region. The strip reflecting regions  504  and  505  formed on two lateral side of the reflector A 02  are non-symmetrical so that each of the strip reflecting surfaces of the reflector A 02  is non-symmetrical with a central line  506  (a perpendicular line extending through a center point of the light source), and each strip reflecting surface is divided into two portions having a different length by the central line  506 . The reflectors A 02  and A 03  are suitable for light source of short tube type, such as high-density discharge lamp or single high-power light emitting diode for illuminating regions of different width. The reflector A 02  reflects light to illuminate a symmetrical region, whereas the reflector A 03  reflects light to illuminate a non-symmetrical region. 
       FIGS. 6A and 6B  depict the fourth embodiment of a reflecting structure of the invention. The reflecting structure includes a reflector A 04 . The reflecting surface includes a plurality of strip reflecting surfaces  602   a ,  602   b ,  602   c  to  602   z  connected to each other to form a reflector having a G-shaped cross section which has a small curvature. Each of the strip reflecting surfaces has an inclined angle different from the inclined angles of other strip reflecting surfaces. The reflector A 04  has an outward reflecting region formed on an upper half portion of the reflector A 04  and including the strip reflecting surfaces from the strip reflecting surface  602   a  on a top of the reflector A 04  to the strip reflecting surface  602   m . The reflector A 04  further has an inward reflecting surface formed on a lower half portion of the reflector A 04  and including the strip reflecting surfaces from the strip reflecting surface  602   n  to the strip reflecting surface  602   z  on a bottom of the reflector A 04 . A light source  601  is disposed in a position near the strip reflecting surface  602   z  in the inward reflecting region. The distance between the strip reflecting surfaces of the reflector A 04  to the center of the light source  601  gradually increases from the bottom to the top of the reflector A 04 . A line  608  through an edge of the light source to an edge of the bottom of the reflector A 04  extends to the strip reflecting surface  602   a  so that no light from a light source  601  reaches an illuminating region directly. In other words, all light from the light source  601  is reflected by the reflector A 04  to the illuminating region. Light  603  emitting to the outward reflecting region is reflected once to the illuminating region. Light  604  emitting to the inward reflecting region is reflected to the outward reflecting region and reflected by the outward reflecting region again to the illuminating region. Light  605  emitting to the inward reflecting surface is reflected to the outward reflecting region and further reflected by the outward reflecting region twice to the illuminating region. Light  606  emitting to the inward reflecting region is reflected by the inward reflecting region twice to the outward reflecting region and reflected by the outward reflecting region to the illuminating region. Light  607  emitting to a position near a bottom of the inward reflecting region is reflected by the inward reflecting region twice and further reflected by the outward reflecting region twice to the illuminating region. Thus, even the light source  601  is enclosed by the spiral reflector A 04 , light from the light source  601  is reflected by the reflector A 04  at most four times to reach the illuminating region. Light from a light source enclosed by a conventional C-shaped reflector or irregular shaped reflector is reflected dozens of times by the conventional C-shaped reflector or irregular shaped reflector to propagate out of the reflector and even most light cannot escape from the reflector, which reduces the illuminance of the illuminating region. 
       FIG. 7  depicts the fifth embodiment of a reflecting structure of the invention. The reflecting structure includes a reflector A 05 . The structure of the reflector A 05  is similar to the reflector A 01  of  FIG. 2 . The reflector A 05  includes a wide strip reflecting surface  702  having a width larger than other strip reflecting surfaces. A light source  701  including at least one LED is disposed on the wide strip reflecting surface  702 , and a plurality of fins are disposed on an outer surface of the reflector A 05  for heat dissipation.

The strip reflecting surface  801  is a second reflecting region which reflects light direct from a light source or light reflected by the outward reflecting region on the upper half portion of the reflector A 06  to an object. Referring to  FIG. 8B , a reflector A 07  includes at least two members joined to each other. Each of the described reflectors can be assembled by two members  802   a  and  802   b . Each of the members has a plurality of strip reflecting surfaces connected to each other.

The positioning structures  807  and  808  are joined together by a bolt  809  and a nut  810  or a spring which can be assembled or detached. 
     Referring to  FIGS. 9A and 9B , a lamp C 02  has a reflector A 07  further includes two lateral plates  901   a  and  901   b . Two light source sockets  902  and  903  are disposed on the lateral plates  901   a  and  901   b . At least one light source  904  is mounted to the light source sockets  902  and  903 .

     While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
