     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0012]    The mobile illumination system for a golf course of the present invention comprises a lamp set  3  secured on a vehicle  4  by at least one supporting mechanism  31 .  
         [0013]    The vehicle  4  comprises wheels  41  for moving around and a steering wheel  42  to control direction of movement, and the power to drive the vehicle may be regular battery or solar power.  
         [0014]    The lamp set  3 , as shown in FIG. 2, comprises a plurality of spot lights  1  which are secured in the supporting mechanism  31  by a plurality of suspensions  32 , and a pair of small lamps  2  secured at the respective sides of the supporting mechanism  31  to light up the front of the vehicle  4  for driving purpose. The lamp set  3  uses an angle adjusting mechanism, such as a linking set or a gear set, to drive the spot lights  1  and to adjust the angle of the spot lights  1 . The lamp set  3  also can be driven directly by the angle adjusting mechanism to change the angle of the spot lights  1 .  
         [0015]    [0015]FIGS. 3 through 6 illustrates various embodiments of the angle adjusting mechanisms. As shown in FIG. 3, the lamp set  3  drives the spot lights  1  with a linking set. As shown in FIG. 4, the lamp set  3  drives the spot lights  3  with a gear set. As shown in FIG. 5, a linking rod directly drives the lamp set  3  to change the angle of the spot lights  1 . As shown in FIG. 6, a gear set directly drives the lamp set  3  to change the angel of the spot lights  1 .  
         [0016]    As shown in FIG. 3, a linking set is adapted to operate the spot lights  1 . The lamp set  3  comprises the supporting mechanism  31  with the suspensions  32  therein. Each of the spot lights  1  comprises a pair of lugs  11  protruding from the rear end with a shaft  12  connected to the suspension  32 , whereat the linking set comprises a linking rod  13 , a sliding block  14 , a threaded rod  15 , a motor  16  and a sleeve  17 . The bottom end of the spot light  1  is connected to one end of the linking rod  13  through a shaft  131 , while the other end of the linking rod  13  is pivoted to the sliding block  14  through another shaft  132 . The sliding block  14  is threaded to the threaded rod  15 , which then pivoted to the sleeve  17  driven by the motor  16 . Thus, by moving the sliding rod  14  along the threaded rod  15 , the spot light  1  is controlled to move forward or rearward and to adjust the angle of the spot lights  1 .  
         [0017]    [0017]FIG. 4 shows another embodiment of the angle adjusting mechanism, which uses a gear set to control the spot lights  1 , wherein the lamp set  3  comprises the supporting mechanism  31  with the suspensions  32  therein, each of the spot lights  1  has a pair of lugs  11  protruding from the rear end of the spot light  1  with a shaft  12  connected to the suspension  32 . The gear set comprises a motor  16  linking with a driving gear  161 , a first driven gear  19  and a second driven gear  18 , wherein the driving gear  161  meshes with the first driven gear  19 , which in turn meshes with the second gear  18 , which then fixed to the lugs  11 , so that the motor  16  drives the lugs  11  to control the angle of the spot lights  1 .  
         [0018]    Another embodiment, as shown in FIG. 5, uses a linking set to drive the lamp set  3 A directly and to change the angle of the spot lights  1 . The lamp set  3 A uses a shaft  311 A to secure itself to the supporting mechanism  31 A, and the bottom end of the lamp set  3 A protrudes a pair of lugs  33 A. The linking set includes a linking rod  13 , a sliding block  14 , a threaded rod  15 , a motor  16  and a sleeve  17 . The lugs  33 A of the lamp set  3 A are pivoted to one end of the linking rod  13  by a shaft  311 A, and the other end of the linking rod  13  is pivoted to the sliding block  14  by another shaft  132 , the sliding block  14  is threaded to the threaded rod  15 , which then pivoted to the sleeve  17  driven by the motor  16 . Thus, by moving the sliding rod  14  along the threaded rod  15 , the lamp set  33 A is controlled to move forward or rearward and to adjust the angle of the spot lights  1 .  
         [0019]    [0019]FIG. 6 shows a further embodiment of the angle adjusting mechanism that uses a gear set to control the lamp set  3 A directly. The lamp set  3 A is pivoted to the supporting mechanism  31 A through a shaft  311 A, and the bottom end of the lamp set  3 A protrudes a pair of lugs  33 A. The gear set includes a motor  16  which links with a driving gear  161 , a first driven gear  19  and a second driven gear  18  in sequence, the second driven gear  18  is fixed to the lugs  33 A. When the motor  16  is running, the lugs  11  are linked to move and further to adjust the angle of the spot lights  1 .
