Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a lamp, and more particularly to a multi-functional lamp capable of adjusting its illumination angle. 
         [0003]    2. Description of Prior Art 
         [0004]    Since people pay more and more attention to leisure activities, particularly to mild fitness exercises such as bicycle riding and jogging, as well as the concept of environmental protection arising from energy crisis and increasingly higher oil price, and bicycles consume no petroleum and cause no noise or pollution, therefore bicycles not just serve as a fitness equipment, but also provide a transportation means for commuters. In general, a bicycle usually comes with a passive reflective plate installed at the rear of the bicycle to reflect the light of a coming motor vehicle behind the bicycle, and the bicycle usually has no active illumination lamp, and thus it is relatively a high risk to ride the bicycle in a dark place. If a rider rides the bicycle on a rough road with obstacles and is not familiar with the road conditions, or even worse, there is a cliff in the front, it will be very dangerous and even fatal to ride the bike without having sufficient light and knowing the road conditions ahead. In the morning or at nighttime, it is also dangerous for joggers to jog or pedestrians to walk on a road since drivers cannot see the joggers or pedestrians easily in the dark, and thus the pedestrians or joggers usually wear a reflective ring to reflect the light from the motor vehicle to warn the drivers. However, the reflective plates or reflective rings are passive warning devices and cannot emit light, so that these devices can provide a low safety effect, and accidents may occur easily. 
       SUMMARY OF THE INVENTION 
       [0005]    Therefore, it is a primary objective of the present invention to provide a multi-functional lamp installed on a bicycle or worn by a user for supplying an illumination in a dark place, and an illumination angle of the lamp can be adjusted for illuminating a target area. 
         [0006]    To achieve the foregoing objective, the present invention provides a multi-functional lamp, comprising: 
         [0007]    a carrier module, including a base and a curved arm coupled to a side of the base, and the base having a shaft formed thereon, and the curved arm having a front through hole and a rear through hole formed thereon; 
         [0008]    a rotating element, having a cam shaft pivotally coupled to the shaft; 
         [0009]    a light emitting module, including a body coupled to the rotating element and a light emitting member installed at the body; and 
         [0010]    a compressing mechanism, including a rotating arm, a fastener module, a first pivot and a second pivot, wherein the first pivot is passed through the front through hole and coupled to the rotating arm, and the second pivot is passed through the rear through hole and coupled to the fastener module, and the fastener module is embedded and fixed into the rotating arm, and the rotating arm and the curved arm are enclosed to form a containing groove. 
         [0011]    The multi-functional lamp of the present invention can be installed onto a bicycle to achieve the effect of providing an active illumination at nighttime or in a dark place such as a tunnel or a forest trail, and the light emitting module illuminates the front to provide a clear driving direction to a bicycle rider, and the light emitting module can be rotated downward to illuminate the ground in order to avoid obstacles, pits or height difference of the road, and the multi-functional lamp can be worn onto a user&#39;s body or clamped onto a waist belt or a hat to provide illuminations for pedestrians, so as to prevent the pedestrians from tumbling or falling into a trap.
