Abstract: A light-beam generator and a projecting system having the light-beam generator are proposed in the present invention. The light-beam generator includes an optical element and a light-emitting diode, wherein the optical element further includes a non-spherical reflecting curved surface which at least has a focus. Also, the light-emitting diode is located at the focus of the optical element for emitting light to the reflecting curved surface to form a light beam which is guided in a specific direction. By such arrangement, an output efficiency of light beams can be improved and a heat dissipation requirement can be reduced. Additionally, the light-beam generator proposed in the present invention can be applied to a projecting system having illuminant with specific polarized directions, so as to eliminate various prior-art drawbacks.

Abstract: A motorcycle disc brake lock includes a lock body, a rotary base, a deadbolt, a locking card, a coil spring, a lock column and a twist spring. In using, a key is applied to turn around the rotary member of the lock column to actuate the rotary base rotate. The engage members of the locking card are guided and actuated to move up and get into the engage recesses of the rotary base by the sloped surfaces of the two prop projections in the chamber of the lock body. Thus, the deadbolt is moved upward, forming an unlocked condition. For locking, only insert the disc brake of a motorcycle into the deep opening of the lock body to slightly push up the deadbolt and force the locking card to move into the slide slots of the rotary base. Thus, the deadbolt is pushed down to have its bottom end inserted in a lock hole to lock the disc brake.
