ABSTRACT:
The present invention is related to a shock endurable alarm lamp which is comprised of a light emitting structure and a shock proof structure. The light emitting structure is constructed from a plurality of lampshades and lamp base structures. A shock proof structure is installed on the bottom of the light emitting structure. The shock proof structure has two layers of spring structures installed on the upper and lower sides of a fixing base, and then a bolt is inserted downwards into the two layer structures for aligning the springs. Finally, a bushing covers the outside of the structure. Therefore, a shock proof structure is formed. Next, the whole structure is installed on a machine which needs an alarm lamp. The shock proof structure formed by the two sets of springs will cause oscillations induced from the machine to be absorbed, thereby sustaining the structure and stability of the alarm lamp.
