     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIGS. 1 and 2 are the integral structure of the present invention, it is shown that the present invention is mainly comprised of a light emitted structure (A) and a shock proof structure (B). Said light emitted structure (A) is formed by a plurality of lampshades (2) the inner side of which is installed of a lamp (31), said lamp (31) is installed on a lamp base (3). After the lampshades have been assembled, then an upper cover (1) is attached to the top end of the lampshade (2), next bolts (4) is penetrated through the positioning bush (52) so to be fixedly lock on the buckling disk (5), another, the bolts (4) are regulated to the required length by the nut (52) on the bolts (4) so to form a complete light emitted structure (A). The number of the lamp on the light emitted structure is determined from the practical requirement (in this embodiment, for example, the number of lamp is three), and the light emitted structure thereof may be changed according to the user&#39;s requirement, ex. the lamp may be changed to LED (light emitted diode). Said buckling disk (5) has additionally two short bolts (51) for using to combine with a shock proof structure (B) which will be described in the following. 
     Now referring to FIG. 3, a shock proof structure (B) is installed below the light emitted structure (A), said light emitted structure is mainly comprised of an upper fixing disk (71), a fixing base (6), a plurality of spring (53), lower fixing disk (75) and bush (8). 
     Said upper fixing disk (71) has a circular shape, and a plurality of holes are located thereon, and the number of the holes are determined by the springs (will be described in the following), While a proper number of grooves are installed around the periphery thereof so to afterwards the structure may be easily installed into said bush (8). 
     A plurality of holes (61) are installed on the fixing base (6), the number of said holes (61) is the same as that of said spring as above the fixing disk (71) described hereinabove (in this embodiment, for easily describing, the number is three). A plurality of grooves are installed on the circumference of said fixing base. As said fixing disk (71), the number of the grooves is also matched with the structure of the nose portion (81) installed within said bush (8) so that it may be re-installed into said bush (8) and is buckled easily. 
     A plurality of springs (53) and (55)are installed on the upper and lower layers of said fixing base (6), and the springs on the upper and lower layers are aligned to each other, and further a bolt (54) is penetrated through said springs (53) and (55). 
     A lower fixing disk (75) is installed under the second spring (55), this lower fixing disk (75) has a shape the same as that of the upper fixing disk (71), a plurality of openings is installed, the number of which is also matched with said springs (53) and (55) (in the figure, three springs are shown). On the periphery of said opening is installed with a plurality of grooves which are matched with and having the same number as the grooves (63) of the upper fixing disk (71) and said fixing base (6). 
     As shown in FIG. 3, in assembling, said upper and lower springs (53) and (55) are aligned on the upper and lower ends of the fixing base (6), and after the upper fixing disk (71) and lower fixing disk (75) are aligned on the upper and lower sides of the spring (53), the bolt (54) is penetrated downwards through said fixing disk (71), spring (53), fixing base (6), spring (55) and lower fixing disk (75), and then it is locked on the thread hole (76) of the lower fixing disk (75), thus these components may be assembled together, the groove (63) of the fixing base (6) and the groove(74) of the lower fixing disk (75) are aligned to each other by the notches thereof, in order to be combined with the light emitted structure (A), thus the buckling disk (5) is fixed locked on the thread hole (72) of the upper fixing disk (71) by a bolt (51). 
     As said shock proof structure (B) is installed within said bush (8), the buckling disk (50) is positioning on the nose portion (81) as a pillar. Then the groove (74) of the upper fixing disk (71), the groove (63) of the fixing base (6) and the groove (77) of the lower fixing base (75) are slid inwards along the nose portion (81) of the bush (8). When the shock proof structure will be entered into said bush (8), since the buckling disk (5) has no groove, thus they are impossible to pass through the nose portion (81) for being buckling on the bush (8). After assembling, the fixing base (6) is properly rotated, it is designed that all the grooves will not aligned with said nose portion (81), thus they will not be dropped away. 
     Meanwhile, since the pillar is inserted into the opening of said fixing base (6), and is fixed by a bolt (62), thus the structure is as steady as possible so to attain the effect of combination, and then the pillar (9) is installed on the surface of a machine through a proper base. 
     As the finishing machine is used, the machine itself will produce dramatic vibrations, and further the alarm lamp will be resonant. Now, as shown in FIG. 6, if the vibrations occur, since the effect of said springs (53) and (55), the vibration will be absorbed, even the alarm lamp has some inclination, the vibration will also be absorbed by the springs. Therefore, the shock proof effect is attained. 
     Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
