WARNING LAMP ASSEMBLY

摘要

A warning lamp assembly includes a housing having an upper chamber and a bottom chamber; a driving unit; a gear mechanism including a rotary disk disposed within the upper chamber, and formed with an inwardly and radially extending retention flange, a bearing unit disposed on the retention flange so as to permit rotation of the disk relative to the upper chamber, a toothed wheel having outer peripheral teeth meshed with an axle of the driving unit and an inner periphery formed with downward projections slidably contacting the bearing unit and hence covering the same from above to prevent disengagement of the wheel from the rotary disk; a light source fixed within the upper chamber; and a parabolic reflector disposed on the wheel and covering the light source from above to reflect light rays emitted from the light source in a horizontal plane while simultaneously rotating together with the wheel.

1. A warning lamp assembly comprising:
a housing having an upper chamber and a bottom chamber below said upper chamber, a driving unit having an axle; a gear mechanism including a rotary disk disposed rotatably within said upper chamber, and formed with an inwardly and radially extending retention flange, a bearing unit disposed on said retention flange so as to permit smooth rotation of said rotary disk relative to said upper chamber, a toothed wheel disposed on said rotary disk having outer peripheral teeth meshed with said axle of said driving unit and an inner periphery formed with a plurality of downward projections extending into and slidably contacting said bearing unit and hence covering said bearing unit from above in such a manner to prevent disengagement of said toothed wheel from said rotary disk; a light source fixed within said upper chamber of said housing; and a parabolic reflector disposed on said toothed wheel and covering said light source from above to reflect light rays emitted from said light source in a horizontal plane while simultaneously rotating together with said toothed wheel; wherein, said bottom chamber of said housing is formed with mounting means for mounting the warning lamp assembly on a desired vehicle.
