Abstract

A moisture-proof spotlight includes a lamp housing, a support pivotally supporting the lamp housing from below and a lamp assembly pivotally installed inside the lamp housing, wherein the lamp housing contains therein a moisture-proof partition set provided for a vertical driving device and a horizontal driving device to affix thereto and also together installed inside the lamp housing for moisture-proof, thereby the defect of a conventional spotlight due to its horizontal driving device installed in the support tended to be affected by moisture is capably eliminated.

Claims

1. A moisture-proof spotlight comprising a lamp housing, a support pivotally supporting the lamp housing from below, and a lamp assembly pivotally installed inside the lamp housing, wherein the improvement comprises:

the lamp housing contains therein a moisture-proof partition set, a vertical driving device, a horizontal driving device and a stationary gear;

the moisture-proof partition set comprising a vertical partition and a horizontal partition, wherein the vertical partition divides an interior of the lamp housing into a lamp compartment for the lamp assembly pivotally installed therein and a driving-device compartment having a floor formed from the horizontal partition thereof;

the stationary gear being located below the horizontal partition of the moisture-proof partition set and combined with the support as an integrated structure by means of a fixing member;

the vertical driving device being fixed to the vertical partition of the moisture-proof partition set and used for driving the lamp assembly to tilt up and down in the lamp compartment of the lamp housing; and

the horizontal driving device being fixed to the horizontal partition of the moisture-proof partition set and used for driving the lamp housing and the lamp assembly to swivel right and left against the support.

2. The moisture-proof spotlight of claim 1, wherein the lamp housing is constructed from an upper half and a lower half.

3. The moisture-proof spotlight of claim 2, wherein the upper half has a first slot and the lower half has a second slot, and wherein the vertical partition of the moisture-proof partition set has laterals thereof inlaid to and retrained by the first slot and the second slot.
