Embodiment Construction
[0037] like Figure 1~4A waterproof stage lamp shown includes a lamp cap 1, a U-shaped frame 2 and a bottom box 3. The two sides of the lamp cap 1 are pivotally connected to the U-shaped frame 2, and the bottom of the U-shaped frame 2 is pivotally connected to the bottom box 3. The lamp cap 1 An opening 12 for heat dissipation is provided at the tail of the lamp cap 12. A supporting ring 121 protrudes from the periphery of the opening 12 along the central axis of the lamp cap 1. A first annular water retaining portion 122 protrudes from the outer edge of the supporting ring 121. The first The annular water retaining part 122 is perpendicular to the supporting ring 121; the waterproof stage light also includes a cover 9 matched and fixed with the opening 12, and an arc part 91 bent toward the opening 12 extends from the outer periphery of the cover 9, The arc portion 91 is separated from the tail of the lamp cap 1, and the inner surface of the cover 9 inside the arc portion 91 ...

The invention discloses a novel waterproof stage lamp which comprises a lamp holder, a U-shaped frame, a bottom box and a sealing cover. Two sides of the lamp holder are pivotally connected to the U-shaped frame, the bottom of the U-shaped frame is pivotally connected to the bottom box, a radiating opening is formed in the tail of the lamp holder, the periphery of the opening extends out along the central axis of the lamp holder to form a supporting ring, a first annular water retaining portion projects over the outer edge of the supporting ring and perpendicular to the supporting ring, the sealing cover is fixedly matched with the opening, the outer periphery of the sealing cover extends out to form an arc portion bent towards the opening, the arc portion is separated from the tail of the lamp holder, and a second annular water retaining portion projects over the inner side face of the sealing cover on the inner side of the arc portion along the central axis of the lamp holder, is positioned on the periphery of the first annular water retaining portion and is separated from the first annular water retaining portion to form a first radiating channel. A waterproof function can be effectively provided based on guarantee of radiating.
Description
technical field [0001] The invention relates to the field of stage lamps, in particular to a waterproof stage lamp. Background technique [0002] Stage lights generally include a U-shaped frame, a lamp head and a bottom box. The two sides of the lamp head are pivotally connected to the U-shaped frame through a rotating shaft. The U-shaped frame is provided with a horizontal rotational driving force. The bottom box is equipped with heating components such as a switching power supply, a driving mechanism, and a ballast, and the driving mechanism in the U-shaped frame and the driving mechanism in the bottom box are both heating components. In order to facilitate the installation of the shaft and facilitate heat dissipation, the shell of the lamp cap is often set as a split type, and the tail of the lamp cap is provided with a heat dissipation port for heat dissipation; The box is also set to be an open type with a heat dissipation port. Therefore, it is difficult to use stage...
