Description

Technical Field

[0001] The invention relates to the field of lamps, and in particular to a stage lamp. Background Art

[0002] In order to realize the requirements of stage lights rotating in multiple directions and projecting light, multiple shaft structures are generally provided between the lamp head of the stage lamp and its supporting equipment. Usually, such stage lights are composed of a base, a support frame, and a lamp head. The shaft structure includes the shaft structure between the base and the support frame and the shaft structure between the support frame and the lamp head. In addition to being used to realize the rotation connection, the shaft structure also has the function of routing, thereby realizing the wire connection between the base, the support frame, and the lamp head. The various circuit boards, drive boards, light boards, etc. required in the stage lights are respectively arranged in the base, the support frame, and the lamp head. In order to realize the overall waterproofness of the stage lights, it is necessary to design waterproof structures for the three main components. The usual practice is to design waterproofness for the overall shell of the base, the support frame, and the lamp head to ensure that the circuit boards arranged inside are not exposed to rainwater, and then waterproofing is arranged at each shaft structure. This structure has certain requirements on the processing accuracy of the shell parts, and the larger the volume of the waterproof structure, the greater the probability of waterproof failure.

[0003] Since the lamp holder and the base usually have a relatively flat sealing contact surface, the waterproof structure design is relatively simple, while the support frame is usually U-shaped, composed of multiple pieces of sheet metal connected together, and the sealing parts are mostly arc-shaped, so the waterproof structure design is more difficult and it is easy to fail in waterproofing.
