摘要： The invention provides a light spot adjustment mechanism, which includes at least one light cutter arranged between a light source and an illumination surface, which is adjustably arranged in the light emission direction of the light source and is suitable for changing the passing range of the light; and a driving mechanism configured for driving the movement of the light cutter. On the one hand, the light spot adjustment mechanism of the present invention can improve the accuracy of light spot adjustment and facilitate fine-tuning, so that the formed light spot has better adaptability to the illuminated object. On the other hand, it eliminates the tedious steps of manual operation and greatly improves the convenience of adjustment operations.

摘要： The present invention discloses a waterproof base convenient to maintain and a stage light fixture having the same. The waterproof base convenient to maintain includes a bottom frame which is integrally die-cast formed, and an upper cover with a pivoting hole covering the bottom frame. The upper cover includes a first cover body and a second cover body which are spliced to each other. The pivoting hole is formed by jointly splicing the first cover body and the second cover body, and an oil seal for sealing the outer side of a pivoting shaft penetrated the pivoting hole is disposed at the pivoting hole. The oil seal is mounted and fixed by a mounting plate. A first sealing strip seals the first cover body, the second cover body and the mounting plate with respect to each other, the first cover body and the second cover body abut against the bottom frame, and second sealing strips are disposed at abutting positions. According to the present invention, the upper cover is divided into the first cover body and the second cover body, and the pivoting hole is formed by jointly splicing the first cover body and the second cover body, so that it is possible to remove the upper cover from the bottom frame without disassembling other components to conduct convenient and quick maintenance on the interior of the waterproof base.
