Claims40
A retaining bracket for a spotlight comprising:
- a rigid frame construction having a crossmember and bracket arms at end sections thereof including bracket bearings arranged for accommodating said spotlight;
- and
- said crossmember comprising a central supporting bearing for connecting the retaining bracket to a supporting apparatus,
- said crossmember and said bracket arms being connected via synchronously adjustable coupling elements to adjust the distance of the bracket bearings from one another in a self-centering fashion for accommodating spotlight housings of different sizes while keeping said supporting bearing automatically in the central position of said crossmember without displacement of the center of gravity with respect to said supporting bearing.
A retaining bracket for a spotlight with bracket bearings, which are arranged at the ends of the retaining bracket for accommodating a spotlight housing of the spotlight and comprising a central supporting bearing for connecting the retaining bracket to a supporting apparatus, wherein a distance of the bracket bearings from one another is adjustable in a self-centering fashion by a drive of an adapter drive and control module for accommodating spotlight housings of different sizes, wherein the adapter, drive and control module is connected to a focusing drive device for adjusting the light exit angle of the spotlight.
A retaining bracket for a spotlight with bracket bearings, which are arranged at the ends of the retaining bracket for accommodating a spotlight housing of the spotlight and comprising a central supporting bearing for connecting the retaining bracket to a supporting apparatus, wherein a distance of the bracket bearings from one another is adjustable in a self-centering fashion by a drive for accommodating spotlight housings of different sizes, wherein the bracket bearings are capable of being pivoted about a horizontal pivot axis for the purpose of setting an inclination of the spotlight, and wherein a maximum pivoting range of the spotlight is programmable and a program-controlled switch-off at limit is provided.
A retaining bracket for a spotlight with bracket bearings, which are arranged at the ends of the retaining bracket for accommodating a spotlight housing of the spotlight and comprising a central supporting bearing for connecting the retaining bracket to a supporting apparatus, wherein a distance of the bracket bearings from one another is adjustable in a self-centering fashion by a drive for accommodating spotlight housings of different sizes, wherein the bracket bearings are capable of being pivoted about a horizontal pivot axis for the purpose of setting an inclination of the spotlight, and wherein a pivoting speed of the spotlight is continuously regulable.
A retaining bracket for a spotlight comprising:
- a module for pivotably connecting to a support structure;
- a crossmember coupled to the module and comprising a center and having an adjustable length;
- a first bracket arm extending from the crossmember;
- a second bracket arm extending from the crossmember and being spaced apart from the first bracket arm;
- a first bracket bearing mounted to the first bracket arm for supporting the spotlight;
- and
- a second bracket bearing mounted to the second bracket arm for supporting the spotlight, wherein adjusting the length of the crossmember adjusts a spacing between the first and second bracket arms, wherein during adjustment said center is stationary.
A retaining bracket for a spotlight with bracket bearings, which are arranged at the ends of the retaining bracket for accommodating a spotlight housing of the spotlight and comprising a central supporting bearing for connecting the retaining bracket to a supporting apparatus, wherein a distance of the bracket bearings from one another is adjustable in self-centering fashion by a drive for accommodating spotlight housings of different sizes.
