A collapsible lighting fixture for photography and videography

Abstract

The invention relates to the technical field of lighting fixtures, and discloses a foldable photography and videography lighting fixture, which includes an adjustment box, the bottom of the adjustment box is fixedly installed with a first connecting shaft block, and the internal activities of the first connecting shaft block are respectively movable. A column and a support column are installed, and a movable ring is installed on the outside of the column. By rotating the third rotating shaft, the third rotating shaft can drive the first helical gear to rotate through the second helical gear when the third rotating shaft rotates. The gear is fixedly installed on the outside of the second rotating shaft, so that the first helical gear will drive the second rotating shaft to rotate, and the top of the second rotating shaft is fixedly equipped with a threaded block, and the threaded block is located inside the telescopic column. A threaded groove block matching the threaded block is provided inside, so that when the second rotating shaft rotates, the telescopic column can be driven up and down by the threaded block, thereby adjusting the height effect of the lamp.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a foldable photography and videography lighting fixture. Background technique [0002] Lamps are commonly used lighting tools in daily life, and in order to meet the different needs of users, the types of lamps can be varied, for example, there are foldable lamps and non-foldable lamps, and most lamps are generally relatively large and inconvenient to carry when going out. When foldable lamps are folded, it is easy to cause long-term bending or poor contact of the internal wires. In addition, when the lamps are installed, the lamps are generally fixed on the brackets. After installation, the lighting angle of the lamps is fixed and cannot be adjusted. If you want to change the angle, you can only disassemble it again, which increases the strength of the work [0003] After retrieval, Chinese Patent No. CN 105570845 B discloses a foldable lamp bracket and an LED lamp, i...

[0002] Lamps are commonly used lighting tools in daily life, and in order to meet the different needs of users, the types of lamps can be varied, for example, there are foldable lamps and non-foldable lamps, and most lamps are generally relatively large and inconvenient to carry when going out. When foldable lamps are folded, it is easy to cause long-term bending or poor contact of the internal wires. In addition, the lamps are generally installed on the bracket when the lamps are installed. After installation, the lighting angle of the lamps is fixed and cannot be adjusted. If you want to change the angle, you can only disassemble it again, which increases the strength of the work

[0003] After retrieval, Chinese Patent No. CN 105570845 B discloses a foldable lamp bracket and an LED lamp, including a base, a lamp holder and a limiting structure; When installing LED lamps, the limit structure is used to make the lamp frame and the base overlap or make the lamp frame and the base form an angle. According to the provided foldable lamp bracket, the lamp frame and the base can be folded together, which greatly reduces the size of the bracket and saves A lot of packaging and transportation costs reduce costs; the structure is simple, and there is no need to assemble the bracket parts into a bracket, which is convenient for users to use; but in actual use, the height of the lamp stand cannot be adjusted, and the distance between the lamp and the lamp stand The disassembly of the room is also relatively cumbersome, which is not conducive to the disassembly operation.
