The knob switch comprises a cover body, a twisting block, a circuit board and at least two electric connecting pieces, a containing groove is formed in the cover body, the circuit board and the twisting block are arranged at intervals, at least two conductive assemblies are arranged on the face, close to the twisting block, of the circuit board, and in one conductive assembly, the conductive assembly comprises a positive electrode bonding pad and a negative electrode bonding pad, each electric connecting piece is movably connected with one bonding pad in an abutting mode, and the electric connecting pieces are distributed in a radial mode around the central axis of the twisting block. The electric connecting pieces are arranged on the twisting block and are respectively used for being connected with the positive electrode bonding pad and the negative electrode bonding pad on the circuit board, and the positive electrode bonding pad and the negative electrode bonding pad of each conductive assembly are set to be different in power and different in output voltage, so that the electric connecting pieces are electrically connected with the positive electrode bonding pads and the negative electrode bonding pads which are different in power and different in output voltage; the knob switch is installed on a specific floodlight, the brightness is flexibly adjusted according to the brightness condition of a specific application environment, and the adjustability of the product is improved.
Description
technical field [0001] The invention relates to the technical field of lighting lamps, in particular to a floodlight and a knob switch thereof. Background technique [0002] The floodlight is a point light source that can illuminate evenly in all directions. The illumination range of the floodlight can be adjusted arbitrarily. The floodlight is the most widely used light source in the production of renderings. The standard floodlight can be used to illuminate. To brighten the entire scene, multiple floodlights can be used to illuminate at the same time, so that a brighter and more uniform light can be achieved. Floodlights are an indispensable light source for indoor or indoor lighting, and are widely used, such as, Can be used for indoor photography with good lighting. [0003] However, the power of the existing floodlights is usually fixed and does not have adjustable power, and the brightness cannot be flexibly adjusted according to the light and dark conditions of the s...
