Dimming lamp

Abstract

The invention discloses a dimming lamp. The dimming lamp comprises a main lamp, multiple light distribution lamps, multiple adjusting devices and a controller. The multiple light distribution lamps are arranged on the periphery of the main lamp around the optical axis of the main lamp. The inner ends of the light distribution lamps are rotationally connected with the main lamp. The adjusting devices comprise multiple connection rods, movable pieces, screw rods and motors, wherein one end of each connection rod is hinged to the outer end of the corresponding light distribution lamp; the other end of each connection rod is hinged to the corresponding movable piece; the movable pieces are in threaded connection with the screw rods; the motors are in transmission connection with the screw rods to drive the screw rods to rotate in the axial direction of the screw rods. The controller controls the motors to drive the screw rods to rotate and the movable pieces can axially move along the screw rods, so that a pull rod drives the outer ends of the light distribution lamps to move, the light distribution lamps rotate relative to the main lamp, and the illumination range is changed. The multiple light distribution lamps are arranged around the optical axis of the main lamp and can rotate upwards or downwards at the same time, so that the condensation or light dispersion effect is converted. The dimming lamp is simple in structure and convenient to machine and produce.

Description

technical field [0001] The invention relates to a lighting device, in particular to a dimming lamp. Background technique [0002] In large public places, the lighting range required for different activities is different, and it needs to be adjusted according to the specific situation. In the existing technology, most of the lamps used in large public places do not have the adjustment function, and more lamps need to be installed, and different lamps are used according to the specific conditions to achieve different illumination ranges. However, this solution uses more lamps and the cost is high. And it takes up a lot of space. Therefore, there is a need for a lamp whose light can be adjusted, and different illumination ranges can be realized by using a dimming lamp. Contents of the invention [0003] The object of the present invention is to provide a dimming lamp whose illumination range can be adjusted, has a simple structure and is convenient for processing and produc...
