Color piece automatic switching device

Abstract

A color piece automatic switching device comprises a color piece clamp assembly and an automatic ejecting mechanism. The color piece clamp assembly comprises two or more color piece clamps. One side of each color piece clamp extends outwards and is provided with a connecting part. The connecting parts are connected with a rotating shaft. The automatic ejecting mechanism comprises two or more pulling rods, a push-pull limiting rod and a second reset spring used for resetting the displacement of the push-pull limiting rod. One end of each pulling rod is connected with the connecting part on the corresponding color piece clamp through a connecting rod. Each pulling rod is provided with a protrusion. The push-pull limiting rod comprises a connecting plate and a plurality of limiting plates arranged on one side of the connecting plate. A guide groove is formed between the adjacent limiting plates. The guide grooves are in one-to-one correspondence with the protrusions on the pulling rods. Each limiting plate extends to one side of the corresponding guide groove and is provided with a stop block. The side surface of each stop block is an oblique plane. Limiting grooves used for containing the protrusions are formed between the stop blocks and the connecting plate. According to the color piece automatic switching device, the multiple parallelly-arranged swing color piece clamps are switched through the automatic ejecting mechanism; the structure is simple; the size is small; and in addition, the purpose of quickly switching color pieces in a manual mode can be achieved.

Description

technical field [0001] The invention relates to the field of lamps, in particular to an automatic color chip switching device for changing the color of light emitted by a lamp. Background technique [0002] In the lighting lamps used for lighting, it is often necessary to adjust the color of the light to adjust the ambient atmosphere through the color or to produce a difference in the viewing angle of the human body. It can be used in entertainment, eye protection, medical treatment and other fields; such as stage lights (also known as moving head lights) , the variety of light color changes and the rapid switching of colors are particularly important to meet the needs of different stage scenes. [0003] The existing device for changing the light color is a color chip switching device, which includes an electric control box and manual control. The electronically controlled color chip switching device usually includes a disc and a drive motor that drives the disc to rotate. ...

AI Technical Summary

Problems solved by technology

The electronically controlled color chip switching device usually includes a disc and a drive motor that drives the disc to rotate. There are multiple color chips on the disc, and the purpose of switching color chips is achieved by rotating the disc. Although this kind of color chip switching method is more convenient , but during the rotation of the disk, multiple color chips will enter the light beam in turn, causing temporary color confusion in the process of switching color chips; in addition, if the number of color chips to be switched is large, a larger circle is required The color chip is installed with a disc, which makes the whole color chip switching device larger and the rotation switching time will be longer

Although the structure of the manual color chip switching device is relatively simple, it is necessary to remove the original color chip every time the color chip is replaced, and then move the color chip to be replaced into the light beam, which cannot achieve the purpose of quickly changing the color chip
