Cutting is a physical action. Narrow cutting requires cutting objects with sharp implements. In math, there are extended "cutting lines", which can divide a plane into several parts.
The principle of moving head GOBO light is cutting of the beam with an electrical cutting function. The beam can be cut into arbitrary shapes as required by the scene and the shape of the spot. It is used compliment the needs of performers and the decoration of props. Currently the moving head profile are widely used as surface lighting. Excision of unnecessary miscellaneous light. For example, the light that shine only on the big screen, or shine only on the truss. It means that the area that shines should be lit to remove the area that is not bright. Make the stage cleaner and focus on the highlight.
In the moving head profile , a profile device has a revolving function. At present it is generally rotating at 90°, which can greatly improve the efficiency of cutting. Profile moving head lights need to have both, a zoom and a focus function to facilitate the change in facula and the size adjustment. This requires high uniformity. Profile moving head lights need to be equipped with CMY+CTO function to facilitate adjustment of color and color temperature.
Till recently, the high cost of moving head profile restricted their usage and as a result they were sparingly used that too for special occasions like TV program recording, drama etc.

The advantages of LED are long life, slow fading. The indication level can be customizable. Whereas, the advantage of the bulbs are that they have good color saturation and the range is far away. So in terms of cost, the LED with the same intensity / brightness is more expensive than the bulb.
The following are illustrations to substantiate the above:
