Description

Stage light with movable light source system

Technical field

The invention relates to a stage light with a movable light source system.

Background technique

In large-scale stage performances, evening parties, concerts, outdoor performances, etc., in order to create a stage effect that is ever-changing, colorful, or beautiful or cool, it is usually necessary to use multi-light stage lights and change the light source pattern to produce the above. stage effects.

In the prior art, LED stage lights are usually used, and the LED stage lights are generally fixed on the circuit board by a plurality of LED lamp beads (ie, multiple light sources), generally distributed in a circular or rectangular array; The LED lamp bead source is fixed. When you want to change the effect of the light source pattern (circular to rectangular, or rectangular to circular), you can only turn on or off the lamp bead at different positions. To achieve the change effect of the light source pattern.

This technique has the following disadvantages: First, for a stage lamp in which LED lamp beads are arranged in a rectangular array, since the lamp beads are fixed, when the rectangle is rounded by lighting or extinguishing the lamp bead at the corresponding position, It can only achieve a nearly circular shape, and can not form a complete circular shape with a smooth transition. The effect is not satisfactory. Secondly, the pattern generation process is static by the pattern of light beading and extinguishing, that is, changing from one pattern to another. The pattern has no visual dynamic effect; in addition, because the lamp bead is constantly lit and extinguished, it seriously affects the service life of the lamp bead (ie, the light source), while the part of the lamp is often used. The status of the lamp is very low. Similarly, for stage lights in which the LED bead is distributed in a circular array, shapes such as straight lines or triangles cannot be realized, and these shapes can be realized by stage lamps distributed in a rectangular array.
