[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0030] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0031] New LED products are widely used. They can render different ambient colors through different colors of LED lights, and can produce good dyeing effects. They have been widely used in stage lighting, landscape lighting, commercial lighting and other fields. However, with the continuous changes in market demand and the continuous advancement of technology, traditional LED dyeing lights have been unable to meet users' needs for diversified and efficient lighting effects. Although the existing moving head dyeing lights on the market have broken through traditional technology to a certain extent, there are still some obvious problems. For example, the beam effect and dyeing effect of some moving head dyeing lights are relatively single, and complex and changeable stage effects cannot be achieved; at the same time, the visual effect of the light strip is insufficient, and the brightness of the light dyeing is not high enough, which is difficult to adapt to the needs of large-scale stages or high-brightness lighting.

[0032] In order to solve the above-mentioned technical problems, the present application provides an LED wash light optical system, which combines the LED beam wash optical system and the LED color effect system, which can not only achieve the beam effect and wash effect of conventional wash lights, but also increase the visual effect of the light strip and improve the brightness of the light wash; it can achieve rich and gorgeous stage effects such as color flowing effect, jump effect, and tailing effect.

[0033] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0034] See also Figure 1 In one embodiment of the present application, a LED dye light optical system is provided, the optical system comprising:

[0035] LED beam dyeing optical system 1, used to achieve beam effect and dyeing effect, including multiple single-group beam optical systems;

[0036] The single-group light beam optical system includes a first LED light source 11, a color mixer 12 and a condenser 13, see Figure 2 ;

[0037] LED color effect system 2, used to achieve the visual effect of the light strip and improve the coloring brightness to enhance the coloring effect; the LED color effect system 2 is distributed in a circular shape around the LED light beam coloring optical system 1;

[0038] The LED color effect system 2 includes a second LED light source 21 and an effect lens 22 .

[0039] The LED light beam dyeing optical system 1 and the LED color effect system 2 in the embodiment of the present application each have a separate control system.

[0040] Furthermore, the LED beam dyeing optical system 1 is used to achieve beam effects and dyeing effects, and can achieve a beam effect with a minimum angle of 3.5° and a dyeing effect with a maximum angle of 40°; specifically, the beam effect with a minimum angle of 3.5° means that the LED beam dyeing optical system 1 can produce a very focused beam of light, and its beam angle (i.e., the diffusion range of the beam) can be as small as 3.5°, producing a strong focusing effect. The dyeing effect with a maximum angle of 40° means that when the LED beam dyeing optical system 1 produces a dyeing effect, the diffusion range of the light can reach a maximum of 40°.

[0041] In the embodiment of the present application, multiple single-group beam optical systems are arranged in different shapes. Figure 3 Example 131 of an LED beam dyeing optical system in which a single group of beam optical systems are arranged in different shapes and Example 132 of an LED beam dyeing optical system in which a single group of beam optical systems are arranged in different shapes.

[0042] As one implementation mode, the first LED light source 11 can independently control the color and brightness output, and the user can finely adjust the color saturation and brightness of the light source according to specific needs to achieve the best visual effect.

[0043] As one implementation manner, the second LED light source 21 includes a plurality of single-group LED light sources arranged in a circular shape.

[0044] The single group of LED light sources includes LED light source color units 211 and LED light source white light units 212; the LED light source color units 211 and LED light source white light units 212 are alternately and evenly arranged, see Figure 4 .

[0045] Furthermore, the LED light source color unit 211 includes four LED light sources, namely, red R, green G, blue, and cold white CW. The LED light source white light unit 212 is a warm white light source. It can be seen that a single group of LED light sources has two white LEDs with different color temperatures, which has higher brightness, can achieve rich color mixing effects, can achieve different white light color temperature conversion effects, and can also improve the overall color shading brightness. Users can flexibly adjust the color temperature of the light source according to actual needs to achieve the best lighting effect.

[0046] In addition, the color and brightness output of each color in the LED light source color unit 211 can be controlled independently.

[0047] As one implementation, the effect lens 22 includes a plurality of effect lens units 221; the plurality of effect lens units 221 are arranged in a circular manner and combined into a whole, forming an effect lens 22 with a circular structure. Figure 5 The effect lens 22 of the present application is a circular effect lens 22 composed of four effect lens units 221, which is simple to process and has low cost.

[0048] As one implementation manner, the effect lens 22 is disposed above the second LED light source 21 .

[0049] Wherein, one side of the effect lens 22 is a plane, facing the second LED light source 21, and the other side is an irregular scattering particle surface 222, see Figure 6 .

[0050] Furthermore, the irregular scattering particle surface 222 in the effect lens 22 is used to scatter the light emitted by the second LED light source 21 .

[0051] Specifically, when the light emitted by the second LED light source 21 in the LED color effect system 2 passes through the irregular scattering particle surface 222 of the effect lens 22, the light is no longer limited to a single propagation path, but will be scattered to various angles around. The effect can be seen in the center of the stage or in the edge corners; this scattering effect not only makes the light softer and more uniform, but also greatly enhances the coverage of the light.

[0052] In summary, the present application provides an LED dyeing light optical system, including an LED beam dyeing optical system 1 and an LED color effect system 2. The LED beam dyeing optical system 1 includes multiple groups of beam optical systems, each group of beam optical systems includes a first LED light source 11, a color mixer 12 and a condenser 13; and the multiple groups of beam optical systems can be arranged in different shapes. The LED color effect system 2 includes a second LED light source 21 and an effect lens 22, and the LED color effect system 2 is distributed in a circular shape on the periphery of the LED beam dyeing optical system 1. This optical system can not only realize the beam effect and dyeing effect of conventional dyeing lamps, but also increase the visual effect of the light strip and improve the brightness of the light dyeing; the LED beam dyeing optical system 1 and the LED color effect system 2 have separate control systems respectively, and the combination of the two can realize rich and gorgeous stage effects such as color water effect, jump effect, and trailing effect.

[0053] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above embodiments are preferred implementation modes of the present application, but the implementation modes of the present application are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present application should be equivalent replacement methods and are included in the protection scope of the present application.
