Atomizer, atomization module, optical path system and stage lamp thereof

Abstract

The present application relates to an atomizer, atomization module, light path system and stage lamp thereof, comprising a non-diffusion area allowing light to pass through and keep a certain direction of propagation and a diffusion area causing diffusion after light passing through, the non-diffusion area and diffusion area are internally and externally separated so that the diffusion area is located at the periphery of the non-diffusion area, wherein the diffusion area has a rough surface. Part of the light of the light source can still keep the original light path direction when passing through the non-diffusion area, reducing light diffusion, so that light energy can be more concentrated; while the other part of the light will produce chaotic light path when passing through the diffusion area, so that the light is dispersed, so that the light spot formed by the light source has high center illuminance and the edge of the light spot is more uniform and soft.

Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to an atomizer, atomizing module, optical path system and its stage light. Background Technology

[0002] In the field of optical lighting, achieving light homogenization through a combination of lens groups and atomizing sheets is a common technique. Traditional optical systems typically employ a cascaded structure of "lens + atomizing sheet," where the light emitted from the light source first undergoes optical path adjustment via a collimating lens or condenser lens, and then the atomizing sheet homogenizes the light spot. However, this existing technology has significant drawbacks, as shown in the attached figure. Figure 1 As shown: Central illuminance attenuation: In the process of achieving light spot uniformity, the atomizing plate inevitably causes multiple scattering of light. This scattering effect causes the energy distribution of the emitted light spot to tend to be uniform, which forces the high-energy central area (hot spot) originally formed by lens focusing to diffuse, resulting in a significant reduction in central illuminance (typical loss can reach 30%-50%).

[0003] Optical efficiency loss: To compensate for the decrease in central illuminance, existing solutions often require increasing the power of the light source, which not only increases system energy consumption but also leads to an increase in heat generation from the light source and shortens the lifespan of the device.

[0004] The trade-off between uniformity and brightness: Existing structures struggle to achieve uniform light spot while simultaneously meeting the brightness requirements of the central area. This deficiency is particularly pronounced in applications requiring high central illuminance, such as projection lighting and stage lighting.

[0005] There is an urgent need for a new type of optical structure that can significantly improve the illuminance in the central area while maintaining the uniformity of the light spot. Summary of the Invention

[0006] To solve one of the above-mentioned technical problems, this invention provides an atomizer, an atomizing module, an optical path system, and a stage light, which enables the light source to produce a light spot with high central illuminance and soft edge characteristics.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An atomizer includes a non-diffuse region that allows light to propagate in a specific direction after passing through it and a diffuse region that diffuses light after passing through it, wherein the non-diffuse region and the diffuse region are arranged inside and outside such that the diffuse region is located outside the non-diffuse region, and wherein the diffuse region has a rough surface.

[0008] Further defined, the non-diffuse region is a smooth surface located in the middle of the atomizer.

[0009] Further defined, the non-diffuse area is a light-transmitting hole located in the middle of the atomizer.

[0010] Further specified, the area of ​​the non-diffuse region must be larger than the area of ​​the diffuse region.

[0011] Further defined, the atomizer is a circular plate, the non-diffuse area is circular, and the diffuse area is annular, wherein the center of the atomizer, the center of the non-diffuse area, and the center of the diffuse area coincide.

[0012] An atomizing module includes the atomizer and a fixing plate for fixing the atomizer thereon. The fixing plate is connected to a motor drive mechanism, which drives the atomizer to move through the fixing plate so that the atomizer enters or exits the optical path.

[0013] An optical path system includes a light source, a first lens assembly, an atomizing module, and a second lens assembly arranged sequentially along the optical path.

[0014] Further defined, the atomizing module includes an atomizer having a non-diffuse region and a diffuse region, and the center of the light source, the main optical axis of the first lens assembly, the main optical axis of the second lens assembly, and the center of the non-diffuse region are on the same straight line.

[0015] A stage light, including the aforementioned optical path system.

[0016] By adopting the above technical solution, the present invention has at least the following beneficial effects: The atomizer has a non-diffuse region that allows light to propagate in a specific direction after passing through it, and a diffuse region that causes light to diffuse after passing through it. When some of the light from the light source passes through the non-diffuse region, it can still maintain the original light path direction, reducing light diffusion and making the light energy more concentrated; while when the other part of the light passes through the diffuse region, it will produce a chaotic light path, thus dispersing the light. In this way, the light spot formed by the light source has high central illuminance and more uniform and softer light spot edges. Attached Figure Description

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0020] As attached Figure 2 and attached Figure 3 As shown, an atomizer includes a non-diffuse region 11 that allows light to propagate in a specific direction after passing through it, and a diffuse region 12 that diffuses light after passing through it. The non-diffuse region 11 and the diffuse region 12 are positioned separately, with the diffuse region 12 located outside the non-diffuse region 11. The diffuse region 12 has a rough surface. A portion of the light from the light source 31 maintains its original light path direction when passing through the non-diffuse region 11, reducing light diffusion and concentrating the light energy. However, another portion of the light produces a chaotic light path when passing through the diffuse region 12, resulting in light dispersion (i.e., diffusion). Thus, the light spot formed by the light source 31 has high central illuminance and more uniform and softer edges. High central illuminance highlights details in the target area, suppresses background noise, and improves image clarity; while the soft light spot edges prevent glare or discomfort to the human eye caused by sudden changes in brightness, making it particularly suitable for long-term use. Simultaneously, it creates a natural transition of light and shadow, enhancing artistic expression.

[0021] One embodiment is shown in the appendix. Figure 2 As shown, the non-diffuse region 11 is a smooth surface located in the middle of the atomizer 1. The smooth surface can minimize the diffuse reflection or scattering of light, allowing more light to pass through in the expected direction. Of course, we also coat the smooth surface to improve the light transmittance and center illuminance.

[0022] Another embodiment, as shown in the appendix Figure 3 As shown, the non-diffuse area 11 is a light-transmitting hole opened in the middle of the atomizer 1. In this way, the light passing through the non-diffuse area 11 is not blocked or reflected, which can also improve the light transmittance and thus achieve the purpose of high center illuminance.

[0023] Specifically, the area of ​​the non-diffuse region 11 is larger than the area of ​​the diffuse region 12. The larger area of ​​the non-diffuse region 11 means that the area of ​​the diffuse region 12 that actually participates in atomization is relatively smaller, which can better ensure the intensity of the central illuminance.

[0024] Specifically, the atomizer 1 is a circular plate, with a non-diffuse region 11 that is circular and a diffuse region 12 that is annular. The center of the atomizer 1, the center of the non-diffuse region 11, and the center of the diffuse region 12 coincide. By designing the atomizer 1 as a circular plate and ensuring that the non-diffuse region 11 (the central circular area) and the diffuse region 12 (the outer annular area) are arranged concentrically, the atomizing medium can diffuse evenly outward from the annular diffuse region 12. This structure avoids the common problems of over-atomization in the central area or insufficient atomization at the edges in traditional atomizers 1, thus ensuring the uniformity and stability of the atomization coverage.

[0025] As attached Figure 4 As shown, this invention provides an atomizing module, including an atomizer 1 and a fixing plate 21 for fixing the atomizer 1 thereon. The fixing plate 21 is connected to a motor drive mechanism 22, which drives the atomizer 1 to move through the fixing plate 21, so that the atomizer 1 enters or exits the optical path. The motor drive mechanism 22 mainly includes components such as a motor, a transmission wheel, and a belt, thereby achieving automation of the atomizing module.

[0026] As attached Figure 5 As shown, this invention provides an optical path system including a light source 31, a first lens assembly 32, a fogging module, and a second lens assembly 33 arranged sequentially along the optical path. The fogging module includes a fogger 1 with a non-diffuse region 11 and a diffuse region 12. The center of the light source 31, the principal optical axis of the first lens assembly 32, the principal optical axis of the second lens assembly 33, and the center of the non-diffuse region 11 are on the same straight line. This design effectively reduces light loss; the coaxial design ensures that the light emitted from the light source 31 propagates along the lens optical axis, maximizing the light flux through the effective apertures of each lens assembly and the fogging module, avoiding edge occlusion or light energy waste caused by eccentricity, and improving imaging.

[0027] This invention also provides a stage light that utilizes the aforementioned optical path system, enabling the stage light to produce a light spot with high central illuminance and softer light spot edges, as shown in the attached figure. Figure 6 As shown.
