[0019] In order to make those skilled in the art 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.

[0020] 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.

[0021] See also Figure 1 and Figure 2 An embodiment of the present application provides a lamp 100 , which may be a photographic lamp, a stage lamp or other lamps 100 .

[0022] In some embodiments, the lamp 100 includes a light source module 10, a light processing module 20 and an imaging module 30. The light processing module 20 includes a lens unit 210 and an aperture 220. The lens unit 210 is located in the light output path of the light source module 10. The aperture 220 is located in the light output path of the lens unit 210. The lens unit 210 is configured to reduce the beam angle of the output light of the light source module 10 so that the output light passes through the aperture 220. The imaging module 30 is located in the light output path of the aperture 220.

[0023] Thus, the lens unit 210 of the light processing module 20 helps to reduce the incident angle of the light emitted from the light source module 10 before passing through the aperture 220, thereby helping to simplify the structure of the imaging module 30, reduce its complexity, and make the imaging module 30 lighter. In addition, the modular design of the lamp 100 helps to maintain the independence between the light source module 10, the light processing module 20 and the imaging module 30, making the installation, replacement or upgrade process of the module easier and faster, and helping to reduce maintenance costs.

[0024] As is known to all, the smaller the beam angle of the light beam entering the imaging module through the aperture, the lower the design requirements for the imaging module. At this time, the imaging module can be designed to be relatively light and easy to install. When the beam angle of the light beam entering the imaging module through the aperture is large, the design of the imaging module is very complicated. Multiple lenses need to be set inside the imaging module to reverse the offset problem caused by the beam angle, which makes the entire imaging module high in cost and weight, and is not conducive to the installation and adjustment of the imaging module. In addition, the large-angle light emitted by the light source module of the prior art, although the utilization rate of the light passing through the aperture is very high by setting the aperture at the focus of the light emitted by the light source module, increases the design cost of the imaging module, especially for some large aperture lighting systems. The existing design cannot reduce the cost of the imaging module while ensuring the light utilization rate.

[0025] The present application sets a light processing module 20 in front of the imaging module 30, and the lens unit 210 of the light processing module 20 can be adapted according to the size of the aperture 220 and the projection capability of the imaging module 30. For example, when the aperture 220 is large, the lens unit 210 can process the light emitted by the light source module 10 so that the angle of the light emitted by the lens unit 210 becomes smaller. According to the conservation of optical extension, the spot of the emitted light is larger at this time. Since it is a large aperture system, a light beam with a large spot and a small angle can also pass through the aperture 220, and the entire lamp 100 will also have a higher light utilization rate. Furthermore, the small angle light passing through the aperture 220 can also reduce the design complexity of the imaging module 30, improve the light utilization rate of the entire lamp 100 and reduce costs. The present application adds a lens unit 210 of the light processing module 20 to adapt the performance of the aperture 220 and the imaging module 30, improve the light utilization of the entire lamp 100 and reduce costs.

[0026] In some embodiments, the light source module 10 may emit monochromatic light or mixed light. For example, the light emitted by the light source module 10 may include white light, red light, green light, blue light, etc.

[0027] In some embodiments, the light source module 10 may include a light emitting unit 110 and at least one collecting lens 120, and the collecting lens 120 is used to receive and collimate the emitted light of the light emitting unit 110. In this way, the collecting lens 120 can collect and converge the emitted light of the light emitting unit 110, which helps to reduce the light scattering and loss of the light emitting unit 110, which helps to improve the utilization efficiency of the emitted light of the light emitting unit 110 and reduce light stray. In addition, the collimation effect of the collecting lens 120 on the emitted light of the light emitting unit 110 helps the light source module 10 form a more concentrated and directional light beam.

[0028] In some embodiments, the number of the collecting lenses 120 may be at least two, and the at least two collecting lenses 120 may be sequentially distributed along the light path of the light emitting unit 110. Figure 2 In the embodiment, the number of collecting lenses 120 is two.

[0029] In some embodiments, the light-emitting unit 110 may include a circuit board 111 and a plurality of LED light-emitting chips 112, and the plurality of LED light-emitting chips 112 may be arranged in an array on the circuit board 111. In this way, the light emitted by the light-emitting unit 110 is more uniform, and the array design is conducive to the heat dissipation of the LED light-emitting chips 112. For example, the heat generated by each LED light-emitting chip 112 can be directly conducted to the circuit board 111, and then dissipated through the heat dissipation system, which helps to maintain the LED light-emitting chips 112 within a suitable operating temperature range.

[0030] In addition, the LED light-emitting chip 112 is small in size and light in weight, so a more compact and lightweight product can be designed, which is easy to install in a small space. The LED light-emitting chip 112 starts quickly, does not need to be preheated, and has almost no flicker during operation, which is helpful for application scenarios that require frequent switching or have high requirements for light stability. The LED light-emitting chip 112 can convert electrical energy into light energy more efficiently, greatly reducing energy consumption, and the LED light-emitting chip 112 has good weather resistance, can work stably in a wide temperature range, is not affected by low or high temperatures, and is suitable for a variety of indoor and outdoor environments.

[0031] In some embodiments, the plurality of LED light emitting chips 112 may be arranged in an array to form a layout of multiple rows and columns.

[0032] In some embodiments, a plurality of LED light emitting chips 112 may be soldered to the circuit board 111 .

[0033] In some embodiments, the light source module 10 may further include a light homogenizing unit 130, which is located in the light path of the collecting lens 120 and is used to homogenize the light beam. In this way, the light homogenizing unit 130 helps to make the light distribution more uniform, helps to reduce the problem of local overbrightness or overdarkness of the light emitted by the light source module 10, makes the light softer and more comfortable, and helps to enhance the adaptability and adjustability of the lamp 100.

[0034] In some embodiments, the light homogenization unit 130 may include a compound eye lens or a diffuser. The compound eye lens can split and reintegrate the incident light beam through multiple tiny lens structures, and each microlens can independently regulate a small part of the light, thereby achieving fine homogenization of the light, making the emitted light more uniform, and helping to improve the imaging quality. The diffuser can scatter light through the microstructure inside the material, so that the light can be evenly dispersed in multiple directions after emission, which can effectively expand the coverage of the light and reduce the central hot spot. In this way, both the compound eye lens and the diffuser help to disperse and mix the emitted light of the collection lens 120, help reduce dark areas, and make the brightness distribution of the emitted light of the light source module 10 more uniform and consistent, which helps to improve the overall softness and comfort.

[0035] In some embodiments, when the light homogenizing unit 130 includes a fly-eye lens, the light homogenizing unit 130 may be a single fly-eye lens or a double fly-eye lens.

[0036] In some embodiments, the light source module 10 may further include a condenser lens 140, which is located in the light output path of the light homogenizing unit 130 and is used to guide the light to the lens unit 210. In this way, the condenser lens 140 can further concentrate and guide the light after the light homogenizing process, so that the light is more concentratedly directed to the lens unit 210, which helps to reduce the loss of light and ensure that more light is effectively used.

[0037] In some embodiments, the condenser lens 140 may be a plano-convex lens. For example, the light incident surface of the condenser lens 140 may be a convex surface, and the light emitting surface of the condenser lens 140 may be a plane.

[0038] In some embodiments, the lens unit 210 may include one or more lens elements sequentially located in the light output path of the light source module 10. In this way, one or more lens elements help the lens unit 210 to change the degree of divergence or convergence of light according to specific needs, thereby providing a more suitable light distribution for apertures 220 of different sizes and different imaging scenes. In addition, the configuration of multiple lens elements helps the lamp 100 to control light more finely, helps to improve the uniformity of imaging, and reduces unnecessary light loss. Moreover, by adopting a lens unit 210 composed of multiple lens elements, the design of a single complex lens can be replaced, which helps to simplify the overall structure of the lens unit 210, reduce the manufacturing difficulty and cost of the lens unit 210, and facilitate later maintenance and replacement.

[0039] In the present application, the term "plurality" means greater than or equal to two, for example, the number of lens elements may be two, three, four, five or other numbers.

[0040] In some embodiments, the lens unit 210 may include a negative lens 211 and a positive lens 212, and the negative lens 211 and the positive lens 212 are sequentially located in the light path of the light source module 10. In this way, the negative lens 211 and the positive lens 212 cooperate with each other to make more precise adjustments to the light emitted from the light source module 10. For example, the negative lens 211 can be used to diverge the light, and the positive lens 212 can be used to gather the light. The two work together to help achieve precise control of the propagation path and focal point of the light, and also help optimize the refraction and convergence process of the light, reduce the loss of light during the transmission process, and thus help improve the light utilization efficiency of the entire lamp 100.

[0041] In addition, the lens unit 210 can also change the beam angle and focusing degree of the light by adjusting the relative position or parameters of the negative lens 211 and the positive lens 212, so as to be applicable to imaging tasks of different distances and different areas, thereby helping to improve the versatility and flexibility of the lamp 100. Since the light is adjusted by directly utilizing the basic physical properties of the negative lens 211 and the positive lens 212, it can be more intuitive and easier to implement compared to a complex optical system design, thus helping to simplify the design process and reduce design costs.

[0042] In some embodiments, the negative lens 211 may be a convex lens, a concave lens or other types. For example, both the light incident surface and the light emitting surface of the negative lens 211 may be concave surfaces.

[0043] In some embodiments, the positive lens 212 may be a convex lens, a concave lens, or other types. For example, the light incident surface of the positive lens 212 may be a convex surface, and the light emitting surface of the positive lens 212 may be a flat surface.

[0044] In some embodiments, the imaging module 30 may include a first imaging lens 310 and a second imaging lens 320 , and the first imaging lens 310 and the second imaging lens 320 are movably distributed in sequence along the light-emitting optical axis of the aperture 220 .

[0045] In this way, the lamp 100 can adjust the beam angle and spot size of the light by adjusting the imaging module 30 according to actual needs. For example, by adjusting the positions of the first imaging lens 310 and the second imaging lens 320, the light can be effectively concentrated and light scattering can be reduced. This not only helps to enhance the controllability of the imaging direction of the lamp 100, but also helps to improve the accuracy of the imaging effect. The lamp 100 can flexibly adapt to different imaging needs and scene changes by adjusting the positions of the first imaging lens 310 and the second imaging lens 320 without the need for complex optical calculations or additional accessories, which also helps to enhance the versatility and adaptability of the lamp 100.

[0046] In some embodiments, the first imaging lens 310 and the second imaging lens 320 can move independently of each other. For example, the first imaging lens 310 can move toward or away from the second imaging lens 320 along the light-emitting optical axis of the aperture 220. For another example, the second imaging lens 320 can move toward or away from the first imaging lens 310 along the light-emitting optical axis of the aperture 220.

[0047] In some embodiments, the first imaging lens 310 may be a convex lens, a concave lens, a Fresnel lens, a spiral lens or other types. For example, both the light incident surface and the light exit surface of the first imaging lens 310 may be convex surfaces.

[0048] In some embodiments, the second imaging lens 320 may be a convex lens, a concave lens, a Fresnel lens, a spiral lens or other types. For example, both the light incident surface and the light emitting surface of the second imaging lens 320 may be convex surfaces.

[0049] In some embodiments, both the first imaging lens 310 and the second imaging lens 320 can be aspheric lenses. In this way, the first imaging lens 310 and the second imaging lens 320 can effectively correct the aberrations of light during propagation, such as spherical aberration and coma, so that the final image is clearer and has a higher contrast. In addition, the unique curved surface design of the aspheric lens helps the imaging lens to achieve precise focusing and control of light in a shorter optical path, which helps to reduce the volume and weight of the lamp 100, and also helps to reduce the demand for installation space, increase the flexibility of the design, and can more efficiently gather and guide light, reduce scattering and loss, thereby improving the energy efficiency of the entire lamp 100 and improving the brightness and imaging range of the lamp 100.
