Abstract
Description
Technical Field
[0001] The embodiments of the utility model relate to the technical field of lighting fixtures, and in particular to a light-emitting lens module system, a lighting device and an auxiliary lighting fixture. Background Art
[0002] This section introduces the background technology that may be related to various aspects of the embodiments of the present utility model to the readers, and is believed to provide the readers with useful background information, thereby helping the readers to better understand various aspects of the embodiments of the present utility model. Therefore, it can be understood that the description in this section is used for the above purpose and does not constitute an admission of the prior art.
[0003] At present, drones are widely used in civil, commercial and military fields. In the civil field, more and more extreme sports enthusiasts use drones for filming. In the commercial field, in addition to carrying camera equipment to track and shoot various sports events, drones have also entered the agricultural field. In addition, with the development of science and technology, drones are more and more frequently involved in rescue at disaster sites. In order to provide rescuers with the latest information, drones are almost always equipped with camera equipment and lighting equipment. According to the rescue of trapped people at earthquakes, building collapses, and firefighting sites in recent years, it is not difficult to see that the efficiency and accuracy of search and rescue are the main reasons for whether trapped people can be successfully rescued. Drones are unmanned aircraft that have the advantages of being able to adapt to various harsh flight conditions and having a fast response speed, and are therefore used in search and rescue missions for various emergencies. The cameras carried by existing drones can only capture high-quality videos under good lighting conditions. However, at night or in dusty and sandy weather, traditional cameras cannot capture real-time images of disasters, which will have a great impact on the progress of disaster relief. The lighting lamps carried by existing drones are only suitable for close-range lighting, and it is difficult to penetrate thick clouds and fine sand layers. In addition, it is difficult for the lighting lamps to adjust the angle synchronously with the cameras, making it difficult for the cameras to capture high-quality images. Due to the problem of light, drones used in agriculture can usually only be used in clear weather. They cannot be used well on rainy days or when it is dark, which will affect work efficiency and be inconvenient to use. Utility Model Content

[0056] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0057] like Figures 1 to 3As shown, the embodiment of the utility model provides a light-emitting lens module system, which is configured to emit an illumination beam to a predetermined range, and includes: a light-emitting module 1, including: at least one light-emitting unit 11, configured to emit a light beam; and the lens assembly 2, including a plurality of collimating lenses 21, configured to collimate the light beam emitted by the light-emitting unit 11; it includes: a first lens 211, configured to collimate the light beam emitted by the light-emitting unit 11 for the first time; and a second lens 212, configured to collimate the light beam emitted through the first lens 211 for the second time; and a third lens 213, configured to collimate the light beam emitted through the second lens 212 for the third time; the light-emitting module 1, the first lens 211, the second lens 212 and the third lens 213 are arranged in sequence along the axial direction of the central axis of the lens assembly 2. The light-emitting lens module system provided by the embodiment of the utility model is described in detail below.
[0058] like Figure 1-Figure 3 As shown, in the embodiment of the utility model, the light-emitting unit 11 can be optionally an LED light-emitting diode, and the light-emitting angle of the LED light-emitting diode is 120 degrees. The LED light-emitting diode adopts 5050 package. The light-emitting unit 11 adds a gold wire for power supply, which increases the current load capacity of the light source, reduces the heat generation of the gold wire, and improves the electro-optical conversion rate of the LED light source, thereby increasing the luminous efficiency and service life of the light source. The LED light source removes the protective window, reduces the loss of light by the protective window, reduces the installation distance between the lens assembly 2 and the light source, and improves the coupling ability of the lens assembly 2 to the LED light source. The light-emitting module 1 also includes a light source fixing bracket, and a center hole is provided on the light source fixing bracket, and the LED light-emitting diode is arranged in the center hole. The center of the center hole is concentric with the center of the lens assembly 2. It effectively ensures that the optical center of the lens assembly 2 coincides with the light-emitting unit 11, greatly improving the imaging quality of the optical system. In the embodiment of the utility model, the light emitted by the light-emitting unit 11 passes through the first lens 211, the second lens 212 and the third lens 213 in sequence, compressing the 120-degree light diverged by the light-emitting module 1 to a final angle of about 10 degrees, which is a good optical condition for the front imaging lens.
[0059] like Figure 1-Figure 3As shown, in the embodiment of the utility model, in order to effectively ensure that the light emitted by the light emitting module 1 forms an effective optical condition after passing through the lens assembly 2, the first lens 211 is a lens with positive focal power, and at least one of the light incident surface and the light exit surface of the first lens 211 is an aspherical surface. The light incident surface of the first lens 211 abuts against the light emitting unit. The second lens 212 is a lens with positive focal power. The radius of curvature of the light incident surface of the first lens of the second lens 212 is smaller than the radius of curvature of the light exit surface. The third lens 213 is a lens with positive focal power. At least one of the light incident surface and the light exit surface of the third lens 213 is an aspherical surface. Of course, it can be understood that the first lens 211, the second lens 212 and the third lens 213 can also be single-curved lenses or hyperbolic lenses, and of course, single-curved lenses and hyperbolic lenses can be alternately mixed. As long as the focal lengths of the first lens 211, the second lens 212 and the third lens 213 meet the requirements of step-by-step collimation, the utility model can be implemented.
[0060] like Figure 2 and Figure 3 As shown, in the embodiment of the utility model, in order to effectively ensure the distance between the light emitting module 1, the first lens 211, the second lens 212 and the third lens 213 in the lens assembly 2, the coupling ability of the LED light source of the lens assembly 2 is improved. The light emitting lens module system also includes a lens barrel 4, in which a positioning groove 41 is arranged; the side surface of the first lens 211 cooperates with the side surface of the positioning groove 41, and the end surface of the first lens 211 abuts against the end surface of the positioning groove 41; the lens barrel 4 is also provided with a first limiting structure 401 that cooperates with the lens barrel 4; the first limiting structure 401 supports the distance between the first lens 211 and the second lens 212, so that the end surface of the second lens 212 facing the first lens 211 abuts against the light emitting surface of the first lens 211. The first limiting structure 401 cooperates with the lens barrel 4 to fix the first lens 201 and the second lens 202 in the lens barrel 4; the lens barrel 4 is also provided with a second limiting structure 402 that cooperates with the lens barrel 4; the second limiting structure 402 supports the distance between the second lens 212 and the third lens 213, and there is a gap 23 between the end surface of the third lens 213 facing the second lens 212 and the other end surface of the second lens 212, and the second lens 212 and the third lens 213 are fixed in the lens barrel 4 through the cooperation of the second limiting structure 402 and the lens barrel 4; it also includes a cover 43, which is arranged on the outside of the third lens 213; the cover 43 presses the third lens 213, so that the inner side of the third lens 214 abuts against the second limiting structure 402 and is fixed in the lens barrel 4.
[0061] like Figure 2 and Figure 3 As shown, in the embodiment of the utility model, due to the large scattering angle of the light emitted by the light emitting module 1, although part of the light has been collimated after passing through the first lens 211, there is still some light that is scattered and needs to be further collimated. In order to effectively allow all the light emitted after passing through the first lens 211 to enter the second lens 212, the radius of the second lens 212 is greater than the radius of the first lens 211. Although most of the light has been collimated after passing through the second lens 212, there is still some light that is scattered and needs to be collimated again. In order to effectively allow all the light emitted after passing through the second lens 212 to enter the third lens 213, the radius of the third lens 214 is greater than the radius of the second lens 212. After passing through the first lens 211, the second lens 212 and the third lens 213, all the light emitted will not be lost. All the light emitted by the light emitting module 1 will be emitted after passing through the lens assembly 2 without losing brightness. In order to effectively ensure that light is not reflected during the collimation process of the lens assembly 2, the vacuum-plated AR anti-reflection film on the first lens 211, the second lens 212 and the third lens 213 greatly reduces the loss of light. If the three lenses are not coated, the light energy will be lost by 24%.
[0062] To further demonstrate the advanced nature of the light-emitting lens module system provided by the utility model, the utility model embodiment also provides a lighting device, such as Fig.11 and Fig.12 , Fig.13 As shown, the lighting device includes: a lamp housing 5, a light-emitting lens module system 6 is arranged in the lamp housing 5, an outgoing collimating lens 51 is arranged on the lamp housing 5, and the outgoing collimating lens 51 is arranged on the light-emitting optical path of the light-emitting lens module system 6; the light-emitting lens module system 6 is the above-mentioned light-emitting lens module system. In the embodiment of the utility model, a sufficiently thick gap 50 is reserved between the light-emitting lens module system 6 and the outgoing collimating lens 51, and the size of the gap 50 determines the irradiation distance of the outgoing light. A large gap 50 can be used as a high beam lamp, and a small gap can be used as a low beam lamp. The outgoing collimating lens 51 adopts an aspherical lens, which reduces the use of spherical lenses and improves the imaging quality.
[0063] In order to further reflect the advancement of the lighting device provided by the utility model, the embodiment of the utility model also provides an auxiliary lighting fixture, such as Fig.11 and Fig.12 , Fig.13As shown, the auxiliary lighting fixture comprises: a bracket 7, a first lighting device 91 is connected to the bracket 7; the first lighting device 91 is connected to the bracket 7; the first lighting device 91 is the above-mentioned lighting device 91. The following is a detailed description of an auxiliary lighting fixture provided by an embodiment of the utility model.
[0064] In the embodiment of the utility model, the bracket 7 can be installed in different usage environments, such as stage lighting, drone lighting, etc.
[0065] In order to increase the application scope of the auxiliary lighting fixture, the auxiliary lighting fixture provided by the utility model embodiment also includes a second lighting device 92 and a third lighting device 93; the second lighting device 92 and the third lighting device 93 are arranged on both sides of the first lighting device 91. The output collimating lens 51 of the second lighting device 92 is arranged on the side of the lamp housing 5. In order to reduce the volume of the second lighting device 92 and the third lighting device 93 and change the light output direction, a reflective lens 90 is arranged on the light output path of the second lighting device 92; the output collimating lens 51 of the third lighting device 93 is arranged on the side of the lamp housing 5, and a reflective lens 90 is arranged on the light output path of the second lighting device 92. In this utility model embodiment, the first lighting device 91 can adopt a low beam design, and the second lighting device 92 and the third lighting device 93 adopt a high beam design, and the high beam and low beam designs are adopted to flexibly switch the lighting scheme.
[0066] like Figure 2 and Figure 3 As shown, in the embodiment of the utility model, in order to facilitate the adjustment of the irradiation position, the first illuminator 91 is connected to the bracket 7 through a movable connection mechanism 8; the second illuminator 92 and the third illuminator 93 are connected to the first illuminator 91 through a movable connection mechanism 8. The movable connection mechanism 8 can flexibly adjust the illumination angle. The first illuminator 91 can adjust the angle through the movable connection mechanism 8 to combine the second illuminator 92 and the third illuminator 93 into one to enhance the long-range illumination capability. The irradiation position of the first illuminator 91 can also be adjusted. Furthermore, the movable connection mechanism 8 is a universal joint.
[0067] In summary, the light-emitting lens module system, lighting device and auxiliary lighting fixture provided by the embodiments of the present invention form a Kohler lighting method through the light-emitting module, the first lens, the second lens and the third lens, and can provide a uniform and sufficiently bright lighting.
