DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1, an embodiment of the present application provides a lamp 100, and the lamp 100 is used to emit light to a light receiving surface to illuminate the light receiving surface. In this embodiment, the light receiving surface is a surface in the application environment of the lamp 100 for receiving light and displaying light effects, which can be a plane or a curved surface. The lamp 100 can form light spots, halos and other lighting effects on the light receiving surface to illuminate the application environment or create an atmosphere. In this embodiment, the lamp 100 can be a wall washer for forming light effects on the wall, and the wall is the light receiving surface. In this embodiment, the lamp 100 can be installed on the light receiving surface to increase the brightness of the light effect, and can also be set on other structures in the application environment, so that there is a large distance between the lamp 100 and the light receiving surface, so that the lamp 100 has a larger illumination range on the light receiving surface.

[0027] In the present embodiment, the lamp 100 includes a mounting member 10 and a plurality of light-emitting modules 20. The mounting member 10 is installed in the application environment. The mounting member 10 serves as the shell of the lamp 100 and constitutes the appearance structure of the lamp 100. In the present embodiment, the mounting member 10 has a housing space 11 and a light-emitting opening 12 connected to the housing space 11. The plurality of light-emitting modules 20 are arranged in the housing space 11 at intervals. The light emitted by the light-emitting modules 20 is transmitted to the outside of the housing space 11 and to the light receiving surface through the light-emitting opening 12. In the present embodiment, the light emitted by each light-emitting module 20 toward the light-emitting opening 12 forms a corresponding exit beam angle at the light-emitting opening 12. The light emitted by the light-emitting module 20 at least defines the exit beam angle with the structure of the mounting member 10. In the present embodiment, the exit beam angle of the light-emitting module 20 refers to the angle formed by the boundary of a certain range of light intensity in the light beam transmitted from the housing space 11 by the light-emitting module 20. In this embodiment, the optical axes of the plurality of light emitting modules 20 may be substantially parallel, so that the light from the plurality of light emitting modules 20 can substantially illuminate a designated area on the light receiving surface.

[0028] See also Figure 1 and Figure 2 In this embodiment, among the multiple outgoing beam angles corresponding to the multiple light-emitting modules 20, at least two outgoing beam angles are different, so that the lamp 100 has at least two outgoing beam angles. In this embodiment, the outgoing beam angle corresponding to each light-emitting module 20 is related to multiple factors, such as the divergence angle of the light-emitting module 20 itself, the distance between the light-emitting module 20 and the light-emitting opening 12, the position of the light-emitting module 20 in the accommodating space 11, etc.

[0029] In this embodiment, the lamp 100 includes a controller (not shown in the figure), which is disposed on the mounting member 10. The controller is disposed in the accommodation space 11 of the mounting member 10, and the controller is electrically connected to the plurality of light-emitting modules 20, respectively, and each light-emitting module 20 can be independently controlled by the controller. In an actual application scenario, the user can control one of the plurality of light-emitting modules 20 to emit light, and the output beam angle of the lamp 100 is the output beam angle of the light-emitting module 20.

[0030] As an example, the plurality of light-emitting modules 20 at least include a first light-emitting module 21, a second light-emitting module 22 and a third light-emitting module 23, and the three light-emitting modules 20 are arranged at intervals in the accommodating space 11. The three light-emitting modules 20 have different emission beam angles, and the emission beam angles of the light-emitting modules 20 range from 0° to the divergence angle of the light-emitting module 20 itself, such as 10°, 20°, 25°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, etc. For example, the emission beam angle of the first light-emitting module 21 is 25°, the emission beam angle of the second light-emitting module 22 is 50°, and the emission beam angle of the third light-emitting module 23 is 80°.

[0031] In actual application scenarios, the user can also control at least two of the multiple light-emitting modules 20 to emit light, and adjust the brightness ratio of the two light-emitting modules 20 to determine the output beam angle of the lamp 100, and the angle value of the output beam angle of the lamp 100 is between the angle values ​​of the output beam angles of the two light-emitting modules 20. For example, the first light-emitting module 21 and the second light-emitting module 22 emit light at the same time, and the output beam angle of the lamp 100 can be controlled within the range of [25°, 50°]. For example, the second light-emitting module 22 and the third light-emitting module 23 emit light at the same time, and the output beam angle of the lamp 100 can be controlled within the range of [50°, 80°]. For example, the first light-emitting module 21 and the third light-emitting module 23 emit light at the same time, and the output beam angle of the lamp 100 can be controlled within the range of [25°, 80°].

[0032] See also Figure 3In the present embodiment, the light emitting module 20 includes a light source 24, and the light source 24 may include a light bulb or an LED lamp bead. Taking the LED lamp bead as an example, the LED lamp bead may be a monochromatic lamp bead, such as white light, red light, green light, blue light, etc., the LED lamp bead may be a tricolor lamp bead, and the three colors of light may include red light, green light, and blue light, and the LED lamp bead may also be a five-color lamp bead, and the five colors of light may include red light, green light, blue light, warm white light, and cold white light. In the present embodiment, the light emitting module 20 also includes a light mixing cover 25, and the light mixing cover 25 irradiates the side of the light source 24 facing the light outlet opening 12. In the present embodiment, the light emitted by the light source 24 first transmits the light mixing cover 25 and then conducts out of the accommodating space 11. The light mixing cover 25 can improve the uniformity of the light of the light source 24, so that the light effect formed by the lamp 100 on the light receiving surface is uniform and soft.

[0033] In summary, the lamp 100 in this embodiment includes a plurality of light-emitting modules 20, and the light emitted by at least two light-emitting modules 20 forms different exit beam angles at the light exit opening 12. The controller can control any one or two or more light-emitting modules 20 to work, so that the lamp 100 has at least two exit beam angles. The lamp 100 can emit light at different exit beam angles to form different light effects, and the light effects may include the size of the light spot, the shape of the light spot, the brightness of the light spot, etc. In actual application scenarios, the lamp 100 can be applied to a variety of scenes, and each scene has different requirements for lighting effects. Users can use the lamp 100 in this embodiment to create different environmental atmospheres or achieve different degrees of lighting effects in the same environment, which greatly broadens the scope of use of the lamp 100, and there is no need to replace the lamp 100 to achieve different lighting effects, thereby reducing costs.

[0034] See also Figure 2 In the present application, the light emitting module 20 emits light in the accommodating space 11, and the light is transmitted to the outside of the accommodating space 11 through the light outlet opening 12. In the present embodiment, a light absorbing layer 13 is provided on the side of the mounting member 10 facing the accommodating space 11, and the side of the mounting member 10 facing the accommodating space 11 constitutes the inner wall of the accommodating space 11. The light absorbing layer 13 can absorb the light transmitted to the inner wall of the accommodating space 11, and prevent the light transmitted to the inner wall of the accommodating space 11 from being transmitted out of the accommodating space 11 after reflection, so that the light transmitted out of the accommodating space 11 is more uniform, and stray light is reduced, so that the light effect formed on the light receiving surface of the lamp 100 is more uniform, and the existence of a bright spot with a large brightness on the bright area on the light receiving surface is avoided, thereby improving the light effect of the lamp 100. In this embodiment, the light absorbing layer 13 can be a light absorbing film or a black coating, a black ink layer, etc. plated or attached on the inner wall of the accommodating space 11; it can also be the structure of the mounting member 10 itself. For example, if the mounting member 10 is a black plastic structure, the inner wall of the mounting space 111 is black and has the ability to absorb light to avoid light reflection.

[0035] In the present embodiment, the lamp 100 further includes a lens module 30, which is mounted on the mounting member 10 and approximately located at the light exit opening 12. In the present embodiment, the lens module 30 is disposed at the light exit opening 12, and the relationship between the lens module 30 and the light exit opening 12 can be various. As an example, if the size of the lens module 30 is larger than the size of the light exit opening 12, the lens module 30 is approximately in a state of covering the light exit opening 12. As another example, if the size of the lens module 30 is similar to the size of the light exit opening 12, the lens module 30 can be connected to the edge structure of the light exit opening 12 to be embedded in the light exit opening 12 and close the light exit opening 12. As another example, the lens module 30 is disposed in the accommodating space 11, and the lens module 30 is located between the light-emitting module 20 and the light exit opening 12. In this embodiment, the light emitted by each light-emitting module 20 passes through the lens module 30 and is transmitted out of the accommodating space 11. The order in which the light passes through the lens module 30 and the light output opening 12 is related to the positional relationship between the lens module 30 and the light output opening 12. For details, please refer to the three examples above.

[0036] In the present embodiment, the lens module 30 has a converging effect on the light, so that the light is more concentrated, which can improve the brightness of the lamp effect and improve the lighting efficiency. In the present embodiment, due to its light-converging characteristic, the lens module 30 has a certain influence on the outgoing beam angle of the light-emitting module 20, for example, it will reduce the outgoing beam angle. In the present embodiment, the lens module 30 includes a convex lens 31, and the convex lens 31 has a converging effect on the light. The curvature radius of the convex lens 31 ranges from [25mm, 50mm]. For example, the curvature radius of the convex lens 31 can be 25mm, 30mm, 35mm, 40mm, 45mm, 50mm. In the present embodiment, the curvature radius of the convex lens 31 is 30mm, and the curvature coefficient is -1. In other embodiments, the lens module 30 includes a concave lens 31 to have a diverging effect on the light.

[0037] In the present application, the structure of the mounting member 10 and the structure of the lens module 30 have multiple implementations, including at least three embodiments. In the three embodiments, the specifications (rated power, brightness, color, etc.) of the plurality of light-emitting modules 20 are the same.

[0038] See also Figure 2In the first embodiment, the accommodating space 11 is an integral space, and a plurality of light emitting modules 20 are arranged at intervals in the accommodating space 11, and the plurality of light emitting modules 20 share the same light exit opening 12 and the lens module 30. In the first embodiment, the lens module 30 is an integral lens 31 structure and is arranged at the light exit opening 12. In the first embodiment, the minimum distance between each light emitting module 20 and the light exit opening 12 is different, so that the exit beam angle of each light emitting module 20 is different. The smaller the minimum distance between the light emitting module 20 and the light exit opening 12, the larger the exit beam angle; the larger the minimum distance between the light emitting module 20 and the light exit opening 12, the smaller the exit beam angle. In this embodiment, the minimum distance between the first light-emitting module 21 and the light-emitting opening 12 is greater than the minimum distance between the second light-emitting module 22 and the light-emitting opening 12, and the minimum distance between the third light-emitting module 23 and the light-emitting opening 12. Therefore, the output beam angle of the first light-emitting module 21 is less than the output beam angle of the second light-emitting module 22, and the output beam angle of the third light-emitting module 23 is less than the output beam angle of the third light-emitting module 23.

[0039] In the first embodiment, a plurality of light-emitting modules 20 may be arranged linearly. Specifically, a plurality of light-emitting modules 20 are projected along the optical axis of the light-emitting module 20, and the plurality of light-emitting modules 20 are arranged along a designated straight line, and the designated straight line is approximately perpendicular to the light receiving surface. Under the setting of this embodiment, a plurality of light-emitting modules 20 are arranged in a direction gradually away from the light receiving surface, and the light effects formed by different light-emitting modules 20 on the light receiving surface have more overlapping parts. When two light-emitting modules 20 with different exit beam angles work at the same time, the overlapping parts of the light effects of the two light-emitting modules 20 are approximately located in the middle of the overall light effect, avoiding ghosting at the edge of the overall light effect, so that the light effect is uniform and symmetrical. In some other embodiments, a plurality of light-emitting modules 20 are distributed in an array, and a plurality of light-emitting modules 20 are projected along the optical axis of the light-emitting module 20, and a plurality of light-emitting modules 20 are arranged around a certain point. In such implementations, a plurality of light-emitting modules 20 are relatively dispersed, which can avoid that more structures of one light-emitting module 20 are located on the optical path of another light-emitting module 20, and can reduce stray light.

[0040] In other embodiments, the designated straight line is substantially parallel to the light receiving surface, or the relationship between the designated straight line and the light receiving surface is between parallel and perpendicular, that is, the angle between the designated light and the light receiving surface is between (0°, 90°), such as 30°, 45°, 60°, etc. In other embodiments, the light effects of the two light emitting modules 20 partially overlap and partially do not overlap, so that the entire light effect has at least two areas with different light and dark, so that the light effect has a stronger sense of hierarchy. For example, two or more light emitting modules 20 can be set to emit light at the same time, so that the lamp 100 forms a light effect with light and dark intervals, increasing the three-dimensional sense of the light effect.

[0041] See also Figure 1In the first embodiment, the accommodating space 11 is a cylindrical space, and the designated straight line intersects the axis of the accommodating space 11, so that the light effect formed by the lamp 100 is axially symmetrical, so that the light effect has a certain ornamental value. In some other embodiments, the accommodating space 11 is a space of other shapes, and the light effect of the lamp 100 is related to the shape of the accommodating space 11 and the shape of the light outlet opening 12, which will not be described in detail in this embodiment.

[0042] See also Figure 4 and Figure 5 In the second embodiment, the accommodating space 11 includes a plurality of installation spaces 111, and the light exit opening 12 is divided into a plurality of sub-openings 121, and the plurality of sub-openings 121 correspond to the plurality of installation spaces 111 one by one. In this embodiment, the mounting member 10 may include a plurality of shells connected in sequence, each shell having a hollow interior and defining an installation space 111, and the plurality of installation spaces 111 together constitute the accommodating space 11, and the sub-opening 121 is the opening of each shell. In some other embodiments, a plurality of plate wall-like partitions are provided in the accommodating space 11 to divide the accommodating space 11 into a plurality of areas (installation spaces 111), and to divide the light exit opening 12 into a plurality of sub-openings 121.

[0043] In this embodiment, a plurality of light-emitting modules 20 correspond to a plurality of installation spaces 111 one by one, and each light-emitting module 20 is installed in a corresponding installation space 111. The light emitted by each light-emitting module 20 is conducted out of the installation space 111 through a corresponding sub-opening 121, which can prevent one of the light-emitting modules 20 from being located in the light path of another light-emitting module 20, thereby preventing stray light. In a second embodiment, the plurality of sub-openings 121 have the same size, and at least two light-emitting modules 20 have different distances from the corresponding sub-openings 121, so that the two light-emitting modules 20 have different exiting beam angles. The smaller the minimum distance between the light-emitting module 20 and the corresponding sub-opening 121, the larger the exiting beam angle; the larger the minimum distance between the light-emitting module 20 and the corresponding sub-opening 121, the smaller the exiting beam angle. In the second embodiment, the minimum distance between the first light-emitting module 21 and the corresponding sub-opening 121 is greater than the minimum distance between the second light-emitting module 22 and the corresponding sub-opening 121, and the minimum distance between the third light-emitting module 23 and the corresponding sub-opening 121. Therefore, the output beam angle of the first light-emitting module 21 is less than the output beam angle of the second light-emitting module 22, and less than the output beam angle of the third light-emitting module 23.

[0044] In the second embodiment, the plurality of lens modules 30 include a plurality of lenses 31, the plurality of lenses 31 correspond to the plurality of sub-openings 121 one by one, each lens 31 is installed at a corresponding sub-opening 121, and each lens 31 covers a corresponding sub-opening 121. In this embodiment, the lens 31 includes a convex lens 31. In the second embodiment, the plurality of lenses 31 have the same curvature, and each lens 31 has the same degree of convergence effect on the corresponding light-emitting module 20, so that the exit beam angles of the plurality of light-emitting modules 20 can be adjusted by controlling the distance between the corresponding light-emitting module 20 and the sub-opening 121 so that the exit beam angles of the plurality of light-emitting modules 20 are different. In the second embodiment, each lens 31 has a light-incoming surface 311, and the light-incoming surface 311 faces a sub-opening 121 corresponding to the lens 31 to receive light from a corresponding light-emitting module 20. In the second embodiment, the light-incoming surfaces 311 of the plurality of lenses 31 are located in the same plane, so that the plurality of light spots formed by the plurality of light-emitting modules 20 are close to each other, so that the light effect of the lamp 100 has better integrity.

[0045] In the second embodiment, the outgoing beam angle of each light emitting module 20 is adjusted roughly by controlling variables, the variable is the minimum distance between the light emitting module 20 and the corresponding sub-opening 121, and the quantity includes the specifications of the light emitting module 20, the size of the sub-opening 121, the curvature of the lens 31, etc. Under the setting of the second embodiment, it is relatively simple to realize the operation of different outgoing beam angles of multiple light emitting modules 20, which is convenient for production and reduces design costs.

[0046] In the second embodiment, the geometric center of each sub-opening 121 is located on the optical axis of a corresponding light-emitting module 20 to avoid eccentric light effect. In this embodiment, the optical axis of the light-emitting module 20 refers to the center line of the light beam of the light-emitting module 20. Specifically, the outline of the installation space 111 in this embodiment is a right cylinder or a right prism, and the sub-opening 121 has approximately the same cross-section as the installation space 111. The axis of the installation space 111 coincides with the optical axis of a corresponding light-emitting module 20, and the geometric center of the sub-opening 121 is located on the optical axis of a corresponding light-emitting module 20. Under the setting of the second embodiment, the light derived from the sub-opening 121 is roughly a part of a right cone, and the light effect formed on the light receiving surface is roughly symmetrical. In some other embodiments, the shapes of the installation space 111 and the sub-opening 121 can have different settings, which will not be repeated here.

[0047] In the second embodiment, a plurality of light-emitting modules 20 may be arranged linearly. Specifically, a plurality of light-emitting modules 20 are projected along the optical axis of the light-emitting module 20, and the plurality of light-emitting modules 20 are arranged along a designated straight line, and the designated straight line is perpendicular to the light receiving surface. Under the setting of this embodiment, a plurality of light-emitting modules 20 are arranged in a direction gradually away from the light receiving surface, and the light effects formed on the light receiving surface by different light-emitting modules 20 have a large number of overlapping parts. When two light-emitting modules 20 with different emission beam angles work at the same time, the overlapping part of the light effects of the two light-emitting modules 20 is roughly located in the middle of the overall light effect, avoiding ghosting at the edge of the overall light effect, making the light effect uniform and symmetrical.

[0048] See also Figure 6 and Figure 7 In the third embodiment, the accommodating space 11 includes a plurality of installation spaces 111, and the light outlet opening 12 is divided into a plurality of sub-openings 121, and the plurality of sub-openings 121 correspond one-to-one to the plurality of installation spaces 111. A plurality of light-emitting modules 20 correspond one-to-one to the plurality of installation spaces 111, and each light-emitting module 20 is installed in a corresponding installation space 111. The light emitted by each light-emitting module 20 is conducted out of the installation space 111 through a corresponding sub-opening 121, which can prevent one of the light-emitting modules 20 from being located in the light path of another light-emitting module 20, and avoid the occurrence of stray light. In the third embodiment, the sizes of the plurality of sub-openings 121 are different. The distances between the plurality of light-emitting modules 20 and the corresponding sub-openings 121 may be the same, or the distances between at least two light-emitting modules 20 and the corresponding sub-openings 121 may be different, so that the exit beam angles of the plurality of light-emitting modules 20 are different. When the distances between the plurality of light-emitting modules 20 and the corresponding sub-openings 121 are the same, the larger the size of the sub-opening 121, the larger the angle of the outgoing beam; the smaller the size of the sub-opening 121, the smaller the angle of the outgoing beam. The smaller the minimum distance between the light-emitting module 20 and the corresponding sub-opening 121, the larger the angle of the outgoing beam; the larger the minimum distance between the light-emitting module 20 and the corresponding sub-opening 121, the smaller the angle of the outgoing beam.

[0049] In the third embodiment, the plurality of lens modules 30 include a plurality of lenses 31, the plurality of lenses 31 correspond to the plurality of sub-openings 121 one by one, each lens 31 is installed in a corresponding sub-opening 121, and each lens 31 covers a corresponding sub-opening 121. In this embodiment, the lens 31 includes a convex lens 31. In the third embodiment, the size of the plurality of lenses 31 is adapted to the setting of the corresponding sub-opening 121, the radius of the plurality of lenses 31 is different, and the curvature of the plurality of lenses 31 is the same, so that each lens 31 has the same degree of convergence effect on the corresponding light-emitting module 20, reducing the factors affecting the outgoing beam angle of the light-emitting module 20 and reducing the difficulty of adjusting the outgoing beam angle. In the second embodiment, each lens 31 has a light-incoming surface 311, and the light-incoming surface 311 faces a sub-opening 121 corresponding to the lens 31 to receive light from a corresponding light-emitting module 20. In the second embodiment, the light-incoming surfaces 311 of the plurality of lenses 31 are located in the same plane, so that the plurality of light spots formed by the plurality of light-emitting modules 20 are close to each other, so that the light effect of the lamp 100 has better integrity.

[0050] In the third embodiment, the geometric center of each sub-opening 121 is located on the optical axis of a corresponding light-emitting module 20 to avoid eccentric light effects. Specifically, the profile of the installation space 111 in this embodiment is a right cylinder or a right prism, and the sub-opening 121 has approximately the same cross-section as the installation space 111. The axis of the installation space 111 coincides with the optical axis of a corresponding light-emitting module 20, and the geometric center of the sub-opening 121 is located on the optical axis of a corresponding light-emitting module 20. Under the setting of the third embodiment, the light derived from the sub-opening 121 is roughly a portion of a right circular cone, and the light effect formed on the light receiving surface is roughly symmetrical. In some other embodiments, the shapes of the installation space 111 and the sub-opening 121 may have different settings, which will not be elaborated here.

[0051] In the third embodiment, a plurality of light-emitting modules 20 may be arranged linearly. Specifically, a plurality of light-emitting modules 20 are projected along the optical axis of the light-emitting module 20, and the plurality of light-emitting modules 20 are arranged along a designated straight line, and the designated straight line is perpendicular to the light receiving surface. Under the setting of this embodiment, a plurality of light-emitting modules 20 are arranged in a direction gradually away from the light receiving surface, and the light effects formed on the light receiving surface by different light-emitting modules 20 have a large number of overlapping parts. When two light-emitting modules 20 with different emission beam angles work at the same time, the overlapping part of the light effects of the two light-emitting modules 20 is roughly located in the middle of the overall light effect, avoiding ghosting at the edge of the overall light effect, making the light effect uniform and symmetrical.

[0052] The present embodiment provides a lamp 100, which includes a mounting member 10 and a plurality of light-emitting modules 20. The mounting member 10 has a housing space 11 and a light-emitting opening 12 connected to the housing space 11. The plurality of light-emitting modules 20 are arranged in the housing space 11 at intervals. The light emitted by the light-emitting modules 20 is transmitted to the outside of the housing space 11 and to the light receiving surface through the light-emitting opening 12. In the present embodiment, the light emitted by each light-emitting module 20 toward the light-emitting opening 12 forms a corresponding exit beam angle at the light-emitting opening 12, and there are at least two different exit beam angles. The controller can control any one or two or more light-emitting modules 20 to work, so that the lamp 100 has at least two exit beam angles.

[0053] In the setting of this embodiment, the lamp 100 has at least two exit beam angles. The lamp 100 can emit light at different exit beam angles to form different light effects, and the light effects may include the size of the light spot, the shape of the light spot, the brightness of the light spot, etc. In actual application scenarios, the lamp 100 can be applied to a variety of scenes, each of which has different requirements for lighting effects. Users can use the lamp 100 in this embodiment to create different ambient atmospheres or achieve different degrees of lighting effects in the same environment, which greatly broadens the scope of use of the lamp 100, and there is no need to replace the lamp 100 to achieve different lighting effects, thereby reducing costs.
