Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to an electric control method for light output angle, an optical structure and a lighting device. Background Art

[0002] There are two common ways to focus lamps:

[0003] First, the light output angle can be adjusted by manually adjusting the optical components or light source components to control the relative position of the optical components and the light source. However, the adjustment accuracy of the mechanical structure is poor and manual adjustment is required, which is inconvenient and time-consuming.

[0004] Second, by intelligently adjusting the optical components or light source components, the relative position between the optical components and the light source components is adjusted to achieve the adjustment of the light output angle, or the optical components are configured to correspond to different light output angles, such as the invention patent application with application number CN202411850932.5. It drives the optical components to be combined with lenses with different light output angles to achieve the adjustment of the light output angle. This requires the addition of an electric motor and a transmission structure, resulting in a complicated structure, an increased overall volume, and increased manufacturing costs.

[0005] Therefore, in order to avoid a significant increase in the cost of lamps and a complication of their structure, such as the invention patent application with application number CN202411098349.3, two groups of corresponding light sources and optical components are assembled, and different light sources are switched on and off to achieve adjustment of the light output angle. Although its structure is relatively simple, it utilizes the opening and closing of two groups of light sources to achieve switching of three light output angles. If it is necessary to increase the switching of different light output angles, it is necessary to increase the number of light sources and the corresponding number of lenses with different light output angles. The adjustment range of the light output angle is relatively limited to the support of the number of light sources and the number of different lenses. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an electric control method, optical structure and lighting equipment that is easy to adjust and can be performed with a lamp of simple structure, thereby reducing the preparation cost of the lamp, and can achieve the adjustment of the light output angle without being limited by the number of light sources and the number of different lenses.

[0061] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0063] The present application provides a method for electrically controlling a light output angle. The method comprises the following steps: obtaining a light output angle adjustment parameter of a lamp; performing angle adjustment difference processing on the light output angle adjustment parameter and a preset light output angle parameter to obtain a light output angle difference; detecting whether the light output angle difference is less than or equal to the preset angle difference; and, when the light output angle difference is less than or equal to the preset angle difference, sending a lens brightness signal to a lighting control unit to adjust the light source output brightness percentage of the corresponding lens in the lamp.

[0064] In order to better understand the electronic control method of the light output angle of the present application, the electronic control method of the light output angle of the present application is further explained below:

[0065] The electronic control method of the light output angle in one embodiment includes some or all of the following steps:

[0066] S100: Obtaining a light output angle adjustment parameter of a lamp. It is understood that the light output angle adjustment parameter is the light output angle that the lamp needs to adjust. By collecting the light output angle, it is convenient to determine the light output angle adjustment target of the lamp.

[0067] S200, perform angle adjustment difference processing on the light-emitting angle adjustment parameter and the preset light-emitting angle parameter to obtain the light-emitting angle difference. It can be understood that the light-emitting angle adjustment parameter is the light-emitting angle required to be adjusted by the lamp. By collecting the light-emitting angle, it is convenient to determine the light-emitting angle adjustment target of the lamp. The preset light-emitting angle parameter is the light-emitting angle of the light formed by the standard lens in the optical structure when the corresponding light source is fully lit, that is, the light-emitting angle of the light emitted by the standard lens corresponding to the brightness percentage of the light source is 1, and the number of groups of standard lenses and corresponding light sources is at least two, that is, the preset light-emitting angle parameter is the light-emitting angle of the light independently emitted by the standard lens corresponding to the brightness percentage of at least two light sources is 1, that is, the preset light-emitting angle parameters are at least two. By performing angle adjustment difference processing on the light-emitting angle adjustment parameter and the preset light-emitting angle parameter, it is convenient to determine the difference between the light-emitting angle adjustment parameter and the light-emitting angle of the standard lens.

[0068] S300, detect whether the light output angle difference is less than or equal to the preset angle difference. It can be understood that the light output angle adjustment parameter is the light output angle that the lamp needs to adjust. By collecting the light output angle, it is convenient to determine the light output angle adjustment target of the lamp. The preset light output angle parameter is the light output angle of the light formed by the standard lens in the optical structure when the corresponding light source is fully lit, that is, the light output angle of the light emitted by the standard lens corresponding to the brightness percentage of the light source is 1, and the number of groups of standard lenses and corresponding light sources is at least two, that is, the preset light output angle parameter is the light output angle of the light independently emitted by the standard lens corresponding to at least two light sources when the brightness percentage is 1, that is, the preset light output angle parameter is at least two. By processing the angle adjustment difference between the light output angle adjustment parameter and the preset light output angle parameter, it is convenient to determine the difference between the light output angle adjustment parameter and the light output angle of the compared standard lens. The preset angle difference specifies a range of light-emitting angles, that is, the difference in light-emitting angles between standard lenses with numerically adjacent light-emitting angles. By forming a relationship between the light-emitting angle difference and the preset angle difference, it is convenient to select at least two lenses whose light-emitting angles of the standard lenses are close to the light-emitting angle adjustment parameters.

[0069] S400: When the light-emitting angle difference is less than or equal to the preset angle difference, a lens-selected illumination brightness signal is sent to the lighting controller to adjust the percentage of the light source output brightness of the corresponding lens in the lamp. It can be understood that the preset angle difference is a specified light-emitting angle range, that is, the difference in light-emitting angles between standard lenses with adjacent light-emitting angles. The light-emitting angle difference is less than or equal to the preset angle difference, indicating that the light-emitting angle adjustment parameter falls within the specified light-emitting angle range, facilitating the selection of at least two lenses whose light-emitting angles of the standard lenses are close to the light-emitting angle adjustment parameter, thereby facilitating the adjustment of the light source output brightness of each corresponding lens on the lamp, so that the lamp outputs a light-emitting angle different from or the same as that of the standard lens based on the light source of the existing lens, thereby achieving convenient adjustment of the light-emitting angle. The structure only requires at least two lenses and at least two light sources in a one-to-one correspondence, which is simple in structure and low in manufacturing cost. The light-emitting angle adjustment range is achieved beyond the limitations of the number of light sources and the number of different lenses, which is conducive to achieving convenient adjustment of multiple light-emitting angles while reducing costs.

[0070] The above-mentioned electric control method of the light output angle determines the target light output angle of the lamp after obtaining the light output angle adjustment parameter, and processes the angle adjustment difference between the light output angle adjustment parameter and the preset light output angle parameter to determine the degree of deviation between the target light output angle of the lamp and the light output angle of the standard lens. Finally, according to the above-mentioned light output angle deviation, it is determined whether it falls within the specified light output angle range, so as to facilitate the adjustment of the light source output brightness of the selected standard lens on the lamp, so that the lamp can output the light output angle different from or the same as the standard lens according to the light source of the existing lens, thereby realizing convenient adjustment of the light output angle. Structurally, it only requires at least two lenses and at least two one-to-one corresponding light sources, so it is simple in structure and has low preparation cost. It also realizes that the adjustment range of the light output angle breaks through the limitations of the number of light sources and the number of different lenses, which is conducive to realizing convenient adjustment of multiple light output angles while reducing costs.

[0071] In one embodiment, through multiple groups of light sources and corresponding lenses in the optical structure, different lenses and corresponding light sources have different preset light output angles when the brightness percentage is 1, as follows:

[0072]

[0073] The light sources and corresponding lenses on the optical structure are at least two groups of lenses a-f1, and the lenses a-f1 on the optical structure and the corresponding light sources have different preset light output angles when the brightness percentage is 1.

[0074] Furthermore, through multiple groups of light sources and corresponding lenses in the optical structure, different lenses and corresponding light sources have different preset light output angles when the brightness percentage is 1, as follows:

[0075]

[0076] The light sources and corresponding lenses on the optical structure are at least two groups of lenses a1 - f1 . The lenses a1 - f1 on the optical structure and the corresponding light sources have different preset light output angles when the brightness percentage is 1.

[0077] In one embodiment, the light sources in the optical structure have the same light emission direction, and the light incident surfaces of the standard lenses face the same direction, and the light exit surfaces of the standard lenses also face the same direction. This allows the brightness of the light sources corresponding to at least two selected standard lenses to be adjusted to effectively output a light emission angle that is different from or the same as that of the standard lenses. In other words, the light beam outputted by the at least two standard lenses has a light emission angle that is different from or the same as that of the standard lenses.

[0078] In one embodiment, when the light-emitting angle difference is greater than the preset angle difference match, the light-emitting angle adjustment parameter is compared with the light-emitting angle of the next standard lens, that is, the angle adjustment difference processing of the light-emitting angle adjustment parameter and the next preset light-emitting angle parameter is performed until at least two standard lenses are selected, and the light source output brightness of the selected standard lens on the lamp is adjusted so that the light-emitting angle of the lamp according to the light source output of the existing lens is different from or the same as the light-emitting angle of the standard lens.

[0079] In one embodiment, performing angle adjustment difference processing on the light output angle adjustment parameter and the preset light output angle parameter to obtain the light output angle difference specifically includes:

[0080] The difference between the light-emitting angle adjustment parameter and the first preset light-emitting angle is calculated to obtain a first light-emitting angle difference.

[0081] It can be understood that the light output angle adjustment parameter is the light output angle that the lamp needs to adjust. By collecting the light output angle, it is convenient to determine the light output angle adjustment target of the lamp. The first preset light output angle is one of the light output angles of each standard lens. That is, the first preset light output angle is the light output angle of the light formed by the standard lens when the corresponding light source brightness percentage is 1. The difference between the light output angle adjustment parameter and the first preset light output angle is conveniently determined.

[0082] Furthermore, a difference between the light-emitting angle adjustment parameter and the second preset light-emitting angle is calculated to obtain a second light-emitting angle difference.

[0083] It can be understood that the light output angle adjustment parameter is the light output angle that the lamp needs to adjust. By collecting the light output angle, it is convenient to determine the light output angle adjustment target of the lamp. The second preset light output angle is the other light output angle of each standard lens. That is, the second preset light output angle is the light output angle of the light formed by the other standard lens when the corresponding light source brightness percentage is 1. The difference between the light output angle adjustment parameter and the second preset light output angle is conveniently determined.

[0084] In one embodiment, detecting whether the light angle difference is less than or equal to a preset angle difference specifically includes:

[0085] Detect whether the first light output angle difference is less than or equal to the preset angle difference.

[0086] It can be understood that the first light-emitting angle difference is obtained based on the light-emitting angle adjustment parameter and the first preset light-emitting angle. The light-emitting angle adjustment parameter is the light-emitting angle required to be adjusted by the lamp. By collecting the light-emitting angle, it is convenient to determine the light-emitting angle adjustment target of the lamp. The first preset light-emitting angle is one of the light-emitting angles of each standard lens, that is, the first preset light-emitting angle is the light-emitting angle of the light formed by one of the standard lenses when the corresponding light source brightness percentage is 1. By the difference between the light-emitting angle adjustment parameter and the first preset light-emitting angle, it is convenient to determine the difference between the light-emitting angle adjustment parameter and the light-emitting angle of one of the standard lenses. The preset angle difference specifies the light-emitting angle range, that is, the difference in light-emitting angles between two standard lenses with adjacent light-emitting angle values, that is, the difference between the light-emitting angles of the light formed by two standard lenses with adjacent light-emitting angle values when the corresponding light source brightness percentage is 1, that is, each of the two compared standard lenses corresponds to a preset angle difference. By forming a relationship between the first light-emitting angle difference and the preset angle difference, it is convenient to select one of the standard lenses with a light-emitting angle close to the light-emitting angle adjustment parameter.

[0087] Furthermore, when the first light output angle difference is less than or equal to the preset angle difference, a third brightness signal is sent to the lighting central controller to adjust the light source output brightness percentage of the lens corresponding to the third preset light output angle.

[0088] It can be understood that the preset angle difference is a specified light-emitting angle range, that is, the difference in light-emitting angle between standard lenses with numerically adjacent light-emitting angles. The first light-emitting angle difference is less than or equal to the preset angle difference, indicating that the light-emitting angle adjustment parameter falls within the specified light-emitting angle range, which facilitates the selection of a standard lens whose light-emitting angle is close to one of the lenses with the light-emitting angle adjustment parameter, thereby facilitating the adjustment of the light source output brightness of the selected standard lens, so that the lamp outputs a light-emitting angle different from or the same as that of the standard lens according to the light source output of the existing lens.

[0089] Furthermore, it is detected whether the second light output angle difference is less than or equal to the preset angle difference.

[0090] It can be understood that the second light-emitting angle difference is obtained based on the light-emitting angle adjustment parameter and the second preset light-emitting angle. The light-emitting angle adjustment parameter is the light-emitting angle required to be adjusted by the lamp. By collecting the light-emitting angle, it is convenient to determine the light-emitting angle adjustment target of the lamp. The second preset light-emitting angle is another of the light-emitting angles of each standard lens, that is, the second preset light-emitting angle is the light-emitting angle of the light formed by another standard lens when the corresponding light source brightness percentage is 1. By using the difference between the light-emitting angle adjustment parameter and the second preset light-emitting angle, it is convenient to determine the difference between the light-emitting angle adjustment parameter and the light-emitting angle of another standard lens. The preset angle difference specifies the light-emitting angle range, that is, the difference in light-emitting angles between two standard lenses with adjacent light-emitting angle values, that is, the difference between the light-emitting angles of the light formed by two standard lenses with adjacent light-emitting angle values when the corresponding light source brightness percentage is 1, that is, each of the two compared standard lenses corresponds to a preset angle difference. By forming a relationship between the first light-emitting angle difference and the preset angle difference, it is convenient to select another standard lens with a light-emitting angle close to the light-emitting angle adjustment parameter.

[0091] Furthermore, when the second light-emitting angle difference is less than or equal to the preset angle difference, a second brightness signal is sent to the lighting central controller to adjust the light source output brightness percentage of the lens corresponding to the second preset light-emitting angle.

[0092] It can be understood that the preset angle difference is a specified light-emitting angle range, that is, the difference in light-emitting angles between standard lenses with adjacent light-emitting angles. The second light-emitting angle difference is less than or equal to the preset angle difference, indicating that the light-emitting angle adjustment parameter is within the specified light-emitting angle range, which facilitates the selection of another lens whose light-emitting angle of the standard lens is close to the light-emitting angle adjustment parameter, thereby facilitating the adjustment of the light source output brightness of the two selected standard lenses, so that the lamp outputs a light-emitting angle that is different from or the same as that of the standard lens according to the light source output of the existing lens. In this way, convenient adjustment of the light-emitting angle is achieved through electrical control. The structure only requires at least two lenses and at least two light sources corresponding to each other. The structure is simple and the preparation cost is low. The adjustment range of the light-emitting angle breaks through the limitations of the number of light sources and the number of different lenses, which is conducive to convenient adjustment of multiple light-emitting angles while reducing costs.

[0093] In one embodiment, detecting whether the light angle difference is less than or equal to a preset angle difference specifically includes:

[0094] Detecting whether the first light output angle difference is equal to the preset angle difference;

[0095] When the first light output angle difference is equal to the preset angle difference, a first-level brightness signal is sent to the lighting central controller to adjust the light source output brightness percentage of the lens corresponding to the first preset light output angle to 0, and adjust the light source output brightness percentage of the lens corresponding to the second preset light output angle to 1.

[0096] It can be understood that the light output angle adjustment parameter is equal to the light output angle of one standard lens, and then the standard lens is selected and sent to the lighting controller, and the percentage of the light source brightness corresponding to the selected standard lens is output as 1, and the percentage of the light source brightness corresponding to the other standard lens is 0, that is, the light output of the lamp according to the existing lens is the same as the light output angle of the standard lens.

[0097] In one embodiment, after the light output angle adjustment parameter is determined, the relationship between the light source brightness percentage corresponding to the selected standard lens, the first preset light output angle, and the second preset light output angle is as follows:

[0098] Divide the first preset light output angle (X) to the second preset light output angle (Y) into 11 equal parts, and fill in the angle columns in the table below in sequence. Then, each of the 11 equally divided angles corresponds to a specific brightness percentage, where the values of brightness percentages a and b are the same for any first preset light output angle and second preset light output angle, where a is the light source output brightness percentage corresponding to the standard lens selected by the first light output angle difference; b is the light source output brightness percentage corresponding to the standard lens selected by the second preset light output angle, as shown in Table 1 below.

[0099] Table 1

[0100]

[0101] When the light output angle adjustment parameter (d) is the same as the value in the angle column in Table 1, that is, when d=c, the corresponding output brightness percentage a of the light source corresponding to the standard lens selected by the first light output angle difference and the corresponding brightness percentage b of the light source corresponding to the standard lens selected by the second light output angle difference are directly output;

[0102] When the light output angle adjustment parameter (d) is different from the value in the angle column in Table 1, the light source output brightness percentage a corresponding to the standard lens selected by the first light output angle difference and the light source output brightness percentage b corresponding to the standard lens selected by the second light output angle difference satisfy the following relationship:

[0103] 1)a=a1+(a2-a1)*[(d-c1) / (c2-c1)]

[0104] Wherein, c1 and c2 are the values of two adjacent groups in the angle column, c2>c1, and c2>d>c1, a1 is the a value corresponding to c1, and a2 is the a value corresponding to c2;

[0105] 2)b=b1+(b2-b1)*[(d-c1) / (c2-c1)]

[0106] Wherein, c1 and c2 are the values of two adjacent groups in the angle column, c2>c1, and c2>d>c1, b1 is the b value corresponding to c1, and b2 is the b value corresponding to c2;

[0107] In particular, when the first preset light output angle is 6° and the second preset light output angle is 10°, the data in Table 2 is obtained by substituting Table 1 into Table 1, as shown in Table 2:

By collecting the light output angle, it is convenient to determine the light output angle adjustment target of the lamp. The third preset light output angle is one of the light output angles of each standard lens. That is, the third preset light output angle is the light output angle of the light formed by one of the standard lenses when the corresponding light source brightness percentage is 1. The difference between the light output angle adjustment parameter and the third preset light output angle is conveniently determined.

[0115] Furthermore, a difference between the light-emitting angle adjustment parameter and a fourth preset light-emitting angle is calculated to obtain a fourth light-emitting angle difference.

[0120] Detect whether the third light-emitting angle difference is less than or equal to the first preset angle difference.

[0121] It can be understood that the third light-emitting angle difference is obtained based on the light-emitting angle adjustment parameter and the third preset light-emitting angle. The light-emitting angle adjustment parameter is the light-emitting angle that the lamp needs to adjust. By collecting the light-emitting angle, it is convenient to determine the light-emitting angle adjustment target of the lamp. The third preset light-emitting angle is one of the light-emitting angles of each standard lens, that is, the third preset light-emitting angle is the light-emitting angle of the light formed by one of its standard lenses when the corresponding light source brightness percentage is 1. By using the difference between the light-emitting angle adjustment parameter and the third preset light-emitting angle, it is convenient to determine the difference between the light-emitting angle adjustment parameter and the light-emitting angle of one of its standard lenses. The first preset angle difference specifies the light-emitting angle range, that is, the maximum difference in the light-emitting angles between the standard lenses with three adjacent light-emitting angles, that is, the maximum difference between the light-emitting angles of the three lenses with adjacent light-emitting angle adjustment parameters and the corresponding light source brightness percentage is 1, that is, each of the three compared standard lenses corresponds to a first preset angle difference. Furthermore, the light output angles of two standard lenses in the three standard lenses are adjacent to the light output angle adjustment parameter, and the light output angle of the remaining standard lens is smaller than the light output angle of the two standard lenses whose light output angles are adjacent to the light output angle adjustment parameter, and the three standard lenses are standard lenses with three light output angles having adjacent values. The relationship between the third light output angle difference and the first preset angle difference is formed, which facilitates the selection of one of the standard lenses whose light output angle is close to the light output angle adjustment parameter.

[0122] Furthermore, when the third light output angle difference is less than or equal to the first preset angle difference, a third brightness signal is sent to the lighting central controller to adjust the light source output brightness percentage of the lens corresponding to the third preset light output angle.

[0125] It can be understood that the fourth light-emitting angle difference is obtained based on the light-emitting angle adjustment parameter and the fourth preset light-emitting angle. The light-emitting angle adjustment parameter is the light-emitting angle required to be adjusted by the lamp. By collecting the light-emitting angle, it is convenient to determine the light-emitting angle adjustment target of the lamp. The fourth preset light-emitting angle is another of the light-emitting angles of each standard lens, that is, the fourth preset light-emitting angle is the light-emitting angle of the light formed by another standard lens when the corresponding light source brightness percentage is 1. By the difference between the light-emitting angle adjustment parameter and the fourth preset light-emitting angle, it is convenient to determine the difference between the light-emitting angle adjustment parameter and the light-emitting angle of another standard lens. The second preset angle difference is a specified light-emitting angle range, that is, the difference in light-emitting angle between two standard lenses with adjacent light-emitting angles, that is, each of the three compared standard lenses corresponds to a second preset angle difference. By forming a relationship between the fourth light-emitting angle difference and the second preset angle difference, it is convenient to select one of the standard lenses with a light-emitting angle close to the light-emitting angle adjustment parameter, thereby facilitating the adjustment of the light source output brightness of the selected standard lens, so that the light source output of the lamp according to the existing lens is different from or the same as the light-emitting angle of the standard lens.

[0126] Furthermore, when the fourth light output angle difference is less than or equal to the second preset angle difference, a fourth brightness signal is sent to the lighting central controller to adjust the light source output brightness percentage of the lens corresponding to the fourth preset light output angle.

[0127] It can be understood that the second preset angle difference is a specified light-emitting angle range, that is, the difference in the light-emitting angle between two standard lenses with adjacent light-emitting angles. The fourth light-emitting angle difference is less than or equal to the second preset angle difference, indicating that the light-emitting angle adjustment parameter belongs to the specified light-emitting angle range, which is convenient for selecting another lens whose light-emitting angle of the standard lens is close to the light-emitting angle adjustment parameter, thereby facilitating the adjustment of the light source output brightness of the selected standard lens, so that the light-emitting angle of the lamp according to the light source output of the existing lens is different from or the same as the light-emitting angle of the standard lens.

[0128] Furthermore, it is detected whether the fifth light-emitting angle difference is less than or equal to the second preset angle difference.

[0129] It can be understood that the fifth light-emitting angle difference is obtained based on the light-emitting angle adjustment parameter and the fifth preset light-emitting angle. The light-emitting angle adjustment parameter is the light-emitting angle that the lamp needs to adjust. By collecting the light-emitting angle, it is convenient to determine the light-emitting angle adjustment target of the lamp. The fifth preset light-emitting angle is another light-emitting angle of each standard lens. That is, the fifth preset light-emitting angle is the light-emitting angle of light formed by another standard lens when the corresponding light source brightness percentage is 1. By using the difference between the light-emitting angle adjustment parameter and the fifth preset light-emitting angle, it is convenient to determine the difference between the light-emitting angle adjustment parameter and the light-emitting angle of the yet another standard lens. The second preset angle difference specifies a range of light-emitting angles, that is, the difference in light-emitting angles between two standard lenses with adjacent light-emitting angles. That is, each of the three compared standard lenses corresponds to a second preset angle difference. By forming a relationship between the fifth light-emitting angle difference and the second preset angle difference, it is convenient to select another standard lens whose light-emitting angle is close to the light-emitting angle adjustment parameter, thereby facilitating the adjustment of the light source output brightness of the selected standard lens, so that the light-emitting angle of the lamp according to the light source output of the existing lens is different from or the same as that of the standard lens.

[0130] Furthermore, when the fifth light output angle difference is less than or equal to the second preset angle difference, a fifth brightness signal is sent to the lighting central controller to adjust the light source output brightness percentage of the lens corresponding to the fifth preset light output angle.

[0131] It can be understood that the second preset angle difference is a specified light-emitting angle range, that is, the difference in light-emitting angle between two standard lenses with adjacent light-emitting angles. The fifth light-emitting angle difference is less than or equal to the second preset angle difference, indicating that the light-emitting angle adjustment parameter belongs to the specified light-emitting angle range, which is convenient for selecting another lens whose light-emitting angle of the standard lens is close to the light-emitting angle adjustment parameter, thereby facilitating the adjustment of the light source output brightness of the selected standard lens, so that the lamp outputs a light-emitting angle that is different from or the same as that of the standard lens according to the light source output of the existing lens. In this way, the convenient adjustment of the light-emitting angle is achieved through electrical control. The structure only requires at least three lenses and at least three light sources corresponding to each other. It has a simple structure and low preparation cost. It also achieves a light-emitting angle adjustment range that breaks through the limitations of the number of light sources and the number of different lenses, which is conducive to the convenient adjustment of multiple light-emitting angles while reducing costs.

[0132] In one embodiment, after the light output angle adjustment parameter is determined, the relationship between the light source brightness percentage corresponding to the selected standard lens, the third preset light output angle, the fourth preset light output angle, and the fifth preset light output angle is as follows:

[0133] Divide the third preset light output angle (X) to the fifth preset light output angle (Y) into 11 equal parts in sequence, and fill in the angle columns in the table below in sequence. Then, each of the 11 equally divided angles corresponds to a specific brightness percentage, wherein the values of the brightness percentages a, b, and c are the same for any third preset light output angle, fourth preset angle, and fifth preset light output angle, where a is the light source output brightness percentage corresponding to the standard lens selected by the third light output angle difference; b is the light source output brightness percentage corresponding to the standard lens selected by the fourth light output angle difference; and c is the light source output brightness percentage corresponding to the standard lens selected by the fifth light output angle difference, as shown in Table 3 below.

[0138] 1)a=a1+(a2-a1)*[(e-d1) / (d2-d1)]

[0139] Wherein, d1 and d2 are the values of two adjacent groups in the angle column, d2>d1, and d2>e>d1, a1 is the a value corresponding to d1, and a2 is the a value corresponding to d2;

[0140] 2)b=b1+(b2-b1)*[(e-d1) / (d2-d1)]

[0142] 3)c=c1+(c2-c1)*[(e-d1) / (d2-d1)]

[0175] In one embodiment, after the light output angle adjustment parameter is determined, the relationship between the light source brightness percentage corresponding to the selected standard lens, the sixth preset light output angle, the seventh preset light output angle, the eighth preset light output angle, and the ninth preset light output angle is as follows:

[0176] Divide the sixth preset light output angle (X) to the ninth preset light output angle (Y) into 11 equal parts in sequence, and fill in the angle columns in the table below in sequence. Then, the 11 equally divided angles correspond to specific brightness percentages, wherein the values of the brightness percentages a, b, c, and d are the same for any sixth preset light output angle, seventh preset light output angle, eighth preset light output angle, and ninth preset light output angle, wherein a is the percentage of the light source output brightness corresponding to the standard lens selected by the sixth light output angle difference; b is the percentage of the light source output brightness corresponding to the standard lens selected by the seventh preset light output angle; c is the percentage of the light source output brightness corresponding to the standard lens selected by the eighth light output angle difference; d is the percentage of the light source output brightness corresponding to the standard lens selected by the ninth preset light output angle, as shown in Table 5 below.

[0177] Table 5

[0178]

[0179] When the light output angle adjustment parameter (f) is the same as the value in the angle column in Table 5, that is, when f=e, the corresponding output directly corresponds to the light source output brightness percentage a corresponding to the standard lens selected by the sixth light output angle difference, the light source output brightness percentage b corresponding to the standard lens selected by the seventh light output angle difference, the light source output brightness percentage c corresponding to the standard lens selected by the eighth light output angle difference, and the light source output brightness percentage d corresponding to the standard lens selected by the ninth light output angle difference;

[0180] When the light output angle adjustment parameter (f) is different from the value in the angle column of Table 1, the light source output brightness percentage a corresponding to the standard lens selected by the sixth light output angle difference, the light source output brightness percentage b corresponding to the standard lens selected by the seventh light output angle difference, the light source output brightness percentage c corresponding to the standard lens selected by the eighth light output angle difference, and the light source output brightness percentage c corresponding to the standard lens selected by the ninth light output angle difference satisfy the following relationship:

[0181] 1)a=a1+(a2-a1)*[(f-e1) / (e2-e1)]

[0182] Wherein, e1 and e2 are the values of two adjacent groups of values in the angle column, e2>e1, and e2>f>e1, a1 is the a value corresponding to e1, and a2 is the a value corresponding to e2;

[0183] 2)b=b1+(b2-b1)*[(f-e1) / (e2-e1)]

[0184] Wherein, e1 and e2 are the values of two adjacent groups in the angle column, e2>e1, and e2>f>e1, b1 is the b value corresponding to e1, and b2 is the b value corresponding to e2;

[0185] 3)c=c1+(c2-c1)*[(f-e1) / (e2-e1)]

[0186] Wherein, e1 and e2 are the values of two adjacent groups in the angle column, e2>e1, and e2>f>e1, c1 is the c value corresponding to e1, and c2 is the c value corresponding to e2;

[0187] 4)d=d1+(d2-d1)*[(f-e1) / (e2-e1)]

[0188] Wherein, e1 and e2 are the values of two adjacent groups in the angle column, e2>e1, and e2>f>e1, d1 is the d value corresponding to e1, and d2 is the d value corresponding to e2;

[0189] In particular, when the sixth preset light output angle is 6°, the seventh preset light output angle is 10°, the eighth preset light output angle is 15°, and the ninth preset light output angle is 24°, the data in Table 6 are obtained by substituting Table 5 into Table 6, as shown in Table 6:

[0190] Table 6

[0191]

[0192] When the light output angle adjustment parameter is 16, the light source output brightness percentage a corresponding to the standard lens selected by the sixth light output angle difference is calculated as a=a1+(a2-a1)*[(f-e1) / (e2-e1)] to be 0.27; the light source output brightness percentage b corresponding to the standard lens selected by the seventh light output angle difference is calculated as b=b1+(b2-b1)*[(f-e1) / (e2-e1)] to be 0.22; the light source output brightness percentage c corresponding to the standard lens selected by the eighth light output angle difference is calculated as c1+(c2-c1)*[(f-e1) / (e2-e1)] to be 0.14; the light source output brightness percentage d corresponding to the standard lens selected by the ninth light output angle difference is calculated as 0.38;

[0193] When the light output angle adjustment parameter is 23, the light source output brightness percentage a corresponding to the standard lens selected by the sixth light output angle difference is calculated as 0.02 by a=a1+(a2-a1)*[(f-e1) / (e2-e1)]; the light source output brightness percentage b corresponding to the standard lens selected by the seventh light output angle difference is calculated as 0.01 by b=b1+(b2-b1)*[(f-e1) / (e2-e1)]; the light source output brightness percentage c corresponding to the standard lens selected by the eighth light output angle difference is calculated as 0.01; and the light source output brightness percentage d corresponding to the standard lens selected by the ninth light output angle difference is calculated as 0.96.

[0194] It should be noted that the angle adjustment difference processing is to obtain the difference between the light-emitting angle adjustment parameter and the preset light-emitting angle, and the difference is an absolute value, that is, the light-emitting angle difference is a positive number greater than or equal to 0, that is, the first light-emitting angle difference, the second light-emitting angle difference, the sixth light-emitting angle difference, the fourth light-emitting angle difference, the fifth light-emitting angle difference, the sixth light-emitting angle difference and the seventh light-emitting angle difference are all positive numbers greater than or equal to 0.

[0195] It should also be noted that, by adjusting the brightness of the four lenses and the corresponding light sources, it is feasible to output light with a light-emitting angle that is different from the light formed when the brightness percentage of the light sources corresponding to the four lenses with the selected adjacent light-emitting angle adjustment parameters is 1, that is, the light-emitting angle of the output light is different from the light-emitting angle of the light formed when the brightness percentage of the light source corresponding to any selected lens is 1. In this application, the number of different lenses is not limited, and the number of light sources for brightness adjustment is not limited. It only protects the light-emitting angle of the output light that is different from the light-emitting angle of the light formed when the brightness percentage of the light source corresponding to any selected lens is 1 by adjusting the brightness of at least two light sources to cooperate with the corresponding lenses.

[0196] It should also be noted that the light sources corresponding to the standard lenses are all point light sources.

[0197] It should also be noted that selecting five or more groups of standard lenses to adjust the brightness percentage of the corresponding lenses can also achieve adjustment of light output angles that are different from those of each standard lens. The specific rules can refer to the cases of two groups of standard lenses, three groups of standard lenses, and four groups of standard lenses to adjust the brightness percentage of the light source corresponding to the selected standard lenses. This will not be further described below.

[0198] The present application also provides an optical structure for executing the electric control method of the light output angle of any of the above embodiments. In order to better understand the optical structure of the present application, the optical structure of the present application is further explained below. Please refer to Figures 2 to 4The optical structure of one embodiment includes at least two light source components 100 and at least two optical components 200; each light source component 100 is respectively arranged corresponding to one optical component 200; the light emitted by each light source component 100 is incident on the corresponding optical component 200 and is emitted at the corresponding split-mirror beam angle through the corresponding optical component 200; when the light emitted by at least any two light source components 100 is incident on the corresponding optical component 200, each light passes through the corresponding optical component 200 to form a light emitted at a combined beam angle; each light source component 100 is configured to emit light with variable brightness, so that the combined beam angle is different from the beam angles of each split mirror.

[0199] It can be understood that since each light source element 100 is respectively arranged in correspondence with an optical element 200, the light emitted by each light source element 100 can be emitted through the corresponding optical element 200 at the corresponding split-mirror beam angle after entering the corresponding optical element 200. In this case, the light emitted by at least any two light sources 100, after passing through the corresponding optical element 200, together forms light emitted at the combined mirror beam angle. Compared with the prior art, by configuring each light source element 100 to emit light with variable brightness, the brightness of the light emitted by at least any two light sources 100 can be adjusted, thereby making the combined mirror beam angle different from the beam angles of each split mirror, thereby achieving more flexible adjustment of the light output angle. This does not require increasing the types of light sources 100 or optical elements 200, and is more convenient to use.

[0200] In some embodiments, the split-mirror beam angle is the light emitting angle when each light source element 100 is fully lit and is emitted through the corresponding optical element 200. The light emitting angles of different light source elements 100 when they are fully lit and are emitted through the corresponding optical element 200 are different, that is, the light emitting angle of the light emitted by the corresponding optical element 200 when the brightness percentage of the light source element 100 is 1, and the number of groups of optical elements 200 and corresponding light source elements 100 is at least two, that is, the combined beam angle is the light emitting angle of the light after the light emitted through the corresponding optical element 200 when at least two of the light source elements 100 are not fully lit overlaps, that is, the combined beam angle is the light emitting angle obtained after the light emitted through the corresponding optical element when the brightness percentage of at least one light source element 100 is less than 1 overlaps with the light emitted through the corresponding optical element of at least one other light source element 100. For ease of understanding, for example, when the number of groups of optical components 200 and corresponding light source components 100 is two, the light emitting angle of the light when the first light source component is fully lit and emitted through the corresponding first optical component is 6 degrees, and the light emitting angle of the light when the second light source component is fully lit and emitted through the corresponding second optical component is 10 degrees. By reducing the brightness of the second light source component, the light emitting angle of the light after the light emitted by the second optical component overlaps with the light emitted by the first optical component 200 can be 8 degrees.

[0201] It can be understood that the preset light output angle parameter is the split-mirror beam angle of the light emitted by each optical component when the brightness percentage of the corresponding light source component is 1, that is, the optical component is a standard lens.

[0202] See also Figure 2 In some embodiments, the beam angles of any two mirrors are different. It is understood that because the beam angles of any two mirrors are different, the beam angles of the light emitted by the light source component 100 through different optical components 200 are different. In this way, each light can emit at least two light beams with different beam angles through the corresponding optical component 200. The at least two light beams with different beam angles can be combined to form light emitted at a combined beam angle. Then, by adjusting the brightness of the light emitted by the corresponding two light source components 100, the combined beam angle can be made different from the beam angles of each mirror, thereby achieving more flexible adjustment of the light output angle.

[0203] See also Figure 2 In some embodiments, the split-mirror beam angle of the optical element 200 is between 4 and 60 degrees. It will be appreciated that because the split-mirror beam angle of the optical element 200 is between 4 and 60 degrees, light passing through the optical element 200 with at least two different light-emitting angles between 4 and 60 degrees can collectively simulate light emitted at a combined beam angle. Specifically, the optical elements 200 with different light-emitting angles between 4 and 60 degrees can form light emitted at a combined beam angle, i.e., a lamp with a light effect intermediate between the two light effects can be obtained by using light with two different light effects.

[0204] See also Figure 2 In this embodiment, the light output angle of the optical element 200 is selected from at least two intervals of greater than or equal to 4 degrees and less than 8 degrees, greater than or equal to 8 degrees and less than 13 degrees, greater than or equal to 13 degrees and less than 20 degrees, greater than or equal to 20 degrees and less than 29 degrees, greater than or equal to 29 degrees and less than 42 degrees, and greater than or equal to 42 degrees and less than 60 degrees, and is specifically not limited to the following selection methods:

[0205] In one embodiment, the light emitting angle of one optical element 200 is greater than or equal to 4 degrees and less than 8 degrees, and the light emitting angle of the other optical element 200 is greater than or equal to 8 degrees and less than 13 degrees. It can be understood that when the light emitting angle of one optical element 200 is greater than or equal to 4 degrees and less than 8 degrees, and the light emitting angle of the other optical element 200 is greater than or equal to 8 degrees and less than 13 degrees, the light emitting effect of the optical element 200 with a light emitting angle of approximately 8 degrees can be simulated by the above two optical elements 200. For example, if the light emitting angle of one optical element 200 is 6 degrees and the light emitting angle of the other optical element 200 is 10 degrees, the light emitting effect of the optical element 200 with a light emitting angle of 8 degrees can be simulated by the above two optical elements 200 and adjusting the brightness of the corresponding light source element 100.

[0206] In another embodiment, the light emitting angle of one optical element 200 is greater than or equal to 13 degrees and less than 20 degrees, and the light emitting angle of the other optical element 200 is greater than or equal to 20 degrees and less than 29 degrees. It can be understood that when the light emitting angle of one optical element 200 is greater than or equal to 13 degrees and less than 20 degrees, and the light emitting angle of the other optical element 200 is greater than or equal to 20 degrees and less than 29 degrees, the light emitting effect of the optical element 200 with a light emitting angle of approximately 20 degrees can be simulated by the above two optical elements 200. For example, if the light emitting angle of one optical element 200 is 16 degrees and the light emitting angle of the other optical element 200 is 24 degrees, the light emitting effect of the optical element 200 with a light emitting angle of 20 degrees can be simulated by the above two optical elements 200 and adjusting the brightness of the corresponding light source element 100.

[0207] In other embodiments, the light emitting angle of one optical element 200 is greater than or equal to 29 degrees and less than 42 degrees, and the light emitting angle of the other optical element 200 is greater than or equal to 42 degrees and less than 60 degrees. It can be understood that when the light emitting angle of one optical element 200 is greater than or equal to 29 degrees and less than 42 degrees, and the light emitting angle of the other optical element 200 is greater than or equal to 42 degrees and less than 60 degrees, the light emitting effect of the optical element 200 with a light emitting angle of approximately 42 degrees can be simulated by the above two optical elements 200. For example, if the light emitting angle of one optical element 200 is 41 degrees and the light emitting angle of the other optical element 200 is 47 degrees, the light emitting effect of the optical element 200 with a light emitting angle of 44 degrees can be simulated by the above two optical elements 200 and adjusting the brightness of the corresponding light source element 100.

[0208] In some embodiments, the light emitting angles of different optical components 200 differ by 4 to 8 degrees. It is understood that by making the light emitting angles of different optical components 200 differ by 4 to 8 degrees, it is possible to maintain an appropriate gap between the light emitting angles of different optical components 200, so that light with a predetermined combined beam angle can be obtained more quickly by subsequently adjusting the brightness of the corresponding light source component 100, while ensuring the adjustable range of the combined beam angle. Specifically, the light emitting angles of different optical components 200 differ by 4, 6, or 8 degrees. Of course, this is only for illustration and does not limit the present disclosure.

[0209] See also Figure 2In this embodiment, the optical component 200 is a lens, and the light emission angles of the lens are different, such as 6 degrees, 8 degrees, 10 degrees, 15 degrees, 24 degrees, 35 degrees, and 60 degrees. Lenses with the same light emission angle are grouped together, and the light emission effect of a lens with a light emission angle located between the two adjacent lenses with different light emission angles can be simulated by lighting the light source components 100 corresponding to two adjacent lenses with different light emission angles. For example, by controlling the light source component 100 corresponding to the lens with a light emission angle of 6 degrees and the light source component 100 corresponding to the lens with a light emission angle of 10 degrees, the light emission effect of a lens with a light emission angle of 8 degrees can be obtained. In this embodiment, the lenses are integrally connected to form a sheet structure, and the light source components 100 are lamp beads.

[0210] In some embodiments, the maximum spacing between two light source elements 100 is 90 mm. It will be understood that since the maximum spacing between the two light source elements 100 is 90 mm, that is, the spacing between any two light source elements 100 is less than or equal to 90 mm, the light emitted by any two light source elements 100 can at least partially overlap, thereby forming light emitted at a combined beam angle.

[0211] See also Figure 2 In some embodiments, the optical structure further includes an intelligent driver 300, which is electrically connected to the light source components 100 with the same light output angle through the same circuit. It can be understood that since the intelligent driver 300 is electrically connected to the light source components 100 with the same light output angle through the same circuit, the brightness of each light source component 100 with the same light output angle can be adjusted by the intelligent driver 300, thereby making the combined mirror beam angle different from the split mirror beam angle, so as to achieve more flexible adjustment of the light output angle. Specifically, the intelligent driver 300 is a variable resistor that can change the voltage of each circuit to achieve adjustment of the brightness of the light source component 100 and even turn it on and off.

[0212] See also Figure 2 and Figure 3 In this embodiment, the optical structure further includes a light source board 400, on which each light source element 100 is mounted. Light source elements 100 with the same light output angle are connected to the same circuit on the light source board 400, and the intelligent driver 300 is electrically connected to each circuit on the light source board 400. For example, if the light source elements 100 include three different light sources 100, the intelligent driver 300 can electrically illuminate two or more light sources 100 simultaneously. The brightness of the illuminated light sources 100 can then be adjusted to project light at a combined beam angle.

[0213] In some embodiments, each light source component 100 includes multiple light-emitting components; each optical component 200 includes multiple lenses, and the multiple light-emitting components are arranged in a one-to-one correspondence with the multiple lenses. The light emitted by any number of light-emitting components of each light source component 100 enters the corresponding lens and is emitted through the corresponding lens at the corresponding split-mirror beam angle; when the light emitted by any number of light-emitting components of at least any two light source components 100 enters the corresponding lens, each light passes through the corresponding lens to form a light emitted at a combined beam angle; each light-emitting component of each light source component 100 is configured to emit light with variable brightness, so that the combined beam angle is different from the beam angles of each split mirror. It can be understood that since the light-emitting elements in each optical element 200 are respectively arranged in a one-to-one correspondence with each lens, the light emitted by any number of light-emitting elements of each light source element 100 can be emitted through the corresponding lens at the corresponding split-mirror beam angle after entering the corresponding lens. At this time, the light emitted by any number of light-emitting elements of at least any two light source elements 100 together constitutes the light emitted at the combined mirror beam angle after passing through the corresponding lens. Moreover, by configuring each light-emitting element of each light source element 100 to emit light with variable brightness, the brightness of the light emitted by any number of light-emitting elements of at least any two light source elements 100 can be adjusted, so that the combined mirror beam angle and the split-mirror beam angle are different, so as to achieve more flexible adjustment of the light output angle, and there is no need to increase the types of light source elements 100 or optical elements 200, which is more convenient to use.

[0214] It should be noted that, in a specific embodiment, the plurality of light-emitting elements may be two or more light-emitting elements, specifically two light-emitting elements, three light-emitting elements, four light-emitting elements, etc., and the number of light-emitting elements in different light-emitting elements 100 may be the same or different. This is, of course, merely an example and not a limitation on the specific embodiment. Those skilled in the art may determine the number of light-emitting elements as needed. Furthermore, in a specific embodiment, the arbitrary number of light-emitting elements may be at least one, two, more than two, or all light-emitting elements. In some implementations, light emitted by different numbers of light-emitting elements in different light-emitting elements 100 may be incident upon corresponding lenses, or light emitted by the same number of light-emitting elements in different light-emitting elements 100 may be incident upon corresponding lenses. This is, of course, merely an example and not a limitation on the specific embodiment.

[0215] In order to achieve the effect of accent lighting, the arrangement of the multiple light-emitting elements of any two light source elements 100 is not limited to the following:

[0216] In one embodiment, the multiple light-emitting elements of any two light-emitting elements 100 are coaxially arranged. It is understood that after the multiple light-emitting elements of any two light-emitting elements 100 are coaxially arranged, the light energy emitted by each light-emitting element 100 is evenly distributed, so that the light energy emitted by any number of light-emitting elements of at least any two light-emitting elements 100 that are misaligned can be more easily combined into light emitted at a combined beam angle after passing through corresponding lenses.

[0217] In one embodiment, the multiple light-emitting elements of any two light source components 100 are arranged circumferentially, and each light-emitting element of one light source component 100 is offset from each light-emitting element of the other light source component 100. It will be appreciated that after the multiple light-emitting elements of any two light source components 100 are arranged circumferentially, light energy emitted by any number of the offset light-emitting elements of at least any two light source components 100 can more easily be combined into light emitted at a combined beam angle after passing through corresponding lenses.

[0218] In one embodiment, the multiple light-emitting elements of any two light source components 100 are arranged in a circular array, with each light-emitting element of one light source component 100 offset from each light-emitting element of the other light source component 100. It will be appreciated that after the multiple light-emitting elements of any two light source components 100 are arranged in a circular array, light energy emitted by any number of the offset light-emitting elements of at least any two light source components 100 can be combined into light emitted at a combined beam angle after passing through corresponding lenses, and the light emitted at the combined beam angle at each position has a uniform luminous effect.

[0219] In one embodiment, the multiple light-emitting elements of any two light-source components 100 are arranged in a circular array, and the multiple light-emitting elements of each light-source component 100 are evenly arranged, and each light-emitting element of each light-source component 100 is offset from each light-emitting element of the other light-source component 100. It will be understood that after the multiple light-emitting elements of any two light-source components 100 are arranged in a circular array, and the multiple light-emitting elements of each light-source component 100 are evenly arranged, the light energy emitted by any number of the offset light-emitting elements of at least any two light-source components 100 can form light emitted at a combined beam angle after passing through corresponding lenses, and the light efficiency of the light emitted at the combined beam angle at each position is uniform.

[0220] In one embodiment, the multiple light-emitting elements of each light source unit 100 are arranged circumferentially, and the circumferential arrangement radius of the multiple light-emitting elements of one light source unit 100 is different from the circumferential arrangement radius of the multiple light-emitting elements of another light source unit 100. It can be understood that by making the circumferential arrangement radius of the multiple light-emitting elements of one light source unit 100 different from the circumferential arrangement radius of the multiple light-emitting elements of another light source unit 100, for example, by making the circumferential arrangement radius of the multiple light-emitting elements of one light source unit 100 larger than the circumferential arrangement radius of the multiple light-emitting elements of another light source unit 100, the multiple light-emitting elements of different light sources 100 can be staggered and concentrically arranged, so that the light emitted by each light source unit 100 can be more concentrated, thereby achieving a focused lighting effect.

[0221] In one embodiment, the multiple light-emitting elements of each light source element 100 are arranged in a circular array, and the circumferential arrangement radius of the multiple light-emitting elements of one light source element 100 is different from the circumferential arrangement radius of the multiple light-emitting elements of another light source element 100. It can be understood that by making the circumferential arrangement radius of the multiple light-emitting elements of one light source element 100 different from the circumferential arrangement radius of the multiple light-emitting elements of another light source element 100, for example, by making the circumferential arrangement radius of the multiple light-emitting elements of one light source element 100 smaller than the circumferential arrangement radius of the multiple light-emitting elements of another light source element 100, the multiple light-emitting elements of different light sources 100 can be staggered and concentrically arranged, thereby making the light emitted by each light source element 100 more concentrated, thereby achieving a focused lighting effect. Furthermore, because the multiple light-emitting elements of each light source element 100 are arranged in a circular array, the light emitted by each light source element 100 can be more evenly distributed.

[0222] It should be noted that when there are multiple light source components, the arrangement of the multiple light emitting components of the above-mentioned different light source components can exist in the same embodiment at the same time, and the details will not be repeated here. In this embodiment, the light emitting components are lamp beads.

[0223] See also Figure 2 and Figure 4 In this embodiment, the optical structure further includes a heat sink 500 , which is mounted on the back of the light source board 400 to dissipate heat for each light source element 100 .

[0224] See also Figure 2 and Figure 4In some embodiments, the light source component 100 includes at least two light-emitting bodies, and the light-emitting angles of any two light-emitting bodies are different. It can be understood that since the light source component 100 includes at least two light-emitting bodies, and the light-emitting angles of any two light-emitting bodies are different, the light beam angles of the light emitted by the light source components 100 having different light-emitting bodies through the optical component 200 are different, so that each light can emit at least two lights with different beam angles through the corresponding optical component 200, and at least two lights with different beam angles can form light emitted at a combined beam angle, and then the brightness of the light emitted by the corresponding at least any two light source components 100 can be adjusted, so that the combined beam angle and the split beam angle are different, so as to achieve more flexible adjustment of the light-emitting angle. Among them, the light-emitting body can be an LED lamp bead or a projection light source, of course, this is not limited here, and those skilled in the art can also make other choices according to needs.

[0225] See also Figure 3 In some embodiments, the light source components 100 with the same light emission angle form a group, and the corresponding two light source components 100 in the same group are symmetrically distributed in pairs, and the symmetry center of each group of light source components 100 is the same. It can be understood that since the corresponding two light source components 100 in the same group are symmetrically distributed in pairs, and the symmetry center of each group of light source components 100 is the same, the light emitted by the light source components 100 can be made more concentrated, thereby achieving the effect of accent lighting. Specifically, the two light source components 100 in the same group are centrally symmetrically distributed in pairs, and the light source components 100 in each group are distributed in a ring shape around the same symmetry center. In this embodiment, the light source components 100 with a light emission angle of a first angle form a first light source group 101, the light source components 100 with a light emission angle of a second angle form a second light source group 102, and the light source components 100 with a light emission angle of a third angle form a third light source group 103.

[0226] This application also provides a lighting device, including the optical structure of any of the above embodiments. Figures 2 to 4 In this embodiment, the optical structure includes at least two light source elements 100 and at least two optical elements 200; each light source element 100 is respectively arranged corresponding to one optical element 200; light emitted by each light source element 100 enters the corresponding optical element 200 and is emitted at the corresponding split-mirror beam angle through the corresponding optical element 200; when light emitted by at least any two light source elements 100 enters the corresponding optical element 200, each light passes through the corresponding optical element 200 to form light emitted at a combined beam angle; each light source element 100 is configured to emit light with variable brightness, so that the combined beam angle is different from the beam angles of each split mirror.

[0227] The above-mentioned lighting device, by applying an optical structure in the lighting device, can adjust the brightness of the light emitted by at least any two corresponding light source components, thereby making the combined mirror beam angle different from the beam angle of each separate mirror, so as to achieve more flexible adjustment of the light output angle, and there is no need to increase the types of light sources or optical components, which is more convenient to use.

[0228] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
