[0027] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the present invention.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] The luminous angles required by lamps in different applications are different. The divergence angle of the light beam of lamps in related technologies is single, and the lighting angle of the lamps is single. Some lamps replace the light source module to adapt to the luminous angles required by lamps in different applications. However, the method of adjusting the divergence angle of the light beam of lamps is complicated.

[0030] Please also refer to Figures 1 to 3The present invention provides a lamp 100, which can be a lamp tube, a wall washer, etc. The lamp 100 includes a shell 11 and a plurality of light source modules 12. The light source module 12 is assembled on the shell 11. Each light source module 12 includes an LED light-emitting chip 121 and a focusing lens 122. The LED light-emitting chip 121 can be a light source using white light, RGB color light, RGBWW or other forms, which can be specifically set according to actual conditions. The focusing lens 122 is located in the light output path of the LED light-emitting chip 121. In this way, the focusing lens 122 can focus the output light of the LED light-emitting chip 121 and then emit it, which helps to concentrate the output light of the light source module 12 and helps to improve the light intensity of the light source module 12.

[0031] Among them, the LED light-emitting chip 121 of each light source module 12 is independently controlled, and the emitted light of the LED light-emitting chip 121 of each light source module 12 is irradiated to the outside of the shell 11 through the focusing lens 122 to form an output light beam. The divergence angles of the output light beams of at least two light source modules 12 are different.

[0032] Among them, phase difference means that the directions of the divergence angles of the light beams of multiple light source modules 12 are different, and / or the angles of the divergence angles of the light beams of multiple light source modules 12 are different; independent control means that the LED light-emitting chip 121 of each light source module 12 is controlled by different devices, for example, the LED light-emitting chips 121 of multiple light source modules 12 are controlled by corresponding control components, so that the light source module 12 can control the light emission of the LED light-emitting chip 121 of the light source module 12 by controlling the corresponding control components, and the light emission of the LED light-emitting chips 121 of different light source modules 12 does not affect each other.

[0033] In this way, by controlling a single or multiple light source modules 12 to emit light, the lamp 100 can selectively emit light beams with different divergence angles, thereby helping to achieve one lamp with multiple angles for the lamp 100, helping to meet the angle usage requirements of the lamp 100 in different scenes, and also helping to improve the flexibility of the lamp 100 and facilitate the regulation of the lamp 100.

[0034] Here, a plurality refers to two or more than two. For example, the lamp 100 may include two, three, four or other numbers of light source modules 12 , which can be specifically configured according to actual conditions.

[0035] For example, Figure 4 and Figure 5As shown, the lamp 100 may include a first light source module 13 and a second light source module 14, which are assembled side by side on the shell 11, and the divergence angle of the light beam of the first light source module 13 is α, and the divergence angle of the light beam of the second light source module 114 is β. The control components corresponding to the LED light-emitting chips 121 of the first light source module 13 and the second light source module 14 can be used to control the LED light-emitting chips 121 of the first light source module 13 and the second light source module 14 to emit light, so that the LED light-emitting chips 121 of the first light source module 13 and the second light source module 14 both emit light, so that the divergence angle α of the light beam of the first light source module 13 and the divergence angle β of the light beam of the second light source module 14 are different, so that the lamp 100 can emit at least two light beams with different divergence angles. For example, the divergence angle α of the light beam of the first light source module 13 can be 30°, and the divergence angle β of the light beam of the second light source module 14 can be 80°. The specific settings can be made according to actual conditions. Among them, the dotted line in the figure is the output light of the light source module 12.

[0036] For example, Figure 6 As shown, the control component corresponding to the LED light-emitting chip 121 of the first light source module 13 can control the LED light-emitting chip 121 of the first light source module 13 to emit light, so that the LED light-emitting chip 121 of the first light source module 13 emits light, and thus the lamp 100 can emit a light beam. The specific setting can be based on actual conditions. Among them, the dotted line in the figure represents the output light of the light source module 12.

[0037] In this way, by controlling the light emission of a single or multiple light source modules 12 separately, the lamp 100 can selectively emit light beams with different divergence angles, which helps to meet the angle usage requirements of the lamp 100 in different scenes, and also helps to improve the flexibility of the adjustment of the lamp 100 and facilitate the regulation of the lamp 100.

[0038] Re-read Figure 2 In some embodiments, the focusing lenses 122 of the multiple light source modules 12 are assembled side by side on the housing 11, and the light emitting surfaces 1211 of the LED light emitting chips 121 of the multiple light source modules 12 face the same direction.

[0039] In this way, the LED light-emitting chips 121 of multiple light source modules 12 can emit light toward the same side, which helps to improve the brightness of the light emitted by the lamp 100, and also allows the lamp 100 to arrange the light source modules 12 from the same side, which also helps to facilitate the maintenance and replacement of the light source modules 12 from the same side of the lamp 100.

[0040] In some embodiments, the minimum distance between the light emitting surface 1211 of the LED light emitting chip 121 and the focusing lens 122 in the same light source module 12 is different from the minimum distance between the light emitting surface 1211 of the LED light emitting chip 121 and the focusing lens 122 in another light source module 12.

[0041] In this way, the light emitted by the LED light emitting chips 121 in the multiple light source modules 12 can enter the condenser lens 122 in the corresponding light source module 12 at different incident angles, thereby making the divergence angles of the light beams emitted by different light source modules 12 different.

[0042] In addition, since the focusing lenses 122 of multiple light source modules 12 are assembled side by side on the shell 11, the lamp 100 only needs to arrange the positions of the light-emitting surfaces 1211 of the LED light-emitting chips 121 in the multiple light source modules 12, which helps to simplify the design of the lamp 100 and facilitate manufacturing.

[0043] In some embodiments, the curvature radius of the light-emitting surface 1221 of the focusing lenses 122 of multiple light source modules 12 can be the same, so that the lamp 100 can use the focusing lenses 122 of the same specification, which helps to facilitate the assembly of the lamp 100 and also helps to facilitate the replacement of the focusing lenses 122 between different light source modules 12; or, the curvature radius of the light-emitting surface 1221 of the focusing lenses 122 of multiple light source modules 12 is different, so as to better distinguish the divergence angles of the light beams of different light source modules 12. The specific setting can be made according to actual conditions.

[0044] See Figure 7 In some embodiments, the first light source module 13 and the second light source module 14 both include an LED light-emitting chip 121 and a focusing lens 122, the minimum distance X1 between the light-emitting surface 1211 of the LED light-emitting chip 121 of the first light source module 13 and the focusing lens 122 is greater than the minimum distance X2 between the light-emitting surface 1211 of the LED light-emitting chip 121 of the second light source module 14 and the focusing lens 122, and the curvature radius of the light-emitting surface 1221 of the focusing lens 122 of the second light source module 14 is greater than the curvature radius of the light-emitting surface 1221 of the focusing lens 122 of the first light source module 13.

[0045] This helps increase the divergence angle of the light beam emitted by the second light source module 14 , thereby increasing the difference in divergence angles between the first light source module 13 and the second light source module 14 , and also helps increase the illumination range of the lamp 100 .

[0046] Among them, such as Figure 3As shown, when the curvature radius of the light emitting surface 1221 of the focusing lens 122 of the second light source module 14 is the same as the curvature radius of the light emitting surface 1221 of the focusing lens 122 of the first light source module 13, and the minimum distance X1 between the light emitting surface 1211 of the LED light emitting chip 121 of the first light source module 13 and the focusing lens 122 is greater than the minimum distance X2 between the light emitting surface 1211 of the LED light emitting chip 121 of the second light source module 14 and the focusing lens 122, β=3(X1-X2)+30°.

[0047] In some embodiments, each light source module 12 further includes a light mixing element 123, which is located in the light output path of the LED light emitting chip 121 and is adapted to guide the output light of the LED light emitting chip 121 to the focusing lens 122. The light mixing element 123 may be a milky white light mixing cover.

[0048] In this way, the light mixing element 123 helps to diverge the light emitted by the LED light emitting chip 121 to better mix the light emitted by the LED light emitting chip 121, which helps to improve the uniformity of light mixing of the light source module 12, thereby helping to reduce glare generated by the lamp 100.

[0049] In some embodiments, the curvature radius of the light-emitting surface 1221 of the condenser lens 122 is 30 mm to 60 mm.

[0050] In this way, it helps to ensure that the light-emitting surface 1221 of the focusing lens 122 has a suitable radius of curvature, helps to ensure that the focusing lens 122 has sufficient focusing ability, helps to reduce the situation where the radius of curvature of the light-emitting surface 1221 of the focusing lens 122 is too large, helps to reduce the situation where the focusing ability of the focusing lens 122 is too strong, resulting in excessive concentration of light, also helps to reduce the situation where the radius of curvature of the focusing lens 122 is too small, and helps to reduce the situation where the focusing ability of the focusing lens 122 is insufficient, resulting in uneven light distribution and poor lighting effect.

[0051] Exemplarily, the curvature radius of the light-emitting surface 1221 of the focusing lens 122 can be 30 mm, 35 mm, 40 mm, 45 mm, 48 mm, 50 mm, 55 mm, 60 mm or other values, which can be set according to actual conditions.

[0052] This helps ensure that the condensing lens 122 has sufficient condensing capability, helps the condensing lens 122 better focus the light emitted by the LED light emitting chip 121 , and thus helps improve the light emitting effect of the light source module 12 .

[0053] See also Figure 8 In some embodiments, the divergence angles of the light beams emitted by at least three light source modules 12 are different.

[0054] In this way, the lamp 100 can selectively emit light beams with different divergence angles, so that the lamp 100 can have more variable angles, which helps to better realize the one-lamp-multiple-angle function of the lamp 100, helps to better meet the angle usage requirements of the lamp 100 in different scenarios, and also helps to improve the flexibility of the adjustment of the lamp 100, making it easier to control the lamp 100.

[0055] For example, the plurality of light source modules 12 may include a first light source module 13, a second light source module 14, and a third light source module 15, the first light source module 13, the second light source module 14, and the third light source module 15 are assembled side by side in the housing 11, and the divergence angles of the light beams emitted by the first light source module 13, the second light source module 14, and the third light source module 15 are all different. For another example, the plurality of light source modules 12 may include a first light source module 13, the second light source module 14, the third light source module 15, and a fourth light source module 12, the first light source module 13, the second light source module 14, the third light source module 15, and the fourth light source module 12 are assembled side by side in the housing 11, and the divergence angles of at least three light source modules 12 among the first light source module 13, the second light source module 14, the third light source module 15, and the fourth light source module 12 are different. The specific setting can be made according to actual conditions.

[0056] In this way, by controlling the light emission of a single or multiple light source modules 12 , the lamp 100 can selectively emit light beams with different divergence angles, thereby helping to meet the angle usage requirements of the lamp 100 in different scenarios.

[0057] In some embodiments, a plurality of light source modules 12 are assembled side by side in the housing 11 , and the divergence angles of the emitted light beams increase or decrease sequentially along the direction in which the plurality of light source modules 12 are arranged side by side.

[0058] In this way, the divergence angles of the light beams of multiple light source modules 12 can be arranged regularly, which helps to distinguish the positions of light source modules 12 with different divergence angles of light beams, and helps to more accurately control the light emission of the corresponding light source modules 12 to better meet the angle usage requirements of the lamp 100 in the corresponding scene.

[0059] For example, Figure 8 As shown, multiple light source modules 12 are mounted side by side on the housing 11, and the divergence angle of the light beam decreases in sequence along the direction in which the multiple light source modules 12 are arranged, such as the horizontal direction. When the usage scenario requires large-angle lighting, the light source module 12 on the left can be controlled to emit light so that the lamp 100 can emit a light beam with a larger divergence angle to meet the requirement. When the usage scenario requires small-angle lighting, the light source module 12 on the right can be controlled to emit light so that the lamp 100 can emit a light beam with a smaller divergence angle to meet the requirement.

[0060] For example, Figure 9 As shown, multiple light source modules 12 are mounted side by side on the housing 11, and the divergence angle of the light beam increases sequentially along the direction in which the multiple light source modules 12 are arranged side by side, such as the horizontal direction. When the usage scenario requires small-angle lighting, the light source module 12 on the left can be controlled to emit light, so that the lamp 100 can emit a light beam with a smaller divergence angle to meet the requirement. When the usage scenario requires large-angle lighting, the light source module 12 on the right can be controlled to emit light, so that the lamp 100 can emit a light beam with a larger divergence angle to meet the requirement.

[0061] Re-read Figure 2 and Figure 3 In some embodiments, the housing 11 includes a light shielding portion 111 , which separates the LED light emitting chips 121 of two adjacent light source modules 12 , and the light shielding portion 111 separates the focusing lenses 122 of two adjacent light source modules 12 .

[0062] This helps reduce the mutual interference between the emitted light of two adjacent light source modules 12, thereby helping to ensure normal light emission between the two adjacent light source modules 12, and also helps reduce the situation where the emitted light of one light source module 12 escapes to another light source module 12, thereby helping to improve the utilization rate of the emitted light of the light source module 12 and helping to reduce the loss of light energy.

[0063] The housing 11 may be made of a material such as silicone or rubber to protect the plurality of light source modules 12.

[0064] In some embodiments, the housing 11 is provided with a weight-reducing portion 112 , and the weight-reducing portion 112 avoids the focusing lenses 122 of the plurality of light source modules 12 .

[0065] This helps reduce the weight of the lamp 100 , helps save manufacturing costs, and helps reduce the situation where the output light of multiple light source modules 12 escapes from the weight-reducing portion 112 , thereby helping to improve the utilization rate of the output light of the light source module 12 .

[0066] In summary, the lamp 100 provided by the present invention has a light source module 12 assembled on a housing 11, and each light source module 12 includes an LED light-emitting chip 121 and a focusing lens 122, and the focusing lens 122 is located on the light-emitting path of the LED light-emitting chip 121. The LED light-emitting chip 121 of each light source module 12 is independently controlled, and the emitted light of the LED light-emitting chip 121 of each light source module 12 is irradiated to the outside of the housing 11 through the focusing lens 122 to form an output light beam, and the divergence angles of the output light beams of at least two light source modules 12 are different. In this way, by controlling a single or multiple light source modules 12 to emit light, the lamp 100 can selectively emit light beams with different divergence angles, thereby helping to realize a one-lamp-multiple-angle lamp for the lamp 100, helping to meet the angle usage requirements of the lamp 100 in different scenes, and also helping to improve the flexibility of the lamp 100 adjustment, making it convenient to control the lamp 100.
