Description

Technical Field

[0001] This application relates to the field of lighting technology, specifically to a lighting device. Background Technology

[0002] Beam angle and color temperature are crucial parameters for lighting equipment. The beam angle can be altered by using lenses with different focusing angles on the light source. Small beam angles are suitable for accent lighting, while large beam angles are suitable for ambient lighting. Furthermore, different color temperatures directly affect human vision and senses, and different application scenarios require different color temperatures and beam angles. To enable lighting equipment to adapt to various lighting environments, luminaires with multiple beam angles and color temperatures are increasingly favored by users.

[0003] Currently, the beam angle of lighting equipment is usually changed by adjusting the lens focal length. However, even a small change in the lens focal length will cause a large change in the beam angle, making precise focusing difficult. In addition, this type of lighting equipment has a relatively complex structure, making it not only prone to damage but also expensive to manufacture. Summary of the Invention

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of this application.

[0047] In some processes described in the embodiments of this application, multiple operations appearing in a specific order are included. These operations may be executed out of order or in parallel. Operation numbers such as 101, 102, etc., are merely used to distinguish different operations and do not represent any execution order.

It should be noted that descriptions such as "first," "second," etc., in this document are used to distinguish different messages, devices, modules, etc., and do not represent a sequential order, nor do they limit "first" and "second" to different types. Descriptions such as "up," "down," "left," and "right" in this document are based on the directions shown in the accompanying drawings and do not represent directions in actual use.

[0048] The following will describe in detail the implementation of the embodiments of this application with reference to the accompanying drawings and examples, so that the implementation process of how the embodiments of this application use technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0049] Figure 1 This is an exploded view of a lighting device according to an embodiment of this application. Figure 2 This is a bottom view of a lighting device according to an embodiment of this application. Figures 1 to 2As shown, in one embodiment of this application, a lighting device is provided, including: a lamp body 1, a light source assembly 2, and a lens assembly 3. The light source assembly 2 is connected to the lamp body 1, and the light source assembly 2 has at least one sub-light source 21 with a color temperature. The lens assembly 3 is disposed above the light source assembly 2, and the lens assembly 3 has multiple sub-lenses with different focusing angles. The lens assembly 3 can rotate relative to the light source assembly 2 to switch the sub-lenses with different focusing angles onto one of the sub-light sources 21 with a color temperature. Specifically, the light source assembly 2 can be a sub-light source 21 with one color temperature or a sub-light source 21 with multiple color temperatures. When the light source assembly has only one sub-light source 21 with a color temperature, by rotating the lens assembly 3 to switch the sub-lenses on the sub-light source 21, a lighting device with one color temperature and multiple illumination angles can be obtained. When the light source assembly 2 has sub-light sources 21 with multiple color temperatures, different color temperature sub-light sources 21 can be selected to emit light, and then sub-lenses with different focusing angles can be selected to switch onto the sub-light source 21. By selecting and combining sub-light sources 21 with various color temperatures and sub-lenses with various focusing angles, lighting devices with multiple color temperatures and multiple focusing angles can be obtained. The above switching can be understood as changing the sub-lens with the first focusing angle on the sub-light source 21 to a sub-lens with the second focusing angle.

[0050] The number of types of illumination angles depends on the number of types of focusing angles of the sub-lenses in the lens assembly 3. When sub-lenses with different focusing angles are switched to the sub-light source 21, the light emitted by the sub-light source 21 can form a light spot with a fixed beam angle after being refracted by the sub-lenses. This can also be considered as forming illumination light with different illumination angles.

[0051] Furthermore, a heat sink, which can be a finned heat sink, is provided on one side of the lamp body 1 to cool the light source assembly 2. The other surface is recessed to form a light source cavity, in which the light source assembly 2 is disposed and tightly connected to the bottom surface of the light source cavity. The light source assembly 2 is fixed in the light source cavity by fasteners, and its back surface is tightly fitted to the bottom surface.

[0052] In the technical solution provided in this application embodiment, by rotating the lens assembly 3, sub-lenses with different focusing angles and sub-light sources 21 of one color temperature can be matched to obtain lighting devices with multiple illumination angles. In addition, by configuring sub-light sources 21 of multiple color temperatures, lighting devices with multiple color temperatures and multiple illumination angles can be realized, meeting the user's needs for lighting devices with multiple color temperatures and multiple illumination angles.

[0053] In one embodiment provided in this application, the number of sub-light sources 21 for each color temperature and the number of sub-lenses for each focusing angle can be one or more. For example, in one specific embodiment, the light source assembly 2 has three different color temperature sub-light sources 21, with one sub-light source 21 for each color temperature. The lens assembly 3 includes three different focusing angle sub-lenses, with one sub-lens for each focusing angle. As another example, in another specific embodiment, the light source assembly 2 includes three different color temperature sub-light sources 21, with multiple sub-light sources 21 for each color temperature. The lens assembly 3 includes three different focusing angle sub-lenses, with multiple sub-lenses for each focusing angle. The aforementioned sub-light sources 21 include, but are not limited to, LED chips, metal halide lamps, and incandescent lamps.

[0054] Furthermore, the light source assembly 2 is provided with multiple light source zones 7, and the sub-light sources 21 within each light source zone 7 have the same color temperature. Concentrating multiple sub-light sources 21 not only effectively improves the brightness of the light source but also facilitates the switching of sub-lenses with different focusing angles among the multiple sub-light sources 21. In the technical solution provided in this application, multiple sub-light sources 21 can correspond to one sub-lens, or one sub-light source 21 can correspond to one sub-lens.

[0055] When multiple sub-light sources 21 are centrally located in zones, in order to better match the lens assembly 3 with the light source assembly 2, in one embodiment provided in this application, the lens assembly 3 is provided with multiple lens zones 6, and the sub-lenses in each lens zone 6 have the same focusing angle. When switching between sub-lenses with different focusing angles, simply rotate the lens assembly 3 to align the lens zone 6 and the light source zone 7 to complete the switching.

[0056] See Figures 3 to 4 The light source assembly 2 includes a substrate and multiple sub-light sources 21. The substrate has multiple light source blocks 5, and each block includes multiple light source partitions 7. Each light source partition 7 has multiple sub-light sources 21. The color temperature of the sub-light sources 21 in each light source partition 7 is the same, and the number of sub-light sources 21 in different light source partitions 7 can be the same or different.

[0057] In one specific embodiment, such as Figure 3 As shown, the aluminum substrate of the light source assembly 2 has six fan-shaped light source blocks 5. Each fan-shaped light source block 5 contains the same number of light source sub-light sources 7, and the color temperature of the sub-light sources 21 within each light source sub-light source 7 is the same. Light source sub-light sources 7 with larger areas contain more sub-light sources 21, and adjacent light source sub-light sources 21 have different color temperatures. For example, the color temperature of the sub-light source 21 in the first light source sub-light source 71 is 4000K, the color temperature of the sub-light source 21 in the second light source sub-light source 72 is 3000K, and the color temperature of the sub-light source 21 in the third light source sub-light source 73 is 5000K.

[0058] Furthermore, such as Figure 4 As shown, lens assembly 3 also has six fan-shaped lens blocks 4. When lens assembly 3 and light source assembly 2 are used together, the six fan-shaped lens blocks 4 of lens assembly 3 correspond to the six fan-shaped light source blocks 5 of light source assembly 2. Each fan-shaped lens block 4 of lens assembly 3 has the same number of lens sections 6, and each lens section 6 has multiple sub-lenses. The focusing angle of the sub-lenses in each lens section 6 is the same, and the number of sub-lenses in different lens sections 6 can be the same or different. A larger lens section 6 has more lenses, and the focusing angles of the sub-lenses in adjacent lens sections 6 are different. For example, see... Figure 4 The focusing angle of the sub-lens in the first lens section 61 is 120 degrees, the focusing angle of the sub-lens in the second lens section 62 is 60 degrees, and the focusing angle of the sub-lens in the third lens section 63 is 90 degrees.

[0059] Furthermore, after the lens assembly 3 rotates and switches, the first lens partition 61 on the first light source partition 71 of the first color temperature becomes the fifth lens partition 65, and the focusing angles of the first lens partition 61 and the fifth lens partition 65 are different. Specifically, the rotation angle of the lens assembly 3 is determined by the number of blocks in the light source assembly 2 or the lens assembly 3. For example... Figure 3 and Figure 4 In the design, both the circular light source assembly 2 and lens assembly 3 are divided into six blocks, each occupying 60 degrees. Therefore, when switching the lens assembly 3, simply rotate it 60 degrees clockwise or counterclockwise to switch the first lens partition 61 on the first light source partition 71 of the first color temperature to the fifth lens partition 65. When further switching is required, simply rotate the lens assembly 3 to achieve the desired switch.

[0060] The technical solution of this application will be described in detail below through specific embodiments.

[0061] Taking a sub-light source 21 with only one color temperature on the light source assembly 2 as an example, see... Figure 5 and Figure 6 The circular light source assembly 2 is divided into six light source blocks 5, and each light source block 5 has multiple light source sections 7. When the light source assembly 2 has only one color temperature sub-light source 21, some light source sections 7 have sub-light sources 21, while others do not. For example, the first light source section 71 and the fourth light source section 74 in the first light source block 51 both have sub-light sources 21 with a color temperature of 4000K, while the second light source section 72 does not have a sub-light source 21. Correspondingly, one lens block 4 of the lens assembly 3 has multiple lens sections 6. The sub-lenses in the first lens section 61 and the fourth lens section 64 of the first lens block 41 have the same focusing angle, for example, 120 degrees.

[0062] See Figure 7 When the lens assembly 3 is rotated 60 degrees counterclockwise, the second lens block 42 of the lens assembly 3 corresponds to the first light source block 51. At this time, the fifth lens section 65 and the eighth lens section 68 of the second lens block 42 of the lens assembly 3 correspond to the first light source section 71 and the fourth light source section 74 of the first light source block 51, respectively. Since the focusing angle of the sub-lenses in the fifth lens section 65 and the eighth lens section 68 of the second lens block 42 is the same, and is 90 degrees, the focusing angle of the sub-lenses set on the sub-light source 21 can be directionally changed by rotating the lens assembly 3.

[0063] It should be noted that, see Figures 5 to 8 The light source block 5 with a sub-light source 21 having a color temperature of 4000K is not limited to the first light source block 51 and the second light source block 52. Some light source partitions 7 in other light source blocks 5 on the light source assembly 2 also have sub-light sources 21 with a color temperature of 4000K, and the lens partitions 6 corresponding to these light source partitions 7 also have sub-lenses with the same focusing angle. When switching, the lens partitions 6 (sub-lenses with a focusing angle of 120 degrees) on all sub-light source 21 partitions with a color temperature of 4000K will be switched to another lens partition 6 (sub-lenses with a focusing angle of 90 degrees).

[0064] See Figure 8 When rotated 60 degrees clockwise, the third lens block 43 of the lens assembly 3 corresponds to the first light source block 51. At this time, the ninth lens section 69 and the twelfth lens section 612 of the third lens block 43 of the lens assembly 3 correspond to the first light source section 71 and the fourth light source section 74 of the first light source block 51, respectively. The focusing angle of the sub-lenses in the ninth lens section 69 and the twelfth lens section 612 is 60 degrees. Therefore, after rotating 60 degrees clockwise, the sub-lenses with a focusing angle of 120 degrees on the first light source section 71 and the fourth light source section 74 will switch to sub-lenses with a focusing angle of 60 degrees.

[0065] Furthermore, multiple light source zones 7 with different color temperatures form a light source block 5, and the different light source zones 7 within different light source blocks 5 are arranged in different positions. For example, see... Figure 3In the first light source block 51, the first light source partition 71 is a sub-light source 21 with a color temperature of 4000K; in the second light source block 52, the fifth light source partition 75 is a sub-light source 21 with a color temperature of 5000K; and in the third light source block 53, the ninth light source partition 79 is a sub-light source 21 with a color temperature of 3000K. By distributing the light source partitions 7 containing sub-light sources 21 of different color temperatures at different positions in the light source block 5, the sub-light sources 21 of different color temperatures can be more evenly distributed on the substrate of the light source assembly 2, and the light emitted by the entire lighting device will be softer and more uniform.

[0066] Furthermore, multiple lens sections 6 with different focusing angles form a lens block 4, and the different lens sections 6 within different lens blocks 4 are arranged in different positions. For example, see... Figure 4 The first lens section 61 in the first lens block 41 is a sub-lens with a focusing angle of 120 degrees, the fifth lens section 65 in the second lens block 42 is a sub-lens with a focusing angle of 90 degrees, and the ninth lens section 69 in the third lens block 43 is a sub-lens with a focusing angle of 60 degrees.

[0067] It should be noted that the light source assembly 2 and lens assembly 3 include, but are not limited to, circular, directional, polygonal, etc. For example, in one embodiment provided in this application, the light source assembly 2 and lens assembly 3 are regular hexagons, and each equilateral triangular region of the regular hexagon is a block. The number of blocks provided on the light source assembly 2 and lens assembly 3 is not specifically limited; there can be one or more.

[0068] See Figure 1 , Figure 2 and Figure 15 To enable the lighting device to switch between multiple color temperatures, the device also includes a switch with multiple positions. Specifically, the light source assembly 2 includes sub-light sources 21 with multiple color temperatures, which are connected in series or parallel. Different positions of the switch correspond to sub-light sources 21 with different color temperatures. When the switch is turned on, the sub-light sources 21 with the same color temperature at one of the positions emit light simultaneously. In one specific embodiment, the switch has five positions: R, 3000K, 4000K, 5000K, and L. When the switch is indicated at different positions, the sub-light sources 21 with different color temperatures will emit light. The R position can be considered as the switch being turned to the right to its limit; continuing to turn the switch will cause the lens assembly 3 to rotate to the right as well. The L position can be considered as the switch being turned to the left to its limit; continuing to turn the switch will cause the lens assembly 3 to rotate to the left as well.

[0069] In the technical solution provided in this application, sub-light sources 21 with different color temperatures are selectively lit by a multi-position switch, and then sub-lenses with different focusing angles are selectively placed on the light-emitting sub-light sources 21 by rotating the lens assembly 3, thereby realizing a lighting device with multiple color temperatures and multiple illumination angles that can be combined and selected.

[0070] The following describes in detail a lighting device with multiple color temperatures and multiple illumination angles that can be combined and selected through specific embodiments.

[0071] In one specific embodiment, see Figure 9 In this state, the lens assembly 3 has the following configurations: lens section 6 with a focusing angle of 120 degrees corresponds to the light source section 7 with a color temperature of 4000K; lens section 6 with a focusing angle of 60 degrees corresponds to the light source section 7 with a color temperature of 3000K; and lens section 6 with a focusing angle of 90 degrees corresponds to the light source section 7 with a color temperature of 5000K. Therefore, when the switch is adjusted to the 4000K color temperature setting, the lighting device can emit light with a color temperature of 4000K and a light angle of 120 degrees. Furthermore, when the switch is adjusted to the 3000K color temperature setting, the lighting device can emit light with a color temperature of 3000K and a light angle of 60 degrees. Still further, when the switch is adjusted to the 5000K color temperature setting, the lighting device can emit light with a color temperature of 5000K and a light angle of 90 degrees.

[0072] exist Figure 9 Based on this, after rotating lens assembly 3 counterclockwise by 60 degrees, see [link / reference]. Figure 10 In this state, the lens assembly 3 has the following configurations: lens section 6 with a focusing angle of 90 degrees corresponds to the light source section 7 with a color temperature of 4000K; lens section 6 with a focusing angle of 120 degrees corresponds to the light source section 7 with a color temperature of 3000K; and lens section 6 with a focusing angle of 60 degrees corresponds to the light source section 7 with a color temperature of 5000K. Therefore, when the switch is adjusted to the 4000K color temperature setting, the lighting device emits light with a color temperature of 4000K and a light angle of 90 degrees. Furthermore, when the switch is adjusted to the 3000K color temperature setting, the lighting device emits light with a color temperature of 3000K and a light angle of 120 degrees. Still further, when the switch is adjusted to the 5000K color temperature setting, the lighting device emits light with a color temperature of 5000K and a light angle of 60 degrees.

[0073] exist Figure 9 After rotating lens assembly 3 60 degrees clockwise, see [link / reference] Figure 11In this state, the lens assembly 3 has the following configurations: lens section 6 with a focusing angle of 60 degrees corresponds to the light source section 7 with a color temperature of 4000K; lens section 6 with a focusing angle of 90 degrees corresponds to the light source section 7 with a color temperature of 3000K; and lens section 6 with a focusing angle of 120 degrees corresponds to the light source section 7 with a color temperature of 5000K. Therefore, when the switch is adjusted to the 4000K color temperature setting, the lighting device can emit light with a color temperature of 4000K and a light angle of 60 degrees. Furthermore, when the switch is adjusted to the 3000K color temperature setting, the lighting device can emit light with a color temperature of 3000K and a light angle of 90 degrees. Still further, when the switch is adjusted to the 5000K color temperature setting, the lighting device can emit light with a color temperature of 5000K and a light angle of 120 degrees.

[0074] In one embodiment provided in this application, see Figure 1 , Figure 2 and Figure 15 To facilitate user adjustment of different color temperature levels, a rotary switch 8 is provided, located on the axis of the lamp body 1, with the knob protruding above the lens assembly 3. The lens assembly 3 and the light source assembly 2 have mounting holes. The rotary switch 8 passes through the lens assembly 3 and the light source assembly 2 and is connected to the lamp body 1 via a fastener 15, with a washer 16 between the fastener 15 and the lens assembly 3. When the lighting equipment is suspended and installed, users can easily adjust the color temperature by grasping and rotating the knob protruding above the lens assembly 3. Furthermore, the rotary switch 8, located on the axis of the lamp body 1, coincides with the center of gravity of the lamp body 1, making operation more stable.

[0075] In one embodiment provided in this application, the rotary switch 8, in addition to switching different switch positions, can also drive the lens assembly 3 to rotate. Specifically, see... Figure 1 , Figure 2 , Figure 12 , Figure 15 and Figure 16The rotary switch 8 includes a rotatable inner core and a housing, with three protrusions 17 on the housing. The lens assembly 3 has a torsion groove 18, into which the three protrusions 17 are inserted when the rotary switch 8 and the lens assembly 3 are installed. The included angle between two torsion grooves 18 is 100 degrees. When the rotary switch 8 is adjusted to the 3000K, 4000K, and 5000K color temperature settings, the rotatable inner core rotates relative to the housing to achieve the gear shift. When the rotary switch 8 is further rotated to the R position, the inner core and housing rotate together, and the rotational force is transmitted to the lens assembly 3, driving the lens assembly 3 to rotate to the right. Similarly, when the rotary switch 8 is further rotated to the L position, the inner core and housing rotate together, and the rotational force is transmitted to the lens assembly 3, driving the lens assembly 3 to rotate to the left.

[0076] See Figure 1 , Figure 13 and Figure 14 In one embodiment provided in this application, the lighting device further includes a pressure ring 9 and an adjusting member 10. The pressure ring 9 is connected to the lamp body 1 and forms a gap groove, in which the lens assembly 3 is disposed. The pressure ring 9 can limit the position of the lens assembly 3, and the lens assembly 3 can slide in the gap groove. The adjusting member 10 is connected to the pressure ring 9, and one end of the adjusting member 10 abuts against the lens assembly 3, used to adjust the distance between the lens assembly 3 and the light source assembly 2. Specifically, the adjusting member 10 is movably connected to the pressure ring 9, and the end of the adjusting member 10 that abuts against the lens assembly 3 can drive the lens assembly 3 away from or closer to the light source assembly 2. In a specific embodiment, see [link to specific embodiment]. Figure 13 The adjusting component 10 is a non-removable hexagonal screw 91, which passes through the mounting lug 93 of the retaining ring 9. A retaining ring 92 is fitted onto the narrow neck of the non-removable hexagonal screw 91 to prevent it from disengaging from the retaining ring 9. When the screw is rotated, the end of the screw actuates the retaining ring 9, thereby causing the lens assembly 3 to move closer to or further away from the light source assembly 2.

[0077] In addition to adjusting the distance between the lens assembly 3 and the light source assembly 2, the adjusting member 10 can also limit the position of the lens assembly 3. For example, when the user needs to rotate the lens assembly 3 to switch the focusing angle, the adjusting member 10 must first be rotated to move the lens assembly 3 away from the light source assembly 2, after which the lens assembly 3 becomes rotatable. After the user completes the switch, the adjusting member 10 is rotated in the opposite direction to move the lens assembly 3 closer to the light source assembly 2, making the two tightly connected, thereby limiting the position of the lens assembly 3 and preventing it from rotating arbitrarily. By using the adjusting member 10 to move the lens assembly 3 away from the light source assembly 2 during angle switching, not only is it convenient for the lens assembly 3 to rotate, but the sub-light source 21 on the light source assembly 2 is also effectively protected.

[0078] Further, see Figure 14 To improve the limiting effect of the pressure ring 9 on the lens assembly 3, a limiting member 94 is also provided on the pressure ring 9. One end of the limiting member 94 passes through the pressure ring 9 and abuts against the edge of the lens assembly 3. By adjusting the tightness of the limiting member 94 and the lens assembly 3, the limiting and loosening of the lens assembly 3 can be achieved. In addition, the limiting member 94 cooperates with the protrusion 95 of the lens assembly 3, thereby effectively preventing the lens assembly 3 from detaching from the pressure ring 9. In a specific embodiment, the limiting member 94 is a screw. One end of the screw passes through the pressure ring 9 and is connected to the protrusion 95 of the lens assembly 3, thereby ensuring that the lens assembly 3 can only rotate freely within the limited space left by the screw and cannot leave the pressure ring 9.

[0079] To prevent damage to the sub-light source 21 during the rotation of the lens assembly 3, see [reference needed]. Figure 12 and Figure 14 The lens assembly 3 has an annular groove 11 on the side facing the light source assembly 2. When the lens assembly 3 is positioned above the light source assembly 2, the sub-light source 21 is located in the annular groove 11. When the lens assembly 3 rotates, the sub-light source 21 located in the annular groove can effectively avoid colliding with the lens assembly 3.

[0080] Furthermore, as mentioned above, in order to enable the light source assembly 2 to emit more uniform and softer light, multiple sub-light sources 21 are arranged in a concentric ring on the substrate of the light source assembly 2. Corresponding to the arrangement of the photon light sources 21, the position of the annular groove 11 corresponds to the position of the sub-light sources 21. Multiple annular grooves are arranged in a concentric circle on one side of the light source assembly 2, and the positions of different light source sections 7 correspond to the positions of different annular grooves 11.

[0081] See Figure 1 and Figure 14 In one embodiment provided in this application, a sealing element 12 is provided between the light source assembly 2 and the lens assembly 3, and the sealing element 12 is connected to both the light source assembly 2 and the lens assembly 3. The lens assembly is provided with a receiving groove 19, and the sealing element 12 is disposed within the receiving groove 19. After the distance between the lens assembly 3 and the light source assembly 2 is shortened by the adjusting element 10, the sealing element 12 seals the space between the lens assembly 3 and the light source assembly 2, thereby effectively improving the waterproof effect of the lighting device.

[0082] Furthermore, to facilitate users in selecting different color temperatures and lighting angle combinations, indicator markings are provided on the lamp body 1. Different indicator markings correspond to different combination modes, and these markings can be patterns, text, or symbols. See also Figure 2 , Figures 6 to 11Multiple text markings are provided on the pressure ring 9, and an indicator is provided on the lens assembly 3. When the indicator points to a text marking, it indicates that the lens assembly 3 is in the current position. By selecting different color temperatures, three different color temperatures and three different illumination angles can be obtained. For example... Figure 9 In the image, the arrow indicator on lens assembly 3 points to the text markings 4K-120D, 3K-60D, and 5K-90D. This indicates that when the color temperature is selected as 4000K, the illumination angle is 120 degrees; when the color temperature is selected as 3000K, the illumination angle is 60 degrees; and when the color temperature is selected as 5000K, the illumination angle is 90 degrees.

[0083] Furthermore, to facilitate user selection of different color temperatures, text markings are also provided on the lens assembly 3, and an indicator arrow is provided on the knob switch 8. When the arrow points to a certain color temperature text marking, it indicates that the color temperature represented by the text marking is the current color temperature of the light source assembly 2. For example, 3K indicates a color temperature of 3000K, etc.

[0084] In summary, the technical solution provided in this application embodiment allows for the matching of sub-lenses with different focusing angles and sub-light sources of one color temperature by rotating the lens assembly, thereby obtaining lighting devices with multiple illumination angles. By configuring sub-light sources of multiple color temperatures, lighting devices with multiple color temperatures and multiple illumination angles can be achieved, meeting users' needs for lighting devices with multiple color temperatures and multiple illumination angles. Furthermore, the lens assembly has an annular groove, which effectively prevents collisions between the lens assembly and the light source assembly when the lens assembly rotates, ensuring the safety of the light source assembly.
