Technical Field
[0001] The present invention relates to the technical field of stage lights, and more particularly to a dual-light source lamp that presents a special dark area effect at the light source. Background Art
[0002] Existing dual-light stage lights have two light sources: a main light source located at the center axis of the lamp and several side light sources distributed along its circumference. The two light sources do not block each other, thus preventing lighting effects caused by occlusion. The light from the side light sources is reflected by the reflector, so the effect created at the light source does not form a ring-shaped dark area.
[0003] Therefore, in order to form a blocked lighting effect with a ring-shaped dark area at the light source, a dual-light source lamp with a special dark area effect at the light source was developed. Summary of the Invention

DETAILED DESCRIPTION
[0030] Combined with attachment Figure 1 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 and attached Figure 10, a dual-light source lamp with a special dark area effect at the light source, comprising a first light source component 1 provided with a first light source 11 and a first lens 12, a second light source component 2 provided with a second light source 21, and a first reflective bowl 13, the first light source 11 includes a plurality of LED point light sources, the second light source 21 is a point light source, the first light source 11 and the second light source 21 are both located at the bottom of the first reflective bowl 13; the first light source component 1 and the second light source component 2 are both located in the first reflective bowl 13, and the three are installed on the same lamp board, which is conducive to the discharge of heat generated by the first light source 11 and the second light source 21; the upper surface of the first lens 12 includes a light-transmitting hole 124 located in the center for the light of the second light source 21 to transmit out, a mounting surface 125 located outside and adjacent to the light-transmitting hole 124, and a first light-emitting surface 121 located outside and adjacent to the mounting surface 125; the light-transmitting hole 124 is circular and coaxial with the second light source 21; the mounting surface 125 is a circular plane with a plurality of mounting holes; the first The light emitting surface 121 is in the shape of a ring and is inclined toward the outside of the first lens 12; the bottom of the first lens 12 is provided with an annular groove 126 with the same central axis, and multiple LED point light sources are distributed at intervals in the annular groove 126; the first lens 12 is located above the first light source 11 and the second light source 21, and is installed on the same plane as the first light source 11 and the second light source 21; the first lens 12 also includes light incident surfaces (1261, 1262, 1263) and light emitting surfaces (121, 122, 123), the light incident surfaces being the surfaces of the annular groove 126; the annular groove 126 extends from the bottom surface of the first lens 12 toward the light emitting direction of the second light source 21, and the internal surfaces of the annular groove 126 include a first light incident surface 1261, a second light incident surface 1262 and a third light incident surface 1263; the first light source assembly 1 and the second light source assembly 2 intersect at the mounting surface 125, and the second light source assembly 2 completely blocks the light emitted by the first light source 11 through the mounting surface 125. Due to the blocking of the second light source assembly 2 , the light emitted by the first light source 11 will not be mixed with the light emitted by the second light source 21 .The first lens 12 completely covers the first light source 11, so the light emitted by the first light source 11 can only reach the outside of the lamp through the first lens 12; the light emitted by the first light source 11 enters the first lens 12 through each light incident surface (1261, 1262, 1263). Since the density of the first lens 12 is different from the density of air and is greater than the density of air; according to the principle of light propagation, the light emitted by the first light source 11 will undergo a certain degree of refraction when entering the first lens 12; since the first light incident surface 1261, the second light incident surface 1262 and the third light incident surface 1263 are in different directions, the propagation directions of the light entering from different light incident surfaces (1261, 1262, 1263) are also different; in this embodiment, the appearance of the first lens 12 is a round flying saucer-shaped object. Its light-emitting surface (121, 122, 123) is a circular surface; the light emitted by the point-shaped light sources of the multiple LEDs of the first light source 11 is then emitted through the first lens 12, so that the light emitted by the point-shaped light source of each LED can be diverged to the surroundings and more uniformly, and the brightness of the light spot formed by the light emitted by the first light source 11 is consistent; when the first lens 12 is other shapes, such as a rectangle; because the rectangular lens will divide the light into multiple parts and form multiple light spots, the number of light emitted from the protruding edges of the rectangular lens is different from the number of light emitted from the light-emitting surface, and therefore a uniform and uniform light spot cannot be formed; due to the obstruction of the second light source component 2, there is a projection of the second light source component 2 in the middle of the visual effect 1 of the light-emitting surface. When the second light source 21 is working, the lighting effect formed by the second light source 21 replaces the above projection. The beneficial effect of this embodiment is that the second light source assembly 2 blocks part of the light emitted by the first light source 11, forming a lighting effect with blocking, that is, the visual effect of the light emitting surface is that there is a projection of the second light source assembly 2 in the light emitting direction in the middle; when the second light source 21 is working, the lighting effect of the blocked part will be replaced by the lighting effect formed by the second light source 21, forming a lighting effect of a combination of the first light source 11 and the second light source 21; and the first lens 12 can make the light of the first light source 11 more evenly scattered, so that the emitted light forms a light spot with uniform brightness.
[0031] As a new implementation method, combined with the Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5The light emitting surfaces (121, 122, 123) include a first light emitting surface 121 located on the upper surface of the first lens 12, a second light emitting surface 122 located on the lower surface of the first lens 12 and located outside the annular groove 126, and a third light emitting surface 123 located inside the annular groove 126. After the light emitted by the first light source 11 enters the first lens 12 through the light incident surfaces (1261, 1262, 1263), it cannot be projected from the second light emitting surface 122 and the third light emitting surface 123 to the bottom of the first reflective bowl 13 adjacent to the first lens 12. The bottom of the first lens 12 is provided with an inner cavity 127 having the same central axis as the first lens 12, and the inner cavity 127 extends from the lower surface of the first lens 12 in the light emitting direction; the third light emitting surface 123 coincides with the inner side surface of the inner cavity 127, and the third light emitting surface 123 is a curved surface, which is in the shape of a truncated cone with a small top and a large bottom; the depth of the inner cavity 127 is greater than the depth of the annular groove 126, and the area of the third light emitting surface 123 is greater than the area of the third light incident surface 1263; the second light emitting surface 122 is a curved surface, and is in the shape of a truncated cone with a large top and a small bottom, and the second light emitting surface 122 is adjacent to the first light emitting surface 121; the first light emitting surface 121 is a curved surface facing the first light emitting surface 121. The lens 12 is provided with an inclined ring on the outside; the light emitted by the first light source 11 enters the first lens 12 from the first light incident surface 1261, and then exits the first lens 12 from the first light exit surface 121, wherein a portion of the light is emitted from the outside of the lamp, and a portion of the light is reflected from the first reflective bowl 13 and exits from the outside of the first lens 12; in this embodiment, the light entering the first lens 12 cannot be emitted from the second light exit surface 122 and the third light exit surface 123, and can only be emitted from the first light exit surface 121 toward the outside of the lamp; due to the problem of the exit angle, the light emitted from the first light exit surface 121 will not be projected onto the bottom of the first reflective bowl 13, as shown in the attached figure. Figure 11 As shown, the second visual effect of the light emitting surface also includes a ring-shaped dark area formed thereby. The beneficial effect of this embodiment is that the light emitted by the first light source 11 can be concentrated so that the light emitted by the first light source 11 is projected to the outside of the lamp or the upper part of the reflective surface 131 of the first reflector 13 through the first light emitting surface 121, forming a special ring-shaped dark area at the light source and creating a unique second visual effect of the light emitting surface.
[0032] As a new implementation method, combined with the Figure 1 , Attachment Figure 9 and attached Figure 11The second light-emitting surface 122 and the third light-emitting surface 123 are both totally reflective surfaces. After light emitted from the first light source 11 enters the first lens 12, it cannot be directly emitted through the second light-emitting surface 122 or the third light-emitting surface 123. Instead, the light is reflected on the second light-emitting surface 122 or the third light-emitting surface 123 and directed toward the first light-emitting surface 121, ultimately exiting from the first light-emitting surface 121. When neither the second light-emitting surface 122 nor the third light-emitting surface 123 is a total reflection surface, when light emitted by the first light source 11 enters the first lens 12 from the second light-incident surface 121 and then exits the first lens 12 from the second light-emitting surface 122, the light refracted by the first lens 12 will be projected onto the bottom of the first reflective bowl 13. At this time, the special dark area in the middle of the second light-emitting surface visual effect is not obvious or does not exist. When light emitted by the first light source 11 enters the first lens 12 from the third light-incident surface 1263 and then exits the first lens 12 via the third light-emitting surface 123, the light refracted by the first lens 12 will interfere with the light emitted by the second light source 21, causing the light emitted by the second light source 21 to mix with the refracted light. According to the laws of optics, two conditions must be met for a total reflection surface to form: the light must enter the beam medium from a denser medium, and the angle of incidence must be greater than or equal to the critical angle. Therefore, the material density of the first lens 12 is greater than the density of air; the incident angle is related to the curvature radius of the second light emitting surface 122 and the third light emitting surface 123, so the curvature radius R2 of the second light emitting surface 122 is 10mm≤R2≤70mm, and the curvature radius R3 of the third light emitting surface 123 is 4mm≤R3≤32mm; when the curvature radius R2 of the second light emitting surface 122 is 10mm to 70mm, the light entering from the second light incident surface 1262 reaches the second light emitting surface 122, and since the light is 22 is greater than the critical angle, so the light will not be transmitted from the second light emitting surface 122; this part of the light is reflected by the second light emitting surface 122 to the first light emitting surface 121, and then emitted through the first light emitting surface 121; since the light emitted from the first light emitting surface 121 will not illuminate the bottom of the first reflective bowl 13, the light is reflected from the middle and upper part of the first reflective bowl 13 to the outside of the lamp, so there will be a special dark area in the middle of the second light emitting surface visual effect; when the curvature radius R3 of the third light emitting surface 123 is 4mm to 32 When the angle of incidence of the light entering from the third light-entering surface 1263 reaches the third light-emitting surface 123, since the incident angle of the light on the third light-emitting surface 123 is greater than the critical angle, the light will not be transmitted from the third light-emitting surface 123, thereby reducing the interference with the light emitted by the second light source 21. This part of the light is reflected by the third light-emitting surface 123 to the first light-emitting surface 121, and then emitted through the first light-emitting surface 121, making the bright part of the second visual effect of the light-emitting surface formed by the first light source 11 brighter. It is understandable that the second light-emitting surface 122 and the third light-emitting surface 123 can also be electroplated surfaces, which have the same function as the total reflection surface; or they can also be other surfaces with the same function.The beneficial effect of this embodiment is that it prevents the light emitted by the first light source 11 from being projected onto the bottom of the first reflective bowl 13 so as to form a special dark area; and concentrates the light emitted by the first light source 11 so that the contrast between the bright and dark parts of the second visual effect of the light-emitting surface is obvious.
[0033] As a new implementation method, combined with the Figure 7 , Attachment Figure 8 and attached Figure 9 , the relationship between the height H2 of the first lens 12 and the height H1 of the first reflective bowl 13 satisfies: H1 ≥ 4 * H2. The first lens 12 is coaxial with the first reflective bowl 13 and is mounted at the bottom of the first reflective bowl 13; the formation of the special dark area is related to the height of the first reflective bowl 13 and the height of the first lens 12; when H1 ≥ 4 * H2, the light emitted by the first light source 11 will illuminate the upper middle part of the first reflective bowl 13 and cannot illuminate the bottom of the first reflective bowl 13, thus forming a special dark area at the light source; in this embodiment, the height of the first lens 12 ranges from 20 mm to 35 mm, and the height of the second lens 11 ranges from 20 mm to 35 mm. The height of the light surface 122 ranges from 10 mm to 35 mm, and the height of the first lens 12 is greater than or equal to the height of the second light emitting surface 122; when the height of the first lens 12 is 20 mm to 35 mm, the height of the second light emitting surface 122 is 10 mm to 35 mm, and when the height of the first lens 12 is greater than the height of the second light emitting surface 122, the light emitted by the first light emitting surface 121 will not illuminate the bottom of the first reflective bowl 13, so a special dark area can be formed at the light source; when the first lens 12 When the height of the first lens 12 is greater than the height of the second light emitting surface 122, the first light emitting surface 121 is a circular ring inclined toward the outside of the first lens 12, and part of the light emitted from the first light emitting surface 121 is directly emitted from the lamp, and part of the light is reflected by the first reflective bowl 13. When the height of the first lens 12 is equal to the height of the second light emitting surface 122, the first light emitting surface 121 is a circular ring parallel to the horizontal plane. At this time, part of the light emitted from the first light emitting surface 121 is still reflected by the first reflective bowl 13 to the outside of the lamp; Therefore, when the height of the first lens 12 is greater than the height of the second light emitting surface 122, the first light emitting surface 121 is a circular ring inclined toward the outside of the first lens 12, and part of the light emitted from the first light emitting surface 121 is directly emitted from the lamp, and part of the light is reflected by the first reflective bowl 13 to the outside of the lamp. When the height of the first lens 12 is less than or equal to the height of the second light-emitting surface 122, it has no effect on the lighting effect formed by the first light source 11; when the height of the first lens 12 is less than 20mm, the light emitted by the first light source 11 through the first light-emitting surface 121 will illuminate the bottom of the first reflective bowl 13, thereby increasing the brightness of the area where the annular dark area originally existed, and making the annular dark area of the visual effect 2 of the light-emitting surface less obvious; when the height of the first lens 12 is greater than 35mm, the range of the special dark area also moves upward, which causes the volume of the first lens 12 and the lamp to be too large. The beneficial effect of this embodiment is that it prevents the light emitted by the first light-emitting surface 121 from irradiating the bottom of the first reflective bowl 13, which helps to make the annular dark area in the middle of the visual effect 2 of the light-emitting surface more obvious.
[0034] As a new implementation method, combined with the Figure 9 The relationship between the diameter L2 of the first lens 12 and the inner diameter L1 of the first reflector 13 is L1 ≥ 2L2. In an embodiment, the diameter L2 of the first lens 12 ranges from 100 mm to 130 mm. When the diameter L2 of the first lens 12 is less than 100 mm, the size of the light spot formed by the light emitted by the first light source 11 through the first light exit surface 121 is inconsistent with the combined light spot formed by the second light source 21. In this case, the gap between the first lens 12 and the first reflector 13 increases, and the projection point of the light emitted from the first lens 12 on the first reflector 13 moves upward, thereby increasing the range of the annular dark area formed at the light source. When the diameter L2 of the first lens 12 is greater than 130 mm, the volume of the first lens 12 increases, resulting in an excessively large lamp. In this case, the gap between the first lens 12 and the first reflector 13 decreases, and the light emitted from the first lens 12 is directly emitted to the outside of the lamp. In this case, no annular dark area is formed at the light source, or the area of the annular dark area is reduced. The beneficial effect of this embodiment is that when L2≥2L1 is satisfied, when looking from the outside to the inside of the lamp, the ratio of the first lens 12 and the first reflective bowl 13 is the most coordinated; and the lighting effect formed by the combination of the light spot formed by the light emitted by the first light source 11 through the first light-emitting surface 121 and the light beam formed by the second light source 21 is also the most coordinated.
[0035] As a new implementation method, combined with the Figure 7 and attached Figure 8The first light-emitting surface 121 is a curved surface with a beaded structure. The first light emitting surface 121 is an inclined circular curved surface with many tiny protrusions, which is inclined toward the direction of the first reflective bowl 13; the central axis of the first light emitting surface 121 coincides with the central axis of the first light source 11; since the second light emitting surface 122 and the third light emitting surface 123 are total reflection surfaces, part of the light emitted by the first light source 11 enters the first lens 12 through the first light incident surface 1261 and is emitted from the first light emitting surface 121; part of the light enters the first lens 12 through the second light incident surface 1262 or the third light incident surface 1263, and is reflected by the second light emitting surface 122 or the third light emitting surface 123 to the first light emitting surface 121, and then is emitted from the first light emitting surface 121; therefore, the light emitted by the first light source 11 is all emitted from the first light emitting surface 121, and the beaded surface structure of the first light emitting surface 121 can make the light emitted through the first light emitting surface 121 more divergent and the color mixing more uniform; and the beaded surface structure of the first light emitting surface 121 can Effectively block the shape of the blurred lamp beads; it is understandable that the first light emitting surface 121 can also be a smooth curved surface or a frosted curved surface; when the first light emitting surface 121 is a smooth curved surface, the light emitted from the first light emitting surface 121 is more concentrated, and the light scattered to the surroundings is less, and the color mixing effect of the smooth curved surface is not good, so the annular dark area in the middle of the visual effect 2 of the light emitting surface is more obvious; and the smooth curved surface cannot effectively block the shape of the lamp beads, so when the lamp is working, the shape of the lamp beads of the first light source is very obvious when looking into the inside of the lamp; when the first light emitting surface 121 is a frosted curved surface, the light emitted from the first light emitting surface 121 is the most divergent, so the color mixing effect of the frosted surface is the best; the effect of the frosted surface in blocking the shape of the lamp beads is better than the blocking effect of the curved surface with a bead structure, so when the lamp is working, the shape of the lamp beads of the first light source 11 is almost invisible when looking into the inside of the lamp, but the annular dark area in the middle of the visual effect 2 of the light emitting surface is not obvious. The beneficial effect of this embodiment is that the curved surface of the bead structure can not only make the emitted light have a better color mixing effect, but also effectively block the shape of the lamp beads; and the annular dark area in the middle of the light-emitting surface visual effect is more obvious.
[0036] As a new implementation method, combined with the Figure 9The curvature radius R1 of the reflecting surface 131 of the first reflecting bowl 13 is 30 mm to 130 mm. When the curvature radius R1 of the reflecting surface 131 is less than 30 mm, the curvature of the first reflective bowl 13 is high, and the reflection angle of the light emitted by the first light source 11 is relatively small. The reflected light on both sides of the first reflective bowl 13 will be concentrated at a point, so the brightness of the second visual effect of the light emitting surface is inconsistent. Since the light emitted by the first light source 11 will illuminate the upper middle position of the first reflective bowl 13, the annular dark area in the second visual effect of the light emitting surface also spreads outward. When the curvature radius R1 of the reflecting surface 131 is greater than 130 mm, the curvature of the first reflective bowl 13 is low, and the reflection angle of the light emitted by the first light source 11 is relatively large. The light emitted by the first light source 11 will illuminate the bottom of the first reflective bowl 13, and the reflected light on both sides of the first reflective bowl 13 is scattered in all directions. Therefore, in terms of visual effect, the area of the first visual effect of the light emitting surface is relatively larger and the brightness is consistent, but no annular dark area is formed at the light source. The beneficial effect of this embodiment is that the emission angle of the light reflected by the first light source 11 through the first reflective bowl 13 is within a suitable range, the brightness of the second visual effect of the light-emitting surface can be consistent, and the area is coordinated with the light beam effect of the second light source 21, and it is conducive to forming an annular dark area and making the annular dark area located close to the first light source 11.
[0037] As a new implementation method, combined with the Figure 6 and attached Figure 10, multiple LED point-shaped light sources are spaced apart and distributed on a circumference 211 with the first light source 11 as the center. The first light source 11 includes multiple LED point-shaped light sources, which are distributed in a circular ring shape and surround the second light source 21; the multiple LED point-shaped light sources of the first light source 11 are located in the middle position of the annular groove 126; the second light source 21 is located at the center of the circumference 211 where the first light source 11 is located, and a gap of one LED point-shaped light source is left between the multiple LED point-shaped light sources of the first light source 11 to provide sufficient space for circuit wiring; the diameter of the circumference where the first light source 11 is located is the distance from the second light source 21 to the first light source 11; in this embodiment In this method, the distance between the second light source 21 and the first light source 11 ranges from 76mm to 100mm, and the visual effect of the light-emitting surface is most coordinated with the light effect formed by the second light source 21. When the distance between the second light source 21 and the first light source 11 is less than 76mm, the light emitted by the second light source 21 may enter the light-transmitting hole of the first lens 12, interfering with the light emitted by the first light source 11. In addition, the diameter of the first lens 12 also decreases as the distance between the second light source 21 and the first light source 11 decreases, limiting the size of the first lens 12. When the distance between the second light source 21 and the first light source 11 is greater than 100mm, the diameter of the first lens 12 also increases, and the volume of the lamp also increases. The beneficial effect of this embodiment is that multiple LED point light sources are distributed at intervals, and the light emitted by the first light source 11 diverges more evenly to the surroundings, which is conducive to forming a bright and uniform light-emitting surface visual effect. The first light source 11 is located on the circumference 211 with the second light source 21 as the center, that is, the distance between the first light source 11 and the second light source 21 is within the value range, preventing the distance from being too small to affect the light source emitted by the second light source 21; or preventing the distance from being too large, causing the volume of the lamp to be too large.
[0038] As a new implementation method, combined with the Figure 1 and attached Figure 9The second light source assembly 2 further includes a light guide element 23 for converging the light emitted by the second light source 21, a cylindrical portion 24 for eliminating stray light emitted by the second light source 21, and a coaxially mounted second lens 22 for changing the light output effect. The light guide element 23, cylindrical portion 24, and second lens 22 are sequentially located in the light output direction of the second light source 21. The upper part of the light-guiding element 23 is a hollow cylinder, and a rectangular light-guiding glass is embedded inside the cylinder; the light-guiding element 23 covers the top of the second light source 21 and is installed on the lamp board through multiple supporting feet at the bottom of the light-guiding element 23, and the multiple supporting feet are distributed around the central axis; and the inner cavity 127 of the first lens 12 accommodates the light-guiding element 23, the light-guiding element 23 is coaxially installed with the first lens 12, and the top part of the light-guiding element 23 passes through the light-transmitting hole 124 of the first lens 12; the barrel 24 is provided with a groove for installing the second lens 22 and a pressure ring for fixing the second lens 22; the second lens 22 is located above the barrel 24 and is installed in the groove of the barrel 24 through the pressure ring of the second lens 22; the light emitted by the second light source 21 passes through the light-guiding element 23, and the path of the light is guided by the light-guiding element 23, propagating to the second lens 22 at different angles in the barrel 24, and then emitted to the outside of the lamp through the second lens 22. The beneficial effect of this embodiment is that it can reduce the loss of light emitted by the second light source 21; the light-guiding element 23 gathers the light and emits it in the direction of the second lens 22; the second lens 22 gathers the emitted light again, which can effectively improve the concentration and energy density of the light.
[0039] Preferably, the second lens 22 used to change the light-emitting effect is a collimating lens. The light-emitting surface of the collimating lens is hemispherical, and the light-entering surface is a circular plane; a circular ring for fixing the collimating lens is provided on the side of the collimating lens, and the diameter of the circular ring is slightly larger than the diameter of the light-entering surface; light emitted from the light-guiding element 23 at different angles is irradiated on the light-entering surface of the collimating lens, and the collimating lens converts light with different incident angles into parallel light, and the maximum angle of light emitted from the collimating lens does not exceed 4°. It can be understood that the lens used to change the light-emitting effect can also be a prism, a row of lenses, and a microlens array, etc., and the lighting effects formed by using different lenses are also different. Among them, the prism can convert the light passing through it into multiple beams. The beneficial effect of this embodiment is that the collimating lens converts light with different incident angles into parallel light, ensuring that the light maintains a consistent direction during propagation and does not spread to the surroundings to form a bright beam.
[0040] As a new implementation method, combined with the Figure 9, the height of the first reflective bowl 13 is greater than or equal to the height H3 of the second light source assembly 2. The second light source assembly 2 includes: a second light source 21, a light guide element 23, a barrel 24 and a second lens 22 coaxially distributed in sequence; the light guide element 23 is installed above the second light source 21 and embedded in the inner cavity 127 of the first lens 12; the second lens 22 is installed directly above the light guide element 23, and the second lens 22 and the light guide element 23 are coaxially installed; the distance from the second lens 22 to its focus is equal to the distance between the bottom of the second lens 22 and the light guide element 23; because when the light guide element 23 is located in front of or behind the focus of the second lens 22, the light emitted through the second lens 22 will be more concentrated or more divergent, which is not conducive to forming a beam effect. The beneficial effect of this embodiment is that it is conducive to controlling the physical total height of the second light source assembly 2 so that the volume of the lamp will not be too large; and it is convenient to install the front cover glass of the lamp, and the vertex of the second lens 22 will not directly contact the front cover glass of the lamp.
[0041] As a new implementation method, combined with the Figure 1 The barrel 24 is mounted on the mounting surface 125 of the first lens 12. The barrel 24 is a hollow cylinder with openings at both ends. The lower part of the barrel 24 is in close contact with the mounting surface 125 of the first lens 12 and is mounted on the mounting surface 125 by a fixing member. The opening at the lower part of the barrel 24 is smaller than the opening at the upper part, and the size of the opening at the lower part is consistent with the light-transmitting hole 124 of the first lens 12. The top of the light-guiding element 23 passes through the light-transmitting hole 124 of the first lens 12 and the opening at the lower part of the barrel 24 respectively. The barrel 24 covers the part of the light-guiding element 23 that protrudes from the first lens 12. The inner wall of the barrel 24 is painted black so that the stray light emitted by the second light source 21 is absorbed, preventing the stray light of the second light source 21 from affecting the light-emitting effect, while also blocking the light emitted by the first light source 11. It is understandable that the barrel 24 can also be a hollow prism or other hollow irregular columnar object with a star-shaped or heart-shaped cross-section. The beneficial effects of this embodiment are that it prevents the light emitted by the first light source 11 from entering the tube 24 through the bottom of the tube 24 and interfering with the light emitted by the second light source 21; and prevents the light emitted by the second light source 21 from diverging outside the tube 24 and weakening the brightness of the lighting effect formed by the second light source 21.
[0042] As a new implementation method, combined with the Figure 9, the size of the light-guiding element 23 is adapted to the light-transmitting hole 124. The light-transmitting hole 124 of the first lens 12 is circular, the upper part of the light-guiding element 23 is a hollow cylinder, the middle part is a circular fixing plate connected to a plurality of supporting feet, and the lower part is a plurality of supporting feet; and the size of the cylinder of the upper part of the light-guiding element 23 is smaller than the size of the light-transmitting hole 124, and the size of the circular fixing plate is smaller than the size of the light-transmitting hole; ensuring that the upper part of the light-guiding element 23 can pass through the light-transmitting hole 124 of the first lens 12, and the light-emitting hole of the light-guiding element 23 is located in the cylinder 24. The beneficial effect of this embodiment is that the upper part of the light-guiding element 23 can pass through the light-transmitting hole 124 of the first lens 12 and the lower opening of the cylinder 24, and guide the light emitted by the second light source 21 through the light-guiding element 23 to the cylinder 24 for upward emission, thereby reducing the loss of light during propagation.
