DETAILED DESCRIPTION

[0034] In combination with the attached Figure 1 , the attached Figure 2 , and the attached Figure 3A dual-light source lighting fixture includes a first light source assembly 1 with a first light source 11 and a second light source assembly 2 with a second light source 21. The first light source 11 and the second light source 21 are coaxial. The second light source assembly 2 is suspended directly above the first light source 11 and blocks the light emitted by the first light source 11 in this direction. The first light source 11 is mounted on a first lamp plate, which is installed inside the lighting fixture. The second light source 21 is mounted on a second lamp plate, which is suspended in the light-emitting direction of the first light source 11 via a connector. Due to the blocking effect of the second light source assembly 2, part of the light emitted by the first light source 11 is blocked by the second light source assembly 2, projecting a shadow area in the shape of the second light source assembly 2. Therefore, the light emitted by the first light source 11 is reflected to form a light spot with intersecting light and shadow, which serves to create atmosphere and provide overall lighting. The light emitted by the second light source 21 forms a beam of light to illuminate a specific stage area, so that the audience's gaze is focused on the area illuminated by the first light source 11. Due to the obstruction of the second light source 21, a dark area 13 exists in the light spot formed by the light emitted from the first light source 11. The formation of the dark area 13 is related to the position of the second light source 21. If the second light source 21 and the first light source 11 are not coaxial, the light spot formed by the first light source 11 will be asymmetrical from left to right due to the different areas of obstruction by the second light source 21, and the brightness of the light spot will be inconsistent from left to right, resulting in an asymmetrical dark area 13. (See attached image) Figure 8a and attached Figure 8b As shown, when the first light source 21 shifts to the left, the dark area 13 of the light spot formed by the first light source 11 also shifts to the left; the second light source assembly 2 cannot completely block the light directly emitted from the left side of the first light source 11 to the outside of the lamp, and glare will occur on the left side of the light spot formed by the first light source 11, so the brightness of the dark area 13 on the left is high; the emission angle of the reflected light on the left side of the first light source 11 is small, and the reflected light is more concentrated, so the brightness of the light spot on the left side is high and the area is small; the emission angle of the reflected light on the right side of the first light source 11 is large, and the reflected light is more diffuse, so the brightness of the light spot on the right side is low and the area is large. (See attached diagram) Figure 9a and attached Figure 9b As shown, when the second light source 21 shifts to the right, the dark area 13 of the light spot formed by the first light source 11 also shifts to the right; the second light source assembly 2 cannot completely block the light directly emitted from the right side of the first light source 11 to the outside of the lamp, and glare will occur on the right side of the light spot formed by the first light source 11, therefore the brightness of the dark area 13 on the right is high; the emission angle of the reflected light on the right side of the first light source 11 is small, the reflected light is more concentrated, the brightness of the light spot on the right is high and the area is small; the emission angle of the reflected light on the left side of the first light source 11 is large, the reflected light is more diffuse, the brightness of the light spot on the left is low and the area is large. Therefore, in this embodiment, as shown in the attached... Figure 7a and attached Figure 7bAs shown, the first light source 11 and the second light source 21 are both located in the middle of the lamp and coaxial, the second light source assembly 2 can completely block the light emitted by the first light source 11 from the lamp; when the two light sources are started together, the light emitted by the first light source 11 forms a uniform light spot, and there is also a light beam in the middle. When the second light source assembly 2 is suspended directly above the first light source 11 and is in the off state, the light emitted by the first light source 11 forms a dark area 13 due to the blocking of the second light source assembly 2. When viewed from a distance, the light effect exhibited by the first light source 11 is similar to the symbol of the computer startup key; when the second light source 21 and the first light source 11 are started together, the second light source 21 emits a concentrated light beam, which is located in the center of the left-right symmetric light spot generated by the first light source 11; the first light source 11 and the second light source 21 can be independently started or work together. The beneficial effects of this embodiment are that the first light source 11 and the second light source 21 are coaxial, so that the light spot formed by the light emitted by the first light source is uniform in brightness, and the light spot is symmetrical; the second light source assembly 2 is located directly above the first light source 11 and plays a shielding role, so that part of the light emitted by the first light source 11 is blocked, thereby creating a unique light and shadow effect, a region containing a dark area 13, forming a light spot with light and dark intersections; the second light source 21 directly projects a clear and concentrated light beam, which is in sharp contrast with the light spot of the first light source 11, enriching the overall light effect.

[0035] As a new embodiment, the accompanying drawings Figure 1 , the accompanying drawings Figure 2 and the accompanying drawings Figure 3The first light source 11 is an integrated surface light source, and the second light source 21 is a point light source. The second light source 21 is located directly above the first light source 11 and inside the lamp, and thus a light source with a small volume is required. The light emitted by the second light source 21 is a light beam, and the power requirement of the lamp bead is not high, and thus a point light source can be used. It can be understood that the light emitted by the second light source 21 can also be other effects, and the lamp bead used is different for different effects. The first light source 11 needs to use an integrated surface light source. If a common surface light source is used, the distance between the lamp beads is far, and the color mixing effect of the emitted light is not good. Although a point light source does not have the problem of color mixing, the power is not enough, which will lead to the fact that the spot brightness formed by the first light source 11 is not enough. Therefore, the first light source 11 does not use a point light source or a common surface light source. In this embodiment, the first light source 11 uses a COB light source, the power of which meets the requirement, and the color mixing effect of the emitted light is also good. It can be understood that the first light source 11 can also be other integrated surface light sources. When the power of the point light source meets the requirement, the first light source 11 can also be a point light source. The beneficial effects of this embodiment are that the point light source used by the second light source 21 emits light with uniform color mixing and a small volume; the integrated surface light source used by the first light source 11 has a large power, and the color mixing effect of the emitted light is good, and the spot brightness formed is high.

[0036] As a new embodiment, the accompanying drawings are incorporated Figure 3 , the accompanying drawings are incorporated Figure 4 and the accompanying drawings are incorporated Figure 5The first light source assembly 1 further comprises a light-reflecting bowl 12 for reflecting the light emitted by the first light source 11, and the bottom of the light-reflecting bowl 12 is provided with an opening 121 for avoiding the first light source 11. The light-reflecting bowl 12 is a circular bowl structure, and can provide uniform illumination for the stage. The light-reflecting bowl 12 is installed inside the lamp through a plurality of fixing members, and is coaxially nested with the first lamp panel installed inside the lamp at the same plane. The opening 121 at the bottom of the light-reflecting bowl 12 is circular, and its diameter is greater than the length of the first lamp panel, and the bottom of the light-reflecting bowl 12 is tightly attached to the plane. In this embodiment, the light emitted by the first light source 11 directly out of the lamp is blocked, so that the light emitted by the first light source 11 can only be reflected to the outside of the lamp through the light-reflecting bowl 12, and the light reflected by the light-reflecting bowl 12 forms a bright spot. Therefore, the vertical distance L2 from the light-emitting surface of the first light source 11 to the light-emitting end surface 124 is 125mm to 150mm, and this vertical distance L2 can ensure that all the light emitted by the first light source 11 is reflected to the outside of the lamp through the light-reflecting bowl 12. When L2 < 125mm, most of the light emitted by the first light source 11 will be directly emitted out of the lamp without being reflected by the light-reflecting bowl 12, which will cause glare. When L2 > 150mm, although it can be ensured that all the light emitted by the first light source 11 is reflected to the outside of the lamp through the light-reflecting bowl 12, the volume of the lamp will increase due to the increase in the size of the light-reflecting bowl 12, so the vertical distance L2 should be in the range of 125mm to 150mm. The beneficial effect of this embodiment is that the light emitted by the first light source 11 is collected and directed to the outside of the lamp, forming a bright spot.

[0037] As a new embodiment, the accompanying drawings Figure 6, the XY coordinate system is constructed with the axis 125 of the reflector bowl and the upper surface horizontal line 126, P0 is the upper edge point of the generatrix 127 of the reflector bowl, with coordinates (D2 / 2, 0); P1 is the control point of the Bezier curve, with coordinates (X1, Y1); P2 is the lower edge point of the generatrix 127 of the reflector bowl, with coordinates (X2, Y2); the relationship among P0, P1 and P3 satisfies B(t) = (1-t)^2 P0 + 2t(1-t) P1 + t^2 P2; when the value range 128 of P1 is 0.85*D2 / 2≤X1≤0.90*D2 / 2; 0.80*Y2≤Y1≤0.75*Y2, the light emitted by the first light source 11 will not irradiate on the bottom of the reflector bowl 12, forming a ring-shaped dark area 13, and due to the reflection of part of the light emitted by the first light source 11 on the reflector bowl 12 by the second light source assembly 2, there is also a ring-shaped light halo inside the dark area 13; when X1>0.90*D2 / 2 and Y1<0.80*Y2, the curvature of the generatrix 127 of the reflector bowl increases at this time, the light emitted by the first light source 11 will irradiate on the middle-upper position of the reflector bowl 12, and the ring-shaped dark area 13 formed also diffuses outward; when X1<0.85*D2 / 2 and Y1>0.75*Y2, the curvature of the generatrix 127 of the reflector bowl decreases at this time, the light emitted by the first light source 11 will irradiate on the middle-lower position of the reflector bowl 12, the diameter of the ring-shaped dark area 13 formed is reduced, and the range of the dark area 13 is also reduced; when the generatrix 127 of the reflector bowl is a straight line, the light emitted by the first light source 11 will irradiate on the bottom of the reflector bowl 12, so the dark area 13 will disappear. The beneficial effect of this embodiment lies in that P1 is located in the value range 128, so that a unique dark area 13 is formed at the light source, and the size of the dark area 13 is coordinated with the light halo.

[0038] As a new embodiment, in combination with the accompanying drawings Figure 3 , the accompanying drawings Figure 4 and the accompanying drawings Figure 5 , the second light source assembly 2 is located in the cavity 123 of the reflector bowl 12. The second light source assembly 2 is close to one side of the bottom of the reflector bowl 12 and is suspendedly installed in the cavity 123 through a connecting piece, and the second light source assembly 2 is coaxially nested with the reflector bowl 12. The beneficial effect of this embodiment lies in that the installation of the second light source assembly 2 in the cavity 123 can make the size of the double light source lamp smaller; the second light source assembly 2 can block part of the light reflected from the reflector bowl 12, so that there is a dark area 13 in the light spot formed by the light emitted by the first light source 11; the light reflected by the reflector bowl 12 can also serve as background light for the light beam emitted by the second light source 21, enriching the light effect of the double light source lamp.

[0039] As a new embodiment, in combination with the accompanying drawings Figure 5, the distance L1 between the second light source 21 and the first light source 11 is 25mm to 30mm. Part of the light emitted by the first light source 11 is incident on the bottom of the second light source 21, and part of the light is incident on the reflecting bowl 12; when the distance L1 between the second light source 21 and the first light source 11 is 25mm to 30mm, the light incident on the bottom of the second light source 21 is moderate, at this time, the projection of the second light source assembly 2 on the light-emitting end surface 124 of the reflecting bowl 12 is relatively coordinated with the light spot formed by the first light source 11, and the second light source assembly 2 is less affected by the heat generated by the light emitted by the first light source 11; when the distance L1 < 25mm, the second light source 21 is greatly affected by the light emitted by the first light source 11, and most of the light emitted by the first light source 11 is blocked, and the light spot formed has a lower brightness; when the distance L1 > 30mm, part of the light emitted by the first light source 11 is blocked, and most of the light is directly incident outside the lamp, causing glare; in order to make another part of the light completely reflected by the reflecting bowl, the height of the reflecting bowl 12 needs to be increased, so the volume of the lamp will increase. The beneficial effect of this embodiment is that within the range of the distance L1, it is beneficial to control the volume of the lamp, and the heat generated by the light emitted by the first light source 11 has little effect on the second light source assembly 2.

[0040] As a new embodiment, the accompanying drawings Figure 5 , L2 is the distance between the light-emitting end surface 124 of the reflecting bowl and the light-emitting surface of the first light source 11, D1 is the diameter of the light-emitting surface of the first light source 11, D2 is the diameter of the light-emitting end surface 124 of the reflecting bowl, and D3 is the diameter of the bottom of the second light source assembly 2. The relationship between D3 and L1, L2, D1, and D2 satisfies D3 ≥ L1*D2 / L2+D1. The diameter of the bottom of the second light source assembly 2 is related to the amount of light emitted by the first light source 11 blocked by the second light source assembly 2; when D3 ≥ L1*D2 / L2+D1, the second light source assembly 2 blocks the light emitted by the first light source 11 directly outside the lamp, so that the light emitted by the first light source 11 can be completely reflected by the reflecting bowl 12; or the bottom area of the second light source assembly 2 is slightly larger, which not only completely blocks the light emitted by the first light source 11 directly outside the lamp, but also blocks the light emitted by the first light source 11 directly on the reflecting bowl 12; but the bottom area of the second light source assembly 2 should not be too large, because if the bottom area of the second light source assembly 2 is too large, it will block too much light emitted by the first light source 11, so the light spot formed by the light emitted by the first light source 11 will be too dark. When D3 < L1*D2 / L2+D1, the bottom area of the second light source assembly 2 is not enough to completely block the light emitted by the first light source 11 directly outside the lamp, so that part of the light emitted by the first light source 11 is still directly incident outside the lamp without passing through the reflecting bowl 12. The beneficial effect of this embodiment is that the second light source assembly 2 completely blocks the light emitted by the first light source 11 directly outside the lamp, preventing the light emitted by the first light source 11 from directly incident outside the lamp causing glare.

[0041] As a new implementation, in combination with the accompanying drawings Figure 5 The ratio between the diameter D3 of the bottom of the second light source assembly 2 and the diameter D2 of the light-emitting end face 124 of the reflector bowl is 0.2 to 0.3. The ratio between the diameter of the light-emitting end face 124 of the reflector bowl and the diameter of the bottom of the second light source assembly 2 is related to the volume of the lamp and the light spot area formed by the light emitted by the first light source 11; therefore, in the range of 0.2 to 0.3, the light spot formed by the light emitted by the first light source 11 is adapted to the light beam emitted by the second light source 21; when the ratio of D3 / D2 is close to 0.2, the light spot area formed by the light emitted by the first light source 11 is large and the brightness is relatively low; when the ratio of D3 / D2 is close to 0.3, the light spot area formed by the light emitted by the first light source 11 is small and the brightness is relatively high; when D3 / D2<0.2, the light spot area formed by the light emitted by the first light source 11 is too large and the brightness is too low, which easily leads to the incoordination of the light-emitting areas of the two light sources, and at this time, the volume of the lamp also increases with the increase of the reflector bowl 12; when D3 / D2>0.3, the light spot area formed by the light emitted by the first light source 11 is too small and the brightness is too high, which easily leads to the incoordination of the light-emitting areas of the two light sources, and the high brightness of the light emitted by the first light source 11 easily covers the light beam emitted by the second light source 21, and at this time, the volume of the lamp also decreases with the decrease of the reflector bowl 12. The beneficial effect of this implementation is that when 0.2≤D3 / D2≤0.3, both the light beam effect of the second light source 21 and the coordination of the light-emitting areas of the two light sources can be ensured, and the light spot formed by the light emitted by the first light source 11 does not dominate.

[0042] As a new implementation, in combination with the accompanying drawings Figure 2The second light source assembly 2 further comprises a light guide element 22 for converging the light emitted by the second light source 21, and a lens 23 for changing the final light emission effect. The light guide element 22 and the lens 23 are sequentially arranged in the light emission direction of the second light source 21. The light guide element 22 is arranged above the second light source 21 and is fixed to the second light plate by a plurality of supporting legs at the lower part of the light guide element 22. The lens 23 is suspended above the light guide element 22 and is coaxially arranged with the light guide element 22 in the light emission direction of the second light source 21. In this embodiment, the light guide element 22 is a light guide column, the upper part of the light guide column is a hollow cylinder, and a rectangular light guide glass is embedded in the cylinder. The lower part of the light guide column is provided with a plurality of supporting legs for fixing the light guide column around the central axis. It can be understood that the light guide element 22 can also be a light guide plate or the like. The light guide column can also have other shapes, such as a square light guide column.

[0043] Preferably, the lens 23 for changing the light emission effect is a collimating lens. The light emission surface of the collimating lens is a semispherical surface, and the light incidence surface is a circular plane. The side surface of the collimating lens is provided with a circular ring for fixing the collimating lens, and the diameter of the circular ring is slightly larger than the diameter of the light incidence surface. The light emitted from the light guide element 22 at different angles is incident on the light incidence surface of the collimating lens, and the collimating lens converts the light with different incident angles into parallel light. The maximum angle of the light emitted from the collimating lens is not more than 4°. It can be understood that the lens 23 for changing the light emission effect can also be a prism, a lens array, or a microlens array, and the light effect formed by the lens 23 used is different. The prism can convert the light passing through it into a plurality of light 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 the same direction during propagation and does not spread to the surrounding, forming a bright light beam.

[0044] As a new embodiment, the light guide element 22 is a light guide plate, and the lens 23 is a prism. Figure 3 , the light guide element 22 is a light guide plate, and the lens 23 is a prism. Figure 4 and the light guide element 22 is a light guide plate, and the lens 23 is a prism. Figure 10The lamp body 5, the cylinder part 3 for eliminating the stray light emitted by the second light source 21, the support part 4 located in the radial direction of the reflector bowl 12 and penetrating the reflector bowl 12, one end of the support part 4 being connected with the cylinder part 3 and the other end being connected with the lamp body 5. The second light source 21 and the light guide element 22 are located inside the cylinder part 3, the inner wall of the cylinder part 3 being painted black with black paint 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 and also blocking the light emitted by the first light source 11; the cylinder part 3 is provided with a groove for installing the lens 23, the lens 23 being located above the cylinder part 3 and being installed on the cylinder part 3 through a lens pressing ring; the reflector bowl 12 is provided with an opening 122 for avoiding the support part, one end of the support part 4 being connected with the lamp body 5 through the opening 122; the support part 4 is a "7" shaped structure formed by a plurality of flat plates and is located on one side of the cylinder part 3; one end of the support part 4 is provided with a mounting hole and is installed on the reflector bowl 12 through a fixing member. In this embodiment, the cylinder part 3 is a hollow cylinder, and it can be understood that the shape of the cylinder part 3 can also be star-shaped, heart-shaped, triangular, etc. The beneficial effect of this embodiment is that the cylinder part 3 can eliminate the stray light emitted by the second light source 21, which is conducive to improving the light emitting effect of the second light source 21; the support part 4 is used to provide support for the cylinder part 3 and the second light source assembly 2 and to install the heat dissipation assembly.

[0045] As a new embodiment, in combination with the accompanying drawings Figure 2 , the accompanying drawings Figure 3 and the accompanying drawings Figure 11 , the support part 4 includes a plurality of light shielding members 41 distributed in the radial direction of the reflector bowl 12, the light shielding members 41 being used to shield part of the emitted light from the first light source 11 after being reflected by the reflector bowl 12. The light shielding members 41 are located below the support part 4; one end of the light shielding members 41 is connected with the cylinder part 3 and the other end penetrates the reflector bowl 12; the light shielding members 41 are provided with a plurality of mounting holes and are installed on the bottom surface of the support part 4 through fixing members. In this embodiment, the number of the light shielding members 41 is three, and the light source effect of the lamp seen from the outside is similar to the symbol of a Mercedes-Benz logo; it can be understood that the number of the light shielding members 41 can also be four, five or six, etc.; the more the light shielding members, the more the light emitted by the first light source is shielded; when the number of the light shielding members is four, the light source effect of the lamp seen from the outside is similar to the symbol of a cross; when the number of the light shielding members is five, the light source effect of the lamp seen from the outside is similar to the symbol of a ceiling fan; when the number of the light shielding members is six, the light source effect of the lamp seen from the outside is similar to the symbol of a plastic windmill. The beneficial effect of this embodiment is that the light shielding members 41 shield the light emitted by the first light source 11 and intentionally form the effect of the shielded light.
