Specific implementation manner

[0047] Embodiment 1: At least one group of spiral light-emitting areas evenly distributed around the center of the first light source substrate:

[0048] Combined with the attached Figure 1 and the attached Figure 2a, A lamp with a windmill rotation lighting effect, comprising an annular first light source substrate 1, multiple first light sources 11 disposed on the first light source substrate 1, and a light output lens 3. It further includes a light blocking member 4 adapted to the shape of the first light source substrate 1. The light blocking member 4 includes an outer frame 41 for enclosing the multiple first light sources 11 and multiple light blocking sheets 42 for dividing the multiple first light sources 11 into multiple independent lighting areas and preventing light leakage between them. The multiple independent lighting areas include at least one set of spiral lighting areas 12 evenly distributed around the center of the first light source substrate 1. The first light source substrate 1, the light blocking member 4, and the light output lens 3 are coaxially installed in sequence; the light blocking member 4 is composed of multiple arc-shaped light blocking sheets 42; the light blocking sheets 42 are spirally distributed around the center of the first light source substrate 1, dividing the multiple first light sources 11 into multiple spiral lighting areas 12. Multiple fixing holes for installing the light blocking member 4 are provided at the bottom of the inner wall of the outer frame 41. The beneficial effect of this embodiment is that the light blocking sheets 42 divide the first light sources 11 into multiple independent spiral lighting areas 12, enabling the multiple independent spiral lighting areas 12 to form an effect similar to the rotation of a windmill under a certain control method; and due to the blocking of the light blocking sheets 42, a distinct dividing line can be formed between the lighting effects formed by every two adjacent spiral lighting areas 12, preventing the lighting effects formed between every two adjacent independent lighting areas from mixing light with each other.

[0049] As a new embodiment, in combination with the attached Figure 2b and the attached Figure 2c, at least one set of spiral light-emitting regions evenly distributed around the center of the first light source substrate 1, including a plurality of identical spiral light-emitting regions 12. The spiral light-emitting region 12 includes several spiral light-emitting units 121, and the spiral light-emitting unit 121 includes multiple first light sources 11. A plurality of identical arc-shaped light-blocking pieces 42 divide the first light sources 11 into a plurality of spiral light-emitting regions 12 with equal areas. Therefore, the number of spiral light-emitting units 121 in each spiral light-emitting region 12 is equal, and the total number of first light sources 11 in each spiral light-emitting region 12 is also equal; the shape of the spiral light-emitting unit 121 conforms to the radian of the light-blocking piece 42, and the light-blocking piece 42 is located within the same light-emitting region and relatively close to the spiral light-emitting region 12; therefore, the first light sources 11 within the same spiral light-emitting unit 121 are also arranged according to the radian of the light-blocking piece 42. Of course, the arrangement of the first light sources 11 also needs to achieve a uniform light-emitting effect. In this embodiment, a set of spiral light-emitting regions includes six independent spiral light-emitting regions 12, and one spiral light-emitting region 12 includes two spiral light-emitting units 121; three first light sources 11 are provided in one of the spiral light-emitting units 121, and four first light sources 11 are provided in the other spiral light-emitting unit 121; the number and area of the spiral light-emitting regions 12 are related to the volume of the lamp. When the volume of the lamp increases, the number of spiral light-emitting regions 12 increases; or the number of spiral light-emitting regions 12 remains unchanged but the area increases. At this time, the number of first light sources 11 in each spiral light-emitting region 12 will also increase accordingly; when the volume of the lamp decreases, the number of spiral light-emitting regions 12 decreases; or the area decreases, and at this time, the number of first light sources 11 in each spiral light-emitting region 12 decreases accordingly; it can be understood that the number of spiral light-emitting regions 12 can also be seven, eight, nine, etc., the spiral light-emitting units 121 located in the spiral light-emitting region 12 can also be three, four, five, etc., and the number of first light sources 11 can also be five, six, seven, etc.; the lighting effect formed by a set of spiral light-emitting regions is a lighting effect similar to that of a rotating windmill, which has a great relationship with the spiral light-emitting regions 12 arranged in a spiral manner. The beneficial effect of this embodiment is that a set of spiral light-emitting regions can form a spiral windmill effect contour, and the multiple first light sources 11 of a set of spiral light-emitting regions can form a lighting effect of a windmill rotating effect when working, and its lighting color can also be various.

[0050] Embodiment 2: At least two sets of light-emitting regions arranged in sequence and evenly spaced around the center of the first light source substrate:

[0051] The difference between Embodiment 2 and Embodiment 1 lies in the structure of the light-blocking member 4 and the arrangement of the multiple first light sources 11 provided on the first light source substrate 1. Combining with the attached Figure 3a and the attached Figure 3e 、the attached Figure 4a and the attached Figure 4e 、the attachedFigure 5a and the attached Figure 5e and the attached Figure 6a and the attached Figure 6e , the multiple independent light-emitting regions include at least two groups of light-emitting regions arranged in sequence and evenly spaced around the center of the first light source substrate 1. At this time, the arrangement of the light-blocking sheet 42 is slightly different from that of the light-blocking sheet 42 of the spiral light-emitting region 12. The light-blocking sheet 42 is divided into a first light-blocking sheet 43 and a second light-blocking sheet 44, and the first light-blocking sheet 43 and the second light-blocking sheet 44 are arranged in an array around the center of the first light source substrate 1; there are the following four implementation manners respectively:

[0052] Implementation manner one: As shown in the attached Figure 3a and the attached Figure 3e , the shapes of the first light-blocking sheet 43 and the second light-blocking sheet 44 are both arc-shaped, and the two are connected end to end to form an ellipse and perform a circular array around the center of the first light source substrate 1; the first light-blocking sheet 43 and the second light-blocking sheet 44 divide the first light source 11 into a group of elliptical light-emitting regions and a group of ax-shaped light-emitting regions; the two groups of light-emitting regions are evenly distributed around the center of the first light source substrate 1 in an interlaced manner, and the combination of the two groups of light-emitting regions is a ring.

[0053] Implementation manner two: As shown in the attached Figure 4a and the attached Figure 4e , the first light-blocking sheet 43 and the second light-blocking sheet 44 are respectively two rectangular flat plates with different lengths. The first light-blocking sheet 43, the second light-blocking sheet 44 and the outer frame 41 are connected to form a sector and are evenly arranged in an array around the center of the first light source substrate 1; the first light source 11 is divided into a group of sector-shaped light-emitting regions and a group of trapezoidal light-emitting regions, and the two groups of light-emitting regions are evenly distributed around the center of the first light source substrate 1 in an interlaced manner, and the combination of the two groups of light-emitting regions is a ring.

[0054] Implementation manner three: As shown in the attached Figure 5a and the attached Figure 5e , the first light-blocking sheet 43 and the second light-blocking sheet 44 are both composed of two rectangular flat plates spliced together. The two light-blocking sheets enclose a diamond-shaped light-emitting region and perform a circular ring array around the center of the first light source substrate 1; the first light-blocking sheet 43 and the second light-blocking sheet 44 divide the first light source 11 into a group of diamond-shaped light-emitting regions and a group of funnel-shaped light-emitting regions; the two groups of light-emitting regions are evenly distributed around the center of the first light source substrate 1 in an interlaced manner, and the combination of the two groups of light-emitting regions is a ring.

[0055] Implementation manner four: As shown in the attached Figure 6a and the attached Figure 6eAs shown, the first light blocking sheet 43 is formed by splicing two rectangular flat plates, and the second light blocking sheet 44 is a rectangular flat plate; one end of the first light blocking sheet 43 is connected to the second light blocking sheet 44, and the other end is connected to the outer frame, and the shape of the enclosed light emitting area is trapezoidal; the first light blocking sheet 43 and the second light blocking sheet 44 are arranged in a circular ring array around the center of the first light source substrate 1, dividing the first light source 11 into a group of trapezoidal light emitting areas and a group of boot-shaped light emitting areas; the two groups of light emitting areas are evenly distributed around the center of the first light source substrate 1 and interpenetrate each other, and the two groups of light emitting areas are combined into a circular ring shape.

[0056] The beneficial effects of the above four embodiments are that the first light blocking sheet 43 and the second light blocking sheet 44 divide the first light source 11 into multiple independent light emitting areas (131, 141), so that the multiple independent light emitting areas (131, 141) can form the effect of a windmill rotating under a certain control method; and a distinct dividing line can be formed between the lighting effects formed by every two adjacent independent light emitting areas (131, 141), and the lighting effects formed between every two adjacent independent light emitting areas (131, 141) will not be mixed.

[0057] In terms of the shape of the light emitting area and the arrangement of the first light source in the light emitting area:

[0058] Combined with attached Figures 3b to 3e , attached Figures 4b to 4e , attached Figures 5b to 5e and attached Figures 6b to 6e, at least two groups of light-emitting regions evenly spaced around the center of the first light source substrate 1 in sequence, including the first light-emitting region group 13 and the second light-emitting region group 14; among them, the first light-emitting region group 13 includes a plurality of identical and spaced-apart first light-emitting regions 131, the second light-emitting region group 14 includes a plurality of identical and spaced-apart second light-emitting regions 141, and the shapes of the first light-emitting regions 131 and the second light-emitting regions 141 are different. Both the first light-emitting regions 131 and the second light-emitting regions 141 include multiple first light sources 11. The first light-emitting regions 131 and the second light-emitting regions 141 are interspersed around the center of the first light source substrate 1. The first light sources 11 located in the first light-emitting regions 131 and the first light sources 11 located in the second light-emitting regions 141 are also interspersed; and the arrangement of the first light sources 11 should also ensure that the brightness of the lighting effects formed by the first light-emitting regions 131 and the second light-emitting regions 141 is consistent, and there are no dark corners in the formed lighting effects; the number of the first light sources 11 located in the first light-emitting regions 131 is not equal to the number of the first light sources 11 located in the second light-emitting regions 141. Since the area of each first light-emitting region 131 is equal, the number of the first light sources 11 arranged in the first light-emitting regions 131 is also equal; the area of each second light-emitting region 141 is also equal, and the number of the first light sources 11 arranged inside it is also equal; when the multiple first light sources 11 of the first light-emitting region group 13 and the second light-emitting region group 14 work together, one group of light-emitting regions serves as the background light effect, and the other group of light-emitting regions rotates different colors of lights; a lighting effect of a rotating windmill is formed. There are the following implementation manners for the shape of the light-emitting regions and the arrangement of the first light sources 11:

[0059] Embodiment 1: Referring to Figures 3b to 3e and Figure 8a , when the shape of the first light-emitting region 131 is oval, the first light-emitting region group 13 is an annular array of multiple first light-emitting regions 131. At this time, the shape of the second light-emitting region 14 is ax-shaped; among them, the number of the first light sources 11 in the first light-emitting region 131 is three, and the number of the first light sources 11 in the second light-emitting region 141 is two; since the second light-emitting region 141 has more corners, the first light sources 11 distributed in the second light-emitting region 141 are relatively scattered, so that there are no dark corners in the lighting effect formed by the second light-emitting region 141; it can be understood that the number of the first light sources 11 in the first light-emitting region 131 or the second light-emitting region 141 can also be four, five, six; at this time, the formed lighting effect is a flower-shaped rotating windmill lighting effect.

[0060] Embodiment 2: Referring to Figures 4b to 4e and Figure 8bWhen the shape of the light-emitting area 131 is a trapezoid, the light-emitting area group 13 is a circular array of multiple light-emitting areas 131, and the light-emitting area 2 141 is a fan-shaped; the area of the light-emitting area 2 141 is larger than the area of the light-emitting area 131. In order to ensure that the brightness of the lighting effects formed by the two groups of light-emitting areas is consistent, the number of first light sources 11 in the light-emitting area 2 141 is greater than the number of first light sources 11 in the light-emitting area 131; wherein the number of first light sources 11 in the light-emitting area 131 is two, and the number of first light sources 11 in the light-emitting area 141 is five; it can be understood that the number of first light sources 11 in the light-emitting area 131 or the light-emitting area 2 141 can also be six, seven, or eight; the lighting effect formed at this time is a five-pointed star-shaped windmill rotating lighting effect.

[0061] Implementation method three: Combined with the attached Figures 5b to 5e , when the shape of the light-emitting area 131 is a diamond shape, the light-emitting area group 13 is a circular array of multiple light-emitting areas 131, and the light-emitting area 2 141 is in the shape of a funnel; the area of the light-emitting area 2 141 is larger than the area of the light-emitting area 131, so the number of first light sources 11 located in the light-emitting area 2 141 is greater than the number of first light sources in the light-emitting area 131; wherein the number of first light sources 11 in the light-emitting area 131 is two, and the number of first light sources 11 in the light-emitting area 2 141 is three; in order to make the light brightness formed by the light-emitting area 2 141 consistent, the first light sources 11 in the light-emitting area 2 141 are arranged in a triangle; it can be understood that the number of first light sources 11 in the light-emitting area 131 or the light-emitting area 2 141 can also be four, five, or six; the light effect formed at this time is as shown in the attached figure Figure 8c shown.

[0062] Implementation method 4: Combined with attachment Figures 6b to 6e and attached Figure 8d , when the shape of the light-emitting area 131 is a trapezoid, the light-emitting area group 13 is a circular array of multiple light-emitting areas 131, and the light-emitting area 2 141 is in the shape of a boot; the area of the light-emitting area 131 is larger than the area of the light-emitting area 2 141, so the number of first light sources 11 arranged in the light-emitting area 131 is greater than the number of first light sources 11 arranged in the light-emitting area 2 141; wherein the number of first light sources 11 in the light-emitting area 131 is five, and the number of first light sources 11 in the light-emitting area 2 141 is two; the shape of the light-emitting area 2 141 is relatively irregular, in order to prevent the lighting effect formed by the light-emitting area 2 141 from having dark corners, the first light sources 11 in the light-emitting area 2 141 should be arranged according to the shape of the first light-cutting piece 43; it can be understood that the number of first light sources 11 in the light-emitting area 131 or the light-emitting area 2 141 can also be six, seven, or eight; the lighting effect formed at this time is a "卐"-shaped windmill rotating lighting effect.

[0063] The beneficial effects of the above four embodiments are that the shapes of the first light-emitting area group 13 and the second light-emitting area group 14 are diverse, which is conducive to forming various windmill rotation lighting effects with different effects.

[0064] Based on the above-mentioned first embodiment and second embodiment, there are also the following implementation manners that are common to the first embodiment and the second embodiment:

[0065] As a new implementation manner, in combination with the attached Figure 7 , the bottom surfaces of the outer frame 41 and the light-blocking sheet 42 are both in contact with the first light source substrate 1. The outer frame 41 is a ring, one end of the light-blocking sheet 42 is connected to the outer frame 41, and the height of the light-blocking sheet 42 tends to be the same as the height of the outer frame 41; the outer diameter of the outer frame 41 is slightly smaller than the outer diameter of the first light source substrate 1, and a plurality of mounting holes for fixing the light-blocking member are also provided on the outer frame 41, so that the light-blocking member 4 can be installed on the first light source substrate 1. The beneficial effect of this implementation manner is to prevent the light emitted by the first light source 11 from leaking out through the gap between the bottom surfaces of the outer frame 41 and the light-blocking sheet 42 and the first light source substrate 1; the light of the formed windmill lighting effect is clearer.

[0066] As a new implementation manner, in combination with the attached Figure 7 , the relationship between the height H1 of the light-blocking member 4 and the distance H2 between the light-blocking member 4 and the light-emitting lens 3 is H1≥3*H2. When H1≤3*H2, that is, the distance H2 between the light-blocking member 4 and the light-emitting lens 3 is too large, at this time the light-blocking member 4 cannot effectively prevent the light of two adjacent light-emitting areas from mixing with each other, so the boundary line between the two formed lighting effects is not obvious; when H1≥3*H2, the greater the numerical difference between the height H1 of the light-blocking member 4 and the distance H2 between the light-blocking member 4 and the light-emitting lens 3, and the closer the distance H2 between the light-blocking member 4 and the light-emitting lens 3, the more obvious the boundary line between the lighting effects formed by two adjacent light-emitting areas. The beneficial effect of this implementation manner is that when H1≥3*H2, it can prevent the light from two light-emitting areas from interfering with each other, and there is an obvious boundary line between the formed lighting effects.

[0067] As a new implementation manner, in combination with the attached Figure 1 , the outer surface of the light-blocking sheet 42 is a mirror surface. One end of the light-blocking sheet 42 is connected to the outer frame, and the other end is connected to the adjacent light-blocking sheet 42, or is connected to other structures that are coaxial with the outer frame 41 and located in the middle of the outer frame 41; the inner surface of the outer frame 41 is also a mirror surface. The beneficial effect of this implementation manner is that the outer surface of the light-blocking sheet 42 and the inner surface of the outer frame 41 do not absorb the light emitted by the first light source 11, and do not cause large losses to the light emitted from the first light source 11; the outer surface of the light-blocking sheet 42 is a mirror surface, which is conducive to reflecting the light emitted by the first light source 11 in the mirror and concentrating it in the same direction, making the light of the first light source 11 more concentrated.

[0068] As one implementation method, when multiple independent light-emitting areas are controlled independently of each other:

[0069] Combined with Figure 2b , Attachment Figure 3d , Attachment Figure 4d , Attachment Figure 5d and attached Figure 6d , multiple independent light-emitting areas are controlled independently of each other. Multiple first light sources 11 in the same light-emitting area can also be controlled independently of each other or in groups. The first light source 11 in each independent light-emitting area adopts an RGB light source, so each independent light-emitting area can form a variety of color lighting effects through the RGB color mixing principle; it also includes the following two implementation forms:

[0070] The first implementation form: Figure 2b As shown, when the six spiral light-emitting areas 12 are controlled independently of each other, each spiral light-emitting area 12 can be lit at the same time, or only one, two, three, four or five can be lit individually; among which only one, two, three, four or five can be lit arbitrarily among the six spiral light-emitting areas 12; at this time, there are multiple lighting modes, when the six spiral light-emitting areas 12 are lit at the same time, the lights of the six spiral light-emitting areas 12 can be completely different colors, or several of the spiral light-emitting areas 12 can be the same color; when the lamp is working, different lights are changed clockwise or counterclockwise on the six spiral light-emitting areas 12.

[0071] The second implementation form: Figure 3d , Attachment Figure 4d , Attachment Figure 5d and attached Figure 6d As shown, the first light source 11 is divided into twelve independent light-emitting areas; when the twelve independent light-emitting areas are controlled independently of each other, each independent light-emitting area can be lit at the same time, or only one, two, three, four, five, six, seven, eight, nine, ten or eleven areas can be lit separately; the area to be lit separately can be selected arbitrarily from the twelve independent light-emitting areas; at this time, there are many light-emitting modes, which cannot be listed one by one, and only one light-emitting mode is listed below: when the twelve light-emitting areas are lit at the same time, the lights of the twelve light-emitting areas can be completely different colors, or they can be the same color; when the lamp is working, the lights of different colors on the twelve light-emitting areas are changed clockwise or counterclockwise in turn.

[0072] As attached Figure 4d As shown, when the first light source 11 is divided into ten independent light-emitting areas, the light-emitting manner in which each independent light-emitting area is independently controlled is the same as the above-mentioned light-emitting manner.

[0073] As another implementation, when multiple independent light-emitting regions are grouped and independently controlled, there are the following two implementation forms:

[0074] The first implementation form, as shown in the appendix Figure 2b When the six spiral light-emitting regions 12 are divided into three groups and independently controlled, the light-emitting mode at this time is that the two spiral light-emitting regions 12 in each group of two are synchronous; the two spiral light-emitting regions 12 in each group of two can be either two adjacent spiral light-emitting regions 12 as a group, or a pair of opposite spiral light-emitting regions 12 as a group, etc.; the light-emitting mode of each group can also be various. It can be that the three groups of spiral light-emitting regions 12 work simultaneously, and the light colors formed by the two spiral light-emitting regions 12 in each group of two are red, green, blue, etc., and the three different light colors will be alternately changed in a clockwise or counterclockwise order on the three groups of spiral light-emitting regions 12.

[0075] The second implementation form, when multiple independent light-emitting regions are grouped and independently controlled, there can be various different grouping modes, such as being divided into two groups, three groups, four groups, five groups or six groups, etc., which are endless; therefore, only one of the grouping modes of the light-blocking members 4 with four different shapes is listed below, that is, four modes:

[0076] Mode 1: As shown in the appendix Figures 3b to 3d The light-emitting region 131 is an ellipse, and the light-emitting region 141 is an ax shape; at this time, the independent light-emitting regions are divided into two groups, and each light-emitting region in each group is synchronous; that is, the light-emitting regions in the same group must emit light simultaneously, but the colors of the lights formed can be different; the light-emitting region group 13 is one group, and the light-emitting region group 14 is one group; the light-emitting modes of these two groups of light-emitting regions are various. For example, the two groups of light-emitting regions can emit light simultaneously or alternately; the color of the light effect formed by the light-emitting region group 13 is red, and the color of the light effect formed by the light-emitting region group 14 is green; it can be understood that the colors of the light effects formed by the two groups of light-emitting regions can also be other colors.

[0077] Mode 2: As shown in the appendix Figures 4b to 4dAs shown, the first light-emitting area 131 is trapezoidal, and the second light-emitting area 141 is fan-shaped. At this time, the independent light-emitting areas are divided into five groups, and each light-emitting area in each group is synchronized. That is, the light-emitting areas in the same group must emit light simultaneously, but the colors of the formed lights can be different. Among them, the first light-emitting area group 13 serves as a background light effect as one group, and the five fan-shaped light-emitting areas in the second light-emitting area group 14 are divided into two as one group, and the other three are each divided into three groups. The first light-emitting area group 13 is blue, the two light-emitting areas in one group of the second light-emitting area are orange, and the colors of the three single light-emitting area groups are cyan, green, and red respectively. It can be understood that the colors of the five groups of light-emitting areas can also be other colors. The light-emitting methods of these five groups of light-emitting areas are diverse. For example, the five groups of light-emitting areas can emit light simultaneously, and various different colors can be alternately changed clockwise or counterclockwise on the five groups of light-emitting areas. It can also be that the five groups of light-emitting areas emit light alternately in a clockwise or counterclockwise direction. It can also be that the first light-emitting area group 13 is always on, and the other four groups emit light alternately, etc.

[0078] Mode 3: As shown in the appendix Figures 5b to 5d As shown, the first light-emitting area 131 is diamond-shaped, and the second light-emitting area 141 is funnel-shaped. At this time, the independent light-emitting areas are divided into four groups, and each light-emitting area in each group is synchronized. That is, the light-emitting areas in the same group must emit light simultaneously, but the colors of the formed lights can be different. Among them, the first light-emitting area group 13 serves as a background light as one group, and the second light-emitting area group 14 is divided into two light-emitting areas as one group, that is, three groups. There are many ways of grouping. The two first light-emitting areas 131 in one group can be either every two adjacent first light-emitting areas 131 as one group, or a pair of opposite first light-emitting areas 131 as one group, etc. The color of the light effect of the first light-emitting area group 13 is blue, and the colors of the light effects of the other three groups of light-emitting areas are red, orange, and green respectively. It can be understood that the colors of the light effects of the four groups of light-emitting areas can also be other colors. The light-emitting methods of these four groups of light-emitting areas can be diverse. For example, the four groups of light-emitting areas can emit light simultaneously, and various different colors can be alternately changed clockwise or counterclockwise on the four groups of light-emitting areas. It can also be that the four groups of light-emitting areas emit light alternately in a clockwise or counterclockwise direction. It can also be that the first light-emitting area group 13 is always on, and the other three groups emit light alternately, etc.

[0079] Mode 4: As shown in the appendix Figures 6b to 6dAs shown, the first light-emitting area 131 is trapezoidal, and the second light-emitting area 141 is in the shape of a boot. At this time, the independent light-emitting areas are divided into four groups, and each light-emitting area in each group is synchronized. That is, the light-emitting areas in the same group must emit light simultaneously, but the colors of the formed lights can be different. The second light-emitting area group 14 is divided into three groups, with two light-emitting areas in each group, and the first light-emitting area group 13 serves as the background light and is in one group. The two light-emitting areas in a group can be any two in the second light-emitting area group 14. The color of the lighting effect of the first light-emitting area group 13 is cyan, and the colors of the other three groups are red, blue, and orange respectively. It can be understood that the colors of the lighting effects of the four groups of light-emitting areas can also be other colors. The lighting methods of these four groups of light-emitting areas can be diverse. For example, the four groups of light-emitting areas can emit light simultaneously, and various different colors can be cyclically changed clockwise or counterclockwise on the four groups of light-emitting areas; or the four groups of light-emitting areas can emit light alternately in the clockwise or counterclockwise direction; or the first light-emitting area group 13 can be constantly on, and the other three groups can emit light alternately, etc.

[0080] The beneficial effect of this embodiment is that it is conducive to forming a variety of different windmill rotation lighting effects, and the RGB color mixing technology is added, making the colors of the windmill rotation lighting effects more abundant.

[0081] As a new embodiment, in combination with the attached Figure 1 and the attached Figure 7 , it further includes a second light source substrate 2 located at the center of the first light source substrate 1, a second light source 21 provided on the second light source substrate 2, and a reflector cup 45 in contact with the second light source substrate 2. The first light source substrate 1 and the second light source substrate 2 are on the same plane. When the second light source 21 is an integrated surface light source, that is, a COB light source, etc., the first light source substrate 1 and the second light source substrate 2 are different parts on the same substrate; the second light source 21 is located at the center of the substrate, and the first light source 11 is located outside the second light source 21 and is distributed around the center of the substrate. At this time, since the second light source 21 is a COB light source, the light source substrate needs to be customized in order to install other point light sources on the COB light source substrate; or when the second light source 21 is also a point light source, the first light source substrate 1 and the second light source substrate 2 are different parts on the same substrate, and the light source substrate does not need to be customized. The first light source substrate 1 and the second light source substrate 2 are on different planes. This is the common practice in the industry, and the light source substrate does not need to be customized when the second light source 21 is a COB point light source. At this time, a circular through hole is provided at the center of the first light source substrate 1, and its diameter is greater than the diameter of the second light source 21; the second light source substrate 2 is located below the first light source substrate 1, and the reflector cup 45 passes through the circular through hole of the first light source substrate 1 and is in contact with the second light source substrate 2, which is beneficial to preventing the phenomenon of light crosstalk in the light emitted by the second light source 21. The beneficial effect of this embodiment is that it adds a light-emitting center to the lamp with a windmill rotation lighting effect, making the lighting effect level of the lamp more abundant.

[0082] As a new implementation manner, in combination with the attached Figure 2a , the attached Figure 3a , the attached Figure 4a , the attached Figure 5a and the attached Figure 6a , the reflector cup 45 and the light cutoff member 4 are integrally formed, and the reflector cup 45 is located in the middle of the light cutoff member 4. One end of the light cutoff piece 42 is connected to the outer frame 41, and the other end is connected to the reflector cup 45. When the first light source substrate 1 and the second light source substrate 2 are not in the same plane, the height of the reflector cup 45 is greater than the height of the light cutoff piece 42 and the outer frame 41, and the light incident surface of the reflector cup 45 and the bottom surface of the light cutoff piece 42 are not in the same plane; when the first light source substrate 1 and the second light source substrate 2 are in the same plane, the height of the reflector cup 45 is equal to the height of the light cutoff piece 42 and the outer frame 41, and the light incident surface of the reflector cup 45 and the bottom surface of the light cutoff piece 42 are in the same plane. The beneficial effect of this implementation manner is that the reflector cup 45 and the light cutoff member 4 are integrally formed, which is more convenient for installation and can effectively save costs; the reflector cup 45 being located in the middle is beneficial to forming a more coordinated lighting effect.

[0083] As a new implementation manner, in combination with the attached Figure 1 , the light-emitting lens 3 is a Fresnel lens. The center of the Fresnel lens is a convex lens, and the periphery of the convex lens is a serrated concentric circle pattern; a diffusion sheet 5 that can completely cover the first light source 11 and the second light source 21 is also installed below the Fresnel lens, which can make the formed lighting effect softer and can effectively hide the lamp bead shapes of the first light source 11 and the second light source 21. The beneficial effect of this implementation manner is that the serrated concentric circle pattern part of the Fresnel lens can make the lighting effect formed by the first light source 11 more beautiful; the convex lens in the center of the Fresnel lens can make the light emitted by the second light source 21 more concentrated, having a light-gathering effect.
