Detailed Embodiment
[0021] Combined with the attached Figure 1 and the attached Figure 2, A lamp with a special lighting effect, comprising an annular first light source substrate 1, multiple first light sources 11 provided 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 identical independent light emitting regions 12 and preventing cross-lighting. The light blocking sheets 42 are arranged radially, evenly spaced, and vertically around the center of the first light source substrate 1. It also includes an effect sheet 5 for making the emitted light have a certain effect; the first light source substrate 1, the light blocking member 4, the effect sheet 5, and the light output lens 3 are coaxially installed in sequence; the light blocking member 4 is provided with multiple fixing holes 411 for installing the light blocking member 4, and the light blocking member 4 is installed on the first light source substrate 1 through fixing members; the first light source substrate 1 is provided with multiple through holes adapted to the fixing holes 411 of the light blocking member 4; the shape of the effect sheet 5 is adapted to the shape of the light blocking member 4, and the effect sheet 5 is a circular sheet; the light blocking sheet 42 is a rectangular flat plate, and the light blocking sheet 42 is perpendicular to the first light source substrate 1; the multiple light blocking sheets 42 divide the first light source 11 into multiple fan-shaped independent light emitting regions 12; the beneficial effect of this embodiment is that the light blocking sheet 42 divides the first light source 11 into multiple independent fan-shaped light emitting regions 12, so that the multiple independent fan-shaped light emitting regions 12 can form a special lighting effect under a certain control method; and due to the blocking of the light blocking sheet 42, a distinct dividing line can be formed between the lighting effects formed by every two adjacent fan-shaped light emitting regions 12, and there will be no phenomenon of light mixing between the lighting effects formed by every two adjacent independent light emitting regions 12.
[0022] As a new embodiment, in combination with the attached Figure 2, the multiple independent light-emitting regions 12 include a plurality of light-emitting units 124, and the light-emitting units 124 include a plurality of first light sources 11. The multiple light-blocking sheets 42 are rectangular flat plates with the same shape, and divide the first light sources 11 into a plurality of fan-shaped light-emitting regions 12 with equal areas; thus, the number of light-emitting units 124 in each fan-shaped light-emitting region 12 is equal, and the total number of first light sources 11 in each fan-shaped light-emitting region 12 is also equal; the shape of the light-emitting unit 124 is set according to the shape of the light-blocking sheet 42 within the same light-emitting region 12 and relatively close to the light-emitting unit 124; therefore, the first light sources 11 within the same light-emitting unit 124 are also arranged according to the shape of the light-blocking sheet 42. Of course, the arrangement of the first light sources 11 also needs to achieve a uniform light-emitting effect. In this embodiment, a group of fan-shaped light-emitting regions 12 includes six independent fan-shaped light-emitting regions 12, and one fan-shaped light-emitting region 12 includes three light-emitting units 124; among them, two light-emitting units 124 are provided with two first light sources 11, and the other light-emitting unit 124 is provided with one first light source 11; the number and area of the fan-shaped light-emitting regions 12 are related to the volume of the lamp. When the volume of the lamp increases, the number of fan-shaped light-emitting regions 12 increases; or the number of fan-shaped light-emitting regions 12 remains unchanged but the area increases. At this time, the number of first light sources 11 in each fan-shaped light-emitting region 12 will also increase accordingly; when the volume of the lamp decreases, the number of fan-shaped light-emitting regions 12 decreases; or the area decreases. At this time, the number of first light sources 11 in each fan-shaped light-emitting region 12 decreases accordingly; it can be understood that the number of fan-shaped light-emitting regions 12 can also be seven, eight, nine, etc., the number of light-emitting units 124 located in the fan-shaped light-emitting region 12 can also be four, five, six, etc., and the number of first light sources 11 can also be three, four, five, etc.; the lighting effect formed by a group of fan-shaped light-emitting regions 12 is a special lighting effect, which has a great relationship with the radially arranged fan-shaped light-emitting regions 12. The beneficial effect of this embodiment is that the first light sources 11 of the multiple light-emitting units 124 can be controlled individually, or grouped according to the light-emitting units 124, or not grouped according to them. The colors of the formed lighting effects are colorful; under a certain control method, a group of fan-shaped light-emitting regions 12 can form a special light-emitting effect. For example, a light-emitting effect similar to the rotation of a windmill.
[0023] As a new embodiment, in combination with the attached Figure 3, the bottom surfaces of the outer frame 41 and the light intercepting piece 42 are both in contact with the first light source substrate 1. The outer frame 41 is a circular ring, one end of the light intercepting piece 42 is connected to the outer frame 41, and the height of the light intercepting piece 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 the outer frame 41 is also provided with a plurality of fixing holes 411 for installing the light intercepting piece 42, so that the light intercepting piece 4 can be installed on the first light source substrate 1. The beneficial effect of this embodiment is to prevent the light emitted by the first light source 11 from leaking through the gap between the bottom surfaces of the outer frame 41 and the light intercepting piece 42 and the first light source substrate 1; making the light of the formed lighting effect clearer.
[0024] As a new embodiment, in combination with the attached Figure 3 , the relationship between the height H1 of the light intercepting piece 4 and the distance H2 between the light intercepting piece 4 and the light emitting lens 3 is H1≥3*H2. When H1≤3*H2, that is, the distance H2 between the light intercepting piece 4 and the light emitting lens 3 is too large, at this time the light intercepting piece 4 cannot effectively prevent the light of two adjacent light emitting regions 12 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 intercepting piece 4 and the distance H2 between the light intercepting piece 4 and the light emitting lens 3, and the closer the distance H2 between the light intercepting piece 4 and the light emitting lens 3, the more obvious the boundary line between the lighting effects formed by two adjacent light emitting regions 12. The beneficial effect of this embodiment is that when H1≥3*H2 is satisfied, it can prevent the light from stringing between the two light emitting regions 12, and there is an obvious boundary line between the formed lighting effects.
[0025] As a new embodiment, in combination with the attached Figure 2 , the outer surface of the light intercepting piece 42 is a mirror surface. One end of the light intercepting piece 42 is connected to the outer frame 41, the other end is connected to the adjacent light intercepting piece 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 embodiment is that the outer surface of the light intercepting piece 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 intercepting piece 42 is a mirror surface, which is beneficial to concentrating the light emitted by the first light source 11 in the same direction after mirror reflection, making the light of the first light source 11 more concentrated.
[0026] In terms of the control methods of multiple independent light emitting regions, there are the following two embodiments: Embodiment 1
[0027] In combination with the attached Figure 2 and the attached Figure 4, multiple independent light-emitting areas 12 are controlled independently of each other. Multiple first light sources 11 in the same light-emitting area 12 can also be controlled independently of each other or in groups. The first light source 11 in each independent light-emitting area 12 adopts an RGB light source, so each independent light-emitting area 12 can form a variety of color lighting effects through the RGB color mixing principle; as shown in the attached Figure 4 As shown, when the six fan-shaped light-emitting areas 12 are controlled independently of each other, each fan-shaped light-emitting area 12 can be lit at the same time, or only one, two, three, four or five can be lit separately; among which only one, two, three, four or five can be lit separately, which can be arbitrarily selected from the six fan-shaped light-emitting areas 12; at this time, there are multiple light-emitting modes, when the six fan-shaped light-emitting areas 12 are lit at the same time, the lights of the six fan-shaped light-emitting areas 12 can be completely different colors, or several of the fan-shaped light-emitting areas 12 can be the same color; when the lamp is working, different lights are changed clockwise or counterclockwise on the six fan-shaped light-emitting areas 12. The beneficial effect of embodiment 1 is that it is conducive to forming a variety of different lighting effects, and the RGB color mixing technology is added, and the color of the lighting effect is richer. Embodiment 2
[0028] The difference between the second embodiment and the first embodiment is that the control method of the multiple independent light-emitting areas is different. Figure 5As shown, the fan-shaped light-emitting area 12 can be divided into two groups, three groups, four groups, etc. Each light-emitting area 12 in each group is synchronous; that is, the light-emitting areas 12 in the same group must emit light simultaneously, but the colors of the formed lights can be different; there are many ways to group them. Taking a group of fan-shaped light-emitting areas 12 divided into three groups as an example, a group of fan-shaped light-emitting areas 12 includes the first light-emitting area group 121, the second light-emitting area group 122, and the third light-emitting area group 123; among them, two fan-shaped light-emitting areas 12 in a group can be either two adjacent fan-shaped light-emitting areas 12 in a group or a pair of opposite fan-shaped light-emitting areas 12 in a group, etc.; the color of the lighting effect of the first light-emitting area group 121 is blue, and the colors of the lighting effects of the second light-emitting area group 122 and the third light-emitting area group 123 are red and green respectively; it can be understood that the colors of the lighting effects of the three light-emitting areas (121, 122, 123) can also be other colors; the lighting methods of these three light-emitting areas (121, 122, 123) can be various; for example, the three light-emitting areas (121, 122, 123) can emit light simultaneously, the three light-emitting areas (121, 122, 123) can emit light simultaneously in a clockwise or counterclockwise direction and alternately change multiple different colors; it can also be that the three light-emitting areas (121, 122, 123) emit light alternately in a clockwise or counterclockwise direction; it can also be that the first light-emitting area group 121 is always on, and the other two groups emit light alternately, etc. The beneficial effect of the second embodiment is that it is conducive to forming a variety of different lighting effects, and the RGB color mixing technology is added, and the colors of the lighting effects are more abundant.
[0029] Based on the above-mentioned first embodiment and second embodiment, there are also the following implementation methods common to the first embodiment and the second embodiment:
[0030] As a new implementation method, in combination with the attached Figure 1 and the attached Figure 3, further including a second light source substrate 2 located at the center of the first light source substrate 1, a second light source 21 disposed on the second light source substrate 2, and a reflecting cup 43 abutting against the second light source substrate 2. The first light source substrate 1 and the second light source substrate 2 are on the same plane. 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 distributed around the center of the substrate; 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. At this time, a circular through hole is provided at the center of the first light source substrate 1, and its diameter is larger than the diameter of the second light source 21; the first light source substrate 1 is an annular flat plate, and the second light source substrate 2 is located at the center of the first light source substrate 1; the second light source 21 is located at the center of the second light source substrate 2, and the first light source 11 is located outside the second light source 21 and evenly distributed around the center of the first light source substrate 1; and the second light source substrate 2 is installed below the first light source substrate 1, and the reflecting cup 43 passes through the circular through hole of the first light source substrate 1 and abuts against the second light source substrate 2, which is beneficial to preventing the light emitted by the second light source 21 from being cross-lighted. The beneficial effect of this embodiment is that it adds a luminous center for the lamp with a special luminous effect, making the lighting effect of the lamp more rich in levels.
[0031] As a new embodiment, in combination with the attached Figure 1 , the second light source 21 is a laser light source or an integrated surface light source. When the second light source 21 is a laser light source, the common practice in the industry is that the first light source substrate 1 and the second light source substrate 2 are different parts of the same light source substrate; the laser light source used is a chip-type laser light source, and its size is similar to that of an ordinary point light source; the second light source 21 can be composed of multiple chip-type laser light sources, and the lighting effect formed by the chip-type laser light sources is a beam of parallel light. When the second light source 21 is an integrated surface light source, that is, the second light source 21 is a COB light source; the common practice is that the first light source substrate 1 and the second light source substrate 2 are two separate light source substrates; if the first light source substrate 1 and the second light source substrate 2 are to be different parts of the same light source substrate, the COB light source substrate needs to be customized to install other point light sources on the COB light source substrate; the light emitted by the COB light source is more uniform, without obvious light spots or dark areas. The beneficial effect of this embodiment is that it increases the selectivity of the second light source 21, and customers can choose different light sources according to their needs; the lighting effects formed by the two different light sources are also different, making the lighting effect of the lamp more rich in levels.
[0032] As a new embodiment, 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 serrated concentric circular patterns; a diffuser sheet 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 embodiment is that the serrated concentric circular 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, with a light-gathering effect.
