[0034] In the embodiment of this application, Figure 1-Figure 3 The candle flame-shaped profiling portion 12 is taken as an example to illustrate various structural positions, but the light emitting module 20 in this application is not limited to be used only on the candle flame-shaped profiling portion 12 .

[0035] Please also refer to Figures 1 to 5The contoured lighting fixture provided by the present invention is now described. The contoured lighting fixture includes a carrier 10, a light-emitting module 20, a circuit module 30, and a lampshade 40. The carrier 10 includes a power supply portion 11 and a contoured portion 12 located above the power supply portion 11. The contoured portion 12 includes multiple light-emitting modules 20, each including at least one light-emitting element 21. All light-emitting elements 21 within the same light-emitting module 20 are electrically connected. The circuit module 30 includes a cathode access point 31 and multiple anode access points 32, or an anode access point 32 and multiple cathode contact points. The lampshade 40 is disposed on the outer periphery of the carrier 10, and the shape of the lampshade 40 is adapted to the shape of the contoured portion 12.

[0036] When the circuit module 30 includes multiple anode access points 32 , the multiple anode access points 32 are conductively connected to the multiple light-emitting modules 20 in a one-to-one correspondence; when the circuit module 30 includes multiple cathode access points 31 , the multiple cathode access points 31 are conductively connected to the multiple light-emitting modules 20 in a one-to-one correspondence.

[0037] It should be noted that the shape of the contoured portion 12 can be a candle shape, a flying bird shape, a penguin shape, etc., and the shape of the corresponding lampshade 40 is also the same three-dimensional shape as the contoured portion 12 .

[0038] An example of a lighting method of the contour lighting fixture provided in this embodiment is as follows:

[0039] (1) All light-emitting modules 20 are turned on and off at the same time;

[0040] (2) There are P light-emitting modules 20. The first light-emitting module 20 is first lit, then the first light-emitting module 20 is turned off and the second light-emitting module 20 is turned on. Then the second light-emitting module 20 is turned off and the third light-emitting module 20 is turned on. And so on, the cycle continues to the Pth light-emitting module. The lighting duration of each light-emitting module 20 and the lighting interval between two adjacent light-emitting modules 20 can be adjusted according to needs.

[0041] (3) There are P light-emitting modules 20. The first light-emitting module 20 is lit, then the second light-emitting module 20 is lit, then the third light-emitting module 20 is lit, and so on until all the light-emitting modules 20 are lit, and then all are turned off and the lighting process is repeated. The lighting interval time of two adjacent light-emitting modules 20 can be adjusted according to needs;

[0042] (4) There are P light-emitting modules 20. The first light-emitting module 20 is lit, then the second light-emitting module 20 is lit, then the third light-emitting module 20 is lit, and so on until all the light-emitting modules 20 are lit. Then, they are turned off one by one in reverse order until all the light-emitting modules 20 are turned off and the lighting process is repeated. The interval time between the lighting or turning off of two adjacent light-emitting modules 20 can be adjusted according to needs;

[0043] (5) There are P light-emitting modules 20. The first n (n≥2) light-emitting modules 20 are lit at the same time. Then, n light-emitting modules 20 are lit one by one in a group until all the light-emitting modules 20 are lit. Then, all are turned off and the lighting process is repeated. The time interval between the lighting of adjacent groups can be adjusted according to needs.

[0044] Compared with the prior art, when the multiple light-emitting modules 20 of the contoured lighting fixture of the present invention are electrically connected one-to-one with multiple cathode access points 31, the multiple light-emitting modules 20 share a cathode; when the multiple light-emitting modules 20 are electrically connected one-to-one with multiple anode access points 32, the multiple light-emitting modules 20 share an anode; by setting multiple anode access points 32 or multiple cathode access points 31, the multiple light-emitting modules 20 can be controlled separately, thereby realizing a variety of lighting modes. In conjunction with the shape of the contoured portion 12, the distribution of the light-emitting modules 20 on the contoured portion 12 is adapted to its shape, thereby realizing a variety of dynamic effects when lighting or closing, such as the gradual ignition of a candle flame when it is lit, and the shaking effect during the lighting process. The simulation effect is more vivid, which increases the demand for application scenarios.

[0045] In some embodiments, an improved embodiment of the above-mentioned contoured portion 12 can be adopted as follows Figures 1 to 3 The structure shown. Figures 1 to 3 The light-emitting modules 20 are distributed on at least one of the front and back sides of the contoured portion 12. The carrier 10 is a plate-shaped structure. The light-emitting modules 20 can be arranged on only one side of the contoured portion 12 or on both sides to meet different lighting requirements. Furthermore, when light-emitting modules 20 are arranged on both sides, the light-emitting modules 20 on each side can also be controlled separately, thereby providing different lighting effects from the front and back sides.

[0046] In some embodiments, a specific arrangement of the light emitting module 20 can be as follows: Figures 1 to 3 The structure shown. Figures 1 to 3 The multiple light-emitting modules 20 located on the same surface of the shaped portion 12 are arranged in intervals from top to bottom. For example, if the shaped portion 12 is in the shape of a candle flame, the multiple light-emitting modules 20 are arranged in intervals from top to bottom. They can be lit together or one by one. When lighting one by one, lighting them one by one from bottom to top can simulate the process of candle lighting, which is closer to the actual shape of a candle flame. In addition, the multiple light-emitting modules 20 are arranged in intervals in the vertical direction, which can also facilitate the arrangement of the light-emitting modules 20 on the shaped portion 12 and make the wiring more reasonable.

[0047] As a variation, the multiple light-emitting modules 20 located on the same surface of the profiling portion 12 can be arranged irregularly. According to the specific shape of the profiling portion 12, the multiple light-emitting modules 20 are arranged according to the shape of the profiling portion 12, which can present a more vivid dynamic effect when lighting up one by one.

[0048] In some embodiments, a specific embodiment of the light emitting module 20 can be as follows: Figures 1 to 3 The structure shown. Figures 1 to 3 The multiple light-emitting bodies 21 in each light-emitting module 20 are arranged in a stair-like manner. Each light-emitting module 20 includes at least three light-emitting bodies 21. For example, when there are exactly three light-emitting bodies 21, the line connecting the three light-emitting bodies 21 forms a triangle, which is a stair-like arrangement. Similarly, the multiple light-emitting bodies 21 in the same light-emitting module 20 are arranged in a stair-like manner, and when they are lit one by one, they can also show a stair-like effect.

[0049] Specifically, the light emitting module 20 located at the front is stepped upward (see Figure 2 ), the light emitting module 20 on the reverse side faces downward (see Figure 3 The steps on the front and back sides have different orientations, which can ensure that the orientation of the entire lamp is the same, but different effects can be observed from different angles, simulating the effect that the shapes of objects seen from different perspectives during actual observation are different; however, when the profiling portion 12 is axially symmetrical, the shape seen from different orientations is the same.

[0050] It should be noted that the shapes of the multiple light-emitting bodies 21 in each light-emitting module 20 are not limited to regular stepped shapes, but may also be irregular stepped shapes, or may be a superposition of multiple stepped shapes.

[0051] In some implementations, a specific embodiment of the carrier 10 may have the following structure, where the carrier 10 is one of a ceramic, a glass fiber board, and an aluminum substrate.

[0052] When the carrier 10 is ceramic, it is a ceramic substrate. A ceramic substrate refers to a special process board in which copper foil is directly bonded to the surface (single or double sides) of an alumina or aluminum nitride ceramic substrate at high temperature. The resulting ultra-thin composite substrate has excellent electrical insulation properties, high thermal conductivity, excellent soft solderability and high adhesion strength. It can also be etched with various patterns like a PCB board and has a large current carrying capacity.

[0053] The glass fiber board is a glass fiber board, which is composed of glass fiber material and a high heat-resistant composite material. It has good heat insulation and flame retardant properties, can carry multiple light-emitting bodies 21 for light-emitting use at the same time, and can also reduce the probability of overheating damage.

[0054] The aluminum substrate has a good heat dissipation function. The aluminum substrate is generally composed of a three-layer structure: a circuit layer (copper foil), an insulating layer, and a metal base layer. The light-emitting body 21 is set on the aluminum substrate. The aluminum substrate can dissipate heat during the operation of the light-emitting body 21, thereby extending its service life.

[0055] In some embodiments, an improved embodiment of the carrier 10 may be as follows: Figure 5 The structure shown. Figure 5 The profiling portion 12 is provided with a plurality of profiling portions 12, and the plurality of profiling portions 12 enclose a polyhedron. For example, the plurality of profiling portions 12 enclose a regular polyhedron or an irregular polyhedron in the shape of a cone, a cylinder, a triangular pyramid, etc. The polyhedron includes a plurality of faces, each of which is composed of a profiling portion 12. Therefore, when lighting, the plurality of profiling portions 12 can be selected to light up one by one, thereby presenting a dynamic change effect, such as the process of a rabbit jumping, etc. This structure can present a richer dynamic effect.

[0056] In some implementations, a modified embodiment of the above-mentioned carrier 10 may be as follows: Figure 4 The structure shown. Figure 4 The profiling portion 12 is provided with a plurality of profiling portions 12, and the plurality of profiling portions 12 are arranged in parallel and at intervals. The plurality of profiling portions 12 are arranged in a queue, and the plurality of profiling portions 12 can be provided with the same shape or different shapes, thereby presenting effects such as a candle pile or a screen.

[0057] In some implementations, a specific embodiment of the light-emitting element 21 can employ the following structure: the light-emitting element 21 includes a light-emitting chip and fluorescent glue coated around the periphery of the light-emitting chip. The light-emitting chip can emit blue, red, or green light, and the fluorescent glue is a glue mixed with phosphor support. By coating the periphery of the light-emitting chip with fluorescent glue, the light-emitting element 21 can achieve a more vivid light-emitting effect and optimize the color characteristics of the light-emitting shape.

[0058] As another embodiment, the light emitting body 21 may also be a small packaged light source that emits white light.

[0059] Specifically, the multiple light-emitting bodies 21 in the same light-emitting module 20 may emit light of the same or different colors.

[0060] In some embodiments, a specific embodiment of the lampshade 40 can employ the following structure: the lampshade 40 is a colorless or colored silicone member. Colorless silicone is pure silicone; colored silicone is a mixture of phosphor and silicone of the corresponding color. Alternatively, the lampshade 40 may be made of other small particles that reflect or diffuse light. The material of the lampshade 40 can blur the edges and corners of the contoured portion 12, thereby more closely resembling the actual shape.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
