[0002] An omnidirectional luminaire with no dark areas is a lighting device that uses a translucent luminous material lamp housing to spread the light of the LED lamp in the lamp housing in all directions of the lamp housing, pursuing multi-angle lighting. At present, in order to achieve multi-angle light transmission of the lamp housing, the main method used is to enlarge the internal space of the lamp housing, and then spread the light of the LED lamp in all directions of the lamp housing through the internal space of the lamp housing. However, in order to make the light emission as uniform as possible, the internal space of the lamp housing needs to be as large as possible, resulting in a large overall volume of the luminaire, which cannot be adapted to the volume requirements of various lamps. Moreover, when the light is transmitted by the internal space of the lamp housing alone, the problem of uneven light emission is still obvious due to the limitation of the light emission direction of the LED lamp.

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar methods or methods having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limitations of the present invention. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 2 The embodiment of the present invention provides an omnidirectional luminaire without dark areas, comprising: A light-transmitting lamp body shell, the light-transmitting lamp body shell is an external light propagation layer for propagating the light of the LED lamp of the lamp, and a transparent wick shell is arranged inside the light-transmitting lamp body shell, and the transparent wick shell is used to propagate the light of the LED lamp of the lamp to the external light propagation layer; A transparent wick shell, which is an internal light propagation layer for propagating the light of the LED lamp of the lamp, and comprises a transparent wick shell body and a plurality of transparent convex surfaces spaced apart on the outer wall of the transparent wick shell body, wherein the plurality of transparent convex surfaces and the transparent wick shell body together form the internal light propagation layer; The LED lamp wick is arranged inside the transparent lamp wick shell; the light-emitting surface of the LED lamp wick faces the inner wall of the transparent lamp wick shell body, emitting the LED light of the lamp, and the LED light of the lamp penetrates the transparent lamp wick shell body and propagates toward the inner wall of the translucent lamp body shell via the outer wall of the transparent lamp wick shell body and the multiple transparent protrusions.

[0021] It should be noted that in this embodiment, by setting the lamp to include both a transparent wick shell and a translucent lamp body shell, two inner and outer light propagation layers are formed. The light emitted by the LED wick first passes through the transparent wick shell, and then further propagates to the outer translucent lamp body shell, and finally emits to the outside. In this way, the LED light can be diffused in the inner layer, and further evenly scattered in all directions through the outer layer, thereby improving the uniformity of light output and reducing dependence on internal space. At the same time, since there is no need to excessively expand the overall volume of the lamp shell, it also makes the lamp easier to adapt to various size requirements, fundamentally solving technical problems such as large volume, uneven light emission, and poor adaptability of traditional lamps. The design of layered propagation of inner and outer shells can not only enhance the uniformity of light distribution at different angles, but also maintain the flexibility and controllability of the shape and volume of the lamp.

[0022] It should also be noted that in this embodiment, when the light emitted by the LED wick penetrates the transparent wick shell body, the light will produce further refraction, scattering or microlens effect when it contacts the raised surface on the transparent wick shell body, thereby dispersing the light more in different directions. Compared with the traditional method of relying solely on light passing through a uniform and flat outer wall, these raised surfaces on the outer wall of the transparent wick shell body in this embodiment can provide multiple refraction / scattering interfaces, reducing uneven brightness, dark areas or striped light effects caused by unidirectional or limited angle light emission of the LED. In other words, these raised surfaces on the outer wall of the transparent wick shell body can act as multi-level diffusion parts in the internal light propagation layer, dispersing the light in the relatively concentrated area of ​​light intensity to a wider angle range, so that a more uniform illumination distribution is obtained in all directions around the lamp body, thereby significantly improving the overall luminous uniformity of the lamp, reducing dark areas, and achieving a softer, all-round lighting effect.

[0023] In some preferred embodiments, the plurality of transparent raised surfaces are arranged at equal intervals and are distributed at intervals on the outer wall of the transparent wick shell body to form a plane or a curved surface for propagating the light of the LED lamp of the lamp. It should be noted that in the present embodiment, the plurality of transparent raised surfaces are distributed at equal intervals and at intervals on the outer wall of the transparent wick shell body to form a plane or a curved surface, thereby further improving the effect of uniform light propagation. When the light of the LED wick penetrates the transparent wick shell body, the light will produce a refraction or scattering effect when it encounters the raised surface on the outer wall, which helps to distribute the light to more angles, thereby avoiding the occurrence of blind spots or dark areas of illumination. The equally spaced distribution of the raised surfaces also facilitates the segmentation and multiple scattering of the lamp in the overall space, making the light intensity distribution more uniform. In addition, the raised surface can be a plane or a curved surface, and can be designed according to different application requirements or lighting effects, so as to achieve the goal of omnidirectional luminescence and no dark areas without significantly increasing the volume of the shell.

[0024] In some preferred embodiments, when the lamp is produced, the transparent wick shell is generated by extruding a silicone material in an extruder, so that the transparent wick shell forms the transparent wick shell body and the multiple transparent raised surfaces. It should be noted that the silicone material has excellent optical transmittance and high temperature resistance, and through extrusion molding, the overall structure of the transparent wick shell body and the multiple transparent raised surfaces can be formed at one time, reducing the subsequent assembly and processing steps, and achieving stability and consistency in mass production. At the same time, the flexibility and plasticity of the silicone material can better realize the refraction and scattering of light at the transparent raised surfaces, helping to further improve the uniformity of light propagation of the lamp.

[0025] In some preferred embodiments, when the lamp is produced, the translucent lamp body shell is generated by extruding a silicone material in an extruder. It should be noted that in this embodiment, the outer layer of the translucent lamp body shell is also completed by silicone extrusion molding. On the one hand, this can ensure the material compatibility between the translucent lamp body shell and the transparent wick shell, so that the optical properties of the internal and external light propagation layers of the entire lamp are consistent; on the other hand, the extrusion molding method is also conducive to the mass production and adjustable size of the translucent lamp body shell, so as to better adapt to the needs of lamps of different shapes or sizes. Since the material itself has a certain degree of flexibility and plasticity, the translucent lamp body shell can be designed into different shapes or thicknesses according to lighting requirements, which greatly improves the design freedom and adaptability of the product, and helps the lamp to achieve omnidirectional light emission while maintaining a controllable volume.

[0026] In some preferred embodiments, the transparent wick shell is a cavity structure, and the LED wick is arranged in the cavity inside the cavity structure, and is limited and fixed by the cavity inside the cavity structure. It should be noted that placing the LED wick directly in the cavity of the transparent wick shell can keep the LED wick in a stable position due to the limitation of the shell structure, avoiding shaking or deviation during the use or transportation of the lamp. At the same time, the cavity design allows the LED light to be evenly refracted / scattered in the transparent wick shell before entering the external translucent lamp body shell, greatly improving the overall uniformity of light emission. In addition, using a cavity to place the LED wick can also allow the interior of the transparent wick shell to have a relatively fixed spatial structure, which is conducive to mass production.

[0027] In some preferred embodiments, the cavity structure includes an LED wick installation cavity and a cavity upper part, a cavity lower part, a cavity left part, and a cavity right part that form the LED wick installation cavity; the cavity upper part and the cavity lower part are mutually symmetrical symmetrical structures, and the cavity left part and the cavity right part are mutually symmetrical symmetrical structures; after the LED wick is installed in the LED wick installation cavity, the light-emitting surface of the LED wick faces the inner wall of the cavity upper part and / or the cavity lower part. It should be noted that in this embodiment, the cavity structure includes an LED wick installation cavity and a symmetrical structure of a cavity upper part, a cavity lower part, a cavity left part, and a cavity right part, and the light-emitting surface of the LED wick faces the inner wall of the cavity upper part and / or the cavity lower part. This cavity design that is symmetrical up and down and left and right can evenly distribute the light of the LED chip, and with the refraction and scattering functions of the transparent convex surface and the transparent wick shell body, the lamp body can obtain a more uniform light distribution in all directions. At the same time, if the light-emitting surface of the LED wick faces upward or downward, the convex curved surface or flat surface on the transparent wick shell body can be effectively used to guide and diffuse the light. Such a multi-faceted cavity structure can not only allow the LED wick to be tightly installed and prevent shaking, but also form a uniform and multi-angle light propagation path around the wick, achieving light emission without dark areas of the lamp.

[0028] In some preferred embodiments, the LED wick is an LED flexible light strip. After the LED flexible light strip is installed in the LED wick installation cavity, the lamp bead distribution surface of the LED flexible light strip faces the inner wall of the upper part of the cavity and / or the lower part of the cavity. It should be noted that the flexible light strip has the advantages of being bendable and customizable in length, and is more easily adapted to wick cavities of various shapes and sizes. By aligning the lamp bead distribution surface with the inner wall of the upper or lower part of the cavity, the light can be concentrated and scattered in the direction of the two major surfaces of the transparent wick shell, and then refracted multiple times by the convex surface on the transparent wick shell to obtain a more uniform lighting effect. For lighting devices that want to achieve uniform and omnidirectional light output in a smaller volume, flexible light strips can effectively arrange more LED light-emitting points, which helps to solve the technical problems of wick design and space limitations, while maintaining the compactness of the overall lamp structure and uniform light distribution. Furthermore, when the bead distribution surface of the LED flexible light strip faces the inner wall of the upper part of the cavity and / or the lower part of the cavity, there is no direct contact with the inner wall of the upper part of the cavity and / or the lower part of the cavity. It should be noted that when the bead distribution surface of the LED flexible light strip directly contacts the upper or lower inner wall of the cavity, it is easy to cause the bead to be partially blocked or squeezed, causing the light to be unable to fully diverge, and then produce uneven brightness or dark spots; at the same time, it will also bring potential heat accumulation and mechanical damage problems. Since LED lamp beads require a certain space to ensure normal heat dissipation and optical emission effects, if the lamp beads are close to the inner wall of the shell, it may not be able to form an effective scattering path, reducing the uniformity of the overall lighting. Furthermore, the flexible light strip will be subject to certain bending or vibration during installation and later use. If it is in direct contact with the inner wall, it is very easy to cause friction or looseness, thereby affecting the stability and service life of the LED lamp beads. In this embodiment, by keeping a certain distance between the lamp bead distribution surface and the inner wall, not only can the LED lamp beads be protected from physical damage, but also a stable optical refraction / scattering space can be formed, so that the lamp can achieve more uniform omnidirectional light output in a smaller volume. Further, when the lamp bead distribution surface of the LED flexible light strip faces the inner wall of the upper part of the cavity and / or the lower part of the cavity, the shape of the inner wall of the upper part of the cavity and / or the lower part of the cavity is a curved surface with the concave surface facing the lamp bead distribution surface of the LED flexible light strip. It should be noted that the concave shape can better propagate the outgoing light. When the light emitted by the LED lamp beads shines on the concave inner wall, the concave inner wall can make more light produce controlled diffuse reflection or refraction inside, avoiding direct light or deflection to the dead corner, not only increasing the propagation path of the light in the cavity, but also diffusing part of the light to a wider range, thereby reducing the dark area and improving the uniformity of the light. In addition, the concave surface facing the LED light strip means that a certain distance will be maintained between the inner wall and the lamp beads everywhere, so that the LED lamp beads will not be in direct contact with the inner wall. This not only provides a better heat dissipation channel for the lamp beads, but also prevents mechanical damage caused by collision, bending, etc.The curved shape can also evenly share the pressure on the flexible light strip, reduce local stress concentration, and extend the service life of the lamp.

[0029] In some preferred embodiments, after the LED flexible light strip is installed into the LED wick installation cavity, the two side surfaces of the lamp bead distribution surface of the LED flexible light strip are fixed by the left side portion of the cavity and the right side portion of the cavity. It should be noted that in this embodiment, the two side surfaces of the lamp bead distribution surface of the LED flexible light strip are fixed by the left side portion and the right side portion of the cavity, which helps to ensure that the flexible light strip maintains a predetermined direction and position in the wick installation cavity. After fixation, the lamp bead distribution surface can always face the corresponding inner wall of the wick shell, realizing a stable and uniform light emission path, making the light distribution of the lamp more uniform.

[0030] In some preferred embodiments, the light-emitting surface of the LED wick is a single light-emitting surface or a double light-emitting surface; when the light-emitting surface of the LED wick is a single light-emitting surface, the single light-emitting surface faces the inner wall of the upper part of the cavity or the inner wall of the lower part of the cavity; when the LED wick has a double light-emitting surface, one of the double light-emitting surfaces faces the upper part of the cavity, and the other of the double light-emitting surfaces faces the lower part of the cavity. It should be noted that in this embodiment, the light-emitting surface of the LED wick is a single or double light-emitting surface, and it faces the upper or lower inner wall of the cavity, which can further refine the adaptability to different light-emitting requirements. Some application scenarios require a single-sided light-emitting wick to meet the lighting needs. At this time, it is only necessary to face its light-emitting surface in a certain direction (up or down); but if it is necessary to obtain higher illumination or uniform illumination in a larger range in the vertical direction, a double light-emitting surface can be selected, and the two surfaces are respectively facing the upper part of the cavity and the lower part of the cavity. Through the cooperation of the transparent wick shell and the outer translucent lamp body shell, the double light-emitting surfaces can scatter and refract within a larger angle range, making the light more evenly distributed in the space around the lamp body, adapting to a variety of lighting occasions and lamp shapes, and further improving the lighting quality of the lamp.

[0031] In some preferred embodiments, the LED wick with double light-emitting surfaces adopts a LED flexible light strip with double light-emitting surfaces, or the LED wick with double light-emitting surfaces adopts two LED flexible light strips with single light-emitting surfaces arranged back to back. It should be noted that in this embodiment, the LED wick with double light-emitting surfaces can adopt a LED flexible light strip with double light-emitting surfaces, or adopt two single-sided LED flexible light strips arranged back to back. The realization of double light-emitting surfaces by these two methods is convenient for flexible selection under the condition of diversified component supply chain: if there is a special double-sided light-emitting flexible light strip, it can directly meet the upper and lower double-sided light-emitting requirements at one time; if it is difficult to obtain a double-sided light strip, two single-sided light strips can be assembled back to back to achieve the same effect, thereby realizing double light-emitting surfaces. In either case, it can be combined with the cavity structure of the aforementioned transparent wick shell, so that the light can be fully scattered and refracted in the upper and lower directions, and the uniformity of omnidirectional light emission is enhanced, thereby greatly improving the feasibility and flexibility of mass production.

[0032] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
