Description

Technical Field

[0001] The present invention belongs to the technical field of lighting equipment, and in particular relates to a lamp body structure and a panel lamp. Background Art

[0002] Panel lights are lighting devices that are installed on suspended ceilings or ceilings in an embedded or ceiling-mounted manner. The light source module of the panel light is set on the side wall or bottom, and the light is irradiated to the outside in a direct-down manner. With the increasing number of application scenarios of panel lights in lighting environments, the uniformity of light on the light-emitting surface has gradually become a key quality point for user experience, thus placing higher requirements on the uniformity of light output of panel lights.

[0003] Due to the limitation of the outer frame, the existing surface light source lamps on the market cause the light around the light-emitting surface to be absorbed by the side walls and become dark, forming an obvious dark band. This is particularly serious when the panel light uses a black frame as the light frame. When splicing is required, the dark band will greatly reduce the experience of the light environment.

[0004] The prior art discloses a direct-down panel light, including a bottom frame, a PCB board and a diffuser plate. The bottom frame includes a bottom plate and side walls, and the side walls surround the edge of the bottom plate to form a trumpet-shaped opening; the PCB board is fixedly arranged on the bottom plate; an LED array can be distributed on the PCB board; the diffuser plate covers the opening end of the trumpet-shaped opening through a top frame, and the light emitted by the LED array can pass through the diffuser plate to emit the panel light. A reflective film is arranged on the surface of the side of the LED array away from the diffuser plate; the bottom plate and the side wall surface can be coated with a reflective film layer or sprayed with reflective paint. The direct-down panel light uses a reflective film layer coating method and a stepped structure to reflect light, and its reflective structure has multiple levels, and it is inevitable that there is still light absorption.

[0053] Example 1

[0054] refer to Figure 1-Figure 5The present embodiment provides a lamp body structure 100 for use in a flat lamp or a panel lamp. The lamp body structure 100 includes a frame 1, a light source assembly 2, and an optical assembly 3. The frame 1 is used as the main body of the lamp frame of the lamp body structure 100 and is used to install the light source assembly 2 and the optical assembly 3. The light emitted by the light source assembly 2 is emitted to the outside after being light-controlled by the optical assembly 3. The frame 1 of the present embodiment is a rectangular structure, preferably a square structure. In some embodiments, the shape of the frame 1 may also be a triangle, a circle, an ellipse, a regular pentagon, a regular hexagon, or other polygonal structures.

[0055] In some embodiments, the frame 1 is an integrally formed structure, such as one-piece stamping. In some embodiments, the frame 1 is a split structure, and the frame 1 includes a plurality of frames 11 connected together. The frame 11 is an aluminum profile member, which has the characteristics of high structural strength and light weight. The frame 11 can be provided with a plurality of slots according to the requirements of component installation and weight reduction.

[0056] In some embodiments, the frames 11 can be fixed together by seamless welding, riveting, screwing, splicing or bonding. In other embodiments, angle brackets can be used at the corners to fix the vertical and adjacent frames 11 together. The frame 1 of this embodiment is composed of four frames 11 of aluminum profiles connected seamlessly together.

[0057] In some embodiments, the frame 1 includes a frame 11 and a back plate 110, and the frame 1 is provided with a chamber 12 on the inner side. The chamber 12 is formed by a plurality of frames 11 and a back plate 110, and the chamber 12 can be used as an installation chamber and a light mixing chamber at the same time. The light source assembly 2 is installed at the bottom of the chamber 12, and emits light during operation. Part of the light is reflected and mixed with the light that has not been reflected in the chamber 12, and then irradiated to the outside from the opening of the chamber 12, that is, the light emitting end of the frame 1.

[0058] The frame 11 includes a first mounting portion 111 of a side panel, a second mounting portion 112, a side panel 113 and a base 114. The side panel 113 is located at the periphery of the lamp body structure 100. The base 114 and the first mounting portion 111 are extended from the side panel 113 toward the chamber 12. The second mounting portion 112 is located between the base 114 and the first mounting portion 111.

[0059] refer to Figure 3The side plate 113 has a first end 1131 and a second end 1132, and the first end 1131 and the second end 1132 are respectively arranged at the lower end and the upper end of the side plate 113. Among them, the base 114 is formed by extending from the first end 1131 of the side plate 113 toward the chamber 12, and is used to install the light source assembly 2; and the first installation portion 111 is formed by extending from the second end 1132 of the side plate 113 toward the chamber 12. It can be seen that the first end 1131 is the light-emitting end of the lamp body structure 100, and the second end 1132 is the light-emitting end of the lamp body structure 100.

[0060] In this embodiment, the length of the base 114 extending from the first end 1131 is greater than the length of the first mounting portion 111 extending from the second end 1132 .

[0061] The optical assembly 3 includes a reflector 31 and a light emitting member 32. The light emitting member 32 is mounted on the first mounting portion 111, and the reflector 31 is mounted in the second mounting portion 112. The reflector 31 is a reflective paper or a reflective film that can be elastically deformed. After elastic deformation, the reflector 31 has an arc-shaped structure, that is, after the reflector 31 is mounted on the second mounting portion 112, the arc-shaped structure convexly faces the cavity 12, thereby performing (secondary) reflection processing on the light emitted by the light source assembly 2.

[0062] The light source assembly 2 is fixedly mounted on the base 114. After power is turned on, part of the light emitted by the light source assembly 2 is directly emitted to the outside through the light emitting member 32, and the other part is reflected by the reflector 31 and then emitted to the outside through the light emitting member 32. The light reflected by the reflector 31 and the light reflected by the reflector are mixed in the chamber 12 to make the light uniform and soft.

[0063] Furthermore, the back plate 110 is disposed at the bottom of the frame 1 and is fixedly connected to the frame 11 , for example, inserted into a back plate mounting groove of the base.

[0064] The first mounting portion 111 includes a first bottom plate 1111 and a first limiting plate 1112. The first bottom plate 1111 is disposed between the side plate 113 and the first limiting plate 1112, that is, the first limiting plate 1112 is located on the inner side of the side plate 113. The first bottom plate 1111 is connected to the side plate 113 and the first limiting plate 1112 respectively, so that the side plate 113, the first bottom plate 1111 and the first limiting plate 1112 are surrounded together to form a first groove 1113. The first groove 1113 is generally U-shaped.

[0065] The light emitting member 32 is a diffusion plate, and its material can be PC (Polycarbonate), PMMA (polymethyl methacrylate) or PS (Poly Styrene), etc. The light emitting member 32 includes a light emitting body 321 and a first edge 322 , and the first edge 322 is disposed on the periphery of the light emitting body 321 .

[0066] The light emitting body 321 may adopt a frosted structure or be provided with a conical or prism microstructure on the surface to adjust the uniformity of light emission and have an anti-glare effect. The light emitting body 321 of this embodiment is an anti-glare flexible diffusion plate structure. In some embodiments, the light emitting member 32 is a PVC diffusion film, which has the characteristic of sound absorption. While obtaining an anti-glare light emitting effect, it can also absorb the noise of the surrounding environment to obtain a noise reduction effect.

[0067] The first edge 322 can be made of the same material as or different from the light output body 321 , and the first edge 322 is connected to the first groove 1113 .

[0068] The second mounting portion 112 includes a second groove 1121 and a limiting groove 1122. The second groove 1121 is arranged above the base 114, and the limiting groove is arranged inside the first limiting plate 1112. Figure 3 and Figure 4 The limiting groove 1122 and the second groove 1121 are respectively located at the upper and lower mounting parts of the second mounting part 112. One end of the reflector 31 is inserted into the second groove 1121, and the other end is inserted into the limiting groove 1122.

[0069] Furthermore, the second mounting portion 112 also includes a second limiting plate 1123 and a bending member 1124. The second limiting plate 1123 is formed by the first limiting plate 1112 extending downward toward the base 114 at the junction with the first bottom plate 1111, and the second limiting plate 1123 is parallel to the side plate 13. The bending member 1124 is formed by the first limiting plate 1112 first protruding toward the chamber 12 on the inner side and then extending obliquely downward toward the base 114. The bending member 1124 has an arc-shaped bending structure, and the limiting groove 1122 is formed by the bending member 1124 and the second limiting plate 1123. In some embodiments, the bending member 1124, the second limiting plate 1123 and part of the first limiting plate 1112 surround and form the limiting groove 1122. The slot size of the limiting groove 1122 is smaller than the slot size of the second groove 1121. When installing the reflector 31 on the second installation portion 112 of the frame 11 , first insert the lower end of the reflector 31 into the second groove 11221 , then bend the reflector 31 into an arc shape and insert the upper end into the limiting groove 1122 .

[0070] Further references Figure 3 , the light source assembly 2 includes a substrate 21 and LED lamp beads 22, and the LED lamp beads 22 are fixed on the substrate 21. In this embodiment, the LED lamp beads 22 are fixed on the substrate 21 by SMD patch welding, and the LED lamp beads 22 are evenly distributed on the substrate 21, ensuring the uniformity of light emission. The substrate 21 is fixedly mounted on the base 114; further, the substrate 21 and the back plate 110 are fixedly connected together, specifically by fasteners 5, such as screws, to lock the substrate 21 and the back plate 110. In some embodiments, a buffer pad 115 is also provided between the substrate 21 and the back plate 110. In other embodiments, the light source assembly 2 is directly fixedly mounted on the base 11, and the substrate 21 is supported on the back plate 110.

[0071] It should be noted that the evenly distributed LED lamp beads 22 form a light-emitting surface 23 after emitting light. The light-emitting surface 23 is a plane, which is located below the second groove 1121 and has a normal line M.

[0072] Combined with reference Figure 2-Figure 5 , with the direction parallel to the normal M as the first direction L1. Along the first direction L1, the height of the reflector 31 before being installed in the second mounting portion 112 is H, that is, the original height of the reflector 31 is H. The distance between the bottom end of the second groove 1121 and the top end of the limiting groove 1122 is D1, and the original height of the reflector 31 is H and has a relationship with the distance D1: H>D1. It can be understood that the original height of the reflector 31 before being installed in the second mounting portion 112 is H; after being installed in the second groove 1121 and the limiting groove 1122 of the second mounting portion 112, the reflector 31 is bent in an arc and convex toward the chamber 12. At this time, the arc length of the arc where the reflector 31 is located is H, and the radius R is greater than 125mm. After the arc bending, the height of the reflector 31 is equal to the distance D1.

[0073] The reflector 31 can be a reflective film or reflective paper structure with a reflectivity of more than 97%. Combined with the design of the reflector 31 convexly protruding toward the chamber 12, the light can be reflected once and twice. During the secondary reflection, the reflector 31 on the opposite side reflects the light back, so that the light emitting element (flexible light emitting film) near the side panel can obtain sufficient brightness.

[0074] Along the first direction L1, the distance between the light emitting surface 32 and the second end 1132 (light emitting end) of the side plate 113 is D2, where D2 is the height of the chamber 12, ie, the light mixing cavity, and the value range of D2 is 70-75 mm, preferably 73 mm.

[0075] The second direction L2 is perpendicular to the normal M and also perpendicular to the first direction L1. Along the second direction L2, the distance between the outer wall of the side panel 113 and the adjacent LED lamp bead 22 is D3, and the value range of D is 23-25mm, preferably 24mm. The spacing of the LED lamp beads 22 adopts a 30*50 rectangular array for light source layout, combined with the light control coordination of the reflector and the light emitting member (flexible light emitting film), so that the lamp body structure obtains a light uniformity of more than 92%.

[0076] Furthermore, along the second direction L2, the distance between the outer wall of the side plate 113 and the inner wall of the first limiting plate 1112 is D4. It can be understood that D4 is the width of the second end 1132 (light emitting end), which ranges from 5.5-6.5 mm, preferably 6 mm. That is, the thickness of the frame can be 6 mm, realizing a truly narrow frame. The frame with a thickness of 6 mm only retains the first groove structure of the light emitting part (light emitting soft film) at the light emitting end, so that the presentation rate of the light emitting surface reaches 97.02%.

[0077] The second groove 1121 is surrounded by the third limiting plate 1125 and the fourth limiting plate 1126 on opposite sides and the second bottom plate 1127. The third limiting plate 1125 is located inside the fourth limiting plate 1126, and the height of the third limiting plate 1125 is less than that of the fourth limiting plate 1126.

[0078] Along the second direction L2, the distance between the outer wall of the side plate 113 and the inner wall of the third limiting plate 1125 is D5, and D5 is 11 mm in width. With this dimension setting, the proportion of the chamber 12 (light mixing chamber) reaches 94.57%, so that the light can be fully mixed in the chamber 12, avoiding the side plate of the frame from forming a projection on the light output member.

[0079] The lamp body structure provided in this embodiment has a reflective member arranged in the second mounting portion of the side panel, and an arc-shaped convex portion is provided toward the light mixing chamber, which reduces the light absorption by the side panel and cooperates with the light emitting member to control the light emitted by the light source assembly to make the light output uniform; moreover, the frame of the lamp body structure adopts a narrow frame, and the light mixing chamber and the light emitting member are both large in size to avoid the situation where the side of the frame is dark, and the optical uniformity reaches more than 92%.

[0080] Example 2

[0081] exist Figure 1-Figure 5 Based on reference Figure 6 In the lamp body structure 100 of the present embodiment, the optical component 3 further includes a light mixing element 33. The light mixing element 33 is a transparent element that can separate the chamber 12 into a first light mixing cavity 121 and a second light mixing cavity 122 that are not connected to each other.

[0082] The light emitted by the light source assembly 2 passes through the first light mixing cavity 121 and the second light mixing cavity 122 and then is emitted to the outside from the light emitting member 32 . At this time, the reflector 31 only reflects the light of the second light mixing cavity 122 .

[0083] Since the light mixing element 33 separates the first light mixing cavity 121 from the second light mixing cavity 122 , foreign objects such as dust, mosquitoes, etc. that enter the first light mixing cavity 121 from the substrate 21 will be blocked outside the second light mixing cavity 122 to avoid affecting the light mixing effect of the second light mixing cavity 122 .

[0084] Foreign objects such as dust and mosquitoes are blocked outside the second light mixing cavity 122, which also avoids the situation where shadows appear on the light emitting surface of the lamp body mechanism 100 due to the presence of foreign objects, further ensuring the uniformity of light emission.

[0085] The light mixing element 33 includes a light mixing body 331 and a second edge 332, which is disposed at the periphery of the light mixing body 331. The second edge 332 is connected to the second groove 1121, and the second edge 332 is connected to the lower end of the reflector 31 to clamp the reflector 31 in the second groove 1121.

[0086] The double-layer structure formed by the light mixing element 33 and the light emitting element 32 can achieve a double absorption effect on the sound around the lamp body 100, thereby achieving the effect of reducing noise and echo.

[0087] Example 3

[0088] exist Figure 1-Figure 6 Based on the reference Figure 7 This embodiment provides a panel lamp 300 , including a sealing member 200 and the lamp body structure 100 of the first or second embodiment.

[0089] In the panel light 300 , a plurality of frames 11 are fixedly connected together by seamless splicing or welding to form a frame 1 . The back plate 110 is disposed at the bottom of the frame 1 , and the light source assembly 2 is fixed on the back plate 110 .

[0090] On the first mounting portion 111 of the frame 11, a sawtooth structure 1114 is provided on the side wall of the first groove 1113. The seal 200 is a silicone pad or a rubber pad, and a tooth structure is provided corresponding to the sawtooth structure 1114. In some embodiments, the seal 200 can be made into an integral structure with the light emitting member 32, that is, the seal 200 and the first edge 322 are integrally formed. Since the light emitting body 321 is a flexible soft film structure, the seal 200 at the first edge 322 can be well installed in the first groove 113. The seal 200 is embedded and connected to the first groove 1113 to achieve the sealing and waterproof function of the panel light on the face.

[0091] The panel light provided in this embodiment adopts a lamp body structure that does not have uneven brightness in the middle of the light-emitting surface at the side panel position close to the frame, making the light-emitting surface more uniform and soft. When multiple panel lights are spliced ​​into a lighting system, the line contour will not be interrupted on the light-emitting surface, ensuring the light output quality.

[0092] The above contents are merely examples and illustrations of the structure of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these obvious replacement forms all belong to the protection scope of the present invention.
