Description

Technical Field

[0001] The present invention relates to the field of lighting, and particularly to a lamp shade and a lamp. Background Art

[0002] Currently, the lighting effect of lamps on the market is getting better and better, and the light transmittance, color, and structure of the lamp shade are crucial for the lighting effect of the lamp.

[0003] Now, the application of two-color extrusion lamp shades in lamps is becoming more and more widespread. Through the combination of two different color structures, the light passing through the lamp shade can present a better lighting effect. However, in the existing two-color extrusion lamp shades, the surfaces of different structures are closely attached, so the final presented effect will appear relatively chaotic and not transparent enough.

[0004] In view of this, it is indeed necessary to provide a lamp shade and a lamp that can make the light of the lamp more transparent when passing through the lamp shade and emitting outward. Summary of the Invention

[0005] The purpose of the present invention is to provide a lamp shade that can improve the sense of demarcation.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0029] Here, it should be noted that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the drawings, while other details less related to the present invention are omitted.

[0030] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0031] Please refer to Figures 1-2 As shown, the present invention discloses a lamp shade 100, which includes a diffusion structure 110 and a light - emitting structure 120. Among them, the diffusion structure 110 is directly connected to the lamp 200. The light emitted by the lamp 200 will first enter the diffusion structure 110, and the diffusion structure 110 will diffuse the light;

[0032] The light - emitting structure 120 covers the diffusion structure 110. The light - emitting structure 120 is configured to control the emission angle of the light emitted by the lamp 200. An air cavity 130 is provided between the light - emitting structure 120 and the diffusion structure 110. One end of the air cavity 130 close to the light - emitting structure 120 is configured to reflect the light entering the light - emitting structure 120 from the outside. At the same time, the colors of the light - emitting structure 120 and the diffusion structure 110 are different.

[0033] The air cavity 130 provided between the light-emitting structure 120 and the diffusion structure 110 provides a reflecting surface for the light rays that enter the hollow part of the light-emitting structure 120 from the outside. The light rays that enter the light-emitting structure 120 from the outside can be reflected on the surface of the air cavity 130, making the demarcation and transparency between the diffusion structure 110 and the light-emitting structure 120 of different colors stronger. Furthermore, the light rays emitted outward through the lamp shade 100 present a better light-emitting effect.

[0034] In this embodiment, the color of the diffusion structure 110 is milky white, and the color of the light-emitting structure 120 is transparent. The transparent light-emitting structure 120 is combined with the milky white diffusion structure 110. The light rays emitted by the lamp 200 first pass through the milky white diffusion structure 110, then pass through the air cavity 130 and enter the transparent light-emitting structure 120. The overall light-emitting effect is better, and the light-transmitting property of the transparent light-emitting structure 120 is stronger, achieving a shiny effect.

[0035] In this embodiment, the light-emitting surface 121 of the light-emitting structure 120 and the side surfaces on both sides of the light-emitting surface 121 can emit light outward. From different angles, a good visual effect can be presented.

[0036] In this embodiment, the diffusion structure 110 and the light-emitting structure 120 are integrally formed. The lamp shade 100 is made by using an integral extrusion molding process, and the manufacturing cost is lower. At the same time, compared with an injection-molded lamp shade 100 or other combined lamp shades 100, it has the advantage of no splicing. Therefore, no additional assembly procedure is required and it can be cut into the required length according to the lamp tubes of different length requirements, achieving the effects of low cost and high production efficiency.

[0037] In other embodiments, the diffusion structure 110 and the light-emitting structure 120 can also be two independent structures, and the two structures form the lamp shade 100 through splicing. The present invention does not limit this.

[0038] A light-emitting surface 121 is provided at one end of the light-emitting structure 120 away from the air cavity 130. Microstructures are provided in the light-emitting surface 121. By using the microstructures on the light-emitting surface 121, the light rays will be reflected in the microstructures on the light-emitting surface 121 of the light-emitting structure 120, thereby increasing the angle of the light rays emitted from the light-emitting surface 121 and making the irradiation coverage area of the lamp shade 100 wider.

[0039] One end of the light-emitting structure 120 close to the diffusion structure 110 has a first end face 113, and one end of the diffusion structure 110 close to the light-emitting structure 120 has a second end face 122. In this embodiment, both the first end face 113 and the second end face 122 are arc surfaces protruding away from the diffusion structure 110. The first end face 113 and the second end face 122 form the air cavity 130. As Figure 5As shown, the light emitted by the lamp 200 enters the air cavity 130 through the first end face 113, and then exits the air cavity 130 from the second end face 122. The structure is simple. The external light enters through the light-emitting surface 121 of the light-emitting structure 120, is reflected by the second end face 122, and then exits outward through the light-emitting surface 121 to enhance the demarcation between the two structures of different colors, namely the light-emitting structure 120 and the diffusion structure 110.

[0040] In some other embodiments, the cross-section of the second end face 122 may also be in a broken line shape, and the present invention does not limit this.

[0041] In this embodiment, the proportion of the area where the tangent on the second end face 122 forms an angle R with the horizontal plane in the range of 0° to 45° on the second end face 122 is less than 50%, so as to ensure that the area of the region on the second end face 122 that can reflect external light is large enough and the reflected light is sufficient to improve the visual effect.

[0042] One end of the diffusion structure 110 facing away from the light-emitting structure 120 is provided with a receiving cavity 112. The receiving cavity 112 is configured to receive the light emitted by the lamp 200. An extension portion 114 extends outward from the side wall of the receiving cavity 112, and the extension portion 114 abuts against the lamp 200. When assembling with the lamp 200, the receiving cavity 112 will snap into the lamp slot 210 of the lamp 200 and cover the light-emitting component 220 of the lamp 200. The light-emitting component 220 emits light toward the receiving cavity 112, and an extension portion 114 extends outward from the side wall of the receiving cavity 112, and the extension portion 114 abuts against one end of the lamp slot 210 of the lamp 200.

[0043] In this embodiment, the maximum thickness H3 of the air cavity 130 is 4 mm, the maximum height H1 of the receiving cavity in the diffusion structure 110 is 9 mm, and the maximum thickness H2 between the top of the receiving cavity 112 and the first end face 113 is 3 mm. That is, the maximum height of the diffusion structure 110 is H1 + H2 = 12 mm. When the thickness of the above structure is the above value, the light emitted by the light-emitting component 220 can be maximally emitted outward through the light-emitting surface 121 of the light-emitting structure 120. In other embodiments, the thickness or height of each of the above structures may also be other values, and the present invention does not limit this.

[0044] In this embodiment, the distance between the light-emitting units in the light-emitting component 220 is D, and the maximum thickness of the receiving cavity 112 in the diffusion structure 110 is H1. Then H1 / D > 1.2. When H1 / D satisfies the above relationship, the light emitted by each light-emitting unit can be better mixed in the diffusion structure 110, making the light emitted outward from the light-emitting surface 121 more uniform and eliminating the granularity.

[0045] In this embodiment, a clamping portion 111 is provided at one end of the accommodation cavity 112 away from the diffusion structure 110. The accommodation cavity 112 is clamped to the lamp 200 through the clamping portion 111. This connection structure is simple and the assembly is convenient and fast.

[0046] In this embodiment, the diffusion structure 110 and the light-emitting structure 120 are made of PMMA material or PC material. Among them, the PMMA material is easy to process and is suitable for the extrusion processing technology. At the same time, it has a high light transmittance and a relatively light weight. In some other embodiments, other light-transmitting materials can also be used according to actual needs. The present invention does not limit this.

[0047] As Figure 4 shown, the lamp 200 in a preferred embodiment of the present invention includes the above-mentioned lamp cover 100 and a lamp slot 210. As Figure 3 shown, a light-emitting component 220 is installed in the lamp slot 210. The lamp slot 210 includes a slot bottom 211 and a slot wall 212. The light-emitting component 220 is installed in the slot bottom 211 of the lamp slot 210. A connecting portion 2121 extends inward from the slot wall 212 of the lamp slot 210. In this embodiment, the connecting portions 2121 on the slot walls 212 on both sides of the lamp slot 210 are arranged at intervals and staggered. The clamping portions 111 in the accommodation cavity 112 of the lamp cover 100 are also arranged at intervals and staggered. In this way, when connecting the lamp cover 100 to the lamp slot 210 of the lamp 200, only need to insert the accommodation cavity 112 of the lamp cover 100 into the lamp slot 210 and then rotate it to make the connecting portion 2121 coincide with the clamping portion 111, then the assembly of the lamp slot 210 and the lamp cover 100 can be completed, which is convenient and fast, and at the same time, the disassembly and installation are relatively convenient.

[0048] In summary, the lamp cover 100 of the present invention includes a diffusion structure 110, a light-emitting structure 120, and an air cavity 130 provided between the diffusion structure 110 and the light-emitting structure 120. The diffusion structure 110 and the light-emitting structure 120 have different colors. External light is incident on one end of the air cavity 130 connected to the light-emitting structure 120 after passing through the light-emitting structure 120, and is reflected and then emitted outward through the light-emitting structure 120, so that the demarcation between the diffusion structure 110 and the light-emitting structure 120 of different colors is stronger, and the lamp cover 100 presents a better light-emitting effect.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
