Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lamp. Background Technology

[0002] Currently, for some linear (strip or strip) lighting fixtures, the light source is an LED light strip. Multiple LEDs are arranged in sequence on the LED light strip, which is located on the light-incident surface of the light guide. After the LEDs are lit, the light-emitting surface of the light guide emits light uniformly, resulting in a poor three-dimensional effect of the emitted light, i.e., a poor decorative effect.

[0003] Furthermore, there is a certain spacing between adjacent LEDs. For example, in a multi-color LED light strip, the spacing between two LEDs of the same color is relatively large. When the same color is lit, the lighting effect will appear as follows: Figure 1 The grainy effect in the image refers to the bright spots of the LED particles indicated by the arrows in Figure 1. There is a wide transition area between the bright spots of two LED particles, which is dark, resulting in poor lighting and decorative effects. Utility Model Content

[0004] This utility model provides a lamp to solve the problems of poor decorative effect and grainy lighting effect of existing lamps.

[0005] This utility model provides a lamp, including: a light strip and a light guide. Multiple light sources are arranged on the light strip. The light strip is located on the light-incident surface of the light guide. Multiple parallel prism structures are provided on the light-emitting side of the lamp, and the arrangement direction is consistent with the arrangement direction of the light sources. The width of each prism structure in the arrangement direction is smaller than the distance between two adjacent light sources on the light strip.

[0006] According to the present invention, the width of each prism structure in the arrangement direction is 50% to 60% of the distance between two adjacent light sources on the light strip.

[0007] According to the present invention, a prism structure is disposed on the light-emitting surface of the light guide.

[0008] According to the present invention, a lamp includes at least one light-emitting side, the surface of the light guide opposite to the light-incident surface is a first light-emitting surface, the side where the first light-emitting surface is located is a first light-emitting side, and the first light-emitting surface is provided with the prism structure.

[0009] According to the present invention, a lamp is provided, which further includes a reflector. The lamp includes two light-emitting sides. A microstructure is provided on any side of the light guide perpendicular to the light-incident surface. The reflector is arranged parallel to one side of the light-emitting side. The surface opposite to the light-incident side is a second light-emitting surface. The side where the second light-emitting surface is located is the second light-emitting side of the lamp. The second light-emitting surface is provided with the prism structure.

[0010] According to the present invention, a lamp is provided on the light-emitting side of the lamp, the transparent lamp cover is located on the light-emitting surface of the light guide, and the transparent lamp cover is provided with the prism structure and / or the light-emitting surface of the light guide is provided with the prism structure.

[0011] According to the present invention, a lampshade includes a first transparent plate, a second transparent plate, and a third transparent plate. The first transparent plate and the second transparent plate are parallel and opposite to each other, and both are perpendicular to the third transparent plate. The two ends of the third transparent plate are connected to the first transparent plate and the second transparent plate to form a receiving cavity. The light guide is located in the receiving cavity. The first transparent plate, the second transparent plate, and the third transparent plate are each the light-emitting side of the lamp. A first side of the light guide perpendicular to the light-incident surface is opposite to the first transparent plate. A second side of the light guide opposite to the first side is opposite to the second transparent plate. A light-emitting surface of the light guide opposite to the light-incident surface is opposite to the third transparent plate. At least one of the first side and the second side of the light guide is provided with a microstructure.

[0012] According to the present invention, the first transparent plate, the second transparent plate, and the light-emitting surface of the light guide, which are opposite to the light-incident surface, are all provided with the prism structure.

[0013] According to the present invention, a prism structure on the transparent lampshade is disposed on the surface of the transparent lampshade facing the light guide.

[0014] According to the present invention, the cross-section of the prism structure is circular or triangular.

[0015] The lamp provided by this utility model features multiple prism structures arranged in the direction of the light source on its light-emitting side. Each prism structure has a light-focusing effect, causing the light emitted by the light source to converge at each prism structure, thus forming an alternating bright and dark stripe lighting effect. Compared with traditional lighting effects, this provides a transparent and three-dimensional light emission effect, resulting in a better decorative effect for the lamp. Furthermore, the width of the prism structure in the arrangement direction is smaller than the distance between two adjacent light sources on the light strip. This means that the width of one prism structure will not span two or more light sources, and the light emitted by each light source can converge at at least two prism structures, avoiding a grainy lighting effect caused by light from a single light source converging at only one or a few prism structures.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The lamps of this utility model embodiment, such as Figures 2-5 As shown, it includes: a light strip 1 and a light guide 2, wherein multiple light sources 3 are arranged on the light strip 1. Figure 2 and 3 Only one light source 3 is shown in the diagram, which can be an LED light source. The light strip 1 is located on the light-incident surface side of the light guide 2, that is, the light source 3 is located on the light-incident surface side of the light guide 2. The light-emitting side of the lamp is provided with multiple parallel prism structures 4, and the arrangement direction is consistent with the arrangement direction of the light source 3, such as... Figure 4 As shown, the width W of each prism structure 4 in the arrangement direction is less than the spacing between two adjacent light sources 3 on the light strip 1. The shape of the light strip 1 varies depending on the shape of the luminaire; if it is a ring-shaped luminaire, the light strip 1 is ring-shaped; if it is a straight or curved luminaire, the light strip 1 is a straight or curved light strip. Figure 5 As shown, the light sources 3 on the light strip 1 can be of the same color or different colors arranged in a certain pattern.

[0035] The light-emitting side of the lamp may have one or more. Figure 2 and 3 The illustration shows a luminaire with one light-emitting side. In this case, the light-emitting side of the luminaire is the side where the light-emitting surface of the light guide 2 (usually the surface opposite the incident light surface) is located. Figure 2 and 3 As can be seen, because the light-emitting side of the lamp has multiple prism structures 4 arranged in the same direction as the light source 3, each prism structure 4 has a light-focusing effect. The light emitted by the light source 3 converges at each prism structure 4, thus forming an alternating light and dark stripe lighting effect. Compared with the traditional lighting effect, it has a transparent three-dimensional light emission effect, making the lamp more decorative. Moreover, the width of the prism structure 4 in the arrangement direction is smaller than the distance between two adjacent light sources 3 on the light strip 1. That is, the width of one prism structure 4 will not cross two or more light sources 3. The light emitted by each light source 3 can converge at least two or more prism structures 4, avoiding the grainy lighting effect caused by the light emitted by one light source 3 converging only at one or fewer prism structures 4.

[0036] In some embodiments, the width of each prism structure 4 in the arrangement direction is 50% to 60% of the distance between two adjacent light sources 3 on the light strip 1. In lighting experiments, it was found that if the width of the prism structure 4 is too small, the spacing between the bright and dark stripes is too small, and the visually distinct three-dimensional lighting effect of alternating light and dark is not obvious. Therefore, the width W of the prism structure 4 in the arrangement direction is set to 50% to 60% of the distance between two adjacent light sources 3, ensuring that a grainy lighting effect is avoided while achieving a better visually distinct three-dimensional lighting effect of alternating light and dark.

[0037] In some embodiments, the prism structure 4 is disposed on the light-emitting surface of the light guide 2. Since the light guide 2 itself has a light-emitting surface, in a lamp structure with only one light-emitting side, the side where the light-emitting surface of the light guide 2 is located is the light-emitting side of the lamp. Furthermore, by disposing the prism structure 4 on the light-emitting surface of the light guide 2, the lamp structure is simple, achieving a three-dimensional lighting effect with alternating light and dark areas and avoiding a grainy lighting effect, while also reducing manufacturing costs.

[0038] In some embodiments, such as Figures 6-8 As shown, the luminaire includes at least one light-emitting side. The surface of the light guide 2 opposite to the light-incident surface is the first light-emitting surface, and the side containing the first light-emitting surface is the first light-emitting side. The first light-emitting surface is provided with a prism structure 4. For example, the luminaire may have only one light-emitting side, such as... Figure 7 In the middle, the light-incident surface of the light guide 2 is opposite to the light source 3, that is... Figure 7 The upper surface of the light guide 2 is the light incident surface, and the lower surface is the first light emitting surface. The prism structure 4 is disposed on the lower surface of the light guide 2.

[0039] Furthermore, the luminaire may include two light-emitting sides, and also includes a reflector 5. A microstructure is provided on any side S of the light guide 2 perpendicular to the light-incident surface. The surface opposite to any side S is a second light-emitting surface, and the side containing the second light-emitting surface is the second light-emitting side of the luminaire. The second light-emitting surface is provided with the prism structure 4. The microstructure on any side S can change the original propagation path of the light, allowing the light to exit from any side S and its opposite surface, thus forming a second light-emitting surface on the opposite surface of any side S, achieving two-sided light emission of the luminaire and presenting different decorative effects. The microstructure can be sandblasted, laser-etched (concave), or printed with dots (convex). The reflector 5 is arranged parallel to one side of any side S, and the reflector 5 can be reflective paper or other reflective materials. Specifically, such as... Figure 8 As shown, the light from the light source 3 is emitted from any side S and then reflected again by the reflector 5 into the light guide 2, and emitted from the opposite side of any side S, which reduces the loss of light and increases the brightness of the light emitted from the side.

[0040] Of course, for a lamp with two light-emitting sides, it also includes: a first housing 6 and a second housing 7, the first housing 6 and the second housing 7 being connected by screws 8 to form as shown in the figure. Figure 7 The illustrated assembly structure has an internal cavity, with openings on its bottom and one side for light emission. The LED strip 1, light guide 2, and reflector 5 can all be fixed inside the cavity. In this embodiment, the lamp assembly structure is not limited to... Figure 7 The assembly structure shown can also be other assembly structures that can emit light from both sides.

[0041] like Figure 9 and 10 As shown, for Figure 7 The lighting effect of the lamps in the experiment. Figure 9 From Figure 7 Light emanating from the side (from) Figure 7 The lighting effect observed visually from the lower right side (viewed from the middle right). Figure 10 From Figure 7 The lighting effect observed from the bottom surface shows that whether the light comes out from the side or the bottom, it can achieve a three-dimensional lighting effect with alternating light and dark, and avoids a grainy lighting effect.

[0042] In some embodiments, the light-emitting side of the lamp is provided with a transparent lampshade, which is located on the light-emitting surface of the light guide. The transparent lampshade is provided with the prism structure and / or the light-emitting surface of the light guide is provided with the prism structure.

[0043] For example, such as Figure 7 As shown, if the light fixture only emits light from the bottom, a transparent lampshade can be used to cover the bottom of the fixture. Figure 7In this case, the transparent lampshade can be placed below the light guide 2. If the light fixture emits light from the bottom and one side, the transparent lampshade can cover the bottom and the light-emitting side of the light fixture. Figure 7 In the middle, the transparent lampshade can be placed below and to the right of the light guide 2.

[0044] In this embodiment, a transparent lampshade is provided to prevent dust and water damage. The transparent lampshade can also be designed with a prism structure, allowing for a more flexible design structure for the lamp.

[0045] In some embodiments, such as Figures 11-14 As shown, the lamp includes three light-emitting sides. The transparent lampshade 9 includes a first transparent plate 91, a second transparent plate 92, and a third transparent plate 93. The first transparent plate 91 and the second transparent plate 92 are parallel and opposite to each other, and both are perpendicular to the third transparent plate 93. The two ends of the third transparent plate 93 are connected to the first transparent plate 91 and the second transparent plate 92 to form a receiving cavity. The light guide 2 is located inside the receiving cavity. Figure 12 As shown, the cross-sectional shape of the transparent lampshade 9 is concave. The first transparent plate 91, the second transparent plate 92, and the third transparent plate 93 are each located on a light-emitting side of the lamp. The first side S1 of the light guide 2, perpendicular to the light-incident surface, is positioned opposite to the first transparent plate 91. The second side S2 of the light guide 2, opposite to the first side S1, is positioned opposite to the second transparent plate 92. The light-emitting surface of the light guide 2, opposite to the light-incident surface, is positioned opposite to the third transparent plate 93. At least one of the first side S1 and the second side S2 of the light guide 2 has a microstructure.

[0046] In this embodiment, at least one of the first side S1 and the second side S2 is provided with a microstructure, so that both the first side S1 and the second side S2 can emit light, thereby realizing three-sided light emission of the lamp.

[0047] Of course, for a three-sided light fixture, it also includes: a housing 10, which is connected to a concave transparent lampshade 9 to form a shape such as... Figure 12 The assembly structure shown allows light to emerge from both its bottom and sides. Both the LED strip 1 and the light guide 2 can be fixed inside this assembly structure. In this embodiment, the lighting assembly structure is not limited to... Figure 12 The assembly structure shown can also be other assembly structures that can emit light from three sides.

[0048] In some embodiments, the first transparent plate 91, the second transparent plate 92, and the light-emitting surface of the light guide 2 opposite to the light-incident surface are all provided with the prism structure 4.

[0049] Specifically, such as Figures 12-14As shown, the microstructure on the first side S1 and / or the second side S2 is a dotted network formed by sandblasting. Preferably, both the first side S1 and the second side S2 are sandblasted. The sandblasted network results in a denser dotted network, leading to higher light output on both the first side S1 and the second side S2. Especially when both the first side S1 and the second side S2 are sandblasted, the light output on both sides is higher, ensuring... Figure 12 To improve the brightness of the light emitted from the side of the luminaire, prism structures 4 are provided on the first transparent plate 91 and the second transparent plate 92. Furthermore, for linear luminaires, the thickness d of the light guide 2 is relatively narrow, such as... Figure 4 As shown, the prism structure 4 can be obtained by directly cutting the light guide 2 using a CO2 laser machine. Since the distance between the first transparent plate 91 and the second transparent plate 92 is small, and the width of the third transparent plate 93 is narrow, it is easier to fabricate the prism structure 4 on the first and second transparent plates 91 than on the third transparent plate 93. Therefore, the lamp structure of this embodiment ensures the brightness of light emitted from each of the three sides of the lamp while reducing the complexity of the manufacturing process and saving manufacturing costs.

[0050] In some embodiments, the prism structure 4 on the transparent lampshade 9 is disposed on the surface of the transparent lampshade 9 facing the light guide 2.

[0051] Specifically, such as Figures 12-14 As shown, the prism structure 4 is set on the surface of the light guide 2, which is the first transparent plate 91 and the second transparent plate 92 respectively, i.e., set on the inner wall of the receiving cavity. This ensures that the outer wall of the transparent lampshade 9 is flat, which is convenient for cleaning and maintenance of the lamp.

[0052] In some embodiments, the cross-section of the prism structure 4 is arc-shaped (e.g., semi-circular) or triangular, and any shape that has a converging optical effect is acceptable, preferably a convex lens structure.

[0053] It should be noted that in the above embodiments, the lamp can be strip-shaped or ring-shaped. In particular, for ring-shaped lamps, a certain gap can be tolerated at the hot bending and forming end joint of the light guide 2. The three-dimensional lighting effect of the lamp with alternating light and dark can effectively cover the dark lines caused by the gap at the hot bending and forming end joint of the light guide 2. This can simplify the processing technology of the gap at the hot bending and forming end joint of the light guide 2, making the manufacturing of ring-shaped lamps simpler and cheaper.
