[0019] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0020] Please see Figure 1 and Figure 2This application provides a double-sided light-emitting lamp 100, including a lamp post 10, a lampshade 20, a light source 30, and a light guide 40. The lamp post 10 has a first mounting cavity 11, and a side opening 12 and a light-emitting groove 13 communicating with the first mounting cavity 11; the lampshade 20 is disposed at the side opening 12 of the lamp post 10, and is partially located within the first mounting cavity 11; the light source 30 is disposed on the lampshade 20, and the light emitted by the light source 30 can partially penetrate the lampshade 20, and can be reflected and / or refracted by the lampshade 20; the light guide 40 is disposed on the side of the lampshade 20 near the light-emitting groove 13, and is located within the first mounting cavity 11. The light guide 40 has a protrusion 41, which is inserted into the light-emitting groove 13. The light guide 40 receives the light reflected and / or refracted by the lampshade 20 and emits the light from the protrusion 41.
[0021] With the above configuration, part of the light emitted by the light source 30 of the double-sided light-emitting lamp 100 can penetrate the lampshade 20 and emit light on one side of the lamp post 10. Part of the light is reflected and / or refracted by the lampshade 20 and received by the light guide 40. After multiple reflections and / or refractions inside the light guide 40, it is emitted from the protrusion 41 and emits light on the other side of the lamp post 10. Thus, with the combined action of the lampshade 20 and the light guide 40, the double-sided light-emitting lamp 100 of this application can achieve double-sided light emission using only one light source 30. The structure is simple, the assembly is convenient, the manufacturing cost is low, and it is conducive to mass production. In addition, the light emitted from both sides of the double-sided light-emitting lamp 100 of this application originates from the same light source 30. Therefore, the light on both sides has a synchronous effect. Especially when setting a flowing light effect, the light effect on the back can be kept completely consistent with the light effect on the front, increasing the aesthetics and recognizability of the double-sided light-emitting lamp 100.
[0022] In some embodiments, please refer to Figure 2 and Figure 3 The lampshade 20 includes a base 21 and a diffuser 22 connected to each other. The base 21 is located inside the first mounting cavity 11, and the diffuser 22 is located outside the first mounting cavity 11. The base 21 is provided with a second mounting cavity 211, which is located between the diffuser 22 and the light-emitting groove 13. The light source 30 is disposed in the second mounting cavity 211 and emits light towards the diffuser 22. The base 21 has a light-acting part 212 between the second mounting cavity 211 and the diffuser 22. The light-acting part 212 is configured to transmit part of the light and refract and reflect part of the light.
[0023] Specifically, the light source 30 is disposed in the second mounting cavity 211, the lamp cover 20 has a protective function for the light source 30, and the light-acting part 212 between the light source 30 and the diffuser 22 of the lamp cover 20 can partially transmit, partially refract and reflect the light emitted by the light source 30, and the light-acting part 212 can change the propagation path of the light.
[0024] In some embodiments, the base 21 includes a colorless and transparent material. The transparent portion is used to reduce light loss during reflection and propagation within the lampshade 20 material. The diffuser 22 includes a milky white translucent material. The milky white translucent portion is used to allow different colors of light emitted by the light source 30 to be mixed and homogenized inside the lampshade 20 before being diffused into space, thus achieving a softer light spot effect with higher quality light spots.
[0025] In some embodiments, the base 21 and the diffuser 22 both comprise a flexible material. The lampshade 20 is integrally formed from the flexible material through a two-color co-molding extrusion process, thereby enhancing the connection strength between the two. The flexible material can be silicone, soft acrylic, or other materials.
[0026] In some embodiments, please refer to Figure 1 and Figure 2 The light source 30 includes a lamp board 31 and multiple LED beads 32. The lamp board 31 has a driving circuit internally, and the multiple LED beads 32 are electrically connected to the same side surface of the lamp board 31. The lamp board 31 is fixed to the base 21 of the lampshade 20. The LED beads 32 are either monochrome or multicolor. As an example, the light source 30 in this application uses 5050 packaged RGBCW five-in-one LED beads 32, and all the light-emitting surfaces of the LED beads 32 face the same direction. In some embodiments, the lamp board 31 can be processed together with the lampshade 20 during extrusion processing and placed in the second mounting cavity 211; alternatively, it can be inserted into the second mounting cavity 211 of the lampshade 20 during subsequent lamp assembly.
[0027] In some embodiments, please refer to Figure 2 and Figure 3 The light guide 40 includes a semi-circular arc portion 42, which has opposing concave surfaces 421 and convex surfaces 422. The concave surface 421 abuts against the base 21, and the convex surface 422 abuts against the lamp post 10. A protrusion 41 is disposed on the convex surface 422. The light guide 40 is configured to receive and collect light refracted and reflected by the base 21, allowing light to be emitted from the protrusion 41. The concave surface 421 of the light guide 40 abuts against the base 21 of the lamp cover 20, which can reduce the loss of light propagation. The protrusion 41 and the diffuser 22 are arranged opposite each other in the radial direction, so that light can be emitted from both sides of the lamp post 10.
[0028] It is understood that the light-emitting groove 13 extends axially, and the protrusion 41 extends axially; the number of light-emitting grooves 13 is one or more, and the multiple light-emitting grooves 13 are arranged at circumferential intervals on the lamp post 10; the number of protrusions 41 is the same as the number of light-emitting grooves 13, and one protrusion 41 is correspondingly inserted into one light-emitting groove 13. By setting multiple protrusions 41 to emit light, the aesthetics of the double-sided light fixture 100 can be further enhanced.
[0029] In some embodiments, please refer to Figure 2 The lamp post 10 is provided with a first snap-fit portion 14, and the lamp cover 20 is provided with a second snap-fit portion 213. The first snap-fit portion 14 and the second snap-fit portion 213 are engaged to fix the lamp cover 20 to the lamp post 10. As an example, the first snap-fit portion 14 is located near the side opening 12, and the base 21 of the lamp cover 20 is provided with the second snap-fit portion 213. The first snap-fit portion 14 and the second snap-fit portion 213 are fastened together to reduce the probability of the lamp post 10 and the lamp cover 20 separating radially.
[0030] In some embodiments, the lamp post 10 and the light guide 40 can be fixed by any connection method such as adhesive, snap-fit, fastening, or magnetic attraction. For example, please refer to [reference needed]. Figure 4 The lamp post 10 is provided with a first fixing part 15, and the light guide 40 is provided with a second fixing part 423. The first fixing part 15 and the second fixing part 423 are connected to each other to fix the light guide 40 to the lamp post 10. Further, the first fixing part 15 is a screw hole, the second fixing part 423 is a through hole, and the double-sided light-emitting lamp 100 also includes a fastener. The fastener passes through the through hole and is screwed into the screw hole to fix the light guide 40 to the inner wall of the lamp post 10.
[0031] In some embodiments, to facilitate packaging and transportation of the double-sided light fixture 100, the lampshade 20 is made of a soft material, and the lamp post 10 is assembled in segments. Please refer to... Figure 4 Along the axial direction of the lamp post 10, the lamp post 10 has a first end 16 and a second end 17. At the first end 16, a light guide 40 protrudes from the lamp post 10; at the second end 17, the lamp post 10 protrudes from the light guide 40. Since the light guide 40 protrudes from the lamp post 10, when two double-sided luminaires 100 are spliced together, the same light guide 40 can simultaneously connect the lamp posts 10 of both luminaires, increasing the stability and convenience of the connection. This allows multiple double-sided luminaires 100 to be spliced together axially to form a longer luminaire.
[0032] Please see Figure 5This application also provides an embodiment of a lighting device 1000, which includes at least two of the aforementioned double-sided light-emitting lamps 100, and the at least two double-sided light-emitting lamps 100 can be spliced together axially. For the specific structure and function of the double-sided light-emitting lamps 100, please refer to the above embodiments, which will not be repeated here.
