TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of lighting lamps, in particular to a full-enclosed small-hole light-emitting structure and a downlight. BACKGROUND
[0002] The downlight adopts a spotlight design, which is used to highlight the details of an object and enhance the visual effect. The downlight has a small irradiation range. The downlight is provided with a swing angle structure to enable the downlight to irradiate different positions, thereby improving the application scenarios of the downlight.
[0003] When the downlight swings, the intersection of the light path of the downlight is offset and increased with the swing of the swing angle, thereby causing light efficiency loss. When the light-emitting passage of the downlight is large, the scattered light at the edge of the light-emitting passage is uneven and is prone to cause light leakage.
[0004] A downlight disclosed in comparative document CN202323460639.1 includes a heat sink, a COB light source, a COB support, an optical lens, a front ring, and a shading cup connected into one body to form a lamp body. The lamp body is detachable from the face ring, and the lamp body can also rotate relative to the face ring. The annular seat of the shading cup and the elastic member are detachable. The shading cup is sleeved with the front ring, and the hinged frame plate is embedded in the limiting groove, thereby simplifying the structure and facilitating assembly. However, this scheme cannot solve the problem of offset and increase with the swing of the swing angle, thereby causing light efficiency loss and the scattered light at the edge of the light-emitting passage being uneven and being prone to cause light leakage.

[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0028] like Figures 1 to 4 As shown, this is a fully enclosed pinhole light-emitting structure 10 according to an embodiment of the present disclosure, including a lamp body assembly 100, a lampshade assembly 200, and a light-emitting component 300. The lampshade assembly 200 includes a rotating shell 210 and a reflector 220. The rotating shell 210 is sleeved on one end of the lamp body assembly 100 and rotatably connected to the lamp body assembly 100. A mounting groove 2101 is formed inside the rotating shell 210. The light-emitting component 300 is connected to the lamp body assembly 100 and located within the mounting groove 2101. The reflector 220 is connected to the rotating shell 210 away from the lamp body assembly 100. At one end, the reflector 220 covers the mounting groove 2101. The reflector 220 has a raised conical surface 221 at one end adjacent to the rotating shell 210. The raised conical surface 221 has a light-emitting hole 2201. The light-emitting hole 2201 is used to limit the emitted light from the light-emitting component 300. The rotating shell 210 limits the rotation of the lamp assembly 100 so that the focal point of the light-emitting component 300 is located at the light-emitting hole 2201 and the internal space of the rotating shell 210 corresponding to the light-emitting hole 2201. The corresponding internal space is the space between the light-emitting hole 2201 in the vertical direction and the rotating shell 210.
[0029] In this embodiment, light is emitted from the light-emitting component 300. After passing through the mounting groove 2101, the light is emitted through the light-emitting hole 2201. The central area of the mounting groove 2101 contains denser direct light, and the direct light from the light-emitting component 300 converges to a focal point. The edge area of the mounting groove 2101 contains less light and more scattered light at a larger angle. When the reflector 220 is placed over the mounting groove 2101, it blocks the scattered light from the edge of the mounting groove 2101. By rotating the housing 210 to limit the rotation of the lamp body assembly 100, the focal point of the oscillating light-emitting component 300 is in the light-emitting hole 2201 and the internal space of the rotating housing 210 corresponding to the light-emitting hole 2201. This allows the light to converge at the focal point of the light-emitting component 300 and then smoothly pass through the light-emitting hole 2201 for emission.
[0030] When the full-enclosing small-hole light-emitting structure 10 is covered by the reflector 220, the reflector 220 blocks the scattered light at the edge of the mounting groove 2101, and the more concentrated direct light passes through the light-emitting small hole 2201, thereby reducing the problem of light leakage caused by the scattered light. The rotation of the rotating shell 210 limits the rotation of the lamp body assembly 100, so that the focal point of the swing light-emitting assembly 300 is in the light-emitting small hole 2201 and the internal space corresponding to the light-emitting small hole 2201 of the rotating shell 210. The light converges at the focal point of the light-emitting assembly 300, so that the light passes through the light-emitting small hole 2201 smoothly, reduces the loss of light efficiency, and makes the light irradiation effect better.
[0031] In one of the examples, the reflector 220 is provided with a clamping block 222, and the side of the rotating shell 210 away from the lamp body assembly 100 is provided with a clamping opening 2101, and the clamping block 222 is clamped in the clamping opening 2101. In this embodiment, the reflector 220 is clamped with the rotating shell 210 through the clamping block 222, so that the reflector 220 and the rotating shell 210 are convenient to disassemble and assemble, and the connection between the reflector 220 and the rotating shell 210 is more compact.
[0032] As shown in the figure, Figure 1 In one of the examples, the rotating shell 210 includes a rotating shell body 211 and an extension shell 212, the rotating shell body 211 is rotationally connected with the lamp body assembly 100, and the extension shell 212 is connected to one end of the rotating shell body 211 away from the lamp body assembly 100. In this embodiment, the extension shell 212 increases the accommodation space of the mounting groove 2101, so that the rotating shell body 211 can accommodate more components, thereby improving the flexibility and functionality of the whole device.
[0033] Figure 1 As shown in the figure, In one of the examples, the light-emitting assembly 300 includes a light-emitting source 310, a light-emitting lens 320, and a lens gland 330. The lamp body assembly 100 is provided with a light source mounting groove 101, the light-emitting source 310 is mounted in the light source mounting groove 101, one end of the light-emitting lens 320 abuts against the light-emitting source 310, the lens gland 330 is sleeved on the light-emitting lens 320 and abuts against the other end of the light-emitting lens 320, and the lens gland 330 is connected to the lamp body assembly 100. In this embodiment, the light-emitting lens 320 abuts against the light-emitting source 310, so that the light emitted by the light-emitting source 310 is adjusted in the direction of emission by the light-emitting lens 320, and more light is emitted forward, thereby reducing the scattering loss of the light-emitting source 310. The lens gland 330 is sleeved on the light-emitting lens 320, so that the emitted light is in the space of the lens gland 330, thereby reducing the problem of light leakage.
[0034] Figure 1As shown in the drawings, in one of the examples, the light-emitting lens 320 includes a first light-transmitting part 321 and a second light-transmitting part 322, the first light-transmitting part 321 and the second light-transmitting part 322 are connected integrally, and the radius of the second light-transmitting part 322 is greater than that of the first light-transmitting part 321. In this embodiment, the light rays enter the second light-transmitting part 322 from the first light-transmitting part 321 in turn, and when the lens gland 330 abuts against the outer edge of the second light-transmitting part 322, the radius of the second light-transmitting part 322 is greater than that of the first light-transmitting part 321, thereby reducing the blocking of the lens gland 330 to the light rays, and reducing the light loss of the emitted light rays.
[0035] As shown in the drawings, Figure 1 In one of the examples, the lens gland 330 includes a cylindrical part 331 and a conical cylindrical part 332, the cylindrical part 331 is sleeved on the light-emitting lens 320, the cylindrical part 331 is connected to the lamp body assembly 100, and the conical cylindrical part 332 is connected to one end of the cylindrical part 331 away from the light-emitting source 310. In this embodiment, the light-emitting lens 320 is fixed by the cylindrical part 331, so that the light-emitting path of the light rays is fixed, and the conical cylindrical part 332 can reflect the light rays scattered from the light-emitting lens 320, so that the light rays converge and are emitted through the light-emitting small hole 2201, thereby reducing the light loss of the emitted light rays.
[0036] As shown in the drawings, Figure 1 In one of the examples, the light-emitting small hole 2201 is located in the passage of the conical cylindrical part 332. In this embodiment, after the light rays pass through the light-emitting lens 320, they all enter the conical cylindrical part 332, the light rays in the center of the conical cylindrical part 332 are more concentrated, the light rays outside the outer edge of the center of the conical cylindrical part 332 are less, and the light-emitting small hole 2201 is located in the conical cylindrical part 332, so that the light rays in the center of the conical cylindrical part 332 pass through the light-emitting small hole 2201 and are emitted, thereby making the direct effect of the emitted light rays better, and the distance between the reflector 220 and the conical cylindrical part 332 is shorter, so that the structure of the reflector 220 and the conical cylindrical part 332 is more compact.
[0037] As shown in the drawings, Figure 1 In one of the examples, the convex conical surface 221 is a circular arc surface structure. In this embodiment, the convex conical surface 221 of the reflector 220 is a circular arc surface structure, so that the stress concentration in the structure is reduced, the overall stability of the structure is improved, and the convex conical surface 221 can converge light rays in different directions, thereby improving the utilization efficiency of the light rays.
[0038] As shown in the drawings, Figure 1As shown, in one of the instances, the light reflecting cover 220 is provided with a light source mounting groove 101 adjacent to one side of the light emitting assembly 300, and the rotating shell 210 is adapted to be embedded in the light source mounting groove 101 at the end away from the lamp body assembly 100. In this embodiment, the end of the rotating shell 210 away from the lamp body assembly 100 is adapted to the light source mounting groove 101, so that the assembly of the light reflecting cover 220 and the rotating shell 210 is more compact, thereby improving the connection strength of the light reflecting cover 220 and the rotating shell 210.
[0039] The application also provides a cylindrical spotlight comprising the full-enclosed small-hole light emitting structure 10 in any of the above embodiments. In this embodiment, the control of the emergent light rays by the full-enclosed small-hole light emitting structure 10 makes the focal point of the light emitting assembly 300 located in the light emitting small hole 2201 and the internal space corresponding to the light emitting small hole 2201 of the rotating shell 210, thereby reducing the problems of light efficiency loss and light leakage.
[0040] Compared with the prior art, the present disclosure has at least the following advantages:
[0041] The full-enclosed small-hole light emitting structure 10 and the cylindrical spotlight described above, when the light reflecting cover 220 is covered on the mounting container groove 2101, the light reflecting cover 220 blocks the scattered light rays at the edge of the mounting container groove 2101, and the more concentrated direct light rays pass through the light emitting small hole 2201 to emit light, thereby reducing the problem of light leakage caused by scattered light rays. The rotating shell 210 limits the rotation of the lamp body assembly 100, so that the focal point of the light emitting assembly 300 after swinging is located in the light emitting small hole 2201 and the internal space corresponding to the light emitting small hole 2201 of the rotating shell 210, and the light rays converge at the focal point of the light emitting assembly 300, so that the light rays pass through the light emitting small hole 2201 to emit light smoothly, reducing the light efficiency loss of the light rays, and making the light rays have a better irradiation effect.
[0042] The above-described embodiments only express several embodiments of the present disclosure, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the disclosed patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which are within the scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
