The adjustment component 32 is used to control the size of the light outlet 11, so as to facilitate the adjustment of the lighting range and help control the diffusion of light, thereby helping to reduce direct glare and improve visual comfort.

[0038] Reference Figure 2 and Figure 3 The anti-glare panel group 31 includes a honeycomb panel 311 and a light diffusion panel 312. The honeycomb panel 311 and the light diffusion panel 312 are respectively installed in the lamp housing 1.

[0039] Reference Figure 3 and Figure 4A plurality of connection holes 3111 are provided on the honeycomb panel 311. One connection hole 3111 corresponds to one lamp bead 22, and an anti-glare net 3112 is fixedly connected to each connection hole 3111. The anti-glare net 3112 can split the light so that one beam of light is split into multiple beams of light to reduce the brightness of each beam of light.

[0040] Reference Figure 3 and Figure 5 A plurality of diffusion holes 3121 are formed through the light diffusion plate 312, and a diffusion hole 3121 is correspondingly arranged with a connection hole 3111, and a light guide tube 3122 is fixedly connected in each diffusion hole 3121, and the light guide tube 3122 contacts the honeycomb plate 311 and is connected with the connection hole 3111, so that the light can be incident into the light guide tube 3122 after passing through the connection hole 3111, so that the light can be refracted by the light guide tube 3122, which is conducive to reducing the generation of glare.

[0041] Reference Figure 2 The adjustment assembly 32 includes a fixed ring 321, a rotating ring 322 and a plurality of adjusting members 323. The rotating ring 322 is integrally formed with a connecting ring 324. The lamp housing 1 is provided with a ring groove 12. The connecting ring 324 is slidably inserted into the ring groove 12 and fits with the inner wall of the ring groove 12, so that the connecting ring 324 can limit the rotating ring 322, so that the rotating ring 322 is not easy to be separated from the lamp housing 1, and the rotating ring 322 can rotate on the lamp housing 1.

[0042] In this embodiment, a sealing ring 13 is filled between the connecting ring 324 and the inner wall of the annular groove 12 , which improves the sealing performance between the rotating ring 322 and the lamp housing 1 on the one hand, and helps to improve the stability of the connecting ring 324 inserted in the annular groove 12 on the other hand.

[0043] Reference Figure 3 , the rotating ring 322 is arranged near the light outlet 11, the fixed ring 321 is installed in the lamp housing 1 and arranged near the light diffuser 312, and the rotating ring 322 and the fixed ring 321 are arranged at intervals. Multiple adjustment members 323 are slidably arranged between the rotating ring 322 and the fixed ring 321, and the multiple adjustment members 323 are evenly distributed around the axial direction of the fixed ring 321, and each adjustment member 323 is slidably connected to the rotating ring 322 and the fixed ring 321. In this embodiment, adjacent adjustment members 323 slide against each other, and multiple adjustment members 323 cooperate with each other to block the light outlet 11.

[0044] Each adjusting member 323 is provided with a through hole 3231 and a first guide groove 3232 , a plurality of first protrusions 3221 are fixedly connected to the rotating ring 322 , a plurality of second protrusions 3211 are fixedly connected to the fixing ring 321 , and a plurality of second guide grooves 3212 are provided on the fixing ring 321 around its own axis.

[0045] One end of the first protrusion 3221 passes through the through hole 3231 and is slidably inserted into the second guide groove 3212, and the second protrusion 3211 is slidably inserted into the first guide groove 3232. In this embodiment, the cross-sections of the first protrusion 3221 and the second protrusion 3211 are both circular in design, so that the first protrusion 3221 can slide smoothly in the second guide groove 3212, and the second protrusion 3211 can slide smoothly in the first guide groove 3232.

[0046] Reference Figure 3 When the rotating ring 322 rotates, the rotating ring 322 can drive the first protrusion 3221 to move in the second guide groove 3212, and the first protrusion 3221 applies a force to the adjusting member 323 to drive the adjusting member 323 to move. At this time, the second protrusion 3211 moves in the first guide groove 3232 and applies a force to the inner wall of the first guide groove 3232 to guide the adjusting member 323, thereby facilitating driving the multiple adjusting members 323 to move closer to or away from each other, so as to adjust the positions of the multiple adjusting members 323 relative to the light outlet 11, and then facilitating adjusting the size of the light outlet 11 according to lighting requirements.

[0047] In other embodiments, a handle may be fixedly connected to the side of the rotating ring 322 away from the adjusting member 323 , so that a force can be applied to the rotating ring 322 by using the handle, thereby driving the rotating ring 322 to rotate.

[0048] Reference Figure 2 A light guide 3213 is embedded in the fixing ring 321, so that the fixing ring 321 can block the side of the light guide 3213 close to the fixing ring 321, so that after the light is incident into the light guide 3213, it is not easy to be emitted from the side of the light guide 3213 close to the fixing ring 321, thereby enabling the light to be transmitted along the specified direction as much as possible.

[0049] In other embodiments, the light guide 3213 may also be directly mounted on the fixing ring 321 , and a light-proof layer may be provided on the light guide 3213 , so that light can be conducted as much as possible along a designated direction.

[0050] Reference Figure 2 and Figure 3 A light-transmitting member 14 is embedded in the circumference of the lamp housing 1, and the light-guiding member 3213 is in contact with the light-transmitting member 14. When the light emitted by the lamp bead 22 passes through the light diffusion plate 312, part of the light will be irradiated on the light-guiding member 3213, so that the light-guiding member 3213 transmits the light to the light-transmitting member 14, so that the light passes through the light-transmitting member 14 and irradiates toward the side of the lamp housing 1, thereby facilitating elimination of the side shadow of the lamp housing 1 and improving the lighting effect.

[0051] Reference Figure 2 and Figure 3 The side of the rotating ring 322 away from the adjusting member 323 is fixedly connected with a floodlight 3222, which can make the irradiated light uniform to reduce glare. The floodlight 3222 cooperates with the sealing ring 13 to further improve the sealing performance of the overall structure, so that impurities such as external moisture or dust are not easy to enter the lamp housing 1 through the rotating ring 322, which is conducive to reducing the erosion of impurities on the internal components of the lamp housing 1, and further conducive to extending the service life of the downlight.

[0052] Reference Figure 3 A heat sink 4 is fixedly connected to one end of the lamp housing 1 away from the light outlet 11. The heat sink 4 is connected to the circuit board 21, and the heat sink 4 includes a plurality of heat sinks, so that the heat sink 4 can be used to dissipate heat from the circuit board 21 to reduce the accumulation of heat inside the lamp housing 1, thereby helping to reduce the possibility of damage to the circuit board 21 and the lamp bead 22 due to excessive temperature, thereby increasing the service life of the downlight.

[0053] The implementation principle of the embedded LED downlight in the embodiment of the present application is as follows: when the lamp bead 22 works to emit light, the anti-glare net 3112 will first split a beam of light into multiple beams, and the split light will be incident into the light guide tube 3122, and will be emitted from the light outlet 11 after being refracted by the light guide tube 3122. In this process, part of the light will be incident into the light guide member 3213 after leaving the light guide tube 3122, and will be conducted by the light guide member 3213 to the light transmissive member 14, and finally emitted from the light transmissive member 14, so as to facilitate the realization of the lighting effect.
