[0028] In order to solve the problem of poor light uniformity in the light ring device in the prior art, the utility model provides a light ring device and a robot.
[0029] like Figures 1 to 5 As shown, the light ring device includes a shell 10, a light-emitting element 20, a reflector 30 and a light-transmitting ring 50, the shell 10 has a receiving groove; the light-emitting element 20 is annular, and the annular light-emitting element 20 is arranged in the receiving groove; the reflector 30 is arranged in the receiving groove and is located on the light-emitting side of the light-emitting element 20, the reflector 30 at least includes a first reflecting ring 31 and a second reflecting ring 32 arranged concentrically, and at least a part of the light-emitting element 20 is located between the first reflecting ring 31 and the second reflecting ring 32; the light-transmitting ring 50 is covered at the notch of the receiving groove and the light-transmitting ring 50 is arranged corresponding to the light-emitting element 20.
[0030] By providing the receiving groove, the receiving groove provides an installation position for the light emitting element 20 and the reflector 30, which is conducive to ensuring the reliability of the use of the light emitting element 20 and the reflector 30. The reflector 30 at least includes a first reflecting ring 31 and a second reflecting ring 32 arranged concentrically, and at least a part of the light emitting element 20 is located between the first reflecting ring 31 and the second reflecting ring 32. Such an arrangement enables the central light emitted by the light emitting element 20 to be normally emitted by the light-transmitting ring 50, and the edge light emitted by the light emitting element 20 can be emitted by the light-transmitting ring 50 after multiple reflections by the first reflecting ring 31 and the second reflecting ring 32, thereby reducing light loss, increasing light efficiency, and increasing light uniformity, thereby ensuring user experience.
[0031] Specifically, the light emitting element 20 includes a circuit board and a plurality of lamp beads mounted on the circuit board, wherein the plurality of lamp beads are arranged at intervals and form a circle of lamp beads, thereby forming an annular aperture and achieving an annular light emitting effect.
[0032] like Figure 2 and Figure 3 As shown, the first reflection ring 31 and the second reflection ring 32 are both extended in a direction away from the light emitting member 20, so that the first reflection ring 31 and the second reflection ring 32 are arranged opposite to each other, the first reflection ring 31 has a first reflection surface 311 on the side facing the second reflection ring 32, and the second reflection ring 32 has a second reflection surface 321 on the side facing the first reflection ring 31, and both the first reflection surface 311 and the second reflection surface 321 are arc surfaces. By vertically placing the first reflection ring 31 and the second reflection ring 32 on both sides of the light emitting member 20 and setting the first reflection surface 311 and the second reflection surface 321 to be arc surfaces, it is beneficial for the first reflection surface 311 and the second reflection surface 321 to continuously reflect the light of the light emitting member 20, and the uniformity of light emission is increased through reflection, and the brightness uniformity is further ensured.
[0033] Specifically, the light ring device further includes a reflective layer, and the first reflective surface 311 and the second reflective surface 321 are both provided with a reflective layer; by providing the reflective layer, the reflective effect of the first reflective surface 311 and the second reflective surface 321 can be increased, and the uniformity of the emitted light can be further ensured.
[0034] Moreover, a reflective layer is also provided on the inner ring surface of the light-transmitting ring 50, specifically, a reflective layer is provided on the contact surface between the light-transmitting ring 50 and the fixing member 40. Such a setting is conducive to allowing the light entering the light-transmitting ring 50 to be emitted outward, that is, the light entering the light-transmitting ring 50 is emitted from the top surface 51 and the outer ring surface 52 of the light-transmitting ring 50. By providing a reflective layer on the inner ring surface of the light-transmitting ring 50, it is beneficial to reflect the light incident on the inner ring surface, and then emit it from the top surface 51 and the outer ring surface 52, thereby ensuring the light output efficiency, ensuring the brightness, and at the same time ensuring the uniformity of the light output.
[0035] Optionally, the reflective layer is a metal layer.
[0036] like Figure 2 and Figure 3 As shown, the reflector 30 further includes a cover bottom 33, which is annular, and the first reflective ring 31 and the second reflective ring 32 are connected through the cover bottom 33 on the side facing the light-emitting element 20, and the cover bottom 33 is located on the side of the first reflective ring 31 and the second reflective ring 32 away from the light-transmitting ring 50. The first reflective ring 31 and the second reflective ring 32 are equivalent to being respectively arranged on both sides of the cover bottom 33, and the first reflective ring 31 is located on the inner side of the second reflective ring 32. The inner ring diameter of the first reflective ring 31 is smaller than the inner ring diameter of the second reflective ring 32. Preferably, the radial width of the first reflective ring 31 is equal to the radial width of the second reflective ring 32, and the radial width of the first reflective ring 31 can also be set to be smaller than the radial width of the second reflective ring 32.
[0037] Specifically, the cover bottom 33 includes a plurality of through holes 331, and the plurality of through holes 331 are arranged at intervals, and at least a portion of the light-emitting member 20 extends from the through holes 331 to the space between the first reflecting ring 31 and the second reflecting ring 32. The plurality of lamp beads are arranged in a one-to-one correspondence with the plurality of through holes 331, that is, the plurality of lamp beads extend from the side of the reflector 30 away from the light-transmitting ring 50 through the plurality of through holes 331 into the space between the first reflecting ring 31 and the second reflecting ring 32 in a one-to-one correspondence, and such an arrangement enables the through holes 331 to limit the lamp beads, thereby avoiding the risk of the light-emitting member 20 shaking during the operation of the light ring device, and at the same time, achieving stable assembly of the reflector 30 and the light-emitting member 20.
[0038] like Figure 1As shown, the light ring device further includes a fixing member 40, which is disposed in the receiving groove and connected to the housing 10, and at least a portion of the fixing member 40 protrudes from the notch of the receiving groove, and the inner ring surface of the light-transmitting ring 50 has a snap-fit structure 53, and the portion of the fixing member 40 protruding from the receiving groove has a snap-fit member 43, and the snap-fit structure 53 is snap-fitted with the snap-fit member 43. One of the snap-fit structure 53 and the snap-fit member 43 is a snap-fit groove, and the other of the snap-fit structure 53 and the snap-fit member 43 is a snap-fit protrusion. This arrangement enables the assembly of the light ring device to be realized by snap-fitting the fixing member 40 with the light-transmitting ring 50, which is conducive to ensuring the structural stability of the light ring device and increasing the convenience of assembly.
[0039] In a specific embodiment of the present application, the fixing member 40 has a snap-in protrusion, which is continuously arranged around the circumference of the fixing member 40; the transparent ring 50 has a snap-in groove, which is located on the inner ring surface of the transparent ring 50, and the snap-in groove is continuously arranged around the inner ring surface of the transparent ring 50 and connected end to end.
[0040] like Figure 1 As shown, the fixing member 40 includes a first fixing portion 41 and a second fixing portion 42 arranged in sequence, and the first fixing portion 41 is located on a side of the second fixing portion 42 away from the light-transmitting ring 50. The first fixing portion 41 is fixedly connected to the housing 10 by screws, and the second fixing portion 42 is columnar, and the surface of the side of the columnar second fixing portion 42 away from the first fixing portion 41 is a plane; the outer peripheral surface of the columnar second fixing portion 42 has a clamping member 43, specifically a clamping protrusion; the light-emitting member 20 and the reflector 30 are sequentially sleeved on the outer peripheral side of the second fixing portion 42 in a direction away from the first fixing portion 41, and the light-emitting member 20 and the reflector 30 are located between the first fixing portion 41 and the clamping member 43, and the light-transmitting ring 50 is covered at the notch of the receiving groove of the housing 10 and is clamped with the fixing member 40, and the central hollow area of the light-transmitting ring 50 is adapted to the fixing member 40, so that the light-transmitting ring 50 and the fixing member 40 can form a seal with the receiving groove.
[0041] like Figure 4 As shown, Figure 4 The black arrow in the middle indicates the direction of light emission. The light-transmitting ring 50 is in the shape of a cover. The top surface 51 of the cover-shaped light-transmitting ring 50 is a plane, and the outer ring surface 52 is an arc surface. Both the top surface 51 and the outer ring surface 52 of the light-transmitting ring 50 can realize the emission of light. The top surface of the fixing member 40 is flush with the top surface 51 of the light-transmitting ring 50, and the outer ring surface 52 of the light-transmitting ring 50 smoothly transitions with the outer peripheral surface of the shell 10. In a specific embodiment of the present application, the light-transmitting ring 50 is made of PC material with excellent light transmission performance, and a light diffusing agent is mixed in the PC material to scatter the light entering the light-transmitting ring 50, thereby making the emitted light more uniform. Since both the top surface 51 and the outer ring surface 52 of the light-transmitting ring 50 can realize the emission of light, the light can be evenly emitted along the top surface 51 and the outer ring surface 52, and is not easily blocked due to posture problems.
