Description

At present, the photosensitive initiators contained in light-curing materials of different manufacturers or models may be different, and can be more efficiently cured only by irradiation of light of corresponding wavelength, so in order to adapt to different photosensitive initiators, the light irradiated by the light source of the light-curing machine is usually mixed light composed of two different colors of light.

[0003] The light-curing machines on the market now have some defects: the light emitted by the light source of the current dental light-curing machine is directly emitted through a lens, and the direct light output form of the light source has the advantages of good condensing effect, small divergence angle and strong penetration, but the different color lights output by the light source are not mixed uniformly, which may affect the curing effect of the light-curing material in the local area, and may cause uneven curing, leading to local cracking and the like; in particular, the current dental light-curing light source is arranged in a rectangular shape, and the light spot is not round enough, thereby causing uneven light curing in the edge area and poor light curing effect.

[0054] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0055] This application provides a light-emitting module, such as... Figures 1 to 6 As shown, the light-emitting module includes: a plurality of light-emitting units distributed in a circular light-emitting area 1, the circular light-emitting area 1 including a central area 11, the circular light-emitting area 1 being divided into n linearly arranged partitions, where n is an odd number and equal to or greater than 3; the partitions include a first area 12, a second area 13, and a third area 14 arranged linearly; the central area 11 is centrally located in the second area 13, the light-emitting units are divided into a first light-emitting unit 21 and a second light-emitting unit 22 according to different emission colors; the central area 11 is provided with at least one second light-emitting unit 22, and the remaining areas are provided with a plurality of first light-emitting units 21; or, a plurality of second light-emitting units 22 are arranged around the central area 11, the central area 11 is provided with at least one second light-emitting unit 22 and / or a first light-emitting unit 21, and the remaining areas are provided with a plurality of first light-emitting units 21.

[0056] In the embodiment, the light-emitting units are divided into first light-emitting units 21 and second light-emitting units 22 according to the light-emitting color; the second light-emitting units 22 are arranged in the middle region 11, and the first light-emitting units 21 are arranged in the remaining regions; or the second light-emitting units 22 are arranged around the middle region 11, and the middle region 11 is provided with the first light-emitting units 21 or the second light-emitting units 22, and the remaining regions are provided with the first light-emitting units 21; the second light-emitting units 22 are not placed alone at one angle of the circular light-emitting region 1, or the second light-emitting units 22 are not placed eccentrically in the circular light-emitting region 1, so that the light emitted by the first light-emitting units 21 and the second light-emitting units 22 can be mixed uniformly, and the irradiation light spot can be avoided to have a gap, so that the application of the light-emitting module on the light curing machine can improve the curing uniformity and reduce the local cracking.

[0057] In the embodiment, n is limited to be an odd number greater than 3, so as to ensure that the center of the circular light-emitting region 1 is located at the middle position after the division, thereby avoiding that the second light-emitting units 22 are placed alone at one angle of the circular light-emitting region 1 or the second light-emitting units 22 are placed eccentrically in the circular light-emitting region 1, so that the light emitted by the first light-emitting units 21 and the second light-emitting units 22 can be mixed uniformly.

[0058] Of course, n can also be 5, 7, etc.; no matter n is selected from any odd number, the middle region 11 is located in the middle of the second region 13, and the first region 12 and the third region 14 are located at two ends of the second region 13; when n is 5, the division includes the fourth region (not shown), the first region 12, the second region 13, the third region 14 and the fifth region (not shown) arranged in line; when n is 7, the division includes the sixth region (not shown), the fourth region (not shown), the first region 12, the second region 13, the third region 14, the fifth region (not shown) and the seventh region (not shown) arranged in line; and so on.

[0059] Specifically, the first light-emitting units 21 are blue light-emitting chips, and the second light-emitting units 22 are violet light-emitting chips, so that the light-emitting module realizes the mixing of blue light and violet light, and can provide a wide-spectrum curing effect; because the photosensitive initiator in the photocuring material has a higher curing efficiency under violet light irradiation, the mixing of blue light and violet light can improve the curing effect of the photocuring material, and when the second light-emitting units 22 are lit alone, they can also be used for caries detection.

[0060] In the embodiment, the uniform mixing means that the violet light is uniformly doped in the blue light, and the violet light spot is not irradiated eccentrically, but the size of the non-violet light and the blue light is uniform.

[0061] Furthermore, all the first light-emitting units 21 are electrically connected to each other.

[0062] In this embodiment, all the first light-emitting units 21 are connected in series or in parallel to achieve electrical connection, so as to synchronously control the opening and closing of the first light-emitting units 21.

[0063] Furthermore, all the second light-emitting units 22 are electrically connected to each other.

[0064] In this embodiment, all the second light-emitting units 22 are connected in series or in parallel to achieve electrical connection, so as to synchronously control the opening and closing of the second light-emitting units 22.

[0065] Example One:

[0066] like Figure 1 As shown, further, a first axis of symmetry 3 and a second axis of symmetry 4 are vertically arranged along the radial direction of the circular light-emitting area 1; when the number of the second light-emitting unit 22 is one, the second light-emitting unit 22 is arranged in the middle area 11, and the remaining areas are provided with the first light-emitting unit 21, and all the first light-emitting units 21 are symmetrically arranged along the first axis of symmetry 3 and the second axis of symmetry 4.

[0067] In Embodiment 1, the first axis of symmetry 3 and the second axis of symmetry 4 divide the circular light-emitting area 1 into four equal parts. When the number of second light-emitting units 22 is one and they are located in the middle area 11, the remaining areas are provided with first light-emitting units 21. All first light-emitting units 21 are symmetrically arranged along the first axis of symmetry 3 and the second axis of symmetry 4, which improves the uniformity of each area in the circular light-emitting area 1.

[0068] Furthermore, the area of ​​the second light-emitting unit 22 is larger than the area of ​​the first light-emitting unit 21.

[0069] In Embodiment 1, the area of ​​the second light-emitting unit 22 is larger than the area of ​​the first light-emitting unit 21, so as to improve the illuminance of the second light-emitting unit 22.

[0070] Furthermore, in the first region 12 and the third region 14, the length direction of the first light-emitting unit 21 is consistent with the extension direction of the second axis of symmetry 4; in the second region 13, the extension direction of the first light-emitting unit 21 is consistent with the first axis of symmetry.

[0071] Furthermore, in the first region 12 and the third region 14, m1 first light-emitting units 21 are provided at the end away from the second region 13, and the m1 first light-emitting units 21 are symmetrically arranged along the first axis of symmetry 3, where m1 is an even number; in the first region 12 and the third region 14, m2 first light-emitting units 21 are provided at the end adjacent to the second region 13, and the m2 first light-emitting units 21 are symmetrically arranged along the first axis of symmetry 3, where m2 is an odd number, and the first axis of symmetry 3 coincides with the bisector of the length direction of the first light-emitting unit 21 adjacent to the middle region 11.

[0072] In Example 1, m1 is 2 and m2 is 3.

[0073] Furthermore, in the second region 13, the length direction of the first light-emitting unit 21 is consistent with the extension direction of the first axis of symmetry 3.

[0074] Furthermore, in the second region 13, multiple first light-emitting units 21 are respectively provided on both sides of the second light-emitting unit 22; the second axis of symmetry 4 coincides with the bisector of the length direction of the first light-emitting unit 21.

[0075] like Figures 2 to 6 As shown, further, a third axis of symmetry 5 and a fourth axis of symmetry 6 are vertically arranged along the radial direction of the circular light-emitting area 1; when the number of the second light-emitting units 22 is greater than or equal to two, all the first light-emitting units 21 and all the second light-emitting units 22 are symmetrically arranged along the third axis of symmetry 5 and the fourth axis of symmetry 6.

[0076] In this embodiment, the third axis of symmetry 5 and the fourth axis of symmetry 6 divide the circular light-emitting area 1 into four equal parts. When the number of second light-emitting units 22 is greater than or equal to two, all first light-emitting units 21 and all second light-emitting units 22 are arranged along the third axis of symmetry 5 and the fourth axis of symmetry 6, which improves the uniformity of each region in the circular light-emitting area 1.

[0077] Example Two:

[0078] like Figure 2 As shown, further, the number of the second light-emitting units 22 is x, where x is an even number, and the second light-emitting units 22 are located in the middle region 11, while the remaining regions are provided with a plurality of the first light-emitting units 21; wherein, in the second region 13, the length direction of the second light-emitting units 22 is consistent with the length direction of the first light-emitting units 21, and x second light-emitting units 22 are located on both sides of the third axis of symmetry 5.

[0079] In Example 2, x is 2.

[0080] In the second embodiment, when there are two second light-emitting units 22, the length direction of the second light-emitting unit 22 is consistent with the length direction of the first light-emitting unit 21, so that the two second light-emitting units 22 are symmetrically arranged along the third axis of symmetry 5, which improves the light mixing uniformity of the circular light-emitting area 1.

[0081] Furthermore, the area of ​​the second light-emitting unit 22 is larger than the area of ​​the first light-emitting unit 21.

[0082] In the second embodiment, the area of ​​the second light-emitting unit 22 is larger than the area of ​​the first light-emitting unit 21, so as to improve the illuminance of the second light-emitting unit 22.

[0083] Furthermore, in the first region 12 and the third region 14, the length direction of the first light-emitting unit 21 is consistent with the extension direction of the fourth axis of symmetry 6; in the second region 13, the extension direction of the first light-emitting unit 21 is consistent with the extension direction of the third axis of symmetry.

[0084] Furthermore, in the first region 12 and the third region 14, m3 first light-emitting units 21 are provided at the end away from the second region 13, and the m3 first light-emitting units 21 are symmetrically arranged along the third axis of symmetry 5, where m3 is an even number; in the first region 12 and the third region 14, m4 first light-emitting units 21 are provided at the end adjacent to the second region 13, and the m4 first light-emitting units 21 are symmetrically arranged along the third axis of symmetry 5, where m4 is an odd number, and the third axis of symmetry 5 coincides with the bisector of the length direction of the first light-emitting unit 21 adjacent to the middle region 11.

[0085] In Example 2, m3 is 2 and m4 is 3.

[0086] Furthermore, in the second region 13, the length direction of the first light-emitting unit 21 is consistent with the extension direction of the third axis of symmetry 5.

[0087] Furthermore, in the second region 13, two first light-emitting units 21 are respectively provided on both sides of the second light-emitting unit 22; the fourth axis of symmetry 6 coincides with the bisector of the length direction of the first light-emitting unit 21.

[0088] Example Three:

[0089] like Figure 3 As shown, the difference from Embodiment 2 is that in the second region 13, the length direction of the second light-emitting unit 22 is perpendicular to the length direction of the first light-emitting unit 21, and the two second light-emitting units 22 are located on both sides of the fourth axis of symmetry 6.

[0090] In Embodiment 3, when there are two second light-emitting units 22, the length direction of the second light-emitting unit 22 is perpendicular to the length direction of the first light-emitting unit 21, so that the two second light-emitting units 22 are symmetrically arranged along the fourth axis of symmetry 6, which improves the light mixing uniformity of the circular light-emitting area 1.

[0091] Example Four:

[0092] like Figure 4 As shown, further, the number of the second light-emitting units 22 is y1, where y1 is greater than or equal to 5; each of the first region 12 and the third region 14, away from the second region 13, is provided with y2 second light-emitting units 22, where y2 is an even number, and the y2 second light-emitting units 22 are symmetrically arranged along the third axis of symmetry 5; the middle region 11 is provided with one second light-emitting unit 22, the bisector of the length direction of the second light-emitting unit 22 in the middle region 11 coincides with the fourth axis of symmetry 6, and a first light-emitting unit 21 is provided on each side of the second light-emitting unit 22; the remaining regions are provided with a plurality of first light-emitting units 21.

[0093] In Example 4, y1 is 5 and y2 is 2.

[0094] In Embodiment 4, two second light-emitting units 22 are provided at the ends of the first region 12 and the third region 14 away from the second region 13, and a second light-emitting unit 22 is provided in the middle of the two first light-emitting units 21 in the middle region 11.
