[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0028] like Figures 1 to 5 As shown, the lighting assembly of an embodiment of the present invention includes a lamp housing 1, a white light source 2, a light guide 3 and a filter 4. The lamp housing 1 has a receiving cavity with a transmission window, the white light source 2 is located in the receiving cavity, and the filter 4 is arranged in the receiving cavity and located between the white light source 2 and the transmission window. The filter 4 is used to convert the light passing through the filter 4 into blue-green light.
[0029] Optionally, the lighting assembly further includes a light guide 3 , which is connected to the white light source 2 to transmit the light emitted by the white light source 2 to the outside along a preset path, and the filter 4 is arranged on the preset path.
[0030] Specifically, if Figure 1 As shown, one end of the lamp housing 1 facing the outside has an opening, and an accommodating space is formed inside the lamp housing 1. The light source, the light guide 3 and the filter 4 are all located in the accommodating space.
[0031] The light source is a white LED that emits white light. One end of a light guide 3 is connected to the white light source 2, allowing it to transmit the light generated by the white light source 2 to the outside world. In terms of light propagation, the light guide 3 is located downstream of the white light source 2, and the optical filter 4 is also located downstream of the light source. In other words, light emitted by the light source can first pass through the optical filter 4, then enter the light guide 3, and then be transmitted to the outside world. Alternatively, light emitted by the light source can first pass through the light guide 3, then enter the optical filter 4, and then be transmitted to the outside world. Alternatively, light emitted by the light source can first pass through the light guide 3, then pass through the optical filter 4, and then pass through the remaining portion of the light guide 3 before being transmitted to the outside world.
[0032] It should be noted that the white light passing through the filter 4 can be changed into blue-green light. For example, a blue-green dye is sprayed on the filter 4 so that the white light is changed into blue-green when passing through the filter 4.
[0033] The lighting assembly of the embodiment of the present invention utilizes the existing white light source 2 that can generate white light and is additionally equipped with a filter 4 to achieve the effect of blue-green light. Compared with the blue-green LED white light source 2 that can generate blue-green light, the manufacturing cost of the lighting assembly can be reduced. In addition, the filter 4 and the white light source 2 are two independent components, which facilitates subsequent maintenance and reduces subsequent maintenance costs.
[0034] In some embodiments, the optical filter 4 includes a body 41 and a dye layer 42 . The dye layer 42 is coated on the outer surface of the body 41 , or the dye layer 42 is located inside the body 41 .
[0035] Specifically, if Figures 1 to 4 As shown, the coloring layer 42 can be sprayed on the outer wall surface of the sheet body 41, or the coloring layer 42 can be pasted on the outer wall surface of the sheet body 41, or the coloring layer 42 can be integrally formed with the sheet body 41 by injection molding.
[0036] It should be noted that the dye layer 42 and the sheet body 41 can be integrally formed or detachably connected. The sheet body 41 is provided to facilitate the connection between the filter 4 and the light guide 3.
[0037] For example, the dyeing layer 42 may be located inside the sheet 41 , for example, the dyeing layer 42 and the sheet 41 may be integrally injection molded. Alternatively, the sheet 41 may be divided into two pieces, with the dyeing layer 42 sandwiched between the two pieces.
[0038] In some embodiments, the dye layer 42 is coated on the outer surface of the sheet 41 . The dye layer 42 is located on a side of the sheet 41 adjacent to the white light source 2 , or the dye layer 42 is located on a side of the sheet 41 away from the white light source 2 .
[0039] It should be noted that when the dyeing layer 42 is covered on the outer surface of the sheet 41, the dyeing layer 42 can be located on the inner side of the sheet 41. When the dyeing layer 42 is located on the inner side of the sheet 41, the dyeing layer 42 cannot be observed from the outside. Alternatively, the dyeing layer 42 can be located on the outer side of the sheet 41. When the dyeing layer 42 is located on the outer side of the sheet 41, the dyeing layer 42 is visible from the outside, thereby meeting the diversity of the appearance of the lighting component.
[0040] In some embodiments, the lighting assembly also includes a light blocking bracket 5 and a frame 6, and the frame 6 and the light blocking bracket 5 are both installed in the lamp housing 1. The light blocking bracket 5 is connected to the light guide 3, and the light blocking bracket 5 and the frame 6 surround the periphery of the light guide 3, and the frame 6 is arranged relative to the light blocking bracket 5 away from the white light source 2.
[0041] Specifically, if Figures 1 to 4As shown, the light blocking bracket 5 is connected to the light guide 3, the light blocking bracket 5 and the frame 6 are located on the periphery of the light guide 3, and the frame 6 is located on the right side of the light blocking bracket 5. In other words, the frame 6 is arranged closer to the outside world relative to the light blocking bracket 5. The light blocking bracket 5 and the frame 6 can prevent the light from the light guide 3 from overflowing, improve the effect of light propagation, and thereby improve the light quality of the lighting assembly.
[0042] In some embodiments, the filter 4 is connected to the light guide 3, and the filter 4 is located inside the light guide 3, the filter 4 is arranged adjacent to the white light source 2, or, the filter 4 is located outside the light guide 3, and the end face of the filter 4 away from the white light source 2 is flush with the end face of the frame 6 away from the white light source 2.
[0043] Specifically, if Figure 1 and Figure 2 As shown, the filter 4 can be pasted on the light guide 3, or the filter 4 and the light guide 3 are integrally injection molded, the filter 4 is located inside the light guide 3, and the filter 4 is located in the middle and upper reaches of the light guide 3. In other words, the filter 4 is located in the middle position of the light guide 3 or in the middle position close to the white light source 2.
[0044] Alternatively, the filter 4 is located outside the light guide 3, that is, the filter 4 is installed on the side of the light guide 3 close to the outside world, and the end face of the filter 4 close to the outside world is flush with the end face of the frame 6 close to the outside world, which ensures the appearance of the lighting component and prevents the light guide 3 from protruding from the frame 6 to cause light overflow and affect the quality of light transmission.
[0045] In some embodiments, the light guide 3 includes a first light guide portion 31 and a second light guide portion 32 that are detachably connected. The first light guide portion 31 is arranged adjacent to the white light source 2 relative to the second light guide portion 32 , and the filter 4 is located between the first light guide portion 31 and the second light guide portion 32 .
[0046] Specifically, if Figure 3 As shown, the light guide 3 is divided into a first light guide part 31 and a second light guide part 32 that are detachably connected. The first light guide part 31 is connected to the white light source 2. In the direction of light propagation, the second light guide part 32 is located downstream of the first light guide part 31. The filter 4 is located between the first light guide part 31 and the second light guide part 32. The filter 4 is installed between the detachably connected first light guide part 31 and the second light guide part 32, so that the filter 4 becomes an independent component, which not only facilitates the processing and manufacturing of the filter 4, but also allows for separate maintenance when the lighting component is damaged, thereby reducing the maintenance cost of the lighting component in the later stage.
[0047] For example, the first light guide portion 31 and the second light guide portion 32 may be detachably connected by snapping or bonding.
[0048] In some embodiments, the optical filter 4 is connected to the frame 6 , and an end surface of the optical filter 4 away from the white light source 2 is flush with an end surface of the frame 6 away from the white light source 2 .
[0049] Specifically, if Figure 4 As shown, the filter 4 is connected to the frame 6. In the direction of light propagation, the filter 4 is located downstream of the light guide 3, that is, after the light is emitted by the white light source 2, it first passes through the light guide 3 and then passes through the filter 4, and finally propagates to the outside.
[0050] It should be noted that the inner side of the filter 4 can be in contact with the light guide 3, or the inner side of the filter 4 can be spaced apart from the light guide 3. The end surface of the filter 4 facing the outside is flush with the end surface of the frame 6 facing the outside, ensuring the appearance of the lighting assembly is not affected and preventing the light guide 3 from protruding from the frame 6, causing light to overflow and affecting the light transmission quality.
[0051] In some embodiments, the lighting assembly further includes a lampshade 7 , which is connected to the lamp housing 1 to seal the interior space of the lamp housing 1 .
[0052] It should be noted that the lampshade 7 includes two parts, one is a black lampshade 7, and the other is a transparent lampshade 7. The transparent lampshade 7 is facing the light guide 3, and the inner side of the transparent lampshade 7 is a black lampshade 7. By arranging the black lampshade 7, not only can the diversity of the appearance of the lighting component be enriched, but also the light can be prevented from being too divergent, thereby ensuring the effect of light propagation.
[0053] In some embodiments, the white light source 2 includes a light board 21 and a plurality of light groups 22 . The plurality of light groups 22 are respectively connected to the light board 21 , and the plurality of light groups 22 are spaced apart and distributed on the light board 21 .
[0054] Specifically, if Figures 1 to 4 As shown, the light board 21 is connected to the light guide 3, and a plurality of light groups 22 are provided on the light board 21. By providing a plurality of light groups 22, the brightness of light can be increased and the light quality of the light assembly can be improved.
