[0039] like Figure 3 As shown, the present invention provides a reflective light structure, which includes a reflector 1 , a light source 2 and a first substrate 3 .

[0040] The reflector 1 is elongated and has a curved reflective surface 11 and a reflective cavity 12 formed by the curved reflective surface. The curved reflective surface 11 extends along the length of the reflector 1 and has a first reflective focus and a second reflective focus on a plane perpendicular to the length of the reflector 1. The reflector 1 is a reflector, and preferably, the curved reflective surface 11 is an elliptical curved reflective surface to ensure efficient light utilization.

[0041] The light source 2 comprises a plurality of LEDs arranged along the length of the reflector 1. The light source 2 is positioned on one side of the reflective cavity 12 and faces the reflective cavity 12. The light emission center of the light source 2 is located at the first reflective focal point. By positioning the light emission center of the light source at the first reflective focal point of the reflector, the present invention collects a 120° angle of light emitted by each light source through the first reflective focal point, achieving approximately four times the original light efficiency and significantly improving light utilization efficiency.

[0042] See also Figure 4 The first substrate 3 is located on the other side of the reflective cavity 12, and the second reflective focal point is located on the surface of the first substrate 3 near the reflective cavity 12. The first substrate is light-guiding glass. In the present invention, the second reflective focal point of the reflector is located on the light-entering surface of the light-guiding glass, thereby smoothly guiding LED light into the glass and ensuring efficient light utilization.

[0043] Furthermore, the reflective light structure further includes a PCBA board 4, and the light source 2 is mounted on the PCBA board 4. The PCBA board 4 is partially located above the reflective cavity 12. Preferably, the light source 2 faces and extends into the reflective cavity 12 to ensure that the light emitted by the light source can be irradiated onto the curved reflective surface 11 to the greatest extent.

[0044] Please continue reading Figure 3 and Figure 5 , the reflector 1 also includes a first connecting plate 13 and a second connecting plate 14, and the second connecting plate is a mounting plane. The first connecting plate 13 extends outward from one edge of the reflective cavity 12, and the second connecting plate 14 extends outward from the other edge of the reflective cavity 12. The PCBA board 4 is detachably connected to the first connecting plate 13, and the second connecting plate 14 is fixed to the other surface of the first substrate 3. In the present invention, the PCBA board is connected to the first connecting plate by hot riveting. Preferably, the PCBA board is detachably connected to the first connecting plate by snaps, screws and / or rivets, which is conducive to the later maintenance of the product. Preferably, the PCBA board is snapped onto the first connecting plate by snaps. Preferably, the second connecting plate 14 is bonded to the other surface of the first substrate 3 by an adhesive 6. Preferably, the adhesive is 3M glue.

[0045] In one embodiment, a bracket 5 is further included, one side of the bracket 5 is bonded and fixed to the other surface of the first substrate 3, and the other side of the bracket 5 is detachably connected to the second connecting plate 14 by snaps, screws and / or rivets, which is beneficial for the later maintenance of the product.

[0046] Please continue reading Figure 3 and Figure 4 The present invention also provides a reflective light atmosphere lamp, comprising a light shielding member 7, a second substrate 8, and the aforementioned reflective light structure. The light shielding member 7 is a light shielding rubber strip, the second substrate 8 is glass, preferably a car sunroof glass, and the reflective light structure is located on the inner surface of the sunroof glass. The reflective light atmosphere lamp of the present invention is not only suitable for sunroof atmosphere lighting.

[0047] The light shielding member 7 forms a receiving cavity 9, and the second substrate 8 is disposed over the opening of the receiving cavity 9. The light-reflecting structure is located within the receiving cavity 9, and the first substrate 3 abuts against and is fixed to the second substrate 8. Preferably, one surface of the first substrate 3, i.e., the light-emitting surface, is bonded to the light-incident surface of the second substrate 8 using 3M adhesive.

[0048] like Figure 4 As shown, light from light source 2 strikes curved reflective surface 11, which reflects the light. The curved reflective surface 11 then focuses the light onto the side surface of the light-guiding glass at a second reflection focus before entering the light-guiding glass. The light then strikes one surface of the light-guiding glass and is projected from that surface into the skylight glass, where it continuously reflects and propagates through the glass, thereby illuminating the skylight atmosphere light. The skylight glass of the present invention is coated with reflective ink to reflect light, ensuring that more light is reflected to the desired location.

[0049] (1) The reflective light structure and reflective light atmosphere lamp of the present invention can increase the light that can be collected at an angle of 120° from that originally only at a 30° angle by using a reflector, and the light efficiency is about 4 times that of the original one, which greatly improves the efficiency of light utilization.
