[0059] Unless otherwise specified, in the description of the specific embodiments of the present utility model, the expression terms indicating the orientation or position relationship such as "upper", "lower", "left", "right", "center", "inside", "outside", etc. are all based on the expression of the orientation or position relationship shown in the drawings, or the orientation or position relationship when the product / equipment / device of the utility model is usually used. These terms of orientation or position relationship are only for the convenience of describing the scheme of the utility model or simplifying the description in the specific embodiments, so that technicians can quickly understand the scheme, rather than indicating or implying that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific position relationship, and therefore cannot be understood as a limitation on the present utility model.

[0060] In addition, if the terms "horizontal", "vertical", "overhanging", "parallel" and the like appear, it does not mean that the corresponding devices / components / elements are required to be absolutely horizontal or vertical or overhanging or parallel, but may be slightly tilted or have deviations. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but may be slightly tilted. Alternatively, it can be simplified to mean that the corresponding devices / components / elements are set in directions such as "horizontal", "vertical", "overhanging", "parallel", etc., and can have an error / deviation of ±10% relative to the corresponding direction setting, more preferably an error / deviation within ±8%, more preferably an error / deviation within ±6%, more preferably an error / deviation within ±5%, and more preferably an error / deviation within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its role in the solution of the utility model.

[0061] In addition, the expressions “first”, “second”, “third”, etc., which appear in the terms, are merely used to distinguish the description of the same or similar components and should not be understood as emphasizing or implying the relative importance of specific components.

[0062] In addition, in the description of the embodiments of the present invention, "several", "multiple" and "a number" represent at least 2. It can be any number such as 2, 3, 4, 5, 6, 7, 8, 9, and even more than 9.

[0063] In addition, in the description of the technical solution of the utility model, unless otherwise clearly specified / defined / restricted, the terms "set", "install", "connect", "connected", "provided with", "laid", and "arranged" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, and can be welding, riveting, bolting, threading, and other commonly used connection means in the field. This connection can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal communication of two components.

[0064] Example 1

[0065] like Figure 1-7 As shown, an LED optical system with built-in ambient lighting includes a reflective cup 1, a lens 2, and an ambient lighting structure 3.

[0066] The bottom of the reflective cup 1 is provided with a light entrance hole 11 for LED light to enter. After the LED light enters the reflective cup 1 , it is reflected by the wall of the reflective cup 1 and then emitted to the lens 2 .

[0067] The lens 2 is arranged in a one-to-one correspondence with the reflector cup 1, that is, the number of the lens 2 is consistent with that of the reflector cup 1, and the arrangement position is also consistent. The lens 2 is arranged on the light-emitting side of the reflector cup 1, and usually, the lens light-entering surface 21 is arranged close to the light-emitting side of the reflector cup 1. The LED light is reflected by the reflector cup 1 and then enters the lens light-entering surface 21, and is emitted through the first light-emitting surface 22 to form basic lighting.

[0068] The combination of the reflector 1 and the lens 2 can combine the light energy reflected by the reflector 1 with the energy that has not passed through the reflector 1, so that the basic lighting part can obtain uniform light distribution and realize uniform light energy distribution, such as Figure 8-9 shown.

[0069] The atmosphere lighting structure 3 is used to realize atmosphere lighting. The atmosphere lighting structure 3 is connected with the lens 2 as an integral unit, so that it is easy to assemble the basic lighting part and the atmosphere part, and it is convenient to realize various atmosphere lighting.

[0070] The atmosphere lighting structure 3 includes a reflective surface 31, a microstructure surface 32 and a second light emitting surface 33. Part of the LED light overflows from the lens 2 and is reflected by the reflective surface 31 before entering the microstructure surface 32. After being reflected by the microstructure surface 32, it is emitted from the second light emitting surface 33 to achieve atmosphere lighting. Fig.10 shown.

[0071] By providing the microstructure surface 32 , uniform light energy distribution can be further achieved while achieving ambient lighting, thereby improving the uniformity of the ambient lighting light.

[0072] In an optional implementation, the reflector 1 and the lens 2 can be snap-connected. For example, in this embodiment, the reflector 1 is provided with a snap slot 12, and the lens 2 is provided with a snap buckle 23. When the connection is fixed, it is only necessary to insert the snap buckle 23 into the snap slot 12.

[0073] In an optional embodiment, the lens 2 and the atmosphere lighting structure 3 can be an integral injection-molded structural component. Usually, the atmosphere lighting structure 3 can be integrally connected to the lens 2 through the reflective surface 31. That is, the reflective surface 31 is arranged close to the lens 2, and the microstructure surface 32 and the lens 2 are respectively arranged on both sides of the reflective surface 31, so that it is convenient for the LED light to overflow from the lens 2 and then enter the reflective surface 31 for reflection.

[0074] In an optional embodiment, the atmosphere lighting structure 3 can be arranged at the outer edge of the lens 2, so as to facilitate the connection between the atmosphere lighting structure 3 and the lens 2. For example, in this embodiment, the reflector cup and the lens 2 are both arranged separately, and the atmosphere lighting structure 3 is arranged at the outer circumference of the lens 2.

[0075] In an optional embodiment, the microstructure surface 32 may be formed by a plurality of microstructure arrays, and the microstructures may include prisms or pyramids. For example, in this embodiment, the microstructures are prism structures, and are arranged in a circular array along the outer circumference of the lens 2. By changing the specific structural form and arrangement of the microstructures in the microstructure surface 32, a variety of different atmosphere lighting can be formed to meet the lighting requirements of different occasions.

[0076] In an optional implementation, the light incident surface 21 of the lens is provided with a compound eye structure 211, which can further achieve the effect of light uniformity.

[0077] In an optional implementation, the shape of the lens light incident surface 21 is square or circular. In this embodiment, the shape of the lens light incident surface 21 is circular, which is consistent with the shape of the light emitting side of the reflective cup 1, thereby improving the utilization rate of light energy.

[0078] Example 2

[0079] like Figure 11-12 As shown, compared with Example 1, the specific structural form of the atmosphere lighting structure 3 in this embodiment is different from that in Example 1.

[0080] In this embodiment, the microstructures in the microstructure surface 32 of the atmosphere lighting structure 3 are pyramids and are evenly arranged along the microstructure surface 32 .

[0081] Example 3

[0082] like Figure 13-14 As shown, compared with Example 1, the specific structural form of the atmosphere lighting structure 3 in this embodiment is different from that in Example 1.

[0083] In this embodiment, the microstructures in the microstructure surface 32 of the ambient lighting structure 3 are pyramids, and the pyramids extend along the radial direction of the lens 2 to form pyramid strips, and all the pyramid strips are evenly arranged along the outer circumference of the lens 2 .

[0084] Example 4

[0085] like Figure 15-20 As shown, compared with Example 1, the specific structural forms of the reflective cup 1, the lens 2, and the atmosphere lighting structure 3 in this embodiment are different from those in Example 1.

[0086] In this embodiment, there are multiple reflective cups 1, for example, 2-5, and the multiple reflective cups 1 are arranged in a straight line to form a reflective cup plate.

[0087] The lenses 2 are arranged one-to-one with the reflective cups 1, that is, the number of lenses 2 and the reflective cups 1 are consistent, and the arrangement positions are also consistent. Therefore, the number of lenses 2 is also multiple, for example, 2-5, and the multiple lenses 2 are arranged in a straight line to form a lens plate.

[0088] The reflective cup plate and the lens plate can also be connected by snap fasteners or directly bonded.

[0089] The ambient lighting structure 3 is arranged on both sides of the lens plate and extends outward, wherein the reflective surface 31 can be arranged at the edge of the lens plate. The microstructures in the microstructure surface 32 extend along the length direction of the lens plate, and a plurality of microstructures are arranged in an array along the width direction of the lens plate, that is, the arrangement direction of the microstructure linear array is parallel to the arrangement direction of the lens 2.

[0090] In an optional implementation, the shape of the light emitting side of the reflective cup 1 is square, so the shape of the light incident surface 21 of the lens is square, and the two match each other, which can improve the utilization rate of light energy.

[0091] Example 5

[0092] like Figure 21-22 As shown, compared with Example 4, the specific structural form of the atmosphere lighting structure 3 in this embodiment is different from that in Example 4.

[0093] In this embodiment, the microstructures in the microstructure surface 32 of the atmosphere lighting structure 3 are pyramids and are evenly arranged along the microstructure surface 32 .

[0094] Example 6

[0095] like Fig.23 As shown, compared with Example 4, the specific structural form of the atmosphere lighting structure 3 in this embodiment is different from that in Example 4.

[0096] In this embodiment, the microstructure surface 32 of the atmosphere lighting structure 3 extends along the width direction of the lens plate, and a plurality of microstructures are arranged in an array along the length direction of the lens plate, that is, the linear array arrangement direction of the microstructures is perpendicular to the arrangement direction of the lenses 2 .
