The same reference numerals used throughout the drawings indicate the same or similar parts.

[0034] Reference Figures 1 to 5 , a highly uniform scene light, comprising: a metal substrate 1, a light-emitting group 2, a lens 3 and a lampshade 4;

[0035] In one embodiment, the light-emitting group 2 is fixed on the metal substrate 1, the lens 3 is covered on the light-emitting group 2, the lampshade 4 is located above the lens 3 and the metal substrate 1, the light-emitting group 2 includes a plurality of annular light strips, the annular light strips diverge from the center to the edge of the metal substrate 1, and the annular light strips include a plurality of chips. Preferably, the lens 3 is an integrated lens 3.

[0036] Among them, the chip is fixed on the metal substrate 1 from the inside to the outside in the form of a circular sleeve, and the chip is covered by a lens 3. The lens 3 includes an optical boss 31 set corresponding to the chip. The size of the optical boss 31 changes with the divergence distance of the annular light strip. It has a gradient array optical structure feature and is used to process the light when the chip emits light. The optical boss 31 is provided with an exit surface and an incident surface. The light emitted by the chip enters from the incident surface and diverges from at least one exit surface after refraction. By arranging the chips in multiple layers in an annular manner and matching the optical boss 31 with a gradient structure, when the light-emitting groups 2 of different light colors emit light alone or in cascade, the lighting effect and lighting quality are improved, glare is prevented, and visual comfort is improved. This high-uniformity scene lighting has the characteristics of high uniformity of the illuminated surface, low glare value, and good overall visual experience.

[0037] In one embodiment, the lens 3 includes an optical boss 31 arranged corresponding to the chip, and the optical boss 31 is provided with an exit surface and an incident surface. The light emitted by the chip enters from the incident surface and diverges from at least one exit surface after being refracted. The size of the optical boss 31 changes with the divergence distance of the annular light strip, and the optical boss 31 corresponding to each annular light strip is equal in size and shape.

[0038] In one embodiment, the lens 3 further comprises a base 32 fixedly connected to the optical boss 31 , and a reflective surface 318 is further provided at one end of the optical boss 31 connected to the base 32 ; the reflective surface 318 is provided with three-dimensional etching.

The L1 light emitted by the chip passes through the first incident surface 316 of the optical boss 31, wherein the first incident surface 316 is provided with a smooth parabolic arc surface. When the L1 light passes through the smooth parabolic arc surface provided on the first incident surface 316, it propagates radially along the smooth parabolic arc surface to become the L1-1 light. The L1-1 light propagates in the optical boss 31 to the fourth exit surface 315. When the L1-1 light passes through the fourth exit surface 315, it is optically reflected and refracted, and then decomposed into the L1-2 light and projected onto the lampshade 4. After propagating through the optical boss 31, the light L1-3 is reflected to the third exit surface 314; after being refracted and reflected by the third exit surface 314, the light L1-3 is decomposed into the light L1-4 and projected onto the lampshade 4, and decomposed into the light L1-5 and projected onto the reflective surface 318 through the optical boss 31; after being reflected and diffusely reflected by the first reflective surface 318, the light L1-5 becomes the light L1-6 and is projected onto the third exit surface 314 through the optical boss 31, and the generated light L1-7 is projected onto the lampshade 4.
