Description

Technical Field

[0001] This utility model belongs to the technical field of lighting accessories, specifically relating to polarizing lenses and lighting fixtures. Background Technology

[0002] In existing indoor lighting systems, especially those designed to diffuse light to the ceiling, a common problem is limited illumination range. Traditional luminaire designs often direct light directly onto the ceiling above the fixture without adequately considering outward diffusion and dispersion. This results in overly concentrated light distribution within the room, primarily focused on the area directly below the fixture, while areas further away remain poorly lit. This not only affects the overall lighting effect but can also lead to uneven brightness within the space, impacting comfort and visual experience for both living and working. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that existing light fixtures that scatter light to the ceiling do not fully consider the outward diffusion and deflection of light, resulting in unsatisfactory indoor lighting effects, and to provide a polarizing lens and light fixture with outward deflection of light.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A polarizing lens includes a lens body, which is integrally formed. The lens body comprises, from front to back, a first lens portion and a second lens portion. The bottom of the lens body has a receiving cavity with a bottom opening and a reflecting cavity. The receiving cavity is used to house a light source. The outer surface of the first lens portion is curved. The rear top side of the second lens portion has a first light-blocking protrusion, and the rear side of the first light-blocking protrusion has a second light-blocking protrusion. The height of the second light-blocking protrusion is greater than the height of the first light-blocking protrusion. The receiving cavity is located at the bottom of the first and second lens portions. The reflecting cavity is located at the bottom of the second light-blocking protrusion. The portion of the inner wall of the receiving cavity corresponding to the first lens portion forms a first incident surface. The outer side of the first lens forms a first exit surface, and the first lens portion is used to refract the light transmitted from the first incident surface outward and forward and exit through the first exit surface; the portion of the inner wall of the accommodating cavity corresponding to the second lens portion is the second incident surface, the front side of the first light-blocking protrusion is the vertically arranged second exit surface, and the rear side of the first light-blocking protrusion is the first total reflection surface arranged obliquely upward, which is used to reflect the light transmitted from the second incident surface to the second exit surface for exit; the top of the second light-blocking protrusion is the third exit surface, and the inner wall of the reflecting cavity facing the accommodating cavity is the second total reflection surface, which is used to reflect part of the light transmitted from the second incident surface to the third exit surface for exit.

[0006] Compared with existing technologies, the polarizing lens of this invention includes a first lens portion and a second lens portion, as well as a first light-blocking convex portion and a second light-blocking convex portion disposed on the top and rear side of the second lens portion. When the light source within the cavity generates light, the first lens portion refracts the light outward through its curved outer surface, expanding the illumination range. The second lens portion, through the cooperation of the first and second light-blocking convex portions, and the placement of a first total reflective surface, a reflecting cavity, and a second total reflective surface, further guides the light to scatter forward, ensuring sufficient illumination even in locations far from the light fixture. Furthermore, this invention effectively utilizes light that might otherwise be wasted through the reflection of the first and second total reflective surfaces, improving light utilization efficiency. This design not only makes indoor lighting more uniform but also significantly enhances the comfort and visual experience of living or working in the space.

[0007] Furthermore, the inner wall of the reflecting cavity facing the accommodating cavity is an inner arc surface; this arrangement concentrates part of the light transmitted from the second incident surface and emits it together towards the third exiting surface, resulting in a better outward refraction effect of the light.

[0008] Furthermore, the first fully reflective surface is a plane, and the angle between the first fully reflective surface and the horizontal plane is 50 to 70°. By setting it in this way, the first fully reflective surface can reflect the light source, change the trajectory of the light path, and provide uniform light diffusion.

[0009] Furthermore, the third emission surface is a horizontal plane, and the front side of the second light-blocking protrusion is a vertical plane; with this arrangement, the second total reflection surface can reflect the light source, change the trajectory of the light path, and provide uniform light diffusion.

[0010] Furthermore, the thickness of the first lens portion gradually increases from back to front; with this arrangement, the first lens portion effectively disperses the light transmitted from the first incident surface, resulting in good light scattering effect.

[0011] The lamp includes a lamp body, a light-transmitting ring cover, and the aforementioned polarizing lens. The lamp body has a hanging bracket on its top, and an annular lamp groove is provided on the outer side of the top of the lamp body. Several mounting slots are provided circumferentially inside the annular lamp groove. Each mounting slot is equipped with a light-emitting element and a polarizing lens for covering the light-emitting element. The first lens portion of the polarizing lens is arranged facing outward, and the light-transmitting ring cover is used to cover the annular lamp groove.

[0012] Compared with existing technologies, the lamp of this invention includes a polarizing lens for cooperating with the light-emitting element, comprising a first lens portion and a second lens portion, as well as a first light-blocking convex portion and a second light-blocking convex portion disposed on the top and rear side of the second lens portion. When the light source within the cavity generates light, the first lens portion refracts the light outward through its curved outer surface, expanding the illumination range. The second lens portion, through the cooperation of the first and second light-blocking convex portions, and the placement of a first total reflective surface, a reflecting cavity, and a second total reflective surface, further guides the light to scatter forward, ensuring sufficient illumination even at locations far from the lamp. Furthermore, this invention effectively utilizes light that might otherwise be wasted through the reflection of the first and second total reflective surfaces, improving light utilization efficiency. This design not only makes indoor lighting more uniform but also significantly enhances the comfort and visual experience of living or working in the room. Attached Figure Description

[0024] See Figures 1 to 8 The present invention discloses a polarizing lens, comprising a lens body 1, which is integrally formed. The lens body 1 includes, from front to back, a first lens portion 11 and a second lens portion 12. The bottom of the lens body 1 has a receiving cavity 13 with a bottom opening and a reflecting cavity 14. The receiving cavity 13 is used to place a light source.

The receiving cavity 13 is located at the bottom of the first lens portion 11 and the second lens portion 12. The reflecting cavity 14 is located at the bottom of the second light-blocking protrusion 16. The inner wall of the receiving cavity 13 corresponding to the first lens portion 11 forms a first incident surface 111. A first exit surface 112 is formed on the outer side of a lens. A first lens portion 11 is used to refract the light transmitted from the first incident surface 111 outward and forward and emit it through the first exit surface 112. The portion of the inner wall of the accommodating cavity 13 corresponding to the second lens portion 12 is the second incident surface 121.

The rear side of the first light-blocking protrusion 15 is a first total reflection surface 151 arranged obliquely upward.

When the light source within the accommodating cavity 13 generates light, the first lens portion 11 refracts the light outward through its curved outer surface, expanding the illumination range.

Furthermore, this invention effectively utilizes light that might otherwise be wasted through the reflection of the first total reflective surface 151 and the second total reflective surface 141, improving light utilization efficiency. This design not only makes indoor lighting more uniform but also significantly enhances the comfort and visual experience of living or working in the space. In addition, the height of the second light-blocking protrusion 16 is greater than the height of the first light-blocking protrusion 15, so that as much light as possible can be refracted by the first total reflection surface 151 and emitted from the second emission surface 152.
