Description

[Technical Field]

[0001] This utility model relates to the field of lighting fixture technology, and in particular to a lighting fixture with a dual-function lens. [Background Technology]

[0002] Traditional lighting fixtures generally employ a single optical structure, such as a lens, reflector, or diffuser. Their light distribution patterns are fixed, and their functions are limited, making it difficult to simultaneously meet the complex lighting needs of practical applications within a single fixture. For example, while floodlight lenses offer advantages such as uniform light diffusion, wide illumination range, and good glare control, making them suitable for creating comfortable and soft overall ambient light, their light intensity distribution is gradual, and their central illuminance is low, making it difficult to achieve high-brightness focusing on specific areas or objects, thus failing to meet the needs of accent lighting or visual guidance. Concentrating lenses, while offering advantages such as concentrated beams, high central illuminance, and strong directionality, are suitable for highlighting exhibits, signage, or work surfaces requiring high-brightness focusing. However, their beam edges are harsh, and the peripheral illuminance attenuates drastically, easily causing strong contrasts, visual fatigue, and even safety hazards. While reflector or diffuser structures can adjust the light pattern to some extent through secondary light distribution, they often rely on complex structures or sacrifice luminous efficiency, and are difficult to precisely control light distribution, let alone achieve coordinated output of focusing and floodlighting within a single component.

[0003] The limitations of a single optical structure are particularly prominent in scenarios where the requirements for lighting environment quality are increasingly demanding, such as commercial displays, home lighting, and industrial operations. Although the industry is currently trying to compensate for this by combining multiple luminaires, dividing lighting into zones, or using composite optical systems, these solutions generally suffer from problems such as complex structures, increased costs, light efficiency loss, inconsistent light distribution, and difficulties in installation and maintenance. [Utility Model Content]

[0004] The purpose of this invention is to provide a lighting fixture with a dual-function lens, which solves the problem that the current traditional single optical structure cannot meet the needs of composite lighting, while avoiding the problems of complex structure and low luminous efficiency caused by using multiple lamp combinations or composite optical systems.

Detailed Implementation Methods

[0025] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described in detail with reference to the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] Figure 1-7 The present invention discloses a lighting fixture with a dual-function lens, comprising a fixture body 1, wherein the fixture body 1 is provided with a light source substrate 2 for providing a lighting source and a lens body 3 disposed on the light-emitting side of the light source substrate 2 for improving light efficiency. The lens body 3 includes a floodlight portion 31 on the side close to the light source substrate 2 and a light-concentrating portion 32 on the side away from the light source substrate 2.

[0027] In this implementation, a light source is provided through a light source substrate, and a lens body is used to achieve both floodlighting and focusing effects. When the light source substrate emits light, the light first passes through the floodlight section on the near-light side of the lens body for wide-angle diffusion and uniform distribution, effectively improving the softness and coverage of ambient lighting, reducing glare, and creating a comfortable visual experience. At the same time, the light in the central area passes through the focusing section on the far-light side for high-density convergence and directional projection, significantly enhancing the illuminance of the target area and meeting the needs of focused lighting or visual guidance.

[0028] Furthermore, the light-concentrating part 32 is located in the central region of the lens body 3, and the floodlight part 31 is coaxially arranged with the light-concentrating part 32 and arranged in a ring around the light-concentrating part 32.

[0029] In this embodiment, the focusing section is located in the central region of the lens body, centered along the optical axis, and is used to converge the central beam to form a high-illuminance focused spot. The floodlight section is arranged in a ring around the focusing section, distributed in the outer ring area of ​​the lens body, and is used to receive the lateral light emitted by the ring-shaped sub-light source to achieve wide-angle uniform diffusion. Furthermore, the floodlight section and the focusing section are coaxially arranged within the lens body, with independent optical paths and coordinated functions, achieving a natural fusion of ambient light and accent light within a single optical component, avoiding the shortcomings of traditional luminaires with single functions or multiple lamp combinations.

[0030] Furthermore, the floodlight section 31 includes a plurality of cup-shaped structural sections 311 for improving light efficiency.

[0031] In this implementation, each cup-shaped structure constitutes an independent micro-optical unit, which can guide the large-angle chaotic light emitted by the light source to a preset floodlight angle through its precise curved surface. Secondly, multiple cup-shaped structures are arranged in an array, and their emitted light fields are superimposed to form a ring-shaped floodlight surface with continuous and excellent uniformity of illuminance distribution. This effectively avoids the phenomenon of "overly bright center and attenuated edges" common in traditional diffusion structures, and significantly improves the visual comfort and lighting efficiency of the floodlight area.

[0032] Furthermore, the outer surface of the cup-shaped structure 311 is provided with a plurality of evenly arranged grid protrusions 312.

[0033] In this implementation, by adjusting the height, spacing, tilt angle, and cross-sectional shape of the grille protrusions, the light can be refracted or scattered twice, and the light intensity distribution and light emission angle in the local area can be precisely controlled, thereby flexibly adapting to the optical needs of different application scenarios.

[0034] Furthermore, the light source substrate 2 includes a first light source substrate 21 that provides a light source to the floodlight section 31 and a second light source substrate 22 that provides a light source to the light-concentrating section 32.

[0035] In this embodiment, a first light source substrate provides light to the floodlight section, achieving uniform and soft wide-angle illumination, while a second light source substrate provides light to the focusing section, achieving a focused beam with high illuminance and high directivity. Through the dual-substrate design of physical separation and functional specialization, precise matching between the light source output and the optical structure is achieved, avoiding light energy mismatch and loss, and significantly improving the luminous efficacy of the luminaire.

[0036] Furthermore, the first light source substrate 21 is provided with a secondary lamp bead 211 corresponding to the cup body structure portion 311.

[0037] Furthermore, the second light source substrate 22 is provided with a main lamp bead 221 corresponding to the light-concentrating part 32.

[0038] Furthermore, a heat sink 4 for heat dissipation is provided between the first light source substrate 21 and the second light source substrate 22.

[0039] In this embodiment, by placing the heat sink between the first light source substrate and the second light source substrate to form a sandwich structure, the high-heat-density second light source substrate is in direct contact with the heat sink, which significantly shortens the heat conduction path, reduces thermal resistance, and effectively blocks lateral thermal crosstalk between the two light source substrates.

[0040] Furthermore, the lens body 3 is provided with a connector 33 for connecting the first light source substrate 21 on the side near the light source substrate 2, and the first light source substrate 21 is provided with a connection hole 212 that matches the connector 33.

[0041] Furthermore, the lamp body 1 includes a housing 11 for accommodating the light source substrate 2 and the lens body 3, and a front cover 10 and a base 12 respectively connected to the housing 11.

[0042] This utility model relates to a lighting fixture with a dual-function lens. The light source is provided by a light-emitting substrate, and the lens body achieves both floodlighting and focusing effects. When the light-emitting substrate emits light, the floodlight section on the side of the lens body closest to the substrate achieves wide-angle diffusion and uniform distribution of the light, effectively improving the softness and coverage of ambient lighting, reducing glare, and creating a comfortable visual experience. The focusing section on the side of the lens body furthest from the substrate achieves high-density convergence and directional projection of the central beam, significantly enhancing the illuminance of the target area and meeting the needs of focused lighting or visual guidance. This solves the problem that traditional single optical structures cannot meet the needs of composite lighting, while avoiding the problems of complex structure and low luminous efficiency associated with using multiple lamp combinations or composite optical systems.
