Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an LED optical structure and a lighting fixture using the structure. Background Technology

[0002] Eye-friendly LED lighting fixtures are attracting increasing attention from consumers, with low power consumption, wide angle, broad coverage, high illuminance, and anti-glare optical solutions being key technologies. In some conventional LED lighting fixtures, wide angle, broad coverage, and high illuminance are often achieved by increasing power consumption, with additional light shields used to mitigate glare. This approach is not only energy-wasting and inefficient, but also presents a significant challenge in applications with energy consumption and long battery life requirements, such as rechargeable and solar-powered lighting. Furthermore, in existing LED lighting technologies, when not emitting light, the PCB circuitry and unrelated optical structures are visible from the outside in, affecting the product's aesthetics. Utility Model Content

[0003] The purpose of this invention is to achieve a wide-angle, wide-area, and high illuminance light emission from the light source while improving glare, without increasing power consumption, by rationally setting the optical structure of the lamp.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an LED optical structure, including a lamp head cover and a lamp head formed by a lens, and a light source assembly disposed within the lamp head. The light source assembly includes a PCB board and an LED light source. An array of LED light sources is disposed on the surface of the PCB board facing the lens. The surface of the lens facing the PCB board forms multiple protruding structures. The protruding structures are arranged in a leaf-like or bauhinia-like diffusion pattern from the center outward. The light-emitting surface of the lens forms an inwardly concave annular wave structure. The light emitted by the LED light source can improve the glare of the light source spot and achieve a larger angle of polarization by passing the light emitted through the lens.

[0005] Preferably, the LED light sources are arranged in a centrally symmetrical manner, and the light-emitting surface of the LED light sources is projected onto the surface of the lens facing the PCB board at the boundary between the protruding structures.

[0006] An LED lamp includes a lamp head, the lamp head including the LED optical structure as described above, one end of the lamp head is connected to a goose tube, the other end of the goose tube is connected to the lamp base, the lamp base is provided with a power supply for the lamp, and the PCB board is electrically connected to the power supply of the lamp base through the goose tube.

[0007] Preferably, the lamp base is a clip structure, the clip structure includes an upper clip and a lower clip, and the housing where the power supply is located is configured as the upper clip.

[0008] Preferably, the upper surface of the housing containing the power supply is provided with the control components of the lamp.

[0009] Preferably, the bottom of the lower clamping piece is provided with a base pad.

[0010] Preferably, the control component includes a sensing spring.

[0011] The present invention has the following beneficial effects: When the LED lamp is not lit, the beaded surface (protruding structure) arranged in a leaf-like or bauhinia flower-like diffusion pattern from the center outward can effectively reduce the visibility of the internal PCB circuit and unrelated optical structures when viewed from the outside in; when the LED lamp is lit, it has a good polarization effect, beautiful light quality, and good anti-glare effect.

[0023] The following are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the following embodiments. All technical solutions that fall within the scope of this utility model are protected.

[0024] Reference manual attached Figure 1-3 An LED lamp includes a lamp head, in which a light source assembly 12 is disposed. One end of the lamp head is connected to a goose tube 10, which is fixed to the mounting holes of the lamp head cover 11 and the battery compartment lower cover 6 by glue or threads. The light source assembly 12 is fixed to the lamp head cover 11 by heat-sealing pins, glue, or screws. A lens 13 is fixed to the lamp head cover 11 by clips. A battery 7 and foam 8 are placed in the battery compartment lower cover 6. A control assembly 15 is fixed to the battery compartment lower cover 6 by screws 14. A battery compartment upper cover 9 is fixed to the battery compartment lower cover 6 by screws 16 and clips. Clip feet 17 are attached to the battery compartment lower cover 6 by adhesive. The battery compartment cover 6 and clip feet 17 are attached to the base 2 with adhesive backing. The base feet 1 are also attached to the base 2 with adhesive backing. The base 2 is assembled with the battery compartment cover 6 via screws 4, springs 5, and nuts 18 to form an openable clip structure. The decorative piece 3 is attached to the base 2 with adhesive backing, completing the assembly of the entire machine. The light source assembly 12 is electrically connected to the control assembly 15 via wires passing through the goose tube 10 and the battery compartment cover 6. The battery 7 is also electrically connected to the control assembly 15 via wires. When the button position on the battery compartment cover 9 is touched, the sensing spring of the control assembly 15 can receive a sensing signal and provide a functional feedback signal to the entire machine.

[0025] Reference manual attached Figure 2-3The lamp head has an optical structure, including a lamp head cover 11, a lamp head 13 formed by a lens, and a light source assembly 12 disposed within the lamp head. The inner surface of the lens 13 has a polarizing optical structure with a bead-like protrusion structure 122. The protrusion structure 122 is arranged in a leaf-like or bauhinia flower-like diffusion pattern from the center outwards. The outer surface of the lens 13 forms an inwardly concave annular wave structure 123. When the LED light is not lit, from the outside in, the bead-like arrangement of the leaf-like or bauhinia flower-like diffusion pattern can effectively reduce the visibility of the internal PCB circuit and irrelevant optical structures. When the LED light is lit, through the arrangement design of the LED light source, the light-emitting surface of the LED light source is projected at the point where the two bead-like surfaces overlap. The light from the LED light can be fully polarized, presenting a polarization effect and beautiful light quality under the combined effect of leaf-like arrangement and light source arrangement, effectively improving the glare of the light spot and achieving polarization at a larger angle.

[0026] LED light sources can be arranged in various ways. By simply projecting the light-emitting surface of the LED light source onto the surface of the lens facing the PCB board at the boundary between the raised structures, a good polarization effect, a beautiful light quality, and a good anti-glare effect can be achieved.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model.
