Description

Technical Field

[0001] This utility model relates to the field of point light source lighting technology, and in particular to an LED point light source lighting fixture. Background Technology

[0002] In the field of architectural landscape lighting, LED point light sources are widely used due to their flexibility and energy-saving advantages. Their core value lies in highlighting the architectural structure and aesthetic features through light and shadow. Ideal lighting effects require luminaires to present a uniform, soft, and glare-free light spot at night, while being as inconspicuous as possible during the day, blending seamlessly with the building's form, texture, and color to avoid visually disrupting the building's original daytime appearance. This places extremely high demands on the optical design and structural integration of the luminaires.

[0003] Currently, most LED point light sources on the market, in pursuit of versatility and low cost, adopt standardized exposed mounting structures, that is, fixing the lamp body to the building surface through independent brackets or bases. Their optical processing is usually relatively simple, often using a transparent or semi-transparent cover with regular ridges (such as rhombuses) directly covering the LED beads, relying on the simple refraction and diffusion of the cover itself to adjust the light output.

[0004] However, traditional LED point light sources, with their simple diamond-shaped covers and other structures, have limited light processing capabilities and cannot effectively eliminate the strong point-emitting characteristics of LED chips. This results in glaring light with noticeable graininess and light spots when viewed at close range or from specific angles, leading to poor visual comfort. Furthermore, the exposed installation method and independent fixture form make them stand out prominently from the building surface, appearing jarring during the day and severely disrupting the overall integrity and pure aesthetics of the building's appearance. In short, they suffer from poor light quality, visual abruptness, and difficulty in achieving aesthetic integration with the architecture. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an LED point light source lamp.

[0006] This application provides an LED point light source lamp, including a building circular tube and a circular tube end installed at one end of the building circular tube, and further including: Light source mechanism; located at the end of the circular tube away from the building's circular tube; The light source mechanism includes a lamp body disposed at one end of a circular tube. An LED integrated circuit board is disposed in the inner cavity of the lamp body. An optical lens and an optical acrylic diffuser are disposed on one side of the LED integrated circuit board. Waterproof sealant is filled in the assembly gap between the optical acrylic diffuser and the lamp body. A waterproof connector is installed at the rear end of the lamp body, and the waterproof connector is electrically connected to the LED integrated circuit board via a cable.

[0007] Optionally, the end of the round tube is fixedly connected to the lamp body with adhesive.

[0008] Optionally, the LED integrated circuit board is installed in the inner cavity of the lamp body by circuit board fixing screws.

[0009] Optionally, the optical lens and the optical acrylic diffuser are sequentially arranged in the light-emitting direction of the LED integrated circuit board.

[0010] Optionally, the optical lens and the optical acrylic diffuser are encapsulated in the optical window at the front of the lamp body.

[0011] Optionally, the inner cavity of the lamp body, the LED integrated circuit board, and its electrical connection points are all filled with potting two-component waterproof adhesive.

[0012] In summary, this application includes at least one of the following beneficial technical effects: This invention abandons the traditional glaring diamond-shaped cover design and innovatively uses optical-grade acrylic diffusion material on the light-emitting surface, combined with a scientifically designed optical lens, to perform secondary light distribution and full diffusion of the light emitted by the LED. This effectively eliminates glare and graininess when viewed at close range, achieving a high-quality light spot that is uniform, soft, and free of spots, significantly improving visual comfort and lighting quality.

[0013] Furthermore, by employing a dual sealing solution combining internal potting compound with multiple external sealing gaskets, comprehensive waterproofing, moisture-proofing, and insulation protection for the circuitry is achieved, significantly improving the long-term reliability and lifespan of the lighting fixtures in harsh outdoor environments.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-3 As shown, the present invention proposes an LED point light source lamp, which includes a building tube 1, a tube end 2, and a light source mechanism; in one embodiment, the tube end 2 is installed at one end of the building tube 1; the light source mechanism is located at the end of the tube end 2 away from the building tube 1. The light source mechanism includes a lamp body 4 disposed at one end of the round tube end 2. An LED integrated circuit board 8 is disposed in the inner cavity of the lamp body 4. An optical lens 10 and an optical acrylic diffuser plate 12 are disposed on one side of the LED integrated circuit board 8. Waterproof sealant 11 is filled in the assembly gap between the optical acrylic diffuser plate 12 and the lamp body 4. A waterproof connector 5 is installed at the rear end of the lamp body 4, and the waterproof connector 5 is electrically connected to the LED integrated circuit board 8 through a cable 6. The round tube end 2 is fixedly connected to the lamp body 4 by adhesive 3; the LED integrated circuit board 8 is installed in the inner cavity of the lamp body 4 by circuit board fixing screws 7; the optical lens 10 and the optical acrylic diffuser plate 12 are arranged sequentially in the light emission direction of the LED integrated circuit board 8; the optical lens 10 and the optical acrylic diffuser plate 12 are encapsulated in the optical window at the front of the lamp body 4; the inner cavity of the lamp body 4, the LED integrated circuit board 8 and its electrical connection points are all filled with potting two-component waterproof adhesive 9. The following is a detailed description of the light source and lamp fixture: In this embodiment, when an external power source supplies power to the LED integrated circuit board 8 through the cable 6 introduced by the waterproof connector 5, the onboard LED chip is lit up, emitting initial light. The light first strikes the optical lens 10. As a primary optical element, the optical lens 10 performs initial light distribution and control on the point light source or small-area light source emitted by the LED chip. The light, initially shaped by the optical lens 10, then reaches the optical acrylic diffuser plate 12. As an optical element, the optical acrylic diffuser plate 12 utilizes the light-scattering particles inside the material and the surface microstructure texture to perform multiple scattering and diffuse reflection of the incident light. This process enables the light emitted from the optical lens 10 to form a uniform, soft, and glare-free surface light source effect on the light-emitting surface.

[0018] Furthermore, during the later stages of lamp assembly, a two-component waterproof adhesive 9 is injected into the inner cavity of the lamp body 4 in liquid form. The liquid adhesive automatically fills and coats the LED integrated circuit board 8, all electronic components, solder joints, and the internal connections of the cables 6, leaving no air bubbles or gaps. After curing, it forms a complete inner-lined waterproof and insulating barrier. On the one hand, it prevents condensation or slight water seepage from forming inside the cavity and contacting the circuit, thus preventing short circuits; on the other hand, the adhesive acts as a buffer to protect the circuit board and components, resisting vibration and impact. At the same time, it conducts heat from the LED chip to the lamp body 4 housing, assisting in heat dissipation.

[0019] Waterproof sealant 11 is filled at the seam where the optical acrylic diffuser plate 12 and the front optical window of the lamp body 4 are pressed together. This effectively prevents rainwater and dust from entering along the seam, protecting the internal optical components and keeping them clean and dry.

[0020] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
