Description

Technical Field

[0001] This utility model relates to the field of floodlight technology, and in particular to a wide-angle LED floodlight. Background Technology

[0002] This paper introduces the technical requirements for lighting fixtures in outdoor architectural and landscape lighting projects. With the increasing demands for quality urban nightscapes, outdoor lighting projects not only need to meet basic functional lighting requirements but also pursue broad, uniform, and dark-area-free light coverage, while also considering ease of installation and maintenance, energy efficiency, and the visual aesthetic of "seeing the light but not the lamp." This places higher demands on the luminous angle, light field uniformity, and structural adaptability of LED floodlights, which are the core lighting tools.

[0003] Currently, most mainstream LED floodlights on the market adopt a planar light-emitting surface design, with their LED light source array and matching optical lenses fixedly mounted on a flat substrate. After being distributed by optical elements, the light is mainly concentrated and projected forward, forming a relatively focused beam. To cover a wider area, multiple lights are usually installed in different locations and combined together.

[0004] However, existing lighting fixtures, based on conventional schemes of planar light emission and fixed angle adjustment, have a fundamental drawback: the effective illumination angle of a single lamp is limited, making it difficult to achieve uniform floodlighting over a wide area. To meet the lighting needs of spacious areas such as plazas and building facades, it is necessary to significantly increase the number of lamps and deploy them densely. This directly leads to a substantial increase in equipment costs, installation complexity, and subsequent energy consumption and maintenance costs, which contradicts the current green, energy-saving, simple, and efficient lighting design philosophy. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a wide-angle LED floodlight.

[0006] This application provides a wide-angle LED floodlight, including a main lamp body, and further comprising: The light source mechanism is located in the middle of the main lamp body; The light source mechanism includes a light source module lamp body located in the middle of the main lamp body, and the light source module lamp body is installed in the middle of the main lamp body by light source module lamp body screws. An LED integrated circuit board is installed at the bottom of the light source module lamp body by circuit board fastening screws. Multiple lenses are installed on the upper surface of the LED integrated circuit board, and the multiple lenses are connected by connecting wires. A back cover is provided at the bottom of the main lamp body. An electric light source driving module is provided between the back cover and the light source module lamp body.

[0011] Optionally, the angle adjustment mechanism includes a lamp bracket, which is rotatably mounted at the bottom of the rear cover, and a bracket adjustment screw is rotatably mounted at the top of the lamp bracket.

[0012] Optionally, one side of the outer wall of the bracket adjusting screw is threaded to the bottom of the rear cover.

[0013] In summary, this application includes at least one of the following beneficial technical effects: This invention utilizes an innovative arc-shaped light-emitting surface, enabling a single lamp to achieve the wide-range uniform illumination that traditional solutions require multiple lamps, significantly reducing the number of lamps needed and lowering overall costs. Furthermore, the innovative arc-shaped light-emitting surface and adjustable light-shielding structure allow a single lamp to achieve the same wide-range uniform illumination as traditional solutions, further reducing the number of lamps needed and lowering overall costs.

[0017] 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.

[0018] like Figures 1-6 As shown, the present invention proposes a wide-angle LED floodlight, which includes a main lamp body 1 and a light source mechanism; in one embodiment, the light source mechanism is located in the middle of the main lamp body 1; The light source mechanism includes a light source module lamp body 7 located in the middle of the main lamp body 1. The light source module lamp body 7 is installed in the middle of the main lamp body 1 by light source module lamp body screws 8. An LED integrated circuit board 9 is installed at the bottom of the light source module lamp body 7 by circuit board fastening screws 10. Multiple lenses 4 are installed on the upper surface of the LED integrated circuit board 9, and the multiple lenses 4 are connected by connecting wires 5. A back cover 14 is provided at the bottom of the main lamp body 1. An electric light source drive module 13 is provided between the back cover 14 and the light source module lamp body 7. A cable waterproof connector 15 is installed at both ends of the bottom of the back cover 14, and a cable 16 is provided inside the cable waterproof connector 15. The floodlight also includes an aluminum cover 2 with multiple ventilation holes inside, and the aluminum cover 2 is installed on the top of the main lamp body 1 by cover screws 3. Multiple heat dissipation holes 19 are provided at both ends of the main lamp body 1. A two-component waterproof adhesive 6 is used to fill the space between the lens 4 and the light source module lamp body 7. A rear cover 14 is installed at the bottom of the main lamp body 1 by rear cover fastening screws 12. A waterproof silicone pad 11 is provided between the main lamp body 1 and the rear cover 14. The following is a detailed description of the LED floodlight: In this embodiment, an external power supply is connected to the lamp via cable 16 and a waterproof cable connector 15. The waterproof cable connector 15 first ensures a sealed and waterproof connection at the inlet. Electrical energy is then delivered to the light source driver module 13, which is installed above the space between the rear cover 14 and the waterproof silicone pad 11. The light source driver module 13 converts the mains power into a constant current suitable for LED operation and provides overvoltage and overcurrent protection for the circuit before transmitting the power to the LED integrated circuit board 9. The LED integrated circuit board 9 is securely mounted on the bottom plane of the light source module lamp body 7 using circuit board fastening screws 10. Multiple LED chips integrated on the board emit light when powered on. A lens 4 is press-fitted onto each LED chip, and the lenses 4 are connected and positioned by connecting wires 5. A two-component waterproof potting compound 6 is filled in the gap between the lens 4 and the light source module lamp body 7, and after curing, forms an integrated sealed and waterproof structure, ensuring that the core of the light source is not affected by a humid environment, while also fixing the lens 4 and providing initial light guidance. The light source module lamp body 7, as an independent heat dissipation unit, is tightly installed in the middle cavity of the main lamp body 1 by the light source module lamp body screw 8, ensuring that the heat generated can be effectively conducted to the main lamp body 1.

[0019] The light emitted by the LED first undergoes optical distribution through lens 4. Because multiple lenses 4 are arranged in an array and the mounting surface of the light source module lamp body 7 is designed to adapt to a specific tilt angle for wide-angle illumination, the emitted light has a natural diffusion tendency, achieving basic wide-angle projection.

[0020] The large amount of heat generated during lamp operation is dissipated through the following pathways: heat from the LED chip is conducted to the LED integrated circuit board 9, and then to the metal light source module body 7 and the main lamp body 1. The main lamp body 1 serves as the primary heat sink, with heat dissipation holes 19 at both ends and multiple ventilation holes on the top aluminum cover 2 forming an efficient airflow channel. Internal hot air rises and is exhausted through the ventilation holes on the aluminum cover 2, while external cool air is drawn in through gaps at the bottom or sides of the lamp body, creating continuous convection and significantly improving overall heat dissipation efficiency. The aluminum cover 2 is secured with cover screws 3, ensuring unobstructed ventilation.

[0021] Finally, the optical module is sealed and protected by the back cover 14, which is connected to the main lamp body 1 by the back cover fastening screws 12. A waterproof silicone pad 11 is pressed between them to form a second waterproof sealing barrier to protect the internal components such as the electric light source drive module 13.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, the LED floodlight also includes an angle adjustment mechanism; in one embodiment, the angle adjustment mechanism includes a lamp bracket 17, which is rotatably disposed at the bottom of the rear cover 14, and a bracket adjustment screw 18 is rotatably disposed at the top of the lamp bracket 17. The bracket adjusting screw 18 is threaded to the bottom of the rear cover 14 on one side of its outer wall. The angle adjustment mechanism is described in detail below: In this embodiment, the lamp bracket 17 is hinged to the bottom of the rear cover 14 via a pivot, so that the rear cover 14 can rotate relative to the lamp bracket 17 in the pitch direction.

[0023] The bracket adjustment screw 18 is a key component for achieving angle adjustment and locking. One end of the bracket adjustment screw 18 is threaded to the bottom of the back cover 14, and the other end is connected to the top of the lamp bracket 17 through a connection that allows free rotation.

[0024] When it is necessary to adjust the pitch angle of the lamp, the operator rotates the screw 18 of the bracket adjustment screw, which is threadedly connected to the back cover 14. Therefore, the screw 18 of the bracket adjustment screw is screwed in or out relative to the back cover 14.

[0025] Rotating the bracket adjusting screw 18 clockwise into the nut seat at the bottom of the rear cover 14 shortens its effective length, thereby pulling the upper part of the lamp bracket 17 closer to the lamp body, forcing the lamp body to rotate downwards around the hinge axis, thus lowering the illumination angle. Conversely, rotating the bracket adjusting screw 18 counterclockwise unscrews it, increasing the effective illumination length and pushing the upper part of the lamp bracket 17 away from the lamp body, causing the lamp body to tilt upwards.

[0026] 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.
