Description

Technical Field

[0001] This utility model relates to the field of wall washer technology, and in particular to an LED wall washer for floodlighting. Background Technology

[0002] Wall washer lights, as the name suggests, are designed to evenly cover and "wash" the wall surface like flowing water, creating a soft and uniform lighting effect. Their primary purpose is architectural decorative lighting, enhancing the overall aesthetics and visual appeal of a building through clever use of light. Wall washer lights not only provide basic illumination but also, through their unique light effects, create a layered and dynamic interplay of light and shadow on the walls. Furthermore, they are often used to outline and highlight the contours of buildings, making them appear more magnificent and eye-catching at night, adding to the charm of the city's nightscape.

[0003] Due to their energy-saving, high luminous efficacy, rich colors, and long lifespan, LED wall washer lights have gradually become the mainstream choice in the market. The application of LED technology not only reduces energy consumption but also provides more color options and a longer lifespan, significantly improving both the functionality and aesthetics of wall washer lights. However, the relatively simple optical design of existing wall washer lights, such as those using planar structures, leads to significant light scattering and loss during propagation, resulting in relatively low luminous efficacy. This design deficiency often limits their practical application to low-rise buildings or small-scale lighting, failing to achieve wide-area, uniform floodlighting effects and restricting their application in high-rise buildings or large-scale landscape lighting. Therefore, improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing an LED wall washer light for floodlighting. The light has a simple and reasonable structure and is easy to operate. The cross-section of the light body is set in an inverted trapezoidal shape, which is narrow at the bottom and wide at the top, allowing more light to pass through and thus achieving higher luminous efficiency. This high luminous efficiency characteristic enables the LED wall washer light to achieve a wide-range and uniform floodlighting effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses an LED wall washer light for floodlighting, comprising a lamp body. From bottom to top, a lamp plate, a lens, and a glass plate are sequentially arranged on the top surface of the lamp body. A plurality of LED beads are arranged on the lamp plate. The cross-section of the lamp body is an inverted trapezoid. End caps are fixedly arranged at both ends of the lamp body, and a sealing gasket is provided between the end cap and the lamp body. The cross-sections of the end cap and the sealing gasket are adapted to the cross-section of the lamp body. A mounting bracket is provided on the lamp body, comprising an upper bracket and a lower bracket. The upper bracket is fixedly connected to the lamp body, and the lower bracket is hinged to the upper bracket via a connector. The lower bracket can rotate relative to the upper bracket. A locking nut for locking the position of the lower bracket is also provided on the connector.

[0007] Furthermore, a plurality of lenses are provided, and the lenses are located above the lamp beads and cooperate with the lamp beads accordingly.

[0008] Furthermore, the glass plate is provided with several through holes that correspond to and cooperate with the lens.

[0009] Furthermore, the LED beads are arranged along the length of the lamp panel.

[0010] Furthermore, the lamp body is provided with a female connector and a male connector, both of which are electrically connected to the lamp board and are fixedly connected to the lamp body by waterproof nuts.

[0011] Furthermore, the waterproof nut includes a first nut and a second nut. The first nut is provided with an upper threaded portion and a lower threaded portion. The upper threaded portion passes through the lamp body and is fixedly connected to the lamp plate. The second nut is fixedly connected to the lower threaded portion. A first rubber ring is provided between the upper threaded portion and the lamp plate. A second rubber ring is provided inside the second nut, and the upper end of the second rubber ring extends into the first nut.

[0012] Furthermore, the upper bracket is provided with a mounting groove, the mounting groove is U-shaped, and the connector is disposed in the mounting groove.

[0013] Furthermore, the lower bracket extends upward and is provided with a first leg and a second leg respectively. The first leg is provided with a first mounting hole, and the second leg is provided with a second mounting hole. The connector passes through the first mounting hole and the second mounting hole in sequence, and the locking nut is located on the outer side wall of the second leg.

[0014] Furthermore, a gasket is provided between the connector and the outer wall of the first leg.

[0015] Furthermore, the plug and the lamp body are fixedly connected by a first screw. The lamp body is provided with a connecting groove that mates with the first screw. The first screw passes through the plug and the sealing gasket in sequence and connects to the connecting groove.

[0016] The beneficial effects of this utility model are as follows: The LED wall washer light for floodlighting described in this utility model has an inverted trapezoidal cross-section, which is narrower at the bottom and wider at the top, allowing more light to pass through and thus achieving higher luminous efficacy. This high luminous efficacy characteristic enables the LED wall washer light to achieve a wide-range, uniform floodlighting effect. In addition, the LED beads and lenses work together to transform point light sources into surface light sources, allowing light to uniformly cover the illuminated surface (such as a wall). Furthermore, the lenses can optimize the distribution of light, effectively directing the light onto the wall and greatly reducing ineffective light scattering, thereby significantly improving the utilization efficiency of light. Compared with conventional LED wall washer lights, this utility model has higher luminous flux at the same power or lower energy consumption at the same brightness, which can reduce long-term operating costs.
