Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a linear light. Background Technology

[0002] LED linear lights are one of the main types of lighting fixtures commonly used in outdoor landscaping projects. Due to errors in manufacturing and assembly processes, gaps usually exist between the cover plate and the lamp housing, resulting in poor sealing performance. Moisture and dust can easily penetrate these gaps and enter the lamp housing, affecting the lifespan of the linear lights. Utility Model Content

[0003] The purpose of this invention is to provide a linear light with high overall sealing performance, which can improve installation efficiency, effectively reduce light spots and expand the lighting coverage, optimize light uniformity and diffusion effect, and avoid glare.

[0004] To achieve the above objectives, this utility model provides a linear light, including a lamp housing, an LED bead plate, and a lens cover plate. The lamp housing has sealing end plates at both ends and a light-emitting cavity. The upper left and right sides of the light-emitting cavity have mounting grooves. The LED bead plate is installed inside the light-emitting cavity. The lens cover plate is an integral structure, comprising a lens body and a diffuser cover plate. The lens body is positioned below the diffuser cover plate and has an inverted trapezoidal structure. Both sides of the top of the lens body have locking strips that engage with the mounting grooves. The diffuser cover plate covers the top surface of the light-emitting cavity, which is filled with sealing colloid.

[0005] As a preferred embodiment of this utility model, the thickness of the lens body is greater than half the depth of the light-emitting cavity.

[0006] As a preferred embodiment of this utility model, the diffusion cover is a milky white diffusion cover.

[0007] As a preferred embodiment of this utility model, the top surface of the diffusion cover is frosted.

[0008] As a preferred embodiment of this utility model, a guide arc surface is provided between the outer side of the card strip and the lens body of the lens body.

[0009] As a preferred embodiment of this utility model, the cross-sectional area of ​​the card strip is smaller than the cross-sectional area of ​​the mounting groove.

[0010] As a preferred embodiment of this utility model, the bottom of the lamp housing is provided with a wire placement cavity.

[0011] Compared with the prior art, the linear light of this utility model has the following advantages:

[0012] This invention fills the light-emitting cavity with sealing colloid, ensuring that the gap between the lens cover and the lamp housing is completely filled with the sealing colloid. Simultaneously, the sealing colloid covers the LED chip plate, guaranteeing high overall sealing performance of the linear light. The lens cover is secured to the light-emitting cavity with a clip. The lens cover comprises a lens body and a diffuser cover, improving the installation efficiency of the linear light. The inverted trapezoidal structure of the lens body expands the concentrated beam emitted from the LED chip plate to both sides, effectively reducing light spots and expanding the lighting coverage. It also allows adjustment of the light emission angle to suppress glare. Furthermore, the light transmitted through the lens body undergoes secondary adjustment via the diffuser cover, optimizing light uniformity and diffusion effects to prevent glare.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figs. 1 to 3As shown, a preferred embodiment of the present invention provides a linear light, comprising a lamp housing 1, an LED bead plate 2, and a lens cover plate 3. The lamp housing 1 has sealing end plates 4 at both ends and a light-emitting cavity 11 on its upper left and right sides. The LED bead plate 2 is installed within the light-emitting cavity 11. The lens cover plate 3 is an integral structure, comprising a lens body 31 and a diffuser cover plate 32. The lens body 31 is positioned below the diffuser cover plate 32 and has an inverted trapezoidal structure. The top two sides of the lens body 31 are provided with locking strips 311 that engage with the mounting grooves 12. The diffuser cover plate 32 covers the top surface of the light-emitting cavity 11, which is filled with a sealing compound 5. During specific assembly, before the sealing colloid 5 inside the light-emitting cavity 11 is completely cured, the lens cover plate 3 is snapped onto the top of the light-emitting cavity 11 to ensure that the sealing colloid 5 can effectively fill the gap between the lens cover plate 3 and the lamp housing 1.

[0021] This invention fills the light-emitting cavity 11 with sealing colloid 5, thus filling the gap between the lens cover plate 3 and the lamp housing 1. At the same time, the sealing colloid 5 covers the lamp bead plate 2, ensuring high overall sealing performance of the linear light. The lens cover plate 3 is fastened to the light-emitting cavity 11 by a clip 311. The lens cover plate 3 has a lens body 31 and a diffuser cover 32, improving the installation efficiency of the linear light. The inverted trapezoidal structure of the lens body 31 expands the concentrated beam emitted by the lamp bead plate 2 to both sides, thereby effectively reducing the light spot and expanding the lighting coverage. It can also adjust the light emission angle to suppress glare. At the same time, the light transmitted through the lens body 31 is further adjusted by the diffuser cover 32 to optimize the light uniformity and diffusion effect, avoiding glare.

[0022] For example, the thickness of the lens body 31 is greater than half the depth of the light-emitting cavity 11, which enhances the lighting effect and reduces light loss.

[0023] For example, the diffusion cover 32 is a milky white diffusion cover 32. Furthermore, the top surface of the diffusion cover 32 is a frosted surface, which makes the light output softer and more uniform, and avoids direct glare.

[0024] For example, a guide arc surface 312 is provided between the outer side of the clip 311 and the lens body 31. The cross-sectional area of ​​the clip 311 is smaller than the cross-sectional area of ​​the mounting groove 12, which makes it easier for the clip 311 of the lens cover plate 3 to be fitted into the mounting groove 12, and allows the sealing adhesive 5 to better fill the gap between the clip 311 and the mounting groove 12, ensuring a good sealing effect.

[0025] Specifically, the bottom of the lamp housing 1 is provided with a wire placement cavity 13, which facilitates the placement of components such as the power cord of the linear light in the wire placement cavity 13, avoids the power cord being exposed, and improves the aesthetics of the linear light.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
