[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] This application discloses a lamp fixture; please refer to [link / reference]. Figure 1 and Figure 2 The device includes a housing 100, a photomask 200, and a first lamp plate 300. The housing 100 includes a housing portion 110 and a base plate portion 120 connected together. The base plate portion 120 is provided with a light outlet 121. The photomask 200 is arc-shaped and disposed inside the housing portion 110, and is at least partially disposed facing the light outlet 121. The first lamp plate 300 is disposed inside the base plate portion 120, and the side of the first lamp plate 300 with lamp beads is disposed facing the photomask 200. The photomask 200 is used to receive the light emitted by the first lamp plate 300 and to propagate the light towards the light outlet 121.

[0031] In practical applications, the illumination light emitted by the first lamp panel 300 shines onto the photomask 200, which is arc-shaped. Therefore, the photomask 200 receives and processes the illumination light, causing it to be emitted from the light outlet 121. It is understood that by arranging the photomask 200 and the first lamp panel 300 in the aforementioned positions, they can be compactly fitted inside the housing 110, thus fully utilizing the internal space of the housing 110 and reducing assembly difficulty. Simultaneously, the utilization rate of the light path is improved; the illumination light emitted by the first lamp panel 300 does not need to pass through a complex reflection path, and most of the light can be directly converged to the light outlet 121 through the photomask 200, reducing scattering, absorption, or leakage of light in unnecessary paths.

[0032] Furthermore, the light emitted from the first lamp panel 300 is not directly emitted through the light outlet 121. Instead, the light emitted from the first lamp panel 300 is focused by the light cover 200, and the illumination light is controlled to be emitted from the light outlet 121 at a set angle. This configuration effectively reduces the glare emitted by the illumination light. In order to control the angle of the illumination light, the posture of the light cover can be controlled, thereby controlling the angle of the illumination light and achieving the effect of reducing glare.

[0033] In some embodiments, please refer to Figure 1 and Figure 2 Along the width direction of the light cover 200, the light cover 200 is divided into a first arc-shaped portion 210 and a second arc-shaped portion 220. The curvature of the first arc-shaped portion 210 is greater than that of the second arc-shaped portion 220, or in other words, along the height direction of the lamp, the slope of the first arc-shaped portion 210 is greater than that of the second arc-shaped portion 220. The first arc-shaped portion 210 is positioned towards the first lamp panel 300, and the second arc-shaped portion 220 is positioned towards the light outlet 121. It is understood that the curvature of the first arc-shaped portion 210 is sufficiently large, allowing it to receive the illumination light emitted from the first lamp panel 300 and propagate the illumination light towards the light outlet 121. Similarly, the second arc-shaped portion 220 can also receive the illumination light emitted from the first lamp panel 300 and propagate the illumination light towards the light outlet 121.

[0034] Further, please refer to Figure 2 and Figure 3 The luminaire also includes a grille 400 disposed at the light outlet 121. The grille 400 includes multiple grille plates 420, which are arranged sequentially at intervals along the length of the light outlet 121, forming a grille opening between adjacent grille plates 420. It is understood that the grille plates 420 allow for precise light control and optimization of the lighting range and direction. 1. Limiting glare and stray light: The grid structure of the grille plates 420 (usually parallel or intersecting strips or mesh) can block scattered light rays deviating from the main lighting direction in the direct light from the light source, achieving the effect of cutting off light from both sides. This reduces the diffusion of light to non-target areas, especially in high-brightness luminaires (such as office chandeliers and shopping mall spotlights), preventing glare caused by direct light hitting the eyes and improving visual comfort. 2. Focused Lighting Area: By designing the angle of the grid (such as a narrow-angle grid), light can be concentrated in a specific area (such as a desktop, display case, or workbench), reducing ineffective lighting of the surrounding environment and improving light efficiency. This is suitable for scenarios requiring precise lighting (such as laboratories and exhibition halls). 3. Adjustable Light Diffusion Angle: Grids of different densities or angles can control the range of light diffusion. For example, dense grids are suitable for small-area focused lighting, while sparse grids are suitable for medium-range uniform lighting, meeting diverse lighting needs.

[0035] Further, please refer to Figure 2 and Figure 3The grille member 400 further includes two connecting plates 410. A plurality of grille plates 420 are sequentially connected between the two connecting plates 410 along the length of the connecting plates 410. The grille plates 420 are perpendicular to the connecting plates 410, and the two connecting plates 410 are respectively connected to opposite sides of the light outlet 121. Specifically, the inner side of the base plate 120 is provided with two L-shaped retaining portions 130, located on both sides of the light outlet 121. Each retaining member forms a slot 131 with the base plate 120, and the two slots 131 are arranged opposite each other. The sidewall of the slot 131 is provided with an arc-shaped protrusion 140 to abut against the side of the connecting plate 410.

[0036] Specifically, when the grille 400 is installed on the base plate 120, one connecting plate 410 is inserted into a slot 131, and the arc-shaped protrusion 140 abuts against the side wall of the connecting plate 410; another connecting plate 410 is inserted into another slot 131, and the arc-shaped protrusion 140 abuts against the side wall of the other connecting plate 410, thereby allowing the grille 400 to be easily installed at the light outlet 121. The arc-shaped protrusion 140 and the side wall of the connecting plate 410 can be securely abutted, allowing the connecting plate 410 to be firmly inserted into the slot 131, thus ensuring the grille 400 is securely installed at the light outlet 121.

[0037] In some embodiments, please refer to Figure 2 and Figure 3 Each of the connecting plates 410 has an elastic arm 430 on its inner side, which is perpendicular to the connecting plate 410. The end of each elastic arm 430 has a protruding locking portion 440, with the protrusion of the locking portion 440 facing inwards towards the light outlet 121. The lamp also includes a first light-transmitting plate, which is disposed at the light outlet 121, with its edge abutting between the connecting plate 410 and the locking portion 440.

[0038] During lamp assembly, the first light-transmitting plate and the grille 400 can be installed together. The first light-transmitting plate is installed on the inner side of the connecting plate 410, and the two long edges of the first light-transmitting plate abut against the connecting plate 410 and the locking part 440 respectively, thereby assembling the first light-transmitting plate and the grille 400 together. In this way, when the grille 400 is assembled at the light outlet 121, the first light-transmitting plate is also assembled at the light outlet 121, thus facilitating the assembly of the lamp.

[0039] In some embodiments, the light cover 200 is configured as a reflector or a lens. If the light cover 200 is configured as a reflector, after receiving the illumination light emitted by the first lamp panel 300, the reflector will reflect the received illumination light to the light outlet 121; if the light cover 200 is configured as a lens, after the illumination light enters the lens, the illumination light is reflected back inside the lens, which depends on the curved surface design of the lens and the control of the light incident angle, so that the illumination light is emitted from the light outlet 121.

[0040] In some embodiments, please refer to Figure 1 and Figure 2 The photomask 200 has flanges 230 on both sides, and the inner walls of the outer shell 110 have slots 111 on opposite sides. For example, the inner walls of the outer shell 110 have ribs, and slots 111 can be formed between two ribs. The two flanges 230 are respectively inserted into the slots 111. It can be understood that with the above-described structure, the photomask 200 can be easily assembled onto the inner side of the outer shell 110 via the flanges 230.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 The lamp further includes a second lamp plate 600 and a second light-transmitting plate 700. A groove 112 is provided on the top of the outer casing 110. The second lamp plate 600 is disposed in the groove 112, and the second light-transmitting plate 700 is disposed in the opening of the groove 112. In practical applications, the second lamp plate 600 emits illumination light outward through the second light-transmitting plate 700, thereby illuminating the top of the lamp.

[0042] It should be noted that the first lamp panel 300 is set on the base plate 120. This arrangement saves enough space on the inside of the outer shell 110, and the top of the outer shell 110 can be recessed into a sufficiently large groove 112 for installing the second lamp panel 600, effectively avoiding the need for the lamp to be made in a larger size.

[0043] In some embodiments, please refer to Figure 1 and Figure 4The lamp fixture also includes a support column 800 and a clamping assembly 900. The clamping assembly 900 is connected to the bottom of the support column 800, and the outer shell 100 is connected to the top of the support column 800. The clamping assembly 900 can be used to clamp onto the edge of a tabletop. Specifically, the clamping assembly 900 includes a U-shaped plate 910, an adjusting rod 920, and a clamping plate 930. The bottom of the support column 800 is vertically connected to one side plate of the U-shaped plate 910, the adjusting rod 920 is threaded to the other side plate of the U-shaped plate 910, and the clamping plate 930 is located inside the U-shaped plate 910 and connected to the adjusting rod 920. Therefore, when the lamp fixture is installed on the tabletop, the edge of the lamp plate is engaged within the U-shaped plate 910. By controlling the adjusting rod 920, the clamping plate 930 is securely held against the underside of the tabletop, thereby securing the clamping assembly 900 firmly to the edge of the tabletop for easy use.
