Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a low-position lighting lamp. Background Technology

[0002] Tunnel lighting is a crucial element in ensuring driving safety. In recent years, low-mounted lights have been widely used in tunnel lighting. Typically, low-mounted lights are installed near the ground level on the tunnel walls. Therefore, to meet tunnel lighting requirements, these lights must have sufficiently intense upward-facing light. However, high-intensity upward-facing light is prone to glare. To solve the glare problem, using structural components to block the upward-facing light from the light source assembly would significantly reduce the luminous efficacy of the light source assembly, thus failing to meet tunnel lighting requirements. Utility Model Content

[0003] The main purpose of this utility model is to provide a low-position lighting lamp that aims to solve the glare problem while improving the luminous efficiency of the light source components, thereby meeting the requirements of tunnel lighting.

[0004] To achieve the above objectives, the present invention proposes a low-level lighting lamp, comprising: a light source assembly and a housing, wherein the light source assembly is disposed within the housing, and the housing has a first light-emitting surface and a second light-emitting surface, the first light-emitting surface and the second light-emitting surface being disposed facing the light source assembly, and light emitted by the light source assembly being emitted from the first light-emitting surface and the second light-emitting surface, the first light-emitting surface being disposed above the second light-emitting surface, and the first light-emitting surface having a frosted area, so that the upward light emitted by the light source assembly is emitted through the frosted area.

[0005] Optionally, the light source assembly includes a light source and a lens, the light source being installed inside the housing, and the lens covering the light source so that the light emitted by the light source passes through the lens and is emitted.

[0006] Optionally, the light source assembly includes a plurality of light sources and a plurality of lenses, with the plurality of light sources arranged side by side on the housing, and each lens covering one of the light sources, so that the light emitted by the plurality of light sources passes through the plurality of lenses respectively.

[0007] Optionally, the lens has an arc-shaped light-incident surface and an arc-shaped light-outcident surface arranged opposite to each other, and the light source is arranged relative to the arc-shaped light-incident surface so that the light from the light source enters through the arc-shaped light-incident surface and exits through the arc-shaped light-outcident surface.

[0008] Optionally, the arc-shaped light-emitting surface is recessed relative to the arc-shaped light-incident surface in a direction closer to the second light-emitting surface, in order to adjust the light emitted through the lens.

[0009] Optionally, both the arc-shaped light-incident surface and the arc-shaped light-exit surface are smooth surfaces.

[0010] Optionally, the mounting surface of the light source assembly is disposed opposite to the first light-emitting surface, and the second light-emitting surface is inclinedly disposed between the mounting surface of the light source assembly and the first light-emitting surface, so that light is emitted from the second light-emitting surface.

[0011] Optionally, the mounting surface of the light source assembly is set at an angle to the second light-emitting surface, and the angle between the mounting surface of the light source assembly and the second light-emitting surface is 45° to 60°.

[0012] Optionally, the cover includes a structural component, a light-transmitting plate, and a frosted plate. The light source assembly is disposed in the enclosed space of the structural component. The structural component has two mounting openings on adjacent side walls facing the light source assembly. The frosted plate has the frosted area. The frosted plate and the light-transmitting plate are respectively disposed in the two mounting openings to form the first light-emitting surface and the second light-emitting surface.

[0013] Optionally, the frosted area is located on the surface of the frosted plate facing the light source assembly, so that light rays incident on the frosted area are emitted through the frosted plate.

[0014] The technical solution of this utility model, when applied to tunnel lighting, involves a light source component housed within a housing. The housing has a first light-emitting surface and a second light-emitting surface, both facing the light source component. Light emitted from the light source component exits through both the first and second light-emitting surfaces. The first light-emitting surface is positioned above the second light-emitting surface. Part of the light passes through the first light-emitting surface and illuminates the tunnel wall, while part passes through the second light-emitting surface and illuminates the tunnel surface, thus achieving lighting for both the tunnel wall and the road surface. In this way, the light emitted from the light source component towards the first light-emitting surface forms upward-firing light. The first light-emitting surface has a frosted area, through which the upward-firing light is emitted. This upward-firing light undergoes diffuse reflection on the surface of the frosted area, spreading in all directions. This transforms the high-intensity upward-firing light into uniform, soft light, illuminating the tunnel space. This solves the glare problem while improving the luminous efficiency of the light source component, meeting the requirements of tunnel lighting. Attached Figure Description

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.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] See Figures 1 to 4 As shown, in one embodiment of this utility model, a low-level lighting lamp 1000 includes: a light source assembly 100 and a cover 300. The light source assembly 100 is disposed inside the cover 300. The cover 300 has a first light-emitting surface 301 and a second light-emitting surface 302. The first light-emitting surface 301 and the second light-emitting surface 302 are disposed facing the light source assembly 100. The light emitted by the light source assembly 100 is emitted from the first light-emitting surface 301 and the second light-emitting surface 302. The first light-emitting surface 301 is disposed above the second light-emitting surface 302. The first light-emitting surface 301 has a frosted area 301a so that the upward light emitted by the light source assembly 100 is emitted through the frosted area 301a.

[0026] When applied to tunnel lighting, the technical solution of this utility model has a light source assembly 100 housed inside a cover 300. The cover 300 has a first light-emitting surface 301 and a second light-emitting surface 302. The first light-emitting surface 301 and the second light-emitting surface 302 face the light source assembly 100. The light emitted by the light source assembly 100 passes through the first light-emitting surface 301 and the second light-emitting surface 302 and is emitted. The first light-emitting surface 301 is located above the second light-emitting surface 302. Some of the light passes through the first light-emitting surface 301 and illuminates the tunnel wall, while some of the light passes through the second light-emitting surface 302 and illuminates the tunnel road surface, thereby achieving lighting for both the tunnel wall and the road surface. In this way, the light emitted by the light source component 100 toward the first light-emitting surface 301 forms upward light. The first light-emitting surface 301 has a frosted area 301a. The upward light is emitted through the frosted area 301a. Thus, the upward light undergoes diffuse reflection on the surface of the frosted area 301a and diffuses in all directions. In this way, the high-intensity upward light is transformed into uniform soft light. The uniform soft light illuminates the tunnel space, thereby solving the glare problem and improving the luminous efficiency of the light source component 100, thus meeting the tunnel lighting requirements.

[0027] It should be noted that when applied to tunnel lighting, the cover 300 has two adjacent side walls. The first light-emitting surface 301 and the second light-emitting surface 302 are respectively disposed on the two adjacent side walls of the cover 300. The light emitted by the light source assembly 100 is emitted through the first light-emitting surface 301 and the second light-emitting surface 302. The first light-emitting surface 301 is disposed above the second light-emitting surface 302. The upward light and downward light are defined according to the direction of light illumination. The light emitted by the light source assembly 100 towards the first light-emitting surface 301 forms the upward light, and the light emitted by the light source assembly 100 towards the second light-emitting surface 302 forms the downward light. In order to ensure that the upward light and downward light are effectively emitted from the first light-emitting surface 301 and the second light-emitting surface 302, the tilt angle of the second light-emitting surface 302 relative to the first light-emitting surface 301 can be adjusted in this embodiment. In addition, the frosted area 301a in this embodiment can be located inside the cover 300 or outside the cover 300, as long as it can convert the high-intensity upward light into uniform soft light. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model.

[0028] See Figures 1 to 4As shown, in one embodiment of the present invention, the light source assembly 100 includes a light source 110 and a lens 130. The light source 110 is installed inside the cover 300, and the lens 130 covers the light source 100 so that the light emitted by the light source 100 passes through the lens 130 and is emitted. It should be noted that the lens 130 in this embodiment is a structure formed of light-transmitting material. The light emitted by the light source 100 passes through the lens 130 and is emitted. The lens 130 effectively controls the distribution and intensity of the light, thereby forming a certain proportion of upward and downward light. Of course, in this embodiment, the installation position of the lens 130 can be adjusted, and the specifications and shape of the lens 130 can also be adjusted to achieve the ratio control of upward and downward light. In this embodiment, the substrate 200 is disposed inside the cover 300, the light source 110 is mounted on the substrate 200, and the lens 130 is movably mounted on the substrate 200 and covers the light source 110. The movable mounting method can be a detachable connection, a sliding connection, or a rotating connection, etc., as long as the lens 130 covers the light source 100 to form a certain proportion of upward and downward light. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. In this embodiment, the light emitted by the light source 100 is formed into a certain proportion of upward and downward light through the lens 130. In this way, the upward and downward light are emitted through the first light-emitting surface 301 and the second light-emitting surface 302, thereby converting the high-intensity upward light into uniform soft light, thus meeting the tunnel lighting requirements.

[0029] See Figures 1 to 4 As shown, in one embodiment of this utility model, the light source assembly 100 includes multiple light sources 110 and multiple lenses 130. The multiple light sources 100 are arranged side by side on the cover 300, and each lens 130 covers one light source 100, so that the light emitted by the multiple light sources 100 is emitted through the multiple lenses 130 respectively. It should be noted that in this embodiment, the multiple light sources 100 are arranged side by side on the substrate 200, and each light source 100 is covered by a lens 130. The multiple lenses 130 cover the multiple light sources 100 respectively, so that the light from the multiple light sources 100 is emitted through the multiple lenses 130 respectively, thereby forming a uniform soft light of a certain brightness, thus meeting the tunnel lighting requirements. Specifically, in this embodiment, the number of light sources 100 can be set according to the actual needs of the tunnel. In this embodiment, six spaced light sources 100 are provided on the substrate 200, and the low-level lighting lamp 1000 realizes tunnel lighting through the six light sources 100. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model.

[0030] See Figures 1 to 4As shown, in one embodiment of this utility model, the lens 130 has an arc-shaped light-incident surface 131 and an arc-shaped light-exit surface 133 arranged opposite to each other. The light source 100 is positioned relative to the arc-shaped light-incident surface 131, so that the light from the light source 100 enters through the arc-shaped light-incident surface 131 and exits through the arc-shaped light-exit surface 133. In this embodiment, the light from the light source 100 enters the lens 130 through the arc-shaped light-incident surface 131 and exits through the arc-shaped light-exit surface 133, thereby adjusting the direction of light propagation. As a result, the light diverges into a certain proportion of upward and downward light, which is beneficial for forming uniform soft light after passing through the first light-exit surface 301 and the second light-exit surface 302, thus ensuring the brightness of the uniform soft light and meeting the requirements of tunnel lighting.

[0031] See Figures 1 to 4 As shown, in one embodiment of this utility model, the arc-shaped light-emitting surface 133 is recessed relative to the arc-shaped light-incident surface 131 towards the second light-emitting surface 302, in order to adjust the light emitted through the lens 130. It should be noted that this embodiment, by recessing the arc-shaped light-emitting surface 133 relative to the arc-shaped light-incident surface 131 towards the second light-emitting surface 302, adjusts the ratio of upward and downward light, thereby ensuring road surface illumination while meeting the wall illumination requirements, thus achieving illumination of the tunnel space and satisfying tunnel lighting requirements.

[0032] See Figures 1 to 4 As shown, in one embodiment of this utility model, both the arc-shaped light-incident surface 131 and the arc-shaped light-exit surface 133 are smooth surfaces. It should be noted that in this embodiment, both the arc-shaped light-incident surface 131 and the arc-shaped light-exit surface 133 are smooth surfaces, thereby preventing diffuse reflection of the incident light on the surface of the lens 130, thus ensuring the intensity of the emitted upward and downward light. In this way, the upward and downward light of a certain intensity pass through the first light-exit surface 301 and the second light-exit surface 302 respectively, forming a uniform soft light of a certain brightness, thereby meeting the lighting requirements of the tunnel while avoiding glare.

[0033] See Figures 1 to 4As shown, in one embodiment of this utility model, the mounting surface of the light source assembly 100 is disposed opposite to the first light-emitting surface 301, and the second light-emitting surface 302 is inclinedly disposed between the mounting surface of the light source assembly 100 and the first light-emitting surface 301, so that the light emitted by the light source assembly 100 passes through the second light-emitting surface 302 and is emitted. It should be noted that in this embodiment, the light source assembly 100 faces the first light-emitting surface 301 and the second light-emitting surface 302, and the upward and downward light emitted by the light source assembly 100 passes through the first light-emitting surface 301 and the second light-emitting surface 302 respectively, thereby achieving illumination of the tunnel space. Preferably, in this embodiment, the mounting surface of the light source assembly 100 and the second light-emitting surface 302 are arranged at an angle, and the angle between the mounting surface of the light source assembly 100 and the second light-emitting surface 302 is θ, i.e., θ = 45° to 60°. This implementation adjusts the tilt angle of the second light-emitting surface 302 so that the downward-facing light passes through the second light-emitting surface 302, thereby increasing the transmittance of the downward-facing light, ensuring the lighting effect on the road surface, and meeting the brightness requirements of road lighting.

[0034] See Figures 1 to 4 As shown, in one embodiment of this utility model, the cover 300 includes a structural member 310, a light-transmitting plate 330, and a frosted plate 320. The light source assembly 100 is disposed in the space enclosed by the structural member 310. The structural member 310 has two mounting openings on its adjacent side walls facing the light source assembly 100. The frosted plate 320 has a frosted area 301a. The frosted plate 320 and the light-transmitting plate 330 are respectively disposed in the two mounting openings to form a first light-emitting surface 301 and a second light-emitting surface 302. It should be noted that in this embodiment, the structural member 310 forms an enclosing space. The light source assembly 100 is installed in the enclosing space of the structural member 310 through the substrate 200. The structural member 310 is fixed to the tunnel wall, and the structural member 310 provides the necessary strength support for the installation of the light source assembly 100. In this embodiment, the thickness of the frosted plate 320 and the light-transmitting plate 330 can be adjusted according to the implementation situation, so that the light source point of the light source assembly 100 is not visible. Of course, both the frosted plate 320 and the light-transmitting plate 330 are made of light-transmitting material, which can be glass, polycarbonate (PC), or other transparent materials. This embodiment is not limited to these, and all of the above are within the protection scope of this utility model. In this embodiment, the structural component 310 has two mounting openings on the two side walls facing the light source assembly 100. The frosted plate 320 has a frosted area 301a. The frosted plate 320 is located in the upper mounting opening to form a first light-emitting surface 301, and the light-transmitting plate 330 is located in the lower mounting opening to form a second light-emitting surface 302. In this way, the light emitted by the light source assembly 100 passes through the frosted plate 320 and the light-transmitting plate 330 and is emitted, thereby forming uniform and soft light. This avoids glare problems and improves the light efficiency of the light source assembly 100, meeting the requirements of tunnel lighting.

[0035] See Figures 1 to 4As shown, in one embodiment of this utility model, a frosted area 301a is disposed on the surface of the frosted plate 320 facing the light source assembly 100, so that light incident from the frosted area 301a passes through the frosted plate 320 and is emitted. It should be noted that, in this embodiment, the surface of the frosted plate 320 facing the light source assembly 100 can be formed by a white coating process to create the frosted area 301a. The white powder in the frosted area 301a effectively diffuses the upward-injected light, thereby converting the high-intensity upward-injected light into uniform soft light. In this way, the emitted uniform soft light illuminates the tunnel, ensuring a stable lighting effect for the tunnel and thus meeting the tunnel lighting requirements.

[0036] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
