Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a linear lamp. Background Art

[0002] Lamps are a general term for lighting tools, which are divided into chandeliers, table lamps, wall lamps, floor lamps, etc. It refers to an appliance that can transmit light, distribute and change the light distribution of a light source, including all parts required to fix and protect the light source except the light source, as well as the line accessories necessary for connecting to the power supply.

[0003] In the related art, the lamp is composed of a light source module and a lampshade. The light source module is housed in the lampshade and emits light through the lampshade to achieve the lighting effect. Since the stability of the light source needs to be ensured, the light source module is usually fixedly connected to the lampshade. However, this setting method cannot adjust the distance between the light source module and the lampshade, that is, it is impossible to adjust the light intensity according to the different lighting intensity requirements of different areas under the condition of the same power.

[0004] Therefore, the technical problem to be solved by the present invention is to provide a lamp which can adjust the distance between the light source module and the lampshade while ensuring the stability of the light source. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides a linear lamp, which solves the problem that the light intensity cannot be adjusted according to different lighting intensity requirements of different areas under the condition of the same power.

[0006] The technical effect to be achieved by the utility model is achieved through the following technical solutions:

[0007] The utility model provides a linear lamp, comprising:

[0008] A housing having a light emitting surface;

[0009] A light-emitting cover, disposed on the light-emitting surface;

[0010] A light source assembly is housed in the housing; and

[0011] The connecting piece is respectively connected to the inner wall of the shell and the light source assembly, so that the light source assembly is fixed in the shell and does not directly contact the shell.

[0012] In some implementations, the connecting member includes a first supporting surface, a second supporting surface and a connecting surface, the first supporting surface and the second supporting surface are respectively connected to the inner wall of the housing, and both ends of the connecting surface are respectively connected to the first supporting surface and the second supporting surface at one end away from the inner wall of the housing, and are connected to the light source assembly;

[0013] The first supporting surface, the second supporting surface and the connecting surface together form a frame-shaped body to fix the light source assembly.

[0014] In this implementation, the first supporting surface and the second supporting surface have the same length, are arranged in parallel and spaced apart, and the two ends are respectively connected to the inner wall and the connecting surface of the shell, and the connecting surface is fitly connected to the light source assembly. The first supporting surface and the second supporting surface are arranged in parallel between the shell and the light source assembly, which has a stronger supporting effect on the light source assembly and ensures the reliability of the light source illumination angle.

[0015] In some implementations, a connecting portion that fits against the inner wall of the shell extends from one end of the connecting member connected to the inner wall of the shell.

[0016] In this implementation, the connection portion increases the connection area between the connection piece and the inner wall of the shell, thereby making the connection between the connection piece and the shell more stable, and further making the connection between the shell and the light source assembly more secure.

[0017] In some implementations, the light source assembly includes a focusing piece and an LED light group disposed on the focusing piece; the focusing piece includes a first focusing surface, a second focusing surface and a mounting surface, the mounting surface is connected to the LED light group, the first focusing surface and the second focusing surface are respectively connected to the two ends of the mounting surface and extend toward the direction of the light output cover.

[0018] In this implementation, the focusing element allows the light emitted by the LED lamp group to shine on the light output cover. When the LED lamp group starts working and emits light in all directions, under the action of the first focusing surface and the second focusing surface, the light is gathered and irradiated in the direction of the light output cover, thereby making the lighting effect more superior.

[0019] In some implementations, the first light-focusing surface and the second light-focusing surface are arranged to be inclined relative to each other.

[0020] In some implementations, the shell is a U-shaped body formed by bending a metal sheet.

[0021] In this implementation, the wall thickness of the shell is made thinner, thereby reducing the overall weight of the lamp, making it easier to install or disassemble, and further improving the reliability of the overall structure.

[0022] In some implementations, a connection between the housing and the light output cover is bent inward to form a slot, and two ends of the light output cover are formed with blocks for being engaged in the slot.

[0023] In some implementations, an inner surface of the light output cover has a Fresnel texture.

[0024] In this implementation, when light passes through the Fresnel texture, it bends, thereby generating a diffraction phenomenon, so that the light output cover has a real image magnification function similar to a convex lens, further enhancing the brightness of the light and providing a more superior lighting effect.

[0025] In some implementations, the linear lamp further includes a mounting portion connected to an outer wall of the housing.

[0026] In some implementations, mounting holes are respectively opened on both sides of the shell, and both end portions of the mounting portion are respectively bent to form bending angles for snapping into the mounting holes.

[0027] In this implementation, the bent corner is snapped into the mounting hole so that the mounting portion is snapped into the shell, thereby achieving a stable connection between the shell and the mounting portion while facilitating disassembly.

[0028] In summary, the utility model has at least the following benefits:

[0029] The linear lamp provided by the utility model has a light source assembly connected to the inner wall of the housing through a connecting piece and does not directly contact the housing, so that the distance between the light source assembly and the light output cover can be adjusted by adjusting the length of the connecting piece, that is, adjusting the length of the connecting piece can make the light source assembly close to and / or away from the light output cover, so that the same power lamp can achieve different lighting intensities. Under the premise of ensuring the stability of the light source, the problem of being unable to adjust the light intensity according to the different lighting intensity requirements of different areas under the condition of the same power is solved.

[0043] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] Please see attached Figures 1 to 4 The linear lamp of the utility model comprises a housing 1, a light output cover 2, a light source assembly 3 and a connecting piece 4.

[0047] Please combine Figure 1 and Figure 2 , Figure 1 The structure relationship between the housing 1 and the light output cover 2 in the embodiment of the utility model is shown in FIG. Figure 2The schematic diagram shows the structural relationship between the housing 1, the light emitting cover 2, the connecting member 4 and the light source assembly 3 in the embodiment of the utility model. Specifically, the housing 1 has a light emitting surface 11; the light emitting cover 2 is disposed on the light emitting surface 11; the light source assembly 3 is accommodated in the housing 1; the connecting member 4 is respectively connected to the inner wall of the housing 1 and the light source assembly 3, so that the light source assembly 3 is fixed in the housing 1 and does not directly contact the housing 1.

[0048] In this embodiment, the light hood 2 is covered on the light emitting surface 11 of the housing 1, and the light source assembly 3 emits light through the light emitting surface 11 to achieve the lighting effect; since the light source assembly 3 is connected to the inner wall of the housing 1 through the connecting member 4, the distance of the light source assembly 3 relative to the light hood 2 can be adjusted by adjusting the length of the connecting member 4, so that the light source assembly 3 can be close to and / or away from the light hood 2, and then the lighting intensity of the lamp can be enhanced and / or reduced under the same lamp power, which is further more suitable for different lighting scenes. It can be understood that due to different lighting requirements in different places, in order to ensure the detachability of the connecting member 4 relative to the housing 1 and / or the light source assembly 3, the connecting member 4 can be connected to the housing 1 and the light source assembly 3 respectively by screwing or clamping. In the embodiment of the utility model, the connecting member 4 is screwed to the housing 1 and the light source assembly 3 respectively by screws, which ensures the detachability and the connection stability. At the same time, different numbers of connecting members 4 can be set according to the length of the linear lamp to ensure the connection stability between the housing 1 and the light source assembly 3.

[0049] In the above linear lamp, since the light source assembly 3 is connected to the inner wall of the housing 1 through the connecting piece 4 and does not directly contact the housing 1, the distance between the light source assembly 3 and the light output cover 2 can be adjusted by adjusting the length of the connecting piece 4, that is, by adjusting the length of the connecting piece 4, the light source assembly 3 can be moved closer to and / or farther from the light output cover 2, so that the same power lamp can achieve different lighting intensities. Under the premise of ensuring the stability of the light source, the problem of not being able to adjust the light intensity according to the different lighting intensity requirements of different areas under the condition of the same power is solved.

[0050] In some preferred embodiments, see Figure 3 , Figure 3 The specific structure of the connector 4 in the embodiment of the utility model is illustrated. Specifically, the connector 4 includes a first supporting surface 41, a second supporting surface 42 and a connecting surface 43. The first supporting surface 41 and the second supporting surface 42 are respectively connected to the inner wall of the housing 1. The two ends of the connecting surface 43 are respectively connected to the first supporting surface 41 and the second supporting surface 42 away from the inner wall of the housing 1, and connected to the light source assembly 3; the first supporting surface 41, the second supporting surface 42 and the connecting surface 43 together form a frame body to fix the light source assembly 3.

[0051] In this embodiment, the first support surface 41 and the second support surface 42 are of the same length, and are arranged in parallel and spaced apart, with the two ends connected to the inner wall of the housing 1 and the connecting surface 43 respectively, and the connecting surface 43 is connected to the light source assembly 3 in a close fit, and the first support surface 41 and the second support surface 42 make the housing 1 and the light source assembly 3 arranged in parallel, which has a stronger support effect on the light source assembly 3, and ensures the reliability of the light source irradiation angle, making the connection between the housing 1 and the light source assembly 3 more secure, further ensuring the stability of the light source, and avoiding the problem that the light source assembly 3 is tilted at an irradiation angle and cannot fully irradiate the light cover 2, thus affecting the lighting effect. Preferably, the first support surface 41 and the second support surface 42 are respectively connected to the top wall of the housing 1, so that when the housing 1 is installed on the ceiling, the first support surface 41 and the second support surface 42 respectively have a better support effect on the light source assembly 3.

[0052] In some more preferred embodiments, see Figure 4 , Figure 4 The structural relationship between the connecting portion 44 and the housing 1 in the embodiment of the utility model is illustrated. Specifically, a connecting portion 44 that fits the inner wall of the housing 1 is extended from one end of the connecting member 4 connected to the inner wall of the housing 1. The connecting portion 44 increases the area of ​​the connecting surface 43 between the connecting member 4 and the inner wall of the housing 1, thereby making the connection between the connecting member 4 and the housing 1 more stable, and further making the connection between the housing 1 and the light source assembly 3 more secure. It can be understood that in order to ensure the connection reliability of the overall structure, in this embodiment, the first supporting surface 41 and the second supporting surface 42 are respectively extended with a connecting portion 44 that fits the inner wall of the housing 1 at the connection points with the inner wall of the housing 1.

[0053] Embodiment 2:

[0054] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the linear lamp of the utility model. Figures 5 and 6 .

[0055] Among them, see Figure 5 , Figure 5 The specific structure of the light source assembly 3 in the embodiment of the utility model is illustrated. Specifically, the light source assembly 3 includes a light collecting member 31 and an LED light group 32 arranged on the light collecting member 31; the light collecting member 31 includes a first light collecting surface 311, a second light collecting surface 312 and a mounting surface 313, the mounting surface 313 is connected to the LED light group 32, and the first light collecting surface 311 and the second light collecting surface 312 are respectively connected to the two ends of the mounting surface 313 and extend toward the direction of the light output cover 2.

[0056] In this embodiment, the light collecting member 31 allows the light emitted by the LED lamp group 32 to irradiate the light output cover 2. When the LED lamp group 32 starts to work and emits light to the surroundings, the light is gathered and irradiated in the direction of the light output cover 2 under the action of the first light collecting surface 311 and the second light collecting surface 312, thereby achieving a better lighting effect. It can be understood that under the same power, the lighting effect of the lamp with the light collecting member 31 is better than that of the lamp without the light collecting member 31, thereby saving energy consumption of the lamp.

[0057] In some preferred embodiments, the first light focusing surface 311 and the second light focusing surface 312 are relatively inclined. The first light focusing surface 311 and the second light focusing surface 312 are respectively inclined toward the connection between the housing 1 and the light output cover 2, so that the illumination angle of the LED light group 32 is distributed from narrow to wide in a trapezoidal shape. In order to make the lighting effect of the LED light group 32 better, in this embodiment, see Figure 6 , Figure 6 The structure relationship between the Fresnel texture 22 and the light output cover 2 in the embodiment of the utility model is illustrated. Specifically, the inner surface of the light output cover 2 is provided with the Fresnel texture 22. When the light passes through the Fresnel texture 22, it will bend, thereby generating a diffraction phenomenon, so that the light output cover 2 has a real image magnification function similar to a convex lens, further improving the brightness of the light and achieving a better lighting effect.

[0058] In some preferred embodiments, the housing 1 is a U-shaped body formed by bending a metal sheet. This makes the wall thickness of the housing 1 thinner, thereby reducing the overall weight of the lamp, making it easier to install or disassemble, and further improving the reliability of the overall structure. Preferably, the metal sheet can be a bendable sheet-like object such as a steel sheet, an aluminum sheet, and a copper sheet. In this embodiment, the metal sheet is a steel sheet.

[0059] In some preferred embodiments, see Figure 6 , Figure 6 The structural relationship between the card slot 12 and the card block 21 in the embodiment of the utility model is illustrated. Specifically, the connection between the shell 1 and the light output cover 2 is bent inward to form a card slot 12, and the two ends of the light output cover 2 are formed with card blocks 21 for being snapped into the card slot 12. The card block 21 is snapped into the card slot 12 so that the light output cover 2 is snapped into the shell 1, which ensures the connection stability between the shell 1 and the light output cover 2 while facilitating disassembly. When the shell 1 and / or the light output cover 2 is damaged, the snapping effect between the card block 21 and the card slot 12 is released, and the shell 1 and the light output cover 2 can be separated, so as to be replaced, thereby improving the maintenance efficiency. Of course, the shell 1 and the light output cover 2 are not limited to being connected together by snapping, and can also be connected by welding, hinged or inlaying.

[0060] In some more preferred embodiments, the slot 12 has an elastic wall 121 and a fixed wall 122, and the elastic wall 121 forms a protrusion 123 in the slot; when the block 21 is inserted into the slot 12, the elastic wall 121 is first elastically avoided, and after the block 21 is inserted into the slot 12, the elastic wall 121 is reset to achieve the snap connection. The elastic wall 121 prevents the block 21 of the light output cover 2 from being worn during the process of being inserted into the slot 12, plays a role in protecting the block 21, and further prolongs the service life of the light output cover 2; moreover, the elastic wall 121 can form a more complex connection surface for the snap connection structure between the light output cover 2 and the housing 1, and has a better sealing effect.

[0061] Embodiment 3:

[0062] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the linear lamp of the utility model. Figure 7 .

[0063] Among them, see Figure 7 , Figure 7 The schematic diagram shows the structural relationship between the mounting portion 5 and the housing 1 in the embodiment of the utility model. Specifically, the linear lamp further comprises a mounting portion 5 , and the mounting portion 5 is connected to the outer wall of the housing 1 .

[0064] In this embodiment, the mounting portion 5 facilitates the installer to install the linear lamp on a wall or ceiling without affecting the internal structure of the linear lamp, thereby avoiding damage to the internal parts of the linear lamp during installation, which may lead to malfunctions. Preferably, the mounting portion 5 is arranged on the outer wall at the top of the housing 1, so that the linear lamp can be installed on the ceiling by hanging.

[0065] In some preferred embodiments, mounting holes 13 are respectively formed on both sides of the housing 1, and both ends of the mounting portion 5 are respectively bent to form bending angles 51 for clamping in the mounting holes 13. The bending angles 51 are clamped in the mounting holes 13, so that the mounting portion 5 is clamped in the housing 1, and the connection between the housing 1 and the mounting portion 5 is realized, and the disassembly is convenient. When the linear lamp is installed on the wall, the mounting portion 5 can be disassembled, and the housing 1 can be directly fixed on the wall with bolts to install the linear lamp on the wall, so as to improve the reliability of the overall structure.

[0066] In the linear lamp of the utility model, since the light source assembly 3 is connected to the inner wall of the housing 1 through the connecting piece 4 and does not directly contact the housing 1, the distance between the light source assembly 3 and the light output cover 2 can be adjusted by adjusting the length of the connecting piece 4, that is, by adjusting the length of the connecting piece 4, the light source assembly 3 can be brought close to and / or away from the light output cover 2, so that the effect of different lighting intensities can be achieved with the same power lamp. Under the premise of ensuring the stability of the light source, the problem of not being able to adjust the light intensity according to the different lighting intensity requirements of different areas under the condition of the same power is solved.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0069] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
