[0004] Existing linear lights have the following drawbacks: 1. They are mounted on commercial display cases and indoor cabinets using metal mounting clips. These clips can easily break the edges of the wooden panels inside the display cases and cabinets during installation and removal, making assembly and disassembly inconvenient. 2. Linear lights have a limited light output area and lack overall illumination. 3. The overall structure of the linear light is difficult to assemble. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a linear lamp in view of the current status of the existing technology, so as to facilitate installation and improve the light transmittance of the entire lamp.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a linear lamp, comprising: a strip-shaped lamp body and a light source, characterized in that:

[0007] The lamp body comprises a longitudinally extending top wall, a bottom wall located below the top wall, and side walls connecting the top and bottom walls. The two side walls are integrally connected to the top and bottom walls to form a light-transmitting component and together define a strip-shaped cavity. Furthermore, a soft rubber strip is integrally formed along the longitudinal direction on the outer side of the bottom wall, which is flexibly deformable under pressure to facilitate installation of the lamp body in a desired installation location.

[0008] The light source is arranged in the cavity and faces the top wall of the lamp body.

[0009] Because the side walls, top wall, and bottom wall of the lamp body are connected to form a translucent component and together define a strip-shaped cavity for the light source, the translucent component can emit light throughout, improving the overall light transmittance of the lamp. The soft rubber strip design of this utility model facilitates the installation of the linear lamp in its intended location and eliminates the edge cracking that can occur during installation and removal, unlike metal shrapnel. Furthermore, because the soft rubber strip is located on the outside of the bottom wall, it essentially does not affect the light output of the translucent component once installed in its intended location.

[0010] Preferably, there are at least two soft rubber strips, which are arranged at intervals along the transverse direction of the lamp body.

[0011] Furthermore, there are two soft rubber strips, which extend upward in opposite directions from the connection points between the corresponding bottom wall and the side wall.

[0012] Furthermore, the wall thickness of each soft rubber strip gradually decreases from bottom to top, thereby facilitating the assembly between the soft rubber strip and the location to be installed.

[0013] Preferably, the light-transmitting component is a hard plastic piece. The hard plastic piece and the soft plastic strip can be formed by integrally extruding the hard and soft plastic.

[0014] In each of the above solutions, a heat sink is preferably included, located within the cavity, below the light source, and in contact with the light source to dissipate heat generated by the light source. This can extend the lifespan of the linear light. Because the heat sink is embedded within the cavity, it is invisible to the user from the outside. Furthermore, its location below the light source does not affect its illumination.

[0015] Furthermore, the cavity is open at one end, the heat sink is strip-shaped, and longitudinally extending grooves and protrusions are provided on the side surfaces of the heat sink and the corresponding side walls of the lamp body. The grooves and protrusions engage with each other as the heat sink is inserted from the open end into the cavity, thereby facilitating assembly while ensuring that the heat sink is stably restrained within the cavity.

[0016] Furthermore, an end cover is included, which is detachably arranged at the end opening of the cavity.

[0017] Compared with the existing technology, the advantages of the present invention are: because the side walls, top wall, and bottom wall of the lamp body are connected to form a light-transmitting component and together define a strip-shaped cavity for the light source, the entire light-transmitting component can emit light, thereby improving the light transmittance of the entire lamp. In addition, the design of the soft rubber strip in the present invention facilitates the installation of the linear lamp in the desired installation location and does not cause edge cracking during installation and removal like metal shrapnel. At the same time, because the soft rubber strip is located on the outside of the bottom wall, once the soft rubber strip is installed in the desired installation location, it will basically not affect the light output of the light-transmitting component.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 FIG. 1 is a preferred embodiment of a linear lamp of the present invention. The linear lamp includes a strip-shaped lamp body 1 , a light source 2 , a heat sink 3 and an end cover 4 .

[0023] The lamp body 1 has a top wall 11 extending longitudinally, a bottom wall 12 located below the top wall 11, and side walls 13 connecting the top wall 11 and the bottom wall 12. The two side walls 13 are connected to the top wall 11 and the bottom wall 12 as a light-transmitting component, and together define a strip-shaped cavity 10, both ends of which are open. At the same time, a soft rubber strip 14 that can flexibly deform under pressure is integrally formed on the outer side of the bottom wall 12 along the longitudinal direction, so that the lamp body 1 can be installed to the location to be installed. In this embodiment, there are two soft rubber strips 14, which are arranged at intervals along the transverse direction of the lamp body 1, and the two soft rubber strips 14 extend upward and tilted in opposite directions from the corresponding connection point between the bottom wall 12 and the side wall 13, and the wall thickness of each soft rubber strip 14 gradually decreases from bottom to top.

[0024] In this embodiment, the light-transmitting component is a hard plastic component, specifically a light-diffusing frosted PC. The hard plastic component and the soft plastic strip are formed by integrally extruding the hard and soft plastics, so that the light-transmitting component and the soft plastic strip are an integrated component.

[0025] The light source 2 is a strip-shaped LED light strip, which is longitudinally inserted into the cavity 10 from the open end of the cavity 10 and faces the top wall 11 of the lamp body 1 .

[0026] The heat sink 3 is a strip of aluminum heat dissipating material. It is inserted longitudinally from the open end of the cavity 10 into the cavity 10, below the light source 2, and in contact with the light source 2 to dissipate heat generated by the light source 2. To constrain the position of the heat sink 3, longitudinally extending grooves 31 and protrusions 131 are respectively provided on the side surfaces of the heat sink 3 and the corresponding side walls 13 of the lamp body 1. The grooves 31 and protrusions 131 mate with each other as the heat sink 3 is inserted from the open end into the cavity 10, making assembly of the heat sink more convenient.

[0027] There are two end covers 4 , which are respectively inserted into the end openings of the corresponding cavities 10 to close the openings and prevent the light source and the heat sink 3 from accidentally separating from the lamp body 1 .

[0028] When assembling the linear lamp, the light source 2 and the heat sink 3 are inserted into the cavity 10 , and then the two end covers 4 are used to close the opening of the cavity 10 , which is convenient for operation.

[0029] During installation, the soft rubber strip 14 on the linear lamp of this embodiment can be inserted into the groove at the installation position, which is easy to operate. Moreover, since the soft rubber strip can be flexibly deformed after being pressed, the groove at the installation position can be avoided from being damaged during installation.

[0030] When lighting, the light generated by the light source can be emitted from the top wall 11 and the two side walls 13 of the lamp body 1, and the human eye has an overall luminous effect.

[0031] In the specification and claims of this utility model, directional terms such as "upper," "lower," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the utility model. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these directional terms are intended for illustration only and should not be construed as limiting. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
