In addition, the cover 150 for line lighting may be detachably coupled to the rail 110 along a second direction that is different from the first direction in which the rail 110 extends. More specifically, the cover 150 for line lighting may be detachably mounted on the rail 110 along a second direction that is a direction crossing the first direction. For example, the cover 150 for line lighting may be detachably mounted to the rail 110 along a second direction, which is a direction perpendicular to the first direction and orthogonal to the first direction. Here, the cover 150 for line lighting may be detachably coupled to the rail 110 at the lower side of the rail 110 along the second direction. Accordingly, the cover 150 for line lighting may be coupled to the rail 150 inserted into the ceiling CE or separated from the rail 150 .

Meanwhile, the cover 150 for line lighting may be engaged with at least a portion of the inner surface of the rail 110 and detachably coupled. That is, the cover 150 for line lighting may be engaged and coupled to the first slide protrusion 111d formed on the rail 110 through the second slide protrusion 151a1 to be described later. In addition, the cover 150 for line lighting includes a cover frame 151 and a diffusion plate 152 .

The cover frame 151 is slidably provided on the rail frame 111 . A part of the cover frame 151 is accommodated in the second accommodating space 111f of the rail frame 111 .

The cover frame 151 includes a coupling plate 151a, a support protrusion 151b, a contact protrusion 151c and an adjusting plate 151d.

The coupling plate 151a may be coupled to the rail frame 111 to fix the cover 150 for line lighting to the rail frame 111 . Here, the coupling plate 151a may be provided as a pair. In the following, a case in which coupling plates 151a are provided as a pair will be described as an example. A pair of coupling plates 151a may contact and be coupled to the inner circumferential surface of the rail frame 111 , respectively.

The coupling plate 151a (ie, the coupling portion 151a) includes a second slide protrusion 151a1. The second slide protrusion 151a protrudes from the pair of coupling plates 151a to the outside of the cover frame 151 and is coupled to the first slide protrusion 111d in a sliding manner. Here, a plurality of second slide protrusions 151a1 are provided and may be arranged vertically. For example, the second slide protrusion 151a1 may be provided in a rack gear shape. Here, the end of the second slide protrusion 151a1 may protrude downwardly. Thus, in the process of inserting the cover 150 for line lighting from the lower side to the upper side into the rail 110, the second slide protrusion 151a1 comes into contact with the first slide protrusion 111d and the coupling part 151a moves inward. It can be tilted at a predetermined angle. Thereafter, the cover 150 for line lighting is further inserted into the rail 110 from the lower side toward the upper side, and the second slide protrusion 151a1 is in close contact with the groove between the first slide protrusions 111d, tilted inward The coupling part 151a may return to its original position (ie, a vertical state). Accordingly, since the cover 150 for line lighting is coupled to be engaged with the first slide projection 111d of the rail 110 through the second slide projection 151a1, it is firmly supported on the rail 110 without departing downward. state can be maintained.

When the second slide protrusion 151a is slidably coupled to the first slide protrusion 111d, the cover 150 for line lighting may be coupled to the rail frame 111. Meanwhile, the above-described coupling plate 151a may be referred to as a coupling portion 151a below. That is, the coupling plate 151a according to an embodiment of the present invention has the same structure and configuration as the coupling portion 151a, only the terms are expressed differently. The support protrusion 151b is a rail on one surface of the coupling plate 151a. It protrudes toward the inside of the frame 111. The support protrusion 151b supports a portion of the diffusion plate 152 so that the diffusion plate 152 can remain coupled to the coupling plate 151a.

The contact protrusion 151c protrudes in a direction opposite to the direction in which the support protrusion 151b protrudes from the other surface of the coupling plate 151a. The contact protrusion 151c may contact the ceiling CE or the sidewall so that a part of the lighting device 100 accommodated inside the ceiling CE or the sidewall does not fall to the inside of the ceiling CE or the sidewall. Meanwhile, the above-described contact protrusion 151c may be referred to as a protrusion 151c below. That is, the contact protrusion 151c according to an embodiment of the present invention has the same structure and configuration as the protrusion 151c, and only the terms are expressed differently.

The protrusion 151c may extend from at least one surface (ie, an outer circumferential surface) of the coupling portion 151a to the outside of the coupling portion 151a. Here, the protrusions 151c may be provided as a pair. In the following, a case in which the protrusions 151c are provided as a pair will be described as an example. The pair of protrusions 151c may extend from the outer circumferential surface of each of the pair of coupled portions 151a. Accordingly, the pair of protrusions 151c may come into surface contact with the lower surface of the ceiling CE. That is, the cover frame 151 is inserted into the rail 110 inserted into the ceiling CE, and in the process of inserting the cover frame 151 into the rail 110, a pair of protrusions 151c are formed. It may contact the ceiling CE. That is, the rail 110 and the cover frame 151 may be disposed inside the ceiling CE, and the protrusion 151c may be disposed outside the ceiling CE while being in contact with the ceiling CE. Accordingly, when the cover frame 151 is damaged, a worker may change the cover frame 151 using the protruding portion 151c. Therefore, a user can more easily maintain and maintain the lighting device 100 .

Also, the protruding portion 151c may extend in a direction crossing the extending direction of the coupling portion 151a. More specifically, the protruding portion 151c may extend in a direction perpendicular to the extending direction of the coupling portion 151a. Here, the thickness of the protrusion 151c gradually decreases toward the end thereof and at least a portion of the protrusion 151c may be formed to be tiltable. As described above, one surface (ie, an upper surface) of the protruding portion 151c may be in surface contact with the ceiling CE. Since the protrusion 151c is formed to be tiltable, the user can more easily hold the protrusion 151c in surface contact with the ceiling CE. Therefore, a user can more easily maintain and maintain the lighting device 100 .

In addition, the protruding portion 151c may be bent downwardly at least at one point toward its end.

The lighting device 100 according to another embodiment of the present invention may include a rail 110, a power module 120, a light source module 130, a clamp 140, and a cover 150 for line lighting. The cover 150 for line lighting may include a cover frame 151 . The cover frame 151 is disposed between the plurality of coupling portions 151a slidably coupled to the rail 110 and the plurality of coupling portions 151a, and at least a portion transmits light emitted from the light source module 130. and a diffusion part 151f for diffusing at least a part of the transmitted light.

Both ends of the diffusion part 151f may be connected to the plurality of coupling parts 151a, respectively. In the following, a case in which the diffusion unit 151f is integrally provided with the plurality of coupling units 151a will be described as an example. Also, the diffusion part 151f may include a first layer 151f1 and a second layer 151f2.

The first layer 151f1 forms an upper region of the diffusion part 151f, is disposed to face the light source module 130, and at least a portion thereof may be formed of a material capable of absorbing light. That is, the first layer 151f may be formed of a material that at least partially absorbs light so that light emitted from the light source module 130 passes through the first layer 151f and the intensity thereof is weakened. For example, the first layer 151f1 may be formed of a material capable of consuming electromagnetic wave energy of light incident on the surface in the form of thermal energy.

The second layer 151f2 may form a lower region of the diffusion part 151f. That is, the second layer 151f2 may be disposed below the first layer 151f1. At least a portion of the second layer 151f2 may be formed of a material capable of light diffusion. Accordingly, the second layer 151f2 scatters the light passing through the first layer 151f1 to radiate the light to a relatively larger area.

It may be formed of a material containing at least one of (Acrylonitrile-butadiene-styrene).

Meanwhile, the diffusion part 151f may be formed to have a uniform surface roughness at its edge. More specifically, the diffuser 151f may have a uniform surface roughness in the central region, and the surface roughness of the edge region may be greater than that of the central region. Accordingly, since the light passing through the diffuser 151f is more diffused at the edge portion, the light can be radiated over a relatively larger area.

Meanwhile, the diffuser 151f may be formed by polishing or grinding the portions (ie, the edge portion and the center portion) formed to have a uniform surface roughness. Accordingly, the surface roughness of the diffusion portion 151f is uniformly formed, and the degree of light scattering can be formed uniformly.
