For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] The linear lamp provided by the embodiments of the present application will be described in detail below in combination with the drawings, through specific embodiments and application scenarios.

[0026] As shown in Figures 1 to 4 The linear lamp disclosed by the embodiments of the present application can include a lamp body part and a mounting bracket part, and the lamp body part is fixed to the mounting base (such as the ceiling) through the mounting bracket. Among them, the lamp body part can include a light shield cover 1, a light shield plate 2, a light transmission piece 3, a lamp panel 5 and a shell 6.

[0027] Referring to Figure 1 and Figure 2 The shell 6 is configured as an open shell in the form of an elongated strip. An installation base plate is arranged in the shell 6 and extends along the longitudinal direction thereof. The installation base plate separates the internal cavity of the shell 6 into two installation spaces in the height direction, one of which is used to install a light source assembly, and the other is used to install a power supply assembly. Specifically, the first installation space on the side of the installation base plate away from the installation base is used to install the lamp panel 5. The second installation space on the side of the installation base plate close to the installation base is used to install the power supply assembly, such as the wire 10, the wire inlet box 11, etc. Among them, the wire 10 is configured to supply power to the lamp panel 5.

[0028] According to a preferred embodiment, the lamp panel 5 is preferably a LED lamp panel. The lamp panel 5 comprises a light source substrate and a plurality of light emitting bodies, i.e. light emitting diodes (LEDs), arranged on the light source substrate. The lamp panel 5 can be fixedly mounted on the housing 6 by means of the first fastener 4. For example, the lamp panel 5 is fixed on the mounting substrate by lamp panel screws away from the mounting base.

[0029] Referring to Figures 2 to 4 The light emitting side of the lamp panel 5 is provided with a plurality of light transmitting members 3. The plurality of light transmitting members 3 are arranged one-to-one corresponding to the plurality of LED lamp beads on the lamp panel 5 to allow the light emitted by the LED lamp beads to be adjusted and emitted through the light transmitting members 3.

[0030] As an example, the bottom surface of each light transmitting member 3 facing the lamp panel 5 can be provided with a plug, and the light source substrate can be correspondingly provided with a matching socket, so that each light transmitting member 3 can be inserted into each socket through each plug to cover or surround each LED lamp bead. In other embodiments, the plug can be provided on the light source substrate, and the socket can be provided on each light transmitting member 3. Alternatively, the plug and the socket can be provided on the light source substrate and the light transmitting member 3 at the same time. The present application does not limit this.

[0031] In the embodiments of the present application, the light transmitting member 3 is preferably a lens. When the light transmitting member 3 is a lens, each lens corresponds to cover the light emitting side of each LED lamp bead and surround each LED lamp bead. Each lens is configured to collimate the light emitted by each LED lamp bead into a parallel light beam and emit it. In other embodiments, the light transmitting member 3 can be a reflective cup or a diffusion cover.

[0032] According to a preferred embodiment, an optical shield 2 is provided on the side of each light transmitting member 3 away from the lamp panel 5. Referring to Figures 2 to 4 The two side walls of the housing 6 are provided with receiving portions extending towards each other. The optical shield 2 is carried by the receiving portions on the two side walls of the housing 6, so as to be arranged across the light emitting side of each light transmitting member 3 to face and receive the light emitted through the light transmitting member 3. In other words, along the height direction of the housing 6, the lamp panel 5, the light transmitting member 3 and the optical shield 2 are arranged in sequence from bottom to top.

[0033] In the embodiments of the present application, a first light emitting portion 201 extending along the longitudinal direction of the optical shield 2 is provided at the substantially central position of the optical shield 2. The first light emitting portion 201 is configured to allow the light from the light transmitting member 3 to emit. The first light emitting portion 201 is symmetrically provided with a first blocking portion 202 on both sides along the width direction of the optical shield 2. The first blocking portion 202 is configured to block the light from the light transmitting member 3 from emitting. Thus, at least part of the light emitted by each LED lamp bead on the lamp panel 5 is emitted through the light transmitting member 3 (such as a lens) and then emitted from the first light emitting portion 201 of the optical shield 2. As a non-limiting example, the optical shield 2 is preferably a silk-screened tempered glass.

[0034] Specifically, the light shielding plate 2 can be made of super white tempered glass, and a black silk print (i.e., the first shielding part 202) is provided on the bottom of the light shielding plate 2, and a narrow light emitting gap (i.e., the first light emitting part 201) is left between the black silk prints. In other embodiments, the first shielding part 202 of the light shielding plate 2 can be formed of a light shielding material, and the first light emitting part 201 can be formed of a transparent material.

[0035] According to a preferred embodiment, the light shielding cover 1 is arranged on the side of the light shielding plate 2 away from the light transmitting member 3 and / or the lamp panel 5. As shown in Figures 2 to 4 , the light shielding cover 1 is configured as an elongated shell similar to the shell 6. The light shielding cover 1 is composed of a top plate and side plates connected to both sides of the top plate in the width direction, and a groove extending in the longitudinal direction is formed thereby. The light shielding cover 1 can be fixedly installed on the shell 6 by means of the third fastening member 14. For example, the groove opening of the light shielding cover 1 is clamped on the shell 6 in a manner of partially surrounding the shell 6, and the side plates on both sides of the light shielding cover 1 are fixedly connected to the side walls of the shell 6 by means of screws / bolts.

[0036] According to a preferred embodiment, as shown in Figure 3 , the side walls of the shell 6 on both sides are partially inwardly protruding to form receiving parts. The receiving parts protrude into the shell 6 to form recessed slots. The light shielding cover 1 can be correspondingly provided with one or more fixing holes at positions corresponding to the slots on both sides. When the light shielding cover 1 is buckled on the shell 6, the third fastening member 14 (such as a screw) is inserted into the slots on both sides of the shell 6 through the fixing holes on both sides of the light shielding cover 1, so as to connect and fix the light shielding cover 1 to the shell 6.

[0037] Further, the side plates on both sides of the light shielding cover 1 are provided with protruding parts extending towards the open groove and towards each other. As shown in Figure 3 and Figure 4 , the light shielding plate 2 is carried by the receiving parts on the side walls of the shell 6 and is arranged across the light emitting side of each light transmitting member 3. When the light shielding cover 1 is buckled on the shell 6, the protruding parts on the side plates on both sides of the light shielding cover 1 are arranged on the top surface of the light shielding plate 2, so as to jointly define the movable space of the light shielding plate 2 with the receiving parts on the side walls of the shell 6. In other words, along the height direction of the shell 6, the lamp panel 5, the light transmitting member 3, the light shielding plate 2 and the light shielding cover 1 are arranged in sequence from bottom to top.

[0038] In this embodiment, the top surface of the light shield 1 is alternately provided with a second light-emitting portion 101 and a second blocking portion 102. That is, in the longitudinal direction of the light shield 1, a second blocking portion 102 is provided between two adjacent second light-emitting portions 101. The second light-emitting portion 101 is configured to allow light emitted through the light shield 2 to exit from the light shield 1. The second blocking portion 102 is configured to block light emitted through the light shield 2 from exiting from the light shield 1. In other words, the light emitted by the lamp plate 5 is output after the light path is adjusted by the light-transmitting element 3, and then sequentially passes through the first light-emitting portion 201 of the light shield 2 and the second light-emitting portion 101 of the light shield 1.

[0039] According to a preferred embodiment, the second light-emitting part 101 of the light shield 1 and the first light-emitting part 201 of the light shield 2 are aligned with each other in the height direction of the housing 6, so that the light emitted by the lamp plate 5 can be directed to the outside of the housing 6 in a basically horizontal manner after the light path is adjusted by the light-transmitting member 3.

[0040] As a non-limiting example, the light shield 1 is preferably a metal housing. A plurality of narrow slits (i.e., second light-emitting portions 101) are formed on the top of this metal housing. These slits (i.e., second light-emitting portions 101) are substantially collinear, thus forming a generally straight line arrangement to allow light emitted via the light shield 2 (such as the first light-emitting portion 201) to exit through these slits. Furthermore, the slits on the top of the light shield 1, i.e., the metal housing, are intermittently connected. That is, adjacent slits are connected by second blocking portions 102, so that light exits only through each slit. By providing the second blocking portions 102, the overall strength of the light shield 1 can be increased, preventing deformation during production and transportation that could affect the size of the light spot.

[0041] It is understood that the first light-emitting part 201 on the light-shielding plate 2 and / or the second light-emitting part 101 on the light-shielding cover 1 may not be located at the center of the lamp. For example, either the first light-emitting part 201 or the second light-emitting part 101 can be offset to one side according to the actual scene requirements to achieve polarized lighting. Specifically, with Figure 2 For example, the second light-emitting portion 101 on the light shield 1 is offset from the central axis of the lamp or the light shield 1, while the first light-emitting portion 201 on the light shield 2 is basically positioned at the central axis. Therefore, the light emitted from the lamp panel 5 is emitted almost directly towards the first light-emitting portion 201 on the light shield 2, while the light emitted from the second light-emitting portion 101 on the light shield 1 is offset from the center of the lamp. In other embodiments, both the first light-emitting portion 201 on the light shield 2 and the second light-emitting portion 101 on the light shield 1 are offset from the central axis of the lamp.

[0042] In some alternative embodiments, the first light exit portion 201 on the light shield 2 and / or the second light exit portion 101 on the light shield cover 1 can be configured to be non-linear. As an example, one or more of the first light exit portion 201 and the second light exit portion 101 can be configured to be any one of a circle, an ellipse, a polygon, or any other geometric shape, or a combination thereof, as required by the actual scenario. For example, the first light exit portion 201 on the light shield 2 and / or the second light exit portion 101 on the light shield cover 1 can be configured to include a plurality of independent light exit holes. It can be understood that the shapes of the plurality of light exit holes can be designed differently depending on actual requirements, so that the light transmitted by the light shield cover 1 can generate light spots of different forms.

[0043] According to a preferred embodiment, the lamp disclosed by the embodiments of the present application further comprises an end cover 7 and a sealing member 8. Specifically, the end cover 7 can be fixed to the two ends of the shell 6 in the longitudinal direction by means of a second fastener 9 (such as an end cover screw) to close the openings at the two ends of the shell 6. Further, the sealing member 8 is installed between the end cover 7 and the opening at the end of the shell 6 to seal the shell 6. As a non-limiting example, one example of the sealing member 8 provided by the embodiments of the present application is a sealing ring.

[0044] According to a preferred embodiment, the lamp disclosed by the embodiments of the present application further comprises a wire 10 and a wire inlet box 11. Specifically, as shown in Figure 2 , the wire inlet box 11 is installed in the mounting space (such as the second mounting space) at the bottom of the shell 6. The two ends of the wire inlet box 11 are respectively connected to the wire 10, so that the wire inlet box 11 and the wire 10 are both laid on the other side of the shell 6 opposite to the lamp panel 5. Preferably, the inside of the wire inlet box 11 is filled with glue for waterproofing the wiring.

[0045] According to a preferred embodiment, the lamp disclosed by the embodiments of the present application further comprises a breather valve 12. As shown in Figure 2 , the breather valve 12 is installed on the same side of the shell 6 as the wire inlet box 11. That is, the breather valve 12 is laid on the other side of the shell 6 opposite to the lamp panel 5. The breather valve 12 is used to balance the air pressure inside the lamp due to thermal expansion and contraction.

[0046] According to a preferred embodiment, the lamp disclosed by the embodiments of the present application further comprises a fixing bracket 13. Specifically, as shown in Figures 1 to 3 , the two sides of the shell 6 are provided with clamping grooves extending in the longitudinal direction thereof. The fixing bracket 13 is configured as a U-shaped clamping groove. The fixing bracket 13 includes a bottom plate and side plates connected to the two sides of the bottom plate, wherein the ends of the side plates on the two sides of the fixing bracket 13 are respectively clamped to the clamping grooves on the two sides of the shell 6. Thus, the fixing bracket 13 can be clamped to fix the side of the shell 6 away from the lamp panel 5, so that the lamp can be installed and fixed to a mounting base (such as a ceiling) by means of the fixing bracket 13.
