Description

Dark area-free LED line lamp Technical Field The utility model relates to the technical field of LED line lamps, in particular to an LED line lamp without a dark area. Background The LED line lamp has the advantages of high efficiency, energy saving, controllable light color and easy realization of continuous linear illumination, and is widely applied to various fields such as building exterior wall decoration. Such lamps are usually composed of a lamp panel comprising LED lamp beads, a lamp body (mostly aluminum profiles) accommodating the lamp panel, and a light-transmitting lamp shade covering the light-emitting surface. In order to effectively seal both ends of the lamp body, protect the internal electric components, and provide a mounting structure, the prior art generally employs end caps which function to define the position of the lamp housing and close both ends of the linear lamp. However, the end caps in the prior art can cause a dark area with brightness attenuation at the light emitting end of the LED line lamp, and when the two line lamps are spliced end to form continuous illumination, a more obvious dark area is formed at the spliced position. This phenomenon is mainly due to the physical shielding effect of the end cap itself. Specifically, the end cap structure blocks light from exiting its corresponding lamp cover region, so that light emitted from the LED lamp bead closest to the end cap cannot fully illuminate the end region of the LED line lamp, thereby forming dark regions at both ends of the single line lamp. When a plurality of LED line lamps are continuously spliced, the dark areas at the end parts of two adjacent LED line lamps are just overlapped and converged near the splicing point, so that the dark area effect of the area is overlapped and obviously amplified, and finally, an obvious dark band or dark point which influences the illumination continuity is formed, and the final illumination quality and the final attractiveness are seriously influenced. It can be seen that there is a need for improvements and improvements in the art. Disclosure of utility model In view of the shortcomings of the prior art, the utility model aims to provide an LED line lamp without a dark area, which aims to solve the technical problem that the end part of the LED line lamp in the prior art has a dark area. In order to achieve the above purpose, the utility model adopts the following technical scheme: a dark area-free LED line lamp comprises a lamp body; the lamp panel is arranged in the lamp body, and LED lamp beads are arranged on the lamp panel at intervals along the length direction of the lamp panel; The lamp shade is arranged in the lamp body and positioned at the light-emitting side of the lamp panel, the tail end of the lamp shade extends to the tail end of the lamp body, and the tail end of the lamp shade is provided with a first concave part; the two first end covers are respectively arranged at two ends of the lamp body, a first notch is arranged on one side of the first end cover, facing the lamp shade, and the bottom of the first notch is lower than the bottom of the lamp shade on the vertical projection plane; The second end cover is correspondingly arranged on the first end cover and is abutted against the first concave part. Further, two fins are arranged on the side wall, close to the lamp panel, of the first end cover, the fins are connected with two side walls of the lamp body through first screws, a supporting block is arranged on one side, far away from the first notch, of the first end cover, and the supporting block is in butt joint with the inner bottom of the lamp body. Further, the shape of the first end cover is matched with the shape of the inner wall of the lamp body. Further, a second concave part is formed in the first end cover, and the second end cover is mounted on the first end cover. Further, the distance between the LED lamp beads and the upper surface of the lampshade is 1.2-1.4 times of the distance between two adjacent LED lamp beads. Further, the lamp body is internally filled with a glue filling layer, the glue filling layer covers the lamp panel, a first water leakage hole is formed in the first end cover, and a second water leakage hole corresponding to the first water leakage hole is formed in the second end cover. Further, a plurality of second gaps are formed in two sides of the lamp panel, and the second gaps are used for enabling the glue filling layer to penetrate into gaps between the lamp panel and the bottom surface of the lamp body.
