[0047] The number of side covers 6 is two, so that one side cover 6 is installed on one end cover 3; wherein the side cover 6 is located on the side of the end cover 3 away from the lamp body 1 and covers the pull pin 52. The side cover 6 is used to cover the non-smooth surface of the end cover 3 (such as the side of the cover portion 31 away from the lamp body 1, the mounting portion 32, etc.), so that the overall appearance of the LED tear bead lamp 100 is smooth and there is no unevenness, and thus the outer surface of the LED tear bead lamp 100 is not easy to accumulate dust, meeting the technical requirements of clean room lamps.

[0048] In combination Figure 7 The end surface 61 of the side cover 6 and the side wall 62 of the side cover 6 are both smooth surfaces, and the connection between the end surface 61 of the side cover 6 and the side wall 62 of the side cover 6 is smoothly transitioned 63; wherein the top of the side cover 6 has a relief opening 622, when the side cover 6 is assembled with the end cover 3, the side cover 6 covers the cover portion 31 and the mounting portion 32 of the end cover 3, and the mounting portion 32 is inserted at the relief opening 622. Through the structural design of the side cover 6, the overall outer contour of the side cover 6 is smooth and not easy to accumulate dust.

[0049] Preferably, the cover portion 31 is formed with a surrounding plate 313, which extends from the cover portion 31 away from the lamp body 1 in the length direction of the lamp body 1, and the surrounding plate 313 extends around the circumference of the cover portion 31, wherein the surrounding plate 313 is formed with a second insertion slot 3131; correspondingly, the inner circumferential wall of the side cover 6 is formed with an insertion rib 621. When the side cover 6 is assembled with the end cover 3, the surrounding plate 313 is interference-fitted with the inner circumferential wall of the side cover 6, and the insertion rib 621 is interference-inserted into the second insertion slot 3131, and at the same time, the outer circumferential wall of the side cover 6 is flush with the outer circumferential wall of the cover portion 31. This design can ensure the tightness and firmness of the connection between the end cover 3 and the side cover 6, so that the outer circumferential wall of the side cover 6 after assembly is flush with the outer circumferential wall of the cover portion 31, which can better avoid dust accumulation at the connection between the side cover 6 and the end cover 3.

[0050] Further, the mounting portion 32 has a second connecting portion 321 and a second outer protruding portion 322, and the second connecting portion 321 and the second outer protruding portion 322 are distributed in a stepped manner. Wherein the second outer protruding portion 322 protrudes outward from the second connecting portion 321 to the top of the LED tear bead lamp 100, and a mounting through hole 3221 is formed on the second outer protruding portion 322; correspondingly, the inner circumferential wall of the side cover 6 is also formed with a buckle 623. When the side cover 6 is assembled with the end cover 3, the buckle 623 is buckled on the top of the second connecting portion 321; this design is conducive to further improving the tightness and firmness of the connection between the end cover 3 and the side cover 6.

[0051] The power module 7 is installed in the cavity 10 of the lamp body 1, and is located between the heat dissipation frame 21 and the top plate part 11 of the lamp body 1, so as to avoid the power module 7 from blocking the light emitted by the light source 22.
