[0002] As a common lighting equipment, downlights are widely used in offices, halls, shopping malls and other occasions. The most important installation method is to embed them into pre-prepared holes in the ceiling or wall. Recently, as LED technology becomes increasingly mature, downlights with LED light sources are increasingly used. However, in order to transfer the heat generated by the LED light source, LED downlights need to be equipped with heat dissipation devices such as heat sinks.

[0003] In the prior art, the Chinese patent document (patent number: CN202022684298.6, patent name: A downlight wiring structure and downlight) discloses in the technical scheme that "it includes a downlight body; a bottom plate is arranged inside the downlight body; a wire hole is arranged from the rear end of the downlight body to the bottom plate; the bottom plate is provided with a wire groove at the wire hole, and a wire pressing piece is also provided on the wire groove; the wire hole introduces the wire from the rear end of the downlight body to the inside, and the wire groove and the wire pressing piece are used to guide and press the inserted wire to realize the electrical connection between the components inside the downlight body and the external power supply or device."

[0004] Combined with the description and drawings of the patent document, in the above scheme, a plurality of heat dissipation fins are arranged on the top of the downlight body, but the height of the heat dissipation fins is relatively high, so that the grooves formed by adjacent heat dissipation fins are relatively deep. When the downlight body is installed on the ceiling, it is easy for a lot of dust to accumulate in the grooves, and it is not convenient to clean the downlight body. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art, provides an easy-to-clean LED lamp accessory and a lighting device thereof, and can overcome the defects of the prior art mentioned in the background technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] An easy-to-clean LED lamp accessory comprises a shell, wherein a plurality of heat dissipation bars are distributed on the end surface of the shell, the heat dissipation bars are flat, adjacent heat dissipation bars are formed with grooves, the end surfaces of the grooves are flat and parallel to the end surfaces of the heat dissipation bars.

[0008] Furthermore, the width of the heat dissipation strip is 8 to 12 mm, the height of the heat dissipation strip is 2 to 4 mm; and the width of the groove is 10 to 14 mm.

[0009] Furthermore, second arc positions are provided at both ends of the heat dissipation strip.

[0010] A lighting device comprises any one of the above-mentioned easy-to-clean LED lamp accessories.

[0011] Furthermore, mounting positions are provided on both sides of the shell, and a torsion spring is engaged and connected to the mounting position. The torsion spring includes a spring body, one end of the spring body is connected to the first connecting part, and the other end of the spring body is connected to the second connecting part.

[0012] Furthermore, a clamping block is arranged in the installation position, the end of the first connecting part is clamped on the clamping block, and the end of the second connecting part is arranged with an armrest cover.

[0013] Furthermore, the end of the armrest cover forms a first arc position.

[0014] Furthermore, the shell is provided with a step position, and the step position is provided with a lampshade.

[0015] Furthermore, the housing is provided with a wire hole, and limiting members are provided on both sides of the wire hole, and the limiting members are arranged in the housing.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The flat design of the heat sink makes the height of the heat sink shorter than the width, so that the depth of the groove formed by adjacent heat sinks is shallow. When the lighting device is installed on the ceiling, dust will not accumulate in the groove, and the groove and the end surface of the heat sink are flat, which is convenient for cleaning with a cleaning cloth. Second arc positions are provided at both ends of the heat sink. The second arc position design plays a protective role, avoiding damage caused by collision of the edge of the heat sink, and also avoiding injuries to the user when cleaning the end surface of the shell.
