Because the annular heat dissipation channel is arranged in the heat dissipation cylinder, under the condition that the movable cover is opened, outside cold air can enter the heat dissipation cylinder and flow along the annular heat dissipation channel, so that heat on the heat dissipation disc is taken away.

For example, in order to facilitate the flow of air in the annular heat dissipation channel, an air inlet hole is formed in the bottom of the heat dissipation cylinder, and the air inlet hole penetrates through the bottom of the heat dissipation cylinder and penetrates through the side wall of the heat dissipation disc. When the movable cover is opened, cold air flow in the air access hole can enter the annular heat dissipation channel, so that the heat dissipation efficiency is improved.

For example, in order to protect the dual panel lighting apparatus, the diameter of the heat dissipation cylinder is larger than that of the light emitting cylinder, and the air inlet hole is exposed to one side of the light emitting cylinder. In order to cover the light emitting cylinder, a cover ring 77 is further arranged on the heat radiation cylinder in a covering mode, the cover ring is slidably sleeved on the heat radiation cylinder, the two opposite sides of the sliding ring are respectively connected with stretching rods 78, namely, one side of the sliding rod is convexly provided with a stretching rod, the other side of the sliding ring is also convexly provided with a stretching rod, the end parts of the two stretching rods are respectively connected to the two opposite sides of the movable cover, namely, one stretching rod is connected to one side of the movable cover, and the other stretching rod is connected to the other side of the movable cover. When the movable cover is separated from the heat dissipation cylinder, the cover ring can slide along the outer side wall of the heat dissipation cylinder and expose the light emitting cylinder, so that the light emitting cylinder can automatically dissipate heat. In addition, in order to facilitate the sliding of the two stretching rods, two opposite side walls of the heat dissipation cylinder are respectively concavely provided with sliding grooves, and the bottom surfaces of the sliding grooves are arc-shaped and are concavely arranged on the side walls of the heat dissipation cylinder. For example, in order to facilitate the sliding of the stretching rod, a sliding layer is disposed on a bottom surface of the sliding groove, the stretching rod is a circular rod, and the stretching rod is slidably attached to the sliding layer. The two stretching rods can slide along the sliding grooves by arranging the sliding grooves on the two opposite side walls of the heat dissipation cylinder, so that the cover ring can be guided to slide conveniently, the cover ring cannot rotate, and the heat dissipation cylinder can be sleeved with the cover ring accurately.
