For example, in order to describe the specific structure and beneficial effects of the heat dissipation mechanism in further detail, please refer to fig. 4, the outdoor lighting lamp further includes a heat dissipation mechanism 60, the heat dissipation mechanism includes a heat dissipation cylinder 61, a heat dissipation block and a movable cover 62, the heat dissipation cylinder is connected to the lamp cylinder, and a heat dissipation disc 63 is convexly disposed in the heat dissipation cylinder, the heat dissipation block is disposed on the side wall of the heat dissipation cylinder in a penetrating manner and connected to the heat dissipation disc, the heat dissipation disc is a circular aluminum alloy block, a telescopic rod is convexly disposed on the heat dissipation disc, the telescopic rod is made of memory alloy, and the end of the telescopic rod is connected to the movable cover. For example, in order to facilitate the extension and retraction of the telescopic rod, the diameter of the telescopic rod is gradually reduced along the direction away from the heat dissipation disc. For example, when the heat dissipation cylinder is heated, the heat dissipation cylinder conducts heat to the heat dissipation block and the heat dissipation disc, and meanwhile, the telescopic rod is heated and extends, so that the movable cover is pushed to be away from the heat dissipation cylinder, the heat dissipation cylinder is opened, the heat dissipation disc is exposed to the outside, and heat dissipation of the heat dissipation disc is facilitated. When the heat received by the heat dissipation mechanism is small, heat dissipation can be completed only by the heat dissipation block, so that the movable cover is prevented from being opened, and dust and moisture are prevented from entering the heat dissipation cylinder. When the heat is more, the telescopic rod lifts and opens the movable cover, so that the heat dissipation plate can dissipate heat outwards, and the heat dissipation efficiency of the heat dissipation mechanism is improved. And after the heat dissipation mechanism is cooled, the telescopic rod can be contracted, so that the movable cover is driven to close the heat dissipation cylinder, and dust and the like are prevented from entering the heat dissipation cylinder. For example, in order to avoid the falling of the movable cover, the heat dissipation plate is provided with a blocking piece 64 in a protruding manner, the blocking piece includes a connection column 641 and a blocking cover 642 formed at the end of the connection column, and the lamp holder is connected to the blocking cover.

For example, in order to facilitate the penetration of the blocking member, a penetrating hole is formed in the movable cover, and the connecting column is penetrated in the penetrating hole. For example, in order to accommodate the blocking cover, the movable cover is provided with an accommodating groove, the through hole is formed in the bottom surface of the accommodating groove, the blocking cover is movably accommodated in the accommodating groove, the thickness of the blocking cover is equal to the depth of the accommodating groove, that is, when the blocking cover is accommodated in the accommodating groove, the surface of the blocking cover is flush with the surface of the movable cover.

For example, in order to facilitate heat dissipation, the heat dissipation cylinder is a circular cylinder, the heat dissipation disc is a circular block, a receiving space 643 is formed in the heat dissipation cylinder, the heat dissipation disc is disposed in the receiving space, and the height of the heat dissipation disc is smaller than the depth of the receiving space. In order to further improve the heat exchange efficiency of air, the diameter of the heat dissipation disc is smaller than the inner diameter of the heat dissipation cylinder, namely, an annular heat dissipation channel is formed between the heat dissipation disc and the inner side surface of the heat dissipation cylinder, and the heat dissipation block is arranged in the annular heat dissipation channel in a blocking mode. 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 611 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 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, the air inlet hole is a circular hole. For example, in order to prevent dust from entering the air inlet during cooling, a blocking piece 65 and a pull rod 66 are arranged in the air inlet, the blocking piece is slidably arranged in the air inlet, two opposite ends of the pull rod are respectively connected to the blocking piece and the movable cover, namely one end of the pull rod is connected to the blocking piece, and the other end of the pull rod is connected to the movable cover. For example, the stopper piece is a circular piece. When the movable cover is lifted away from the heat dissipation cylinder by the telescopic rod, the pull rod pulls the baffle establishing piece to move in the air access hole, so that the baffle establishing piece opens the air access hole, cold air can enter the air access hole and flow along the annular heat dissipation channel, and finally flows out from the upper side of the heat dissipation cylinder to take away heat of the heat dissipation disc. For example, because the heat dissipation disc is convexly arranged on the bottom of the heat dissipation cylinder, the air inlet hole may include a through section and a guide section which are oppositely arranged, the through section is arranged on the bottom of the heat dissipation cylinder, and the guide section is only concavely arranged on the side wall of the heat dissipation disc. When the blocking piece moves for a short distance, the blocking piece can be separated from the through section, then the blocking piece moves along the guide section, at the moment, the blocking piece is separated from the bottom of the heat dissipation cylinder, so that outside cold air can enter the annular heat dissipation channel through the through section of the air access hole and flow in the annular heat dissipation channel, and the blocking piece continues to move in the guide section to guide and adjust the movable cover. For example, the tie rod is a cylindrical rod having a diameter smaller than the diameter of the attachment post. In order to provide a small deflection tolerance for the blocking piece, the pull rod is a flexible rod, for example, the pull rod is a rubber rod, and when the blocking piece generates a small deflection, the pull rod can generate a small bending by using the elasticity of the pull rod so as to adapt to the continuous movement of the blocking piece.

For example, in order to facilitate pulling and holding the blocking piece, the pulling rod is connected to the central position of the blocking piece, and the blocking piece can be smoothly pulled and slid in the air access hole through the structural design. For example, in order to facilitate the covering of the movable cover, an embedding ring is convexly arranged on the periphery of the movable cover, an accommodating ring groove is concavely arranged on the periphery of the heat radiating cylinder, and the embedding ring is inserted into the accommodating ring groove, so that the sealing degree of the movable cover is improved, and the heat radiating cylinder can be better sealed to prevent dust and moisture from invading. For example, in order to improve the heat dissipation effect of the heat dissipation block, a plurality of heat dissipation holes are formed in the heat dissipation block, and extend towards the heat dissipation cylinder and extend onto the heat dissipation plate.

For example, in order to protect the outdoor lighting fixture, the diameter of the heat dissipation cylinder is larger than that of the lamp cylinder, and the air inlet hole is exposed out of one side of the lamp cylinder. In order to cover the lamp cylinder, the heat radiation cylinder is further covered with a covering ring 67, the covering ring is slidably sleeved on the heat radiation cylinder, the two opposite sides of the sliding ring are respectively connected with stretching rods 68, namely, one side of the sliding rod is convexly provided with the stretching rod, the other side of the sliding ring is also convexly provided with the stretching rod, the end parts of the two stretching rods are respectively connected with the two opposite sides of the movable cover, namely, one stretching rod is connected with one side of the movable cover, and the other stretching rod is connected with the other side of the movable cover. When the movable cover is separated from the heat dissipation cylinder, the covering ring can slide along the outer side wall of the heat dissipation cylinder and expose the lamp cylinder, so that the lamp cylinder can dissipate heat automatically. 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.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
