For example, to describe the specific structure and beneficial effects of the heat dissipation mechanism in further detail, please refer to fig. 3, the heat dissipation mechanism 50 is installed on a side of the board body away from the LED lamp bead. For example, the heat dissipation mechanism includes a heat dissipation chassis 51 and a heat dissipation cover 52, and the heat dissipation cover is disposed on the heat dissipation chassis. In order to dissipate heat, the top of the heat dissipation cover is provided with heat dissipation holes 520, which are circular holes. The heat dissipation holes are used for dissipating heat on the heat dissipation chassis. The heat dissipation cover is concavely provided with two exposed depressions, and the two exposed depressions are respectively positioned at two opposite sides of the heat dissipation cover, for example, one exposed depression is arranged at one end of the heat dissipation cover, and the other exposed depression is arranged at the other end of the heat dissipation cover. For example, the exposed recess is semicircular, and the diameter of the exposed recess is larger than that of the heat dissipation hole. The heat dissipation chassis comprises a box body 511 and a heat dissipation base body 512 arranged in the box body, wherein the heat dissipation base body is made of metal with high heat conductivity coefficient. For example, the heat dissipation substrate is an aluminum alloy substrate. Two opposite ends of the box body are respectively provided with two airflow holes, the two exposed recesses are respectively aligned with the two airflow holes, and when the two exposed recesses expose the two airflow holes, airflow in the airflow holes can overflow, so that hot air in the box body can overflow. For example, the diameter of the exposure recess is larger than the diameter of the airflow hole. The heat dissipation mechanism further comprises two tension springs, the two tension springs are respectively arranged at two ends of the box body, the tension springs are located between the heat dissipation base body and the box body, one ends of the tension springs are connected to the box body, the other ends of the tension springs are connected to the heat dissipation cover, the heat dissipation cover is movably arranged on the outer side of the box body in a covering mode, and therefore the box body is closed, and the heat dissipation base body is closed in the box body. For example, the heat dissipation holes are formed in the top of the heat dissipation cover. The box body is a rectangular body and is arranged on the plate body. For example, an accommodating space is formed in the box body, and the heat dissipation base is arranged in the accommodating space. Under the pulling of the tension spring, the heat dissipation cover closes the accommodating space, and meanwhile, the exposed recess is staggered with the airflow hole, so that the airflow hole is closed by the heat dissipation cover, and heat dissipation holes of the heat dissipation cover are also closed, thereby preventing dust and moisture.

For example, the heat dissipation base body is a rectangular body and is convexly arranged in the box body. For example, the heat dissipation base is integrally formed with the case. The periphery of the heat dissipation base body and the box body are arranged at intervals, a mounting slot 5111 is formed between the heat dissipation base body and the box body, and the mounting slot is used for heat dissipation and circulation. For example, the heat dissipation base is provided with a plurality of heat dissipation channels 5121, and the diameters of the heat dissipation channels are different. The heat dissipation channel extends along the length direction of the heat dissipation base body and penetrates through the side wall of the heat dissipation base body. The heat dissipation channel communicates with the airflow hole through the mounting slot. When the airflow hole is opened, the heat dissipation channel can carry out the heat in the heat dissipation base body and lead the heat out to the outside through the airflow hole.

For example, in order to open the two airflow holes and the heat dissipation hole when the power is turned on, the heat dissipation mechanism further includes a plurality of support pieces 56 made of memory alloy, the support pieces being respectively disposed at corners inside the case body, the support pieces being located inside the mounting slots. One end of the supporting sheet is connected to the box body, and the other end of the supporting sheet is connected to the heat dissipation cover. When the lamp with the adjustable irradiation angle is powered on, the temperature of the supporting sheet rises due to heat conduction, so that elastic deformation occurs, for example, the supporting sheet extends and lifts the heat dissipation cover, the heat dissipation cover overcomes the pulling force of the tension spring and gradually gets away from the box body, the exposed recess is aligned to the airflow hole, and the airflow hole is communicated with the outside atmosphere. For example, the support sheet includes a base and an extending tip portion disposed on the base, the base is fixed on the case, the extending tip portion is sheet-shaped and extends in a bent manner, and the extending tip portion abuts against the bottom of the heat dissipation cover. For example, the extended tip portion is connected to the bottom of the heat dissipation cover.

For example, in order to seal the heat dissipation hole when the airflow hole is sealed, an overflow hole 5122 is formed in the middle of the heat dissipation base, a sealing column 55 is convexly disposed at the bottom of the box body, the sealing column is convexly disposed in the overflow hole and convexly disposed to the top of the heat dissipation base, a flow guiding gap is formed between the sealing column and the side wall of the overflow hole, and the flow guiding gap penetrates through the heat dissipation base. For example, the overflow aperture communicates with a plurality of the heat dissipation channels therein, thereby facilitating turbulent airflow in a plurality of directions. For example, the closing column includes a supporting body 551 having a conical shape protruding from the bottom surface of the receiving space, and a closing body 552 having a cylindrical shape and formed on the top of the supporting body. For example, the closing body is exposed to the top surface of the heat dissipation substrate. The closing body protrudes into the heat dissipation hole. The diameter of the closing body is equal to that of the heat dissipation hole. When the side wall of the heat dissipation cover closes the two airflow holes, the closing body closes the heat dissipation holes, so that the heat dissipation mechanism forms a completely closed state, and the inside and outside air flow is isolated, thereby preventing dust or moisture from invading into the accommodating space of the box body, and playing the dustproof and moistureproof effects. When the heat dissipation base body is heated, the support sheet can push the heat dissipation cover to move, the side wall of the heat dissipation cover can expose the airflow hole in the box body, the closing body of the closing column can expose the heat dissipation hole in the heat dissipation cover, so that air can enter the accommodating space from the heat dissipation hole and then enter the plurality of heat dissipation channels of the heat dissipation base body through the overflow hole, finally the heat of the heat dissipation base body is carried and flows out from the airflow hole in the box body, and therefore the heat dissipation efficiency of the bulk device is improved. And when the heat dissipation mechanism is cooled, the support sheet is restored to the original shape and contracts due to the characteristics of the memory alloy. At the moment, the two tension springs pull the heat dissipation cover to cover the box body, at the moment, the two airflow holes are sealed by the side wall of the heat dissipation cover, and the heat dissipation holes in the heat dissipation cover are sealed by the sealing columns in the box body, so that the heat dissipation mechanism can play a dustproof and moistureproof role.

For example, in order to improve the heat dissipation effect of the heat dissipation mechanism, the top surface of the heat dissipation base body is further provided with a plurality of heat dissipation auxiliary holes, and the plurality of heat dissipation auxiliary holes are communicated with the plurality of heat dissipation channels. For example, the heat dissipation auxiliary hole penetrates the heat dissipation base. The extending direction of the heat dissipation auxiliary holes is perpendicular to the extending direction of the heat dissipation channels, so that cold air introduced into the heat dissipation holes can be conveniently introduced into the heat dissipation channels. For example, in order to increase the guiding effect, so that the cold air can smoothly enter the plurality of auxiliary heat dissipation holes, a plurality of guiding fins are further disposed on the heat dissipation base, the guiding fins are disposed at intervals, and the guiding fins are disposed on the periphery of the auxiliary heat dissipation holes and extend obliquely toward the heat dissipation holes. The guide wing is provided with a guide cambered surface. The guide cambered surface extends towards the heat dissipation hole in an inclined mode, so that heat in the heat dissipation hole can be smoothly guided, and cold air can enter the heat dissipation auxiliary hole. Meanwhile, due to the arrangement of the guide fins, the guide fins can be cooled by the cold air in the process of guiding the cold air so as to assist in heat dissipation, and therefore the heat dissipation effect of the heat dissipation mechanism can be improved. For example, in order to prevent the blocking effect on the transverse flow of the cold air, a plurality of communication holes are formed on the guide fin, and the communication holes penetrate through the guide fin. For example, in order to avoid the blocking effect of the guide fins on the heat dissipation cover, the heat dissipation cover can be smoothly covered on the box body, and the tops of the guide fins and the heat dissipation cover are arranged at intervals, so that a space is reserved, and the sealing columns can be sealed in the heat dissipation holes of the heat dissipation cover. For example, the heat dissipation substrate is further provided with a plurality of air inducing holes, the plurality of air inducing holes are formed in the side wall of the heat dissipation substrate, and the extending direction of the air inducing holes is perpendicular to the extending direction of the heat dissipation channel. Through the arrangement of the air guide holes, the heat dissipation channel and the auxiliary heat dissipation holes, the quality of the heat dissipation base body can be lightened, the contact area of the heat dissipation base body and air is increased, namely, the heat dissipation area of the heat dissipation base body is increased, and therefore the heat dissipation efficiency is improved.

For example, in order to prevent the heat dissipation cover from being easily opened, a plurality of guide pieces are convexly arranged on the side wall of the box body, and the guide pieces are made of memory alloy. The guide sheet body is arranged between the side wall of the heat dissipation cover and the side wall of the box body to increase the friction force between the heat dissipation cover and the box body so as to ensure the sealing performance of the heat dissipation mechanism. For example, the guide blades extend obliquely with respect to the side walls of the box. When being heated, the guide sheet body can be stretched and is attached to the side wall of the box body in a parallel and level mode, so that the support sheet can lift the heat dissipation cover, and the heat dissipation cover moves relative to the box body. When the device cools off, the guide lamellar body can the reconversion to transversely extend, support hold in the lateral wall of cooling lid with between the lateral wall of box body, increase frictional force between the lateral wall of cooling lid with between the lateral wall of box body, in order to prevent the cooling lid is opened at will. For example, the guide sheet body is provided with a through hole which is correspondingly communicated with the airflow hole of the box body. When the support sheet supports the heat dissipation cover, the guide sheet body extends and is attached to the box body, and at the moment, the air flow holes are communicated with the exposed recesses through the through holes, so that hot air can flow out conveniently. When the support sheet is restored, the airflow hole is blocked by the side wall of the heat dissipation cover, and the guide sheet body is restored and bent, so that the through hole and the airflow hole are staggered, the airflow hole can be blocked, and meanwhile, the exposed recess is also staggered relative to the airflow hole.
