In this way, The auxiliary LED light-emitting part can play a normal lighting effect, and when the lamp is not powered on, it can use the sealed upper cover to cover the protruding opening, and the heated and raised mounting core is not raised, which is different from the The auxiliary LED light-emitting parts are all accommodated in the heat dissipation cup to protect the auxiliary LED light-emitting parts and play the role of waterproof and dustproof.

The sealing upper cover is connected, and the second end of the elastic wire is connected to the sealing lower cover. When the sealing upper cover moves away from the direction of the protruding opening, the sealing upper cover is used to pass the elastic ribbon The lower sealing cover is moved to rotate relative to the rotating shaft. At this time, the lower sealing cover moves towards the direction close to the upper sealing cover, that is, the lower sealing cover moves away from the movable hole, and makes the The movable hole is open, so that when the lamp is energized, the protruding opening and the movable hole can be respectively communicated with the outside world, so that the effect of convection and heat dissipation can be enhanced. For example, a reflective layer is provided on a side of the sealing upper cover facing the heat dissipation cup, and the reflective layer reflects the light emitted by the auxiliary LED light emitting element so that it can better irradiate to the outside.

As another example, in one embodiment, the heat dissipation bearing base of the outdoor landscape lighting fixture undertakes the main heat dissipation task, that is, the actual heat dissipation amount undertaken by the heat dissipation bearing base is the largest. In order to pursue better heat dissipation performance, usually The heat dissipation bearing base will be designed as a solid structure. However, the heat dissipation bearing base of the solid structure is too bulky, which is not conducive to transportation and handling, and wastes materials. Based on the above reasons, in order to make the heat dissipation bearing base both light in weight and The advantage of good heat dissipation performance is usually to open a plurality of through heat dissipation holes or heat dissipation vents on the heat dissipation bearing base, and the outside air flows from one end of the heat dissipation holes or heat dissipation vents to the other end of the heat dissipation holes or heat dissipation vents. In order to achieve the effect of air convection heat dissipation, and then to improve the overall heat dissipation performance of the heat dissipation bearing base, that is, to use the airflow flowing outside to take away the heat on the heat dissipation bearing base to improve the overall heat dissipation performance, and to open multiple through The heat dissipation holes or heat dissipation vents can also achieve the effect of light weight. However, the design of using heat dissipation holes or heat dissipation vents to achieve convective heat dissipation still has the following problems: because the heat dissipation holes or heat dissipation vents are located on the heat dissipation carrying base Inside the base, external impurities are easy to enter and deposit in the heat dissipation holes or heat dissipation vents, resulting in the problem of accumulation of impurities in the heat dissipation bearing base. For example, impurities include dust, water vapor, and insects. Another example, the accumulation of impurities is Dust, water droplets and/or insect shells etc.

An example is, in order to reduce the problem of impurity accumulation in the heat dissipation bearing base, and to have the advantages of light weight and good heat dissipation performance, for example, in the outdoor landscape lamp described in any embodiment of the present invention, The heat dissipation bearing base includes: a base body, a heated push-off component and a heated lift-off component, the heated push-off component is arranged in the base body, and the heated push-off component is used to make the base The inner space in the main body communicates with the outside world, and the heated opening assembly is arranged on the base body, and the heated opening assembly is used to communicate the base body with the outside when heated; wherein, the base body Bearing the main actual heat dissipation, the heated ejector assembly is used to cut off the communication relationship between the ventilation cavity in the base body and the outside world when not heated, and to prevent impurities from entering.

The heated opening assembly is used to close the inner space of the base body to prevent the entry of foreign impurities, and the heated opening assembly is used to automatically open when heated, that is, the partial structure of the heated opening assembly is the same as that of the When the base body is separated, the inner space in the base body is opened, so that the inner space in the base body communicates with the outside world, thereby achieving the effect of convective heat transfer. The base body includes a box body, a first sliding ring, a second sliding ring and a supporting base plate, the box body has a hollow structure, the box body is provided with a ventilation cavity, and the box body is provided with an air inlet and an air outlet , the air inlet and the air outlet are respectively communicated with the ventilation cavity, and the air inlet and the air outlet are aligned, the first sliding ring is arranged around the edge of the box, and the The air inlet communicates with the inner space of the first sliding ring, the sliding sleeve of the second sliding ring is placed outside the first sliding ring, the first sliding ring is provided with a first air inlet hole, and the second sliding ring is provided with a first air inlet hole. The sliding ring is provided with a second air inlet hole communicating with the outside world, the edge of the supporting bottom plate is fixed to the edge of the second sliding ring, and the first sliding ring faces away from the supporting bottom plate and is opposite to the The second sliding ring is used to communicate with the first air inlet hole and the second air inlet hole when sliding. Wherein, through the ventilation cavity provided in the box, and the hollow structure of the first sliding ring and the second sliding ring, the heat dissipation bearing base can have the advantage of light weight, when the air convection path is as follows: External air - the second air inlet hole - the first air inlet hole - the outer wall of the box, the first sliding ring, the second sliding ring and the supporting bottom plate together form a closed cavity Body-the air inlet-the ventilation cavity-the air outlet-outside air, when in the working state, can realize the effect of convection heat dissipation, thereby improving the overall heat dissipation performance, the second air inlet and the second air inlet When the first air inlet hole is not connected, the first sliding ring is used to prevent external impurities from entering into the outer wall of the box body, the first sliding ring, the second sliding ring and the supporting bottom plate. enclosed in a closed cavity. It should be pointed out that each of the shape memory alloy ejecting springs of the heated ejection assembly is in a heated state, and each of the shape memory alloy shielding sheets of the heated flip assembly is in a heated state, that is, when heated, it is Refers to the heat generated when each of the LED light-emitting parts of the outdoor landscape lamp works and emits light, which is transferred to the heat-dissipating bearing base, so that each of the shape-memory alloy ejecting springs of the heated ejecting assembly is heated, and the heat is lifted. Each of the shape memory alloy shielding sheets of the component is heated. Of course, when the heated push-off component is not heated, and the heated flip component is not heated, it refers to the LED light-emitting parts of the outdoor landscape lamp Power off and no light.
