The first end of the heated raising rod is connected with the outer side wall of the heat dissipation cup, and the first end of the heated raising rod is connected with the second end of the transverse heat transfer rod in a manner of being adjacent to the second end of the transverse heat transfer rod, so that when the LED luminous body emits light, the mounting heat dissipation base can transfer heat to the transverse heat transfer rod, further, the heat transferred to the heat dissipation cup by the transverse heat transfer rod can be quickly transferred to the transverse heat transfer rod, the second end of the heated raising rod is connected with the sealing upper cover, the first end of the heat dissipation cup is provided with an extension port, the second end of the heat dissipation cup is provided with a movable hole, the sealing upper cover is arranged on the extension port and used for shielding the extension port, and when the heated raising rod is heated and raised, the sealing upper cover is driven to move in a direction away from the extension port so as to open the extension port, that is, when the mounting heat dissipation base sequentially transfers heat from the LED illuminant to the transverse heat transfer rod, the heat dissipation cup and the heated raising rod, the heated raising rod is deformed by heating, so that the sealing upper cover originally covering the extension opening moves in a direction away from the extension opening, so that the extension opening is open, and the heat dissipation effect is good, of course, when the heated raising rod is heated, i.e., the LED illuminant is not lit, the mounting heat dissipation base does not absorb heat from the LED illuminant, i.e., when the opening and closing lamp is not powered on, the heated raising rod is not raised, and at this time, the sealing upper cover is in a state of shielding the extension opening, and at this time, a dustproof and waterproof effect can be achieved, for example, when the lamp is not opened in daytime, a dustproof and waterproof effect can be achieved, when the lamp is turned on at night, a better heat dissipation effect can be achieved. The heat transfer ring is arranged on the inner side wall of the heat dissipation cup, the heat transfer ring is arranged close to the first end of the transverse heat transfer rod, the heat transfer ring can better absorb heat from the first end of the transverse heat transfer rod, the first end of the heated raised installation core is fixed with the heat transfer ring, and the auxiliary LED light-emitting unit is arranged at the second end of the heated raised installation core, so that when the LED luminous body emits light and the extension opening is open, the auxiliary LED light-emitting unit is driven to pass through the extension opening when the heated raised installation core is heated and raised, namely the auxiliary LED light-emitting unit extends out of the extension opening to the external environment and is exposed outside the heat dissipation cup, and thus the auxiliary LED light-emitting unit can achieve a normal lighting effect, when the lamp is not electrified, the sealing upper cover can be used for shielding the extension opening, the heated and raised installation core is not raised, and the installation core and the auxiliary LED light-emitting unit are accommodated in the heat dissipation cup, so that the auxiliary LED light-emitting unit is protected, and the waterproof and dustproof effects are achieved. The rotary core is arranged at the edge position of the movable hole, the sealed lower cover is connected with the rotary core in a rotating mode, the sealed lower cover is used for shielding the movable hole, the first end of the elastic wire is connected with the sealed upper cover, the second end of the elastic wire is connected with the sealed lower cover, the sealed upper cover is far away from the extending opening, and when moving in the direction of the extending opening, the sealed upper cover is used for driving the sealed lower cover to rotate relative to the rotary core through the elastic wire, at the moment, the sealed lower cover moves towards the direction close to the sealed upper cover, namely, the sealed lower cover moves towards the direction far away from the movable hole, and the movable hole is opened, so that when the lamp is powered on, the extending opening and the movable hole are respectively communicated with the outside, and therefore the convection heat dissipation effect can be enhanced. For example, a side surface of the sealing upper cover facing the heat dissipation cup is provided with a reflection layer, and the reflection layer reflects light emitted by the auxiliary LED light emitting unit, so that the light is better irradiated to the outside.

It is to be noted that, in the present invention, the heating means that when the heat generated by the LED light emitting body during operation is transferred to the heated lifting rod and the heated lifting installation core, the heated lifting rod and the heated lifting installation core are heated, and the heated lifting rod and the heated lifting installation core are both made of shape memory alloy, and are both made of shape memory alloy of the existing material, as long as the heated deformation can be realized, and of course, a person skilled in the art can flexibly select from the materials of the existing shape memory alloy according to the inventive concept. Among them, Shape Memory Alloy (SMA) is an alloy material which can completely eliminate its deformation at a lower temperature after heating and temperature rise and recover its original Shape before deformation, i.e. an alloy which returns to an initial state, i.e. an alloy having a "Memory" effect; of course, considering that the cost is high because the material of the heated lifting rod and the heated lifting installation core is the shape memory alloy, the design is extremely suitable for the field of high-grade lamps which are extremely sensitive to external impurities or have other requirements in the current use field, and of course, the design is also suitable for the field of common lamps, and after the cost of the shape memory alloy is reduced, the lamp based on the design of the application can be more widely applied and favored by consumers.

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.
