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.
The above embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
