Abstract

An LED lamp with a changeable size comprises a substrate which is provided with LED lamp beads in a packaging mode, a controller which is electrically connected with the LED lamp beads, a base connected with the substrate and a lamp cover connected with the base. The lamp cover is arranged at the end, connected with the substrate, of the base. The base comprises a base body connected with the substrate, a radiator connected with the base body and a closing device connected with the base body. The radiator is arranged on the outer wall of a pipeline in a sleeving mode, the radiator comprises a radiator body connected with the pipeline and a plurality of radiating fins connected with the outer wall of the radiator body, and the radiating fins are bent elastic metal fins. The closing device comprises a first closing plate which is arranged between a connecting plate and the radiator body and a second closing plate which is connected with the end, far away from the connecting plate, of the radiator body. According to the LED lamp with the changeable size, the heat on the substrate is transmitted into the radiator through the base body, and the heat is radiated out through the bent radiating fins. The bent radiating fins can achieve the radiating effect, and the overall size of the LED lamp can also be reduced by contracting.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a volume-variable LED lamp. Background technique [0002] LED (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is a kind of electric light source without filament, which directly converts electrical energy into light energy. [0003] LED lights have the characteristics of energy saving and long life, avoiding the trouble of changing bulbs frequently, and are favored by more and more users. However, the heat dissipation problem of LED lights is also a key issue, which seriously affects the light efficiency and life of LED light sources. Traditional LED lights have low heat dissipation efficiency, resulting in high temperature of the LED light source, which affects the light efficiency and life of the LED light source. Contents of the invention [0004] Based on this, it is necessary to provide a volume-variable LED lamp...
