Dynamic heat dissipation led lighting

Abstract

The present invention provides a dynamic heat dissipation LED lighting lamp. The dynamic heat dissipation LED lighting lamp includes a lamp body and a radiator; the radiator and the lamp body are fixed to each other; the radiator includes a large number of soft magnetic heat sinks distributed in parallel at equal distance , each cooling fin has a freely bendable periphery; an electromagnet is fixed in the center of the whole formed by each of the soft magnetic cooling fins; the electromagnet is electrically connected to alternating current. The LED illuminating lamp can adopt a heat sink with a smaller volume to achieve a good heat dissipation effect.

[0002] At present, due to the good energy-saving effect of LED lighting, it has been widely promoted; and a problem encountered in the promotion process is that for high-brightness LED lights, the heat is huge, and LED chips are sensitive to temperature. In high temperature conditions, the performance of the LED will quickly decay, therefore, for a LED lamp with a small volume, it is usually necessary to configure a huge radiator; therefore, the problem of heat dissipation is a major factor restricting the promotion of LED lighting devices. question

[0003] At present, the design of the heat dissipation structure of LED lighting mainly improves the heat dissipation effect by improving the shape and distribution of the heat dissipation fins, but no matter how it is changed, since the current heat dissipation fins are fixed, it can only rely on natural The way of heat dissipation is to dissipate heat to the outside, and its heat dissipation effect is extremely limited; and for some structures with higher requirements, a motor fan structure is configured to perform forced convection heat dissipation. In addition to the cost of the motor itself, it is also necessary to consider the waterproofing of the motor. The cost of the structure leads to a substantial increase in the cost of the heat sink, which is also not conducive to popularization and application
