Description

Corn lamp

Technical Field

Background

The LED has the characteristics of energy conservation, environmental protection, long service life, small volume and the like, and is widely applied to the field of illumination. The heat dissipated by the LED during illumination needs to be conducted out through the medium in time, which may shorten the service life of the LED and even damage the LED. At present, the technical scheme for solving the problem of heat dissipation generally adopts aluminum materials to dissipate heat and assists some air convection modes to conduct heat to air. For example, in the case of an LED corn lamp for daily lighting, a sectional material or the like is usually used for heat dissipation or a heat sink is not used, which is likely to cause poor heat dissipation effect and shorten the service life of the lamp.
