Phase change inhibited fin radiator LED lamp

Abstract

The invention provides a phase change inhibited fin radiator LED (Light-emitting Diode) lamp which comprises a heat radiator structure, a light-emitting component and a power supply assembly, wherein the heat radiator structure comprises a first substrate, a second substrate and a plurality of phase change inhibited heat transfer plates; the first substrate and the second substrate are correspondingly arranged in a parallelly spaced manner; the phase change inhibited heat transfer plates are positioned between the first substrate and the second substrate, and are arranged in a radially distributed manner; heat superconduction pipelines in special shapes are formed in the phase change inhibited heat transfer plates, and are filled with heat transfer working media; the light-emitting component is positioned on the surface, far away from the phase change inhibited heat transfer plates, of the first substrate; and the power supply assembly is positioned on the surface, far away from the phase change inhibited heat transfer plates, of the second substrate. A radial heat radiator is rapid in heat conduction; the efficiency of heat-dissipation fins is high; the temperature difference is low; the efficiency of the heat-dissipation fins and the temperature difference hardly change with the changing of the areas of the phase change inhibited heat transfer plates; and the areas of the phase change inhibited heat transfer plates are free of limitation.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a phase change suppressing finned radiator LED lamp. Background technique [0002] High-power LED lights are widely used in urban squares, large assembly workshops, warehouses, ports, factories, stadiums and other indoor and outdoor partial or key lighting places. At present, all high-power LED street lamps sold on the market are based on traditional heat transfer mechanisms and corresponding heat transfer technologies. Efforts to improve heat transfer technologies on all heat transfer paths (including the use of heat pipes, fins, chip substrate materials with excellent thermal conductivity, etc.) are still difficult to break through the bottleneck of chip heat dissipation, especially for high-power LED lamps. The problem of heat dissipation is more prominent, which leads to higher light decay and short life of LED lamps, which affects the popularization and use of LED lamps. Contents ...
