Embodiment Construction

[0025] figure 1 , 2 , 3 respectively show the schematic diagrams of the characteristics of three kinds of solar fancy heat sinks. Their structural characteristics (that is, the structural characteristics of sunflowers), the center is the heat conduction column 2 (there are solid and hollow, the figure is solid), and the ribs 3 protrude from the cylindrical surface of the heat conduction column 2. The function of the heat conduction column is to The heat of the LED core is transferred from the end surface (also called the cross section) of the heat conduction column to the fins on the cylinder surface in the form of heat conduction. The advantages of the sunflower structure: the heat conduction part (that is, the heat conduction column) is small in size, the heat conduction path is short, and the heat dissipation area of ​​the fin is large.

Abstract

The invention provides an LED lampwick and an LED illuminating lamp thereof, aiming to solve the problem of heat radiation of an LED. A sunflower type heat radiating fin is adopted, and a heat conducting wick (4) and the LED (1) are designed into an independent part, LED lampwick, which is convenient for the inner encapsulation of the lampwick and the assembly of the whole lamp and is convenient to realize the standard generalization of an LED illuminating lamp part. The cone and thread embedded heat radiating fin structure solves the problem of contact heat resistance between the heat conducting wick (4) and the heat radiating fin and is convenient for the maintenance of the LED lamp. The heat radiating capability is improved by additionally mounting a convection shield (8) through a chimney sucking principle, and the cost is effectively reduced.

Description

Technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to an LED lighting lamp using sunflower cooling fins. technical background [0002] LED lighting, which has attracted worldwide attention due to its energy saving and long life, is considered to be the next generation lighting technology. However, its heat dissipation problem is a major obstacle in the development of LED lighting technology today, and it accounts for a considerable part of the cost of LED lighting. The high cost of the entire lamp restricts the popularization and application of LED lighting. Current heat dissipation devices for LED lighting lamps have a wide variety of structures. The common problem is that the structure is unreasonable, difficult to replace, unable to form a general standard, high in cost, and unsatisfactory in heat dissipation. Contents of the invention [0003] The LED lighting lamp proposed by the present invention is aimed a...
