LED lamp radiator with heat tube function and combined LED illumination lamp

Abstract

The invention relates to an LED lamp radiator with a heat tube function and a combined LED illumination lamp. The radiator comprises a heat tube, radiating fins and a mounting connecting body, whereinthe mounting connecting body comprises a mounting base and a column which is arranged in the center of the mounting base and is provided with an inner hole; the radiating fins are fixedly connected with an outer margin vertical surface of the column, radially and uniformly distributed at the periphery of the outer margin vertical surface of the column and integrally cast with the mounting connecting body; the hole wall of the inner hole of the mounting column is the tubular shell of the heat tube; a copper wire net is attached to the hole wall, or the hole wall is coarsened and processed to form particles, or grooves are processed on the hole wall so as to form a liquid-absorbing core of the heat tube; both ends of the inner hole of the column are sealed, and working liquid is filled in the column. The combined LED illumination lamp comprises 1-100 groups of radiators with LED lamps and an LED light source; and every two radiators are mutually connected by a buckle into a whole. The LED lamp radiator has reasonable structure, small size and better radiation function, and the combined LED illumination lamp has attractive appearance and long service life.

Problems solved by technology

[0002] At present, high-power LED lamps for lighting generally have the problem of poor heat dissipation and serious light decay, which affects the life of the lamp. Recently, there have been a variety of technical solutions to solve the heat dissipation of high-power LED lamps. In summary, one is to use heat pipes and heat dissipation components. The second is to increase the external heat dissipation device, and some use scattered heat dissipation, which can receive different effects. The existing heat pipe or superconducting heat column transmits the heat of the LED lamp to the heat sink or heat dissipation member. Generally, the heat sink or heat sink The heat dissipation component is set outside the heat pipe or the heat pipe is embedded in the heat dissipation component. In this way, the contact between the heat pipe and the heat dissipation component is not particularly close, and its heat dissipation effect is affected. Secondly, most of the heat dissipation components that are matched with the existing heat pipe are connected to the lamp housing. Together, the external heat sink has few heat sinks and simple shape, which cannot meet the heat dissipation needs of high-power LED lamps.

Publication No. CN101113812A "Heat Dissipation Device for LED Light Source" invention patent application discloses a heat dissipation component that combines heat dissipation with a heat pipe and a heat dissipation body made of metal materials. The method that the sheet is set on the heat pipe, therefore, still has the above-mentioned problems

[0003] In addition, the general power of the existing "street lamps with heat dissipation effect" is fixed and cannot be combined at will. The "Heat Dissipation Device for LED Light Source" with the publication number CN101113812A only meets the heat dissipation requirements of a single LED light source. For ultra-high-power LED When multiple LED light sources are combined to form lighting fixtures, the heat dissipation body will be large in size and heavy in weight, and requires a large amount of precious metal copper or aluminum, which is expensive and impractical
