Abstract
The invention discloses a radiator for an LED working condition lamp. The radiator comprises a hollow radiator body and cooling fins; the cooling fins include first cooling fins and second cooling fins; the first cooling fins are arranged on the outer wall of the radiator body in a V-shaped structure; the second cooling fins are arranged on the outer wall of the radiator body between two connected first cooling fins; and the heights of the second cooling fins are gradually increased along the first cooling fins.
Description
Technical field
The invention belongs to heat sink technology field, be specifically related to a kind of LED operating mode lamp radiator.
Background technology
As everyone knows, so-called LED refers to light emitting diode, as one, current extensive use develops new type light source rapidly to LED light source, have energy-conservation compared with conventional light source, efficiently, volume is little, life-span is long, fast response time, driving voltage is low, the advantages such as shock resistance brilliance, thereby can develop expansion industry size rapidly, market share, industry tendency leads under, its technology is also being constantly updated and in-depth, but the maximum technology barriers that restricting at present LED light source development are exactly heat conduction and the hot settlement issues of LED encapsulation, it is the heat dissipation problem of LED, LED is as light source, conventionally all need long continuous firing, even if for this cold light source of LED, work also can produce a large amount of thermal accumlations for a long time, this just requires the radiator operating efficiency of LED light source good, can remove to dredge heat energy by shorter pathway, reduce the infringement that excess Temperature brings to chip as far as possible, current way is that LED chip is encapsulated into heat sink falling on main support, then heat sink fall main support install be fixed on a large-scale radiating element, such as heat-radiating substrate, or aluminum base plate, heat sinkly fall being fixedly connected with normally between main support and radiating element and realize by two kinds of modes, the first is via heat-conducting cream transfer of heat, it two is that practical tin cream is by the mode of reflow soldering transfer of heat, and most importantly the technique of these two kinds of modes is all connected between radiator at LED chip and will produces high temperature, very easily hurt LED chip, cause luminous flux to decline, LED encapsulating structure damages, electrical parameter changes, light decay increases severely.
In general, in industry, traditional radiator normally designs according to concrete applicable cases, size is relatively fixing, and versatility is poor, and some producer is to adopt small-sized fans forced heat radiation for the radiating mode of LED at present, the method cost is high, fault rate is large, also can make the size of whole product larger, simplifies not.
Summary of the invention
Goal of the invention: the problem and shortage existing for above-mentioned prior art, the object of this invention is to provide a kind of LED operating mode lamp radiator.
Technical scheme: the invention discloses a kind of LED operating mode lamp radiator, comprise radiator body and the radiating fin of inner hollow, described radiating fin comprises the first radiating fin and the second radiating fin, described the first radiating fin is V-shape structure and is arranged on described radiator body outer wall, described the second radiating fin is arranged on the radiator body outer wall between two connected the first radiating fins, and described the second radiating fin height increases progressively successively along described the first radiating fin.
As further optimization of the present invention, between the first adjacent radiating fin of the present invention and the second radiating fin spacing be spacing between two the first radiating fins that face mutually 2-2.5 doubly.
As further optimization of the present invention, the outer surface of the first radiating fin of the present invention is provided with some louvres.
As further optimization of the present invention, the outer surface of the first radiating fin of the present invention is provided with some conical heat radiation projections.
As further optimization of the present invention, the first radiating fin upper end inner surface of the present invention is provided with some sheet fin.
Beneficial effect: the present invention compared with prior art, have the following advantages: the present invention adopts the first radiating fin, the second radiating fin and the fin that is positioned at the first radiating fin inner surface are to strengthen the heat dispersion of radiator, the spacing of the first radiating fin of the present invention and the second radiating fin is in ensureing radiator integral heat dispersion, avoid influencing each other between the first radiating fin and the second radiating fin, and the present invention is provided with conical heat radiation projection at the outer surface of the first radiating fin, greatly improve the radiating effect of the first radiating fin, the present invention is simple in structure, be specially adapted on operating mode lamp that power is larger, there is good economic benefit.
