Abstract
The utility model relates to an LED structure with broad application ranges. The utility model is characterized in that one surface of radiation fins is provided with a lead frame which is formed by the connection of a sheet-shaped body and lead wires; the sheet-shaped body is fixedly connected with the radiation fins by screws; a luminescent crystal is arranged on the surface of the sheet-shaped body; the luminescent crystal is respectively connected with a positive leading foot and a negative leading foot by two metal wires; a shell body is covered outside the luminescent crystal; the shell body seals the luminescent crystal all around; the lead wires, the positive leading foot and the negative leading foot extend the shell body out; the ends of the lead wires, the positive leading foot and the negative leading foot pass through holes of the radiation fins to the other surface of the radiation fins. The LED has the advantages of good heat dispersion and high mechanical strength.
Description
Technical field
The utility model relates to luminescent device, the splendid LED device of particularly a kind of heat dispersion.
Background technology
Light-emitting diode (light-emitting diode, application LED) more and more widely, but the present problem of light-emitting diode ubiquity poor heat radiation causes brightness and power to improve, and is difficult to competent some application scenario.
Existing light-emitting diode structure is that the positive and negative electrode pin directly-heated of luminescent crystal is welded on the fin, luminescent crystal is fixed on the fin by pin, can cause molten tin after solder joint is heated, come off, bad mechanical strength, luminescent crystal is insecure with being connected of fin, and pin is shorter, and size is limited, cause fin to enlarge, limited the further raising of power.
The positive and negative electrode pin with and luminescent crystal be on the same plane of fin, cooperate when making product with other circuit element, bring inconvenience to wiring, because of many products for compact conformation and miniaturization, all need light source and circuit element to be laid in respectively on the Different Plane of fin, so the range of application of existing light-emitting diode is narrower.
Summary of the invention
The purpose of this utility model provides a kind of light emitting diode construction of applied range, and its heat dispersion is splendid, mechanical strength height, applied range.
The purpose of this utility model is achieved through the following technical solutions: a kind of light emitting diode construction of applied range, comprise luminescent crystal, fin, on the one side of fin lead frame is housed, lead frame is connected and composed by plates and lead-in wire, plates are affixed by screw and fin, luminescent crystal is contained on the surface of plates, luminescent crystal is connected with the negative pole pin with anodal pin respectively by two one metal wires, the outside of luminescent crystal is covered with housing, housing will be sealed around the luminescent crystal, described lead-in wire, anodal pin and negative pole pin stretch out in housing, lead-in wire, the end of anodal pin and negative pole pin is by the another side that passes through to fin in the through hole on the fin.
The utility model has following positive beneficial effect: luminescent crystal is connected with lead frame, and lead frame is to fix with screw with combining of fin, can not come off owing to being heated.
Luminescent crystal is positioned at the one side of fin, and its positive and negative electrode pin passes through to the another side of fin from the through hole from fin, is convenient to connect up with other electron component be connected.
Luminescent crystal positive luminous, the heat that send at the back side is distributed by fin by the fin that passes to of lead frame.Because of lead frame is not subjected to size restrictions, so can strengthen the size of fin arbitrarily, improve heat dispersion, the quantity of luminescent crystal is also unrestricted, can adopt multi-disc, in parallel each other, improving brightness and power, so light-emitting diode of the present utility model can be realized high-power, high brightness.
