Abstract
The invention discloses a light-emitting diode (LED) support, comprising a base body and a recess in the base body, wherein the body wall of the recess is provided with a smooth condensation reflecting surface; the bottom surface of the recess is used for placing a light reflecting surface of a chip, and is provided with a conducting part which is connected with the chip; the recess is provided with an insulating tape which penetrates to the bottom surface; the insulating tape is located under the light reflecting surface, and is used for arranging a first pin of the chip on one side of the insulating tape; and a second pin is arranged on the other side of the insulating tape. The LED support disclosed by the invention is provided with the insulating tape, two pins of the chip are arranged on two sides of the insulating tape, so that the phenomenon that a positive pole and a negative pole are mutually conducted to cause short circuit is fundamentally prevented, and the service life of LED illuminating parts is prolonged.
Description
Technical field
The present invention relates to the LED field, particularly a kind of led support.
Background technology
LED(Light Emitting Diode), light-emitting diode mainly is comprised of support, elargol, wafer, gold thread, five kinds of materials of epoxy resin.
LED be a kind of can be the semiconductor of luminous energy with electric energy conversion, it has changed the principle that the incandescent lamp tungsten filament is luminous and the electricity-saving lamp tricolor powder is luminous, and adopts electroluminescence.According to one's analysis, the characteristics of LED are very obvious, and the life-span is long, light efficiency is high, radiation is hanged down with low in energy consumption.The spectrum of white light LEDs almost all concentrates on visible light frequency band, and its luminous efficiency can surpass 150lm/W.
Led support, the bottom susceptor of LED lamp pearl before encapsulation on the basis of led support, fixedly entered chip, and the positive and negative electrode of burn-oning is once in package shape with packaging plastic again.
Led support generally be copper do (iron material is arranged also at present, aluminium and pottery etc.), because the conductivity of copper is fine, the leaded electrode that connects LED lamp pearl inside of its inside meeting, after LED lamp pearl is in package shape, the lamp pearl can take off from support, and the copper pin at lamp pearl two namely becomes the both positive and negative polarity of lamp pearl, is used for being welded to LED light fixture or other LED finished product.
In the prior art, led support has three-decker, the first plastic layer, middle conductting layer, the second plastic layer, but that pin arranges is unreasonable, and often the both positive and negative polarity mutual conduction causes short circuit phenomenon; Heat radiation need to add mechanism in addition, and, having that light-emitting area is large not, angle is large not, needs other radiation fin, cost is higher.
Summary of the invention
The present invention proposes a kind of led support, has solved the both positive and negative polarity mutual conduction, causes the problem of short circuit phenomenon.
Technical scheme of the present invention is achieved in that
The invention discloses a kind of led support, comprise the recess in base body and the described base body, the body wall of described recess has smooth spotlight camber, the bottom surface of described recess is for being used for the light reflection surface of chip placement, described bottom surface has the conducting portion that is connected with described chip, described recess has the insulating tape that is through to the bottom surface, described insulating tape is positioned under the described light reflection surface, described insulating tape is used for making the first pin of described chip to be arranged at a side of described insulating tape, and the second pin is arranged at the opposite side of described insulating tape.
As the further improvement of the technical program, described conducting portion bottom has fin, and the upper surface of described fin contacts with conducting portion, and lower surface contacts with air.
As the further improvement of the technical program, the shared area of described insulating tape be the bottom surface area 15%～30%.
As the further improvement of the technical program, described fin is copper sheet.
As the further improvement of the technical program, described bottom surface has silver coating.
