Abstract
The utility model discloses an electrode support extended heat radiation type array LED diode; the structure comprises an electrode (2) connected with an LED diode (1), and the LED diode is characterized in that the electrode (2) extends downwards to form a radiating fin. The electrode part of the LED diode extends out of a package body integrally and vertically, so as to enlarge the contact surface between the electrode and the air, thus increasing the heat radiation capability under the situation of not enlarging the transverse area of the LED diode; furthermore, a heat radiation support is further added on the side surface of the electrode, thereby realizing better heat radiation effect. Simultaneously, the electrode is thickened, thereby reducing the resistance of a circuit and generating less heat. The electrode support extended heat radiation type array LED diode can not only improve the heat radiation function of an LED light emitting diode, but also reduce the transverse area of the electrode of the LED light emitting diode.
Description
Technical field
The utility model relates to a kind of electrode suppor and extends heat radiation shape array LED diode, belongs to LED diode packaging technology field.
Background technology
The LED diode has characteristics such as the DC power supply of employing, low-voltage power supply, supply power mode diversity, spendable environment is more than traditional electric light, light decay is little, with the 20w fluorescent lamp is example, continuous illumination power consumption in a year 175 degree, power consumption is low, and the brightness height can also be used the environment-protecting clean energy such as solar energy, wind energy.The LED diode service life reaches decades to change and to be maintained as the cost that original calculation will be saved tens to tens ordinary lamps, therefore is one of at present the most popular illuminating product.Chinese patent 200720200408.9 discloses a kind of multiple light courcess light-emitting diode, a plurality of light-emitting diodes can be installed in a transparent encapsulating body, in use find, a plurality of light-emitting diodes are arranged closely, make heat increase, and existing light emitting diode construction normally dispel the heat by the metal electrode of diode below, because metal electrode has only relatively thinner one deck, the light-emitting diode of arranging is many again, and radiating effect is not ideal enough.
Summary of the invention
The purpose of this utility model is: provide a kind of electrode suppor of good heat dissipation effect to extend heat radiation shape array LED diode, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: structure comprises the electrode that connects the LED diode, and electrode extends to form fin downwards.
Above-mentioned electrode suppor extends heat radiation shape array LED diode, is provided with reflective pit on electrode, and the LED diode is located in the reflective pit, is provided with second electrode in the electrode side, a pin connection electrode of LED diode, and another pin connects second electrode.
Above-mentioned electrode suppor extends heat radiation shape array LED diode, is provided with cooling stand in the electrode bottom.
Above-mentioned electrode suppor extends heat radiation shape array LED diode, and being shaped as of electrode is cylindrical, cylindrical shape, square, square frame shape, bar shaped or many bar shapeds of being arranged in parallel.
The utility model is the further achievement in research of applicant on Chinese patent 200720200408.9, vertically extend outside the packaging body by electrode part integral body the LED diode, to add the contact-making surface of large electrode and air, can under the situation that does not strengthen LED diode horizontal area, increase heat-sinking capability like this, add cooling stand in the electrode side, radiating effect can be better.Simultaneously, with the electrode overstriking, reduced the resistance of circuit, the heat of generation still less.Compare with prior art, the utility model has reduced the gathering of LED diode chip for backlight unit heat in packaging body, not only can improve the heat sinking function of LED light-emitting diode, can also reduce the athwartship plane utmost point of LED light-emitting diodes pipe electrode.
