Abstract

The utility model provides a radiation structure for a high power light emitting diode lamp set. The utility model is mainly composed of a light emitting diode, a radiation plate, a heat conducting rubber pad and a base plate assembly. The radiation structure adopts the principle of rapid heat conduction. That is to say, when an embodiment is a high power lamp set (such as a street lamp, or a projection lamp, or a traffic signal lamp, etc.), high heat produced by a plurality of concentrated light emitting diodes is conducted and radiated in a homogeneous mode, which can lead the temperature of the lamp set to be quickly lowered. The utility model has the advantages that the utility model can ensure that when the light emitting diode is positioned in a sealed lamp shade to work under high power for a long time, the utility model can effectively avoid the phenomenon that because of high heat, the lamp set is burnt to be damaged; the high heat of the lamp set is greatly reduced; the utility model can prevent the loss of electric energy in a high heat mode, etc.

Description

The High Power LED lamp cooling structure

Technical field

The utility model belongs to a kind of radiator structure, refers to a kind of High Power LED lamp cooling structure especially.

Background technology

In field of light fittings, household light fixtures is from early stage high wattage bulb structure, progressive is lamp tube structure (fluorescent tube), extremely the most extensively use power conservation type fluorescent tube (as: PL lamp) and bulb (the power saving electricity bubble of tool stabilizer) at present from the lamp tube structure differentiation again, in the middle of short many decades, household light fixtures has tangible progressive in fact.But, for the high power light fixture of high projection of demand and height illuminance, but rest in high power consumption (equal'sing high risk) the field for a long time always, remove the required high power consumption problem of this kind light fixture and do not talk, only high heat and the security two large problems that is just produced just enjoyed query.Especially, be used on the purposes such as street lamp or projecting lamp.Use down because this kind light fixture lampshade must be in airtight fully bad condition, therefore, make lamp heat constantly climb sharply in confined space, leading along with use is dangerous increases relatively, and its main cause is " heat radiation " problem.

Therefore, for the street lamp of high power consumption and high power or projecting lamp etc., there is the rudiment of improvement to form then.In correlation technique and document record at present, all be to adopt to do replacement scheme with light emitting diode, its main cause is that light-emittingdiode itself has: characteristics such as far away, the poly-optical activity of high luminosity, projection distance is good, when making it be used to high-power illumination, meet environmental demand and should have ready conditions with projection; Wherein, more most important, be exactly low and high the province electrically of power consumption of light emitting diode; One can low by power consumption (the saving energy) significantly reduce use danger; Two obtain easily, with low cost for the light emitting diode material, and then ask for the advantage of reducing production costs; Certainly, this two big advantage is used in the field of light fittings maximum business opportunity and inducement can take place also just with light-emitting diodes.

But; with the light emitting diode is replacement scheme; on actual face, remain and to break away from " lamp heat " problem; characteristic with light emitting diode itself; high heat causes burning problems, is well known, therefore; be the normal operation for a long time of protection light-emitting diode lamp, " lamp heat " problem then becomes anxious problem to be solved.

The utility model content

Task to be solved in the utility model provides a kind of High Power LED lamp cooling structure, this radiator structure is made up of light emitting diode, heat sink, heat conduction rubber cushion and board unit, wherein, light emitting diode, be to be arranged to marshalling and most concentrated light emitting diodes according to the substrate respective amount, and the lead foot that makes each light emitting diode is by passing the default Kong Weihou of heat sink, puncture again in the heat conduction rubber cushion, last and the position seam of substrate corresponding aperture make it become simultaneously property luminescent panel; Heat sink, made for the metallic plate of high conductance, can accept by the heat that the heat conduction rubber cushion the is guided function of dispelling the heat; The heat conduction rubber cushion, made for soft rubber, be folded between heat sink and the substrate, have the heat of absorption and derive the heat function; Substrate is positioned at heat conduction rubber cushion below, mainly is for each light-emittingdiode lead foot location and seam, makes whole numerous and concentrated light emitting diode, all can reach proper alignment and the purpose of concentrating by the substrate orientation ability.

High Power LED lamp cooling structure of the present utility model is to carry out heat conduction in the heat conduction rubber cushion in the mode of dredging; through the heat conduction rubber cushion heat is being conducted in the heat sink face; make area of dissipation form the heat radiation function of large tracts of land; especially; the Homogeneouslly-radiating advantage of the face heat radiation tool of being implemented that machine spreads out can be protected and concentrate and each light-emittingdiode of marshalling, to guarantee that light emitting diode is in airtight lampshade; the implemented for long periods high power operates, and effectively prevents the problem of high hot scaling loss.

The specific embodiment

At first see also shown in Figure 3ly, the member of this case integral body is made up of with substrate 4 assemblies: light emitting diode 1, heat sink 2, heat conduction rubber cushion 3, and wherein: the high luminosity kenel of light emitting diode 1 employing is arranged at 2 of heat sinks respectively with proper alignment and centralized system; Make its formation " face " illumination and projection kenel, as shown in Figure 2; Implementing on the structure, heat conduction rubber cushion 3 is located in the centre of heat sink 2 and substrate 3, when being installed with light emitting diode 1, it then is the two ends pin (as shown in Figure 1) that utilizes light emitting diode 1 to be had, after passing the default position, hole 21 of heat sink 2, the heat conduction rubber cushion 3 that directly punctured, the position, hole 41 of establishing tool again in substrate 3 at last connects seam; As shown in Figure 4.Continue as shown in Figure 3, aforementioned heat conduction rubber cushion 3 is that soft rubber is made, has good the closing property function of moulding, particularly, after light-emittingdiode two lead foots 11 punctured heat conduction rubber cushion 3, these heat conduction rubber cushion 3 formed time holes of wearing then have and are close to the kenel function of inclusion in light emitting diode lead foot 11, give on the heat conduction rubber cushion 3 with heat conduction and transfer that light emitting diode lead foot 11 is produced.

Please return shown in Figure 1ly, an A is put at light emitting diode 1 end pin 11 tops places for thermal source produces; And the described heat conduction rubber cushion 3 of leading portion can be derived light emitting diode 1 thermal source, indication is A heat partly just, wears time hole by heat conduction rubber cushion 3, carries out conductive force to be close to the inclusion mode, this heat of deriving distributes through fin again, can reach the purpose of quick heat radiating.
