The device is characterized in that the radiation device also comprises a tube-shaped radiation cover made of ametal material; the radiation cover is arranged outside the reflection cover and the reflection cover is covered with the radiation cover; and additionally, a plurality of radiating fins are arranged on the periphery of the radiation cover. The invention has the advantage that by adding the radiation cover on the prior MR16 structure, the radiation ability of MR16 is strengthened. Furthermore, the MR16 LED light source with the structure has the longer service life of more than 3500 hours, and the power can reach 6 to 15w or even higher.
Description
Technical field
The present invention relates to a kind of radiator structure of LED shot-light, especially a kind of all models that are applicable to are the radiator structure on the light fixture of MR16.
Background technology
Heat radiation one is to being one of maximum restriction of LED application.LED also can produce great heat in luminous, and these heats will influence the performance and the service life of LED product greatly if can not effectively discharge.
The structure of application number is 095220939 Taiwan patent disclosure a kind of MR16 comprises as shown in Figure 1: a Lamp cup is to be horn-like and to comprise and dwindle end, an and bellend that this bellend also is concaved with a containing groove; One base (9) is that this that be mounted on this Lamp cup dwindles end, and this base also comprises two power supply contacts; One LED source is to be mounted in this containing groove of this Lamp cup; One light source driving circuit plate is to be mounted in this containing groove of this Lamp cup, and this light source driving circuit plate also is electrically connected to this LED source respectively, reaches this two power supply contact of this base; One lens are to be mounted in this containing groove of this Lamp cup and to be positioned at this LED source top; And a lampshade (1), be this bellend that is covered on this Lamp cup.Described lampshade adopts metal material to make, and comprises and have most radiating fins, and lampshade comprises the cover body and the cover end (3), and described cover body uses as reflector simultaneously, is used for led light source is enclosed in cover body at the bottom of the described cover.MR16 has limited apparent size because of the fixed dimension of these peripheral external members, so can run into very big difficulty when handling heat dissipation problem.Therefore, the MR16 of this structure approximately can only have 1-3 watt power in the market, if improve power, then because heat radiation is not enough, burns out the diode (LED) light source easily, shortens the service life of diode (LED) light source.
Summary of the invention
The objective of the invention is to: providing a kind of has the same size but brighter LED MR16 with traditional MR16 light fixture in the market, owing to adopted novel radiator structure, longer service life, reach more than 35000 hours, power can reach 6-15w or more than, and be designed to replace fully the profile and the size of existing MR16 product.
The technical solution adopted in the present invention is as follows: a kind of heat abstractor of long service life and energy-saving LED sending light, comprise the reflector and the cover end of making by metal material, described heat abstractor also comprises the heat dissipating housing of being made by metal material of a tubular, this heat dissipating housing is located at the outside of described reflector and described reflector is covered on wherein, and described heat dissipating housing periphery is provided with several dissipation fins.
After shot-light has added heat dissipating housing, because being metal material, reflector, the cover end and heat dissipating housing make, and heat conductivility is fine, so the heat that shot-light gives out is very fast through reflector and heat dissipating housing dispersion, and radiating rate and efficient improve greatly.
Described reflector comprises cover body and joint, and this joint outer wall is provided with external screw thread; Described heat dissipating housing comprises cover body and joint, and this inner nosepiece wall is provided with internal thread; Described reflector and heat dissipating housing are fixed together by above-mentioned screw thread.
Being threaded will be that the reflector that metal material is made closely contacts with heat dissipating housing equally, helps the conduction of heat, faster the heat that led light source produced in the reflector is dispersed in the surrounding environment.
Comprise a pedestal and joint at the bottom of the described cover, wherein, this joint outer wall is provided with external screw thread; Described reflector comprises cover body and joint, and this inner nosepiece wall is provided with internal thread; At the bottom of the described cover and reflector be fixed together by above-mentioned screw thread.
By above-mentioned helicitic texture, the bottom of the cover end and reflector and heat dissipating housing is all closely contacted, what heat can be very fast like this comes out from the reflector conducted inside.
The cover body bottom of described heat dissipating housing is provided with the pore more than three.Because the structural characteristics of MR16 cause most of heat all to concentrate on the cover end, therefore offering pore near the bottom of the heat dissipating housing that covers the end, help distributing fast of heat.
The pore of the cover body bottom of described heat dissipating housing evenly distributes in described cover body bottom, is for heat also can be distributed uniformly like this.
The circle that is shaped as of pore is put in the cover body bottom of described heat dissipating housing, and this shape is processed easily, and better appearance.But also can be as required the shape of pore be made as rectangle or ellipse etc.
The cover body top of described reflector is provided with plural pore, is for the heat in the reflector being delivered in the heat dissipating housing, distributing by heat dissipating housing more like this.
The pore on the cover body top of described reflector evenly distributes on described cover body top, is in order to produce stack effect, the cross-ventilation effect to be strengthened, quickening heat is distributed like this.
The pore on the cover body top of described reflector be shaped as circle, this shape is processed easily, and better appearance.But also can be as required the shape of pore be made as rectangle or ellipse etc.
The height of described heat dissipating housing is 26mm-100mm.The height of increasing heat dissipating housing can increase area of dissipation, so that better heat radiation.
Beneficial effect of the present invention is: the present invention has increased the heat-sinking capability of MR16 by increase heat dissipating housing on original MR16 structure.This structure is a very big breakthrough, and the MR16 led light source longer service life of this structure has been installed, reach more than 35000 hours, power can reach 6-15w or more than.
