LED is the abbreviation of English lightemittingdiode (light emitting diode), and its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing all around then, plays the effect of protection internal core.The wafer that the core of light emitting diode is made up of p type semiconductor and n type semiconductor has a transition zone between p type semiconductor and n type semiconductor, be called p-n junction.In the PN junction of some semi-conducting material, the minority carrier of injection and majority carrier compound tense can discharge the form of unnecessary energy with light, thereby electric energy directly is converted to luminous energy.

Mostly adopt metal fin in the known as can be known LED heat radiation of first to file, or in conjunction with modes such as heat pipe, cooling chip, soaking plate, radiator fans, have generally that radiating effect is not good, radiating rate inadequately rapidly, shortcomings such as complicated, the cost height of radiating module structure, and have in the radiator structure of required collocation and design for unnormalized, so light fixture that must design specialized can use.This is existing known technology and has maximum shortcoming, and this shortcoming is into an industry difficult problem extremely to be overcome.

The utility model content

Main purpose of the present utility model is to provide a kind of provides illumination to use, and except that having splendid radiating effect, has more the LED electricity-saving lamp that must not change light fixture and can directly replace bulb use effect.The technical solution of the utility model is achieved in that a kind of LED electricity-saving lamp mainly includes: led module, and described led module is located on the baseplate; Baseplate, described baseplate are that thermal conductivity good metal substrate constitutes; Circuit arrangement, described circuit arrangement are located in the heat radiation lamp socket, connect described led module and external power source; The heat radiation lamp socket, described heat radiation lamp socket is the nonmetal formation of the good tool multi-pore structure of thermal diffusivity, and straight forming becomes the lamp socket profile, and described heat radiation lamp socket has inner fovea part, and the openend of inner fovea part is connected with the baseplate sealing.Wherein, described heat radiation lamp socket outer rim is provided with metallic sheath, insulation sleeve and the power contacting plate of bulb special use, and described metallic sheath and power contacting plate electrically connect with circuit arrangement respectively, and described baseplate is provided with lampshade.Wherein, described circuit arrangement is provided with the splicing ear of projection lamp socket special use, and described splicing ear is convexly equipped with out heat radiation lamp socket bottom outer rim, and described baseplate is provided with reflector.Described baseplate has depressed part, and described led module is located at described depressed part.Wherein, described baseplate is provided with can the forming convection action of a plurality of quantity and the perforation that improves radiating effect.Wherein, described heat radiation lamp socket is provided with in order to increase the lines of cooling surface area.

Beneficial effect after the employing technique scheme is: LED electricity-saving lamp of the present utility model can directly form general bulb profile, and have radiating effect concurrently, can directly replace known bulb uses, except that having splendid radiating effect, have more and must not change the effect that light fixture can directly be replaced bulb, promptly the utility model can directly use on old light fixture.
