Description

A kind of compact type large power led light source

Technical field

The utility model relates to the high-power LED light source of the lighting in luminous field, particularly a kind of compact conformation.

Background technology

Great power LED is commonplace as the light source of lighting, desk lamp, wall lamp, setting-in lamp and street lamp or the like, but the high-power LED light source that uses on these products can not change, if light source damages, that just repairs quite trouble, even whole desk lamp tool also will be scrapped.At present, the lighting that uses in the building of family expenses or commercialization is the overwhelming majority or conventional lamp still, uses conventional lamp to have low-cost advantage, and great power LED is novel light source, although advantage is a lot, whole lighting field is thoroughly reformed.Conventional lamp is as using incandescent lamp, fluorescent lamps etc. are simple as the fitting structure of light source, although the service life of light source is long not as the high-power LED light source life-span, but damaging the back buys conveniently, and low price, people have been accustomed to existing occupation mode, and, its structure of the various light fixtures that use all only is fit to conventional light source basically at present, various forms of lamp holders such as bayonet type, screw type, fluorescent tube lamp holder or the like, if high-power LED light source also can be convenient as the light source of conventional lamp, can be directly installed on traditional light fixture, with the general exchange of the light source of conventional lamp, that high-power LED light source has striden forward major step again undoubtedly in the application of lighting field in other words.Great power LED also has a heat dissipation problem to need to solve as the light source of light fixture, because the architectural characteristic of self causes its institute that must have good radiating condition could normally give play to LED to have superiority.Way in the past is to use special heat abstractor such as heat-conducting plate, fin or the like, but, obtain better heat radiating effect for great power LED, need to use larger volume and, be that every watt of need make the aluminium about 30 grams as at present than the metal fin of heavy amount.If fin is too small, LED will cause damaging because of bad the intensification rapidly of dispelling the heat, thereby the range of application of great power LED and style all be subjected to bigger restriction, also is difficult to do its appearance and size equally small and exquisite with the light source of conventional lamp.Therefore, the volume that how to dwindle fin can guarantee better heat radiating effect again simultaneously, becomes the common problem of paying close attention to and expecting to solve as early as possible of people.

Summary of the invention

In order to address the above problem, the purpose of this utility model is the compact type large power led light source that a kind of compact conformation, good illumination effect, good looking appearance is provided, can be used in conventional lamp.

The technical solution of the utility model is:

A kind of compact type large power led light source, comprise lamp body, be provided with great power LED in the lamp body, lamp body also comprises tubulose radiator and the diffuser that lamp holder, core are found time, great power LED is installed or is fitted in the outside that described radiator is provided with the end face of fin, and diffuser is mounted on the radiator and covers in the light penetrating object of great power LED outside, and at least one end of radiator is installed fan, the other end of fan connects lamp holder, is respectively equipped with air inlet and air outlet on described lamp holder and the radiator.

The beneficial effects of the utility model are: because the utility model is provided with the lamp holder with the lamp socket of conventional lamp coupling, also be provided with radiator and fan, dispel the radiating mode good heat dissipation effect of hot body with fan, when guaranteeing great heat radiation effect, can dwindle the volume of fin again significantly, make high-power LED light source compact conformation, volume little, can be easily as the light source of conventional lamp.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of compact type large power led light source of the present utility model, comprise lamp body 1, be provided with great power LED 10 in the lamp body 1, lamp body 1 also comprises lamp holder 2, tubulose radiator 11 that core is found time and diffuser 14, the outside that described radiator 11 is provided with the end face of fin 18 is installed or be fitted in to great power LED 10, diffuser 14 is mounted on the radiator 11 and covers in the light penetrating object of great power LED 10 outsides, radiator 11 at least one ends are installed fan 12, the other end of fan 12 connects lamp holder 2, is respectively equipped with air inlet 20 and air outlet 13 on described lamp holder 2 and the radiator 11.

Radiator 11 is tubular metal bodies that core is found time, be provided with fin 18 in the pipeline, great power LED 10 is installed or is fitted in the outside that described radiator 11 is provided with the end face of fin 18, and diffuser 14 is mounted on the radiator 11 and covers in the light penetrating object of great power LED 10 outsides.One end of radiator 11 is provided with shading fixed head 15, and fixedly on the radiator 11, lamp holder 2 is fixed on the other end of fan 12 to fan 12 by shading fixed head 15, and when radiator 11 when only an end is equipped with fan 12, its other end is equipped with afterbody shading fixed head 16.Be respectively equipped with air inlet 20 and air outlet 13 on described lamp holder 2 and the radiator 11, air inlet 20 can also be arranged on having on other part that is fit to the circulation of air opening between lamp holder 2 and the fan 12, plays the effect of air intake heat radiation equally.During fan 12 work, cold air enters from air inlet 20, under fan 12 drives, cold air is blown in the pipeline of core of radiator 11, the other end of pipeline is equipped with afterbody shading fixed head 16, so air-flow can only flow out from air outlet 13, takes away the heat on the fin 18 simultaneously.

With reference to figure 3, if the length of the more arrangement of great power LED 10 quantity is longer, then the length of radiator 11 can extend relatively, difficulty is wanted in heat radiation, for reaching comparatively ideal radiating effect, radiator 11 two ends are equipped with fan 12, air outlet 13 middle parts are provided with dividing plate 17, the two ends of radiator 11 are equipped with shading fixed head 15, and fixedly on the radiator 11, air outlet 13 is arranged on the middle part of radiator 11 to fan 12 by shading fixed head 15, the dividing plate 17 at air outlet 13 middle parts can avoid 12 pairs in the fan at radiator 11 two ends to blow, and not reaching better heat dissipation effect, dividing plate 17 will separate fully from the air-flow at two ends, and discharges smoothly from air outlet 13.

Diffuser 14 is mounted on the radiator 11 and covers in the light penetrating object of great power LED 10 outsides, with reference to Fig. 4, Fig. 5 and Fig. 6, diffuser 14 is the part circumference that are enclosed in circular or the oval transparent pipe or the pipe of radiator 11 outsides, Figure 4 shows that quadrant, Figure 5 shows that whole circumference, also can be the high printing opacity rod or the bar of oval or other shape, Figure 5 shows that oval pole.Diffuser 14 is fixed on the radiator 11 by shading fixed head 15 and/or afterbody shading fixed head 16, when radiator 11 when only an end is equipped with fan 12, utilizing shading fixed head 15 and afterbody shading fixed head 16 to cooperate can be fixing with diffuser 14, when radiator 12 two ends all are equipped with fan 12, utilize two shading fixed heads 15 diffuser 14 can be fixed, shading fixed head 15 and afterbody shading fixed head 16 also are used for blocking the light that appears from radiator 11 ends simultaneously, and light can be arrived in the specific zone in cover.

More than be preferred implementation of the present utility model, other equivalent technical solutions also should be within protection domain of the present utility model.
