Abstract

The utility model provides a novel LED lamp bulb which comprises a radiator, a lamp head cover, an isolation cover and an aluminum base, wherein the radiator is connected with the lamp head cover in an integral way; the aluminum base and the isolation cover are in butt joint, and the aluminum base is arranged inside the radiator together with isolation cover; the lower part of the aluminum base closely clings to an aluminum base plate provided with an LED lamp; the aluminum base, the lamp head cover and the isolation cover are respectively provided with a through hole; the periphery of the aluminum base is in a fin shape; the lamp head cover is sheathed with a lamp head shell; the front end of the LED lamp leans against a front cover; and a lens is positioned between the LED lamp and the front cover. The novel LED lamp bulb has the technical advantages of reasonable design, strong practicability, high technical integration degree and simple and easy installation and maintenance. By adopting the design, two heating sources, a power supply and the LED lamp, are independent, so that the generated heat is not mutually interfered with each other, the whole stability of the lamp bulb is improved, and the market prospect is favorable.

Description

The New LED bulb

Technical field

The utility model belongs to the lamp lighting class of people's life, is specifically related to a kind of New LED bulb of optimizing heat sinking function that has.

Background technology

As everyone knows, light emitting diode is the LED lamp, be to utilize electric energy to be converted into the principle of luminous energy, in two terminals of semiconductor both positive and negative polarity, apply voltage, when electric current passes through, electronics is combined with electric hole, dump energy just discharges with the form of light, rely on the difference of the material that uses, height with its energy makes photon energy produce the light of different wave length, have the brightness height, save advantage electric, that the life-span is long, thereby be widely used in production, various fields in life, but existing LED lamp much exists the bad problem of heat radiation.

But the technology of this traditional LED lamp in the use, the power of actual input only has 15 ~ 20% to convert light to, all the other 80 ~ 85% convert heat to, these heat are not if discharge in good time, can cause the power supply internal temperature too high, the junction temperature of LED is too high, has a strong impact on the luminous efficiency and the service life of light fixture integral body.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model proposes a kind of LED bulb of rational in infrastructure, good heat dissipation effect.

For achieving the above object, the utility model is achieved by the following technical programs: a kind of New LED bulb, by radiator, the lamp holder lid, cage and aluminium base are formed, radiator covers integrated the connection with lamp holder, aluminium base docks mutually also with cage and cage together places radiator inside, aluminium base offer through hole and below be glued with aluminium base, the peripheral week of aluminium base is along being made as the fin shape, the LED lamp is installed on the aluminium base, lamp holder covers and is arranged with lamp head shell, the front end of LED lamp has held cover, is provided with lens in the centre of LED lamp and cover.

The further technical measures of the utility model are, the aluminium base in stating and on all offer through hole.

Compared with prior art, the utlity model has following technical advantage:

1---novel in design, rational in infrastructure, install easy, practicality is high, the thermal resistance of radiator is little, the temperature difference that guarantees each several part in the radiator can be installed on air-conditioning Anywhere within 5 degree, and is applied widely, the promotional value height;

2---because power supply is two different pyrotoxins with the LED lamp, the setting of cage can be kept apart both, forms independently heat dissipation channel, makes both heat energy can not interfere with each other, and has improved whole stability;

3---make full use of the through hole of offering on aluminium base, lamp holder lid, the cage, and in conjunction with the radiating fin of aluminium base week along setting, carry out air exchange and circulation fast with bulb is inside and outside, avoided tradition with the shortcoming of metallic circuit as heat-conducting medium thereby fully take away heat;

4---make whole power supply high power factor more than or equal to 0.95, the high efficiency of power supply is more than or equal to 85%, more environmental protection and energy saving.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is an overall structure cutaway view of the present utility model;

Among the figure: 1, radiator, 2, lamp holder lid, 3, cage, 4, aluminium base, 5, aluminium base, 6, the LED lamp, 7, through hole, 8, lamp head shell, 9, cover, 10, lens.

The specific embodiment

With reference to shown in Figure 1, in the structure of the present utility model, radiator 1 covered for 2 integrated connections with lamp holder, aluminium base 4 is installed on the below of the cage 3 that offers through hole 7, aluminium base 4 together places radiator 1 inside with cage 3, the week of aluminium base 4 is along offering through hole 7 equally, below aluminium base 4, be glued with aluminium base 5, be welded with LED lamp 6 on the aluminium base 5, every LED lamp 6 all is connected with lens 10, front end at lens 10 has held cover 9, and the lamp holder that also offers through hole covers on 2 and is arranged with the lamp head shell 8 that is used to insert electric lamp holder.

During work, because power supply is two different pyrotoxins with the LED lamp, when power supply power supply and driving LED lamp 6 are luminous, the heat energy that power supply sent can be kept apart by cage 3, make that power supply and LED lamp are independent, the heat that both produced can not interfere with each other, and the heat that LED lamp 6 is produced, then be delivered on the aluminium base 4 by aluminium base 5, lateral transport comes on aluminium base 4 then, so just heat point source is become plane heat source and sheds, and the edge of peripheral week of aluminium base 4 is made as its purpose of fin shape and is: after the fin of aluminium base 4 peripheries is heated, hot-air part between fin and the fin can be discharged from, middle air pressure step-down, cold air on every side just can flow to and absorb heat, are drained again then, form the mode of circulation, increase its radiating effect and improve performance, at aluminium base 4, all offer through hole 7 on lamp holder lid 2 and the cage 3, so easier radiator 1 inside that enters into of cold air, heat is in time taken away, increased the stability of light fixture integral body.

According to technique scheme; those skilled in the art according to actual needs; also can design more different structure forms; but the foregoing description is only enumerated for explanation the utility model; be not to be used to limit the utility model; the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.
