Abstract

The utility model discloses a kind of LEDbulb lamp, it comprises lampshade, light source module, lamp holder, stopper; Described lampshade lower end and lamp holder affixed, form an airtight space, light source module lower end is fixed on lamp holder by stopper, and the top of light source module is placed in lampshade; The liquid of insulating heat-conductive is full of in the confined space that described lampshade and lamp holder are formed.Because the utility model is full of the liquid of insulating heat-conductive in the confined space that lampshade and lamp holder are formed, oily cold-producing medium, under light source module being placed on the liquid level of this liquid, the heat that light source module sends by refrigerating fluid to PC lampshade to external radiation, due to the liquid of insulating heat-conductive and the contact area of PC lampshade large, heat can be faster to external radiation, makes the utility model excellent in heat dissipation effect, long service life.

Description

LEDbulb lamp

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of LEDbulb lamp.

Background technology

Conventional incandescent (tengsten lamp) consume energy high, the life-span is short; under under the overall situation of global resources anxiety, gradually replaced by electronic energy-saving lamp, although electronic energy-saving lamp improves energy-saving effect; but owing to employing the heavy metal element of many contaminated environment, run counter to again the main trend of environmental protection.High speed development LED illumination along with LED technology becomes the only choosing of novel green illumination gradually.LED is far superior to traditional lighting products in the aspect of principle of luminosity, energy-saving and environmental protection.Due to incandescent lamp and electronic energy-saving lamp in the routine use of people still in occupation of very high ratio, in order to cut the waste, LED illumination manufacturer must develop the LED illumination product meeting existing interface and people's use habit, makes people just can use the LED illumination product of a new generation when not needing to change former conventional lamp pedestal and circuit.So LEDbulb lamp is just arisen at the historic moment.LEDbulb lamp have employed existing interface mode, i.e. screw socket, socket mode, and the use habit even in order to meet people has imitated the profile of incandescent lamp bulb.As shown in Figure 1, a kind of LEDbulb lamp commonly used, it is primarily of compositions such as lampshade 1 ', light source module 2 ', lamp holders 3 '; Described lampshade 1 ' lower end and lamp holder 3 ' affixed, form an airtight space, light source module 2 ' lower end is fixed on lamp holder by stopper 4 ', and the top of light source module 2 ' is placed in lampshade 1 '.This LEDbulb lamp commonly used, dispelled the heat by modes such as radiating seats, radiating effect is poor, affects the service life of LEDbulb lamp.

Utility model content

The purpose of this utility model is the LEDbulb lamp providing a kind of good heat dissipation effect, long service life.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of LEDbulb lamp, and it comprises lampshade, light source module, lamp holder, stopper; Described lampshade lower end and lamp holder affixed, light source module is placed in lampshade, it is characterized in that: described lamp holder place is provided with a stopper, lamp holder place and lampshade intercept by this stopper mutually, make between lampshade and stopper, to form an airtight cavity, and connect two strip metal wires of lamp holder power positive cathode in the internal package of stopper; Described light source module is fixed on stopper, and is electrically connected with two strip metal wires; The liquid of insulating heat-conductive is full of in airtight cavity simultaneously between lampshade and stopper.

The liquid levels height being full of insulating heat-conductive in described airtight cavity exceedes the end face of light source module, but need with the inwall retention gap at lampshade top.

Described plain conductor surface need have frosting, and one-body molded with stopper

Sealing ring is provided with between described lamp holder and stopper.

After adopting such scheme, because the utility model is full of the liquid of insulating heat-conductive in the confined space that lampshade and lamp holder are formed, oily cold-producing medium, under light source module being placed on the liquid level of this liquid, the heat that light source module sends is by refrigerating fluid to PC lampshade to external radiation, and because the contact area of the liquid of insulating heat-conductive and PC lampshade is large, heat can be faster to external radiation, make the utility model excellent in heat dissipation effect, long service life.

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Accompanying drawing explanation

Fig. 2 is sectional view of the present utility model;

Fig. 3 is three-dimensional exploded view of the present utility model.

Detailed description of the invention

As shown in Figure 2 and Figure 3, the utility model is a kind of LEDbulb lamp, and it comprises lampshade 1, light source module 2, lamp holder 3, stopper 4, sealing ring 5, plain conductor 6, liquid 7.

Described lampshade 1 lower end and lamp holder 3 affixed, a stopper 4 is provided with at lamp holder 3 place, sealing ring 5 is provided with between lamp holder 3 and stopper 4, lamp holder 3 place and lampshade 1 intercept by this stopper 4 mutually, make to form an airtight cavity between lampshade 1 and stopper 4, and two strip metal wires 6 of lamp holder power positive cathode are connected in the internal package of stopper 4, here it should be noted that, plain conductor 6 preferentially carries out blasting treatment on surface, make it the frosting (not shown) that formation one has the irregular distribution of small pore-like, this plain conductor 6 is placed in the mould of stopper 4, and it is one-body molded with stopper 4, namely namely stopper 4 is equipped with two strip metal wires 6 after shaping, like this due to the rubbing surface 61 on plain conductor 6 surface, itself and stopper 4 adhesive force can be increased, guarantee at light source module 2 adstante febre, plain conductor 6 not easily and between stopper 4 produces gap, the sealing characteristics that impact is overall, described light source module 2 is fixed on stopper 4, and is electrically connected with two strip metal wires 6, the liquid 7 of insulating heat-conductive is full of in airtight cavity simultaneously between lampshade 1 and stopper 4.

In an erect condition, liquid 7 liquid level 71 being full of insulating heat-conductive in this confined space highly exceedes the end face of light source module 2, and with the inwall retention gap at lampshade top, be generally 2mm-5mm, have certain surplus to meet insulating heat-conductive liquid when heat expansion.

The above, be only the utility model preferred embodiment, the internal structure of bulb lamp can have multiple, therefore the scope of the utility model enforcement can not be limited with this, namely the equivalence change done according to the utility model claim and description with modify, all should still belong in scope that the utility model patent contains.
