Description

The light fixture radiating subassembly

Technical field

The utility model belongs to the radiating subassembly technical field of light fixture, is specifically related to be used for the LED light fixture, with the light fixture radiating subassembly of good heat radiating and decorative effect.

Background technology

Light emitting diode (LED) is advantage such as brightness height, power consumption are low, long service life because of having, and the fields such as lighting and electronic installation that are widely used in are as illuminating source.But the LED lamp is supervened high heat in high brightness, and the chip temperature of LED lamp must be controlled at below 80 ℃, electric energy could be changed into luminous energy rather than heat energy.Under luminous continuously duty,, can cause burning of High Power LED simultaneously, influence service life, increase use cost if heat can not get in time distributing.

For the LED light fixture that family uses, because it need adopt universal lamp holder, as the hickey and the grafting shape of the mouth as one speaks, the illuminator of LED light fixture part should have corresponding holder structure, and has high heat-sinking capability.Existing LED light fixture is in order to satisfy the demand, generally adopt and outside the illuminator of LED lamp, be covered with the effect that metal shell is realized reflection ray and heat radiation, the most common structure is the broadening formation metal shell, and the main heat radiation mode that adopts is carried out the heat conduction between this housing and the illuminator, and radiating efficiency is low.

Another radiating mode is a heat radiation type, promptly in the bonding fixing metal fin heat radiation of the back side of illuminator.For example the Chinese patent ZL 200620139036.6 that announced on October 17th, 2007 provides a kind of light fixture that is provided with the High Power LED radiator, it comprises light fixture, lens, light emitting diode and radiator, radiator is the structure that is provided with the cylinder dress on the disk in vertical mode, this disk is provided with groove, the back side of light emitting diode base is connected by the mode of glue with bonding with the back side of radiator disk, groove on boss on its light fixture lamp socket cylinder inner wall and the radiator disk is being connected in fastening mode by securing member under the buckle state mutually, an end of the end and lens in the lamp socket of light fixture, the other end of lens all is connected in the mode of mutual roof pressure with the base of light emitting diode.This light fixture adopts directly and the fixing radiator heat-dissipation of light emitting diode base bonding, can have certain radiating effect, but there are many defectives in it.At first, for the ease of cooperate installation with lamp socket, must fix a cover body outside radiator, this cover body will make the radiating effect of radiator reduce; Moreover the connected mode of adhesive structure is peeled off can making under the continuous high temperature between light emitting diode base and radiator disk, can't realize heat loss through conduction; At last, the face shaping of this light fixture is not attractive in appearance, and the coml acceptable degree is limited.

The utility model content

The purpose of this utility model provides a kind of good looking appearance, radiating efficiency height, can be applicable to the radiating subassembly of the household LED light fixture of various lamp socket interfaces, it can obviously improve the configuration design space and the external aesthetic property of LED light fixture, consumer's acceptable degree height, can effectively improve the service life of LED lamp luminescence assembly, and applicable to the LED luminescence component of various moulding.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of light fixture radiating subassembly comprises that one is provided with the radiator of plurality of radiating fins, it is characterized in that described radiator inside has a hollow cavity, and the outer wall of hollow cavity is provided with the radiating fin of longitudinal divergence.

Specifically, the hollow cavity of described radiator is the metal body, and the outer wall arranged distribution of described metal body is radiating fin longitudinally, and radiating fin is outwards dispersed setting with metal body axis.

Described radiator is the heat dissipation metal body of the outer fixed axis of a metal tube to radiating fin, and the height of metal tube one end is less than the height of radiating fin, makes an end of radiator form the hollow recess that can install luminescence component.

The bottom of described hollow recess is an end of metal body, and the sidewall of hollow recess is the radiating fin end, offers the lampshade fitting recess on the radiating fin of described hollow recess top edge.

The length of radially dispersing of described radiator is increased to the other end gradually by an end of metal tube, forms a bell radiator with camber line outline.

Described radiator is the heat dissipation metal body of the outer fixed axis of a metal tube to radiating fin, the terminal interface that assembles with the lamp power joint that is provided with of one body of metal tube, offer the heat radiation through hole on the pipe end wall of described metal tube near this interface, described heat radiation through hole is opened on the metal tube tube wall between radiating fin.

Described radiating fin curve-like is in the shape of a spiral radially dispersed along the metal tube tube wall.

The radiator of this radiating subassembly can be directly as the housing of LED light fixture; the shape of radiating fin can freely design; effectively expanded the shape-designing space of LED light fixture; the LED luminescence component can be installed in the recess of this radiator one end; the radiating fin of radiator can extend to the recess upper lamp shade position or longer is set, and other assembly of LED light fixture is played a good protection.The other end at this radiator offers the heat radiation through hole, the heat that produces of LED luminescence component can conduction like this, radiation and cross-ventilated mode outwards distribute, the radiating fin of radiator is good looking appearance not only, it more can omnibearingly outwards be dispersed heat rapidly, effectively guarantees the reasonable operating temperature of LED luminescence component.Cavity by radiating subassembly inside can be with the interface of the lamp power street corner assembling of LED luminescence component and the installing of the radiating subassembly other end, this interface can be family general spiral interface or interface, and realization cooperates with existing family expenses Edison base and grafting lamp socket.

Vertically arrange along the radiating fin that outwards disperse the axis of radiator hollow tube, no matter the horizontal or vertical installation of this LED light fixture all can realize good heat radiation, the shape of radiating fin can design according to aesthetic standard, it is big to can be designed as the radical length that an end disperses, the footpath line length that the other end is dispersed is little, makes the entire heat dissipation body present the outline of bell-jar.Certainly radiating fin also can be dispersed setting outward by screw, and improving its aesthetic appearance should not influence radiating effect again.

The beneficial effects of the utility model are, the good looking appearance of this light fixture radiating subassembly, radiating efficiency height, can be applicable to the household LED light fixture of the various lamp socket interfaces of assembling, the configuration design space and the external aesthetic property of LED light fixture have obviously been improved, consumer's acceptable degree height, and prolonged the service life of LED lamp luminescence assembly, and applicable to the LED luminescence component of various moulding.
