Description
Technical field
The utility model belongs to the LED technical field of lamps, is specifically related to that a kind of heat dispersion is good, the household LED light fixture of long service life.
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 LED light fixture with high heat dispersion 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 light fixture of the LED of various moulding.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of have a high heat dispersion LED light fixture, comprise a LED lamp group, be provided with the radiator of plurality of radiating fins, it is characterized in that described radiator inside has a hollow cavity, the outer wall of hollow cavity is provided with the radiating fin that vertical distribution is dispersed, described radiator one end is provided with one and places the recess of LED lamp group, and the other end is equipped with the lamp power joint.
Concretely, 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 along 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 makes an end of radiator form the hollow recess of installing LED lamp group less than the height of radiating fin.
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.
Described LED lamp group comprises the LED illuminator, and the LED illuminator is arranged on the mainboard, and described mainboard is fixedly installed on the metal tube mouth of pipe place of described recess lowermost end.
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, described near offering the heat radiation through hole on the metal tube tube wall of this interface end, described heat radiation through hole is opened on the metal tube tube wall between radiating fin.
Described lamp power joint is electrically connected with LED lamp group by the lead that is provided with in the metal tube.
Described LED lamp group also comprises a lampshade, and described lampshade is printing opacity flat board or sphere cover body, and described printing opacity flat board or sphere cover body setting-in are fixed on the radiating fin of recess outer rim,
Described radiating fin curve-like is in the shape of a spiral radially dispersed along the metal tube tube wall.
This profile main body with high heat dispersion LED light fixture is mainly external radiator, LED lamp group is packed in the recess of radiator one end, other end assembling light fixture power connection, both carry out lead by the radiator hollow cavity and are electrically connected, compact conformation, the radiating fin of radiator is external, the luminescence component of LED lamp group is fixed on metal body one end, can heat be directly passed to radiator by the mode of conduction or radiation, disperse via radiator, heat radiation through hole that simultaneously can also be by the metal body other end carries out heat loss through convection with the heat at the luminescence component back side.
The recess of placing LED lamp group is that a end with the metal body is as the bottom, with the end of each radiating fin as sidewall, therefore its be one disperse but not the cavity of sealing, the heat that the luminescence component of LED lamp group produces can very easily dispel the heat via all directions and radiator, guarantee the normal luminance temperature and the luminescent condition of luminescence component effectively, prolonged the service life of luminescence component.
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 lamp power joint that is positioned at the radiator other end can be general screwed union of family or bayonet joint, more utilizes this LED light fixture promoting the use of in the household field.
The beneficial effects of the utility model are, this LED fitting structure with high heat dispersion is compact to design, good looking appearance, radiating efficiency height, can be applicable to various lights seated connection mouths, obviously improve the configuration design space and the external aesthetic property of LED light fixture, consumer's acceptable degree height can effectively prolong service life of LED lamp luminescence assembly, and applicable to the light fixture of the LED of various moulding.
