Abstract

The utility model discloses a lamp holder heat dissipation structure, its include a lamp holder, one and lamp holder complex shell and with the heat -insulating material that leads of shell, wherein it cooperates in the shell to lead heat -insulating material lower extreme formation annular platform, the bottom surface interval downwardly extending who leads heat -insulating material lower platform has a plurality of heat -conducting plate, and the shell is to being equipped with complex draw -in groove with it by the heat -conducting plate. Heat -conducting plate and lamp holder interval one deck plastic housing utilize this heat -conducting plate to reduce to lead heat -insulating material to the distance of lamp holder, and when the lamp body during operation, the heat conduction of production is to lead heat -insulating material on because the heat -conducting plate is near the lamp holder, the heat can fast transferring to the lamp holder, and then on the lamp holder arrives the lamp holder seat to heat conduction again for the quick effluvium of heat of chip has improved the radiating efficiency, and the radiating effect is good.

Description

A kind of lamp head heat radiation structure

Technical field

The utility model is related to lighting field, specifically refers to the lamp head heat radiation structure that a kind of LED steeps lamp.

Background technology

LED is a kind of semiconductor devices of solid-state, and it directly can be converted into light electricity.LED has small volume, power consumption Low, long service life, high brightness, it is low in calories, environmentally friendly, sturdy and durable many advantages, such as, this causes LED/light source in conventional light source face It is front with big advantage, thus be widely used.The surface area of LED chips is less, and current density is big during work, and uses Often require that multiple LED combinations are formed when illumination, LED closenesses are big, cause chip heat generation density high.And junction temperature rises and can lead Light output is caused to reduce, chip is accelerated to degrade, and shortens device lifetime, it is therefore necessary to be provided with radiator structure and just can guarantee that LED bubble lamps Normally use.

Such as Fig. 1, existing common LED bubble lamp generally relies on heat-conducting piece 4 ' and conducts heat on the shell 2 ' of plastic material Radiated, radiating mode is single, in order to ensure radiating efficiency, the area of described shell 2 ' is general very big, and this also result in The profile of LED bubble lamps makes a big difference with traditional bulb.

In view of this, the design people steeps not attaining in the structure design of lamp for above-mentioned LED and improves many disappearances caused by institute And inconvenience, and deeply conceive, and actively research improvement has a fling at and develops and design the utility model.

Utility model content

The purpose of this utility model is to provide a kind of radiator structure of lamp holder, and it can effectively improve the radiating effect of lamp body Rate.

In order to reach above-mentioned purpose, solution of the present utility model is：

A kind of lamp head heat radiation structure, it includes a lamp holder, a shell coordinated with lamp holder and the heat-conducting piece with shell；Its In：The heat-conducting piece lower end forms annular platform and is matched with shell, and the bottom surface of the heat-conducting piece bottom platform is spaced to downward Stretching has several heat-conducting plates, and shell to should heat-conducting plate be provided with matched draw-in groove.

The draw-in groove is located at the junction of shell and lamp holder.

Each heat-conducting plate is a T-shaped heat-conducting plate.

The circulus that each heat-conducting plate is integrated.

The heat-conducting piece top is the cavity of engraved structure.

After said structure, the utility model in heat-conducting piece bottom platform by having extended downwardly heat-conducting plate, heat-conducting plate The alternating floor plastic casing between lamp holder, heat-conducting piece is reduced to the distance of lamp holder using the heat-conducting plate, when lamp body works, is produced Heat be transmitted on heat-conducting piece, because heat-conducting plate is near lamp holder, heat quickly can be delivered on lamp holder, so lamp holder again Heat is transmitted on bulb socket so that the heat of chip quickly sheds, and improves radiating efficiency, good heat dissipation effect.

Specific embodiment

In order to the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment Row is elaborated.

As shown in Figures 2 to 4, the utility model discloses a kind of lamp head heat radiation structure, in being imposed in LED bubble lamps, should The LED bubble lamp shells 2 coordinated with lamp holder 1 including a lamp holder 1, the wiring board 3, for driving LED chip operations are matched somebody with somebody with shell 2 The heat-conducting piece 4 of conjunction, several are distributed with LED lamp beads and coordinate chip 5, a connection chip 5 and wiring board 3 on heat-conducting piece 4 Dual platen 6 and a cover be placed in heat-conducting piece 4 and chip 5 outside cell-shell 7.

The lower end of the heat-conducting piece 4 forms annular platform 41 and is matched with shell 2, and the upper end of heat-conducting piece 4 can be an engraved structure Cavity 42, cavity 42 is bottom-up to be gradually reduced to form ventilating opening 45, the outer wall of cavity 42 correspondence chip 5 be intervally distributed with substrate 43 so that chip 5 is placed on heat-conducting piece 4, and the upper end of substrate 43 is socketed a connecting cylinder 9, and the top of connecting cylinder 9 is embedded into cell-shell 7 and pushes up On end opening 71；Wiring board 3 is that longitudinal direction is inserted in shell 2, and its upper end is acted against on heat-conducting piece 4, and lower end is connected with lamp holder 1； Dual platen 6 is nested with the top of annular platform 41 and is connected chip 5 and wiring board 3, and the top cover of dual platen 6 puts a cover plate 8；Cell-shell 7 covers are put and are linked together with each chip 5 and shell 2.

It is of the present utility model to it is critical only that：The bottom surface of the bottom platform 41 of heat-conducting piece 4 of the metal material is spaced to downward Stretching has several heat-conducting plates 44, and 2 pairs, shell should heat-conducting plate 44 be provided with matched draw-in groove 23.

The draw-in groove 23 can be located at the junction 24 of shell 2 and lamp holder 1.

The heat-conducting plate 44 is a T-shaped heat-conducting plate, further increases its surface area.

Certainly, the circulus that each heat-conducting plate 44 is also integrated, further increases its contact area with shell 2.

During assembling, heat-conducting plate 44 is inserted in completely in draw-in groove 23, now alternating floor modeling between the heat-conducting plate 44 and 1, lamp holder Material shell body, heat-conducting piece 4 is reduced to the distance of lamp holder 1, when LED bubble lamps work, the heat that chip 5 is produced using the heat-conducting plate 44 Amount is transmitted on heat-conducting piece 4, and because heat-conducting plate 44 is near lamp holder 1, heat can be quickly delivered on lamp holder 1, and then lamp holder 1 is again Heat is transmitted on bulb socket so that the heat of chip 5 quickly sheds.

The utility model on the basis of existing utilization shell 2 is radiated, using the engraved structure cavity of heat-conducting piece 42, heat loss through convection is formed, further also quickly conducted heat on lamp holder 1 using heat-conducting plate 44, bulb socket radiating is recycled, Radiating mode is various, improves radiating efficiency, good heat dissipation effect.

The above, only the utility model preferred embodiment does not limit the scope of the utility model enforcement with this, according to this The equivalence changes that the technical scheme and description of utility model is made and modification, should all belong to the model that the utility model is covered Enclose.
